The PP/PET in-situ fiberized composites with reinforcing effect were prepared by extrusion-drawing-injection molding.

The conditions for forming a solid core ply yarn are pointed out,and conclusions are drawn that the strengthening effect of twisting on the hollow core ply yarn is greater than that on the solid core ply yarn.

A statistic method is suggested for the strengthening effect of active mineral additives in cement and concrete.

In this paper,12 dominant diffuse-rooted species from riparian zones along the Jialing River were selected and their enhancement effects on soil anti-scouribility were determined.

The enhancement effect of the phase conjugation wave was studied,which was produced by a third order nonlinear optical medium(NLM) in a(AB)~N(D)~2(BA)~N Bragg microcavity made of one-dimensional photonic crystals.

The enhancement effect on cement material arises from chemical effect which is predominated by pozzolanic effect and physical effect which is predominated by filling effect.

Based on the model test and engineering practice, the basic rule of pile side resistance enhancement has been summarized.

We have experimentally studied the enhancement of channel plasmon polaritons (CPPs) propagating in silver groove surrounded by period corrugations.

It is deemed that there is an interaction between the pile shaft resistance and the pile base resistance, the enhancing response is ubiquitous for the pile shaft resistance around the pile end and intensifies with increase of soil strength underneath a pile.
