sub-arable layer

The Upper Triassic Formation is sub-abysmal basinal facies deposit in the south and north depressions. A black shale layer developed.

上三叠统在南、北坳陷为次深海盆地相沉积，发育一套黑色页岩烃源层；

In the new method, sub band features and full band features are extracted in different timescales, then combined at probabilistic layer.

新方法在不同的时间尺度下分别进行子带特征提取和全带特征提取，并分别进行识别，然后在识别概率层相结合得到最终识别结果。

Hardness measurements identified that the relationship between the yield strength ( one-third of hardness) which increased with decrease of layer thickness for Cu/ Ni multilayers and single layer thickness at sub-micron length scale& could be described by the Hall-Petch ( H-P) formula for dislocation pile-up.

结果表明，当膜厚在亚微米范围内时，Cu/Ni多层膜的屈服强度（为硬度值的1/3）与单层膜厚之间符合基于位错塞积模型的Hall-Petch（H-P）关系式；
