Based on the theory of construction machinery, this paper establishes the mathematical model to forecast wheel loader tractive performance. By using relative software, it compares and analyzes calculated result and test result so as to validate the right and the science.

本文主要以工程机械理论为基础，建立轮式装载机牵引性能预测的数学模型，利用相关的性能预测软件，把软件计算的结果和试验结果加以对比、分析，从而验证数学模型的正确性和科学性。

The testees'previous mathematics knowledge and the problem's difficulty level have a major effect on sense of self-efficacy in mathematics learning, which ought to be taken into account in the testing .

被试的数学基础和测题的难度对数学学习自我效能感的影响很大，这两个因素也是在自我效能测量中必须要考虑的因素

On the basis of the mathematical models got by different measuring methods, a complete universal mathematical model was put forward by which different tappets lifts can be converted from one to another.

针对凸轮升程测量量具及方法不统一而造成升程转换困难及转换误差较大等问题，在研究凸轮升程各种测量方法数学模型的基础上，提出一个不同形式推杆升程相互转换的通用数学模型。

The problem with trying to argue that the male tendency to systemise suggested by Dr Baron-Cohen might lead to greater mathematical ability is that, in fact, girls and boys are equally good at maths prior to puberty.

Baron-Cohen博士所提出的男性由于更具系统性而在数学能力上占优的观点有一个问题，即事实上在青春期前女孩和男孩在数学方面是一样出色的。

In the paper, the simulation model of port plate/cylinder block frictional pair in which the lubricating film forms was established according to force balance equation and flow continuity equation with SIMULINK of MATLAB. The frictional pair includes of damp groove type continuous oil supply port plate /cylinder block frictional pair and semi-perimeter double oil groove type periodical oil supply port plate /cylinder block frictional pair.

本文根据配流副数学模型中的力平衡动态方程和流量连续方程，利用数学仿真软件MATLAB中的SIMULINK工具包分别对阻尼槽型连续供油配流副和半周槽双油腔间歇供油配流副建立了润滑膜形成的仿真模型，并对不同工况下的这两种配流副润滑膜的形成及变化规律进行动态仿真研究。

The results indicated that most students were dependent on the problem's surface structure for their sortings. Futhermore, an interaction effect was found between the student's grade and their achievement. As the grade level increase, instesad of using surface structure, high achievement students tended to sort problems according to their semantic structure. On the contrary, low achievement students became relied more and more on the surface structure of the problems while sorting.

另外，学童之年级及其数学成就对他们采用何种策略解题有交互影响；随年级的提升，高数学成就组学童倾向放弃弃表面特徵，而改较高层次的语意结构作为分类的基础；反之，五年级低成就组学童则变得更依赖问题的表面特徵作为分类的依据。
