While this approach is not without merit, it can be difficult to accurately reproduce the asynchronous processing of user interface code.
虽然这种方法不是没有好处，但是要精确的复写出与用户界面异步交互的代码却很难。
Full coverage was very expensive and difficult to achieve, because we had to hand-inspect our code to determine which lines were and were not hit by the test.
完全的覆盖是非常昂贵的并且很难达到，因为我们必须要手工的检查我们的代码以确定哪一行代码没有被测试覆盖到。
The generated code is not to our liking, so we have to do a large number of implementation changes, which makes keeping the model synchronized with the application very difficult.
所生成的代码不合我们的意，因此我们要进行大量实现更改，这使得我们很难保持模型与应用程序的同步性。
Even when such systems are available, the test data may not be suitable for exercising all code paths; that is, it may be difficult to simulate some error conditions.
即使在这些系统可用时，测试数据也可能不适于使用所有代码路径；也就是说，模拟一些错误条件可能会很困难。
In principle, creating such code is not particularly difficult, but can be somewhat tedious and error prone to write, especially if the data object is large and contains nested objects and arrays.
原则上，创建此类代码不是特别困难，但可能让人感到有些枯燥无味，而且在编写时也容易出错，特别是在数据对象比较大并包含嵌入的对象和数组时。
That's not too difficult to do, but the implementation code becomes fairly complex.
这并不太难做到，但是实现代码将变得相当复杂。
Refactor when the code is difficult to understand and the team is not sure of what it does.
当代码难于理解，并且团队不能确定它做什么的时候进行重构。
The good news is that the source code of this functionality is available and is not too difficult to adapt to other environments.
幸运的是，这个功能的源代码可供使用，并且调整它以适应其他环境并不困难。
Not only is that process slow, but the code is also difficult to understand and maintain.
该过程不仅速度慢，而且代码也难于理解和维护。
When the source code is not available, it's even more difficult.
当源代码不可用时，回溯变得更加困难。
Not only is it difficult to code them correctly, but the timing of finalization is not deterministic, and there is no guarantee that finalizers will ever even run.
终结器不仅难以编写正确，终结的定时也是不确定的，并且不能保证终结器最终会运行。
代码并不难。
Code analyzers, refactoring tools and automated refactorings, formatters and more, are difficult, if not impossible, to write in Ruby, because there is no way to parse Ruby source with Ruby code.
用Ruby写代码分析、重构工具和自动重构、格式程序等等甚至更多的工具并非不可能，但是很困难，因为还没有用Ruby代码分析Ruby源码的先例。
For a cyclic code, it is difficult to find the set of it's covering polynomials. We have not had a systematic method to find it.
给定一个循环码，求取它的覆盖多项式集合目前尚无系统的方法。
Copy machine can not blame difficult, not drag, can not search, IE can not open any manner JS code (only the last 68 minutes of the)?
机器怪疑难无法拷贝，无法拖动，无法搜索，IE打不开任何地JS代码(只有最后68分了)？
In general, using embedded code blocks for complex programming logic is not a best practice, because when the code is mixed on the page with markup, it can be difficult to debug and maintain.
一般情况下，将嵌入式代码块用于复杂的编程逻辑并不是最佳做法，因为当页中的代码与标记混合时，很难进行调试和维护。
