In the present work, we educed the systematic energy functional of the binary lipid membrane model. And based on the phase kinetics of continuous systems, we established the governing equations for the phase separation in binary lipid membrane under stationary shear flow. Then, by means of the cell dynamical system approach, the equations were numerically solved, intuitively giving out the domain morphologies and membrane shapes.

Aeruginosa and S. quadricauda in HAC were lager than in HA without reference to pure or mixed culter. It indicated that the growth of M. aeruginosa and S. quadricauda need HCO3(superscript -) as carbon source to balance its C:N:P ratio. Cyclotella sp. could not survive in HAC. M. aeruginosa and S.

铜绿微囊藻与四尾栅藻在HAC中纯培养和共培养的生物量K和最大增长速率r均远大于在HA中，表明这两种藻的增殖需要HCO3作为碳源平衡胞内营养平衡；小环藻不能在有HCO3的培养基中生存。

The growth inhibiting rate of T24 cell lines were detected by MTT methods, apoptosis of cells were detected by flow cytometry, the mechanism of apoptosis was analyzed by detecting the protein expression of Bcl-2, Bax, Caspase-9, Caspase-3 and cytoplastic protein Cytochrome C. 4 We injected live T24 cells into the subcutaneous space of nude mice and successfully built up the animal model of bladder carcinoma. The effect of CS-PAA-EPI polymer magnetic microspheres targeting chemotherapy was investigated by HE staining, TUNEL ,tumor weight and volume inhibition rate. Results: 1 TEM revealed that the CS-PAA polymer magnetic microspheres were regular spherical shape,the average diameter was 80nm in dry condition. By controlling the pH value of the medium,polymers had positive or negative zeta potential. VSM showed the CS-PAA polymer magnetic microspheres had superparamagnetic. The diameter of CS-PAA-EPI polymer magnetic microspheres were 200nm in solution by DLS examining,the embedding ratio was 20%,the EPI loading rate was 15%, which was higer than reported in other articles. 2 Raw eye observation found that the rat"s bladder of treatment group was brown color,which meaned the aggregation of iron particles, compared with the control group, iron stain found iron particles were assembled in rat"s bladder of the treatment group, the amount of iron particles in liver and spleen were less obviously.
