In this paper , we give a brief introduction to the helfrich elastic theory . to solve the helfrich equation under the physical conditions of vesicles , a taylor series method is introduced , which offers a unified method to reproduce the exact solution including the famous axisymmetrical constant - curvature surfaces and the biconcave shape solution 本文在簡要介紹了helfrich的彈性理論及膜方程的基礎上,開創性地引入taylor級數法,在軸對稱膜的邊界條件下,對helfrich膜方程以taylor級數法求解,統一地得到了目前已知的兩個特解:常平均曲率曲面和紅血球形狀解。

Red blood cells were imged by afm and the typical biconcave shapes were observed . the ultrastructure of rbc membrane was also gained . the morphological changes of red blood cell ( rbc ) membrane after the interaction of trichosanthin ( tcs ) were clearly observed by afm 對紅細胞進行成像,觀察到紅細胞雙面凹的典型特征,小范圍掃描觀察到了紅細胞膜表面的超微結構,在此基礎上研究了紅細胞與天花粉蛋白作用后紅細胞膜表面超微結構的變化,并對二者作用的機理進行了分析討論。

In most mammals mature erythrocytes are biconcave disks that have no nuclei 在多數哺乳動物中,成熟紅細胞呈雙凹面盤樣,無細胞核。
