These results show that:(1) the results retrieved from the Abel integral and absolute TEC inversion are consistent on the whole at higher orbits altitude (~800 km), and in good agreement with those measured by ionosondes; the results retrieved from absolute TEC inversion are in better agreement with those obtained from ionosondes than that by the Abel integral inversion at lower orbits attitude (~500 km);(2) the maximal electron density N m from absolute TEC inversion is closer to N mF2 from ionosondes than that from Abel integral inversion, and the method of the former is more rigorous and effective than that of the latter;(3) absolute TEC is more sensitive to cycle slip than Abel integral, but for the two ways significant loss of inversion precision due to cycle slip always exists.

The non-reference-signal's adaptive digital filter algorithm of multi-sensor data fusion in the course of adaptive filter can be done without reference signals. It can adjust convergence constant automatically, it can also be recurred with real gradient value. Thus the field to apply the adaptive filter is widened, the convergence speed of the adaptive filter is sped up, the weighted disadjustmend is decreased, so that the last error of mean square approaches its minimum value more.

To analyze the response of pavement structure under moving loading, a quarter vehicle model with single freedom degree and unevenness model are established. The dynamic loads are calculated through combining different pavement conditions and speed. When the incentive frequency which is passed to vehicles by the road is close to its own vibration frequency, vehicles will produce the greatest dynamic load.

Under the assumption of a sech〓 input pulse, TOD is significant only for pulse widths less than 10 femtoseconds resulting in pulse broadening as well as distinct amplitude oscillations on the leading edge. TOD is positively correlated with its length. The calculations presented here allow for the determination of the maximum thickness of crystal that may be used in the autocorrelation system.

In addition, total wheel/rail contact calculation with divided rail outline method are raised. Under the condition of considering the displacement, bouncing, yaw, roll of wheelsets and displacement, bouncing, roll of rails, minimum gap between rail and wheel were calculated by the trochoid method and divided rail outline method, we can easily judge totally real contact states of the wheel/rail such as normal one-point contact, nonnormal one-point contact, two-point contact and wheel complete lift. Wheel/rail normal forces in the two contact point are respectively calculated by nonlinear Hertz contact theory, and then, result of simulation more close to reality on actual track.
