普通螺纹基本牙型尺寸及拧紧力矩.exe
一、概要
本软件功能主要是通过输入螺纹原始三角形高度P，螺栓规格（公称直径）d，材料的屈服应力σs，计算出公称应力截面积As、外螺纹小径d1、外螺纹小径d2、拧紧力矩T等参数。
开发本软件的原因主要有以下几点：
- 提高设计效率：通过这款软件，工程师可以快速计算螺纹的基本牙型尺寸和拧紧力矩，减少繁琐的手动计算，提高设计效率。
- 增强设计准确性：该软件基于严谨的数学模型和算法进行计算，避免了手动计算可能出现的错误，提高了设计的准确性。
- 方便易用：该软件具备友好的用户界面，使得用户可以便捷地进行操作，输入参数即可得到结果，省去了繁琐的手动计算过程。
二、技术细节
这段代码中主要完成的任务有：
- 读取用户输入的一些参数（例如螺纹的原始三角形高度P，螺栓规格（公称直径）d，材料的屈服应力σs等）。
- 计算螺纹的原始三角形高度P，外螺纹的小径d1，中径d2，以及螺栓的公称应力截面积As。
- 根据这些计算结果，进一步计算拧紧力矩T。
- 将所有的计算结果以特定格式（保留指定位数的小数）显示给用户。
代码技术细节：
self.significant_digit_lineEdit.text()：从用户界面获取需要保留的有效数字位数。float(self.P_lineEdit.text())，float(self.d_lineEdit.text())，float(self.s_lineEdit.text())：从用户界面读取输入的参数值，转换为浮点数。math.sqrt(3)：开平方根运算。"{:.{}f}".format(H, int(self.significant_digit_lineEdit.text()))：格式化输出，保留指定位数的小数。例如，如果用户输入要保留的位数为3，那么P会被格式化为类似"3.142"这样的形式。self.d1_lineEdit.setText(...)，self.d2_lineEdit.setText(...)，self.A_lineEdit.setText(...)，self.T_lineEdit.setText(...)等：将这些计算结果显示给用户。
