The system adopted active tracking,namely calculate the input angle of the tracking device in advance,the angle is correspondent to the sun position some moment.Photoelectric sensors react the sunlight that putting on different position of the platform, feedback electrical signal.Then single-chip applys the subprogram and sends out pulse to step motors according to the signals,can control the rotate angle and direction of the step motor. The mechanism has realized the automatic track to the sun, so that the trackers top flat board can be always vertical to the sunlight and arrive the furthest receiving energy.

The present research situation about AB process in and out of our country was analyzed in this paper. In addition to a concentrated study of the factors affecting sedimentation performance of A-step activated sludge, the rule of microbe multiplication, yield of activated sludge in A-step and treatment of low-concentration sewage were also involved in this paper. The main conclusions are as follows:(1) The study on factors affecting sedimentation performance of A-step activated sludge shown that the inflow SS distinctly improve sedimentation performance of activated sludge, the less influent SS makes the sludge bulking easy, and the pythogenous sewage evidently worsen sedimentation performance of activated sludge.

In this paper, some improvements have been made on the traditional gradient interpretation methods for the two-dimensional fault gravity anomalies:① The least squares fitting technique is adopted to figure out the dip angleαof the step;② The dip angle and the horizontal boundary of the step are directly used to calculate the burial depth of the step;③ the interpretation method for gravity two-dimensional gradient is extended to the interpretation of the complex fault model.
