對外部空間,與縫隙腔體區域一樣認為場量與z無關,對所有場量做z方向的fourier變換,得到譜域上的一系列去耦合的二維方程。According to the experimental parameters of mpt, the main performance parameters of different propellants have been given by engineering performance computation under designed and working states, which has great importance for the experimental research and the future work. 2. for helium and argon, the factors which influence on mpt ' s vacuum steady work have been discussed such as the material of microwave tie - in, the distance between the probe and inner - conductor, the position of the inner - conductor, the input power of microwave, the mass flowrate of propellant and the vacuum pressure of environment, and the influence has been discussed of the microwave power and the mass flowrate of propellant on the pressure of the resonance cavity, thrust, reflected power and the temperature of the resonance cavity
論文的工作和新見解主要包括: 1在設計狀態和工作狀態下,根據mpt的實驗參數,對mpt使用不同工質時的性能進行了工程估算,這對mpt現階段的實驗研究和今後的研究有重要的指導意義; 2對于he 、 ar推進工質,討論微波的接頭材料、探針與內導體的間隙、內導體的位置、微波的輸入功率、工質的質量流量以及環境真空度對mpt真空啟動和穩定工作的影響,並探討微波的輸入功率、工質的質量流量對諧振腔壓強、推力、反射功率以及諧振腔溫度的影響; 3對于n _ 2 、 h _ 2 、 nh _ 3 、 h _ 2o推進工質,主要討論與he 、 ar工質不同的特性,並從長遠的眼光和工程應用的角度,認為其可行性不容置疑,潛在優勢不可忽略,是未來mpt應用的主流推進工質。Roll mat - - - can be cut and fit into different types of cavity wall, can be installed into any position of the construction, especially the long and nonblocked area, such as the roofing of metal building ; the slot of power lines, water pipes
卷氈- - -經切割可以用於任意尺寸的墻體空腔,安裝于建築的任意部位,特別是長而無阻塞的區域,如鋼結構屋頂;電線管、水管通過的槽隙等。Unlike oil pumps for traditional industries, our dry pumps are specified for the use of semiconductor companies. the rotor of vacuum space is not sealed with oil, but with the application of the minute clearance and high - speed rotation. therefore, a special demand is laid on the precision manufacture techniques, assembly procedures and profile design of roots rotor
以乾式真空幫浦為例,在2001年2月第一臺賣出去以來,已賣出數百臺,本乾式真空幫浦等級屬於半導體廠專用乾式真空幫浦,不同於傳統產業使用的油式真空幫浦,旋轉轉子真空腔體內不用油去密封,而是用微小的間隙配合高速旋轉的轉子進行密封,因此特別講究精密加工技術精密組裝技術魯氏轉子線型設計。Secondly, this article studies the static working state of the labyrinth seals in steady flow, including the cavity the relative thickness between gear the proportion of cavity depth to cavity width various gears the level angle of gear the influences of helical gear angle and it ' s flowing direction
2 、研究迷宮密封在定常流動下的靜態工作特性,其中主要包括空腔數、齒間相對厚度、間隙與空腔寬度之比、空腔深寬之比、不同齒形、齒面傾斜角、斜齒傾角和流向等的影響。The hub leakage flows were modeled and calculated in two different ways : the flow fields inside hub axial gap were calculated together with blade passage flow in an integrated manner, and the leakage flows due to the hub axial gap were modeled as inlet boundary conditions
計算時分別採用了兩種模化途徑,即耦合求解轉子上游葉根間隙內空腔與轉子通道內的流場,以及求解將葉根同間隙模化為進口邊界的轉子流場。Considering the kinetic diameter of 2. 89a for a hydrogen molecule, the inner cavity inside the tubes, the interstitial regions of tube arrays and the empty space between tube walls are the hydrogen adsorption sites. thus, the high hydrogen storage capacity in cnts would be available
氫分子動力學直徑是0 . 289nm ,單壁碳納米管的中空管內腔和管束內的間隙孔以及多壁碳納米管的中空管和管壁間隙都可以作為儲氫的吸附位,因此碳納米管具有良好的儲氫性能。分享友人
