零函数

But this treatment introduces two new parameters ku and kd, and the values of the anomalous magnetic moment need further studying.

当把夸克看成有结构的，即夸克存在不恒为一的结构函数，并且反常磁矩不再为零，这样便引入了两个新参数一夸克的反常磁矩，在正常合理的参数下计算结果与实验的符合表明有所改进，不过参数的合适选择看来仍起关键作用。

A differential difference type adaptive law and an adaptive iterative learning controller are constructed to ensure the asymptotic convergence of tracking errors in the sense of square error norm on the finite interval, by introducing a Lyapunov-like function, a sufficient condition of the convergence of the method is given.

通过引入微分－差分自适应学习律，设计了一种自适应控制策略，使得跟踪误差在一个有限区间上的积分渐近收敛于零；通过构造Lyapunov-like函数，给出了闭环系统收敛的一个充分条件。

The reason that zero can not be divisor, is right?Feng XinkongIn the eighth book of six-year primary school's teaching in nine-year compulsory educationmaterials, it states that "zero can not be divisor". But we can find that the formula, a=cq, checking the dividing exactly , is same as the form of direction proportion function, y=kx; the formula of checking the dividing not exactly, a=cq+r, is same as the form of simple function.

在九年义务教育六年制小学教科书《数学》第八册中规定"零不能作除数"，但是当我们学习了正比例函数和一次函数之后就会发现，验算能整除的除法的关系式a=cq和正比例函数y=kx的表示形式相同；验算有余数除法的关系式a=cq+r与一次函数的关系式y=kx+b的表示形式相同。

In the new method for two-dimensional problems the line integrals onboundary elements are converted into the evaluation of potentialfunctions at the ends of these elements.For three-dimensional cases,thesurface integrals on the usual boundary elements are transformed,through an application of Stokes'theorem,into line integrals on thebounding contours of these elements.

边界轮廓法是刚刚出现的一种新型的边界元法，该方法的核心是利用边界积分方程被积函数散度为零的特性，对二维问题，原积分方程中沿边界单元的线积分被化为单元两端点势函数之差计算，对三维问题，将边界单元上的面积分转变为沿单元轮廓的线积分，它是一种十分简便有效的边界元新技术。

This region of support values shape function is shape function is not zero in the region ...

这种数值形函数的支撑域是指形函数不为零的区域，。。。

This theorem states that the sum of the symmetric logic variables constitutes a level-0 kernel of the symmetric logic function.

该定理表明，对称逻辑函数的对称逻辑变量之和恰好构成了该逻辑函数的一个零级核。

The face contour is represented by zero level set function and approached by evolution of the level set function.

此算法使用零水平集函数对人脸轮廓进行表示，通过水平集函数的演化对人脸轮廓进行逼近。

In the computation of parameters of the microstrip antennas by MPIE,the inability to determine exactly the singularities of the dyadic and scalar Greens functions in space domain at the zero distance brings the unexactness to the whole calculation of parameters of the microstrip antennas.

在采用MPIE方程计算微带天线的参数时，由于无法精确确定零距离处的空间域并矢Green函数和标量Green函数的奇异值，对微带天线的整个计算结果的精确度产生了不利影响。

This paper presents several control methods for BLDC motor, and describes their fundamental principles ,advantages and disadvantages in brief. The method of speed-independent function,based on a new flux linkage function,is explained in detail. This method makes it possible to detect the rotor position over a wide speed range from near zero to high speed.

本文介绍了几种无位置传感器无刷直流电动机的转子位置检测方法，并对它们的基本原理，优缺点作了简单的说明，详细地阐述了基于一种新磁链函数之上的与速度无关的位置函数控制方法，利用这种方法从零转速到高转速的宽速度范围内能检测到转子位置。
