葉簇生；葉柄長15 - 30厘米，基部密被鱗片，向上近光滑；不育葉片長約60厘米，寬20厘米，一回羽狀；羽片多數，互生或近對生，線狀披針形，最長者長達12厘米，寬約1厘米，頂端長漸尖，基部心形，邊緣有細密鋸齒；葉脈1 - 2次分叉，近中脈形成網眼；能育葉與不育葉相似，但較小，長約8厘米，寬約0 . 4厘米，下部滿布孢子囊。There are obvious differences between the small protected area and the nature reserve and we traditionally preferred to do researches on the climax forest communities of the nature reserve, and do less researches on the forest communities of the nature reserve which is being built up and resumptive. the studies on the ecological characteristics of mid - subtropical evergreen broad - leaved forest of the small protected area were of importance
生態保護小區與自然保護區具有明顯的區別，傳統上偏重於對自然保護區的頂極群落研究，對正處在重建和恢復過程的生態保護小區森林群落研究甚少，所以對生態保護小區中亞熱帶常綠闊葉林群落生態學特徵研究具有重要意義。The results suggest that 1 ) sannella dworakowska should be moved out from typhlocybini to zyginellini ; 2 ) eupteryx complex is a molophyletic group and should be placed in typhlocybini ; 3 ) farynala complex, eupteryx complex and linnavouriana complex were confirmed to be molophyletic respectively which is in accordance with the traditional views. before this study, 44 genera and 6 subgenera, 502species of typhlocybini are found over the world, of which 20 genera and 87 species are known in china
結果表明： 1 ）圓頂小葉蟬屬sannelladworakowska在嚴格合意樹上位於樹的根部而與小葉蟬族其它屬的共同分支平行，不屬于本族； 2 ）蒿小葉蟬屬組eupteryxcomplex為一單系群，屬于小葉蟬族； 3 ）傳統分類所提出的除小葉蟬屬組typhlocybacomplex以外的其他幾個屬組（蟠小葉蟬屬組farynalacomplex 、蒿小葉蟬屬組eupteryxcomplex和林氏小葉蟬屬組linnavourianacomplex ）為亞單系群的觀點成立。The result of attrition is that, where the areas of the whole leaves follow a normal distribution, a bimodal distribution is produced, one peak composed mainly of fragmented pieces, the other of the larger remains
磨擦的結果是，在葉面上服從正態分佈的地方就會產生兩種分佈方式，頂點上主要是小塊，其他的地方是小塊，其他的地方是大塊的地方。Within a short while, snowflakes began falling outside the bus window. the snow got thicker and thicker on the ground. when the bus drove by a huge lake in the suburbs, we saw many pointed rooftops and white conifers along the road
才一下子，窗外就開始飄雪，那雪越飄越厚，后來，車子開往市郊某個大湖，沿途有許多覆蓋著白雪的尖頂小屋與雪白的針葉樹，一幕接著一幕，彷若童話書上的聖誕雪景，每個人都看得心滿意足。Thus the resistance factor and vibration modes of the soil layer are obtained and used to analysis the pile response. by considering the interaction between the soil layer and the pile with boundary condition of continuity of displacement and equilibrium of force at the interface of soil layer and pile, the dynamic equilibrium equation of pile is solved and an analytical solution for the pile response in frequency domain is yielded, which is used to define complex stiffness and mobility at the level of the pile head. based on the convolution theorem and inverse fourier transform, a semi - analytical solution of velocity response in time - domain subjected to a semi - sine exciting force is given
首先通過引入勢函數方法對土體位移進行分解，從而將土體動力平衡方程解耦，求解得到了土層的振動模態和阻抗因子，然後利用該解以小應變條件下樁土接觸面上力平衡和位移連續條件來考慮樁土耦合作用，求解樁的動力平衡方程，得到了樁頂的頻域響應解析解、復剛度和速度導納，利用卷積定理和傅里葉逆變換，求得了半正弦脈沖激振力作用下樁頂速度時域響應半解析解。The blades require a relatively low wind speed, a little over 10 kilometres per hour, to start turning. at a wind speed of 20 kilometres per hour commonly experienced at hilltops and exposed places of hong kong, the generator is capable of generating 50 watts of electrical power, sufficient to support an automatic weather station
這些車葉不需太大的風速，即稍稍高於每小時10公里，便可轉動。以香港多處的山頂和當風地點來說，一般都有每小時20公里或以上的風速，風力發電機可產生50瓦特電力，足夠應付一個自動氣象站的需要。The plant looked quite ordinary, much like alfalfa. it had four leaves on each leafstalk, two larger ones at the apex and two smaller ones lower down, and all of the leaves swayed rhythmically to music, especially folk music
其實她長得其貌不揚，有點像苜蓿草，一個葉柄上有四片葉子，葉柄頂端生了兩片大葉，葉柄下端則生了兩片形狀相同的小葉。分享友人
