But the direction of position line error is overlooked in the textbook, with the result that the formula of standard error of transferred position line and running fix is mistaken.

但是，由于都忽视了船位线误差的方向性，因而引出的转移船位线误差估计的公式是错误的，由此得到的移线船位的精度估计公式也是错误的。

At present, laser process technology develops fast, since a laser light can obtain many good characteristics such as good direction, high energy density to focus the beam at a micrometer level, small pulse width ranging from dozens of Nanoseconds to dozens of Picoseconds, heating material immediately, decreasing heat effect on materials and so on.

由于激光束具有良好的方向性和高能量密度，可将光束聚焦到微米量级；由于激光束的脉冲宽度可达数十纳秒到数十皮秒，能够快速加热，对材料的热影响效应减小；因此，激光的以上优点为微加工提供了有利的条件，同时也促使激光加工技术迅速发展。
