  1. First, in virtual of identification of flaws is a typical of in - verse problems, proceeding from time - harmonic electromagnetic maxwell ' s equa - tion and helmholtz equation, the uniqueness and existence of direct scattering problems including the numerical algorithms of diverse of boundary conditions is given. second, the uniqueness and existence of inverse scattering problems and the theory of ill - posed integral equation are briefly looked back upon. finally, indicator function method for boundary identification is set up under all kinds of boundary conditions for inverse scattering of homogenous and inhomogenous objects, meanwhile, the proof of possibility for near - field measurements and nu - merical simulation are given

    由於缺陷的識別是一類典型的反問題，因而首先從時諧電磁maxwell方程和helmholz方程出發，具體地闡述了求解正散射問題的有關方法，包括各種（夾雜）邊界條件下的數值解法，就解的存在性唯一性給予了肯定的回答；隨后對逆散射問題的理論作了簡短的回顧，包括解的唯一性以及非線性不適定積分方程的處理等；然後對均勻介質和非均勻介質的逆散射問題建立了在各種邊界條件下的邊界識別的指示函數方法，鑒于近場數據獲得的重要性，對近場測試時邊界識別的方法給予了相應的證明，並且實現了數值模擬。
  2. The questions the researcher concerned are which system will be chosen and how to obtain the good lithium ionic conductor materials, which is the basic departure of the paper. the addition of second phase in composite can change the interface structure and the conduction mechanism, improve the matrix conductivity and other function such as the sintering, crisping and so on, so the research of composites are an interesting field of the ionic conductors. the synthesis of lithium ionic conductor is often by solid state reaction, but this method needs high temperature and leads to the volatility of lithium which not only causes the drift of the compounds but gets the no well - distributed materials

    研究者所關注的問題是選擇新的體系進行研究，以期得到性能更好的鋰離子導體材料，這也正是本論文的基本出發點；復合離子導體中第二相的加入改善了基質的界面結構和導電機制，不僅可以提高基質材料的電導率，還可以在一定程度上改善材料的其它性能，如燒結性能、脆性和機械強度等。因此復合材料的研究是離子導體一個有廣闊前景的發展方向；合成鋰離子導體，特別是成分復雜的體系以傳統的固相合成法為主，但這種方法需要較高的溫度，容易引起鋰的揮發，從而造成產物組成的偏移，而且不易得到顯微結構均勻的材料。
  3. The present thesis is devoted to improving the excitation of the laser media ( gas mixture ) in the resonator of the high - average - power tea co2 laser by means of reinforcing the pre - ionization and eliminating the harmful impurity

    本文正是從提高預電離及清除混合氣中的雜質這兩個方面研究改善高平均功率teaco _ 2激光器腔內介質（混合氣體）的激發性能的。
  4. First, it is associated with the prepared conditions of spectral pure graphite electrode ; second, compared with the untreated graphite, the surface functional groups of ? oh and ? cooh on the treated one increased dramatically with hot concentrated h2so4 and the impurities on electrode surface decreased significantly with ultrasonic rinse. a sequence reaction mechanism was proposed for the eis of mn ( ) / mn ( ) on different graphite electrodes. the spectral graphite and the treated one can be suitable for the inert electrode of mn ( ) / mn ( ) cathode

    分析原因認為：一方面與光譜純石墨電極的制備條件有關；另一方面，與未處理石墨電極相比，處理石墨表面含氧官能團? oh 、 ? cooh明顯增多，而且超聲清洗又使其表面雜質含量減少，並提出了一個反應機理解釋mn （ iii ） / mn （ ii ）電對在三種石墨電極上阻抗譜的不同，說明光譜純石墨和處理石墨均可以作為mn （ iii ） / mn （ ii ）正極電對的惰性工作電極。
  5. It can remove water content, gas, impurity in oil as well as polar material in degraded oil, reduce acid number, medium loss number, remove free carbon and enhance withstand voltage and quality to guarantee operation of electric equipment
