孔径比 meaning in English

apertuer ratio
aperture ratio

Ratio of the pole spacing to the bore diameter of the pole pieces
极靴的间距与孔径比
Ratio of lens aperture
透镜孔径比
From sem of the polymer , we can found that , the polymer containing no dbp made by solvent of nmp had more and large pores than solvent of dmac , so it had larger liquid uptake and higher ionic conductivity
从sem测试图上也可以看出,不含dbp时,溶剂为nmp条件下制备的聚合物膜孔径比溶剂为dmac时大,孔隙多,吸液率大,离子电导率高。
Abstract : on the basis of the general chromatography rate model , the effects of bi number , number , mass transfer pel number , particle diameter , injection and ratio of solute diameter and pore diameter on the chromatographic peak of taxol and the separation of taxol and cephalmonnine were simulated with computer . the essential factors affect on the chromatographic process of taxol and cephalmonnine were obtained and a more useful theory was provided to direct the chromatography separation of taxol and cephalmonnine
文摘:根据建立的液相色谱普遍化速率模型，模拟了比渥数、数、传质彼克列数、粒径、进样量和溶质分子直径同多孔粒子孔径比对紫杉醇色谱峰峰形和紫杉醇和三尖杉磷碱色谱分离度的影响，获得了控制紫杉醇和三尖杉磷碱色谱过程的主要影响因素，从而为紫杉醇和三尖杉磷碱的色谱分离提供了更好的理论指导。
