step pressure change 中文意思是什麼
step pressure change
解釋
壓力躍變-
With the pressure in the simulated right ventricle ( srv ) and simulated left ventricle ( slv ) kept constant ( standard pressure condition for model iii ), each step of pressure decrease in the scc from 0 mmhg to - 5 mmhg, the sivs moved leftwards ( to the slv direction ) in a corresponding position and from 0 mmhg to + 5 mmhg, the sivs swung left - and rightwards at amplitude of 2. 2 mm. effects of intrathoracic pressure change on the motion of ivs under the same simulated respiratory
胸壓變化對室間隔運動的影響當模擬右心室和左心室壓力一定時，模擬胸腔內壓力每一次下降（從到一smmhg人模擬室間隔均向左側移位；當模擬胸腔內壓力相同，隨模擬右心室壓力的升高，模擬室間隔的運動幅度增大，當模擬右心室壓力升高到與模擬人心室相等時，模擬室間隔的運動幅度達最大。 -
Through experimental research, the calculation formula that the pressure highly - adjusted capacity of two cylinder chambers varied with the change of step load and the formula about hydraulic elements main parameter ( rated pressure ) were both made, which had important valuation in selecting the main parameter about this hydraulic system
通過試驗研究得出了出口節流調速系統中液壓缸兩腔壓力超調量隨負載變化的計算公式以及出口節流調速系統中液壓元件主參數（額定壓力）計算公式，有利於正確選擇系統的元件及主參數。 -
Accorded to the experimental research, under different flow area of flow valve and different adjusted pressure of relief valve, conclusion that the regulation of the pressure p1, p2 in the two cylinder chambers varied with the change of step load were as follows : when the throttle valve was series - connected on the return oil - line in the metering - out control system, under the same flow area and the same adjusted pressure of relief valve, with the incremental quantity of step load, the pressure highly - adjusted capacity of the hydraulic cylinder chamber with piston - rod decreased, meanwhile, it ' s time of rise, time to peak and the governing time all decreased. while the pressure highly - adjusted capacity of the hydraulic cylinder chamber without piston - rod increased
通過試驗研究得出系統在不同的流量閥開度、不同溢流閥調節壓力（進口壓力）下，液壓缸兩腔壓力p _ 1 、 p _ 2隨階躍負載變化的規律：當出口節流調速系統的回油路上串接節流閥時，隨階躍負載的增加，在相同流量閥開度、相同溢流閥調節壓力的情況下，液壓缸有桿腔壓力p _ 2 （ t ）的超調量是減小的，上升時間、峰值時間以及調整時間也是減小的；液壓缸無桿腔壓力p _ 1 （ t ）的超調量是增加的。 -
It was shown that when the soil pressure on the stepped rsrw was relatively small, its distribution form was zigzag, and would be affected evidently by unloading function of the step ; the potential fracture surface of the stepped rsrw was obviously different from the 0. 3h fracture surface proposed by the usual hypothesis, and would change with height - width ratio of the wall ; finally, its deformation characteristics were different from the vertical rsrw with single step
測試表明：臺階式加筋土擋墻的墻後土壓力較小，呈鋸齒形分佈，明顯受臺階卸載的影響；潛在破裂面與0 . 3h破裂面假定有較大差異，並隨擋墻的高寬比變化而變化；變形特徵不同於單級直立式擋墻。
