惯性是物理学中一个非常重要的概念。对于惯性的认识,目前比较认同的理解是:物体具有保持原有运动状态的属性,即惯性(使物体保持静止状态或匀速直线运动的状态的性质)的原因并不在物体的内部,也与力无关。而是由于物体所处的时间均匀性与空间对称性。随着现代物理学的发展,广义相对论又提出:惯性是由其表现物体周围存在着的与时空有关的天体质量分布情况决定着的性质。对于惯性认识的一个重要进展还有惯性与能量的关系。能量具有惯性的观点拓宽了对于惯性的认识,也拓宽了对于能量的认识。
本文以惯性本质为研究视角,通过阐述惯性概念的发展和变革、人类对自然界各种惯性现象的认识来拓宽对惯性的理解,侧重以牛顿经典时空观为基础来探索惯性定律的成立条件及在中学物理中惯性概念、惯性定律的教学,把握惯性和生活的密切联系,介绍惯性在科技上的应用。

楼主你好,下面就是翻译
Inertia is a very important concept in physics. For the inertial understanding, the identity of the understanding is: object has to maintain the original motion state property, i.e. inertial (nature tends to maintain a static state or the state of uniform linear motion.) the reasons are not on the interior of the object, also with the force. But because the object the time symmetry and spatial. With the development of modern physics, general relativity is proposed: inertia is by the nature of objects surrounding the existence of the related to time and space distribution determines the quality of celestial bodies. For the inertial understanding of an important progress and momentum and energy relations. Energy has the inertia view broadens the inertia of the understanding, but also broaden the understanding of the energy. {{#bl#}} based on the inertial nature as the research angle of view, through the development of the concept of inertia and change, human understanding of the nature of various inertial phenomenon of inertia to broaden understanding, focus on the establishment conditions to explore the law of inertia based on Newton classical space-time view and teaching physics concept of inertia, the law of inertia in, close contact grasp the inertia and life, application of inertia in the science and technology.

Inertia is a very important concept in physics. Understanding of inertia, the more recognition of objects with properties of keeping original motion state, the inertia (object will remain at rest or of uniform motion in a straight line), the nature of reason is not in the interior of the object, also has nothing to do with force. But due to the uniformity of the object of time and space symmetry. Along with the development of modern physics, general relativity and proposed that inertia is around by its expression objects associated with space-time quality distribution determines the nature of the object. An important progress for inertial understanding of relationships with energy and inertia. With inertial energy point of view to broaden the understanding of inertia, also broaden the understanding of energy.
Based on inertial essence as the research perspective, this paper expounds on inertia of the concept of development and change, human understanding of nature of various inertial phenomenon to broaden the understanding of inertia, focusing on the based on the Newton classic time-space conditions to explore the establishment of the law of inertia and the inertia in the high school physics teaching concept, the law of inertia, grasps the inertia and life closely related, introduces the application of inertia on the science and technology.

食物是一个国家生存的物质基础,食品安全事件可以影响到国家的稳定和经济发展,小的可以危及个人的生命和健康。近年来,中国的粮食安全形势不容乐观,从而导致食品安全事故频繁发生,导致国内消费者对食品的信心下降。代不仅在食品生产过程中存在的食品安全风险,但在流通过程中也提出了从农场到餐桌。社会关注食品安全的相关指标大多集中在食品农药残留,食品添加剂,食品生产和加工相关的指标,往往忽略了运输,贮存污染,食品污染和保存老化的食品物流问题。由于缺乏安全意识,食品物流,加上原中国的有关法律和法规的食品物流的标准化是不够清晰的不完善。落后设施和信息技术的发展水平等原因,已生产后的质量标准的食品,经常在运输,仓储,配送,销售等流通过程中,缺乏必要的保护,温度适宜湿度,发生变质,腐烂,甚至其它有毒物质污染。
食品物流和安全问题的研究和分析,可以帮助推进现代化的食品物流行业的过程中,以防止恶化食品质量标准,在流通过程中被污染。此举不仅在国家和社会的稳定发挥了基础作用。同时促进粮食物流业,以满足消费者对食品质量的需求的快速发展,提高食品企业,食品物流企业乃至整个食品行业的竞争力。
本文通过分析中国食品安全的物流状态,确定存在的问题,并借鉴西方的成功经验,并提出解决方案,全方位提高食品物流的质量,减少安全风险食品物流,食品物流安全保障。
