The invention discloses a multi-view video-oriented fast coding method and belongs to the technical field of H.264 / AVC (advanced video coding). The method is characterized by the following steps that: a left view and a right view are coded by a global search method to extract coding information at first; then the feature vector of a two-layer support vector machine (SVM) classifier is constructedfor frames in the right view except an anchor frame by using the two-layer SVM classifier according to the sum of squared difference (SSD) of the error amount predicted by a macroblock during coding,a coding residual state coded block pattern (CBP) and the utilization rate of the macroblock coding mode; the classifier performs corresponding coding according to a coding mode used for identifying the macroblock in a homogeneity and a flat area and the coding mode of the macroblock of a larger block coding mode; and the macroblock coding mode with a minimum rate-distortion cost is selected as an optimal macroblock coding mode. When the method is used, a rate-distortion optimization method adopted by an initial full mode search method is terminated in advance, by the optimized macroblock coding mode, the coding complexity is reduced and at least seventy percent of coding time is saved.

The invention discloses a method and system for adjusting error parameters in a power grid, comprising: calculating the percentage residual of the state variable according to the residual value of the state variable of the power grid; If the percentage residual is greater than the residual threshold, the state variable is used as a problem variable, and the relevant branch of the problem variable is used as a suspicious branch; the suspicious parameters of the suspicious branch are adjusted; Whether the change of the parameter will cause the function value of the state estimation objective function of the state variable to change, and if so, determine that the suspicious parameter is an error parameter; modify the error parameter to obtain the corrected value of the error parameter, and adjusting the suspicious parameter of the suspicious branch to the correction value. By implementing the method and system of the present invention, the accuracy of diagnosing faulty data is improved without reducing data redundancy.

The invention discloses an organic amendment capable of passivating Cu, Zn and Pb in soil of a vegetable field. The organic amendment is composed of the following components by mass percent: 10% to 50% of phosphate rock powder and 50% to 90% of wormcast. The organic amendment can be used for passivating heavy metals in contaminated soil, and especially used for passivating the Cu, the Zn and the Pb in the vegetable field soil which is moderately or slightly contaminated so as to decrease the content of the heavy metals in an acid extracting state, an oxidation state and other active states and increase the content of the heavy metals in an organic state, a residual state and other low active states, so that the content of the Cu, the Zn and the Pb in plants is obviously reduced, and a large quantity or an intermediate quantity of micronutrients required by the growth of the plants can be provided at the same time. Thus, the soil property is improved, the ecosystem health of the soil in the degraded vegetable field is restored, and the successive cropping obstacles of the soil are overcome. As a result, the yield and the quality of vegetables are improved.
