The proper alkaline content was in favor of compressive strength. The chemically combined water of paste without activator decreases with the increase of fly ash content, the content of Ca2 decreases after 28d. The increase extent of chemically combined water of pastes with NaOH is higher than that of without activator, and the paste with Ca2 is the same. The XRD peak of Ca2 of paste without activator is high at early age, and the peak of mullite and quartz has less change along with age. When NaOH is added, the peak of quartz of fly ash has clear drop. The surfaces of fly ash activated has eroded trace at 7 d.

The results were as the follows: with the rising of Cr(superscript 6+) concentration, the Pro content in both root and epicotyls was first up and then down; the content of MDA and membrane permeability increased continuously; SOD activity deceased gradually and POD activity was first up and then down.

The simulation results of the cylinder-block model were given in the article, consistent with that of Middlemen"s. It was shown that the block part could improve the uniformity of the flow distribution. The analysis of the flow field of some materials with different power-law factor in the die designed by Mckelvey was close to that of Mckelvey"s. It was shown that the flow distribution was uniform in the die that can producesheets with 1200mm in width. During the analysis the flow channel was divided into several parts to get the details about the fluid flow in each area. A conclusion was drawn after analyzing the influence of the die pressure on the flow distribution, that the higher pressure is good for the output and bad for the uniformity of the distribution. Simulation of the die applying the cylindrical main runner showed the fact that when the cylinder replaced the cone the change of uniformity was trivial. The uniformity of the non-block flow channel was so poor that the block in the proper position of the die channel was necessary. The project of the die for the wider sheet was put forth, and the analysis of the fluid flow in the die was shown.
