In the proposed device to remedy the defect that overhigh withstand voltage of thyristors used in converter are needed due to the overhigh DC link voltage, a method to control DC link voltage is put forward, that is, a special control logic for full-controllable switching elements is designed to make them equivalent to half-controllable switching elements which are naturally turned on and turned off by triggering, then connecting such a half-controllable switching element in series with DC link the defect of overhigh DC link voltage is effectively solved.

为了克服该装置直流母线电压过高，因而对逆变器开关管耐压要求过高的缺点，提出一种对直流母线电压进行控制的方法。对全控型开关器件设计一种特殊的控制逻辑，使其等效为一个自然导通、触发关断的半控型开关器件，将该半控型开关串联在直流母线上，有效解决了直流母线电压过高的问题。

The metaphor of a flat world is worked relentlessly throughout this overlong book, but it is not its incessant repetition that is most troublesome. It is Friedman's failure to recognize that in many ways, some of them not difficult to observe, the world is becoming distinctly less flat.

In the same way, the reason why the British politicians now in England find it difficult to govern Ireland and India, is because modern Englishmen today do not know that it was not British democracy, the British Constitution or Parliamentarism, but the British or English civilization with the "gentleman" and its ideal; in short, that it was not the British mob, but the British or English gentleman who built up the great British Empire of today. But that is neither here nor there.

同样，不列颠"无名战士"，新近葬入英国西敏寺，驱走恶魔，封建德国狂怒之条顿人，目今英国之不列颠政客，之所以觉爱尔兰及印度难治者，盖因今日现代英国人不知，今日大不列颠帝国之所以成者，既非不列颠之民主、亦非不列颠之政体或议会制度，而乃不列颠或英格兰文明蕴有"温良"及其理想之故也；简言之，今日大不列颠帝国之所以成者，非不列颠群氓之功，而乃不列颠或英格兰温良秉性之士之功也。

He has some evidence that adding parsimony at the end of evolutionary procedure -- that is, first let the system find a solution that kind of works and then start paring it down -- is a better way to evolve succinct equations.

他有些证据可证明，在进化过程的结尾加入简约性——即，先让系统找到一个可行的解决方案，然后再开始把这一方案简化——更有利于演化出简洁方程。

We firmly believe that a Japan that is unable to question its past is unable to uphold world peace, and a Japan that denies its war guilt cannot claim to be civilized!

On the base of applied tech. and system structure, the key tech. are expressed in detail. It includes:Knowledge representation technology: it is described in two stages by "Depictive frame + Rule group"."Depictive frame" is used to reflect the factors concerning question field."Rule group" reflects the son-question in question field; knowledge management system: it is made up of knowledge-base editing component, factor classifying component, knowledge inspecting component and extractive knowledge component; uncertainty reasoning adopt method of elicitation search strategy and data drive controlled by member knowledge. It take reliability of compound proof at first. That can resolve the matching contradiction. Reasoning explanation introduce pre-text and followed method of resolving path. Knowledge discovery component take SLIQ as basic arithmetic. It provides classification model in two stage forms which aim at training suit. That is decision tree and productive rule.

在确定应用技术与系统结构的基础上，重点阐述了本文的核心技术，这包括：知识表示技术，采用"描述框架+规则组"的层次结构，"描述框架"用于描述问题域所涉及的因素，"规则组"反映问题域内的子问题；知识管理系统，由知识库编辑构件、因素分类构件、知识检测构件和知识求精构件组成；不确定性推理机采用启发式搜索策略，元知识控制的数据驱动，以复合证据可信度优先作为匹配冲突消解的策略，推理解释采用预置文本与求解路径追踪的方法；知识发现，采用SLIQ快速可伸缩算法，分类模型用判定树与产生式规则两种形式描述。

The most dangerous thing, I think, for children on television is the commercialism, and I get really angry about television programs that are produced, which are really produced not because they're interesting television programs but because they're part of a big marketing exercise, so that at the same time the shops will be flooded with rubbers and pencils and bags and pencil cases and things like this and there's a tremendous pressure on children to go out and buy those things, and I think that is a very dangerous thing indeed.

对于看电视的孩子来说，最危险的事，我想，是广告。我对某些电视节目很恼火，它们被制作出来并不是因为节目本身好玩，而是它们本来是市场活动的一部分。所以与此同时，商店挤满了橡皮擦、铅笔、袋子和铅笔盒，诸如此类的东西。小孩一出去就面临巨大的压力，想去买这些东西。所以我想这确实是一个危险。
