It showed the correctness of the criteria of roundness error and relationship between the minimum zone circle, minimum circumscribed circle and maximum inscribed circle and the effectiveness of the methods for evaluation of roundness error.

Thus, evaluation of the minimum zone circle could be solved effectively.Three methods of assessment of roundness error were proposed in this dissertation. Based on the criteria of the minimum zone circle, minimum circumscribed circle and maximum inscribed circle and convex hull, a unified approach was proposed to evaluate roundness error of the minimum zone circle, minimum circumscribed circle and maximum inscribed circle. Evaluation of the minimum zone circle, minimum circumscribed circle and maximum inscribed circle was fulfilled with rotation based the contact pattern. The minimum circumscribed circle and maximum inscribed circle were evaluated with curvature and the curvature circle.

Statistic analysis result shows that the time step is the most important influence factor of simulation precision, and there is relation between simulation error and the setup value of restitution coefficient which the greater the setup value is, the less the simulation error is. Although there is no effect to the total contact time in the course of collision, the value of the time step decides the total contact step, and there is a logarithmic linear correlativity between them.

统计分析结果表明：计算时步是影响模拟精度最重要的因素；模拟误差还同恢复系数的设定值有关，设定值越大，模拟误差就越小；计算时步的大小虽然对碰撞过程的总接触时间影响不大，但是却决定了碰撞过程的总接触时步数，二者之间存在对数线性相关关系

Only two papers known to the author discussed the possible relationship between the estimates of Km and Vmax. Colquhoun (196 9) found a strong positive correlation between these estimates in a simulation study. Subsequently, Oliver (1970) examined this relationship by the asymptotic variance-covariance matrices. These simulation and mathematical analyses were based on the assumption that the substrate concentration is error-free, with the error confined to the reaction velocity. In addition, their work was confined to the several estimation methods.

就作者所知，在本研究发表之前仅有两篇文章讨论过估计值之间的相关性。1969年，Colquhoun通过计算机仿真，发现了估计值之间存在正相关关系，1970年，Oliver用渐近方差-协方差矩阵检验了这一点，但是他们的发现有很大的局限性，其一是限于仅反应速度的测量值有误差这一种情况，其二是限于某几种估计方法。

The idea that there is such a thing as animal intentionality, and that it is a purely biological phenomenon, has much potential interest for thinking about human beings: among other things, it raises the question of whether other 'communitarian' accounts of human intentionality might not be guilty of the same error as Davidson's—the error of cutting too deep.

存在这样一个东西作为动物意向性'的观念，这是一个纯粹生物现象，对思考人来说有很多潜在的interest好处；在其他事物中，这提出一个问题，是否其他'communitarian『共产主义』'对人的意向性的说明就不会有同样于Davidson的错误。
