RESULTS: The nNOS average grey degree of hippocampal CA3 pyramidal neurons was significantly lower in stress group (155 42±3 77)than that in control group(164 54±4 62)and in stress plus phenytoin group(164 27±2 55)( P <0 01);
RESULTS:The iNOS average grey degree in the prefrontal cortex of stress DPH g roup(161.76±3.01)was significantly higher than that of stress group(156.99± 2.18),and had no significant difference as compared with control group(158.33 ±5.95).
the expression of eNOS,nNOS and Bcl-2 average grey degree in liver tissue of rats from overload training group increases remarkably(p<0.05),but the expression of iNOS and Bax average grey degree reduces remarkably(P<0.05).
The principle and its analysis steps of the method were introduced, the grey nature of r was pointed out, the cause of producing r's grey nature was analysed, the composition of r was resolved, the grey fraction was segregated from r, and the conception of grey degree of r in the sense of identical-discrepant-contrary analysis was advanced which revealed the internal connection among mathematical statistics, grey system and set pair analysis.
The result show that while studying the correlation relationship among facters, the problem of grey degree of r should be considered besides the significance test of r, that is to say, only in the conditions of r reaching the significance level and satisfying lower grey degree (temporarily established it as below 0.3) , the result obtained is reliable.
In this paper,According to the GPS observation data during the period from 1990 to 1993 and the grey system theory,the grey prediction model GM(1.1) of landslide and rockfall is established,and the grey degree of association is analysed.
(2) it is found that the influence of national economic character factors is larger than that of industrial economic character factors by grey degree ranking of correlation, which indicates China iron and steel industry has not achieved economy of scales, production differentiation and specialization;
This paper presents an internal-combustion engine fault diagnosis system by combining the theory of grey system with the traditional vibration diagnosis technology. It makes a diagnosis and inspection of the equipment operation condition,and analyzes and clusters samples by using the grey degree association.
In this study, a method is proposed, using GMS-3 satellite digital data every three hours, for analyzing the relation between cloud grey degree and rainfall. Several parameters are thusobtained, from which rainfall intensity and locality in the "A, B" areas have been satisfactorily estimated in three hours.
This paper first provides the axiomatic definition for the grey degree of the grey set, and then gives various kinds of formulas for calculating grey degrees. Finally, this paper demonstrates some operational properties of the grey degree,
