radioisotope 中文意思是什麼
音標 ['reidiəu'aisətəup]
radioisotope
解釋
n. 名詞 【原子能】放射性同位素。adj. 形容詞 -isotopic
-
Given the decay rate of 26al, the lower initial ratio in the chondrules implies that these objects formed between one million and two million years after the creation of the refractory inclusions ( assuming that the radioisotope was indeed homogeneously distributed in the early solar system )
以鋁26的衰變速率估計，這些球粒的初始比值較低，表示它們是在耐火包體產生后100 ~ 200萬年才形成（假設鋁26在早期太陽系中確實是均勻分佈的） 。 -

The basic procedure of an interwell radiotracer test is, to inject a proper radioisotope tagged tracer material into the injector together with the injected fluid ; the tracer material will follow the injected fluid and go through the same path of injection fluid penetrating the formation ; finally the tracer material will be produced at the producer ; then, collecting samples at well head of producer, tracer response can be observed ; by analyzing the response of tracer, the information on dynamics of injection fluid and reservoir geology can be obtained
放射性井間示蹤測試的基本過程是：將一定量合適的放射性示蹤劑介入注入流體，使其通過注入井進入地層並跟隨注入流體穿越地層，最後被採油井采出；通過跟蹤監測示蹤劑在採油井上的響應，獲得注水井-採油井之間流體和地層的信息。 -
