Question

请英语高手帮忙翻译下摘要中文翻译成英文，谢谢

我国是农业自然灾害特别是农作物病虫等生物灾害发生严重的国家，农业生物灾害的严重发生，影响和制约农业的可持续发展与农民增收。植物保护工作为农业丰收做出了巨大贡献，起到了保驾护航的作用。但是我国的施药机械、施药技术水平还比较落后，农药利用率低。当前，亟待更新施药机械，改进施药技术，提高重大病虫害的控制能力和水平，以适应新阶段提高农业综合生产能力、建立节约型农业的需要。
在农业生产中，很少使用农药原液进行喷雾，一般都要稀释。原液和稀释用的载体混合后形成溶液、乳浊液或悬浮液。对于溶液，一般仅在开始混合时需要搅拌，而乳浊液和悬浮液的搅拌则应伴随整个喷雾过程。相对而言搅拌乳浊液比搅拌悬浮液要容易，悬浮液尤其是在沉淀了的情况下，再将其搅拌均匀较为困难。所以在整个施药过程中，保持药物的均匀度是非常重要的。
目前我国农民采用的农药搅拌多数是在充好药液的药池内用木棍随便地搅几下，劳动强度高，搅拌效果差，而且药物挥发严重影响农民的身体健康。有的甚至用喷雾器的喷嘴回流冲击以达到搅拌的效果，水药没有充分搅匀就立即喷雾。殊不知药水搅拌不均不仅不能达到农药的预期效果，而且还常常产生受药太浓的植株遭受药害枯苗，太淡的即治不了病虫，如此费时、费工、费药，既增加了病虫抗药性，又耽误了治理时机。因此本文研究设计了一种新型搅拌装置对化学农药的搅拌具有重要意义。该自动搅拌装置，不必增加额外动力，就可解决人工搅拌之苦，还可提高搅拌农药的效果。
本文对搅拌装置叶轮设计理论进行了研究，设计出一种满足液-液、固-液药液基本混合要求的搅拌装置，并对其所产生的搅拌流场、浓度场、临界转速以及流量进行了数值模拟，所做的主要工作有：
1．通过对流体混合理论的研究，设计一种组合搅拌装置；
2．利用Pro/ENGINEER三维软件对搅拌装置叶轮进行三维造型；
3．利用现有的图形软件对搅拌流场、浓度场、临界转速以及流量进行了数值模拟，并考核其搅拌的功率系数，以证明搅拌器设计的合理性；
4．对药池内的流场进行实验研究，并把实验所得到的数据和模拟的数据相对比。
最好不要用软件直接翻译，谢谢啦

China's agricultural crop pest and natural disasters, especially severe disasters such creatures, agriculture and biology disasters occur, the serious influences and restricts the sustainable development of agriculture and peasants' income. Plant protection for agricultural harvests, have made great contributions to the escort. But Chinese pesticide machinery, spraying technology level is relatively backward, pesticide use. At present, the spraying machinery, improved to update the spraying technology, improve the major pest control ability and level, in order to adapt to the new stage of improving the agricultural comprehensive production capacity, building economical agriculture needs.

在农业生产中，很少使用农药原液进行喷雾，一般都要稀释。原液和稀释用的载体混合后形成溶液、乳浊液或悬浮液。对于溶液，一般仅在开始混合时需要搅拌，而乳浊液和悬浮液的搅拌则应伴随整个喷雾过程。相对而言搅拌乳浊液比搅拌悬浮液要容易，悬浮液尤其是在沉淀了的情况下，再将其搅拌均匀较为困难。所以在整个施药过程中，保持药物的均匀度是非常重要的。
In the agricultural production, seldom use pesticides stock to spray, usually diluted. With the carrier and dilution mixed form solution, emulsion or suspension. In general, the only solution to begin to stir, and when mixed with suspension emulsion should accompany the stir throughout the spray process. Relative to mix than mixing suspension emulsion, suspending liquid easily, especially in the case of precipitation, then the uniform mixing more difficult. So in the whole process of pesticide, maintain drug evenness is very important.

