其绕虚轴的侧向屈曲和可能出现的弯扭屈曲在现行规范和研究文献中尚未有详尽的讨论。 |
| 4. | The symmetric values about the imaginary axis of zero - poles which the unstable process lies in the open and closed right - half plane are defined as their mirror - injection
非稳定过程在开右半平面的零极点关于虚轴的对称值称为该零极点的镜像映射。 |
| 5. | Simulation result shows that although all structural error of virtual axis machine tool can not be identified completely while the moving platform moves inside its working space , the moving platform kinematic accuracy is fulfilled inside the whole working space after error compensation
仿真结果表明，虽然在虚轴机床的工作空间里无法将其可能存在的结构误差全部求出来，但计算结果完全可以满足机床在工作空间里的运动精度要求。 |
| 6. | First we consider the spectral properties of the operator corresponding to this system and obtain that all points on the imaginary axis except for zero belong to resolvent set of the operator , zero is an eigenvalue of the operator and its adjoint operator with geometric multiplicity one
先讨论了对应于该系统的主算子的谱特征并且得到了在虚轴上除了0点外其它所有点都属于该主算子的豫解集， 0是该主算子及其共轭算子几何重数为1的特征值。 |
| 7. | According to the elastic bucking theory this paper reviews and compares the calculations that such member bend around the reat axis and the hollow axis as well as bend with torsion around the hollow axis . here this paper presents a formula of calculating b used in with the h - shaped anglicizing element . meanwhile , this paper deduces out a formula of calculating b . by , which the member could be controlled to only buckle around the real axis
本文根据弹性屈曲理论对双肢格构式单轴对称缀板柱绕实轴、虚轴以及弯扭屈曲进行了计算分析和比较，提出了绕虚轴侧向屈曲的换算长细比_ ( oy ) = ( y ~ 2 + l ~ 2 ) ~ ( 1 / 2 )中的值用h计算单元指出的计算公式，同时推导出了单轴对称缀板柱只出现绕实轴弯曲屈曲的最小肢间间距b 。 |
