According to the basic principle of microwave transmission line, a multilayer type absorbing material XFT which has a particular structure and good absorbing properties has been developed.

Study on Multilayer Type Antiradar Coating XFT

XFT多层型吸波涂层研究

Methods: Anoxia animal models were used to research the anti-anoxia effect of XFT and its ingredients.

方法：用物理、化学、药物等方法制备急性缺氧动物模型，对血府逐瘀汤的抗缺氧作用进行研究。

Renal arteriography revealed more characteristic changes, and the diagnosis of XGP relied on the clinical presentations and multiple imaging examinations.

肾动脉造影具有相对特征性，临床资料及综合影像分析有助于诊断。

Methods Eight cases of XGP were retrospectively reviewed from 1995~ 2002 for clinical situation, laboratory examination and management.

方法总结1995年至2002年收治的8例XGP的临床表现、实验室检查结果、影像学特点及治疗方法。

13 patients with XGP were diagnosed before operation.

13例术前诊断。

Methods 30 cases of XGP were retrospectively reviewed. The clinical management and follow up results were evaluated.

方法回顾性总结30例XGP临床表现、实验室检查结果、影像学特点及不同治疗方法的疗效。

Core contains a wide variety of GUI widgets and the IO transport for XHR requests to the server.

核心部分包含了各种各样的GUI组件和IO传输，后者用于将XHR请求发送给服务器。

Again, these options are the same across all of the XHR functions.

再一次说明，这些选项在所有XHR函数中都是一样的。

Now, each time you click Submit an XHR request is sent to WebSphere Process Server.

现在，每次单击Submit都会向WebSphere Process Server发送一个XHR请求。

The XHR objects are kept in an array that allocates one element for each form.

这些XHR对象保存在一个数组内，数组为每个表单分配一个数组元素。

An example of an XHR function is shown in Listing 22.

XHR函数的一个示例如清单22所示。

Then, the parameters are added to the XHR object.

然后，将参数添加到XHR对象。

This section presents the methods of the XHR object.

本节展示XHR对象的方法。

A novel technique has been successfully developed to calibrate the ultra high vacuum ( UHV) and extra high vacuum ( XHV), which consists of XHV/ UHV chambers, a flow separation and a gas supply.

超高/极高真空校准装置由极高真空（XHV）系统、超高真空（UHV）系统、流量分流系统和供气系统四部分组成。

Finally, we present a new type of XHV electrostatic saddle field ionization gauge which features very small electrode sizes and low outgassing/ sorption rates and high sensitivity.

最后提出一种极高真空鞍场规，与上述几种电离规相比，具有电极尺寸小、灵敏度高、吸放气率低等优点。

But in the next few years, things are sure to change, and you'll change too.

再过几年, 境遇一定会变更, 你就不会 像 现在这样了.

Will the changes in taxation affect you personally?

征税的变更将会影响到你个人 吗 ?

The changes will be introduced in April.

这些变更将于4月开始实行。

They have never altered their programmes by a single day.

他们一天也未变更过他们的节目。
