fluctuation rate meaning in Chinese
波动率
起伏率
Examples
- Speed fluctuation rate
转速波动率 - The tooth shape of gear pump has important influence on machining and characteristics of pumps , such as flow rate , fluctuation rate and noise etc . first , the working principle of tatsuno combined pumps is analyzed in this article
齿轮泵的齿形对泵的加工、性能（如：流量、脉动率、噪声）等有很大的影响。本文首先分析了进口tatsuno组合泵的工作原理，并进一步分析了其采用一对双圆弧齿轮的优缺点。 - Although the flux per revolution of the optimized pumps is a little smaller than that of tatsuno combined pumps , other characteristics , such as fluctuation rate , maximum pressure angle and velocity fluctuation rate etc , are much better . the methods to cut gears are proposed in the theory for the practical produce in the future
虽然，在体积相等的条件下，优化出来的外圆弧包络线内啮合齿轮泵的排量略小于tatsuno组合泵的排量，但其它性能（如：流量脉动率、最大压力角、速度波动量）都更优。 - The research work in this paper follow four steps : define warning situation , seek warning sources , analyze warning omens , foretell warning degree . first , we define the grain price fluctuation rate as situation indictor and its warning line in a systematic way . second , we analyze the factors that influence grain price and divide them into eight categories which are product cost , grain supply , grain demand , real value of currency , market circulation , national policy , international factors and other factors
论文依照明确警情、寻找警源、分析警兆、预报警度四个步骤逐步展开研究，确定粮食价格的波动率作为粮食价格的警情指标，并用系统化方法研究了粮食价格的警限，系统分析了粮食价格的警源，把之归纳为八类因素。 - Seasonal dynamic model is introduced to analyze and evaluate tianjin raw water quality of luanhe river during 10 years for the first time , and so does for huanghe river during 4 years . based on these historical data , some long - term trend function of water quality items is got , by which seasonal fluctuation rate ( s c ) and seasonal dynamic trend of water quality items are computed . for the first time , clustering analysis is introduced to divide tianjin raw water into different levels
首次采用季节变动模型对天津市滦河水源10年的水质情况和黄河水源4年的水质情况进行了分析评价,得出各个水质指标的长期趋势项回归方程,根据趋势模型和各水质指标的历史数据求出季节比sc ,在各个指标的季节平均值和对应的季节比( sc )的基础上,得到了各个水质指标的季节变化趋势值。
