| 1. | While writes to volatile variables are guaranteed to be immediately visible to other threads , there is no way to render a read - modify - write sequence of operations atomic , meaning , for example , that a volatile variable cannot be used to reliably implement a mutex mutual exclusion lock or a counter
虽然可以保证其他变量可以立即看到对可变变量的写入，但无法呈现原子操作的读-修改-写顺序，这意味着（比如说）可变变量无法用来可靠地实现互斥（互斥锁定）或计数器。 |
