The comparison and analysis of short-time heart rate variability in different diseases;

Objective To observe the influence of gender and age on the short-time Heart Rate Variability(HRV).

Simultaneous short-cut nitrification and denitrification;

Characterization of short-cut nitrification using immobilized ammonia-oxidizing bacteria;

A/O process short-cut nitrification with process control of DO and aeration based on DO and pH on-line sensors can be achieved,and gradually eliminated nitrite oxidising bacteria,and therefore achieved nitrogen removal via the nitrite pathway.

Study on factors affecting shortcut nitrification of mature landfill leachate;

Factors effecting shortcut nitrification for treatment of advanced stage landfill leachate;

Research on control strategy of internal-loop airlift reactor for shortcut nitrification;

Start-up and operation of partial nitrification in a sequencing batch reactor;

Effect of alkalinity on the [NH_4~+-N] ratio during partial nitrification in a sequencing batch reactor;

The biochemical reaction mechanism and kinetics of partial nitrification;

Preparation of biodiesel by short path distillation of rapeseed raw oil and alkaline catalyzing reaction;

A purification method —wiped film molecular distillation(short path distillation)is introduced in this paper;the optimum technical conditions for refining vitamin E by using this method was studied.

The purification method-wiped film short path distillation was introduced, and the optimal technical conditions for refining glutaraldehyde were studied.
