jet exhaust 中文意思是什麼
jet exhaust
解釋
排氣噴口-
By linear regression analyzing of the concentration of plankton microbe and settling microbe, we get the relationship between plankton microbe, settling microbe and air exchange rate, which reflect the randomness of bacterium in dynamic state. controlling the pressure difference effectively by adjusting forced draught blower and exhaust blower. comparing the jet fluid of different supply - air outlet, the diffuse pore plate is suit to assembling cleanroom
通過對測得不同換氣次數下裝配式潔凈室室內的浮遊菌濃度和沉降菌濃度的一元線性回歸分析得出浮遊菌濃度和換氣次數的關系、沉降菌濃度和換氣次數的關系以及浮遊菌和沉降菌之間的關系，反映了動態情況下，細菌運動的隨機性。 -
New rcps, which are designed to be visually attractive as well as odourless, are equipped with water scrubber systems, vehicle exhaust extraction systems and high pressure water jet cleaners

And then, some improvements have been made on the old single tube pressure wave refrigerator experimental system. the experimental research, such as the ratio of gas charge time to gas exhaust time ( ), the frequency of the jet flow ( f ), the ratio of the expansion ( ), the length of the tube ( l ) and the heat transfer condition, has been carried out on the improved experimental system. the results were drawn as the following : the refrigerating efficiency will be heightened by augmenting when is in 0. 0405 to 0. 1842 ; the highest cooling efficiency will be
實驗考察了有關因素對製冷效率和最佳射流頻率（ fopt ）的影響並進行了理論分析，結果表明，在= 0 . 0405 ~ 0 . 1842范圍內，製冷效率（ ）隨的增大而提高;隨射流頻率（ f ）的變化出現多個峰值，在本文實驗參數范圍內下，第二個峰值點的效率比第一個峰值點高;隨著膨脹比（ ）的增大，和fopt都略有增大，且低下的增幅比高下的大;強化管外換熱，可使fopt降低、明顯提高。 -
Pulse jet is the need of gas charge and exhaust for pressure wave refrigerator, and it also has some important influence on the performance of pressure wave refrigerator
脈動射流既是壓力波製冷機實現充、排氣功能的需要，也會對製冷機性能產生較大影響。
