The emulsion quartz stone material protective agent's solute has certain active multi-compositions and so on of functionality siloxanes and fluorine silicon hydride, this kind groups with the active ingredient carry alcoholysis reaction the ion condition water on quartz stone material surface, thus causes the siloxanes and the fluorine siloxanes has chemistry keying connection with the quartz stone surface, from outside to inside of the quartz stone surface and stone inside pore surface forms a kind of complex network structure, this kind of network structure is extremely dense, it may filter polar and carbon dioxide, slows down the speed that water molecules go in and out the quartz stone pore, so the quartz stone will not be soaked by the water molecules, meanwhile to be a barrier to stop alkaline compounds and salt to infiltrate from an interface to another, also can have the very good physical enhancement effect.

乳液型石材防护剂的溶质是具有一定活性的多官能度的硅氧烷和氟硅烷等组成，这种带有活性成份的基团与石材表层离子态水进行醇解反应，从而使硅氧烷和氟硅氧烷与石材表面进行化学键连接，由外向内在石材表面和石材内部毛的表层形成一种结构复杂的网状结构，此种网状结构极其密实，它可将极性水分子和二氧化碳进行过滤，减缓水分子进出石材毛孔的速度，不会被水分子浸湿，同时还有阻隔石材不同界面的碱性化合物和盐份向另外一个界面渗透，同时还能起到很好的物理增强效果。

The metal sample is dissolved with HCl H 2O 2, and the dissolved nickel is separated from other activation products by anion exchange. Nickel is then complexed with pealetyldioxime in the alkaline solution, extracted with toluene, and finally determined by liquid scintillation counter.

先将样品用HCl H2 O2 溶液溶解、再经阴离子交换、氢氧化物沉淀分离后，在碱性溶液中用丁二酮肟配合镍、甲苯萃取、稀HCl反萃后再用液体闪烁计数器测定反萃液中6 3Ni放射性活度、原子吸收分光光度计测定金属中稳定镍。

It was that using the refined alkaline barium chloride solution which was produced by the circular ammonium chloride solution leaching low-grade barium mineral as interim material,and adopting EDTA and the condensate sal volatile by using the liquid co-precipitation method to prepare the high purity spherical barium crbonate.

以氯化铵循环液浸取低品位钡矿制备的碱性氯化钡溶液为中间原料，添加EDTA与冷凝碳酸铵的溶液，通过液相共沉淀法制得高纯球状碳酸钡。

The separation purities by new method were determined and compared with those of some traditional methods by SDS-PAGE gradient electrophoresis.

其次，采用中性蛋白酶、碱性蛋白酶等几种常用的蛋白酶对分离的7S和11S球蛋白进行酶解比较实验，发现在相同条件下，7S比11S酶解后的酸溶多肽得率高，7S比11S相对更容易被酶解；通过扫描电镜和SDS-PAGE电泳分析7S和11S的酶解产物，表明7S和11S分子酶解前后的变化明显，但两种大豆蛋白经酶解作用后，均有相当部分未被酶解的蛋白分子残留在酶解残渣中，而酶解离心后的上清液中则已基本不存在原来的蛋白质大分子。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
