This thesis is composed of two sections in which we discuss generalized spectral density test of conditional autoregressive heteroscedasticity for threshold autoregressive model.

本文分两节对门限自回归模型中自回归条件异方差的广义谱密度检验进行了讨论。

Adopt the generalized maximum likelihood radio test based on the Neyman-Pearson algorithm, to study two unresolved Rayleigh targets. And deduced the detection statistic which is chi-square random variable, which only need to know the conditional probability density functions of echo's measured amplitude, in-phase and quadrature of monopulse radio, but the signal-to-noise radio and the direction-off-arrival of any signal are unnecessary.

采用基于涅曼-皮尔逊准则的广义似然比检测，对不可分辨的两个瑞利目标进行了研究，推出了服从χ2分布的检验统计量，此方法只需要知道目标回波信号测量幅值的条件概率密度函数、单脉冲和差比值的同相和正交部分，而不需要任一目标信号的信噪比和DOA的先验知识。

The value of a conditional expression is defined as follows: If the effective boolean value of the test expression is true, the value of the then-expression is returned.

一个条件表达式的值定义如下：如果测试表达式的有效布尔值为true，则返回then表达式的值。

If the effective value of the test expression is true, the conditional expression ignores any dynamic errors encountered in the else-expression.

如果测试表达式的有效值为true，条件表达式忽略任何else表达式中遇到的动态错误。

If you want to use a non-boolean in a boolean test, such as if, you must first convert it to a boolean value using a conditional expression, such as ifa !

若想在一次布尔测试中使用一个非布尔值——比如在if里，那么首先必须用一个条件表达式将其转换成一个布尔值，例如ifa！

TESTSET Boolean test, with conditional jump and assignment

布尔测试，带条件跳转和赋值

Affixes are limited in number in a language, and are generally classified into three subtypes, namely, prefix, suffix, and infix, depending on their position with reference to the root or stem of the word.

语言中词缀的数量总是有限的，根据它们跟词根或词干的相对位置，一般可以把词缀分外三小类：前缀，后缀和中缀。
