zero layer

The experiments used a kind of fulgide photochromic material as the recording layer. Different combinations of the laser power and the write time were used with 4-level recording realized using high, medium, low and zero laser diode powers.

实验中采用俘精酸酐类光致变色材料作为记录层，使用不同的激光功率和写入时间的组合，由大、中、小3种幅值和零功率写入实现了4阶存储。

Firstly, stability of a hypersonic boundary layer on a blunt cone with small nose bluntness at zero angle of attack has been investigated and the transition location was predicted by the e-N method.

首先，研究了高超音速零攻角小球头锥边界层的稳定性特点，并用e-N法进行了转捩预测。

In this paper, an energy budget model with zero dimension, in which the annual mean global cloudness, surface temperature and atmospheric temperature in boundary layer are chosen as climatic variables, is proposed.
