  1. The study shows that the early and late seed rains of constructive tree species in evergreen broadleaved forest at chongqing simian mountain had no activity. the bigger the seeds of the species and the earlier or later the seeds of the species matured, the higher the proportion of the seed rain damaged by animals. the quantitative variation of seed rain, active seed rain and seed bank did not take place at the same time. at early time, the number of seed banks of castanopsis fargesii, lithocarpus glabra, quercus myrsinrefolia, castanopsis plasyacantha, cinamomum subavenium. which own more active seed rain increased by geomitric series. the seed banks of castanopsis orthacantha and schima argentea were small, only survived a short time, and did not sprout next year. the quantitative dynamics of seed banks and their increasing or decreasing rates were decided by the proportion damaged by animals, dying speed of seeds and their resistance to pathogens and adverse circumstances, and the state of seed germination

    對重慶四面山常綠闊葉林建群種種子雨、種子庫的研究表明,建群種早期和晚期的種子雨無活力;種子偏早或偏晚成熟及大籽粒的樹種,其種子雨被取食的比例大;種子雨、有活力種子雨、種子庫三者的數量變化不一致;有活力種子雨量較大的栲、石櫟、小葉青岡、扁刺栲、香桂等,其種子庫密度在早期以近幾何級數的方式增長,元江栲、銀木荷種子庫小,存在時間短,翌年無一年生萌發苗;種子庫數量動態、消減率動態決定於種子被取食的強度、種子衰老的速度以及種子對病菌、逆境的抗性和種子萌發的整齊性
  2. With the increasing light adaptive time, the length of rhabdom trended to be longer and proximal pigment trended to spread more widely, but the variation was smaller in full bright light and short wave ( blue ) light conditions than that in long wave ( red ) light condition

    藍光照條件下感桿束直徑和長度變化與全光照相似,但近端色素的伸展幅度以藍光下條件最大,紅光次之,均大於全(色)光照條件。復眼結構對短波光(藍光)的敏感性高於長波光(紅光) 。
  3. By analyzing and processing bountiful experimental data collected in short time, the curves of temperature variation of fast transient nucleate boiling are then drawn with wavelet analysis theory. also by setting up the mathematical model and applying the temperature variation curves to this mathematical model, heat flux density can be resolved

    利用數學方法? ?小波理論成功分離了快速數據採集系統中溫度信號和噪音信號,得到瞬態沸騰的溫度變化曲線;並通過建立數學模型、利用實驗所得的溫度變化曲線,求解出瞬態熱流密度。
  4. The gap fuel - rich propellant showed short ignition delay time, high burning rate, and sensitive to variation of gas generator pressure. the results also showed that some tmo, such as moo3 and 0203 can increase the burning rate of the gap fuel - rich propellant

    測試結果表明, gap貧氧推進劑具有點火延遲期短、燃速高、燃速對壓強敏感性強等優點,且某些tmo催化劑如moo _ 3 、 co _ 2o _ 3等可顯著提高gap貧氧推進劑的燃速。
