In the paper, a technology of intellectualized fault diagnosis for DEDU in the ship was researched.

首先，分析了船舶柴油发电机故障诊断领域的各种诊断方法，系统研究了专家系统技术和故障树技术。

The dendrogram was obtained with Mega2 analysis. The analysis result was consistent with those from morphology.

运用Mega2软件进行的系统分析得到大戟属内6种植物的系统进化树。

Obviously, the combined dendrogram can reveal more difference among strains, and contain more phylogenetic information, so it reveal more detailed phylogenetic relationship among strains.

从综合的树状图能看出菌株间更大的差异，它所包含的系统发育信息更多，因而它所反映的系统发育关系更细致。

Then the failure probability of extinguishments system at initial stage of fire is concluded from fault tree analysis and the error propagation analysis of fault tree is made.

通过对系统故障树的分析，得到我国商业建筑火灾初期灭火失败概率的期望与方差，并对参数引起的误差进行系统误差传播分析。

On the other hand,it is necessary to cut web page for the purpose of customization and reduction in surfing costs of PDA and mobile consumers.A new method of web page cutting mobile device oriented is proposed.First,structuring HTML documents.Second,converting HTML to DOM tree based on DOM criterion.Third,cutting and re-constructing web page based on content block and link block.A prototype system has been developed by open source project named HTMLParser.

就以上问题，提出一种面向移动设备网页切割的解决方案：首先对半结构化的HTML文档进行结构化处理，接着基于DOM规范将HTML转化为DOM树并对其噪音清洗，然后对网页进行基于内容和基于链接的分块并对分块结果按照分层和用户定制的思想进行切割、重构，最后在开源项目HTMLParser基础上开发了原型系统并对系统执行效率和切割效果进行了评估。

First, the stations'timing process and the slot aligning are discussed. Second, the dissertation propose a resource request random access method based on feedback. The performances of this method are analyzed. Third, proceed from the considerations of the MAC protocol for the HFC system, a QOS-oriental scheduling algorithm for the MAC protocol based on dynamic TDMA is proposed. Simulation results show that the performance of this algorithm is better than that of the first come first service. Forth, two contention resolution algorithms ----p-persistent CRA and tree CRA, which are usually adopted in the HFC system, are summarized. The delay and characteristic are compared. At last, the dissertation introduces the function implementation of the MAC layer based on COM21 UPSTREAMS.

首先，讨论了基站的同步进程和时隙同步的实现；然后，本文提出了一种带反馈模块的资源申请信号随机接入方法，并对其进行性能分析；然后，从HFC系统的MAC协议出发，提出了一种用于基于动态TDMA技术的MAC协议的业务安排算法，计算机仿真结果表明其性能优于先到先服务法的性能；然后概述了常用于HFC系统的两种冲突解决算法——p-坚持冲突解决算法和树型冲突解决算法，比较两者的时延性能与特征；最后，介绍了基于COM21 UPSTREAMS协议的MAC层功能实现，给出了硬件框图和照片。

This paper studies the assessment of EPSS systematic, and introduces the current information performance evaluation in various ways, especially analyzes the application of decision tree technology in the evaluation of education. Finally, the article discussed the background and circumstances of revise of EPSS evaluation rubrics, and hopes to do some contribution to the continuous development of EPSS assessment system.

本文主要研究了EPSS系统的评价部分，介绍了目前信息化绩效评价中各种方法，重点分析了决策树技术在教育评价中的应用，最后文章讨论了EPSS评价量规修订的背景和情况，希望能对EPSS评价系统的不断发展有所贡献。

The first parsimonious analysis yielded numerous most parsimonious trees of 275 steps, and then 82 most parsimonious trees with 40.729 steps length were produced by reweighting characters using maximum values of rescaled consistency, which remained stable after the second reweighting.

属为外类群，选取包括花粉和染色体性状在内的47个广义的形态学性状进行了分支分类系统发育分析，同时以表征分类的方法构建了距离树辅助分析，首次对世界分布的菝葜科各属间及属内的系统发育关系作了探讨。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
