實驗室傢具承包商將負責抽風櫃，排風罩和酸堿櫃等排風點的最後連接，並負責和空調及排風系統的承包商確定實驗室區域的排風量，換氣頻率等具體技術要求，確保實驗室的安全。The fa cup draw has been relatively kind again with a home tie against either norwich city or blackpool to look forward to, along with the first - and hopefully not the last - final of the season in the carling cup, time to get the red carpet prepared once more
足總杯的抽簽是主場對陣布萊克普爾或者諾維奇城，又是一次不錯的運氣；還有本賽季第一次? ?肯定不是最後一次啦? ?決賽拉開帷幕，就是聯賽杯，又要到了準備紅毯慶祝的時候了。The theoretical analysis of large cryocondensation pump for nbi was mainly concerned. this paper emphasized on analyzing and calculating the heat load of cryocondensation pump, simulating thermal transmission coefficient and molecule transmission coefficient of radiation baffle according to monte carlo method, analyzing the process on cryo - surface and the factor of affecting pumping speed and hydrogen layer thickness of influencing cryo - parameter, etc. finally by verifying the pumping speed on large cryocondensation pump for neutral beam injection system, the pumping speed of 4. 0x105l / s ( for h2 ) was proven to be reasonable
本文首先介紹了中性束注入系統的國內外發展狀況，闡述了中科院等離子體所ht - 7中性束注入系統的構成，主要對用於中性束注入系統的大型低溫冷凝泵的特性進行了理論分析；對冷凝抽氣面的熱負載進行了分析計算；用蒙特卡羅法對輻射擋板的分子傳輸幾率與熱傳輸幾率進行了模擬計算；研究了低溫表面的處理方法對抽速的影響以及氫層厚度對各低溫參數的影響；最後對用於中性束注入系統的大型低溫冷凝泵的抽速進行了驗證，得出的結論是：選取40萬升秒的抽速是合理的。On the base of the soft about the deformation of aerodynamic configuration of mav, the advanced controlling technique of the deformation o f aerodynamic configuration about the prototype mav will be explored. based on the characteristic of micro air vehicle, this paper abstracted the aerodynamic evaluation mathematics models, developed a aerodynamic engineering estimation program, all kinds of aerodynamic configuration was compared and analyzed, found the perfect configuration and got the prototype of mav. abstracted the model about the deformation of aerodynamic configuration on base of the method of vortex lattice, developed the program for researching the performance of the deformation of aerodynamic configuration
本文針對mav的具體特點，抽象出mav的氣動工程計算數學模型，建立起氣動工程估算環境，對各種氣動布局進行了氣動特性比較分析與綜合，尋求出理想的mav氣動布局方案並提出mav原型機，抽象出基於渦格法的氣動外形形變的數學模型，建立起氣動外形形變性能研究環境，探討新型的飛行控制方法和氣動力控制策略，在得出氣動外形形變模型的初始方案后，對其進行進一步的優化，最後得出理想的氣動外形形變執行機構組合陣列。It is postulated that the reflux could have contained droplets of contaminated sewage present in the soil stack, be dispersed into the bathroom, and be extracted by the bathroom exhaust fan into the light well between adjacent units. the contaminated droplets could then enter other units through open windows
我們推測這氣流可能把存於污水管內帶病毒的水滴散發至浴室內，而浴室的抽氣扇亦可能把這些水滴排放在分隔相鄰單位的天井，最後帶病毒的水滴通過窗戶進入其他單位。分享友人
