Models for estimating primary branch length and branch diameter within live crown were developed in Mongolian Scots Pine plantation in Maoershan experiment farm of northeast forestry university.

Branch growth for internode length(IL) and basal diameter(BD) was determine by vernier caliper,and their partial correlations with respect to the whorls were calculated.

Based on thoroughly analyzing the the diagnostic of mineral resources,the probability and basic approaches of realizing the sustainable exploitation of mineral resources has been studied.

The article summarizes the status of China' s petroleum consumption in 40 years and future growth trends, analyzes main risks facing China' s future petroleum safety supply and puts forward major principle and basic approach to accelerate the construction of China' s muitielement petroleum safety supply system.

There are four basic approaches for moral education in vocational schools, they are classroom teaching, living practice, personal relationship and moral education appraisal .

The thesis discusses how harmonious teacher-student relationship promotes teaching results,and puts forward some basic approaches to establish harmonious teacher-student relationships.

Radial Basis Function-weighted Partial Least Square Regression and Its Application to Develop Dry Point Soft Sensor;

A novel method integrating the radial basis function (RBF) with partial least squares regression (PLSR), which can describe complex nonlinear system, was established.

Based on researching into the classification mechanisms of feedforward single-layer radial basis function (RBF) and linear basis function (LBF) networks,the author presents the viewpoints that the RBF centers and widths should be determined through a self-learning procedure,that some new kernels naturally come into being according to which class the labeled patterns are misclassified to.
