幂

In the decimal system, positions to the right of the decimal point have negative powers.

在十进制系统中，对于十进制小数点右边的位，它的幂为负数。

Of course, both exponent and mantissa are encoded using a binary system rather than a decimal system.

当然，幂和尾数都是用二进制数系统来编码，而不是十进制数系统。

At many occasions they arise quite natu-rally.For example,they appear in the Iwasawa decomposition of the isometry group ofa non-compact Riemannian symmetric space.Also,every connected homogeneous Rie-mannian manifold of non-positive sectional curvature can be represented as a connectedsolvable Lie group with a left-invariant Riemannian metric.

它们出现在非紧致黎曼对称空间的等距群的Iwasawa分解中；任一非正截面曲率的连通齐性和黎曼流形可以表为带有左不变黎曼度量的连通可解李群等，带有左不变黎曼度量的幂零及可解李群的微分几何，调和分析和谱几何是重要的研究课题。

The degree of a polynomial is equal to the highest power of x in it; here it is 2 because of the x2 term.

一个多项式的阶与其中x的最高次幂相等；这里是2因为x^2项。

It was shown that the matrix suction decreased with the increase of the water content and density. The relationship among temperature, density, matrix suction and water content was exponential.

试验数据分析表明：基质吸力随含水率的增大而减小；基质吸力随密度的增大而增大：温度、密度、基质吸力与含水率之间符合幂函数的变化关系。

In order to study the stability of non-Newtonian fluid and its flow pattern discrimination method,the integral stability theory and local stability theory are applied to the concentric annulus flowing of plastic fluid and power-law fluid,then a relevant stability parameter expression of discriminating flow pattern is derived and set up in the paper.

针对非牛顿流体的稳定性问题及其流态判别的研究，将整体稳定性理论及局部稳定性理论应用于塑性流体和幂律流体在同心环空的流动中，建立和推导出相对应的判别流动状态的稳定性参数表达式。这些参数的临界值与牛顿液体流态准数雷诺数的临界值，同样具有与液体流变性无关的特点。
