2. For mullion end surface milling, suitable for screwing connection type.
   中梃采用螺接工艺时，用于中梃型材端面的异型铣削；
3. Comparing the experimental results with those by the numerical simulation, it was noted that the maximum normal deflection of the vertical mullion of the glass curtain wall by the FE model quite agrees with the experimental results and they are all within the specifications of the standard criteria.
   通过对试验与有限元模拟结果的分析比较可以看出，该整体有限元模型主要受力杆件面法线方向最大挠度值的数值模拟结果与实验基本吻合，并在规范规定的容许值范围内。
4. Mullion structure in compression zone
   窗棂构造与挤压带
5. But the experimental results of the deflections near the lower end of the vertical mullion have obvious nonlinear relationship with the pressures and are quite different from those obtained by the numerical simulation.
   但试验结果在立柱下端节点处呈现明显的非线性变化，数值模拟结果与试验结果差别较大。
