This paper discusses the theory on the measurement of human capital value from the angle of economy and accounting on the basis of discriminating between the value and price of human capital. The author considered that the value of human capital should be adopted into the value information system of a enterprise and analysis on the value be contained in the analysis of a enterprise's value to meet the demanders.

This paper criticizes 4 specious propositions about current controversy on theory of value:（1）the proposition that labor is the only resource of value needn't to be verified;(2) value is created by live labor, but distributed by ownerships of production factors;(3) value is determined in the process of production, but realized in the circulation;(4) value is a kind of social relationship, where there is no atom of use-value.

论文提要本文剖析了当前有关价值争论中的4个似是而非的命题：（1）劳动是价值的惟一源泉无需证明；（2）价值是由活劳动创造的，价值的分配是按生产要素所有权进行的；（3）价值是在生产过程中决定的，在流通中实现的；（4）价值是一种社会关系，其中不包含任何使用价值原子。

Aimed at the problem of choosing the initial value when the Newton method is used to compute the controlling unstable equilibrium point, a practical and rigorous solving scheme was presented: by identifying the controlling load bus of the given fault, and using the Thevenin equivalent circuit to represent the rest of the system at the state of the post disturbance stable equilibrium point, using the steady equivalent circuit to represent the induction motor in composite load, and then using the torque characteristics of induction motor, a point near the CUEP is gained to be the initial value. The second order normal forms was used to approximate the stable manifold of CUEP, and the local approximating boundary of the region of attraction of the post disturbance stable equilibrium point was gained. Then just by simulating the state of the system at the fault clearing time, the transient voltage stability of the system could be determined.

针对采用牛顿法求取故障后系统主导不稳定平衡点(controlling unstable equilibrium point，CUEP)存在的初值选取难题，提出一种实用但不失严谨的解决方案：通过识别给定故障的主导负荷母线，对主导负荷母线以外系统由故障后稳定平衡点处的状态进行戴维南等值，对负荷中感应电动机部分采用其稳态等值电路，再由感应电动机的转矩特性求得CUEP附近的一个点作为近似的CUEP，以此为迭代初值可靠求得CUEP；采用二阶正规型来近似CUEP的稳定流形的方法求得近似的局部吸引域边界；由仿真得到故障清除时刻系统的状态并根据该状态是否位于吸引域内判断系统的暂态电压稳定性。
