The field-flow classification deposition is a new molding technology which can overcome the traditional disadvantages such as multi-preparation to the preparation of great area of separation membrane with no defect.

流体过程分级沉积制膜技术可以克服传统制膜的缺点,是一种可以大面积制备膜层厚度可控、膜层无缺陷的一次成形技术。

By dividing the fiberglass filter into several layers with different mass thickness, the deposition distribution of α particles sampled in the filter is measured and the relation of the deposition with mass thickness is obtained.

对采样在玻璃纤维滤纸上的α气溶胶粒子进行分层测量,得出α粒子在滤纸中随质量厚度的沉积分布规律,进而求得了沉积分布函数。