目前我国农民采用的农药搅拌多数是在充好药液的药池内用木棍随便地搅几下，劳动强度高，搅拌效果差，而且药物挥发严重影响农民的身体健康。有的甚至用喷雾器的喷嘴回流冲击以达到搅拌的效果，水药没有充分搅匀就立即喷雾。殊不知药水搅拌不均不仅不能达到农药的预期效果，而且还常常产生受药太浓的植株遭受药害枯苗，太淡的即治不了病虫，如此费时、费工、费药，既增加了病虫抗药性，又耽误了治理时机。因此本文研究设计了一种新型搅拌装置对化学农药的搅拌具有重要意义。该自动搅拌装置，不必增加额外动力，就可解决人工搅拌之苦，还可提高搅拌农药的效果。
At present the most stirring farmers using pesticides in liquor is good medicine with a stick in the pool, stir casually, mixing effect of high labor intensity, and the serious influence drug volatile farmers health. Some even with spray nozzle to the impact of backflow mixing effect, water medicine without sufficient agitate immediately spray. But not only cannot achieve uneven mixing potions pesticide expected effect, but also often affected by medicine too thick plants suffer phytotoxicity of light, too dry seedling diseases, don't try to so time-consuming, FeiGong, medicine, which can increase the cost, and the disease resistance to delay the time management. Therefore this research design, a new kind of device for chemical pesticide agitation is of great significance. The automatic device, don't add an extra motivation, it can solve the artificial stirring, which can improve the mix pesticide effect.

Answer 3

China's agricultural natural disasters, in particular bio-crop pests, such as disaster-affected countries, of agricultural biological disasters occur, the impact and constraints to sustainable agricultural development and peasant incomes. Plant protection for agriculture has made tremendous contributions to harvests, have played a role in escorting. However, the application of our machinery, application of technical level is still relatively backward, pesticide utilization rate. At present, the need to update the application machinery, improvement of application technology to improve the control of major pests and diseases and level of ability to adapt to a new stage of improving agricultural production capacity, the establishment of a conservation-agriculture needs.
In agricultural production, little use of pesticides to spray liquid, usually diluted. Diluted with liquid and mix to form a carrier solution, emulsion liquid suspension. The solution is generally only required at the beginning of stirring mixture, and the emulsion and suspension should be accompanied by the mixing process of the spray. Relatively emulsion than stir stirring suspension is much easier, especially in the suspension of the case of precipitation, and then even more difficult for the mixing. Therefore, throughout the application process, to maintain uniformity of drugs is very important.
China's farmers to adopt the majority of pesticide mixing liquid in the filling of the drug a good pool and stir lightly with a wooden stick several times, and high labor intensity, the effect of poor mixing, but also severely affected by volatile substances of the physical health of farmers. Some even return to the impact of spray nozzles in order to achieve the effect of stirring, water mix drugs without adequate spray immediately. Realize that medicine can not reach the uneven mixing of the desired effect of pesticides, but also often produced by plants subjected to drug injury too dry Miao,太淡that the worms can not cure, so time-consuming work, drug costs, an increase of both pest resistance
Nature and timing of delayed treatment. In this paper, the design is therefore a new type of mixing device mixing of chemical pesticides is important. The automatic stirring device, do not need additional motivation, we can resolve the pain of manual mixing, but also to improve the effectiveness of pesticide mixing.
In this paper, the design of the impeller mixing device theory research, design a solution to meet - liquid, solid - liquid liquid mixing requirements of the basic mixing device, mixing the resultant flow field, the concentration field, the critical speed and traffic the numerical simulation, the major work done:
1. By the theory of fluid mixing research, design a combination of mixing devices;
2. The use of Pro / ENGINEER software for three-dimensional impeller mixing device for three-dimensional modeling;
3. Use of the existing graphics software for mixing the flow field and concentration field, the critical flow speed, as well as a numerical simulation, and evaluation of its stirring power factor, designed to prove the reasonableness of blender;
4. Tanks on the drug for experimental study of flow field and laboratory data and simulation data compared.
