A key point in Short Time Fourier Transform is the choice of window function. Although rectangle window is regarded as the first choice because it's featured by integral harmonic to filter signals and by DC component, decaying DC component and frequency shift of signals cause great error to rectangle window STFT. In addition, transient signals contain rich information of faults, but the fixed time window of STFT fail to collect these information.

According to this method,four different 11-step algorithms with four different window functions which are rectangular window,triangle window,hanning window,and blackman window are designed. Analysis and simulation show that hanning window and blackman window with small lobes are less sensitive to errors. Seven different algorithms with the same phase shifting interval π/2 are designed by hanning window function,whose phase shifting steps are separately 5,11,15,39,51,76 and 101 steps.

The differences between the edge of canopy gap and interior of forest and the differences between trunk surface temperature at the edge and surface temperature in the center of gap were also analyzed. The findings showed that there were high temperature regions on the east and north of middle vertical active surface of edge. So that the vertical active surface of edge is a new thermal active surface on the vicinage of canopy gap beyond soil surface on the interior of forest, soil surface on the gap, and forest canopy surface.

At the BCL of 500ms, 1000ms and 2000ms,the VWtimes increased markedly with the BCL prolonging, and the degree of increasing was even obviously when heart rate was slow (BCL=2000ms or 1000ms). The enlargement of VWs was a most important reason to increase the incidence of ventricular arrhythmias; 2）At the BCL of 500ms, 1000ms or 2000ms,the VWtimes of the premature stimulates S2 was at endomembrane were wider than at the outermembrane. We supposed that premature stimulates come from endomembrane was easier inducing VF compared with outermembrane;3The VWtime of unidirectional block was wider than reentry's, we can see that reporlarization dispersion changed dynamicly. 4The QRS polar of the premature stimulates was opposite the primary beats ,which suggesting that excitation of inducing premature beats was coming from epicardial. That is to say electrotonic potential take part in the creation of reentry;5With the ratio of the Tp-e/QT increasing the occurrence of VF was upgrading. So the ratio was an effective method to estimate the event of SCD.6 The VWtimes of S3 were broaden than S2's. But we can not study penetratingly, which is the contents of our future studies.

In this paper, based on a pill-box window model with a conical-shaped alumina ceramic and Ansoft HFSS software, the relation of VSWR with various electrical parameters in the window is simulated; the effects of variations of the output window structure on electrical field intensity, microwave power flow and quantity of heat are analyzed; the electrical characteristics of frequency bandwidth, power capability and heat dissipation for the pill-box window with conical-shaped or disk alumina ceramic are discussed, which shows that, with a rational structure of the window with conical-shaped alumina ceramic, the output capability of microwave peak and average power may greatly be increased, the secondary electron emission may effectively be suppressed, and heat dissipation may become more uniform and be easier for cooling.
