「空氣動力學」規定了由於繞流反作用在發射飛行器上存在的壓力場和載荷。But the temperature difference at the vertical direction in combustion chamber in lead column, that is said by operator, is over 60 ?. ( 2 ) according to the experiences in the practice, the second layer air and the second layer gas had a little effect of support burning, and the third air has little effect for combustion, and the power to drawing exhaust gas can only be adjusted in limited range. the problems, it is said above, restricted more advance of some kinds of technology and economy target in spelter refining in new jersey furnace
由於鋅精餾爐產量提高,一些問題開始暴露出來: ( 1 )燃燒室?舶要求溫度差不超過10 ,而從現場反映的情況來看,燃燒室上、中、下部溫度差已超過60 ; ( 2 )在生產實踐中,發現燃燒室第二層空氣、第二層煤氣作用甚小,第三層空氣失去助燃作用,廢氣出口的抽力可調范圍有限;以上這些問題在客觀上制約了精餾塔在鋅精煉中各項技術經濟指標的進一步提高。Main conclusions drawn from the analyses of calculating results are as follows : ( 1 ) the microwave absorption of atmosphere gas have obvious attenuation at the wavelengths for cloud detection, thereinto, the water attenuation effect changes greatly, so the 94ghz cloud detecting radar should have water vapor attenuation correction scheme. ( 2 ) when 37ghz and 94ghz radars detect clouds, the difference between the atmosphere and cloud attenuation and the large variety of radar reflectivity conduce the intension of the radar backscatter signals change. ( 3 ) for the thin cloud layer and low water content of cloud, 37 - ghz radar backscatter signals are not as good as 94 - ghz radar, that is to say that the 94ghz radar has better capability in thin clouds detection
本工作得出如下結論: ( 1 )大氣氣體的微波吸收在測雲波段產生明顯的衰減,其中水汽衰減效應變化很大;即將上天的空間94ghz測雲雷達必須有水汽衰減訂正方案; ( 2 ) 37ghz和94ghz雷達測雲,由於大氣和雲衰減不同和雷達反射率的很大差異,導致雷達回波信號強弱不同; ( 3 )對雲層較薄、含水量較少的雲,在不計雷達參數的情況下, 37ghz雷達回波信號不如94ghz測雲雷達,也就是說94ghz對薄雲有更強的探測能力;對雲層較厚、含水量大的雲,由於強衰減的作用, 94ghz雷達回波信號小於37ghz雷達; ( 4 )從大氣衰減的不利因素方面考慮,空間94ghz雷達測高層薄雲的效果最好;測低層薄雲時需要考慮氣體衰減訂正;因濃厚雲的強衰減作用,探測其中下部的能力大大減弱,不僅要進行衰減訂正,而且要藉助其他信息來反演整個雲層的含水量垂直分佈; ( 5 )為了獲得從極薄到極濃厚雲的垂直分佈探測能力,未來測雲雷達系統最好採用雙波長甚至三波長(如94 、 37和13ghz ) 。According to newton ' s third law of motion ? for every action there is an equal and opposite reaction ? air streaming out the back faster than the aircraft ' s speed will thrust the plane forward
依據牛頓第三運動定律,每個作用力必會產生一個等量而反向的作用力,因此當空氣以高於飛機的速度自引擎尾部流出時,便可將飛機向前推。Through the competition of ionization equilibrium of zno22 - and precipitation reaction, the nucleation and growth process of znse have been adjusted, and monodispersed znse semiconductor hollow microspheres are obtained. these microspheres were found to form through aggregation of small znse nanocrystals sizes of which could be finely tuned by temperature control. a novel gas - liquid interface aggregation mechanism was proposed and this idea might be generalized in other systems
以zno22 -陰離子提供鋅源,利用它在強堿性溶液中緩慢釋放出zn2 + ,並與se2 -之間的電荷排斥作用,成功地調節了反應動力學,獲得了尺寸和分散性都非常均勻的微米級znse空心球,並實現了空心球內部粒子尺寸的調控,提出了新穎的氣液界面團聚機理。The addition of mg reacts with al and sio2 then form mgal2o4 at the interface in the sicp / al composites ; it reacts with sio2 and produce mgo at the interface in sicp / al - si composites, the good metal - ceramic bond is achieved
當mg含量為1 . 0時,對復合材料的力學性能和微觀組織結構改善程度最大。另外發現mg與空氣中的氮氣反應生成的mgn _ 2對sic顆粒增強復合材料的浸潤性也有改善作用。分享友人
