In order to analyze the distribution of internal frictional force and determine the least layer number for expansion of coiler,the coiling process was studied with FEM.

Based on condition of strip coiling regulations,and the rules of nodes displacement change law of strip steel along coiler innermost layer during coiler expansion with different layers,the minimality layer was yield for safety coiling.

This paper studies the influence of the layer number of perceptron to its performance, with a aid of the linear model on the activation function of the neuron.

This paper takes a 300m high embankment dam as an example to analyze the influence of simulated layer number on the settlement of 300m high embankment dams by simulating the dam stress and deformation during construction.

There exists deep relationship between fabric layers and performance of warm-keeping, By warm-keeping instrument measurement of double-fold silk, Stape rayon, pure-cotton delaine and jaegers under different layers conditions, linear equation of the four fabrics are obtained.
