The auidental and complicated branch pattern were treatmented by the foundmental principl of fractal geometry and the effect of the time and the branch number on the discharge rate (Se) were studied by using the discharge rate as an object function.

Keeping discharge rate (Se) as the target function, studies have been canied out on effects of the mobility rations of two kinds of fluids(petroleum solutions and aqueous ployacrylamide solutions) and sur face roughness(ε) of the model glass on the viscous fingering was not significant, when M≤1, Se were big,viscous fingering was significant when M> 1,Se were small, Increase in s caused the.

The excretion rate of ofloxacin in the urine of three healthy volunteers′ was assayed by PS-RTP.

CONCLUSIONS The excretion rate of fleroxacin in urine for two healthy volunteers after a single oral dose of 200mg fleroxacin ta.

The oxygen consumption rate, ammonia excretion rate and CO_2 emission rate of the juvenile summer flounder (Paralichthys dentatus) in fasting and resting states were determined, and the respiratory quotient, oxygen-nitrogen ratio, energy metabolism characteristics and chemical nature of energy source were also studied.

For evaluating the degree to which the supply air can remove indoor contaminants,gives an introduction to the concepts of the age of air,air exchange efficiency,ventilation efficiency,etc.
