There are many problems in the carling forming and unloading processes such as expand and shrink of U section wall, the torsion of U section and the warp of carling head.

针对纵梁冲压成形及卸载后发生的U型截面侧壁的外扩、内缩、扭转以及纵向端头翘曲等问题，首先分析了纵梁的成形及回弹变形机理，利用仿真分析软件KMAS进行了数值模拟并采用半解析、半实验方法研究了纵梁底面翘曲，找出模具结构的最佳方案。

There are many problems in the carling forming and unloading processes such as expand and shrink of U section wall, the torsion of U section and the warp of carling head. These problems are concerned by the carling factories and do not solved for a long time. The mechanism of the carling forming and spring back is analyzed. The carling forming and spring back processes are simulated by KMAS software. The warp of carling underside is researched by half analytic and half experiment method and the best scheme is found by this method.

Also, it is derived from theory that the gas-liquid flow in the inverse U tube is stable in all the flow pattern map.

然后从理论上对倒U型管内气液流动进行稳定性分析，得出倒U型管内气液流动在全流型范围内处于稳态。

In terms of luminance performance of BLUs, there shows no much difference between V-cut and U-cut microstructures from simulation results. However, U-cut microstructure outperforms V-cut one in luminance uniformity.

另外在整体BLU辉度并未因入光侧添加微结构而有大幅的变化及差异的前提下，U-cut纵沟微结构的使用效果会比V-cut纵沟微结构来的好，除了在入光测量测点均齐度提升略胜一筹外，其入光侧明暗不均问题亦可处理地更为淡化，以达到光学及品味之最佳化。

Three control factors, involving in the optimization process: the pitch and depth of both V-cut and U-cut, and angle and radius for V-cut and U-cut, respectively, are the same as full factorial experiment method.
