不重合

A superposition cut is used to describe a cross section of a part by revolving it around an axis of revolution and placing it on the views on the axis.

在不影响图形清晰的条件下，断面也可按投影关系画在视图内，画在视图内的断面图称为重合断面图。

Researches show that the drive force characteristics of the electric tractor drive system based on series DC motor is close the ideal characteristics, the curves are concave, low speed with constant power, and high speed with constant torque; the electric tractor has large working speed under different shifts, but the extensive coincidence speed shows that the variable ratio of the gear is unreasonable; the maximum climbable gradient of this electric tractor is more than 30%, and does not need frequent shift when working for its extensive climbable gradient; there are many influence factors of continuous working time, which the more obvious factors are working speed and working load, the working time increases with the increase of the working speed and working load.2. Simulation researches on the drive characteristic of the electric tractor.

研究结果表明：基于串励直流电动机(来源：ABC21论文网www.abclunwen.com)的电动拖拉机电驱动系统的驱动力特性场接近理想驱动力特性场，其各挡下的驱动力特性是一组下凹的曲线，低速恒转矩，高速恒功率；同一行驶速度下所对应高挡驱动力大于低挡驱动力，这是由电机的调速特性决定的；电动拖拉机各个挡位下具有较广的稳定作业速度范围，但是各个挡位之间速度重合的范围较多，说明所用变速箱变速比与电动机匹配不合理；电动拖拉机最大爬坡度达到30%以上，并且各挡爬坡度变化范围较广，作业过程中不需要频繁换挡；影响电动拖拉机连续作业时间的因素较多，其中作业行驶速度和作业负荷影响最为明显，作业负荷越大，连续作业时间就越短，作业速度越快，连续作业时间就越短。2、电动拖拉机驱动特性仿真研究。

At first, we establish some new KKM type theorems involving admissible set-valued mappings and the set-valued mapping with compactly local intersection property in FC-spaces. As applications, some new coincidence theorems and fixed point theorems are proved in FC-spaces.

首先，在FC-空间中得到了涉及容许类集值映射和具有紧局部交性质的更为一般的KKM 型定理，作为应用，在FC-空间中证明了一些新的重合点定理和不动点定理。

If the centroidal axis is not colinear with the element x-axis, applied

如果质心和剪切中心不是重合的，施加的剪切

The error is bringed because the post-vertex of the eyeglasses is not superposition with the post-focus of the objective of the dioptometer.

由于被测镜片的后表面曲率各不相同，致使镜片后顶点与焦度计物镜后焦点不相重合，因而造成测量误差。

The key idea of Incompleteness Theorem lies in the proof that aclass of strong subsystem of mathematics is incomplete.

真和可证的区别有两层意思：一是真和可证的命题集不是重合的，二是在形式算术中真不能作谓词而可证可以作谓词。

A section theorem, a minimax inequality and a generalized fixed point theorem where the underlying space is a product space of two topological vector space s, are given.

给出了两个拓扑向量空间的乘积空间上截口定理，极小极大不等式及一个推广的不动点定理。指出这3个形式不同的结果与Tychonov不动点定理是相互蕴含的。并且用截口定理直接证明了多值映射的一个重合定理

These vertices, however, may not be distinct, as in the case where the endpoints may coincide.

但这两个顶点不一定是不相同的，譬如在两个端点重合时的情况。

Do fill gaps in the "operation" could be first ribbon in the "loophole" in the region cut off, and then cut the ribbons,"weld" together,"welding" as long as the first band at the interface at both ends of alignment and It is a little overlap, and then use transparent tape to the inside of the two ribbons together interface adhesion; if afraid of sticky tape is not strong, you can use thin wire in the ribbon at the joint and under the edge of the seam on the edge of a needle (This does not affect the normal work of the ribbon, ribbon work, after all, the main use of the middle region).

在做补漏&手术&时，可以先将色带中有&漏洞&的区域剪掉，然后再将剪断的色带&焊接&起来，&焊接&时只要先把色带两端的接口对齐并稍微有一点重合，然后使用透明胶带将色带内侧的两个接口粘连在一起；要是怕胶带粘性不强的话，可以用细线在色带接头处的上边缘和下边缘各缝上一针(这样不影响色带正常工作的，毕竟色带工作时主要使用中间的区域)。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
