activation record

基本解釋

The activation record contains all of the call-specific data for the function, including parameters and local variables.
活動(dòng)記錄包含了這個(gè)函數(shù)的所有與調(diào)用有關(guān)的數(shù)據(jù)，包括參數(shù)和本地變量。
This makes it easy for functions to know where their activation record is -- they are simply defined in terms of the stack pointer.
這對函數(shù)了解自己的活動(dòng)記錄在什么地方提供了方便 —— 它們可以使用堆棧指針的形式簡單地進(jìn)行定義。
Each call gets its own activation record, so each time it is called the variables get their own storage space within that activation record.
每個(gè)調(diào)用都有自己的活動(dòng)記錄，因此每次被調(diào)用時(shí)，變量都會(huì)在活動(dòng)記錄中獲得自己的存儲(chǔ)空間。
