Although Inner Mongolia has a vast territory with a sparse population, the pressure of the social environment brought to it by the increasing population is still very great, because more than 80% of its territory is arid and half arid desert, its ecological environment very weak, the bearing capacity of its land small, and its regional economy not developed.
In the course of the society development,problems of the population scale,as well as the bearing capacity of the environment and economy become more and more urgent and severe,and arouse lots of society and security problems.
At present, our country is carrying the maximum populationwith the most rigorous resources conditions in history. The issueon the land resources population carrying capacity was paidclose attention to.
Reported QSRR models are critically reviewed, bearing in mind their statistical predictability physical meaning.
Synthesis and evaluation of five different N,N-disubstituted aminoethanol ester derivatives of indomethacin bearing structural resemblance to the aminoethanol ester class of anticholinergics are reported herein.
Influence of the Mechanical Seals on the Dynamic Performance of Rotor-Bearing Systems
In this paper, to consider the effects of mechanical seals, a lumped-mass model and the transfer matrix method are used to establish the equations for the dynamics performance of rotor-bearing system.
To check the response of the rotor-bearing system under unbalance motivation, the Gauss method is used to calculate the dynamic response of the constrained vibration.
