By analyzing and predicting the microclimate in greenhouse in typical weathers, the conclusions are that high temperature with low humidity weather and high temperature with high humidity appear one after the other. the measures are proposed as the followings : to the former, it should be taken to decrease the temperature with soppy shade - fan or spray inside or outside ; to the latter, it should be taken to enlarge the ventilation area, to fit spray apparatus at the top of roof outside, to adopt havelock outside instead inside, to coat the roof white, etc

E was reclining upon soft downy cushions, covered with blue satin spotted with silver ; her head, supported by one of her exquisitely moulded arms, rested on the divan immediately behind her, while the other was employed in adjusting to her lips the coral tube of a rich narghile, through whose flexible pipe she drew the smoke fragrant by its passage through perfumed water. her attitude, though perfectly natural for an eastern woman would, in a european, have been deemed too full of coquettish straining after effect
那是一間類似婦女休息
室的房間,圓形的,天花板由玫瑰色的玻璃嵌成,燈光由天花板上下來,她這時正斜靠在帶銀點兒的藍綢椅墊上,頭枕著身後的椅背,一隻手托著頭,另外那隻優美的手臂則扶著一支含在嘴裏的長煙筒,這支長煙筒極其名貴,煙管是珊瑚做的,從這支富於彈性的煙管里,升起了一片充滿最美妙的花香的煙

At that hour of the night the narrow, damp well of a court, with its pestiferous water closets, its fountain, its back view ot the kitchen stove and the collection of plants with which the portress used to litter the place, was drenched in dark mist ; but the two walls, rising pierced with windows on either hand, were flaming with light, since the property room and the firemen s office were situated on the ground floor, with the managerial bureau on the left, and on the right and upstairs the dressing rooms of the company
這時候,狹窄的院子很潮濕,乍看上去像一口井的井底,周圍是臭氣熏人的廁所,水頭,廚房的爐灶,還有女門房胡亂堆放在那裡的草木。這一切統統籠罩在黑色煙
霧之中然而,開在兩堵墻上的各扇窗戶裏面卻燈火輝煌。樓下是存放道具的倉庫和消防處,左邊是辦公

Where customers never seemed to enter. then there were two or three upholsterers, deep in dust, and a smoky, sleepy reading room and library, the shaded lamps in which cast a green and slumberous light all the evening through. there was never anyone in this corner save well - dressed, patient gentlemen, who prowled about the wreckage peculiar to a stage door, where drunken sceneshifters and ragged chorus girls congregate
這里是游藝劇院的走廊和聖馬克走廊的交匯處,光線暗淡,店鋪里黑洞洞的,有一家無顧客光顧的鞋店,幾家傢具上積滿灰塵的傢具店,還有一間煙

According to the experimental data of droplet size 、 particle spectrum range 、 droplet cone shape 、 flow rate 、 cover area and cover area rate which obtained through changing the pressure of power sprayer and the nozzle diameter in greenhouse , this paper made comparative analysis on atomizing performance in same pressure and different nozzle type between same nozzle type and different pressure. the conclusion is that : the ejection rate and the droplet cone shape change with the variation of pressure and nozzle diameter , average particle diameter decreases obviously and particle quantity increases obviously with the increase of pressure and decrease of nozzle diameter. these results will lay experimental foundation for precise spraying 、 low pollution and highly effective operation
