Drilling of the jugular tuberculum is the key step for access to the central clival depression. Partial mastoidectomy can result in a significant increase in surgical freedom, but only a modest increase in the exposure of the central clival depression. Removal of total condyle and resection of the lateral mass of C1 could not increase the surgical freedom and exposure of the central clival depression.

磨除颈静脉结节为经FLA入路显露斜坡中央凹陷区的关键步骤；部分乳突切除可进一步改善操作空间，但未能显著增加斜坡中央凹陷区的显露；全切枕髁和侧块不能显著增加斜坡中央凹陷区的显露和操作空间。

On Friday 10 August, in Europe and in the United States, an incredible thing happened: in 24 hours banks became too mistrustful of each other to do any mutual lending, forcing the central banks to step in massively.

8月10日星期五，在欧洲和美国，发生了一件不可思议的事：在24小时内，银行之间完全不信任，不做任何相互贷款的业务，迫使中央银行严正介入。

Establish the steady-state and transient model using the three hydrodynamics equations (Continuity equation, Momentum equation and Energy equation). By comparing different state equation, it selects the BWRS state equation which is considered the most accurate state equation in current natural gas measurement. It calculates compression factor, density and other Thermal parameters based on BWRS state equation. In Numerical solution of the steady-state and transient model, compression factor, friction coefficient and all the other Thermal parameters are recalculated in each small time step to reduce the numerical calculation error.

在稳态模型的建立上，利用流体力学三大方程(连续性方程、运动方程和能量方程)，通过比较不同的状态方程选用了目前被认为最精确的用于天然气计量的BWRS状态方程，并以此方程为基础进行压缩因子、密度等热物性参数的计算；在稳态模型的求解上，选用容易计算，精度较高的标准型龙格—库塔(Runge-Kutta)法进行数值求解，并且在迭代过程的每一小步都重新计算燃气的压缩因子，摩阻系数等所有的计算参数，以减少数值计算的误差。

Finally, the main job is looked back main job and ILBS's advantage and foreground of development are summarized in the paper. The two problems are pointed in the paper that will be improved. The first problem is that currently only we consider every node is single computer. The second problem is that the technology is relation with development of several mainstream's subject in which user submitting job will be classified by many dimension or arithmetic of every step is evaluated. The two development of cluster are together with the mainstream's subject.

最后，全面回顾了论文的主要工作，ILBS优点和发展前景；同时也指出ILBS系统中有两个待完善的地方，一是资源获取模块中，当前只考虑了节点为单机的情况，二是用户提交的问题从多个维度进行分类、以及各环节算法的评价等方面的技术与当前的几个主流学科发展息息相关，集群在这些方面的进步离不开与它相关的学科的发展。

The step motor can receive digital signal directly and has the ability to response outer environment immediately and has no accumulation error, which often is used in driving system. In this driving system, open-loop control system is composed of stepping motor, which can satisfy the demand not only for control precision but also for the target of economic and practicality. On this basis , the analysis of stepping motor in power calculating and style selecting is also given.

由于步进电机能够直接接收数字量，响应速度快而且工作可靠并无累积误差，常用作数字控制系统驱动机构的动力元件，因此，在驱动装置中采用由步进电机构成的开环控制方式，这种方式既能满足控制精度的要求，又能达到经济性、实用化目的，在此基础上，对步进电机的功率计一算及选型问题经行了分析。

It can read one, two or three input sequences in either of FASTA, GENBANK or EMBL format, then it runs the external program BLASTN or MegaBlast to do the comparison between paired sequences in background. If the results already exist, it can skip that step and read the output file directly. Then the dynamic display of the results will show in the canvas of the main window.

它可以接受FASTA、GenBank或EMBL等多种输入数据格式，自动在后台调用BLAST包中的核酸序列比较软件进行比较操作，然后对结果进行分析和处理，过滤掉冗余的信息，最终将结果以动态的图形化方式显示出来。

Step one: press Win + Pause / Break key combination to open "System Properties", switch to the "Advanced" tab, click the "Environment Variables" button, in which the "system variables" column, click on the "new" button in the "variable name" inside input "Devmgr_show_Nonpresent_Devices", in "Variable Value" enter "1", three "OK" after the withdrawal from the "System Properties" window

第一步：按下Win+Pause/Break组合键打开"系统属性"，切换到"高级"选项卡，点击"环境变量"按钮，在其中的"系统变量"栏中，点击"新建"按钮，在"变量名"里面输入" Devmgr_show_Nonpresent_Devices"，在"变量值"输入"1"，三次"确定"后退出"系统属性"窗口

A microcomputer is used to communicate with the controller of electron probe to control the spectrometers and the sample stages as well as the scalers. Data of X-ray intensity are acquisited when the sample stages are scanning in a certain step and time period. X-ray images were formed and shown in colors or in 3 dimensions, and have no distortion at low magnification. Hidden zonate phenomena of a picrite were found.

摘 要：用微型计算机与电子探针控制机通讯，实现对各道波谱仪和样品台的实时控制，以及对各道定标器的数据采集；在选定的样品区域上设定采样步长和时间，边移动样品台边采集各道X射线强度；用伪彩色、三维视图和内插放大等方式显示图像，解决了低倍X射线像失真问题，观察到了辉石的隐环带等现象。

In old Roman law, another step was absolutely required; it was necessary for the promisee, after the agreement had been made, to sum up all its terms in a solemn interrogation; and it was of this interrogation, of course, and of the assent to it, that proof had to be given at the trial —— not of the promise, which was not in itself binding.

在古罗马法中，另一个步骤是绝对需要的，即允约人在达到合意后必须把所有条件综合在一个庄严的问句中；并且，在审判时，必须提出的证据，就是这个问句以及对这问句的同意——而不是允约，允约本身是没有拘束力的。

This result answers, in an average sense, the question in networked control system of how large quantization error is allowed in a step tracking with a given tracking error energy level.

这个结果回答了基于网络的控制系统中的一个基本问题：控制信号的量化误差是如何影响系统的跟踪性能的？

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
