A large number of relaxation schemes for feature mapping, claimed to be invariant to transformation, have been reported. However, most of them can deal with transfor-mations involving only rotation and translation, but not scaling. To stay away from the issue of scaling, unrealistic assumptions have to be imposed, such as the conjectures that range data are available so that objects can be rescaled before mapping, and that object shapes are complete so that ratios between object shapes and prototypes can be figured out beforehand. In this paper, we propose a relaxation scheme which is able to be in-variant at a time to rotation, translation, as well as scaling.

截至目前为止已有不少供几何特徵匹配用之松弛法架构被提出来，这些架构虽然宣称可以对空间转移具有不变性，但是实际上，大部分只能处理和旋转及平移有关的转移，对於具有尺度因素的转换泽尽量避免，因此，便有各种不同的假设被加诸於所考虑的问题，例如假设我们已知景深值，因此可以先将物件的尺度正规化后再比对，或者假设物形式晚整的，於是物形和模型间的尺度比率事先可以推知。

These survived periodic orbits though scarce in a chaotic system, form the invariant skeleton of the phase space and possess important characters relating to the constants of motion and the quantal levels.

但这些存活下来的周期轨迹是体系相空间的运动骨架。

This paper reviews the control theories used for robot in details. The interative and nonlinear torques of the traditional robots at the joint axis are reduced by a factor of gear ratio. The complicated arm dynamics is approximated to a linear, time-invariant model. The robot can be controlled by using local, decoupled PID's controller at each joint.

The results show that with the increase of deformation strains and thinning of Fe-Cr fibers, the saturation magnetization are about 140 A·m2/kg constantly, and the remanent magnetism and coercivity increase gradually.The magnetic properties of Fe-Cr fibers are invariant when the Fe-Cr fibers were preserved in absolute alcohol or air for more than 1 a. After Fe-Cr fibers heated in air at temperature higher than 300 ℃ for 1 h, the Fe-Cr fibers transform from ferromagnetic α-solution to paramagnetic2O3, and the saturation magnetization of samples decreases remarkably. With the increase of deformation strains, the thermal stability of thinner Fe-Cr fibers decreases.
