According to petrographic facies test, gravel sample mainly consists of quartz, albite, dolomite, and minor biotite; and sand sample is mainly made up of quartz and albite. As an important ASR active mineral, chalcedonite exists in fractures of dolomite and in matrix of cherty limestone. In rapid mortar bar test, expansion of sand, small gravel and middle gravel at 14 day are less than 0.1%, but keep increasing in long term.

岩相法检测显示卵石样品主要由石英、钠长石及白云石和少量云母类矿物组成，砂样品主要由石英、钠长石等矿物组成，重要的碱活性物质玉髓主要出现在白云岩裂隙和硅质灰岩的基质中；&砂浆棒快速法&检测结果显示砂、小石、中石样品14天的膨胀率均不超过0.1％，为非碱－硅酸反应活性骨料，但卵石样品仍具有一定的碱活性，且后期膨胀率一直持续增长。

For usual acid"s leaching out efficiency is low for Gallium in fly ash, we did some analysis on fly ash which drew out or not through X-ray, electron probe, and scan electron microscopy chlorhydric acid .And those analysis gave us rational explain that the low leaching out efficiency for Gallium from fly ash with chlorhydric acid"s draw out juice.

针对常规酸对粉煤灰中镓浸出率偏低这一现象，我们通过X-射线、电子探针和扫描电镜对盐酸浸出反应前后粉煤灰的分析，对盐酸浸出粉煤灰中镓的浸出率低作出了合理的解释。

Using the 1:1 chlorhydric acid and fly ash that has been incinerated react 8h by whisking sometimes . The cioncentraction of the draw out juice of Gallium is 10.9ug/g, The leaching out efficiency is percent of 35.2. The Galliums content and its leaching out efficiency is changed a little in the fly ash pass incinerating.

用1：1的盐酸在60℃下与焚烧后的粉煤灰间歇搅拌反应8h，浸出粉煤灰中镓浸出液中浓度为10.9μg/g，浸出率为35.2％；焚烧后不同粒级粉煤灰中镓的含量和浸出率没有明显的不同。

Thiazolidiane-4-carboxylic acid was prepared and used as the aid catalyst that has strengthened the catalytic effect of chloroplatinic acid, greatly improved the yield of the hydrosilylation of methyldichlorosilane with allychloride, and made the yield get to 64.9%.

通过比较，选用自制的含硫化合物4-羧基-1，3-噻唑烷作助催化剂，大大增强了氯铂酸的催化活性，使甲基二氯硅烷与氯丙烯的加成反应以较高产率得到γ-氯丙基甲基二氯硅烷，产率可达64.9%。

The relevant experiment was also conducted. Results In treatment group, the general symptom eliminating time was 11.2±4.7 dags; in intensive phase,the adverse reaction occured in 714 cases in all;sputurn negative conversion rate was 93.33%;drug resistance rate was 5%;X-ray obviously absorbing rate was 68.3%;cavity closing rate was 77.8%;alter treatment completed,cure rate was 96.67%.

结果 治疗组结核病人的一般症状消失时间为11.2±4.7天；在强化期内，化疗药物毒副反应发生率为14人次；痰菌阴转率为93.33％；耐药菌株发生率为5％；病变X线明显吸收率为68.30％；空洞闭合率为77.80％；全部疗程结束后，其综合疗效达96.7％。

The ratio of PMNs activity was distinguishingly higher in patients with positive blood culture,and also increased in patients with positive results of midstream urine culture and sputum culture.

血培养阳性的全身感染PMNs活化率最高，中段尿培养及痰培养阳性者PMNs活化率与正常对照相比也增高，但低于血培养阳性者。4 2例感染组患儿PMNs活化增加占78 。6 %，C反应蛋白增高仅占31%。

The results showed that the particle-electrodes had good electrocatalytic activity and stability for the degradation of phenol.

结果表明，该粒子电极对目标污染物苯酚显示了良好的电催化活性和稳定性，在相同反应条件下，不加粒子电极的二维电解时苯酚的降解率为55.6%，而三维电催化氧化过程中降解率为90.8%，大大提高了苯酚去除效果。
