Using the principle and method of matrix transformation, the matrix model of VRPTW is developed.(3) Through analyzing the time windows and distance matrix of the nodes, we construct a probability transferring matrix, which is used to produce the initial scheme of VRPTW.

以有时间窗的车辆路径问题的矩阵模型为基础，对客户点的时间窗和距离矩阵进行分析，构造了有时间窗的车辆路径问题的概率转移矩阵，并利用基于概率转移矩阵的初始化方案生成方法，产生有时间窗的车辆路径问题的初始化方案。

Considering the mean square of the dynamics longitudinal force on the drawgear as an object function, and considering the rigid impact probability as a constraint condition, the optimizing software named TTCFDOS (Tractor-Trailer Combinations Flexible Drawing Optimization System) has been developed.

在对上述确定性参数系统进行频域分析的基础上，以牵引架上动态纵向力的均方值为评价指标和目标函数，以刚性冲击概率为约束条件，开发了挂接车辆柔性牵引优化设计软件系统TTCFDOS，对挂接车辆的柔性牵引参数进行了优化设计，获得了与挂接车辆经常行驶工况相对应的优化柔性牵引参数

The ideal vehicle convoy is built after the uniformly distributed load is used as the equipollent load. With the maximum function of influence line area under the vehicle convoy, the probability of specific vehicle convoy passing influence line alone and the total weight distribution of specific vehicle convoy, the maximum probability distribution of traffic load effect and under return perild are obtained. Finally, this load model is applied to the example.

模型中把均布荷载作为车辆荷载的等代荷载建立了理想车队，在求出车队影响线面积最大值函数、特定车队单独通过影响线的概率和特定车队总重分布的基础上，得出了车辆荷载效应最大值概率分布和给定评估期的车辆荷载效应最大值概率分布，最后将这一荷载模型应用到实例中。

Because the four-wheeler change direction the turn radius of vehicle obvious small in front rotate toward the vehicle, make the engineering vehicle have to pass sex goodly in the narrow place.

由于四轮转向车辆的转弯半径明显小于前轮转向车辆，使工程车辆在狭窄场地具有良好的通过性。

This four-wheeler change direction system to also have a safety device, be when the four-wheeler change direction vehicle to press system or controller occurrence break down because of the liquid, the safety device will make behind round instauration to neutral change direction, make vehicle reply to general front rotate to vehicle of operation, in order to prevent result in line car of dangerous.

此四轮转向系统亦配有安全装置，当四轮转向车辆因液压系统或控制器发生故障时，安全装置会令后轮恢复至中立转向，使车辆回复至一般前轮转向车辆之操作，以免造成行车之危险。

Its research attracts many authors; therefore, the vehicle type recognition problem is studied. The main researches and results can be described as follows:(1) Vehicle image pretreatment: For the particularity of the vehicle image of this paper, the image pretreatment includes grey scale and background processing.

本文正是在这一背景下，对车型识别的两种算法和识别技术进行了研究，主要的研究工作包括以下几个方面：(1)车辆图像预处理：针对本文研究的车辆图像的特点，车辆图像预处理主要包括图像灰度化和去除背景两部分。

By relaxing the assumption that the vehicle route is Hamiltonian tour for standard VRP, we study the open vehicle routing problem in which the route is Hamiltonian path.

松弛了标准VRP中车辆路线为哈密尔顿巡回的假设，研究了车辆路线为哈密尔顿路径的开放式车辆路径问题。

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。
