幂

Therefore, in this paper, a newempirical creep model is proposed, in which the power function is used for shear stress-strain behavior and hyperbolic function is used forstrain-time behavior.

鉴于此，本文试图建立新的蠕变本构模型进行理论分析，即应力-应变关系采用幂函数，应变-时间关系采用双曲线函数。

Thus, modeling by 5 empirical equations showed that using hyperboloid and power function fitting the relationships are quite good.

鉴于此，选取5个经验方程进行建模，结果显示，对于胸径和CI、RCI、RC1、RC2间的关系用双曲线和幂函数方程拟合较为适宜。

Our work includes: 1 Different from general target recognition problems, L2 normalized samples are applied to HRRP-based RATR to deal with the amplitude-scale sensitivity problem, therefore, geometrically speaking, HRRP samples spread on a unit hypersphere.

考虑到用于识别的HRRP样本在2-范数强度归一化后都位于单位超球面上，针对于幂次变换后趋于Joint-Gaussian分布的HRRP数据，提出了一种改进的基于子空间近似的统计识别方法。

For such operations, the Ice run time uses a more aggressive error recovery mechanism than for non idempotent operations.

对这样的操作，ICE运行时会用一种比非幂等操作更积极的错误恢复机制。

Actually function-tree is an application of Boolean theory. Function-tree can be optimized by using absorptive law and idempotent law in Boolean algebra to remove redundant information.

功能树本质上可视为是布尔代数理论的一种应用，从而利用布尔代数的吸收律、幂等律来消除功能树中的冗余信息，对功能树进行优化处理。

This method can find CS according to the relationship among inputs and outputs implied in the incidence matrix, finally using Boolean absorption law, idempotent law, or prime law to get MCS.

具体方法是在关联矩阵中按行、列查找所表达的输入、输出关系，直到找到基本事件，并将对应事件按"与"、"或"关系展开，这样可以直接从关联矩阵中得出割集，再按照布尔吸收律、等幂率或素数法求出最小割集。

Theorem 2.6.1 Let e be a central idempotent of ring R.

Results Two new characterizations of regular rings are given.(1) If R is a left SF'-ring and R/Z is reduced, then R is strongly regular;(2) R is strongly regular if and only if R is a left SF'-ring whose every idempotent element of R is left semi-center and is LANE-ring.

结果 得到了SF'-环是强正则环的两个充要条件：(1)R是左SF'-环，如果R/Z是约化的，则R是强正则环；(2)R是强正则环当且仅当R是满足幂等元左半中心的左SF'-环，且R是LANE-环。

If it is finite and nonempty , then it must contain at least one idempotent.

如果它是有限和非空的，则它必须包含至少一个幂等元。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
