幂函数

So using theory of power series to define and study function is an effective method of deal with question of function.

因此，用幂级数定义和研究函数是处理函数问题的一种有效的手段，并能给问题的解决带来一些方便，但是，幂级数只是函数的一种表示形式，只有与函数的其他表示形式相互协调和补充，才能真正简洁有效地处理函数问题。

It is found that the function relationship is affected by initial enrichment, cooling time and burnup range. The function relationship is also affected by irradiation history while the cooling time is shorter than 2 a.

发现幂函数关系中的系数受初始富集度、冷却时间、燃耗范围的影响；如果冷却时间大于2 a，这个关系不受辐照历史的影响；如果冷却时间小于2 a，这个关系受辐照历史的影响。

The characteristic temperature was corresponding to the maximum value of gelling activity energy.

对实验数据的分析表明，特征温度与原油经历剪切过程的粘性流动熵产呈幂函数关系，并据此拟合出相应的经验式。

Based on the measurements on 770 cage-cultured large yellow croakers, the relations between fish body width, length and their weight have been analyzed by means of regression equation.

对770尾网箱养殖大黄鱼的生物学参数体宽、体长与体重进行测定，运用幂函数拟合方法获得体重与其他两个参数的关系方程。

The average heat transfer and friction factor results from experiments can be well correlated by power law equation.

实验得到的通道平均Nu数及通道阻力系数均可用Re数的幂函数来表示。

During the prior fatigue life, fatigue damage induces a very small stiffness reduction value that always may be neglected. In the final fatigue life, the stiffness reduction evidently minishes following the power function.

在疲劳寿命前期，疲劳损伤对复合材料层板产生的刚度降变化很小，可忽略不计；在疲劳寿命后期，刚度降则按幂函数变化显著减小。

The effect of solidgrain diffusion was reflected by f0. The core diffusion could be excluded by minishing theparticle scales, but the solid grain diffusion could not.

在常见幂函数形式的速率方程中引入修正系数f0体现了固体扩散对反应的影响，说明减小催化剂粒径，只能排除孔扩散的影响，并不能排除固体扩散对反应的影响。

Experiments were carried out under greenhouse condi- tions to measure the growth rate of mycelia and uredia in leaf tissues.

结果表明，接种后48小时到192小时，菌丝体在叶片组织内扩展长度与时间里幂函数回归关系，慢锈品种是Y=0.0879X~(1.3459)；快锈品种是Y=0.1205X~(1.3859)。

The relationship between the breakage volumetric strain and the relative breakage can be fitted by a power function.

The result of wind tunnel showed the rate of soil erosion increases with the increasing of wind velocity by the power function.

风洞试验的结果表明，风速越大，风蚀越强烈，二者之间表现为幂函数的变化关系，18m／s是风速由轻变重的一个转折点。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
