  1. 4. as for the three kinds of waterproof underlying surface, when rainfall intensity is strong, the rise process curve will steep in the process of discharge, and also speed of discharge to reach steady will quicker. but it produces little effects on duration of fall

    4 .對于透水性差的下墊面，雨強越大，流量過程的漲水曲線越陡，且達到穩定流量的速度也更快，但對流量過程的退水歷時影響不大。
  2. The cleavage rate of oocytes at 18 - 19h after hcg injection was clearly higher than those at 12 - 13h and 15 - 16h after activation ( 71. 67 % vs 7. 50 % and 55. 83 %, p < 0. 01 ). the rates of avtivation, cleavage and development of blastocysts after 22h started to fall, but with no difference with those of 18 - 19h ( p > 0. 05 ). to sum up, the optimal electric stimulation conditions of mouse oocytes at 18 - 19h after hcg injection is 2. 0kv / cm direct current field strength, 80us pulse duration, 3 times pulse and 0. 3mol / l mannitol medium with 0. 1 mmol / l cacl2 and 0. 1 mmol / l mgso4

    880和12 50o ） ，但與18l的卵母細胞組無明顯差異o 0刀5 ） 。綜上所述，在本實驗室條件下，以含ca刀、 mgh的甘露醇溶液為激活液，採用2刀by cm強度、 80呷脈寬、連續3次脈沖（每次間隔10min ）刺激注射hcg后18二9h的小鼠卵母細胞，可獲得較為理想的激活效果。
  3. The disease in jaw surface will be drop the bite force ; the bite force in the patient who disease in temporal jaw joint descent obviously than normal person ; serious mistake in join deformity, the acute damage in the area arthritis can also drop the bite force evidently ; compare to normal children, wenneberg fund that the bite force lower and the duration of the biggest bite force shorter in the children who fall ill of the chronic arthritis ; the bite force also be used in appraise of the recovery condition in surgical operation 、 disorder in jaw arthritis and the serious bone offset in bite lopsided etc. some materials, it will be produce polarization phenomenon inside when suffered some force in certain direction, at the same time, it produce opposite electric charge in two of the surface ; and resume to the station of on - electrification when removed the outside force ; change the direction of the outside force, the polarity of the electric charge also be changed, this kind of phenomenon is called as “ piezoelectric effect ”

    本文設計了石英晶體壓電傳感器，以它作為傳感元件把咬合力信號轉變成電信號;利用ts5860型準靜態電荷放大器把傳感器的電荷信號轉變成電壓信號;選用usb7822數據採集卡，編寫該數據採集卡的驅動程序，採集該電壓信號並送到計算機里;編寫labview程序對該信號進行處理，得出咬合力值和咬合力曲線，並把測量結果以電子表格的形式保存，以便做進一步的分析和研究。通過對該測量儀的靜態標定、動態標定、溫度漂移標定以及實際測量試驗，證實了本測量儀具有較高的靈敏度、受動態力和溫度變化的影響比較小、能實時地顯示咬合力曲線和較準確地顯示咬合力值，滿足了咬合力測量的要求。
  4. Simply stated, pmp is the greatest amount of rain that can possibly fall in a given duration over an area of given size according to hydrometeorological principles

    簡單來說，可能最大降水，就是在指定的時間內和地理面積上，根據水文氣象原理所能得到的最大降雨量。
  5. Numerical models were used to study how the infiltration into a slope varies with the rainfall intensity, rain fall duration, soil properties and how the infiltration influences the stability of a slope. a numerical program is coded to solve the transient seepage field by using the finite element and finite difference methods based on the saturated - unsatured soil seepage theory. a model for considering the variations of soil weight and shear strength is created / constructed and the corresponding program is coded

    本文針對受降雨影響顯著的非飽和殘積土土坡，運用飽和?非飽和土壤水分運動的理論和二維非穩態滲流有限元模型，模擬雨水入滲引起的暫態滲流場，將計算所得到的暫態孔隙水壓力分佈用於考慮了基質吸力影響的土坡穩定安全系數的計算當中，建立了考慮非飽和土土坡從雨水入滲到出現滑坡危險全過程的計算模型。
