At constant viscosity, by increasing the liquid flow rate, the liquid film's velocity is increased; at the same experiment condition, the frequency of the liquid film is same at the same radial direction; the air current has minimum effect on liquid film bottom flow velocity, while it has an obvious effect on liquid film surface flow velocity. The longer the distance between liquid film and the inlet, the lower the pulsatory frequency and longer the wavelength.

Chapter 2 discusses the function of optimum array based on the minimum meansquared error principle in CDMA system, the method of produce the reference signal, and proved whether the reference signal is the correspond PN code sequence or respread signal, the result of the array's weight converge can converge the same optimum weight under the condition that the PN sequence in a bit of data is long enough. In this chapter, we finally get the beam pattern and the correlate bit error rate after converge when several CDMA signal arrives in different direction.

Steps of the invention are that an agitator in a main reaction region is started while water enters to implement the nitrification process under the hypoxic condition. When a maximum value appears on a pH value curve and an inflection point appears on an ORP curve, the stirring is stopped. When the last stirring stage is stopped, oxygen is added in the mixture for the degradation of organic compounds and the nitrification of nitrogen compounds. When a minimum value appears on the pH value curve, the aeration is stopped. The steps are repeated till the water inletting stage is finished. And an aerobic aeration stage is taken as an ending stage of a reaction period.
