thickening out 中文意思是什麼
-
Three types of cuticular thickening at the polar region of the guard cells are observed : slight cuticular thickening ; rod - shaped culicular thickening and rarely t - shaped thickening. with data obtained from the former research and personal observation, the cladistic methods were employed for the phylogenetic analysis of data and trees were rooted by out - group comparison using, the related genus kadsura. as result, a new system of the genus schisamdra michaux was reconstructed, and schisandra michaux was subdivided into 2 subgenus, 3 section, 2 series 10 species in this dissertation
整理有關五味子屬植物研究的資料，補充搜集近期發表的資料和本人研究所得數據，以種為基本單元，選擇近緣的南五味子屬（ kadsura ）作為外類群，採用paup4 . 0b4a軟體對本研究得出的性狀數據作分支分析，重建五味子屬的系統發育，修訂和補充五味子屬分類系統，在五味子屬下設2亞屬、 3組、 2系、 10種。 -
The method takes advantage of bezier curve to work out a set of blade profiles of centrifugal pump, using thickening law to thicken the profiles. then the pressure and suction lines of the blade can be obtained. it takes advantage of bezier surface to create pressure and suction surface and makes use of mdt software to create the three - dimensional blade entity
首先採用速度系數法計算得到離心泵葉輪的基本參數，再由b zier曲線生成一組葉輪葉片型線，按照加厚原理對型線進行加厚，得到正背葉片線，再採用張量積b zier曲面生成葉片正背面，由mdt進行三維實體造型得到葉片，從而得到流場計算區域的模型。 -
Abstract : an analysis on the damage of flame arrester of oil tank has been made from its structure as well as daily care. countermeasures against its disability have been presented, that is, casting the two semi - casing into one piece, leaving out the intermediat flanges, thickening the casing, and increasing the casting round - angle between the flanges and casing. in this way, the strength of casing can be enhance and local stress will be decreased. in addition, in order to enlongate the service life, the operating frequency of flame arrester should be properly reduced in daily care
文摘:從設計結構及維護保養的角度分析了儲油罐阻火器損壞的原因，並提出了相應的改進措施，即在結構方面可以將阻火器外殼鑄為一體，省去中間法蘭，增加殼體厚度，加大法蘭與殼體之間的鑄造圓角，以增加強度減少局部應力:在維護保養方面，應適當減少操作次數，延長阻火器的使用壽命。
