value at best

The “use-by” or “best if used-by” date indicates the last day that the item is at its best quality as far as taste, texture, appearance, odor, and nutritional value. The decline after that is gradual.

“有效使用期”或“最好于该日期前使用”表示的是该产品在这个日期前，从口感、质地、外观、气味和营养价值等各方面保质着最佳质量，过期之后质量就会逐渐下降。

It is best to leave the property at this value, because enabling Aged timeout can have transactional implications when using JMS inside of EJBs.

最好为该属性保留此值，因为在EJB内部使用JMS时，启用过时超时可以获得事务本质。

Writing that constant over and over again is tedious at best, and error-prone if you try to type it in each time by hand instead of cutting and pasting the value.

一直重复写这个值最多只是乏味，但如果你每次都手动输入而不是采用复制、粘贴，那么很可能会出错。
