关于激光制导炸弹的问题

电视里军事新闻里我们经常会看到这样的镜头：黑白的画面当中，十字瞄准具正对准目标。数秒钟后，炸弹或导弹从视角的另一个方向飞向目标，之后引发了巨大的爆炸，目标被摧毁。我的问题是：
1. 现实中存在制导“炸弹”，那“导弹”有利用激光进行制导的吗？
2. 是否需要两架飞机完成激光制导炸弹的投弹任务？一架负责投弹，一架负责激光指
引。
3. 我们知道，光投射到粗糙的物体表面（如建筑物的墙面）会形成漫反射。那投弹时，
如何确保有足够强烈的激光被弹头的接受装置接受到接受到？

谢谢！

Answer 1

1.当然有激光制导导弹，武直10所配置的红箭10就是激光制导反坦克导弹。激光制导是现代导弹最常用的制导方式之一。
2.找你所说是可以的，甚至不用2架飞机，由地面不对用激光照射器照射目标也可以对战机所发射的激光制导导弹进行导向。另外，战机自身也可以带激光照射吊舱，对自己所发射的导弹进行目标指引，这些都是可行的。
3.首先可以增大照射激光的功率，其次可以改进导弹激光导引头的敏感度，这些都不是太大的难题。

Autumn and Winter greenhouse strawberry cultivation techniques pollution

Period,Ralph Lauren Greenhouse Malan outside the cultivat, picking fruit promptly after drip irrigation, soil moisture content to field up to the maximum field capacity of 60% to 80%. 4. C02 gas release fertilizer in winter Chung quarters, greenhouse generally remain closed state, the lack of indoor CO levels, reducing the photosynthetic efficiency of strawberry, the production decline, Editor of product: Min E-mail: wangm @ a. ac. cn Tel :010 -51,503,567 Fujin City, Heilongjiang Province, real estate supply of watermelon in the past normally in early August to mid-September, Liaoning and off the watermelon also impact the local market, the economic benefits of Watermelon is often a Selling what you do, proud parent of the melon as long-distance trafficking If the watermelon supply period was extended to October 1, to achieve Kitauri south, both added in Harbin, Shenyang, Dalian, Shanghai,Ralph Lauren, Guangzhou and other cities off-season market supply, increased income Watermelon is the development of melon The Machang You, Wang Guangyu, Heilongjiang Fujin Agricultural Technology Promotion Center, 1561O0 Jilin, Heilongjiang Myer Seed Industry Co., Ltd., 156 100, such as. = Volume Machang You Jilin Wang Guangyu economic good way. The author sums up the last five years late autumn watermelon cultivation techniques, the purpose is to guide the scientific use of regional advantages to develop the local Watermelon watermelon production, improve Watermelon melon enthusiasm, moving from the weak to strong, from early to delayed development, from local sales to extension of other towns. A selection block 1. The election to late autumn cold watermelon cultivation, we must first consider the prevention of waterlogging and control water. Also make full use of geographical advantages, select hillock, deep sandy loam soil and planted the black loam. 2. Selected crop of wheat,Ralph Lauren, corn, beans and other crop after planting watermelon is better, easy to grow vegetable Crops, melon crop is not Huan g an technological innovation; a clamor hug l ÷ |. Fog Caipei technology with species, generally 6 to 8 rings for once. Bean crop planting watermelons to identify the type of herbicide use to avoid injury. Two scientific fertilization late autumn than early watermelon watermelon field longer growing season, 15 ~ 20d, so to ensure adequate