You know the truck has its forced date of retirement, that is depreciation cost, insurance cost, annual examination fee are necessary to be spent on the truck, and the sum is high. With time passes, the repairing cost and the time delated by the repairment will increase year after year. So the truck ownerr should get the capital back in the first two years. The running of the truck and the ruuning environment will advance the repairing date; are your trucks can make money according to the seasonal goods resource and total transport power?

你是知道的汽车是有强制报废期限的也就是每年有车辆折旧费、加上保险、营运、年检这些费用合计并不低，随着时间的推移车辆维修费、修车耽误的时间会逐年递增，所以一般经营货车的人应在头两年把购车等本金赚回来，你的车辆行驶和使用环境导致维修期会提前，根据你们那里季节性的总货源和总运力你两个车能否赚到钱？

Static VRP method which fix on the route before the vehicle running is not suitable to solving the Port Storage Vehicle Routing Problem, because it is disaccorded with the realities.

对于集装箱码头堆场车辆调度问题，若用静态路径问题的方法解决，将车辆路径在车辆行驶前就确定下来，不符合实际情况。

In addition to transforming the existing facilities as trucks and stations, large number of locomotives and trains need to be replaced. Passenger trains at a speed below 160km/h will be obsoleted gradually. More comfort able and stable trains will put into use.

铁路提速除了需要对线路、车站等基础设施进行改造，大量机车、车辆也面临着更新换代，速度低于160km/h的客车车辆将被逐步淘汰，取而代之的是稳定性和舒适性更好的高速客车车辆。

The brake system is the instrument of reducing speed during vehicle going,stopping or stationing at up-slope,which is important part of vehicle and relative to the security of vehicles.

制动系统是车辆行驶过程中降低行驶速度、停止行驶或在坡道上停车的装置，是车辆的重要的部件，它直接关系到车辆的安全。

Suppose you are running a car at a constant speed with a constant curvature, if you then keep the steering wheel in the same position and increase the car speed gradually, then if the car wants to run on a circle with a smaller radius the car is said to be oversteering, if it remains on the same radius it is neutral and if the car goes to a wider circle it is understeering (for that speed and curvature!).

假设你以固定的速度沿固定曲率的圆周驾驶车辆，然后你保持方向盘角度不变，逐渐增加车辆的速度，此时车辆行使的半径如果变小，称为转向过度（在这个特定的速度和曲率下！）。这个测试还有不同的做法。

Firstly, this paper analyzes the transmission style of diving machine in detail and selects hydrostatic transmission as transmission manner of Heavy Engineering Transporter. Then we analyze the principle of hydrostatic transmission, control style of hydraulic components and the basic driving theory of transporter and pay attention to solve the problems of driving speed-regulation control when transporter runs on different road surface and differential speed control ensured every wheels pure roll when transporter is in swerving.

接着分析了静液压传动的液压原理、静液压传动液压元件的控制方式和汽车行驶理论基础，主要解决了以下控制问题：(1)车辆在不同工况下行驶时，选择不同速度的整车调速控制；(2)车辆转弯时，为确保车轮实现纯滚动，而使各驱动轮按设定规律运动的差速控制；(3)车辆从一坡度过度到另外一坡度时，使每个驱动桥实现同步的桥间差速控制。

Height data such as maximum, minimum and average height in every height block are calculated by a scan-by-scan height evaluator 38 on the basis of the linked height data and vehicle position information, and a vehicle type detector 40 detects the type of the vehicle.

有关每个高度块高度的极大、极小和平均高度由一个逐步扫描评估器38根据链接高度数据和车辆位置信息进行计算，一个车辆类型检测器40检测车辆的类型。

Each are big on introductory world the company recombines a circumstance in the production of domain of car of orbit of low floor city, analyse each big company holds share in place of this one market, compare the characteristic of the low floor car of height of different floor board, give out the piece price of typical car and technical parameter.

介绍世界上各大公司在低地板城市轨道车辆领域的生产重组情况，分析各大公司在这一市场所占份额，比较不同地板高度的低地板车辆的特点，给出典型车辆的单位价格及技术参数。

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。
