查询词典 layer

The structure changing feature of refractory in corrosion process is that there are decarburizing layer and metamorphorsis layer. In order to increase the resistance to melt for refractory containing graphite carbon, the forming rate of decarburizing layer and metamorphorsis layer must be controlled efficiently.

The foundation of arch dam usually is layer rock base, and the depths of the layer are small, it is common that several layer rock base contact with one layer element grid. According to the geometry relation and the property of shape function, a new element kind that includes 24 nodes has been proposed to dissect the dam and foundation effectively, whose shape function are independent. In fact the element can be looked as a hexahedron divided into five small hexahedrons. It can be simulate all kind of the condition of the base and the dam.

拱坝的地基一般是层状岩石地基，有的层厚度很小，这样就有多个岩层和坝体某层单元接触，本文根据岩基与坝体接触的几何关系，利用形函数的性质，提出24节点六面体层单元，这种单元实际上是将一个厚的六面体单元分成5个更薄的六面体单元而形成的，其形函数采用可以拆分的形式表达，因此可以方便地解决坝体单元的一、二、三、四个面与错动带接触的情况，可以模拟一、二、三、四个棱边与错动带接触的情况，还可以退化为12节点的四边形面单元，以及五面体层单元。

For this reason, a novel PPOP was designed and prepared using two side drilling technology and water-insoluble drug gliclazide was employed as model drug. Influencing factors from six aspects were studied which was drug layer formulation, push layer formulation, coating formulation, orifice properties, tableting art and dissolution conditions, respectively, and the difference between the dissolution profiles of novel PPOP and conventional PPOP was also evaluated by similarity factor (f_2). Through determination of the viscosity of drug layer and push layer of the novel PPOP, the mechanism of drug release from novel PPOP was discussed by the help of Poiseuilles law of laminar flow.
