The front wheel of this vehicle not only must satisfiedly steering request, but also must satisfy the actuation the request.

近年来，四轮驱动汽车开始迅速普及，WH2040这样一款越野车同样采用的是四轮驱动。

In the calculation and design module, the design of every component part can be carried out by a parameter driving conception mode, i.e. obtaining concrete mode by seriate dimensions driving. In NC programming, based part feature three cutting forms can be selected.

在设计计算中，各零件的设计采用参数驱动的概念模式，由系列化的尺寸参数驱动产生具体模型；在数控编程中，根据零件的特征，系统提供了三种粗切削的方式。

"We are also in the concept development stage of a camless actuation device that will be packaged with a cylinder head module that includes valvetrain components,"said Srinivasan.

&我们还在构想开发一种无凸轮驱动装置，这种装置将由汽缸盖包裹并包括气门传动零件，& Srinivasan说，&这整个的驱动装置将包括汽缸盖或汽缸盖的一部分。&

Finally, the customer-driven costs are greater for expensive categories, whereas the firm-driven costs are greater for categories with many stockkeeping units.

最后，昂贵产品类的顾客驱动型成本更高，而包含存货单位的产品类的企业驱动型成本更高。

The subdividing drive is a kind of driving technology that can effectively improve the step precision and characteristic of low frequency.

细分驱动技术是一种有效改善步进电机低频特性和提高步进精度的驱动技术。

Take the 10~12ml single-valve capacity as the example, with flings turns the head to separate evenly, 36.000rpm 60 the hour, turns the head with the angle type to separate 45, OOOrpm 36 the hour, the former including adds the deceleration to use in common 130,000,000 revolution of actuation department lives, the latter must use 100,000,000 revolution of actuation department lives, this was 100 ~ 20,000,000,000 transfers to at that time the supercentrifuge total life looked, without doubt each time tests the expense to be excessively high, in addition the CsCl amount used are many, price expensive and so on factors, causes this kind of separation purification work to become the very expensive experiment.

以10~12ml单管容量为例，用甩平转头分离，36.000rpm 60小时，用角式转头分离45，OOOrpm 36小时，前者包括加减速在内共用去1.3亿转驱动部寿命，后者也要用去1亿转驱动部寿命，这对当时超速离心机总寿命为100~200亿转来看，无疑每次实验费用过高，加上CsCl用量多、价格贵等因素，使这类分离纯化工作成为非常昂贵的实验。

The ticketer machine of this system is the highly integrated system that our company developed, it includes such parts as the shell, software, thermal printer, computer, LCD, touch- screen, etc., the company has already initialized the software into the computer before the products are dispatched from the factory, to be convenient for the users (drivers that have all already backed up in the hard disks of the computer, and the driver of the special-purpose expansion card), at the same time, our company can make special modification according to the request of the user, meet the customer's demand.

本系统的取票机是我公司开发的高度集成系统，它包括机身、软件、热敏打印机、电脑、液晶显示屏、触摸屏等部件，公司在产品出厂前已将软件初始化进入主机，这样省去了用户的麻烦（电脑主机的硬盘中都已备份好电脑的全部驱动程序，以及专用扩充卡的驱动程序），同时，我公司也可根据用户的要求进行特殊定做，满足客户的要求。

Fuel saving ratio in 2 typic circulations reaches 45.6% and 33.5% respectively.Artificial model and control strategy can meet the design requirement of driving system for the hybrid electric bus.

为提高整车性能的可靠性，对驱动系统进行建模和仿真研究是非常必要的。1驱动控制系统组成及工作模式PHEV混合动力

The unfeasibility of discrete event driven simulation for high-speed network is discussed; two simulation algorithm based on time driven simulation are given, one of which is as precise as that based on discrete event simulation, but is faster, and the other gets less precision, but is much faster than the former. Comparing with the algorithm based on time driven fluid simulation, both of the proposed algorithms support the succeeding simulation for high-level protocol.

其中一种算法在精度上与离散事件驱动仿真算法一致，但仿真速度明显加快，另一种算法存在一定的仿真误差，但仿真速度要高得多；与时间驱动的流体仿真相比，这两种方法都是针对离散系统的仿真，能提供对上层协议仿真的支持。

However, the control performance of the PMSM drive is still influenced by uncertainties, which usually features parameter variations, external load disturbances, unmodelled and nonlinear dynamics. To achieve high-performance PMSM drive, which has great ability of adaptation and better performance against disturbances, advanced control schemes have to be developed to deal with these uncertainties.

然而，由于永磁同步电机驱动系统受电机参数变化、外部负载扰动、对象未建模和非线性动态等不确定性的影响，要获得高性能的永磁同步电机驱动系统，必须研究先进的控制策略以解决这些不确定性的影响，使系统具有较强的自适应能力和抗干扰能力。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
