中文说明：
针对发酵过程中生物参数难以实时在线测量的问题，建立了用于生物参数状态预估的支持向量机软测量模型。
English Description：
In order to solve the problem that it is difficult to measure biological parameters on-line in real time in fermentation process, a soft sensing model based on support vector machine (SVM) was established for state prediction of biological parameters.
