The checker instruction may travel down individual pipelines for each thread independently until it reaches a buffer at the end of each pipeline.
研究结果表明，打桩后桩体所受荷载向下传递，地基中的初始最大孔隙水压力出现在桩端以下土层。
It can be seen that the initial maximum pore water pressure takes place in the lower soil due to the load transformation from pile cap to soil.
变更从层级结构中向下传播：从获得的外部模型向企业传播，从企业向项目传播，从项目向执行者传播。
Changes propagate downward in the hierarchy: from acquired exemplar models to the enterprise, from the enterprise to projects, and from projects to practitioners.
在这种鱼道中出现的滚动流将产生波涌，并继续向下传播，而且它的周期性滚动可能会严重危害鱼道。
Tumbling flow is appeared in this fishway which produces wave surge and continues to flow downward and may causes serious damage due to its behaviour of periodic tumbling action.
研究表明：两个向上传播的重力波波包，通过非共振相互作用，也能激发出一个向下传播的重力波波包。
The results show that a downward propagating gravity wave packet can be excited by two up-going gravity wave packets owing to the nonresonant interaction.
突然我必须更努力的工作，确保所有经理都了解工作进度，因为信息不清晰在向下传递的过程中会被放大。
All of a sudden I had to work even harder to make sure all of the managers were up to speed with what was going on, because any confusion just gets magnified as it gets communicated down.
典型地，我们在闭包里储存由我们的语义动作产生的临时变量，以之作为在递归下降中向上或向下传递信息的方法。
Typically, we store temporary variables, generated by our semantic actions, in our closure variables, as a means to pass information up and down the recursive descent.
感觉刺激通过脊髓传到脑部，脑部的刺激通过脊髓向下传导到运动神经元，再通过周边神经到达身体的肌肉和腺体。
Sensory impulses reach the Brain via the spinal cord, and impulses from the Brain travel down the spinal cord to motor neurons, which reach the Body's muscles and glands via the peripheral nerves.
