  1. A new type of thin film laps based on chalcogenide glass - sensitive materials was developed by means of silicon planar technology and thermal evaporation technique. the physical layer structure and the stoichiometric composition of the deposited glass materials have been investigated using transmission electron microscopy. depending on the conventional " two - electrodes " measuring set - up, these novel thin film sensors possess certain sensitivity towards heavy metals of seawater

    在laps的原理和應用基礎上,我們還進行了基於laps (光尋址電位傳感器)的微結構離子傳感器的研究:包括laps的結構優化設計、 laps器的微結構加工和工藝、針對被檢測的離子,採用硫玻璃等固態敏感材料,完成敏感薄膜分子合成的優化設計及與laps的界面結合的特性研究等,並將測結果和體傳感器進行較分析。
  2. However, the die attach layer delaminated after 500 cycles and pcb cracked in the underfilled samples after long time cycling. c - sam is employed to investigate the delamination in the underfilled samples. highly concentrated stress - strain induced by the cte mismatch between the bga component and the pcb board, coarsened grain and two kinds of intermetallic compounds ( nisn / nisns ) which formed during reflow and thermal cycle and their impact on the reliability of solder joints are discussed in this paper

    充膠樣品粗化尤為嚴; ? ni - sn間化合物包括兩層:其中,靠近ni焊盤的那層較平整,同時, eds結果分析表明其化學式近似為nisn ,而靠近焊料的那層呈板條狀,化學式近似為nisn _ 3 ,文獻表明其為亞穩相; ?充膠使得樣品最大應力范圍降了接近一個數級並降低了dnp的作用,同時,器失效模式變為晶元粘接層分層; ? c - sam結果表明本論文採用的充膠樣品,晶元粘接層分層起始於500周左右,而經過2700周循環的樣品,分層幾乎擴展到整個界面。
  3. Particulate reinforced metal matrix composites possess several additional advantages such as light weigh high specific strength and stiffness great shear strength. so they are widely used in many general applications in spaceflight car fittings sports goods areas. according to the difference of the wild phase ' s formation, the composite ' s manufacturing method can be divided into traditional way and in situ way

    顆粒增強基復合材料具有輕、強度與剛度高、剪切強度大等優點,因而被廣泛應用於航空航天領域和汽車配、體育用品等行業,其製造方法一般分為外加法與內生法。
