The central government came to a new high level of recognizing the science and technology after 1978, thus, a new policy of clerisy was established and a good political atmosphere, which benefits on popular science development, was formed. Besides, while the government's essential mission was transferred to economical construction, the popular science was accelerated by factors as economical development, social desire and economical treatment. Then, the prosperity of education set a good foundation for the development of popular science. Fourthly, the increase in the number of boffins and a fast advance on science and technology contributed to popular science's development intellectively. All these elements above caused the 2nd fastigium. However, during the last 1980s and early 1990s, confusion occurred to man's sense of worth in the period of economy transformation, which made popular science come to a downturn. As a result, the 2nd fastigium declined.

第四章对第二次科普高峰进行了分析。1978年以后，党中央对科学技术的认识达到了前所未有的程度，确立了新的知识分子政策，形成有利于科普发展的良好政治氛围；国家工作重心转移到经济建设上来，经济发展、社会需求和经济待遇等因素促进了科普的发展；文化教育事业的兴旺发达为科普的发展奠定了良好的基础；科技工作者队伍的壮大，科学技术的迅速发展，提供了科普发展的智力支持，这些综合因素促成了第二次科普高峰的到来。80年代末期到90年代初，由于在经济转型期出现了暂时的价值观混乱，科普工作陷入低迷，科普高峰消退。

Researches show that the drive force characteristics of the electric tractor drive system based on series DC motor is close the ideal characteristics, the curves are concave, low speed with constant power, and high speed with constant torque; the electric tractor has large working speed under different shifts, but the extensive coincidence speed shows that the variable ratio of the gear is unreasonable; the maximum climbable gradient of this electric tractor is more than 30%, and does not need frequent shift when working for its extensive climbable gradient; there are many influence factors of continuous working time, which the more obvious factors are working speed and working load, the working time increases with the increase of the working speed and working load.2. Simulation researches on the drive characteristic of the electric tractor.

研究结果表明：基于串励直流电动机(来源：ABC21论文网www.abclunwen.com)的电动拖拉机电驱动系统的驱动力特性场接近理想驱动力特性场，其各挡下的驱动力特性是一组下凹的曲线，低速恒转矩，高速恒功率；同一行驶速度下所对应高挡驱动力大于低挡驱动力，这是由电机的调速特性决定的；电动拖拉机各个挡位下具有较广的稳定作业速度范围，但是各个挡位之间速度重合的范围较多，说明所用变速箱变速比与电动机匹配不合理；电动拖拉机最大爬坡度达到30%以上，并且各挡爬坡度变化范围较广，作业过程中不需要频繁换挡；影响电动拖拉机连续作业时间的因素较多，其中作业行驶速度和作业负荷影响最为明显，作业负荷越大，连续作业时间就越短，作业速度越快，连续作业时间就越短。2、电动拖拉机驱动特性仿真研究。

Therefore, the torque required to open the gate valve required torque than the closure of large, in addition, for a pair of contact between the sealing surface, the Non Rising Stem Resilient Seated Gate Valves coefficient of static friction between them than the dynamic friction coefficient, to make them from the static state generate the relative movement is required to exert greater force to overcome the static friction; due to temperature changes, so that the sealing surface pressure between the larger, need to overcome the static friction force also will be bigger, so that when you open the valve on the stem nut on the sometimes increase the torque exerted a lot.

所以，开启闸阀所需的力矩比关闭闸阀所需的力矩大，此外，对于一对互相接触的密封面来说，它们之间的静摩擦系数也比动摩擦系数大，要使它们从静止状态产生相对运动，需施加较大的力以克服静摩擦力；由于温度变化，使密封面间的压力变大，需要克服的静摩擦力也随之变大，从而使开启闸阀时，对阀杆螺母上施加的力矩有时会增大很多。" Moment analysis of valve operation "是由中国闸阀网提供的国际阀门新闻，译文仅供参考。另外，中国闸阀网还提供相关产品搜索：闸阀型号、闸阀价格、闸阀技术、闸阀新闻、闸阀生产商等。

If the projections are accurate, and the weak dollar boosted international commodity prices on the one hand, China's imports increased costs; On the other hand, makes the economic benefits of the sale of raw material deterioration, more willing to expand production, increase the supply of global tensions.

The results show that the increasing Marangoni number will lead to more nonlinear distribution of temperature field, but streamfunction of the cell center; vorticity on the wall and peak value of velocity diminish first, then increase, finally lose stability. The thermocapillary convection in the whole liquid zone appears to get stronger along with the augmentation of Prantal number. The effect of increasing of Biot number on temperature and flow fields is not obvious although the convection is strengthened a little. As increasing the aspect ratio A, thermocapillary convection induced by temperature gradient and liquid viscosity becomes stronger.

结果表明：温度场的非线性分布随着Ma数的增大而加剧，但对流涡胞中心流函数、壁面涡量和轴向、径向速度峰值并不象温度场随着Ma数的增大而单调增大，而是先减小，然后增大，最后失稳，表明Ma数对热毛细对流的影响比较复杂，针对不同的物理模型，会导致完全不同的流态；Pr数愈大，流体的热扩散能力在粘性扩散与热扩散能力之比中愈占支配地位，当Ma数一定时，热毛细对流随Pr数的增大在整个液体区域内有增强的趋势；Bi数增大，热毛细对流有所增强，但不甚明显；A的增大使得由温度梯度和流体粘性诱导的热毛细对流随之增强。

In 1962, Peter Drucker, the famous master of economics and management, presents definitely that logistics was the last area for decreasing cost in his paper Economy"s Dark Continent published in fortune. For 40 years, the concept of logistics was expanded continually and more and more attentions were paid on it. Especially from middle of 1980"s to this day, with the increase of economic globalization and development of the information technology, more and more enterprises go back to their main businesses, and pay their points on these businesses such as product development, manufacture, marketing, which are their core businesses and they are good at. These businesses embody the competitive advantages of the enterprises.

1962年著名经济管理学大师彼得·杜拉克在美国《财富》杂志上发表《经济的黑暗大陆》一文，首次明确地提出物流是节约成本的最后领域。40年来，物流的概念在不断地拓展，人们对物流管理越来越重视，特别是80年代中期至今，随着经济全球化竞争的加剧、信息技术的飞速发展，许多生产企业回归主业，将精力集中于产品开发、生产、销售等具有竞争优势的核心专长业务的呼声日益高涨，理论界和企业界已不再浅层次的探讨物流管理的重要性问题了，他们开始探讨物流管理的模式问题，即：究竟是自营物流业务，还是将物流业务外包给专门从事物流管理的企业去做。

To accelerate the widespread of Synchronous Chip Seal and improve the operation quality of Synchronous Chipsealer, key techniques which influence the operation quality is studied detailedly, including the control of distributing quality, the dynamics characteristics of hydraulic system and the spray characteristics of asphalt nozzle of Synchronous Chipsealer.1 The factors which influence Synchronous Chip Seal quality are studied.
