查询词典 fluctuation

Based on thermal conduction theory, a thermal model is built up to get the effective thermal content and the effective thermal conductivity to be 1.0×10^(-3) W/K and 8.1 μJ/K, respectively, and the temperature-fluctuation noise is nearly 1.73×10^(-10)W/Hz(superscript 1/2). According to the device operating principle and energy equipartition theory of thermodynamics, the mechanical-thermal noise is 9.96×10^(-9) W/Hz(superscript 1/2), and the background noise is nearly 3.22×10^(-11)W/Hz(superscript 1/2), so that the normalized detectivity is deduced to be 9.03×10^6 cmHz(superscript 1/2)/W.

从理论上建立了器件的基本热模型，推导得到器件的等效热熔和等效热导分别为8.1μJ/K和1.0×10^(-3)W/K，温度噪声约为1.73×10^(-10)W/Hz(上标 1/2)；通过器件的工作机理和能量均分原理，推导得到热机械噪声的等效噪声功率约为9.96×10^(-9)W/Hz(上标 1/2)，器件的背景噪声约为3.22×10^(-11)W/Hz(上标 1/2)，从而得出器件的归一化探测率约为9.03×106cm。

Just as the relationship between the fluctuation of foreign trade and economic growth, the influence of the change of net trade volume among regions on regional economy is very complex: in the short term , the increase of surplus and the decrease of deficit are beneficial to increase the economic power of the region from the angle 0f external demand; in the long term, the increase of trade deficit in short period of time may increase the development strength of regional economy from the angle of strengthening the supply capacity of the region.

同时，与对国外贸易波动和经济增长的关系异常复杂一样，区域间净贸易量变化对区域经济的影响也十分复杂：从短期看，顺差扩大与逆差减小有利于从外部需求的角度去增强本区域的经济增长动力；从长期看，则短期的贸易逆差扩大有可能从增强本区域供给能力的角度去增强区域经济的发展后劲。
