That's a real critical issue--what is the range of temperature or climate conditions to which we can adapt, and when do we exceed those?
那是一个真正关键的问题——我们可以适应的温度或气候条件的范围是什么，我们什么时候会超过这些范围？
That's a real critical issue - what is the range of temperature or climate conditions to which we can adapt, and when do we exceed those?
这真是一个棘手的问题——我们能适应多大的温度和气候条件变化幅度，和什么时候我们会超越这个幅度。
Hardening. This is the process of heating to a temperature above the critical range, and cooling rapidly enough through the critical range to appreciably harden the steel.
淬火。这个工艺是把材料加热到临界温度范围之上，然后迅速冷却到临界温度范围以下，使钢材明显变硬。
If steel is heated slowly to a temperature just below the critical range and held there for a prolonged period of time, this structure will be obtained.
如果把钢缓慢加热到恰好低于临界温度并且保持较长一段时间，就能得到这种组织结构。
The resistance at reference temperature, its temperature coefficient, and the critical temperature of the material that the operating range of the sensor depended on have been obtained.
测得材料的基准温度电阻，电阻温度系数及能够确定传感器工作范围的临界温度。
Hardening is the process of heating a piece of steel to a temperature within or above its critical range and then cooling it rapidly.
淬火就是把钢件加热到或超过它的临界温度范围，然后使其快速冷却的过程。
The operation consists of reheating quench-hardened steel to some temperature below the critical range followed by any rate of cooling.
回火作业包括将淬硬钢重新加热到低于临界范围的某一温度然后以任意速率冷却。
The critical frequency decreases linearly as environment temperature rises in a special range.
临界频率在一定范围内随环境温度的增加呈线性下降趋势。
