The main contents of the paper are as follows : 1. According to the characteristics of low embankment, this paper analyzes the mechanism and rule of traffic load acting on the subgrade, and then abbreviates describing methods of the vehicle load in math. 根据低路堤的工程特点,从车辆对路基影响方面,分析交通荷载的作用机理及变化规律,进行交通荷载的简化描述。
It is discussed prestressed cable-truss optimization design with its design variables including cross-sectional size and cable pretension force; and constraint conditions of the two stages of load are considered, a relevant math model is founded, and a new mothed of its solution is put forward. 就设计变量包括索力值的预应力索-桁架截面尺寸优化设计问题,考虑了荷载两阶段的约束条件,建立了相应的数学模型,提出了新的求解方法。
Chapter two discusses the principle and the process of the realization for Math Function and the unitive interface of Math Function load. It also discusses the creation of Math Function and the realization process of the function. 第二章论述了数学函数及数学函数加载的统一接口的实现的原理及其实现过程,以及数学函数控件的生成和功能的实现过程。
An automated method for measuring load coaxiality of universal testing machine was presented in two aspects : basic hypothesis, math modeling for calculating and processing. 叙述力同轴度自动检测技术:基本假设、计算模型的建立及数据处理方法。
Effectively reduce the load of students, to effectively reduce the burden on teachers, to improve mathematics learning, to enhance the quality of math, the students learn their own initiative to improve student math literacy, education, to improve the quality of teaching. 切实减轻学生的课业负担,切实减轻教师的工作负担,提高学生学习数学的兴趣,提升数学素质,把学习主动权交给学生自己,提高学生数学素养,提高教育教学质量。
