藥柱變形 的英文怎麼說

This is so because climbing plants are likely to encounter intensive - changing environmental condition during their growth ( especially change of illumination ). secondly, there is a large proportion ( 30 - 40 % ) of climbing plants which belong to dioecism, and hence a gap between male and female plants on morphology, biological characteristic, economic value and so on. this dissertation focuses on herbaceous climbing plants, perennial or annual species such as dioecious trchosahthes kirilowii maxin and dioscorea opposita thumb, and monoecious luffa cylindrical ( l ) roem, it attempts to discover how climbing plants adapted to various environments and the mechanism of adaptation from aspects of physiological and reproductive ecologies at present, due to overuse of chlorofluorocarbons ( cfcs ), the ozonosphere has become thinner and thinner, and the ultraviolet - b ( uv - b ) radiation has increased considerably

而攀援植物本身是一類理想的植物行為生態學研究材料：第一，攀緣植物由於受攀緣能力和支柱木資源的限制，在生長過程中通常要遇到強烈變化的環境條件（特別是光照） ；第二，攀緣植物中具有較高比例的雌雄異株類型，通常佔地區攀緣植物種類的30 40左右，不同性別的植物在形態學及生物學特性、經濟價值等方面存在一定的差距，因此，本文以雌雄異株攀緣植物栝樓（ trchosahtheskirilowiimaxim ） （葫蘆科多年生草質藤本植物）和山藥（ dioscoreaoppositathunb ） （薯蕷科薯蕷屬植物） 、雌雄同株異花攀緣植物絲瓜[ luffacylindrical （ l ） roem ] （葫蘆科一年生攀緣草本植物）為材料，試圖從生理生態學及生殖生態學角度揭示攀援植物如何適應不同生境及其機理。

It has a large region of application in solid rocket motor grain design and has made new improvements compared with other available codes. user can easily and rapidly build his initial grain shapes and then obtain geometric information of his design. according to the theory describeds in the paper, the regressions of the burning surface area and the pressure are obtainded

該系統擴展了固體火箭發動機裝藥的設計能力，用戶可利用它簡捷地構造出三維藥柱的初始形狀，並獲得設計所需的各個幾何參數，進而依據本論文提出的復雜三維藥柱內腔燃燒推移和燃面計算的方法，計算出燃面變化和壓強變化，得到推力隨時間變化的曲線，再依據這些計算結果進行再設計，直至達到滿意的結果為止。

The main work and achievements are summarized as follows : based on herrmann variational principle and the nearly - incompressible viscoelastic constitutive relation, a new type of viscoelastic incremental finite element method is presented. in this method, incremental arithmetic is applied to solving the hereditary integrals. it needs less memory space, has simple parameter matrix, and calculates stiffness matrix only once

主要研究內容如下：從herrmann變分原理出發，基於適用於近似不可壓縮材料的粘彈性本構關系，利用增量法處理遺傳積分，發展了一種粘彈性增量有限元方法，所需存儲空間較少，參數矩陣形式簡單，求解過程只需要形成一次剛度矩陣，適用於藥柱的結構計算，奠定了確定性分析基礎。

In the analysis ansys6. 0 is used. two grain fem modals are used to figure out the stress and strain under different load case, including inertial force in radius direction, inertial force in axis direction and colligating the two inertial force. last, the result is compared with the result of analytic method

在不同的受載條件下，求出藥柱應力場和變形，包括只受徑向慣性力，只受軸向慣性力及徑向軸向慣性力綜合作用下的應力應變分佈並與解析方法相比較，得出了較為合理的結果。

This developed method is suitable for srm grain with low modulus and large deformation

適于固體藥柱模量較低、變形較大的特點。

The transgenic plants ( to ) and untransformed control ones in normal greenhouse condition had no notable differences in morphlogy and pollen germination rate in vitro. however, treated with 150 mm 5 - fc, more than 90 % of transgenic lines showed pollen sterile to some extent, and the lowest germination rate was 3. 4 %, about 1 / 20 of that of the control. some transgenic lines had some changes in anther and stigma size, anther color, pollen number and quality

溫室栽培的轉基因煙草苗（ t _ 0 ）未噴5 - fc處理時，植株外部形態和花粉發芽率與未轉基因的對照沒有可見的差異，但用5 - fc （ 150mm ）處理后， 90的轉基因煙草的花粉有不同程度的敗育現象出現，最低花粉萌發率為3 . 4 ，是對照的1 25 ，同時少量植株還伴隨有花型，花藥、柱頭大小，花藥色澤，花藥內花粉的飽滿程度等的改變。
