This is an untouched measuring way. The cameras are calibrated in the way of RAC two steps, first. With the polynomial interpolation, the pictures catched from the steel plate are treated to detect the edge in subpixel with a cross window arithmetic operators, which can fit non uniform illumination, keep the edge character and do filter in a better way. Three-dimensional scenery could be rebuilt from the two-dimensional pictures with the methods of least square fitting and contradictorily clairvoyance. Thus, the distance and its variance of two points in the given position of the plate can be achieved. It is expected that this study can provide a new and useful tool to the research on the theory of distortion of line heating.

The recursive least-squares estimation method is used to estimate the parameters in the modelled part of the robot dynamics, and the parameters is used to form the feedback control based upon the so-called"inverse system method". The unmodelled part of the robot dynamics is compensated by a learning control law. This not only increases the learning convergence speed and the control system robustness, but also extends the control method to non-repetitive tasks after sufficient learning.

But the glass-transition temperature of the polymer decreased to 96℃. When the cuing agent, PN was replaced by diphenyldiaminomethane, the V-0 rating could be achieved with the least content (3.68 wt% P and 0.83 wt% N) and Tg was increased to 139℃. The cyanate ester- containing PN was synthesized by phosphorus-containing PN and cyanogen bromide.
