It is interesting to observe that the principle of operation for the "prism" coupler of fig. 3. 22b is being considered for extracting the output from lasers of the mesa type . 我們將看到圖322b的“棱鏡耦合器”工作原理正被考慮用來從臺面激光器獲得出,這是很有意義的。
The thermal expansion of liquids is the principle of operation here 液體溫度計的原理是液體的熱膨脹。
Typical for this principle of operation are remote thermometers 這種操作原理的典型應(yīng)用是遙感溫度計。
