数量级

Because the THz is between the millimeter wave and the infrared, it is difficult to produce the THz radiation resonance. But the application such as the radars and far distance detecting need great power THz resource. The gyrotron is the only device who can produce great power THz wave.

由于THz波段处于毫米波与红外线之间，THz辐射的产生困难很大，目前THz源的输出功率大多在毫瓦数量级，对于雷达、远距离探测等重要应用，需要瓦级以上的大功率THz辐射源，回旋管是目前唯一可在THz波段实现大功率输出的器件，其输出功率可达千瓦量级。

The temperature gradient is larger in case ofussual half-zone model which has a uniform temperature distribution on the hot rod,andmodified half-zone model which has a non-uniform temperature distribution in the hotrod and negative radial temperature gradient near the axis of the hot rod.

模拟半浮区模型提出选择热传导系数与试验液体相当的材料作为热端棒材，使得热端内侧的轴向温度梯度接近于零。模拟半浮区模型的温度分布更接近于全浮区温度分布的一半。对于改型半浮区模型，选择热传导系数高于试验液体值一个数量级的材料作为热端棒材，使得热端温度分布不均匀，并且热端内侧温度高于外侧温度。

Therefore, we may get on with these matrices technique by using their special structure, and then reduce a quantitative level of the multiplications, and the research have definite real meaning.

对于此类问题，其相应的矩阵往往具有一些特殊的结构，因此，利用这些矩阵的特殊结构进行技巧性的处理，使矩阵的计算量降低一个数量级，这一问题的研究具有重要的理论意义和现实意义。