supply of plant nutrients and fruit growth and development, to avoid the growing phenomenon of late due to premature aging Tuofei appear. Fujin local experience combined with fertilization to take the following measures: ① rake in the spring before the fall turn, each 667m2 of high quality farm composting facilities 1t3000kg, DAP 15kg, potassium 4 ~ 5kg, 50kg cake as a base fertilizer. ② applied before planting each Nei'an quality farm IElOOg, DAP 60g, fermentation cake 50g, 20g of potassium sulfate as a germplasm becomes poor, need to release CO: gas fertilizer. In the strawberry into the reproductive stage, one cast of solid CO: gas fertilizer, the soil per square meter greenhouse facilities within 2 points per hole to put 10g of solid CO: gas fertilizer, and wet soil mixing, 30d in the application, then cast the first 2 solid CO: gas fertilizer, the same number of 1st. Second, the chemical reaction method, put a greenhouse in every 50rn plastic bucket placed on top of strawberry growing point,Ralph Lauren, 30min after sunrise every morning, put the container industry from the 96% sulfuric acid after sulfuric acid diluted 5-fold 340mL, ammonium bicarbonate 105g, produced CO: photosynthesis to meet the need of ventilation before the strawberries. 5. Artificial pollination of artificial pollination, with increased production 22% to 28%, reducing the role of the number of abnormal results. 10 am to 3 pm, with a brush gently brushed from strawberries to spend every 1 ~ 2d operation 1. 6. Artificial fill, the depths of winter warming spring insufficient light in the greenhouse every 20m, 1.5 ~ 2m above the ground to install a 100W incandescent, rainy days and evening to make up light. Hanging in the greenhouse Iiii reflective screen, increase the temperature. 7. Plant Adjustment regular removal of old leaves, diseased leaves,Ralph Lauren, dead leaves and concentrated fire, to reduce the incidence of disease, increasing light. Before flowering, bud separation phase Thinning 1,5 ~ 1 / 4 section-bit high-bud, young fruit green phase in deformed fruit thinning and pest to fruit, to ensure focus on the supply of nutrients to improve yield and marketability. 8. The main pest control strawberry gray mold disease is, to improve efficiency and reduce greenhouse anti-humidity, 10% off selected gram of dust and other agents the best in the evening when the powder control, the amount of time each 6671TI 1kg, every 7 ~ 10d dusting 1, 3 to 4 times continuous control. Or use chlorothalonil, procymidone aerosols in the evening light control. Fourth, the harvest harvest time in the morning dew has dried to a temperature not reached before noon or evening, when the harvest with the thumb and forefinger and snap off the stalk, together with part of the stalk off. According to distance sales, in the fruit surface color 80% and 90% harvested, graded and packed and sold. Group

