躍變壓力 的英文怎麼說
中文拼音 [yuèbiànyālì]
躍變壓力
英文
jumping pressure-
They varied both chamber pressure and mixture ratio, making use of a stepfunction change in the oxidizer injection rate.
他們通過用氧化劑噴射速率階躍函數變化的方法來改變氣室壓力和混合比。If grazing stress reached a threshold, genetic diversity of population emerged a transition point, with genetic diversity increased
當放牧壓力達到一個閾值時種群的遺傳多樣性有一個躍變點，遺傳多樣性又有增加的趨勢。As the most active and sensitive group in our modem society, university students are acutely aware of the impact of this variety. on one hand, they bravely face this variety, on the other hand, they urgently hope that they will receive the support and help from their family, society and friend, confronted with so many unavoided difficulties, nervousness and over - whelming press and thus feeling unpredentedly bafflement and agony
大學生，作為社會中最活躍、最敏感的群體，敏銳地感受到了這種變化的沖擊。他們一方面迎接著這種變化，另一方面，面對各種不可避免的困難、問題和壓力，心理和社會性的不成熟又使他們感到從未有過的迷茫和痛苦，迫切地希望能夠得到來自家庭、社會、朋友等方面的支持與幫助。In the summer stratified water column, the deeper the maximum depth of food distribution is, the stronger the dvm is performed ; the increase of the gradient of temperature in the thermocline layer can decrease the magnitude of the dvm and form the thermal barricade to the copepod ; the effects of the predation pressure on dvm is complex. on the one hand, the variations in the distribution depth of the predation pressure vs. the thermocline layer or the depth of the maximum food can modify the dvm patterns of the copepod. on the other hand, different predation pressure induces different dvm patterns
在夏季分層水體中，食物的最大分佈深度越大，動物向下遷移的幅度也越大；溫躍層的溫度梯度增大可以減小動物遷移的幅度，成為橈足類垂直遷移的溫度屏障；捕食壓力對垂直遷移的影響較復雜，一方面，捕食壓力的分佈深度與溫躍層或食物峰值的相對位置的變化能夠改變橈足類垂直遷移的模式，另一方面，捕食壓力強度不同，橈足類垂直遷移的幅度也不同，捕食壓力越大，遷移的幅度越大，當捕食壓力增加到一定程度，橈足類停止向上的遷移，大部分時間呆在水體深層，可能進入捕食壓力引起的「滯育」狀態。The temptation to use them is likely, sooner or later, to prove overwhelming.
遲早會使躍躍欲試的誘感變成壓倒一切的力量。Used the metering - out control system in which the hydraulic cylinder was the executive element as research object in this thesis, the experimental research about the effect on the pressure p1, p2 of the hydraulic cylinder chambers when series - connecting throttle valve or governor valve on the return oil - line under the step load changing have made
本文以單出桿液壓缸為執行元件的出口節流調速系統為研究對象，在其迴路上分別串接節流閥和調速閥，當負載發生階躍變化時，對液壓缸兩腔壓力p _ 1 、 p _ 2的影響進行了試驗研究。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。分享友人
