  1. In the processing of single crystal materials, it was found that the sectorial distribution of light and shade appears on the surface, which is the main factor of affecting processing surface quality. therefore starting from the crystal structure, this paper first researched on kdp crystal mechanics characteristics in different crystal plane and orientation through theoretical analysis and nano - indentation experiment, separately calculated the young ’ s modules and shear modules of kdp in different crystal plane, and systematically analyzed the change rule of young ’ s modules and rigidity along with the crystal orientation

    在單晶脆性材料的加工中，人們發現加工表面產生明暗相間的扇形分佈，這種明暗相間扇形分佈是影響加工表面質量的主要因素，因此本文從晶體的結構出發，首先對kdp晶體不同晶面、不同晶向的力學性能進行了理論分析和納米壓痕實驗研究，分別計算了kdp晶體不同晶面上彈性模量和剪切模量，並系統地分析了彈性模量和硬度隨晶向的變化規律。
  2. The analysis result indicates that, kdp crystal mechanics characteristics, such as young ’ s modules, shear modules, rigidity and so on, have intense anisotropy, which is the reason of the scallop distribution of light and shade appearing on

    結果表明， kdp晶體材料的力學特性如彈性模量、剪切模量、硬度等具有強烈的各向異性特徵，這種各向異性特徵是單晶脆性材料超精密切削后產生明暗相間扇形分佈的根源，是影響加工表面質量的重要因素。
  3. The maximal power outputs of 37. 0 mw / cm2 and 30. 0 mw / cm2 for the p - and n - type laminated materials respectively at the temperature difference 490 have been experimentally obtained, which are about 2. 5 and 3. 0 times those of - fesi2. chemical analyses show that the interface failure between the bridge alloy and the semiconductor bi2te3 results mainly from the eutectic mixtures with low melting point and brittle compounds formed during welding and long time annealing at 190. it is found that the electrical properties of a laminated structure are mainly controlled by the wettability of the bridge alloy on the semiconductor surface

    發現： 1 ）疊層材料具有明顯優于均質材料的熱電性能，在490溫差下， p -型和n -型疊層材料的最大輸出功率分別達到37 . 0和30 . 0 （ mw / cm ~ 2 ） ，是同類型均質- fesi _ 2的2 . 5和3倍； 2 ）在焊接過程和190長時間退火處理過程中，焊接過渡層合金和基體半導體（特別是bi _ 2te _ 3 ）之間存在明顯的元素相互擴散，從而在過渡層中形成一些低熔點共晶體和脆性化合物，這是導致疊層材料破壞的主要原因； 3 ）焊接過渡層合金與半導體基體之間的潤濕性是影響界面層電性能的主要因素。
  4. However the study of metal - oxide hetero - interface is relatively less because the properties of metals and oxides usually differ extremely from each other. contrary to metals, the oxides are usually very brittle, elastically stiffer, insulating and exhibit less thermal expansion and their crystal lattice constants are different from metals. moreover, the preparation of specimen of metal - oxide interface is very difficult, the observation of searching a suitable interface under the electron microscope is also a tedious work

    然而，對金屬-氧化物界面結構的研究卻相對少一些，這主要是由於金屬與氧化物之間的性質相差非常大，與金屬相反，氧化物通常很脆、絕熱、熱膨脹系數小，晶格常數也不同於金屬，有的甚至相差很大，而且，制備金屬-氧化物界面比較困難，在電子顯微鏡下全面地觀察一個合適的界面也是一項令人乏味的工作。
