指状孔 meaning in English

dactylopore

Support changed the structure of pvdf membrane : sponge tissue reducing and loosening , finger pore lengthening . the desalination properties of membrane were discussed through equipment of md . factors effecting on flux of distillation , desalination efficient , heat efficient were analyzed
实验结果表明，支撑体的加入在一定程度上改变了pvdf膜的形态结构，使得海绵状组织减少，结构疏松，指状孔变得贯通，与课题所设计的理想模型比较吻合。
On the basis of study on structure and mass transfer , ideal model of membrane structure was built up , in which skin layer should be as thin as possible ensure resisting water to pass though membrane ; finger pore should be as long as possible in the membrane ; proper pore size ; loose sponge tissue
首先对利用相转化法制备的微孔膜形态结构进行研究，确定传导阻力较小的理想结构模型，致密层在能阻止微孔被浸润的情况下尽可能薄；指状孔在膜厚方向所占比例尽可能大；孔径大小适宜；海绵状组织结构疏松。
