  1. Based on the reseaching of lycoris leaf micro - morphology characters by sem scanning, light microscope viewing and using paraffin method in the article, we try to provide the proofs of experiment and the efffective characer indexes to discuss the system and evolution of the lycoris. we find these microscope characers through reseach are as follows : the arrangement type, density and the length of stoma ; the shape and length of the epidermal cells ; the ridge of epidermis ; the transverse shape of leaf ; the number of the vascular bundle ; the style of vessel arrangement of vascular bundle in the middle vein ; the layers of palisade tissue ; the ratio of the thicken of palisade tissue to that of spongy tissue ; the angle number of the middle leaf ; the type of ventilating cavity etc. these characters are different from those of species in lycoris, meanwhile these characters are similar to those of some species in lycoris. so these characters can be used as the character indexes for differentiating species and reseaching systematic evolution of lycoris ; we can divide lycoris into two subgenus by these characteristic indexes : the species of one subgenus are l. aurea ( l " her. ) herb, chinensis traub, l. caldweuii traub, l. anhuiensis y. hsu et q. j. fan, l. longituba y. hsu et q. j. fan ; the species of another subgenu s are l. houdyshelii traub, l. albiflora koidz.,

    研究結果表明:葉表皮的氣孔排列方式、長度、長寬比,脊的明顯與否,葉表皮上的顆粒紋飾的多少、大小,葉表皮細胞長度、長寬比、垂周壁形狀,上部葉柵欄組織細胞層數、葉的維管束數、葉中脈導管組成數目,氣腔類型,葉的脊部遠軸面的角數,葉緣的形狀等這些特徵在種間存在差異,同時,在有些種之間又有相似性;因此,這些特徵既可以作為區分種的證據,又是研究石蒜屬植物系統演化的性狀指標,根據這些性狀指標,可以將石蒜屬植物大致分為兩個亞屬:一是忽地笑、中國石蒜、短蕊石蒜、安徽石蒜、長筒石蒜,二是江蘇石蒜、乳白石蒜、石蒜、玫瑰石蒜、稻草石蒜;在兩個亞屬中其中有些種如忽地笑、長筒石蒜、中國石蒜的親緣關系則更近些。
  2. Energy - saving design of mine ' s ventilating fan

    大中型選煤廠集散式監控系統的設計與應用
  3. Simulation of the air flow inside a ventilating fan

    風機內空氣流動模擬研究
  4. There are many kinds of methods dealing with fresh air supplying, such as free fresh air supplying, fresh air sucking, independent fresh air supplying, heat recovery ventilating ( hrv ), etc. it was proved that ac equipment capability and iaq has a relationship with fresh air states in fan - coiling and fresh air system

    除了無組織的新風供應方式,住宅空調系統新風供應還有新風吸入方式、獨立新風供應、新風換氣機方式。風機盤管加新風系統中,新風處理到不同的狀態點,對空調設備負擔的負荷及室內空氣狀態都有影響,本文對各種新風處理狀態進行了分析。
  5. It is indicated that hrv has many advantages certified by theoretic analyze and engineering practices, such as fully ventilating, abundant fresh air supplying, energy saving, etc. comparing with independent fresh air supplying, hrv is supposed to cause potential problems, - in summer load of fan - coil units will be increased, and the wet operating mode will be aggravated, the indoor relative humidity will be increased

    新風換氣機供應新風是住宅空調系統較為理想的新風供應方式,本文通過理論計算及工程實踐表明採用,新風換氣機具有換氣充分、新風量保證、節能等優點。但與新風機組獨立供應新風相比,新風換氣機供應空調系統新風時,會造成夏季風機盤管負荷增加,濕工況加重,室內相對濕度有增加趨勢。
