The first processors that supported concurrency provided atomic test-and-set operations, which generally operated on a single bit.
支持并发的第一个处理器提供原子的测试并设置操作,通常在单位上运行这项操作。
It is a commonly held belief that you do not need to acquire a lock to simply read an object's fields, especially since the JLS guarantees that 32-bit reads will be atomic.
有一种普遍的观点是,如果只是要读一个对象的字段,不需要请求加锁,尤其是在JLS保证了32位读操作的原子性的情况下,它更是如此。
Permissions were based on masking a 32-bit integer — the example application and requirements would have needed at least 64 bits to handle the required atomic permissions.
各种权限都基于屏蔽一个32位整数——示例应用程序和要求至少需要64位才能处理所需的原子权限。
One is a little bit higher and one is a little bit lower than they are in the atomic situation.
一个有点高,一个有点低,相比他们是原子状态的情景而言。
It turns out that the antibonding orbital is a little bit higher from the atomic orbital level than the bonding orbital is lower.
这证明了,反键轨道,比原子轨道高,成键轨道比原子轨道第。
