The possible influencing mechanism of weightlessness on cerebral circulation and its physiologial significance were summarized. It could be concluded that the changes of cerebral circulation were the results of self regulation of the brain to maintain its normal function, and it might play an important role in the genesis of postflight orthostatic intolerance.
So, enterprise is not only the biological organic body of survival development in environment and has self regulation and self development to eliminate contradiction and the ability of seeking development , is to be able to move land acclimatization since meeting system.
It is essential to enhance the whole nation's environment awareness, and by using ecosystem's self regulation mechanism and its principle of circulation and intergrowth to plan cities to enable them complex ecosystems of "society, economy and nature".
Methods According to the high and low of self regulation ,to select two groups randomly:60 patients with high self regulation group and 60 patients with low self regulation group. Each group is divided into four groups.
As to the scores of self regulation there is a significant difference in the low self regulation group 3 before and after interfering P<0.001,then three high self regulation groups are no significant(P>0.05).
Aganist the defects of Maslow's motivation theory, this paper elaborates systematically the encouraging, sustaining and strengthening functions of self consciousness on the individual achievement motive, reveals the mental patterns of self motivation and puts forward the countermeasures of perfecting self concept, strengthening the self regulation and performing the self motivation.
There was a positive correlation between RCR and RFER(r=0 92 P <0 01) and a negative correlation between RCR and RFIR(r=-0 86 P <0 01) Conclusion Red cell immune function of patients with liver disease was decreased and red cell self regulation system was disturbed.
Methods the patients in diabetic group include 45 cases with without intercurrent disease,53 cases with microangiopathy,44 cases cerebral infarct; 50 healthy volunteers as conctrol. The cerebral blood flow and Gosling pulsate index(PI) were measured by TCD apparatus and the patients were kept 60 months forward looking follow-up and the self regulation of cerebral artery were sequentially monitored.
The results indicate that the variations of morphology, geomorphy, hydrological regime and water pollutants have changed the perching conditions of aquatic living things of the estuary, decreased self regulation and restoration capability and homeostasis of ecosystem, influenced greatly on matter cycle, energy transfer, development, evolution and equilibrium in the ecosystem of the Pearl River estuary.
The technique of the self regulation electronic level has such advantages as tracing and adjusting electronic level of input signal automatically. Applied in the design of photoelectric sensor,this technique provides a satisfactory result of increasing receive capacity of the reflected signal.
