We chosen three time 1 month、3 month、6month after the treatment and compare the symptoms、electrocardiogram changes、glonoin reducing rate、life quality、hospitalized times for CHD、adverse reactions to drug of the two groups patients.

分别选取治疗后1个月、3个月、6个月三个时点，对两组患者症状、心电图变化、硝酸甘油停减率、生存质量变化情况、因冠心病再入院次数、药物不良反应等进行观察比较。

The image showed that the ratio of raw material of RPC and particle distribution accorded with maximum packing density theory, and the porosity of accumulation was the least. The DSC showed the reaction rate of RPC was very fast and main hydration process focused in shorter time; SEM and X-ray showed that structure of the harden body of RPC was much denser, which mainly composed of some abnormal flat grains that got maximum packing density, and hydration products were mostly composed of Ⅲ type C-SH gel and a small amount of Ca2 and no AFt crystal.

由图象分析可知，即C原材料的比例及颗粒度符合密实堆积原理，堆积物的孔隙率达到最小；差示扫描量热分析表明，RPC的水化反应速度很快，主要的水化过程集中在较短时间内；扫描电镜及X衍射试验表明，RPC硬化体的结构非常致密，主要由一些不规则状的扁平粒子紧密堆积在一起，水化产物主要是Ⅲ型C-S-H， Ca2晶体的量稀少且没有钙矶石。

The experiment gone in a hermetical batch reactor,in this paper cellulose was hydrolyzed with extremely low acid as the catalyst in the high-temperature and high-pressure condition. Factors influencing the sugar yield and cellulose conversion ratio by hydrolysis including reaction time and the concentraction of the acid were studied systematically.
