查询词典 electron beam

Purpose: The aim of this study is to present a novel technique in which uniform dose to the whole body as well as the soles and vertex of scalp can be achieved in one electron beam treatment fraction. An experiment was undertaken with a home-made aswirl board that enables the patient to lie in supine or prone position for treatment.

目的：一般在病人做完全身电子射线治疗后，病人的头顶及脚底会有剂量不足的现象；此时能够做的就是采事后补足剂量的措施；如何在治疗过程中，同时让病人的头顶及脚底及全身都给到足够且相同的辐射剂量是此篇研究的主题。

The Au/AuGe(88/12)/Au back-contact metal structure was deposited on the GaAs substrate using an electron-beam evaporator. Various post thermal treatments were employed including conventional furnace and rapid thermal annealing. It was found that the outer Au layer thickness and furnace annealing temperature had large effects on the specific contact resistance.

在实验中我们在砷化镓基板背面进行蒸镀背金结构，而此背金结构是由三层金属所组成，分别为金/锗(12%)金(88%)/金，我们控制最外层金的厚度来量测与观察特徵接触电阻的大小，同时改变炉管加热的温度与快速热退火系统做比较，背金结构之元素分布比较可由欧杰电子分析得到，而扫描式电子显微镜可分析其两者之间的表面形貌差异。

这些器件不需要外加磁场聚焦电子束，波束相互作用区短，功率容量大，结构简单，输出信号稳定，可以实现器件的小型化；电子束调制和微波能量提取分开进行，可以提高器件的效率而且便于参数调节。

By using of the theory and simulation methods above, the inject cavity, buncher cavity and output cavity are analysed separably. With An annual electron beam of voltage 500kV, and current 3kA, average output microwave power 455MW and peak power 1.3GM is observed, bandwidth is 60MHz, the efficiency is 30.3%, the gain is about 36.8dB.and the frequency is 2.85GHz, The amplitude and phase of output microwave is stable.

最后运用上面所得出的一系列理论及模拟方法，分别对相对论速调管的注入腔、聚束腔和输出腔的工作特性进行了详细的分析和优化设计，我们采用3kA和500kV的环形强流相对论电子束，最后得到了工作频率为2.85GHz、饱和增益为36.8dB、效率为30.3％、带宽大约60MHz、平均功率为455MW，峰值功率可达1.3GW的微波输出的相对论速调管，输出微波的幅值平稳，相位稳定。

Methods 26 patients with intermediate or advanced pancreatic head carcinoma underwent cholecystojejunostomy combined with intraoperative radiotherapy with an electron beam on carcinoma from May 1996 to May 1998. The catheter of multifunctional implantable drug delivery system was inserted via gastroduodenal artery for postoperative perfusion chemotherapy.

对26例中晚期胰头癌患者施行了胆肠吻合术，手术中行直线加速器肿瘤区直接照射，同时手术中经胃十二指肠动脉置入埋入式化疗泵，手术后行肿瘤区灌注化疗。

The radiation plant that in recent years countrywide various places builds the foundation (cobaltic - 60 irradiation implement with electron beam accelerator) the amount rises a situation, and the radiation treatment application in main field, can say our country is preliminary already now formed a kind of brand-new radiate to machine an industry, aim to satisfy the demand that economic prosperity increases increasingly.

根据近年来全国各地区所建立的辐射装置(钴-60辐照器与电子束加速器)的数量增长情况，以及辐射加工在主要领域中的应用，现在可以说我国已初步形成了一种崭新的辐射加工产业，旨在满足经济繁荣日益增长的需求。

CFB (Circulaiing Flued-bed Boiler), which could desulphurize by adding the lime stone in boiler, was adopted in the project of petroleum coke taking the place of oil; IGCC was adopted in coal to gas project; PC+FGD, such as limestone/plaster wet type desulfurization, liquid spray flue gas desulfurization, electron beam flue gas desulfurization and sprayed dry type desulfurization etc., was adopted in the other projects of thermoelectricity. Desulfurization inside boiler needs less running expenses but high investment and lower desulfurization efficiency.

主要为：高硫焦代油项目燃用石油焦，采用循环流化床炉内加石灰石脱硫；煤造气采用整体煤气化联合循环工艺；其余热电项目则采用煤粉炉加炉外烟气脱硫，具体的脱硫工艺选择有石灰石／石膏湿法脱硫、液柱喷射烟气脱硫、电子束法烟气脱硫以及旋转喷雾干燥法脱硫。

An electron beam does not diffract at atomic scales, so it does not cause blurring of the edges of features.

由于电子束在原子尺度不会绕射，所以它不会使得图案细节的边缘模糊。

This paper studies several dosimetric characteristics of alanine/ESR dosimetry system on 60Co Y -ray and electron beam irradiation.

本文研究了丙氨酸/ESR剂量体系对于60Coγ射线和电子束辐照的剂量学响应性能，并通过实验确定了丙氨酸薄膜剂量计的最佳测量条件。
