detect water 中文意思是什麼
detect water
解釋
偵測水源-
Heamagglutination tests were applied to detect virus in allantoic fluid of chicken embryos which were infected by b95 gathered from the vaccinated chickens " cloacal and oral cavity. the results show that the virus may be detected from 2 days to 11 days after the chicken being vaccinated. the hi antibodies were measured by heamagglutination inhibition tests. there is no significant difference between the immunized and the control chickens which were fed in one case. chickens were immunized with b95 by different immunization meathods or with different vaccines by the same meathod. lt is demonstrated that eyedrop, drinking water, spray or muscle injection all can stimulate good effects, but eyedrop and spray seem to be the best meathods. b95 immunized chicken have relatively higher hi titers and it also can last for a longer time than others
但如果兩者相隔10天以上免疫， b95免疫不受h120的影響；如果同時免疫b95和h120 ，加大b95的免疫劑量也能獲得良好的免疫效果。用棉拭子采b95免疫雞口腔、泄殖腔的分泌液，檢測其中病毒的存在，結果免疫后2 11天雞口腔和泄殖腔中均有病毒的存在，說明b95免疫雞帶毒時間長。研究結果表明， b95具有不受母源抗體干擾、 hi抗體產生快、水平高、持續時間長、同居擴散性強等特點，因此b95是一株優良的、具開發前景的新的新城疫疫苗株。 -

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 ） 。 -
