The relationships between the accumulation of gas hydrates and the typical diapirs in passive continental margin are summarized in primary in this paper which suggest that the factors in passive continental margin including the thick sediment layers, plastic substance, high pressure fluid, outboard volcanic activities and the process of stretch - rupture provide favorable conditions for the formation of the diapirs which can form advantageous environment for gas hydrates coming into being
初步總結了被動大陸邊緣中典型底辟構造與天然氣水合物的成礦關系，認為被動陸緣內巨厚沉積層、塑性物質與高壓流體、陸緣外側的火山活動及張裂作用，為底辟構造發育提供了條件，形成了水合物成礦的有利空間。 -
Based on the hypothesis that the rear side of retaining wall is pitching and coarse, and the filling surface is gradient, taking viscous filling as the object of study and using the static balance method, a study has been conducted on the earth pressure on the rear side of retaining wall under the sliding wedge ' s limiting equilibrium condition, and generated a general form for active earth pressure and passive earth pressure
摘要基於擋土墻墻背俯斜、粗糙且填土表面傾斜的情況，以粘性填土為研究對象，用靜力平衡方法研究了擋土墻后滑動土楔體達到極限平衡狀態時作用於墻背的土壓力，提出了主動土壓力和被動土壓力的一般形式。 -
The rankine soil pressure theory is always accepted as the foundation of calculations of the soil pressure in practice. but as we know, the ignorance of the middle principal stress and the utility of mohr - coulomb strength criterion in the two - dimensional stress state make a blemish that the active soil pressure is bigger and the passive soil pressure is litter than the real
朗肯土壓力計算公式一直是工程實際土壓力計算的理論基礎，但是朗肯土壓力計算公式在推導過程中忽略了中主應力的影響，仍然應用二維應力狀態下的莫爾?庫侖強度準則，致使計算出的主動土壓力偏大而被動土壓力偏小。 -
The condition of water pressure acting on the both sides of cement - soil retaining wall is researched by computing the seepage field around the wall. it is illustrated that the coefficient of water pressure, which isn ' t constant along the height, is affected seriously by some factors, e. g., the distribution and relative hydraulic permeability of the soil beside the wall, the hydraulic permeability of its foundation, and the buried depth of the impervious layer. as a whole, the lateral pressure acting on the wall based on seepage is always smaller than that without regard to seepage in the non - excavated zone. moreover, the pressure based on seepage is greater than that without regard to seepage in the excavated zone if the coefficient of passive pressure is smaller than 1. 176. this case is of great advantage to the stability of the wall
通過計算水泥土擋土墻周圍的滲流場，研究了墻側水壓力的變化規律.結果表明：水壓力系數沿高程並非常數，且受到墻側土層分佈及其相對透水性、墻基土的透水性和下臥不透水層埋深等因素的嚴重影響.總體來說，考慮滲流時墻后的側壓力總小於不考慮滲流時的相應值，且當墻前的被動土壓力系數較小時，考慮滲流時該側的側壓力則大於不考慮滲流時的相應值，因此，這種情況有利於擋土墻的穩定 -

尾盤形態如當日盤口強勁，會在尾市半小時左右引發跟風盤的湧入，使股價脫離當日走勢傾斜率單邊上行，此時莊家會借機大筆提拉，以封死下一交易日的下跌空間，由於此時跟進的買盤都有強烈的短線斬獲利潤的兌現心理，所以尾盤若在搶盤時出現5以上的升幅，要小心次日獲利盤兌現對股價造成的拋壓以及莊家次日開盤借勢作打壓震蕩所帶來的被動，建議操作者不要在尾市過分追高搶貨，以免陷入莊家次日短期震蕩給倉位帶來的被動局面。
