exponent curve meaning in Chinese

指数曲线

The frequency analysis results show conclusions as follows : 1 . the relative valid spectral power is declined with the volume percentage of inclusions in terms of exponent curve and the tendency of negative direction is same to that of forward direction
当ly12铝合金细小夹杂物(小于0 . 16mm )的体积百分数从0 0 . 35时，在35 50mhz的频带范围内，超声波形的有效谱功率按近似指数曲线快速下降，沿相反方向检测时其变换趋势相同。
Due to the existing volatility , stochastic and dynamic properties of cash flow , this paper employs exponential smoothing method and moving average method to eliminate the effects of the stochastic factors , use the seasonal exponent to eliminate the seasonal volatility of the cash flow , the exponent curve and polynomial fitting curve to estimate the overall cash flow and also provides the calculating methods and identifying principle of the overall cash flow
由于现金流量的波动性、随机性、动态性等特性的存在，依靠单一方法无法科学、准确的预测现金流量。论文提出利用指数平滑和移动平滑的方法来剔除随机因素影响，利用季节指数来消除现金流量的季节波动，之后再利用指数曲线或者多项式拟合曲线来预测整体现金流量的方法，并给出了整体现金流量的计算方法和确定原理。
