Ar air regulators in multiple burner systems , hold constant air - fuel ratio and the mixture pressure with reducing burner port area of up to 90 % Ar空气调节阀用于多炉头系统，保持恒定的空气燃料比和混合气压力。
That is , the large bulk of the animals would have allowed them to maintain a fairly constant temperature even without a high metabolism 也就是说，这些庞然大物即使没有较高的代谢水平，也能保持一个相当恒定的温度。
For a given media , and at a constant total pressure and temperature , the partial pressure of oxygen is proportional to oxygen mole fraction 对一个给定的媒介，在恒定的总压和温度下，局部压力与氧的克分子数成比例。
The usual bottleneck in a conventional router is the relentless next - hop route table lookup for the constant stream of incoming packets 常规路由器中常见的瓶颈就是为不断送来的恒定的包流紧张地查找下一跳跃的路由表。
So far , most pump machines in ships are not taken action . when the level is high , pumps still work in high distance , which have the energy wasted 目前，国内绝大多数的泵船上的水泵机组未采取措施，电机的输出功率是恒定的。
I t adopts means of gravity tension which can make the belt at constant tensioning status , increase weighing precision 采用重力张紧，可使胶带保持恒定的张力，不需经常调整，有效地防止胶带打滑，保持信号速度的准确，提高计量精度。
A reliable device that will last for years . the tried - and - true firing chamber construction ensures high temperature precision with extremely consistent firing results 焙烧室设计经过实践的检验，保证了准确的温度和恒定的焙烧结果。
When a body is in homeostatic balance , various measures ? such as temperature , glucose level and so on ? are as close to “ ideal ” as possible 当身体处于恒定的平衡状态，包括体温、血中葡萄糖浓度在内的各种测量值，都会尽可能接近理想。
Moreover , they are completely reliable , since tidal power comes from the constant pull of the moon which tugs the tide up or down every 12 hours 此外，它们是完全可靠的，因为潮汐能来自月球恒定的引力，月球每12小时吸引潮水涨或落一次。
We ' ve seen already how maintaining a constant base current through an active transistor results in the regulation of collector current , according to the ratio 我们已经看到有源晶体管的恒定的基极电流是如何以系数控制集电极电流的。