Chrysanthemum flexible water dish

However, green for the evaluation, total score of 1O0 points, scoring five individual evaluation, the arithmetic average of the results in Table 1: wrapped in a different color protection agents and food products with the color of chrysanthemum ■ the impact of color protection agent is (%) combined effect of (sub) zinc acetate + 0.03% zinc acetate, sodium bicarbonate 6% 72 0.02% zinc acetate, sodium bicarbonate, sodium bicarbonate 6%, 0.03% magnesium chloride + magnesium chloride, sodium bicarbonate 6% magnesium chloride 0.02% sodium bicarbonate, sodium bicarbonate 6% magnesium chloride zinc acetate zinc acetate + O. 03%, 0.03% magnesium chloride, sodium bicarbonate sodium bicarbonate 6% zinc acetate + O. 88 02%, magnesium chloride O. 02%,MBT outlet, 6% sodium bicarbonate 78 can be seen from Table 1, both in the pickling process by adding zinc acetate O. 03%, 0.03% magnesium chloride, sodium bicarbonate 6% combination of the best color protection agent, from the basic finished dishes to maintain the original tender green chrysanthemum natural color, and a single zinc acetate, magnesium chloride, sodium bicarbonate added protection color can not maintain its original natural green. This is because the chlorophyll in the leaves of chrysanthemum dishes in salt and alkaline conditions, and zinc ions, magnesium ions that produce more stable chlorophyll and chlorophyll magnesium zinc sodium sodium, which can maintain a relatively solid green,MBT outlet, even after 100 ~ C 10rain boiling water sterilization, but also to maintain most of the green. 23 pickled vegetables after desalination as chrysanthemum high salt content, taste salty, is not conducive to human health, pickled vegetables, salt does not conform to the current direction of development. So we dish of pickled chrysanthemum after the desalination process to reduce its salt content. Is in stainless steel tanks in accordance with the amount of vegetable water ratio of 1:4 by adding water, desalination of about 6h until the dish is detected in the salt content ≤ 2%, stop desalination. In order to prevent decomposition of chlorophyll, pH, pool water must be kept I> 7, and desalination in the dark dark. 2.4 rinse water desalination and control of chrysanthemum dish after rinsing with water to the surface of the salt residue and color protection agents, and to the surface with the centrifuge control free water. 2.5 Weighing and bagging the rinse, water control after the chrysanthemum dish quantitative in plastic bags and add seasoning sauce, keep the broth pHI> 7. Note that bags of food must be dedicated and can withstand 1oo ℃ boiling water sterilization of cooking bag. 2.6 after the vacuum sealing bag sealing machine sealing. Vacuum sealing machine work 1> 0. O9MPa. 2.7 sterilization and cooling the packaged food product by daisy 100 ~ C boiling water sterilization, heat 10min. In clean, cold water pool to cool to 35-40 ~ C, they can dry out the surface water control,Ralph Lauren shop Shanghai pumpkin resources and t, final inspection, packing storage. 3 Results and discussion 3.1 daisy-fresh vegetables by pickling, can achieve the purpose of storage and preservation of pickled vegetables to maintain good chrysanthemum good appearance and color, aromatic and rich chrysanthemum,MBT outlet, 14d in the future can be pickled as a semi-finished raw materials needed to provide water packaging Chrysanthemum food production, preservation can be a long time to solve the water in processing food packaging materials daisy seasonal problem. 3.2 This test obtained by a daisy for pickled vegetables of the new technology of the new technology is characterized by a pickled and pickled while adding color protection agents, the technology lies in the choice of color protection agents. The testing to determine water use food packaging chrysanthemum 0.03% zinc acetate, magnesium chloride 0.03%, 6% sodium bicarbonate combination of better color protection agent, it can maintain the natural chrysanthemum green vegetables, and did not change the chrysanthemum dish The original taste. 3.3 new process technology than the traditional pickled vegetables reduces the production processes, shorten production time, thus saving the cost of new technology products were better than the traditional process sensory processing products, and other physical and chemical health indicators are relatively similar. According to Wencheng CDC inspection reports, the appearance of flexible packaging products chrysanthemum dish of water was light green, short segments, leaves, tender texture, with rich fragrance of chrysanthemum dish, coliforms ≤ 3O, Shigella, Staphylococcus aureus , Salmonella, hemolytic streptococcus was not detected, pickled vegetable products meet health standards. 3.4 chrysanthemum dish of water to meet modern vegetable processing flexible packaging product development Fang Xiangju cauliflower flexible packaging uses desalination water or broth,MBT outlet, add water, then cooking the food bags, vacuum sealing, the finished product after sterilization and other processes, its beautiful appearance, Chrysanthemum intuitively natural color and shape of food, atmosphere with modern products, and convenience food, open bags of salad or cooking can meet city's fast-paced modern life, good market prospects. 3.5 The significance of the success of product development, packaging water food product development success of chrysanthemum, chrysanthemum dish for storage and transportation, and sale of great significance, to promote the development of local farmers, specialty vegetables, significantly improve the social and economic benefits.

有。激光制导炸弹的射程甚至可以达到80km。导弹也有激光制导的。同时导弹还有另外的激光假束制导方式。
不需要两架飞机。一架飞机可以携带激光炸弹和激光照射吊舱。也可以由地面特种部队提供激光制导。
激光的亮度是相当高的，炸弹上的激光接收器也是相当灵敏的。即使漫反射，激光的功率也够了。
