2. In accordance with coal sample observation by scanning electron microscope ( sem ) and researches based on such subjects as anthracology , tectonic geology and material mechanics , the endokinetic fractures in coal are further classified into dewatering fractures , condense fractures and static pressure fractures , while the exogenetic fractures are further divided into tensile fractures , pressure fractures , shrink fractures and slack fractures , consistent with the development regularity of the geometric shapes , sizes and arrangement of fractures
   摘要分析、歸納了大量的掃描電子顯微鏡觀測結(jié)果，以煤巖學(xué)、構(gòu)造地質(zhì)學(xué)研究?基拙，依鋸煤中顯微裂隙的形態(tài)、大小、排列組合等發(fā)育特征，將內(nèi)生裂隙進(jìn)一步劃分?失水裂隙、縮聚裂隙、靜壓裂隙，將外生裂隙進(jìn)一步劃分?張性裂隙、壓性裂隙、剪性裂隙、松弛裂隙。
3. We present two different frameworks to analyzing the high frequency time series : first , regularly spaced sampled observations , which is sampled with interval of one hour , one minute even one second ; secondly , the irregularly spaced data , such as transaction by transaction data 。 the main work and innovations of the dissertation include : 1 . through empirical research of high - frequency time series of shanghai composite index , the paper researches the different statistical properties on different frequency
   高頻時間序列的分析與建模是金融計量學(xué)的一個全新研究領(lǐng)域。金融市場中高頻時間序列分為兩類:一類是采樣間隔相等的數(shù)據(jù),比如一小時、十分鐘、五分鐘、甚至是以秒為單位采集的按時間先后排列的等時間間隔的數(shù)據(jù);另一類是指對交易過程實時采集的數(shù)據(jù),也就是每筆交易的數(shù)據(jù)(顯然是不等間隔的數(shù)據(jù)) 。
4. Contrasting this , in feedback control the most majority of complex systems are controlled using sampled observations of system behavior taken at discrete time instants . thus the resulting controlled systems are hybrid systems , which are called sampled - data systems , involving both continuous - time and discrete - time signals . the investigation of sampled - data systems is motivated primarily due to the widespread use of digitally implemented controller in present - day feedback control of continuous - time systems
   工程實踐中遇到的動態(tài)系統(tǒng)通常是連續(xù)時間系統(tǒng)，與此相反，大多數(shù)復(fù)雜系統(tǒng)的反饋控制卻是通過觀察采樣點上的系統(tǒng)行為來進(jìn)行控制的，結(jié)果所得到的反饋控制系統(tǒng)是個混合系統(tǒng)，它含有連續(xù)信號和離散信號，這樣的系統(tǒng)稱之為采樣系統(tǒng)，當(dāng)今連續(xù)受控系統(tǒng)中數(shù)字控制器的廣泛運用促進(jìn)了對采樣系統(tǒng)的研究，已有的線性采樣系統(tǒng)理論顯然不能滿足處理非線性采樣系統(tǒng)的需要，因此近年來非線性采樣系統(tǒng)的分析與設(shè)計已經(jīng)成為國際控制論界的持續(xù)的研究熱點之一。
