默认情况下，每500毫秒收集一次计数器。
否则，如果两个线程试图同时执行增加，操作的不幸交叉将导致计数器只被实现了一次，而不是被实现两次。
Otherwise, if two threads tried to execute the increment simultaneously, an unlucky interleaving of operations would result in the counter being incremented only once, instead of twice.
默认情况下，这个计数器从1开始，每执行一次循环递增一次。
By default, this counter starts at 1 and is incremented each time the loop is taken.
多数监控器的计数器是累计的，反映从您的会话(您从中发布db 2命令)中最后一次快照监控器复位起的具体活动的总数。
Most of the monitor counters are cumulative, reflecting the total count of a particular activity since the last snapshot monitor reset within your session from which you are issuing your db2 command.
如果你总是把“youknow”挂在嘴边，就在手腕上戴个高尔夫计数器，每当意识到自己说一次“youknow”时就按一下计数键。
If you say "you know" too much, wear a golf counter on your wrist, and press the button whenever you catch yourself saying "you know".
对于这种情况，通常需要3次循环才能执行一次更新(首次更新尝试失败；获取当前的计数器值；最后成功更新)。
In that case, it will usually cost three round-trips to do an update (the initial failed update attempt, the fetch of the current counter value, and the final successful update).
我经常尝试仔细检查我第一次添加到报告的计数器。
I often try to double-check a counter the first time I add it to a report.
倘若嫌戴腕部计数器令人难堪，那么就在每说一次“youknow”时把口袋里的一张纸弄破一个小洞。
If a wrist counter is embarrassing, then make a small tear in a piece of paper in your pocket each time you say "you know".
计数器跟集合相似，除了一点，就是如果计数器中元素出现的次数超过一次，计数器会记录下出现的次数。
Counter is like a set, except that if an element appears more than once, the Counter keeps track of how many times it appears.
每当计数器被时钟脉冲触发一次时，计数器输出的二进制数便累减1。
The counter output, which represents a binary number, decreases by 1 any time the counter is triggered by a pulse .
每循环一次，外部循环都使循环计数器变量递减一次。
The outer loop decrements a loop counter variable each time through the loop.
再点击一次这个按钮，将停止计数器。
该计数器每5分钟(缺省)读取一次。
