XD-2003 strap machine is changed from XD-2002 machine which has a cast aluminium on the bed,making the screw,screwtube and speed reducer keeping concentric.the V-model manger on the bed is lower than the flat on which the speed reducer is fixed,the components are finished machining by machine tool.guaranteeing perpendicularity, degree of balance.speed reducer,screw and screwtube is fixed on the base,and the screwtube is in the mini-manger,then ensuring axis keeping concentric with sheath,screwtube feed opening has a chromium hard-wearing sheath,which can improve the lifetime of the screw and screwtube to threefold or to fourfold.

XD-2003 型塑料打包带机组，是在XD-2002型机组的机座上安装了一个铸铁机座，使螺杆，螺筒和减速机保持同心，座上的V型槽比安装减速机的平面低，其部件都是经过机床精加工完成的，保证了垂直度和平衡度。减速机和螺杆、螺筒置于底座上，且螺筒卡在微型槽内。确保轴与套保持同心，螺筒下料口处设有高铬耐磨衬套，这样可使螺杆、螺筒的寿命提高3-4倍。

我们还对二重对称扭秤的光子实验数据进行了分析，结果发现二倍频的效应为10~(-12)Nm 的量级，通过计算分析我们发现扭秤周围环境的不对称所引入的引力梯度效应是不容忽视的，因此针对喻家山人防山洞的具体情况，我们对光子实验的实际环境进行了模拟计算，理论分析结果表明对于二重对称的扭秤而言，环境不对称的影响引起的力矩效应为5.4940×10~(-10) Nm，对于四重对称的扭秤来说，效应为1.8668×10~(-11)Nm，可以看到随着扭秤对称性的增加，引力梯度的效应减小了一个数量级。
