动力分配系统

3Through analysis of the calculate results and actual fact of Shaanxi province, we can still attain below information: The latest rank of index of new economy in China shows: Shaanxi is the eighth, but the GDP per person is NO.29, so the technology and resource advantages of Shaanxi are far to convert to economic advantage, Finally, how to make the technology of the Shaanxi converting to realistic productivity farthest, and make the technology advantage converting to economic advantage, and make the big province of technology becoming a powerfully economic province which is worthy of the name, the dissertation suggests grasping a few aspects as follows: Set up the idea of exploitation new technology, establish the motive mechanism of technology innovation, establish the mechanism of guarantee the budget of scientific research, establish the mechanism of guarantee scientific personnel, construct the fair competition market environment, allotment technology resources openly in the most possible, make the resources to be allotted and used with high-efficiency, at the same time, relying on the resources advantage of Shaanxi, proceed the technique reform and technique penetration, so as to creates the higher benefit.

最后，就如何使陕西的科技优势最大限度地转化为现实生产力，使科技优势转化为经济优势，使科技大省成为名副其实的经济强省，笔者建议从以下几个方面抓起：树立新的科技开发观念、建立科技创新的动力机制、建立科研经费保障机制、建立科研人员保障机制、营造公平竞争的市场环境，科技资源分配尽可能地公开，使资源得到较高效率的配置和使用，同时，依托陕西的优势资源，进行技术改造和科技渗透，以创造出更高的效益。本研究具有以下创新点：一是使用先进的研究方法，把计算机计算和新的数学方法相结合，使计算简单化、准确化；二是使用了先进的研究思路，把陕西省和其他地区置于同一系统内，使用同一的数据处理方法和统计口径，使计算结果更科学、更符合实际，且具有可比性。

The transformation of the yaw moment under differential brake and the impact of the slip ratio and road surface friction coefficient to the yaw moment were analyzed. The distribution method of the brake force was confirmed. After analyzing the observability of the control system, the state observer was designed, the evaluation of the side slip angle was completed and result of the evaluation wan validated.

本文分析了差动制动时整车横摆力矩的变化情况，研究了滑移率和路面摩擦系数对横摆力矩的影响，确定了制动力的分配原则，进行了控制系统的可观性分析，并设计了状态观测器，完成了质心侧偏角的估算并对此估算结果进行了验证。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
