(4)Formed the physical metric, monetary evaluating and the compensation standard into a the individual system by the organic mutually converting parameter, to discuss the compensation standard fort the forest ecological benefits, at last, put forward respectivelythe WTP adjustment parameter :the developmental stage coefficient is 0.3559, and the time adjustment parameter : the prepositional discount rate is 1.00%;
METHODS: Modified method of human peripheral chromosomal preparation and G-banding: The procedures were the same as routine methods, while partial influential factors were regulated, for example, the action time of colchicines was set at 2 hours before the ending; 1 mL of fixation fluid (the ratio of methanol and glacial acetic acid was 2:1) was added for pre-fixation, and samples were mixed and centrifuged at 1 500 r/minute for 10 minutes.
From the aspect of software reusing,being analyzing the development of Internet,the evolving of mode,the existing question and current situation,this paper applied the method to deal with the questions,in both sides of theory and practice,that is the Dynamic Web model (DWM).
To save energy and improve efficiency,the extract time was changed to two hours from three hours per time. The result showed that extract rate of total flavonoids was 5.225%,the average recovery was 101.45% and the relative standard deviation was 1.975% (n=5). It offers a scientific evidence for the further study of medicinal efficiency and comprehensive utilization of Perennial chamomile.
In this paper,space vector PWM (SVPWM) control method is introduced in the power factor correction (PFC) of arc welding inverter source. The input voltage vector of PWM rectifier is regulated to control the input current by changing manipulative time of eight basic vectors.
We did find, however, that within the constraints imposed by rise time regulation, compensatory adjustments to the force trajectories (Gordon and Ghez 1987b) were greatest during the period of specification.
Last, the tentative space-time regulation plan of the water resources is presented on the basis of the study of the environmental isotopes.
Various mechanisms are described for real-time regulation of the amount of contrast with which a pattern will be stored.
On 1 January 1996, the German Arbeitszeitgesetz (working-time regulation) came into effect for hospital physicians.
Many clusters corresponding to specific compound 3 tissue 3 time regulation patterns were visible.
