Abstract: Based on the structural characteristics of the shell -type heat exchanger and plate evaporator, based on the high -efficiency horizontal tube spray -type membrane -proof evaporator, a new type of shell -shell reduction evaporator is developed. The theoretical analysis and experimental results show that the ellipse cavity beam is a new type of evaporator with an evaporation inner part. The evaporation speed is fast and the heat transfer efficiency is high.

Abstract: Metal pyrine can cooperate with organic alkaline pyriral, pyridine, etc. [1], while simple pyrine has no nature. This is because the transition metal pyrine has a plane structure and axial non -saturated. It is easy to form a combination with organic alkali, which enhances the ligand activity and provides spatial conditions and structural conditions that are conducive to response. This article studies a series of changes in the combined reaction and ultraviolet visibility spectrum of pyrodoline cobalt brackets and pyridine, and obtains the number of molecular numbers and balance constants.

Abstract: Parameter estimation theory is an important part of statistical decision -making theory. The work of this article is to promote the relevant results of the well -known statisticians Karlin [1] about the relevant results of the parameter estimation of the intercepted distribution family to α <0. And give an accurate MINIMAX estimate of parameter θ and θ2 in the Pareto distribution family in economics.
