The reason is many sided: 1 student and parent think " miscalculate " irrespective, as long as next time attentive dot went. The student allows to use a calculator in 2 education, the student had to the calculator depend on, often abandon when encountering seemingly complex calculation think, use a calculator directly, for instance 618, do not know to change brief into 13, achieve a result with the calculator directly however 0.33. Phase of 3 high school trains a student " put forward, analysis and the ability that solve a problem " the demand is higher and higher, of the train of thought that inscribes to solution in classroom education, thoughtway many somes more tuitional, and to operation ability, because the student has certain base, loosened with respect to some then. 4 emphasizes the training of all sorts of thinking ability overly, the training of operation ability has the suspicion that should try education it seems that, this also is one of reasons. The operation in 5 maths, no matter be numeric computation, return be algebraic type to be out of shape figure, photograph of the train of thought that inscribes with new knowledge, new solution, skill is compared and character, appear more as dry as a chip, the student does not have interest.

原因是多方面的：1学生和家长都认为"算错了"没关系，只要下次细心点就行了。2教学中答应学生使用计算器，学生对计算器有了依靠，在碰到貌似复杂的计算时往往舍弃思索，直接用计算器，比如618，不知化简成13，而是直接用计算器获得结果0.33.3高中阶段培养学生"提出、分析和解决新问题的能力"的要求越来越高，课堂教学中对解题的思路、思想方法的讲授多一些，而对于运算能力，因为学生都有一定的基础，于是就有些放松了。4过分强调各种思维能力的练习，运算能力的练习似乎有应试教育的嫌疑，这也是原因之一。5数学中的运算，不管是数值计算，还是代数式的变形演算，和新的知识、新的解题的思路、技巧相比较而言，显得比较枯燥，学生没有喜好。

Now there are many techniques to automatically generate software testing data, but most of the methods only deal with numeric value. In fact the non-numeric data, such as character string, are widely used, and it limits the application of software testing.

目前已有许多测试数据自动生成的方法，但大多只涉及数值型测试数据的产生及选取原则，在实际应用中非数值型数据使用相当普遍，如字符串数据，这在一定程度上限制了软件测试技术的应用。
