因此,为了使 lambda 以您期望的方式工作,您需要以某种方式从其外部上下文中 “捕获” 所有这些自由变量,并将其保存以供日后使用,即使外部上下文将消失。也就是说,你需要找到你的 lambda 的闭包 (它使用的所有这些外部变量)并将它存储在其他地方(通过制作副本,或者为它们预先准备空间,除了堆栈之外的其他地方)。用于实...

The difference between a change in quantity demanded and a change in demand is that a change in: A. quantity demanded is caused by a change in a good's own current price, while a change in demand is caused by a change in some other variable, such as income, tastes, or expectations...

With multi-antenna synchronized global navigation satellite system (GNSS) receivers, the single difference (SD) between two antennas is able to eliminate both satellite and receiver clock error, thus it becomes necessary to reconsider the equivalency problem between the SD and double difference (DD) ...
