投入產(chǎn)出

The Chinese 6-sector computable nonlinear dynamic input output model and the method for determining its parameters are given in this paper. 給出中國六部門可計(jì)算非線性動(dòng)態(tài)投入產(chǎn)出模型的構(gòu)模原理，以及如何依實(shí)際數(shù)據(jù)設(shè)定模型參數(shù)的方法。

Based on kinetic principle and the Iaw of inputand output, we have studied the contarnination factors of agri-cultural Iands around a Iead and zinc metallurgical plant. 運(yùn)用動(dòng)力學(xué)原理和投入產(chǎn)出法則研究了浙江省某鉛鋅冶煉廠周圍農(nóng)業(yè)土壤中鎘的污染因素。
