It shows that under appropriate condition,the system is permanent,furthermore,sufficient conditions are derived that guarantee the existence of a unique positive periodic solution which is global asymptotic stability.
The reaction is carried on appropriate condition with respectively sulfuric acid and chlorosulfonic acid as sulfonating agent and it can get good water-soluble and high sulphur containing sulfated chitosan. The effects of dosage of sulfonating agent, reaction temperature and reaction time to sulfur content were discussed. The best technology was gained the molar ratio of sulfuric acid to chlorosulfonic acid was 1∶1,reaction temperature 5 ℃,reaction time 4 h.
The results show that appropriate condition is citric acid/ (Ce +Mo) molar ratio = 0.4 and pH = 1.0 for preparing Ce 2Mo 3O 12 ultrafine particle. The BET surface area of the sample treated in microwave oven is 35.8 m 2 / g, with the size of about 40 nm.
The results show that appropriate condition is citric acid/(Ce+Mo) molar ratio =0.4 and pH=1.0 for preparing Ce 2(MoO 4) 3 ultrafine particle. The BET surface area of the sample treated in microwave oven is 35.8 m 2/g, the size is about 40 nm.
The results showed that under the conditions of the temperature of 35℃,the TTC concentration of 0.1% and at the dyeing time of 3h the dyeing effect was the most appropriate. They could be the most appropriate condition to determine Kobresia capillifolia seed viability.
Through discussing the effect brough forth by overwhelming electric current while starting the electric motor,different starting ways of three phase electric motor were explanied,the merits and demerits and appropriate condition of different starting ways were compared.
②The optimum binding was obtained when the 3H ryanodine concentration was 1～30 nmol·L -1 and the membrane fraction concentration ranging from 0.4 to 1.0 g·L -1 . Conclusion 3H ryanodine can be used as a radioligand for analysing the RyR1 under appropriate condition.
This suggested that incubation at 6°C may not be an appropriate condition for studying enterovirus adsorption in explants.
From the results obtained, the appropriate condition is discussed for the operation of the melting furnace for ash from municipal solid waste incinerators.
Subjects in the sex-appropriate condition received information that their sex performed better on the experimental task; subjects in the sex-inappropriate condition received information that the opposite sex performed better.
The most appropriate condition for the detection of centered shock waves is the cavitation in cryogenic fluids, such as helium, for which γ ≈ 5/3.
Here Cd,p is independent of d or depends at most polynomially on d, and p can be arbitrarily close to the smoothness of functions belonging to a weighted Sobolev space with an appropriate condition on the weights.
