The recent studies in this field mainly include the following four aspects: the consumers' recognition of organic food; the consumers' attitude towards organic food; the consumers' purchase of organic food; the consumers' willingness to pay. The paper would review the recent domestic and foreign studies on the four aspects mentioned above,aiming to provide references to the researches in this field.展开更多

It has been preliminarily determined that 750 kV will be adopted as the next higher transmission voltage to the 330 kV being used. In consideration of the temporary slowing down of the growth of electric power industry in Northwest China and the advance of the.research work on nation--wide interconnection, the authors put forward their views on this problem.展开更多
