bottom level

This bridge is the core of communication of the controller system, it connects the bottom level backplane bus, backplane bus controller, and PC EPP parallel port.

该总线桥是某型协调控制器系统的通讯核心，实现了系统下层的背板总线、背板总线管理器与上位机EPP并口之间的协议转换以及通讯仲裁功能。

Research on bottom level architecture of PMS and its implementation

PMS底层结构的研究与实现

Due to the lack of deep exploring in bottom level of operating system, the behavior of the kernel-level malicious code cannot be monitored efficiently.

这样，由于没有对操作系统底层进行深入研究，检测不到操作系统底层的工作状态，无法对内核级恶意代码的行为进行有效监控。

Then, by the time we hit the bottom level, we bring out the big guns.

之后，等我们到达底层，再把大真理摆出来。

From the longitudinal aspect, it is three-level controlling architecture including production unit on top level, attemper level and production unit on bottom level.

以纵向的观点，是三层控制结构（顶层生产单元、调度级、底层生产单元）；

In real simulation game, bottom level survival behavior, mid-level strategy behavior and top-level game tactics and strategy, these three levels functions guarantee that the game can be performed continuously.

在实际比赛中，底层的幸存行为、中层的策略行为和高层的战术策略这三层提供的不同的功能使比赛能够不间断地进行。

If he is obviously nervous at the bottom level of the training scale, you are not going to have much luck with his collected trot.

如果他对低程度的训练明显紧张，你不可能要求他去更高的缩短快步。
