The encoder first calculates the frame size for the preset's frame Duration and then compares the resulting sample count with the frame size Limit value.

编码器首先由预设值的帧持续时间计算出帧大小，然后拿结果的采样数与帧大小限定的值作比较。

The time base for this sequence is not known as it is taken from a televised slow motion recording however, the duration between each exhibited frame is constant.

其实，下面这些我们还不太熟悉的图象是扫描电视录象的慢镜头而成。不管怎样，所显示的每幅画面之间的持续时间却是固定的。

By solving recurrence equation of stochastic finite element, the duration curve of mean value and standard deviation of seismic response can be obtained for every floor of frame shear structure.

通过求解随机有限元的递推方程，得到框剪结构各层的地震动力响应均值和标准差历时曲线。

This makes it hard, for instance, to compare real-time video images (from a camera in the nose-cone of a missile, for example) with a set of several thousand targets (pictures of enemy aircraft, say), because all the targets have to be tested within a thirtieth of a second, the duration of a single frame of video.
