主操作

T he operating platform is located in front of the headstock and can be elevated independent of it.

And such code answer using is efficiency is the poorest, when because become,you should be revised, you must revise the place that all and such Sql operates at the same time, of course, the original poster can say, you can compress identical Sql operation to arrive in method of a help, but such word, and founded a special DAO to was not distinguished!

而这样的代码复用是效率最差的吧，因为当你要修改的时候，你必须同时修改所有如此sql操作的地方，当然，楼主可以说，你可以压缩相同的sql操作到一个帮助方法中，但是这样的话，和创建1个专门的DAO不就没区别了么！

Then the reconstructed data are analyzed by multiple statistical indexes such as T2 or SPE to determine if the supervised process exceeds the normal control limits. If fault occurs, then the supervising program will alarm to prompt that the process has abnormal states. Because it is hard to get the inverse mapping from the kernel space to the original space after the original data are nonlinear mapped by the KPCA method, hence it is difficult to diagnose how the fault happened.

该方法首先构造系统正常时的核主元模型，然后将新的数据映射到该核主元模型，对数据进行重构，重构的数据用多元统计指标T2或SPE判断监测过程是否超出了正常的控制限，若有故障发生，则监测程序将给于警告，提示过程出现了异常操作状况。

This Memory Resident Database Supply these features: Definition of data(table、index、queue et), operation of data; synchronization of data: Data synchronous abilty is pivotal function to distributed DBMS(synchronization of static data, dynamic synchronization between master processor and slave processor); database power-on; Saving and Loading of database etc.

根据系统设计的要求该内存数据库提供以下功能：数据定义，数据操作（数据的插入、删除、修改、查询）；数据的同步机制：数据的同步功能是数据库系统保证分布、备份数据系统一致性的关键(各模块之间的静态数据同步、主备MP大量数据的动态数据同步、MP间动态数据同步)，其中本文主要介绍了主备MP的动态数据同步；数据库系统并发性控制。

The model of principal components is built up by applying a method of principal component analysis and by extracting the principal character of process variable to condense process data of multi-variables in a process of chemical polymeric production.

对聚合生产过程中的操作变量进行主元分析，提取过程变量的主要特徵，建立主元模型，可实现对多变量过程数据的压缩。

From the point of view of operation and control,the margin of air flow rate in FCCU regenerator was calculated by dynamic optimization.

从生产操作和闭环控制的角度，用动态优化的方法对再生器的主风裕量进行了计算，指出过程动态特性对主风设计裕量的选取有着很大影响。

The examination falls into two parts: the written test and the operation test. The written test is to check one's basic electric knowledge, which includes electric control theories, installation standards, etc. The operation test is a bit difficulty. Firstly, you have to connect several major loops and control loops appointed by the examiner within limited time. If you do right, the electricity is connected, the bell rings and the light turns on, then you will pass the test; but if it explodes and emits smoke, then you will not only get zero score but be scolded. Life is not a game, and one should never pretend to know things that he does not know.

考试分笔试和操作二项，笔试的内容都是最基本的电工知识，电气控制原理，电气安装规范等等，而考操作就有难度了，首先要你在规定的时间里接好考官指定几的主回路和控制回路，接对了，通上电，灯亮铃响顺利过关；若是爆炸冒烟，那不仅没分还要挨骂，生命不可儿戏，不懂不能装懂。

The proposed inverter has a new auxiliary resonant commutation cell. It provides that all main switching power devices in the soft-switching inverter operate at zero-voltage-switching turned-on and the auxiliary switches operate at zero-current-switching turned-off. In addition, this thesis presents an improved control scheme to minimize the operation of auxiliary resonant circuit for efficiency improvement.

所研制之柔切式数位变流器，系利用新型辅助谐振单元，使主功率开关操作於零电压切换，辅助开关操作於零电流切换，在此也提出改善之控制方案，以避免多余的辅助开关切换，因此能有效降低谐振电流所造成的额外导通损失，以提升系统之效率。

The image forming device also includes a pressing body which is provided on the main frame and is slidable in a direction along a straight line orthogonal to a rotational center shaft of the electrostatic latent image carrier and a rotational center shaft of the developer carrier, and an operating unit which operates the pressing body to press a bottom surface of the developing unit by sliding the pressing body in a direction of the straight line and to hold the pressing body so that the developer carrier is maintained under a state making contact with the electrostatic latent image carrier.

该成像设备还包括：一个按压机构，该机构设置在该主框架上，并在按压方向上沿着这样直线的方向滑动，其中该直线垂直于静电潜象载体的旋转中心轴和显影剂载体的旋转中心轴；以及一个操作装置，该操作装置通过在直线的方向上滑动该按压主体以按压显影单元的底面，并保持该按压主体，从而该显影剂载体保持在与静电潜象载体接触的状态。

Thoracoabdominal aortic aneurysm is a hazardous vascular disease,of which the operation is complex and difficult,and associated with high morbidity and mortality rate.

胸腹主动脉瘤是一种凶险的血管疾病，手术操作复杂、难度大，手术病死率和并发症发生率高，血管外科医师们为提高手术的治疗效果在不断探索新的手术方法，本文简要介绍胸腹主动脉瘤手术方法的变迁，包括分型，手术方法，效果及优缺点。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
