赵小慢: 金币+10, 翻译EPI+1, ★有帮助, 这位大侠，我需要的是逐字的英文内容，不需要翻译出来的中文，不过还是谢谢你啊 呵呵 2013-09-08 13:30:22
phu_grassman: 金币+5, 翻译EPI-1, Thanks for your help. But the EPI should be given to the one who gives the best answer. 2013-09-11 06:42:34

(感谢奖赏) 前5分钟 = XRF (优点)简介 后1分钟 - ESRF 公司的独特 GaAs IC 成分分析 没说,但值得关注: XRF 应用范围窄,就业前景有限 数据进流量高,很难分辨噪音和有用数据 分析时间太短,不足以及时提供满意结果 LZ 如有兴趣投效ESRF,可先研究 -0- 刻度标准 (Calibration Standard) -1- 最后比较用的标准 -2- 含探测晶体的弹头(Head)设计 -3- 前置放大器(PreAmplifier) 设计 -4- 前置放大器与仪器其它部件的整合 -5- 如何应对"Compton Effect" -0-和-1- 好问不好找,学通了一辈子有用 -2-到-5- 是所有XRF公司请人的原因  |

what do you know about X-rays,we all know that they are used to take pictures of your bones, or see the contents of ??? but have you ever imagined the very powerful source of X-ray could also help solve industrial problems and perhaps speed up your innovation process.but yesthey can and……，a wide range of techniques is open to industry with the ERSF, DoctorGema Martinez-Criado, beamline responsible, will give us insights into X-ray Fluorescence Spectroscopy. X-ray Fluorescence analysis is a technique commonly used in ERSF for chemical compositions analysis,…… So most of the cases, we are applied the technique to mummies, to flyethches, to anything your tiny sample. like, some particles in , for microelectronics or , for elements that they are very low quantity. X-ray Fluorescence applications can be divided in five groups. Art&archeology like mummies,earth & environmental science for …… and the contaminations, materials science like micro, biomedical applicaitons,analyse cells and neurons, and finally geology in ocean science, the principle behind the technique is basicall the X-ray absortions, so we collect the light ,and we analyse by energy. Like this,we are able to determine how elements, which element are in the sample. The micro X-ray Fluorescence is basically consisted of three elements, the source, the ……, and the sample.Basically,we scan the sample in the bin, and we collect …… .From that spectrum,we are able to .like this, you are able to in 2D,If necessary we can collect X-ray difraction data.Like that we have not only the compositions, but to allow us to analyse at the same time.So in the end what we get is both the compositions and X-ray Fluorescen analysis compared to electronic In general, we have a large dynamic , we go from bbv to 100%, Sample size can be sorted according to the users' need, from cm, to mm to nanometer scope. We have two sations, one with micrometer beamsize and second with nanometer beamsize. so in principle,up to facing nanometers,samples can be accomodated and with the X-ray beam. In general, we can analyse samples in different environment, different temperture and pressure. semiconductor industry needs to incorporate devices into a single chip. That is why they need something useful applications, with higher speeda and lower price to crporate modulator onto a very single chip. To check whether this formation of chip is OK or NOT, we have been working on X-ray Fluorescencea analysis of the……, elements allover the waves. while X-ray Fluorescence maps allow us to …… while X-ray diffractions And the formation of both modu X-ray Fluorescencea can help us analyse chemical composition of a few sample with high solution to nanometer scales ……………………………… |
