  2. The strong deviation theorems are new type theorems established by using the notion of the likelihood ratio. professor liu wen frist applied an analysis method in solving a class of strong deviation theorems for a sequense of random variables. later professor liu wen studied the shannon - mcmillan theorem in information theorems [ 2 ] - [ 8 ] and deviation theorems of non - negative continuous random variables [ 10 ] - [ 11 ] by using the analytic technique and obtained some strong deviation theorems. the chapter 2 of the paper studied a class of strong deviation theorems of function of two variables of information sources and obtained a further study of shannon - mcmillan theorem of markov information sourses by definning the using concept of entropy density divergence. the chapter 3 of the paper studied a class of strong deviation theorems of non - negative continuous random variables by using tool of transformation of laplace. information theory, as a branch of applied probability theory, becomes more and more important in appling

    劉文教授在解決大數定律中，用首創的分析方法得到一類隨機變量序列的強偏差定理。后來，劉文教授把分析方法用於信息論中shannon - mcmillan定理和連續型隨機變量的偏差定理的研究，得到了若干強偏差定理。本文的第二章是引進任意信源相對熵密度偏差的概念，並利用這個概念研究任意信源二元函數的一類強偏差定理，得到了馬氏信源shannon - mcmillan定理的一個推廣。

    但根據我國犯罪構成的四要件理論，認識的內容非常繁雜，理論上也有很大的分歧，但相比較而言，認識一要件說（僅僅包括犯罪客觀方面的事實）更具備可行性。
  6. Based on the rate - equation theory of four - level system, the expressions of threshold pump power, output power and slope efficiency are given. the influence of space distribution of pump light ( the position of focusing point, dimension of pumping light and divergence angle ) to the output characteristics are also discussed. then, by investigating the effects of thermal effect of laser crystal on the size of laser cavity mode, we obtain the mode - matching principle of high power laser diode end - pumped solid - state lasers

    其中，在泵浦光的空間分佈變量中我們分別考慮了泵浦光聚焦后的腰斑大小、聚焦腰斑在增益介質中的位置以及泵浦光在介質中發散角的影響；然後我們研究了在高泵浦功率下激光晶體因吸收泵浦光而產生的熱效應所導致的熱透鏡效應以及熱致衍射損耗，通過分析它們對振蕩激光腔模尺寸的影響，得到了高功率半導體激光二極體端面泵浦固體激光器模式匹配的要求，為高功率連續單頻nd ： yvo _ 4激光器的優化設計提供了理論依據。
  7. In chapter 3 we analyze a useful statistical method - projection pursuit ( pp ), including its basic theory and application. we put out definitions of projection index and projection pursuit, then prove that pca is a special case of pp with sample variance as projection index and list some indices often used. in section 3. 3 we apply pp with information divergence index to hyperspectral image, and demonstrate the advanced ability of it by the comparison between it and pca

    第三章圍繞一種新興的統計降維方法? ?投影尋蹤展開討論，概述投影尋蹤的一般理論，定義了投影指標和投影尋蹤的概念，證明了傳統的主成分分析方法是投影尋蹤的一個特例，證明了正態性與friedman指標為0的等價性；第三節針對高光譜圖像處理問題，從實例和理論兩個方面，論證了以信息散度為指標的投影尋蹤方法在提取信息的能力上優于以方差大小作為衡量信息量多少標準的主成分分析方法。
