軸向孔隙
英文
axial porosity-
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The derivation of the leakage flow rate formula of the special annular clearance between the piston and cylinder under condition of variable viscosity in the axial piston pumps was carried out. at same time, considering the questions of the eccentricity and the variable sealing length of piston friction pair, the modified coefficient of the calculation formula of the flow - rate of the leakage was given
在變粘度、柱塞偏心以及變密封長度條件下，對軸向柱塞泵中柱塞與缸孔之間的特殊圓環縫隙的泄漏流量公式進行推導，得到了該計算公式的修正系數； 6In view of the problems in the design of the large andmedium - sized indoor substations built by guangzhou power bureau in recent years, points for attention in the design of indoor substations are expounded in terms of ventilation, cable channel, reservation of hangers and space for transportation and installation, ground wire, lighting for the whole substation, etc
僅僅推力頭軸、孔存在間隙時，推力頭其它零件製造質量與安裝質量達到設計要求，是不會影響精確徑向定位的.爾王莊泵站9機組出現的環鍵與平鍵斷裂情況，可能不是由軸、孔間隙過大引起，而是其它尚未查明的原因With the data recorded by computer, the author studies the experiment progress in detail, which includes the development of pore press, strain, strength of the sand, etc. connecting the development of these phenomena with the development of stress path, the author finds new mechanism which can explain the phenomena in the experiment. what is more, according to the dynamic test of the sand, there appears a steady state at the last phase of the development of strain and stress path, in which the strength of the sand is studied because it is an important parameter in evaluating the stability of sand against liquefaction. secondly, the dynamic constitutive relation was studied through the dynamic tri - axial test
本文首先採用目前國內較先進的微機控制動三軸儀，利用其可以適時採集和儲存數據的優勢，對砂土的實驗過程進行了細致的分析，研究該過程中孔隙水壓力發展、軸向應變發展以及它們與應力路徑之間的關系，對飽和砂土的剪脹、剪縮和卸載體縮等多個方面進行了研究，探索了砂土的動力特性，分析了影響砂土抗剪強度的各種因素，這些因素既包括土本身的特性（土的密度、結構、級配、透水性以及初始狀態等） ，又包括動荷載的特徵（振動力幅值大小和振動頻率等） 。The pore air pressure gradually goes up with the developing of axial strain in the process of the dynamic torsional shear test of loess, but the pore water pressure hold the line or goes up a little in the last. the stress - strain dynamic constitutive relationship of intact loess and man - made loess show the hyperbolic model. there are some remarkable differences of strength and strain between unsaturated loess and saturated loess
研究結果表明：非飽和黃土在動力扭剪試驗過程中，隨著軸向變形的發展，孔隙氣壓力逐漸上升，而孔隙水壓力則基本保持不變或後期略有升高；原狀黃土和重塑黃土的應力應變本構關系呈雙曲線型；非飽和黃土和飽和黃土的強度及變形特性存在明顯差異；進而分析了含水量、固結應力和固結應力比對黃土動力特性的影響本文最後對非飽和土的有效應力計算公式進行了討論。分享友人
