层流式隧道；空载不加热；风机空气洁净度；玻璃瓶清洁度；静态验证

Methods The air flow speed,pressure gradient,fallout bacteria and suspended granules were all examined at each working stage while the laminar flow tunnel was off-loaded,non-heated or only the fan was turned on.

方法在层流式隧道空载、不加热、只开风机条件下检测各工段的风速、压差、沉降菌、悬浮粒子及选用抗生素玻璃瓶的初始微生物、清洁度、灭菌效果等。

In addition, in the pressure side, the effect of Coriolis force makes the low-speed streaks slenderer and the space between streaks smaller, and in the suction side, streaks almost disappear and the flow has the tendency to become laminar.

由於科氏力的作用，压力面附近的条带间距减小，条带变细、变短，而吸力面流动脉动衰减，有层流化的趋势。

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.

因此，本文以难溶性的格列齐特为模型药物，在传统型推拉式渗透泵的基础上，设计并制备了双面打孔型推拉式渗透泵；通过单因素研究从含药层处方、助推层处方、衣膜处方、释药孔性质、压片工艺以及体外释药条件六个方面，对影响双面打孔格列齐特推拉式渗透泵片释药行为的因素进行了详细的考察，同时，应用相似因子法对以上各种因素下双面打孔型推拉式渗透泵和传统型推拉式渗透泵释药特点的异同进行了系统的研究；在此基础上，通过对双面打孔型推拉式渗透泵含药层和助推层黏度的测定，结合流体力学中的Poiseuille层流定律方程，对双面打孔格列齐特推拉式渗透泵片的释药机理进行了较为深入的探讨。

As the distance away from the entrance increases, the magnitude of pressure undershoots increases at first, then, decreases linearly. But the period of stratified flow increased linearly.

随着测压点离管道入口距离的增大，压力&过降&值先是增加然后线性降低，而短暂分层流周期的大小则线性增大。
