The combination of chitosan and titanium net could effectively inhibit proliferation of cicatricle surrounding dura meter.

结果：对照组瘢痕日趋明显；钛网组可减轻硬膜周围的瘢痕包裹，有效的隔绝周围瘢痕组织与硬脊膜；几丁糖组有明确的抗瘢痕粘连、抑制炎症反应的作用；几丁糖+钛网组能有效抑制硬膜周围瘢痕的增生。

The results show that the mineral admixtures can reduce C3A quantity in the cement material, and the pozzolanic reaction can consume lots of hydration product-Ca2, Which makes specimens close-grained, has obvious prevention function towards the sulfate corrosion. The anti-sulfate corrosion effects of various mineral admixtures from finer to poorer in turn are as follows: 30% fly ash, 30% fly ash + 30% slag, 60% slag, 30% steel slag + 30% slag, 30% steel slag, 30% slag, the blank type.

研究结果表明：加入矿物掺合料降低了试件的胶凝材料中的C3A含量，其火山灰反应消耗了大量的水化产物Ca2，且提高了试件的密实度，对硫酸盐侵蚀具有明显的预防缓解作用；各矿物掺合料的抗硫酸盐侵蚀效果由优到劣依次为：30%粉煤灰，30%粉煤灰＋30%矿粉，60%矿粉，30%钢渣＋30%矿粉，30%钢渣＞30%矿粉，空白样。
