Primary culture of rat preadipocyte were prepared from the epididymal, inguinal and perirenal the fat pads of male normal, healthy, 15 - 20 days sprague - dawley rats. the preadipocyte grew better under the condition of 37, 95 % humidity, 5 % co2, ph 7. 0 - 7. 2, centrifuged at 1000r / min, m199medium, and 10 % fetal bo vine serum, seeded at a density of 4 l04, 5 l04, / cm2. oil red o staining was the special method to distinguish adipocyte from other cells, gimsa and he could determine the stage of the adiopcyte differentiation through the number of lipid drop, size and the position of the nucleolus of the staining fat cell
經過多次實驗，確定本實驗室大鼠前體脂肪細胞的最佳培養條件是：溫度為37 ，濕度為95 ， co _ 2濃度為5 ， ph值為7 . 0 7 . 2 ，離心力為1000r / min ，培養基為m _ （ 199 ）培養基，胎牛血清濃度為10 ，合適細胞接種密度為4 10 ~ 4 、 5 10 ~ 4個/ cm ~ 2 ，染色結果表明：油紅o染色是鑒定脂肪細胞的特異方法， gimsa和he染色可根據不同區域染色程度、著色差別判斷細胞核的位置及脂滴大小、多少，觀察大鼠前體脂肪細胞分化過程中的形態變化，進而確定脂肪細胞的分化階段。 -
But for real microfiltration, the distribution of shear stress on the membrane of the module with outside helical flow would have benefit to make smaller number of particles deposit on the membrane. ( 2 ) by means of orthogonal test and regression method, four new models, trans - membrane pressure model, flux model, trans - module pressure drop model, and efficiency model, were established, which roundly describe the performance of outside helical mf by depicting the flux, energy loss, and handling capacity simultaneously
（ 2 ）採用正交回歸實驗，在無顆粒沉積的理想情況下，建立基於層流數值解的膜器跨膜壓力損失模型、過濾通量模型、過膜器的壓力損失模型和膜器過濾效率模型，首次從通量、能量損失及膜器對料液的處理能力等三個方面，更全面地對外旋流方式下的微濾過程進行了描述。 -
In the third chapter, the method and choosing principle of the test system component at first were brought out. the component of test device was introduced. and then, the characteristics, such as strouhal number, vortex street strength, vortex street stability and pressure drop coeffi
縱觀全文，本文成功地將cfd技術和實驗流體力學方法應用於新型雙鈍體渦街流量計的研究，並對旋進旋渦流量計的流體振動特性和抗干擾方法進行系統研究，提出了旋進旋渦流量計抗干擾設計的新方法。
