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。Furthermore, this dissertation also gives a comprehensive analysis and comparison to the torque ripple factor, torque - current ratio and other aspects for pseudo - sinusoidal emf bldcm drived by 120 conduction mode, 180 conduction mode and self - synchronous svpwm mode respectively. the simulation and the experimental results indicate that self - synchronous svpwm method is more effective for minimizing the torque ripple without any expense of the torque - current ratio when the crest width of the back - emf waveform is less than 107 electrical angles

摻氣分流墩的增加,明顯地改善了階梯面上的壓強分佈,消除或減小了階梯凹角內和立面上部的負壓;由於摻氣分流墩使水流縱向擴散以及挑流落下后在階梯上的撞擊,使水流的摻氣濃度和消能率都得到較大的提高,降低了階梯面空蝕的可能性,特別是在大單寬流量時,這種效果更為明顯。In the light of the signals of roll angle and water level, we can control the air valve, and use this control method to simulate the controlled passively anti - rolling tank. simulation results indicate that this control strategy is feasible. the controlled passively anti - rolling tank can work in the wide frequency range
