【正文】 management distance between enterprises(facilities), stimulate the enterprises to search for the drive of progress, which will be good for the promotion of advancing the technology and running management of industry and enterprises. Therefore, it is very necessary to municate the economic and technologic index in microcosmic level.Because of the big difference of the salt mine embedding situation, the brine exploitation between enterprises is not need to be pared, therefore it is not considered. Index should to be municated Quality indexQuality is the life of enterprises, and it is concerned by enterprises, consumers and government. Its good and bad not only lies on the quality standard and the requirement of consumers, but also depend on the technology and running management situation of enterprises(facilities). Therefore, it should be labeled as the municated index, and the index system should be ensured by standard and the requirement of consumers. Consumption indexThe high and low of the consumption directly determine the cost, which is concerned by enterprises very much, and it also determine the level of resource consumption and the degree of environment friendly, it is then concerned by government and country. Therefore, it should be labeled as municated index, and its index system includes brine consumption, electricity consumption, steam consumption and water consumption. The good and bad of its value not only lies on the technologic situation of enterprises(facilities), but also lies on the running management situation of enterprises(facilities). Efficiency indexThe efficiency directly decides the exerting effort of putting the facilities into function and the good and bad of some consumption, which is concerned by enterprises and investors, therefore it should be in the municated index. The good and bad of its value not only lies on the technologic situation of enterprises(facilities), but also lies on the running management of enterprises(facilities). Its index system includes “productive intensity”, “evaporation intensity” and “effective production hour of per year” etc.5． THE ISSUES NEED TO BE DISCUSSED The electricity consumption factor belonging to the index values which influences the productive intensity is not considered. For the form of flow speed which is the necessary heat exchanging condition of heat exchanger, it needs power consumption, and how to make it with good heat exchanging effect but with small electricity consumption? Can we set a productive intensity index which is evaporation water quantity per unit heat exchanging area, unit temperature difference and unit electricity consumption to describe the technology and running management situation of heater of evaporator. The count boundary of its value is the electricity consumption of circulation pump of evaporation crystallization and average effective heat exchanging temperature difference of evaporator of heat exchanger and the water quantity for evaporation from brine.
