Compared with the previous method, the improved route can provide directly a spheroid form of immobilized lipase particles of which the size can be controlled by adding non-ionic surfactants during the preparation process so as to increase the recovery rate of enzyme as well as decrease the external diffusional restriction which can diminish the enzyme activity. The improved method can also alter the hydrophobicity and microstructure of the immobilized enzyme matrix by changing the molar ratios of different alkoxyl silanes so as to enhance the enzyme activity by a"surface active effect"and eliminating the internal diffusional restriction.

与前人的制备方法相比，改进的方法可直接制得球形的固定化酶颗粒，而且颗粒的大小可以通过在制备过程中加入非离子型表面活性剂加以控制，从而可以提高固定化过程的酶活回收率和减小外扩散效应对酶的表观催化活力的影响；改进的方法还可以通过改变原料硅氧烷的种类及配比来改变最终制得的固定化载体的疏水性质及微观结构，从而通过对脂肪酶的&界面活化&作用和减小内扩散效应提高固定化脂肪酶的表观酯化活力。

The plastic pot had better drainage and higher ODR, so the plant grown in plastic pot had higher growth performance and root vigor than that in fabric bag grown or in field. The growth performance and nursery quality of Alstonia scholaris plants in hard pot were similar to those in soft pot.

试验结果显示：黑板树之田间苗和织布袋苗的土壤氧气扩散速偏低，以致减缓苗木的生长；而塑胶盆具有较佳的排水性和土壤氧气扩散速，因此塑胶盆苗较田间苗和织布袋苗具较佳的生长表现和根系活。

湖南省委党校湖南行政学院，长沙410006中文摘要：技术扩散是解决软件产业技术落后的重要解决途径，并在扩散路径上呈现出&S&形特征。

RESULTS: Fluorescein concentrated cell presented extensively around micro-vessels after injection of both FA and FD. The speed of diffusion of FD in the brain was faster than that of FA. After FA injection, fluorescein concentrated image presented also around vessels, which developed to the distal along vessels, those in the cortex developed toward cerebral surface and those in the white substance toward ventral basicranial vessels of brain. The speed and distance were all bigger than the simple diffusion.

结果：注入FA，FD之后均可见微血管周围广泛分布荧光浓集细胞；FD在脑内扩散速度大于FA；FA注入后还出现血管周围荧光浓集影像，并沿血管通向远处，在皮质者通向脑表面，在白质者通向脑腹侧颅底血管，速度与距离均大于简单扩散。

The liquid diffusion coefficient is an extremely important parameter in mass-transfer processes. Benzylpenicillin potassium, benzylpenicillin sodium, ascorbic acid, amino acids and amino acid hydrochlorides are used widely as medicine and nutriment.

液相扩散系数是传质过程中非常重要的参数，青霉素、抗坏血酸、氨基酸及氨基酸盐酸盐作为广泛应用的医用及营养药物，对其在水中的扩散。。。

The water diffusion processes and the relationships between water diffusivities and soil water contents in typical meadow Calamagrostis angustifolia wetland soil in Sanjiang Plain were simulated by horizontal soil column infiltration method.
