收益分配制度安排与企业类型的对应性问题

目前,学术界对按劳分配、按资分配和按知分配三种制度的评述存在三个缺陷:第一,对收益分配制度安排要解决的核心问题的认识比较模糊;第二,似乎按知分配适合于任何类型的企业;第三,对收益分配形式的配合问题重视不够。

Spectra of Off-diagonal Infinite-Dimensional Hamiltonian Operators and Their Applications to Plane Elasticity Problems

In the present paper, the spectrums of off-diagonal infinite-dimensional Hamiltonian operators are studied. At first, we prove that the spectrum, the continuous-spectrum, and the union of the point-spectrum and residual- spectrum of the operators are symmetric with respect to real axis and imaginary axis. Then for the purpose of reducing the dimension of the studied problems, the spectrums of the operators are expressed by the spectrums of the product of two self-adjoint operators in state spac,3. At last, the above-mentioned results are applied to plane elasticity problems, which shows the practicability of the results.

由一组二维轮廓线重构三维物体

提出了一种由轮廓线定义的任意复杂形状的物体的三维重构的通用方法，对于其中的两个难点（对应性问题和分支问题）分别给了解法，为了使提出了方法适用于含洞型（奇异型）分支问题，先用包围盒测试轮廓线之间的拓扑包含关系，再用一种法则确定相邻切片上轮廓线之间的对庆关系，将分支问题分解为非奇异型或奇异型的单分支问题，此方法被用际断面解剖学中的人脑蝶鞍区切片的三维重构中，得到非常满意的效果。
