Bioreactor can improve nutrition transmittability, provide hydrodynamic environment, induce shear stress, and promote production of cartilage specific matrix protein.
Field experiment was conducted to investigate the effects of treflan injection on dripper clogging and root distribution,yield and quality of winter wheat.
The experimental results indicated that the frost layer grew very slowly with the effect of ultrasound,and the frost layer composed by “frost line” was more inerratic.
In this paper,the relation of heterotrophic bacteria to nitrogen and phosphorus in marine environment is studied by adding nitrogen and phosphorus to the seawater in mesocosm.
Then ultrasonic wave and solvent were exerted into the crystallizable solution to change its natures,adjust the formation of crystal water and affect the change of crystal configuration.
