In model experiments, we find that the deviation of the first derivative calculated by Fourier transform is very large to comparing with the theoretical derivative, but the fitting effect of the derivative of anomalies calculated by cosine transform is very good. The calculation accuracy of data are all very high except that errors of several data on the boundary are large because of the residual Gibbus effect induced by finite truncation of gravity anomalies. Errors are -009%～5%.

The paper obtains some conclusions after many theories analysis and empirical tests: Firstly, Volume-price relativity is extensive: total volume or it's change, disassembled volume promoting price movement or it's change all has plus relativity to equilibria price. Secondly, there is unilateralisms Granger casuality in bullmarket, while there is bidirectional Granger casuality in bearmarket. There is not nonlinear Granger casuality in both markets. Third, Behavior finance has remarkable effects after contrasting to different investment conditions. Moreover, causality research by moving tendency can reflect the stable relation while usual causality research can't do. Fourth, it can be ture forecasing key period of tendency reversion by building volume-price elasticity coefficient containing composite information of volume-price and analysis methods of moving tendency.

针对这种情况，笔者认为，操作上可改进为：安装和调整量具时，先将干分尺调整到气缸套的公称尺寸，再将卡装好百分表和初步安装好插杆的量缸表直接卡入所测气缸套磨损最小处，调整量缸表插杆的伸出长度，使量缸表的百分表小表针有1.5-2.0格左右的预压量并将量缸表的插杆锁母锁紧，最后再将量缸表的测杆和插杆卡在千分尺的砧座和测杆之间并将百分表的大表盘调整到零。

Figure 2 shows the jigging concentrate relations between content and ore feeding volume, when the diaphragm jig and the sawtooth pulsation jig are provided with different ore volume. Figure 3 shows the jigging concentrate relations between the sulphur recovery rate and ore feeding volume. As the test result shows, when the tailing content reaches approximately 7%, the diaphragm jig has 1.00 t / h · m2 feeding volume, which is also the maximum sorting efficiency in the test. As such, the sawtooth pulsation jig could choose 1.2 t / h · m2 feeding volume. As the test contrast of two groups shows, the sawtooth pulsation jigging concentrate contains higher-grade sulphur than the diaphragm jigging concentrate does.
