查询词典 impurity

Fluosilicic acid,which is the byproduct from phosphate fertilizer factory,reacts with ammonium hydrocarbonate to obtain ammonium fluosilicate,then reacts with ammonium carbonate to form settled SiO 2,after filtration,water washing,drying and calcining,high purity SiO 2 with less than 10×10 -6 metal impurity and less than 10×10 -9 uranium and thorium respectively is made.

由磷肥厂副产氟硅酸同碳铵反应得氟硅酸铵，再和碳铵反应生成SiO2 沉淀，经过滤、水洗、干燥、煅烧得高纯SiO2 ，其金属杂质总含量小于 10× 10 -6，含放射性元素铀和钍各小于 10× 10 -9，通过实验获得了适宜的工艺条件，反应温度 70℃～ 80℃，反应时间 1 5h～ 2 0h ，配料比n(NH4HCO3 )∶n(NH4 2 SiF6 =4 4。

C Thermally controllable light valves:As described above, the clearing temperature of PDCLCs can be increased by UV-curing because of the reduction of impurity concentration. Therefore, when the texture of a CLC cell in the UV-cured region are changed to focal conic one, the scattering of light from the sample is maximum. However, the clearing temperature of PDCLCs can be increased continually with continually irradiating with UV light onto the sample, but the scattering is unchanged.

当PDCLC照射紫外光的时间超过某一特定时间，则表面配向被聚合物薄膜破坏而达成散射态之穿透度最低状态，若持续照光聚合时，因仍然处於focal conic态，故穿透度不再改变，但单体聚合造成相变温度上升，直到单体全部聚合为止。

From gentlefolk down to the very poor, were divided into two groups without their choice, and in most cases, without their knowledge; one group being supplied with water containing the sewage of London, and, amongst it , whatever might have com from cholera patients, the other group having water quite free from such impurity.

显然，没有实验能设计来说明水的供应对霍乱传播进程的影响，这个实验的范围也是最大的。不少于三百万人，男女老少，各个阶层，从绅士到穷苦人，在他们不能选择，且大多数是不了解情况的条件下，被分成了两组；一组喝含有伦敦污水的水，其中有来自霍乱病人的排泄物，另一组被供应绝对不含此类不净物的水。

The results show that the quantity of duplex impurity in CSP thin slab is minute. The size of crystal grain of the steel strip side along the width direction during continuous casting and continuous rolling,cold rolling and annealing is finer than that of the steel strip center and the phenomenon is more obvious duing continuous casting and continuous rolling than during other processes.

结果表明：包钢CSP薄板坯中复合夹杂的数量极少，在CSP连铸连轧及后续的冷轧薄板生产过程中，铸坯、热轧板、冷硬板和退火薄板沿宽向边部的组织均较中部的组织细小，且铸坯和热轧状态下较为明显。

The numerical result shows that the contributions from the interface optical phonon mode with higher frequency and the LO-like half space mode to the binding energy and the Stark energy shift are important and obviously increase with increasing hydrostatic pressure, whereas the interface optical phonon mode with lower frequency and the TO-like half space mode are extremely small and are insensitive to the impurity position and hydrostatic pressure.

数值计算结果表明，高频支界面声子模和类LO半空间声子模对于结合能和斯塔克能移的影响是主要的，且随压力的增加而显著增大，而低频支界面声子模和类TO声子模的作用则很小，且对于杂质位置和流体静压力的变化不敏感。

Contain HA,pawpaw extract,whitening and moisturizing factor,quickly penetrate into deep skin,soften dear and hard hominess,dissolve dirt from hair follicle,instantly float and seperate impurity and harmful substances,remove dirt after massage,combine nourishing essence,moisture and regenerate epidermic cells,strengthen skin moisture and firmness,inhibit hominess sclerosis as the activating and whitening product with instant effect after use

本品含透明质酸，木瓜精华液，美白保湿因子等，能即时渗透肌肤深层，松软死皮及硬化的角质，溶解毛囊中的诸塞物，令各种杂质和有害物浮现被分离，经过轻柔按摩，即时被清除肌肤外，滋养成分更滋润新生的表皮细胞，增加肌肤的柔嫩度和弹性，减少角质硬化，使立即见效的醒肤美白品
