一、技術(shù)總結(jié)
無。
二碍讨、英語總結(jié)(生詞：1)
1.overhead
(1)overhead: over-("above") + head(“top part, uppermost section”)
overhead的字面意思是：above the head,后來演變成"represent things situated above or metaphorically referring to additional costs".
adv. above the head.
adj. operating, lying, or comming from above. 示例: This room needs overhead lighting(這個房間需要頂燈).
n(c/u). business expenses(such as rent, insurance, or heating)not chargeable to a particular of the work.
(2)overhead costs vs direct costs
direct costs(直接支出/直接開銷/直接成本)：Costs that can be directly traced to a specific product(Example: raw materials, labor costs).
overhead costs(間接支出/間接開銷/間接成本治力，同 indirect costs): Costs that can be not directly traced to a specific product but are necessary for general operations(Example: rent, insurance, heating)蒙秒。
在計算機書籍里面勃黍，overhead 大多表示的也是“overhead costs”這個意思，會被籠統(tǒng)的翻譯成“開銷”晕讲。
Because the CPython interpreter process has a significant overhead, the Pool will consider each process in the pool a worker. If a worker has completed, it will be reused(《CPython Internals》第232頁)覆获。
