1%的产品为研究对象，通过磁选、酸洗、过筛、还原漂白除铁等方式提高产品的烧成白度，并对不同的试验研究和反应机理进行探讨。

Experiments show that the formation of tertiary dendrite depends strongly on the alloy type and alloy content. It is hard to form tertiary dendrite for hypoeutectic but easy for hypereutectic.

试验表明，三次枝晶的形成强烈依赖合金类型和合金成分，亚共晶的Pb-Sn合金很难形成三次枝晶，而过共晶的Pb-Sn合金则易于形成三次枝晶。

For example, when the added concentration was 0.04%, after heating for 8 days at (55±1)℃, the POV of teaseed oil added BHA, D-isoascorbic acid, ascorbyl laurate and D-isoascorbyl laurate were 66.6, 53.8, 35.0 and 20.6 meq/kg, respectively.

当添加量为油重的0.04%、在(55±1)℃下进行强氧化试验8d后，添加BHA、异V、V月桂酸酯和异V月桂酸酯的茶籽油的过氧化值分别为66.6、53.8、35.0和20.6 meq/kg。

The experimental result shows that after reclaiming the tailings with garbage fertilizer, Leucaena leucocephala Dewit. can grow well on the tin-zinc tailings pond while it is restricted in the tailings ponds without any reclamation; the contents of As, Pb and Zn in Leucaena leucocephala Dewit. are not high, only a little above those in normal plants.

试验结果表明：在用垃圾肥对尾砂进行改良之后，银合欢能在锡锌尾砂库上较好地生长，而在未经过任何改良的纯尾砂库上则明显受到抑制；银合欢不同组织中的As、Pb、Zn含量均不高，仅略高於一般植物的背景值。

The investigators examined fetal outcome data from 972 pregnancies collected from 1997 to 2002 in a nested case-control study. The participants were nulliparous and had no known medical complications. Pregnancies were grouped in eight categories based on the presence or absence of combinations of hypertension, hyperuricemia, and proteinuria.

研究者检验自1997年至2002年一项病例控制试验中972次怀孕的妊娠结果，受试者皆为第一次怀孕，而且没有已知的其他疾病；根据高血压、尿酸过高、与蛋白尿的有无，将怀孕分为8个项目。

Three different powers of high-intensity ultrasound are introduced into molten Sn-Sb peritectic alloy to study the refining effectiveness.

Sb过包晶合金进行了试验研究，考察了不同凝固速度条件下获得的凝固组织、相的形貌及初生相体积分数的变化。

In this before-and-after trial in a community private practice setting with extensive experience in pilonidal disease, 31 patients with severe refractory pilonidal disease had undergone a total of 141 operations, with wounds still open for a combined total of 252 years.

这个在民间社区所进行有关潜毛症的临床试验中，参与的31位全是顽固性潜毛症患者，所有患者总共做过141次手术，伤口保持开放的时间总共也有252年，其中27人平均追踪时间长达20个月。

The TiB2 cathode coating was tested in existing 190kA prebake cells.

3在现行190kA预焙铝电解槽上进行了TiB_2涂层阴极的工业生产试验，考核在用焦粒焙烧所产生的热量制备TiB_2涂层阴极的过

Methods A random and open clinical trial was performed in children at more than 18 months of age, who were uninoculated with HA vaccine, and adults at 18~35 years of age in Yancheng City, Jiangsu Province, China.

采用随机、开放式试验设计，选择出生后未接种过甲肝疫苗的18月龄以上的儿童和18~35周岁的成人，接种冻干甲肝减毒活疫苗1针。

To analysis crystallization kinetic equations, it was showed eligible stirring rate dependency and the high order dependence on supersaturating, which suggested that crystal growth of 6APA was surface integration controlled.

浓度推动力对于成核速率大于搅拌速率以及悬浮密度的影响，表明6APA成核过程同时包括了初级非均相成核以及二次成核；搅拌速率对6APA成长速率的极小影响以及过饱和度的较大影响，说明在试验条件下6APA晶体生长为表面反应控制。
