The anticline structure model of overlaying variable velocity layer was established and the physical modeling testing and migration processing analysis carried out.

建立了上覆变速层的背斜构造模型，并对物理模拟实验结果和偏移处理效果进行了分析。

Incidentally we do use sudden shifts for wide lateral skips under special circumstances but we don't use them for ordinary scale and arpeggio passages.

顺便说一下，只有在大跨度的横向变换弹奏的特殊情况下，我们才使用"突然变速法"，但我们决不在一般的音阶和琶音中使用。

C. Using a 2mm Allen wrench, turn the black adjustment set screw clockwise to make the two-speed shift later; turn it counterclockwise

c。 以2mm的L形内六角扳手转动黑色调整螺丝：顺时钟方向转动让2段变速的换档时间晚些；逆时钟方向转动则会提早2段变速的换

He changed speeds and mixed in an effective change-up he threw more often than any time in his burgeoning career.

他试著改变著球速，并且搭配上一个够水准的变速球，而这场比赛也是他快速进展的职业生涯中首度投出如此多的变速球。

I'd like to see him use it more often with two strikes to right-handed batters; this change-up projects to be a much better pitch to right handers than his slider does.

我希望能多看到他在面对右打者且两好球的时候投变速球；这颗变速球对右打者时显然比他的滑球有效。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.
