蒙脱石是~种层状结构的铝硅酸盐矿物,理论分子式为(OH)_4Si_(?)Al_4O_(20),单位晶胞系由二层Si-O 四面体夹一层Al-(O,OH)八面体所组成,晶胞呈平行选置。蒙脱石具有很高的吸水性,吸水后体积可膨胀数倍至三十余倍。在水介质中能分散成悬浮液。这种悬浮液有一定的粘滞性、触变性和润滑性。利用蒙脱石的上述特性,我们研制成功用于超声诊断的超声传导胶。原料取自国产蒙脱 Montmorillonite is a kind of layered aluminosilicate mineral with the theoretical formula of (OH) _4Si_ (?) Al_4O_ (20). The unit cell consists of two layers of Si- , OH) octahedron composed of unit cells were paralleled. Montmorillonite has a high water absorption, after the volume of water can be inflated several times to thirty times. In aqueous media can be dispersed into a suspension. This suspension has a certain viscosity, thixotropy and lubricity. The use of the above characteristics of montmorillonite, we developed the successful use of ultrasound-guided ultrasonic plastic. Raw materials taken from Montreux

图书发行业在我国已有很长的历史。西汉末的扬雄(前53-18)曾在《法言》中说到:“好学而不要诸仲尼,书肆也。”可见当时已有了“书肆”这种专门售书的场所。六朝人所著的《三辅
