说明：  通过把分散在时间轴上的离散数据看成一组连续变化的序列，采用累加和累减的方式，将灰色系统中的未知因素弱化，强化已知因素的影响程度，最后构建一个以时间为变量的连续微分方程，通过数学方法确定方程中的参数，从而实现预测目的。(By regarding the discrete data scattered on the time axis as a series of continuous changes, and adopting the way of accumulation and subtraction, the unknown factors in the grey system are weakened, and the influence degree of the known factors is strengthened. Finally, a continuous differential equation with time as variable is constructed, and the parameters in the equation are determined by mathematical method, so as to achieve the prediction purpose.)

竞争性自适应重加权算法（CARS）是通过自适应重加权采样（ARS）技术选择出PLS模型中回归系数绝对值大的波长点，去掉权重小的波长点，利用交互验证选出RMSECV指最低的子集，可有效寻出最优变量组合。(The competitive adaptive weight weighting algorithm (CARS) uses adaptive heavy weighted sampling (ARS) to select the wavelength points with large absolute value of the regression coefficient in PLS model, remove the wavelengths with small weight, and use interactive verification to select the lowest subset of RMSECV, which can effectively find the optimal combination of variables.)
