基于进入系统的时间，写操作具有幂等性(不管操作多少次结果都不变的性质，比如取绝对值的函数就具有幂等性)和交换性(操作顺序不影响结果，比如加法就具有交换性)。
Write operations are idempotent and commutative, based on the time they enter the system.
刷新缓存时会损失一些服务器加载数据和一些带宽；这并不违背基本的等幂性。
All you lose in flushing the cache is a little server load and some bandwidth; it does not violate underlying idempotency.
GET是应该没有副作用的操作，即所谓的等幂性属性。
GET is an operation that should be free of side effects, a property also known as idempotence.
由于PUT操作具有幂等性，因而如果结果不清可以进行重试，且不会有副作用(此情形相当于提交同一订单2次)。
As the PUT operation is idempotent, it can be retried if the result is unclear without causing unwanted effects (in this case, submitting the same order twice).
一个有限半群是满足左正则性条件的IC富足半群当且仅当它是一个幂等元形成左正则带的纯整超富足半群，但满足左正则性条件的无限IC富足半群不都是幂等元形成左正则带的纯整超富足半群。
A finite semigroup is an IC abundant semigroup satisfying the left rgularity condition if and only if it is an orthodox superabundant semigroup whose idempotents form a left regular band.
该模型具有数值可加型标准综合函数所具有的性质，即单调性、有界性和幂等性。
This model occupies some properties of additive standard synthesis function, namely, monotonic, limited and idempotent.

The simulation, with retransmission mechanisms such as the news of the power mode although there are some performance overhead but can guarantee service reliability.
