This limits the number of moving parts which need to be adjusted every time a photo is taken, and which cause a lag between pressing the shutter-release button and capturing the image.
这限制了在拍摄每一张照片时部件需要调整的配件的运动，并造成按下快门按钮和拍摄图像之间的延迟现象。

The results showed that the lagtime before drug release was lengthened with the increase of the viscosity grade of HPMC.
结果表明，HPMC粘度增加使药物释放滞后时间延长，但高粘度HPMC会导致药物释放无明显突跃点；
3
The factors which affect the lagtime and drug release behavior were investigated, such as the type and thickness of the inner and outer layers, the type and amount of the plasticizer, etc.
