    • A method of measuring a target's position is provided. The method comprises: providing a marker for the target and a tracking assembly. The marker has a convex measuring surface, configured to be part or whole of a sphere, such that the center of the convex measuring surface substantially corresponds to the position of the target. The tracking assembly comprises a measuring piece, which has a tracking tool fixedly attached onto. One type of the measuring piece has a concave measuring surface substantially fit with the convex measuring surface of the marker; Another type of the measuring piece comprises a vision measuring system configured to be able to measure position of a center of the marker with respect to a designated coordinate system of the vision measuring system. The method to obtain the calibration relationship between the designated coordinate system of the vision measuring system and the tracking tool is described also. The method is more convenient and is able to improve the accuracy for measuring a target position.

    • Disclosed is a process for calcining a cement clinker with pre-heating and pre-decomposition at a high solid-to-gas ratio. During the firing of the cement clinker, the cement raw materials first exchange heat with heated flue gas in a pre-heater having a high solid-to-gas ratio, and then enter an outer circulation decomposition furnace having a high solid-to-gas ratio to complete the decomposition of carbonates in the cement raw material. The materials after decomposition enter a rotary kiln for calcination, and the sufficiently calcined materials enter a cooler for cooling so as to complete the calcination of cement clinker. The present invention uses a heat treatment apparatus with crossing material flows at a high solid-to-gas ratio to pre-heat the raw materials, and at the same time recycles the enthalpy in the waste flue gas efficiently; it employs the outer circulation decomposition furnace at a high solid-to-gas ratio to complete the decomposition of the pre-heated cement raw materials in a suspension form, reduces effectively the temperature of waste gas discharged by the system and the heat consumption per unit cement clinker, improves the thermal efficiency of the system, the apparent decomposition ratio of the materials entering the kiln, the production per unit volume of the decomposition furnace and of the rotary kiln, enhances the heat stability of the decomposition furnace, and simultaneously decreases the discharge of harmful gases, such as SO2, NOx, etc.

    • Adaptive filtering method to remove ground roll from seismic data. In an M channel adaptive filter, weights Wi are set using an adaptive algorithm based on seeking the minimum in the partial differential of cost function J. The cost function includes an expansion of the primary trace d into d = dg + ?d (where: dg is ground roll contribution and ?d = dsig + dran, where dsig is the reflected signal component and dran is a random noise component) and a corresponding expansion of the reference x into x = xg + ?x (where xg is ground roll contribution and ?x = xsig + xran; where xsig is a reflected signal component and xran is a random noise component). The delta components are included in the denominator of cost function J to provide an optimal solution of the filter coefficients biased by the reflection signal and random noise is removed.
