测试函数

Through the source code audit such as RATS software can find the flaw information of level of partial source code, but after all the majority that software of source code audit searchs spills over for the existence buffer such as Strcpymemcpy the C function that involuntary discharge of urine has, the measure that adopts audit source code so will undertake flaw is dug is coefficient of a possibility very small leak digs a technology, and the flaw that although also can find a few software,checks in the light of the black box of software, but possibility coefficient also is met lesser, a few undertakes flaw is dug idea that are in abroad already slowly promotion writes black box to check code for oneself, the module of a certain function that is aimed at system or software next undertakes modular flaw digs a technology.

通过RATS等源代码审计软件可以找到部分源代码级别的漏洞信息，但是究竟源代码审计软件寻找的多数为strcpymemcpy等存在缓冲区溢出遗患的C函数，所以通过审计源代码的办法来进行漏洞挖掘是一个可能性系数很小的漏洞挖掘技术，而针对软件的黑盒子测试虽然也能找到一些软件的漏洞，但可能性系数也会较小，在国外的一些进行漏洞挖掘的办法已经慢慢的提升为自己写黑盒子测试代码，然后针对系统或软件的某个功能模块进行模块化的漏洞挖掘技术。

Firstly, with Gaussianizing filter being defined explicitly, a practical method on filtering performance evaluation is given. Secondly, two typical Gaussianizing filters are studied. One is called the U-filter, based on the probability density function and its derivate. The other is called the G-filter, based on the cumulative distribution function and its inverse. After implementation, mechanisms and performances of each filter are contrastively discussed, an example with lake trial is illustrated.

In a nutshell, named function expressions are useful for one thing only - descriptive function names in debuggers and profilers .

简而言之，有名函数表达式只对一件工作有用，在调试器和性能测试器中描述函数的名称。

The abnormal values and pseudo-modes existed in the measured FRF can usually introduce errors into the result of structure modification, for the purpose of eliminating these errors and carrying on dynamic modification of complex structures in a large scale, the fictitious force modification method, which is based on constructed FRF, is proposed and it can restrain the influences of test errors on modification results remarkably. Furthermore, it is more convenient and precise.

实测频响函数中存在异常值或虚假模态对结构修改会产生较大的误差，为消除其影响，并进行复杂结构的动力大修改，本文还提出了基于构造频响函数的拟力修改法，这种方法能显著地抑制测试误差对修改结果的影响，且处理方便、精度高。

The run-time function/functor is typically a test that is called upon to resolve ambiguity in the grammar.

运行时的函数/函数对象通常是用于解决语法二义性的一个测试。

Combining the testing accuracy of different kernel functions, an optimal kernel function is obtained to solve this problem.

Through Hilbert transform, a signal's plane trace can be get. There are two frequencies in the tested signal, so the signal's plane trace may be looked as the track of the out pole's end when two poles rotate around parallel axles. Using the knowledge of motion synthesis in theory mechanics, a formula to describing the change of plane trace's step length and angle for two-frequency be get. So we may prolongate the tested signal's plane trace from the echo's initial arriving moment, and get a certain length of the signal's prolongation.

通过Hilbert变换可得到测试信号的平面迹线，测试信号中只含有两个频率成分，视为双频信号，双频信号的平面迹线相当于两连杆绕平行轴转动时外杆杆端迹线，利用理论力学中运动合成和瞬心知识，推导出双频信号平面迹线步长平方满足余弦线性复合函数，而迹线转角可视为线性变化，据此可对回波到来之前的测试信号平面迹线作延长，得到一定长度的信号延展段，信号延展段与实测段作差可得到一次、二次回波的第一个波峰值。
