一種基於內充泡沫塑料薄壁方管的單殼舷側耐撞結構The present paper reviews the construction and constitutes of pollen tube wall, the migration of generative cell and vegetative nucleus, as well as the movements of organelles and secretory vesicles in pollen tubes
本文就細胞壁的結構及組成,生殖細胞和營養核的移位,細胞器以及分泌小泡的運動等方面作了較全面論述。Due to its complexity of the problem, the theories and experiment results obtained are discrepant, and some of them are even contrary one another. started from the influence by movement rules of small cavities and solid particles, the mechanisms of combined effect of cavitation and sand abrasion are study in this thesis from the aspect of the turbulent coherent structure near the wall. first, a dynamic equation is established for a single spherical bubble and single spherical sand under the non - turbulent coherent structure near the wall, and then a dynamic equation established under the turbulent coherent structure near the wall
首先從理論上推導出在典型湍流邊界層模式的非擬序結構下空泡與固體顆粒的近壁區運動方程,然後推導出湍流近壁擬序結構作用下的空泡與固體顆粒的近壁區運動方程,再將兩種不同條件下的的運動方程進行比較,指出湍流近壁區的擬序結構對空蝕與磨損的發生具有決定性的意義,即正是由於擬序猝發作用的存在,才使得空泡、沙粒對壁面的空蝕與磨損作用得以發生。In this experiment, three dead sheep from spa were been as materials to make histopathological and ultrastructural observation. the results showed the primary lesion was the resultant transformation of type ii epithelial alveolar cells. tumors were composed mostly of single layers of cuboidal epithelial cells arranged in an acinar pattern, but all rumors had areas where the tumor cells piled up, forming papillary projections into the alveolar spaces
本試驗以某羊場病死羊肺臟作為病料,製成病理組織切片,通過病理組織學檢查,結果表明:肺臟主要病變是肺泡細胞變為立方形或低柱狀細胞,這些細胞沿肺泡壁排列,突入肺泡腔內形成乳頭狀腺瘤結構;在氣管,支氣管腔內有灰白色泡沫狀液體,嚴重時使肺泡變為腺管狀等。Numerical results show that the bubble concentration distribution can be predicted by using the two - way coupling of the fluid and the bubble motion, and adding the wall lift force into the bubble motion equation, and the fluid velocity, turbulence intensity and shear stresses modified by the bubble motions can also be revealed
數值模擬結果表明,通過加入壁面升力和採用雙向耦合方法,可以較準確地預測氣泡濃度分佈和揭示氣泡流動對流體湍流結構的影響。Through comparison, it can be seen that the turbulent coherent structure near the wall influences directly the striking effect of the bubble and sand. a new proposal is put forward at the end of the thesis that the destruction caused by the combination of cavitation and sand abrasion can be mitigated by means of controlling the turbulent coherent structure near the wall
最後用有關的結論對過去的空蝕與泥沙磨損聯合作用的一些試驗觀測結果進行了定性的分析、評述,並提出通過控制擬序結構的發生以達到控制空泡、沙粒對壁面的沖擊作用是減輕磨蝕破壞的一條新的途徑。分享友人
