In this paper the floral ontogeny and the ovary development of rivina humilis l. were observed. the results showed that ( 1 ) the tepal primordia initiated in 2 / 5 spirals. the abaxial one initiated first, then the adaxial one, finally the lateral two initiated nearly simultaneously. the third one initiated on the position near the first tepal, and there is a gap between itself and the second tepal. ( 2 ) the 4 stamineal primordia initiated in one whorl at the same time. ( 3 ) the carpellary primordium initiated from the abaxial side of flower primordium ; the carpellary primordium grew upwards and towards axis after it was formed, therefore an elliptic orifice was formed at the adaxial position of ovary, which was the remainder of the mouth of ovary before the ovary was fused completely. with the ovary maturing, the orifice was narrowed because of the ovary growth, at last fused completely. the gynoecium is composed of a single carpel. ( 4 ) in the series developmental sections of ovary, the ovular primordium was initiated on the adaxial meristem when the mouth of ovary was formed
對數珠珊瑚的花器官發生和子房的發育過程進行了觀察.結果表明: （ 1 ）數珠珊瑚花被呈2 / 5螺旋狀發生，遠軸側的1枚先發生，其次為近軸側的1枚發生，最後側方的2枚花被幾乎同時發生，第3枚花被在靠近第1枚的位置發生，第2枚和第3枚之間有1個空隙; （ 2 ） 4枚雄蕊是同時發生的; （ 3 ）心皮發生於分生組織的遠軸側，心皮原基形成后，向上向軸生長，在子房成熟前在近軸側非正中位形成1個孔，該孔為心皮最終愈合前的殘跡，到子房成熟時，因子房的生長孔被擠壓縮小，在進一步的生長過程中愈合.子房由1枚心皮構成; （ 4 ）從子房發育過程的切片看，該植物的胚珠是在子房發生后不久發生的，子房上的圓孔形成時，從近軸側的分生組織發生胚珠原基，由胚珠原基分化出珠被與珠心 -
Sgk - b250 plastic pipe belling machine attribute semiautomatic opportunities for the single - use. such models use infrared heating, molding method adopts expand the headers to finalize the design, orifice size precise shape. the control panel don ' t have the conversion switch to control over the type of solvent for expansion socket ( vertical ) and ring - for flexibility expansion socket ( r ). expanding way is very easy choice and technics adaptability is strong, the main electrical control components are imported, system performance is stable and reliable
B250塑料硬管擴口機，屬半自動型作單機使用，擴管時管材由人工搬至擴管工位：這種機型採用紅外線加熱方式：成型方式均採用擴管頭定型方式，管口成型尺寸準確：該機型在控制面板上沒有擴溶劑型承插口（直口）和擴彈性密封圈型承插口（ r口）的轉換開關，擴管方式選擇十分方便，工藝適應性強：主要的電器控制元件均採用進口元件，系統性能穩定可靠。 -
The break was assumed to be a single tube double - ended and three - tube double - ended shear break. the diameter of the break orifice is 0. 876mm and 1. 518mm respectively. the characteristic responses of main thermal - hydraulic parameters, such as primary pressure, secondary pressure, break flow rate, pressurizer level, secondary side level of steam generator and so on, were presented in this thesis
試驗再現了核電廠蒸汽發生器單根傳熱管雙端斷裂事故和三根傳熱管雙端斷裂事故發生后的熱工水力現象，給出了事故過程中一次系統壓力、二次系統壓力、破口流量、蒸汽發生器二次側水位、穩壓器水位、元件表面溫度等主要參數的瞬態響應。
