查询词典 shutter release

All enhancers did not significantly change the transcorneal lag time of ENX. The irritancy of poloxamer and Azone was observed.? The results of in vitro release studies showed that the ENX gel based 3% HPMC K4M and 3%HPMC F4M povided sustained release of the drug over an 8-h period in vitro.Diffusion area has significantly effect on drug release, and pH value of medium and rotation rate have effcet on drug release.However, the diffusion shield has no effect on drug release. The P_ value of the preparation based on 3% HPMC F4M was 1.34-fold of conventional eye drops of ENX.

体外溶出度试验结果表明，以3％的HPMC K4M和F4M为基质制备的ENX凝胶剂的体外释放行为符合眼用缓释制剂的要求；体外释放度影响因素试验结果表明，释放面积对释放度有显著性影响，pH值和转速略有影响，而扩散屏障没有影响；离体角膜透过实验结果表明，以F4M为基质制备的凝胶剂中ENX的表观渗透系数P_(app是对照组的1.34倍，说明F4M与眼角膜的相容性较好，是一种理想的眼用制剂增稠剂，可以在眼用制剂中广泛采用。

The IR analyses proved that the polymerization effects really occurred. The BET adsorption test indicated that the adsorption amount of MIPMs to LMD was as three times as that of non-imprinted microspheres. The controlled release test indicated that the release ratio of LMD on NIPMs was linearly increased with increasing time, which suggests that the release process is completely controlled by diffusion. Meanwhile, the release ratio of LMD on MIPMs was curvedly increased with increasing time, which indicates that the release process is controlled by both diffusion and the imprinting effect.

药物扩散实验表明， LMD在非印迹微球上的释药率几乎与时间呈直线关系，说明其释药过程完全受扩散控制；而LMD在MIPMs上的释药率则呈曲线上升趋势，说明其释药过程除了受扩散控制外，还受到药物模板分子与MIPMs之间的印迹效应的协同作用的控制，从而达到了缓释药物分子的目的。

No entire nitrendipine crystals were observed visually in SEM photos. The results of X-ray diffraction and differential scanning calorimetry analysis indicated that the crystalline form of nitrendipine was highly dispersed in microspheres, so as amorphous state. The drug release rate of microspheres could be controlled with adjusting the ratio of solid dispersion carriers and retarding agents formulated. The agitation speed and temperature of the preparation process have distinct effect on micromeritic properties of microspheres. The release profiles of the microspheres were mainly affected by the stirring rate of paddle, the concentration of SDS and pH of dissolution medium. Cooling speed and time, however, have no evident influence on the drug release rate of the microspheres. The dissolution data showed that the mechanism of drug release from microsphers was mainly diffusion-controlled. The incorporation efficiencies of 3 batches sample were exceed 96. 8％, which implied that the current method was suitable for design sustained-release dosage form for poorly water-soluble drug.

在扫描电子显微镜下观察，在微球内外未发现尼群地平的完整结晶，X-射线粉末衍射和差示扫描量热试验结果也显示，尼群地平已经被高度分散在微球中；微球的释药速度可通过调整处方中固体分散体载体和阻滞剂的比例控制；制备温度和搅拌速度对微球的质量影响较大；溶出仪的搅拌速度，释放介质的浓度和pH对微球的释放有较大的影响；制备过程中的冷却速度和冷却时间对微球的释放行为影响不很明显；方程拟合的结果表明缓释微球的释药行为符合扩散机制；测定三批微球样品的包封率均在96.8％以上，表明该法适合于制备难溶性药物的缓释微球。

The vitro release result which used theophylline as model drug showed, the release behavior can divide to sharp release 、 relaxedly release and equilibrium release periods.

以茶碱为模型药物，模拟体外释放的结果表明，共聚物胶束对茶碱的体外释药可分为突释、缓慢释放、平衡释放三个阶段。

为评测卷帘式航摄快门曝光时间的均匀性，根据有效曝光时间的分析计算，提出了一种可变缝宽式快门有效曝光时间均匀性的测试方法。

Although factors that affect the quality of an image captured at high speed include scene luminance, aperture size (f-number, f/#), shutter speed, and field of view, a simple calculation can determine the approximate shutter speed needed for such an application.

尽管影响高速捕捉图像质量的因素包括场景的亮度、镜头大小、快门速度和视野，不过对于这样的应用场合可以很简单就计算出大致所需的快门速度。

If your shutter speed is fast (eg 1/4000th of a second) it's not going to see much movement (unless the the subject is moving mighty fast) while if you select a longer shutter speed (eg 5 seconds) you don't need your subject to move very much at all before you start to see blur.

如果快门速度较快（以1/4000s为例），看不到较多的动态，如果你选择了较慢的快门（5s），要让目标物体模糊，你不需要运动物体移动很快。

At that time, the High Court of England and Wales Court of Queen's Bench president of William Murray, Lord Mansfield in June 22, 1772 ruling:"No matter then there is the inconvenience, but there must be a decision, I can not say that this case under the law in England are permitted or authorized; are so black should be released."
