本模块的输入项包括：（1）特征峰的峰高、面积、浓度；（2）用户设定的计算公式。

为避免同样的计算公式，在不同样品的诊断比值计算过程中的多次重复输入。本系统设计了一个全局诊断公式表。如果样品的待计算的诊断比值公式在全局诊断公式表中存在，则用户可以直接在全局表中勾选，即可实现将该所选的公式复制到当前的样品中诊断比值列表中。对于待测样品新增加的而全局表中没有的诊断比值公式，系统也会在全局比值公式表中保存一份，以备以后的重复使用。

-The input modules include: (1) the characteristic peaks of the peak height, area, concentration　(2) the formula for calculating the user settings. In order to avoid the same formula in different diagnosis samples ratio calculated in the process of repeated input. The system design of a global diagnosis of the formula table. If the sample to be calculated in the ratio of the formula in the Global diagnostic diagnostic formula table exists, the user can directly check in the overall table, you realize that the selected formula copied to the current diagnosis of the ratio of the sample list. The new sample and the overall table, there is no diagnostic ratio formula, the system will be in the overall ratio of formula to keep a table to prepare for future reuse.
