The feasibility of RDF as a dosimeter for measuring the electron beams of a medical accelerator was studied.

材料与方法：本研究所探讨RDF剂量计，为FWT-70系列的两种不同型号RDF剂量计；高能量电子射束为医用直线加速器所输出能量为6~20MeV的电子射束。

Objective: The sensitivity response of radiochromic dye film dosimeter with high energy electron beams was studied in this paper.

目的：本文系探讨辐射色染(radiochromic dye film； RDF)剂量计，对高能量电子射束的敏度反应，以作为度量放射治疗用电子射束剂量的可行性。

In chapter 3 of this work, we made some improvement on the base of original work and proposed a double exposure multi-beam interference method to fabricate a hexagonal lattice with irregular columns.

在以前的工作中，我们曾使用衍射分束器件得到三束呈伞状对称的光束相互干涉，制备出了对TE和TM两种模式同时具有较大带隙的二维三角结构光子晶体。

An important character of the program is its versatile for different data format, where such as it can be used for multi-beam or single-beam data set. This makes it quit useful to any speculated institute or echo-sounding group. Furthermore

此软体的另一重要特性是对於资料格式的接纳性，可同时适用於多音束或单音束等，不同来源的资料，可以直接运用於各种不同的微软视窗作业平台，具有推广之潜力。

A lifelong effulgence you are by my side

Thus, two kinds of intensity oscillations with phase difference of 180°can take place corresponding to the specular elastic diffraction and diffuse scattering.

因此在不同的观测条件下可出现二种相位差180°的强度振荡情形：镜向弹性衍射束强度振荡和漫散射束强度振荡。

At four,eight or sixteen week after operation,the angiogenesis of NGF was evaluated with Hematoxylin and Eosin staining and electron microscope.

术后4、8、16周观察再生神经的大体形态，并用HE染色和透射电镜观察再生神经的束间及束内血管分布。

Therefore this imaging system can realize two kinds of X-ray radiology: reverse geometry X-ray and X-Scan imaging, and several CT scanning methods, such as equiangular fan-beam CT, equispatial fan-beam CT, helical/spiral CT, cone-beam CT with circle orbit, cone-beam CT with circle-plus-line orbit.

这样就可以实现倒置结构的X射线成像方法、等角扇束的扫描方法，以及本文所提出的凹面源加点探测器的锥形束扫描方法，而且还避免了使用成组点探测器带来的性能不一致性。

When I do count the clock that tells the time, And see the brave day sunk in hideous night, When I behold the violet past prime, And sable curls all silvered o'er with white: When lofty trees I see barren of leaves, Which erst from heat did canopy the herd And summer's green all girded up in sheaves Borne on the bier with white and bristly beard: Then of thy beauty do I question make That thou among the wastes of time must go, Since sweets and beauties do themselves forsake, And die as fast as they see others grow, And nothing 'gainst Time's scythe can make defence Save breed to brave him, when he takes thee hence.

当我数着壁上报时的自鸣钟，见明媚的白昼坠入狰狞的夜，当我凝望着紫罗兰老了春容，青丝的卷发遍洒着皑皑白雪；当我看见参天的树枝叶尽脱，它不久前曾荫蔽喘息的牛羊；夏天的青翠一束一束地就缚，带着坚挺的白须被升上殓床；于是我不禁为你的朱颜焦虑：终有天你要加入时光的废堆，既然美和芳菲都把自己抛弃，眼看着别人生长自己却枯萎；没什么抵挡得住时光的毒手，除了生育，当他来要把你拘走。

Based on the previous literatures, the following major innovation works were carried out in this dissertation:(1) The derivatization reaction conditions of ephedrine and pseudoephedrine with sensitive derivation reagent in aqueous system were studied and two new methods were developed for the assay of them by microemulsion electrokinetic chromatography and micellar electrokinetic chromatography with LIF detection. The sensitivity and analysis times were greatly improved compared with the previous reports;(2) A new method of CZE with indirect LIF detection was developed for the simultaneous determination of six coumarin compounds (esculin, esculetin, isofraxidin, genistein, naringin and sophoricoside) with fluorescein as the probe. The proposed method enlarges the application range of LIF detector, and provides new approach for the analysis of certain compounds difficult to derivatize;(3) Based on the above research, an MEKC with indirect LIF detection method for the simultaneous determination of adenine and guanine in DNA extracts from fungus, maize and soybean was established;(4) A new method for the investigation of the complexes formed between human serum albumin and ampicillin sodium under the simulated physiology conditions using laser light scattering technique was developed.

该论文在综述前人工作的基础上，开展了如下未见文献报道的创新性的研究工作：(1)使用灵敏的衍生试剂对麻黄碱和伪麻黄碱在水体系中的衍生反应条件进行了系统研究，建立了微乳电动色谱-激光诱导荧光检测法和胶束电动色谱—激光诱导荧光检测法测定麻黄碱和伪麻黄碱的灵敏分析新方法，与以前的报道相比，灵敏度和分析时间均有很大改善；(2)使用荧光素钠作为背景荧光试剂，建立了同时分析测定六种黄酮类化合物(秦皮甲素、秦皮乙素、异秦皮定、染料木素、柚皮苷和槐角苷)的毛细管区带电泳—间接激光诱导荧光检测新方法，扩大了激光诱导荧光检测的应用范围，对难衍生化合物的分离分析提供了一种新思路和新途径；(3)以荧光素钠作为背景荧光试剂，建立了一种用于同时测定食品提取DNA中的腺嘌呤和鸟嘌呤含量的胶束电动色谱—间接激光诱导荧光检测新方法；(4)用动态和静态激光散射法研究了模拟生理条件下人血清白蛋白与氨比西林钠盐相互作用所形成的复合物，为药物分子与蛋白质的相互作用、药代动力学等的研究提供了一种新思路。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
