Also, the difference in pressure between any two points in a bed is roughly approximated by the static head of bed between these points . 還有,床層中任意兩點(diǎn)間的壓差大致等于這兩點(diǎn)間床層靜壓頭。
The difference in pressure between the and - medium chambers deflects the diaphragm 和-介質(zhì)室的壓力差使膜片發(fā)生偏轉(zhuǎn)。
This deflection measured travel is transmitted to the pointer via a push rod causing a pointer deflection in proportion to the difference in pressure 偏轉(zhuǎn)測(cè)量到的移動(dòng)通過推桿傳遞到指針,使指針根據(jù)壓差發(fā)生偏轉(zhuǎn)。
Goal function is to minimize the expense of trickle system ; the difference in pressure of drip line is thought as restriction condition ; we may obtain optimizing len gth of drip line by answering to the goal function 本文在灌水小區(qū)面積一定的情況下,以田間管網(wǎng)的造價(jià)與運(yùn)行費(fèi)用最小為目標(biāo)函數(shù),以毛管的壓力差為約束條件,求得田間灌水小區(qū)內(nèi)毛管的經(jīng)濟(jì)長(zhǎng)度。
During the passage of tornadoes or waterspouts , the direct impact of very strong winds and the difference in pressure between the interior and outside of a building can shatter weak structures , and even blow away trees and vehicles 渦旋中心附近的氣壓非常低,并且風(fēng)力強(qiáng)大。卷風(fēng)經(jīng)過時(shí),單薄的建筑物可能會(huì)抵受不住強(qiáng)大風(fēng)力及室內(nèi)室外的氣壓差而損毀,樹木及汽車等會(huì)被吹起。
Great difference in pressure for two flow made pressure wave system and it help to extend the delay time for gas in chamber , which increases combustion effusion . second , to increase combustion effusion , the inlet temperature of air and gas should be enhanced in the range of heat releasing in chemical reaction . third , the first work condition is unburned absolutely and the second work condition is burnt in shear layer of inlet and the end of down wall zone in straight segment 對(duì)于壓力差很大的兩股氣流,所形成的壓縮波系的結(jié)構(gòu)可以增加燃?xì)怦v留時(shí)間,提高燃燒穩(wěn)定性;為了提高擴(kuò)散燃燒的效率,在保證能放熱的化學(xué)反應(yīng)溫度范圍之內(nèi),應(yīng)適當(dāng)提高燃?xì)饧翱諝獾膩砹魅肟跍囟?燃?xì)鈬娮鞈?yīng)居于燃燒室軸線上,是改進(jìn)超音速燃燒室結(jié)構(gòu)的一種思路。
During the passage of tornadoes or waterspouts , the direct impact of very strong winds and the difference in pressure between the interior and outside of a building can shatter weak structures , and even blow away trees and vehicles . there have been reports of small boats capsizing in nearby waters on encountering waterspouts 渦旋中心附近的氣壓非常低,并且風(fēng)力強(qiáng)大。龍卷風(fēng)經(jīng)過時(shí),單薄的建筑物可能會(huì)抵受不住強(qiáng)大風(fēng)力及室內(nèi)室外的氣壓差而損毀,樹木及汽車等會(huì)被吹起。在海上曾經(jīng)有小型船只遇到水龍卷而沉沒。
