To solve the exsisting problems in the realization of the LFM/CW radar, the thesis presents a technique for dynamically measuring the LFM/CW signals, which can accomplish the dynamic measurements of FM linearity, FM bandwidth and FM slop of the transmitted signals of LFM/CW radars. This technique creates an effective and accurate means of judging the performance of LFMCW radars. The linearity-correction techniques presented in the thesis successfully make the linearity of the transmitted signals of an actual LFM/CW radar reduce from approximately 25% to 0. 1%(or r. m. s linearity of 0.04%), better than the best results (0.22%) obtained by foreign researchers with complex linearization closed-loop in the same kind of LFM/CW radars, according to the published literatures during the last decade. In order to improve the capability of the real-time processing and range-cells management of LFM/CW radars, the principle of equivalent mixing by lacking-sampling process of band-pass real signals is proposed based on the well-proved improvedversion of sampling theorem of band-pass real signals. This principle is used to configure the range-segments processing of the beat signals of an actual LFM/CW radar. The techniques of system-background interference suppression and the beat signal's dynamic range suppression are proposed, and are realized in an actual LFM/CW radar to demonstrate their effectiveness.

XRD and EDS analysis indicate that at static condition, the composition of the scale is CO3, while the scale changes to CO3 at dynamic conditions. The increment in flow rate increased the thickness of the scale remarkably, but had little influence on the hardness and Young's modulus of the scale. The fracture toughness of the scale exhibited the lowest value at the flow rate of 0.5 m/s whereas the adhesion strength increased with increasing the flow rate.

结果表明，静态条件下形成的腐蚀产物膜的主要成分为CO3，动态条件下的主要成分为CO3；介质的流动能够促进腐蚀产物膜的形成，但对膜的硬度以及杨氏模量影响不大；腐蚀产物膜的断裂韧性随着流速的增大先下降后上升，流动状态下内层腐蚀产物膜的致密性较好，膜与基体的结合强度较高。

Carver, who draws on the research of Walter S. Avis," Crocus is a coarse, loosely woven material once worn by slaves and laborers and common in colonial New England. It probably took its name from the sacks in which crocus or saffron was shipped."

克雷格·M·卡弗尔在参考了沃尔特·S·阿维斯的研究资料后得出结论：& Crocus 原是新英格兰殖民区中奴隶和苦力穿的一种编织疏松，粗糙的布料，它很可能是由装载番红花和藏红花的布袋而得名&。

However, no additive effect could be found when caffeine and ETX were concomitantly incubated. Ruthenium red, which is a blocker of cation channels and perhaps a blocker of CICR, could inhibit the effects of caffeine and ETX by 94% and 80%, respectively.〓, replacing 〓 in Kreb's solution, inhibited ETX-evoked CGRP release by 82%. Ryanodine (1-100μM) or Tris-ATP had no effect on both basal and ETX-induced CGRP release.

钌红能分别抑制咖啡因或内毒素引起的CGRP释放，如以氯化镁代替Kreb's液中的氯化钙时，内毒素引起的CGRP释放可降低82%，Ryanodine 1-100μmol/L或Tris-ATP对CGRP基础释放和内毒素引起的CGRP释放均未见明显影响。

M \$ s If we only had some God in the country's laws, instead of beng in such a sweat to get him into the Constitution, it would be better all around.

如果我们国家的法律中只有某种神灵，而不是殚精竭虑将神灵揉进宪法，总体上来说，法律就会更好。

Long time hasn't written, sorry about that I was in Singapore for the past week. I was a jury for Asia 's First Film Festival. Watched lots of good film, got really inspired, there are so many good film makers I'm so happy I got to see them first. Just one very unfortunate issue popped up while I was gone. My eldest boy, Uni. Beautiful brown Shizu was seriously ill, he had acute kidney failure. He is better and out of the hospital now, we are trying our best to give him the quality of life right now. I just don't want to go out, wanna stay home with him all the time. But we have to finish the rest of the album and hand everything in before Christmas. Sorry about no writing again.

很久没有写博客了，对不起，我上星期於星加坡为 Asia's First Film Festival 当评审，看了很多好电影，很有启发性，还有很多电影制作人，很高兴能跟他们见面，当我不在港时，有一件很不幸的发生，我最大年纪的孩子– Uni 美丽的棕色西施得了重病，他患了急性肾衰竭，他现在已好多了，亦已经出院，我们现在尽我们所能去给他优质的生活，我不想外出，只想留在家中跟他在一起，但我必须要完成国语专辑的余下工作及於圣诞前交出所有东西，对不起啊，很久没有写博客。
