By adopting the method , optimized runners and gate dimensions could be gained through iterative calculation according to the output results of the flowing simulation software after the location of the runners and cavities were fixed 利用该方法可在流道和型腔布置设定好后，根据流动模拟软件的输出结果，通过迭代计算得到优化的流道和浇口尺寸。
It has exact processing and heat treatment gate bushing , the part of heat can be delivered to the steel around the gate which make the plastic just enter wouldn ' t be frozen so quickly . it applies to crystalline materials 带精确加工及热处理的一体浇口司，能传递部分热量至浇口区域的金属，使得刚一进入型腔的塑料不至于迅速凝固，适于快速凝结的结晶性塑胶。
The fundamental mode beam has been gotten . the power output of u - folded laser without catalyzer , 3 . 5w has been gotten , while the corresponding unfolded laser , 4 . 5 w . this result indicates the availability of the forementioned design 在无催化剂的情况下，获得u型腔激光器输出功率3 . 5w和相同条件下的直线型激光器输出功率4 . 5w ，证实了该u型腔设计的可行性。
