In this paper,the trace of rocket following the energy central of dual point-source is derived,When the missile turn up to the critical of differentiate angle,the effect from critical of differentiate angle,distance between the dual point-source and SNR to attack trace are discussed.

The critical probability of overall collapse was presented,which simplifies the identification of the systematic collapse of zone groups to the comparison of the cell instability with.

292 893 3 by using a renormalization group approach, and correspondingly critical probability P bc of conduction of a crack is 0.

Fractal percolation is an important random fractal set, and the critical probability is very essential to the study of fractal percolation.

Reconstruction ionospheric critical frequency using Artificial Neural Network over limited region;

The critical frequency of ionosphere at linearity condition and the atmospheric refractive index formula are derived.

Nd:YAG CW laser heat-conduction welding——Ⅱ.calculation of critical power;

Then the Schrdinger-type nonlinear equation in strong nonlocality was given and from the equation the analytical expressions of the single soliton and the critical power .

In experiment,we observe the propagation of solitons in nematic liquid crystals,and determine the critical power of optical spatial solition in different beam width,for example,when the.
