Radiation losses are minimised by use of a well insulated locking swing ? aside cover that can be sealed when no baling is needed 转动式盖以优质绝热材料制成，在无须舀出和装料时能够密封熔炉，使热量损耗减少到最低。
2.
The radiation loss was obtained from the imaginary part of the complex propagation constant and the transition loss was calculated by two - dimension overlap integral method 基于计算得到的直弯波导的模场分布，采用二维重叠积分法计算了两者连接时的过渡损耗。
