In addition, you have the option of handling runtime errors when a variable is not initialized.
另外，当一个变量尚未初始化时，您可以选择处理运行时错误。
This will result in PHP reporting a warning every time an uninitialized variable is used, each bad file access, and other (mostly) harmless errors, but might also represent a potential attack vector.
设置更改后，每当使用未初始化的变量、进行错误的文件访问及发生其他（大多数）无害错误时，PHP都会报告一条警告消息，但也存在这是一个潜在攻击矢量的可能性。
During the first few tries, we realized we'd made mistakes in setting our CLASSPATH variable, causing errors in the log files.
在首先的几次尝试当中，我们意识到我们在设置我们的CLASSPATH环境变量时范了错误，导致在日值文件中出现了一些错误信息。
Leaving them out, however, can often lead to programming errors because the initial value of the variable depends on the context in which it is declared.
但如果没有它们，很可能会引发编程错误，因为变量的初始值依赖于上下文。
If any errors are thrown, the error text is saved in the variable named 'error' and can then be accessed.
如果抛出任何错误，错误文本将保存在名为“error”的变量中，该变量可以被访问。
If there were any errors, we send the form back to the user with the errors in a template variable so that they can be used to highlight the problem.
如果有任何错误，我们都会将表单返回给用户，同时还有用来突出问题的模板变量中的错误。
For example even though at design time a variable of data type double can be mapped to a table column of type XML, the run time consequences are unpredictable and hence resulting in errors.
例如，虽然在运行时可以将double类型的变量映射到xml类型的表列，但是这可能导致不可预测的运行时结果，并因此而产生错误。
To generate user errors from procedures, you can use the SQLERROR variable to return an actual error string that caused the statement to fail to the calling application, as shown in Listing 16.
要从过程生成用户错误，可以使用SQLERROR变量检索一个实际的错误字符串，该错误字符串使语句无法作用于调用应用程序，如清单16所示。
So far research has blamed such errors on environmental and racial stereotypes, but new research published in Applied Cognitive Psychology adds another variable.
到目前为止的研究均把这类失误归咎于环境和种族这些老套原因，不过发表在《应用认知心理学》杂志上的新研究提出了另外的原因。
While this is convenient, it can lead to subtle errors in your code if you misspell a variable name.
虽然这样很方便，但如果拼错了变量名，可能会在代码中导致细微的错误。
A major cause of errors in speech recognition is the inaccurate detection of word bound-ary. Conventional methods can not work well in the condition of low SNR and variable background noise level.
词边界检测误差是语音识别中产生错误的主要原因之一，常规的检测算法在低信噪比尤其在背景噪声能量可变的环境下不能有效工作。
The iteration method with variable weights would be an effective method for the location of gross errors in the adjustment.
选择权迭代法是一种可望用于粗差定位的有效方法。
Most of subspace identification algorithms at home have errors in the errors-in-variable situation and close-loop situation.
目前很多先进算法均是基于多变量模型的，因此多变量闭环辨识也成为研究的热点之一。
