In present dissertation, most stirpses are repartitioned and redefined, and the structure characteristic, course of formation, cause of formation, function and risk of stirpses are analyzed. the main conclusions are : [ 1 ] rapid development of corporations engenders urgent demand of financing, conflict between capital market imperfection and demand of financing leads corporations to control listed corporations by purchasing " shell " and enhance it ' s financing capability ; [ 2 ] two kinds of pricing institution of stock provides stirpses for controlling listed corporations by low cost, monitoring institution imperfections provides corporations for operating listed corporations. adjust of national assets provides more " shells " ; [ 3 ] more private corporations purchase listed corporations, some of them form stirpses ; [ 4 ] stirpses have positive influence about adjusting industry and enhancing capital market financing function ; [ 5 ] stirpses magnify financial risk by controlling listed corporations, and transform listed corporations from shareholders benefit to block shareholder benefit, having tendency of infracting shareholders benefit
本文主要的結論： [ 1 ]中國企業的迅速發展對融資有迫切的要求，中國國內資本市場發展不完善與這種強烈的融資需求的沖突導致了企業尋求通過買「殼」的方式控制上市公司，以此來提高自身的融資能力； [ 2 ]中國上市公司股票的兩種定價機制為「系」低成本控制上市公司提供了可能，監管機制的不完善為「系」提供了操縱上市公司的空間，國有資產在調整過程中從部分競爭行業退出，為資本市場提供了一定數量的「殼」資源； [ 3 ]民營企業紛紛買「殼」上市，在這個過程中，部分實力突出的企業形成了「系」 ； [ 4 ] 「系」現象對進行行業整合、提高資本市場融資能力等方面起到了積極的作用； [ 5 ] 「系」通過對上市公司進行的操縱放大了金融風險，將上市公司的股東利益最大化變為大股東利益最大化，存在著侵害小股東利益的潛在傾向。 -

Analysis shows that when summer precipitation in north china is richer ( less ), tropical east pacific ssta is colder ( warmer ) phase, and slp and 500hpa geo - potential height are negative ( positive ) anomaly over the asia, west pacific sub - high is northerner ( southerner ), and block high in mid - highs latitude happens less ( more ) than normal, east monsoon is stronger ( weaker )
分析表明華北夏季多（少）雨期，赤道中東太平洋ssta處于冷（暖）位相，在非洲大陸上slp利500hpa位勢高度均為負（正）異常，西北太平洋副高位置偏北（南） ，中緯度阻塞高壓發生頻率較低（高） ，東亞夏季風偏強（弱） 。 -
In this paper, based on the analysis of the rlem of theory foundation, computing method, preference, applicability, etc, we anatomized the rlem of three self - deficiencies and six scarcities. moreover, we adopted the parallel ways of contrasting the rlem with the fem and applied it to analyzing the impact of slide block of elasticity and plasticity, slip surface of coefficient and slip bed of elasticity, plasticity upon the stability of slope and in the plain linearity slope, the plain refracted line slope and the plain arc slope. in addition, we discussed the warp of between the lem of ( sarma, janbu, order, bishop, morgenstera - price, etc ) and the fem of result and the distributing of positive stress and shear stress on the slip surface
本文從剖析剛體極限平衡法的理論基礎、計算方法、參數選取、適用條件等方面入手，剖析了剛體極限平衡方法的3點自身缺陷和6點不足，並在此基礎上採用了剛體極限平衡法（平面滑動破壞法、 sarma法、傳遞系數法、普遍條分法、 janbu法、 bishop法、 morgenstern - price法）與大型有限元法對比研究的方法，分析研究了平面直線型滑坡、平面折線型滑坡、平面圓弧型滑坡在漸進破壞中邊坡的滑體彈塑性參數、滑麵塑性參數） 、滑床的彈塑性、以及極限平衡法無法考慮開挖應力釋放等因素對邊坡穩定性的影響與滑動面上的正應力、剪應力分佈規律、安全系數的解答的差異。 -
Finally, when the decomposition is proceeding to a symmetric positive definite matrix, the pivot may be very small or even negative. there provided several methods to overcome this shortcoming. ( 2 ) for the block strictly diagonally dominant matrices, there proved the existence and uniqueness of the block lu decomposition and the existence of the incomplete version
（ 2 ）證明了嚴格塊對角占優矩陣塊lu分解的存在唯一性與塊不完全lu分解的存在性，以及嚴格塊對角占優矩陣與不可約塊對角占優矩陣的塊jacobi 、塊gs ，塊sor 、塊ssor等基本迭代法的收斂性。 -
