实验表明，使用计数器不仅能提高实验效率，而且实验结果更精确。
The experiment suggests that the use of the current counters can not only enhance the experimental efficiency but also give a more accurate experimental result.
定时器模块包括四个通道，定时器0 ~TIMER3，这让您能够轻松地实现一个使用计数方案。

它代替基于10计数系统的——如十进位制- - - - -十六进制的系统使用计数系统的16来传达信息。
Instead of a count system based on 10-such as the decimal system-the hexadecimal system USES a count system of 16 to convey information.
为负载测试指定使用计数器的临界值规则：临界值规则是设定在单独之效能计数器上的规则，用来监视负载测试期间的系统资源使用。
Specify a threshold rule using counters for your load test: a threshold rule is a rule that is set on an individual performance counter to monitor system resource usage during a load test.
为了检验这些儿童是真的使用计数器的数目而不是单纯对研究者的行为模式进行模仿，研究者把一些小棍子混在一起，并让这些儿童将计数器摆放成干扰的小棍子分布的样子。
To check that they were using the number of the counters, rather than mimicking their pattern, the researchers banged sticks together and asked them to "make the counters like the noises".
不过，当您使用某个采用引用计数的数据结构时，您必须记得运行引用计数函数。
However, you must remember to run the reference counting functions whenever you are using a reference-counted data structure.
由于引用计数是如此简单，大部分程序员都自已去实现它，而不是使用库。
Since reference counting is so simple, most programmers implement it themselves rather than using libraries.
在同时使用了垃圾收集和引用计数的混合系统中，将会发生泄漏，因为系统不能正确识别循环引用。
In a hybrid system, where both garbage collection and reference counting are being used, leaks occur because the system fails to identify a circular reference.
另外，内置函数和第三方的库不会知道或者可以使用您的引用计数机制。
Also, built-in functions and third-party libraries will not know about or be able to use your reference-counting mechanism.
InfoQ：MacRuby允许使用AOT编译Ruby代码，那么，有没有可能不使用垃圾收集器，即能否仅仅使用Objective - c的引用计数内存管理？
InfoQ: MacRuby allows to AOT compile Ruby code - but is it possible to opt out of the Garbage Collector, ie. is there a way to just use Objective-C's reference counting memory management?
在使用计算机对外部脉冲进行计数的过程中，由于干扰脉冲的存在，计算机得到的脉冲数往往比实际的脉冲数要多。
When we use computer to count the number of external pulse, because of disturbing pulses the number of pulses that computer receives is bigger than its actual number.
不使用引用计数为对象，其中可以得到复杂和容易出现的错误。
Doesn't use reference counting for objects which can get complex and error prone.
首先，这个程序使用第22章介绍的Py _ DECREF函数，减小了从Python传来的对象的引用计数。
First, this program also decrements the reference count on objects passed to it from Python, using the Py_DECREF call introduced in Chapter 22.
