二、(一)請計算一部耗乏區為20 mm之純鍺偵檢器全能峰（full energy peak）之本質偵檢效率（intrinsic efficiency），假設純鍺之加馬射線之衰減係數為 0.005 cm2 /g，鍺之密度為5.5 g/cm3，請問0.6 MeV加馬射線全能峰之本質偵檢效率為何？

一、英譯中：Translate the following passage into Chinese Increasingly, tourists of today are shunning enclave holidays. These are holidays where they are whisked from the airport to a resort to hibernate for a week or so before they are whisked back to the airport for the journey home. Today’s tourists want to see and get to know the country in which they are holidaying. They want to meet the people, eat what they eat, experience how they live, and get to know their culture.
