本文根据对塔里木河的实际调查资料，分别计算了上、下游典型样地的物种多样性指数、丰富度和均匀度指数，对塔里木河上、下游地区的天然植被的群落特征进行了对比分析。

According to the signal characteristics, three candidates algorithms, threshold judgment through Lenner Filter Banks, Notch adaptive filter and VIFD(Variance of Instaneous Frequency Detector), and complex correlation detection, have been selected and tested. To maximize the accuracy and fulfill other parametric requirements of the system, simulation models are established on these selected algorithms, and data analysis work is done basing upon vast sampling.

根据信号的特点，选取了Lenner滤波器阈值判断、Notch自适应滤波器和VIFD联合判断以及复相关检测三种算法，建立仿真模型对三种信号检测算法分别进行仿真以及用实际的海试数据来选出一个比较合适的算法，保证标定系统的标定精度，满足指标的要求。

The main ideas are as follows. 1. To estimate instantaneous speed and angle position when angular sampling can not used, some methods have been analyzed firstly.

为此，本文分别采用计算阶比分析、广义多相干分析和径向基函数网络等方法，来解决旋转机械变速过程中的信号预处理、特征提取和烈度监测等问题。

The relationships of signal-to-noise ratio of sampled signal, analog filter before analog-to-digital converter and sampling rate have been discussed, the results of the discussion have instructiveness for the design of digital receivers.

该文讨论采样后信噪比与模数转换器前的模拟滤波器以及采样率之间的关系，所得结论对数字接收系统设计有指导意义。

The digital algorithms of integral and discrete wavelet transform are presented for purpose of electric power system protection, based on the analysis of wavelet transform for sampled digital signals under the Shannon sampling theorem.

从电力系统继电保护应用的角度，结合香农采样定理，深入探讨了连续信号和离散信号的小波变换的关系，给出了离散信号的积分小波变换和离散小波变换的数字计算方法。从理论上研究了信号小波变换的误差与尺度函数和小波函数的关系。

In the second place, this paper uses the financial data reported by China's private listed companies and statistical analysis skills to test the theories and hypotheses. The research collects all required data from 2000 to 2002, examines the profit ability, the gain ability, the repay ability, and the cost control ability for all sampling listed companies by using Paired-Samples T test in the quantitative analysis section. The results show that these listed companies'profit decreases, income increases, repay ability enhances after the companies go public. Finally the paper takes the non-operating expenses as the illustrating index for the cost control capability of the companies to demonstrate that there is an obvious increase of non-operating expenses after getting great amount of money in IPO, in this sense it can be stated that there is the intendancy of low capital utility rate in private companies.

研究选用了描述性统计分析方法对样本企业IPO前后时段的财务指标进行了对比考查，并运用配对样本t检验方法进行了显著性检验，研究结果表明民营企业在IPO前后的盈利水平总体上是显著下降的；同时研究也显示虽然获利水平出现了小幅上升，但这是由于企业通过IPO融资增加了投资规模导致的；企业的偿债能力在IPO之后有明显的好转；研究最后以营业外支出作为企业成本控制能力的解释指标，发现企业在IPO上市融得大量资金后对主营业务以外的支出有明显的增多，可以判断民营企业存在资本利用效率低下的现象。
