Since 1992, on the basis of the mixed forest of Casuarina equisetifolia with Pinus elliottii , which was afforested in coastal sandy site in Chishan Forest Farm of Dongshan County, Fujian Province, the inter specific relation and structural proportion of species were regulated by thinning in row.
By analyzing the change of two species in height, diameter, and single plant volume after one year of the regulation. It is showed that the new model is 2 3 rows of Casuarina equisetifolia mixed with over 3 rows of Pinus elliottii , thus formes such disposition: wide row space of inter species, and close plant space in the same specie, which is benefit to the inter specific relation and the tree growth.
Based on loss mode of induction motor,specific relation between operation efficiency and working frequency of variable-frequency adjustable-speed induction motor is derived in this paper. In the meantime,relation of slip and frequency is found out and its characteristic is analyzed.
In specimens of normal gastric mucosa, intestinal metaplasia and dysplasia adjacent to carcinoma negative results were revealed, whereas overexpression of c-erbB-2 oncoprotein presented in 14/103 (13. 6%) of the gastric carcinomas with specific relation with nodal metastasis (P<0. 05).
Results showed that icariine could increase the level of GTH mRNA, but there was no specific relation between dose and effect; icariine dose of 60 μl/l gave the maximal level of GTH mRNA, which had significant difference with the dose of 30 μl/l and 100 μl/l.
However, both of the two methods have no specific relation with area control performance assessment criteria:CPS1 and CPS2. It is possible that even if all generating sets meet demand, but the area criteria is not satisfied.
Based on the theory and research in developed countries and combining with particular characteristics of Chinese stock market, this paper describes specific relation between Chinese monetary policy and stock market.
Comparisons of the relative contributions made by depressive and anxiety symptoms to the prediction of functioning yielded some evidence for a specific relation between depressive symptoms and impairment.
The response of a Van der Pol self-vibratory system to harmonic excitation is characterized by periodic and quasiperiodic vibrations in a specific relation.
Ascribing to a depressogenic attributional style did not mediate the relation between PTSD symptoms and disaster exposure, thus providing some support for an attributional-style-symptom-specific relation in the context of postdisaster adjustment.
Thoughts of loss and failure evidenced a specific relation with self-reported depressed mood while, to a lesser extent, cognitions of harm and danger demonstrated their strongest association with anxiety.
By studying the geologic structures and karstified rock formations in Guilin and analysing the development of karst depressions and caves there, we suggest that there exists an internal relationship between depression ;'nd cave in formation and development, which in turn reflects a specific relation in time and space.
Overexpression of c-erbB-2 proto-oncogene product (190KD) in 103 cases of gastric carcinomas and its relationship to prognosis as well as its potential in clinical application were investigated by means of ABC immunoperoxidase technic. In specimens of normal gastric mucosa, intestinal metaplasia and dysplasia adjacent to carcinoma negative results were revealed, whereas overexpression of c-erbB-2 oncoprotein presented in 14/103 (13. 6%) of the gastric carcinomas with specific relation with...
This paper provid a kind of control algorithm for plant with pure-time delay. This method is based on the thinking of setting up a model reference corresponding to the plant in fecdback channel of the system,but not requiring a specific relation between the model reference and plant model, and with a model reference output without pure-time delay which is cossected by the diversity of the plant output and delayed model reference output as the fecdback signal. This method is simple and do not req...
