Oral twice this side, the litter can also increase Symplocos 3 grams,煮取decoction liquid immersion suffering from hand, about 20 minutes each time, there are emollients antipruritic role.

此方内服两次后，还可加枯矾3克，水煎煮取液浸泡患手，每次20分钟左右，有润肤止痒作用。

The adsorption behaviour of chemically different superplasticizers, such as melamine formaldehyde sulphite polycondensate,β-naphthalene sulfonate formaldehyde polycondensate and polycarboxylate, on early hydrating cement phases was studied. For this purpose, pure ettringite AF(subscript t, monosulfate AF(subscript m and syngenite were prepared. The adsorbed amount and zeta potential of early hydration products were measured.

制备了钙矾石AF(下标 t、单硫型硫铝酸钙AF(下标 m和钾长石类单矿物，并研究了三聚氰胺磺酸盐甲醛缩聚物、β-萘磺酸盐甲醛缩合物及聚发酸盐等几种化学成分不同的超塑化剂在其早期水化颗粒表面上的吸附行为。

X-ray diffraction, scanning electron microscope, energy dispersive spectrum and laser Raman spectrum analysis were used to identify thaumasite in paste sample stored in 10% of MgSO_(4) solution at different temperatures .

钙矾石型和石膏型等硫酸盐侵蚀破坏机理已得到广泛研究与认同，然而另一种硫酸盐破坏类型———碳硫硅钙石型却没有受到应有重视。

They are insoluble in water, ethanol, methanol, acetone, chloroform and benzene, but soluble in DMA, DMF and DMSO.

它们溶于N，N-二甲基甲酰胺、N，N-二甲基乙酰胺和二甲基亚矾等溶剂，但不溶于水、乙醇、甲醇、丙酮、氯仿和苯。

Linear change after baking of the gunning mix which takes clay and bauxite as aggregates and high alumina cement as binder can be obviously reduced by adding 30% alumina fine powder and 5% kyanite.

在以焦宝石、矾上熟料为基本骨料，以高铝水泥等为复合结合剂的喷补料中加入3％的Al2O3超细粉或5％的蓝晶石粉都有利于降低喷补层的烧后线变化。

Wood ash is one example. But chemical mordants such as alum are popular today. Alum is sold in many stores.

木灰就是个例子，但是化学上的腐蚀液，如现在受欢迎的矾，明矾在很多商店有售。

The experiment result shows that if Iron in the pickle of copper-smelting smoke ash is removed by Oxygen or oxidation combined with Hydrogen peroxide, Iron removing rate is 90%.

常用除铁方法主要有 [1 ，2 ] ：(1 )直接鼓风氧化生成针铁矿的形式除铁；(2 )用生成磷酸盐沉淀的方法除铁；(3 )用黄钾铁矾法除铁；(4)用过氧化氢氧化除铁；(5 )采用溶剂萃取法分离铁。

The existence of anisotropy in paramagnetic cubic crystal s has never been observed and it was only vaguely conjectured by Schlapp and Penney in 1932 for chrome alums.

立方顺磁晶体的各向异性从未有实验观察的报道，仅Schlapp和Penney(1932)在理论上对铬矾作过含混的臆测。

Vitriol mountain town alumstone exploits cost low , entire exploit be a strip mining, the ore may ascertain whose use , potasium sulphate , may produce alums , inferior may produce a swelling agent , early strong medium agent , accelerating agent first-class but giving birth to a child according to the grade.

矾山镇的明矾石开采成本低，整个开采是露天采矿，矿石可根据品位确定其用途，上等可生产硫酸钾、中等可生产明矾、下等可生产膨胀剂、早强剂、速凝剂。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
