In common glass fiber reinforced polyolefine pipe, when the volume faraction is less than the critical value, the glass fiber can not act as reinforcement, on the contray, it would reduce the whole intensity of the compound material. However, when extruded in combined stress field, the extend intensity of the compound system increases when the volume fraction of glass fibers is less than the critical value. When the glass fiber volume fraction is higher than the critical value, the required glass fiber volume fraction of compound fibers extruded in the combined stress field is less than theory value.

The critical rationalism proofs that the demarcation standard between science and non-science is falsifiability; but Feyerabend insists that the demarcation standard between science and non-science should be cleared up. The core of critical rationalism is perjury methodology. He considers the scientific method is not induction but deduce inspection. Feyerabend retorts critical rationalism School still can't be escaped from angle of view of the logical empiricism.

Besides, the reduction of the dispersion part of potential leads to a lower critical temperature and higher in-plane part of molecular dipole moment; however, because the reduced critical temperature is relatively small compared with that of a 3D system, disappearance of the critical point has not been observed in the quasi-2D SM system within practical scope of the simulation.

In this paper, Newton iteration formula for computing normal depth and critical depth was put forward by mathematical transformation of uniform flow equation and critical flow equation of circular section tunnel. Then, the relationship between the corresponding central angle and the introduced parameters was analyzed. An approximate formula for angle was obtained according to optimal uniform approximation principle. Using this approximate formula as initial value of iteration formula, a direct formula for calculating normal depth and critical depth of circular section tunnel was established after its first iterative.
