In this paper, an indexing scheme, inspired by the Dewey decimal notation, is proposed for simplifying the implementation of the search algorithm.

本篇文章首先介绍一种索引架构，可以简化上述搜索演算法的施行。这种索引架构，主要是起因於杜威的十进位符号观念。

JavaScript Object Notation format which can simplify its implementation task dramatically instead of using an XML document oriented style.

JavaScript对象符号）格式，从而简化其执行任务，极大地而不是使用XML文档化的风格。

By the analysis of dive and horizontal plane nonlinear model, the catastrophe model on de dive plane is deduced, and catastrophe stability is analysized. In the horizontal plane, simplified equation is gained by center manifold theory, then draws the conclusion that the stability of limit circle arises from critical point is relate to small difference of move point and critical point.

通过对潜艇垂直面和水平面非线性运动模型进行分析，导出垂直面运动的突变控制模型，并进行了突变稳定性分析；在水平面运动的非线性分析中，通过中心流形定理简化方程，得出临界点处极限环的稳定性与微差占的符号有关的结论，这样在无法或很难得到李亚普诺夫函数的情况下，可以通过这种方法判别临界点的稳定性。

Firstly, the Signal Noise Ratio characteristic of matched filter despread symbol and the distribution of coherent phase estimation error are derived. Secondly, the exact integration formula of BER for fading channel is presented, moreover, by using the Maclaurin series expansion of MPSK conditional Symbol Error Rate, the simplified BER approximations for BPSK and QPSK are derived over AWGN, Nakagami-m fading and Rayleigh fading channel.

首先推导了匹配滤波解扩符号的信噪比特性和相干相位估计误差的分布；然后给出了衰落信道中误比特率的精确积分式，并利用MPSK条件误符号率的麦克劳林级数形式，推导了AWGN，Nakagami-m衰落和瑞利衰落信道中BPSK，QPSK误比特率的简化逼近式。

In addition to the standard syllabic grid, there are optionalsigns used to clarify the spelling of a word.

除了这些标准的音节符号，还有一些辅助的符号被用来简化单词的拼写。

These eventually evolved into the basic symbols for neumatic notation, the virgawhich indicates a higher note and still looked the acutus from which it came; and the punctumwhich indicates a lower note and , as the names suggests, reduced the gravis symbol to a point.

这些标识很明显是纽姆谱中最基本的符号，virga或者rod，表示一个更高的音符，这个符号的形状仍然和actus，/很相像，而punctum这个代表更低音符的标识，从标识名称上就能表明它是简化了的gravis，\符号。

ER semantics contributes to correcting segmentation ambiguity and partially solving unlogged words problem at segmentation stage, to generating semantic consistent grammar trees and reducing parsing ambiguity at parsing stage, to simplifying semantic process at semantic process stage.

为了更好地了解用户使用中文进行数据库查询的句式以及从中抽取一定的语法规则，我们进行了用户使用受限汉语书写数据库查询语句的调查和分析，然后在此基础上我们设计了一种新的文法GWERSC，其非终结符集合不仅采用了现代汉语的文法符号，如名词短语、助词等，同时还采用了与数据库概念紧密相关的实体、属性、联系等语义符号，这样就把现代汉语尤其是受限汉语的知识和数据库知识紧密结合起来，既有利于文法分析又简化了语义处理。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
