This paper deals with the partial capacitance calculation of the high voltage transmission line for the neutral beam injectors.

该文研究了中性束注入系统中高压传输线部分电容的求解问题；根据传输线多层同轴导电壳的结构特点，利用多重镜像法确定与平行导线相应的一系列的镜像线电荷，求解的问题变为由一系列平行线电荷构成的电场问题，传输线的部分电容则通过各导体间的电位系数来求得；这一方法避免了直接求解的困难以及大量数值计算等问题。

That trend has been profitable for travel websites like Expedia (Nasdaq: EXPE ) and Priceline (Nasdaq: PCLN ), and it has led many travel-related companies, like Southwest Airlines and hotel operator Marriott, to spare no expense in making information available to you directly.

这种流行给旅游网站像 expedia和Priceline带去了利润。它引领了很多旅游相关企业，像西南航空和酒店代理Marriott，免费直接为你有效地提供资讯。

The thermograph obtained by a thermal imaging system is only the distribution of radiant temperature of the surface of measured devices,not the true temperature.

用红外热成像系统直接获得的热像图，是被测器件表面辐射温度的分布，并不是真实温度的分布。

The curve obviously declined from the low frequency to the middle frequency section, and was reduced to zero in the high frequency section, which objectively showed the change in imaging characteristics of the eyes from the low to high frequency areas.

PSF分析系统可直接采用屈光系统MTF曲线表达人眼的成像特征，该曲线MTF值从低频至中频迅速下降，高频趋向缓和至零，定量并客观地表达了人眼成像质量从低频至高频的改变。

Results:(1) Spin-echo sequence included axial, coronal and sagittal images. In T1-weighted images,the medulla oblongata is isointense,the cistern is hypointense; in T2-weighted images,the medulla oblongata is isointense, CSF shows hyperintense, and the arteries of posterior fossa appear hypointense flow voids. The cisternal cranial nerves are not clearly demonstrated in the routine spin-echo images. In 3D-time of flight images, the brain tissue shows isointense, CSF is hypointense, the artery shows hyperintense,and the cranial nerves show linear isointense.

We also discussed the signal characteristics of each kind of tumors.MRI has ben showing great advantage in evaluating the tumors of the spinal canal:nonionizing radiation. noninvasive, no bony artifacts, multiple planes imaging, there is no need to inject agents to the canal, and one image can demonstrate multiple lesions.

MRI在评价椎管肿瘤方面显示出世大的优越性：无电离辐射、无创伤性、无骨伪影、多平面成像、不需椎管内注入造影剂、多发病变一次成像，直接显示肿瘤信号及其与周围结构的关系，定位及定性准确率高。

With the premise of assuring pixel immixing model, wether good or bad it is, the choice of endmembers directly influence accuracy of pixel unmixing.

在混合像元分解模型确定的前提下，端元组分选择的优劣直接影响混合像元分解的精度。

In this thesis, an all-digital phase-locked loop with large multiplication factor is presented. This circuit can be applied to the video system as a clock generator. It receives the horizontal synchronous signal from the graphics card and then generates a high frequency pixel clock according to the monitor resolution setting to acquire the video signal data. The stability of this sampling clock affects the display image quality directly. If the pixel clock is not stable, the display image will be glittering or jittering.

在本论文中，我们提出一个高频率倍数的全数位式锁相回路，此电路可应用於视讯系统中的时脉产生器，其主要功能是接收显示卡发出的水平同步讯号，并依据使用者设定的萤幕解析度，产生高频像素时脉来撷取视讯讯号资料，取样点的稳定度直接影响到显示画面的品质，若是像素时脉不稳定，则显示画面会闪烁或抖动。

With it, you can mirror the CD directly into a CD-ROM drive, that is to say you can not release the image to your hard disk or CD-ROM can be re-creates the same as with the drive.

有了它，您就可以把光盘镜像直接变成壹个光盘盘符，也就是说您可以不用把镜像释放到硬盘或者再刻出光盘就可以当做光驱壹样用了。

So the technique of uncooled microbolometer infrared imaging has become one of the main points from now on. In the paper uncooled microbolometer infrared imaging system is studied from focal plane character, image dealing and application. The details are in the following: On uncooled microbolometer infrared focal plane aspect: first, the work principle of microbolometer, manufacturing technology of microbolometer infrared focal plane, temperature balance equation of microbolometer detector are analyzed. The performance of microbolometer detector is predicted by model. Second, the infrared focal plane is the core of infrared system, whose quality can determine the performance of the system. It is the precondition that the high quality of every detective unit maintains the qualification of the focal plane. The even degree of detective units has great influence on imaging characters if the other characters of detective units are normal.

本文以非致冷微测辐射热计红外成像系统为对象，从焦平面特性、图像处理和红外系统应用方面展开分析、研究，具体内容如下；在微测辐射热计红外焦平面方面，首先分析了微测辐射热计的工作原理、微测辐射热计红外焦平面的工艺制作、微测辐射热计探测单元的温度平衡方程，根据有关参数对其特性进行建模预测；其次，红外焦平面是红外系统的核心，它的质量的好坏直接决定系统性能，因此保证其各探测单元的高性能是维护焦平面品质的前提，在探测单元其它特性正常的情况下，各探测单元之间特性的均匀程度对系统成像性能有极大影响，为此本文提出自适应滤波多项式焦平面非均匀性校正算法从软件角度解决焦平面的固有的噪声问题。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
