分数

In such a situation, mass fraction probability density function model is an appropriate method to approach the reaction phenomena.

在这样情况，许多分数可能性密度函数模型是接近反应现象的一个适当的方法。

The process of producing low-carbon aluminium killed steel using new deoxidant in the steelmaking plant of Baotou Iron and Steel Co was introduced.

介绍了包钢炼钢厂小方坯连铸机开发生产新钢种以及转炉采用新型复合脱氧剂生产低碳铝镇静钢的工艺路线，采用新型工艺路线及脱氧剂脱氧合金化后，Al收得率平均提高1倍以上，钢中氧的质量分数控制在10×10-6~50×10-6，低碳铝镇静钢的炼成率达99%以上，铸坯质量合格

It is important to note that the classical definition of fractional derivative in Eq.

但必须注意的是，经典的定义，分数导数在情商。

And if I've made a mistake in determining the grade I'll be sure to correct it.

如果我真的算错了你的分数，我会改过来的，别担心。

The left ventricular internal dimension at end diastole, interventricular septal thickness at end diastole and left ventricular posterior wall thickness at end diastole were measured in the parastemal long axis view by transthoracic two-dimensional echocardiography, and to calculate left ventricular ejection fraction with Teichholtz formula and left ventricular mass with modified Devereux formula, left ventricular mass index=LVM/body surface area. From the apical four chamber and two chamber view, the basical segment and middle segment of interventricular septal, left ventricular lateral wall, anterior wall and inferior wall were obtained by tissue Doppler imaging, Regional left ventricular relaxation asynchrony index was calculated.

应用二维超声心动图在胸骨旁左心室长轴观测量左心室舒张末期内径、室间隔和左心室后壁舒张末期厚度，采用Teichholtz公式计算左心室射血分数，采用Devereux校正公式计算左心室心肌质量，左心室心肌质量指数=左心室心肌质量/体表面积；在心尖四腔心和心尖两腔心切面，应用组织多普勒成像获取室间隔、左心室侧壁、前壁和下壁的基底段和中间段8个心肌节段沿左心室长轴运动的速度频谱，测算左心室局部心肌松弛不同步性指数(regional left ventricular relaxation asynchrony index， AI)；在心尖四腔心切面，应用彩色M型多普勒超声心动图测量左心室舒张早期血流传播速度。

And if the rotational angle is changed,only a diagonal matrix should be recomputed.

并且在改变分数阶幂时不需重新计算整个过程，只需计算一个对角矩阵。

Limitations of this study include possible loss of study power resulting from dichotomization of each of the 5 factors; only 1 baseline measure for each factor; and lack of inclusion in the combined score of all possible lifestyles, occupational exposure, or medical history that could be risk factors for pancreatic cancer.

这项研究的限制包括源自於这五个因子二变项可能流失的统计力量；每个因子仅有一次试验前的评量；且缺乏合并所有可能是胰脏癌危险因子的生活型态、职业暴露或是医疗史分数。
