Cut file, sawing skills by learning the grip, standing position, body movements, and many other points force factors and the impact of the traditional grip of the emergence of file-grip handle to stand up after slightly outside the site of the palm, when a file cut Force, after the file handle a gradual shift,"hold" to "grasp", resulting in the introduction file enough; saw grip handle full point higher than the thrust of the saw blade to install center hole of about 30mm, the high point of thrust is likely to result in the bow saw On both sides of the swing, resulting in a broken saw blade and saw seam askew.

锉削、锯削技能的学习是受握法、站立部位、身体动作、作用力点等诸多因素的制约和影响的，传统的握法出现握锉柄后顶住部位稍偏离手心，锉削时一用力，锉柄逐渐后移，"握"变成"抓"，造成锉刀推出力度不足；满握锯柄的推力点高于锯条安装孔中心约30mm，偏高的推力点很容易造成锯弓向两侧摆动，造成锯条折断及锯缝歪斜。

The simulation results show that there is a remarkable reduction in buffer requirements and packet delay for DIASEAM in contrast to SEAM based on traditional VC-merge technique.
