查询词典 instability constant

When the torsion field is static, its strength is proportional to the gravitation constant G times the Planck constant h, therefore, it is 10^27 times weaker than the weakest gravitation of the four forces, thus it was not taken seriously.

The results showed that food ingestion and frequency of the polecat in constant food patches were higher than that in the variable food patches and time of the polecat was the same between two patches during the training period. Only the frequency of the polecat in constant food patches was higher than that in variable food patches when the polecat was starved for 1 day. Its foraging pattern between the two patches was the same as that during the training period when the polecat was starved for 2 days. Meanwhile, the food ingest ion amount in the two patches was not affected by starvation, but the time and frequency of the polecat using the two patches significantly decreased when starvation increased.

研究结果表明，训练期实验中，艾虎对固定食物量斑块中的取食量和利用频次明显高于变化食物量斑块，而对两个斑块的利用时间基本相同；艾虎饥饿一天后对固定食物量斑块中的利用频次明显高于变化食物叠斑块，而对两个斑块的利用时间和取食量基本相同；艾虎饥饿两天后对两个斑块利用程度与训练期的结果相同：同时，艾虎在两个斑块中的取食量均与饥饿程度无关，而对两个斑块的利用时间和利用频次均随饥饿程度明显降低。

The logical system Qs is obtained from the pure predicate calculus by adding a binary predicate constant S which denotes the sanctions, an individual constant c denoting the state institutions, and some definitions of deontic modal words but not adding axioms or deducible means.

它以狭义谓词演算为基础，在其形式语言中添加专指"制裁"行为的谓词常项，添加专指"国家机关"这种法人的个体常项，添加规范词的定义，但不添加推演工具，就可次生出关于法律规范的逻辑。

The main achievements could be summarized as follows.1. The basic stress-strain characteristics and related physical mechanisms for sands under cyclic rotation of principal stress axes were investigated based on three kinds of drained tests including fixed principal stress axes, cyclic rotation of principal stress axes with magnitudes of principal stresses kept constant, and cyclic changes of principal stresses in both their axes and magnitudes. The main deformation behavior of sands with inherent anisotropy under cyclic rotation of principal stress axes with magnitudes of principal stresses kept constant was obtained in the following.
