The creation point of this article is: first, it broke the traditional idea that peasant workers are common village labor force and human resources. It comprehends the knowledge of human capital economics and the city peasant workers, pointing that peasant workers is the most important part in country human capital, is an extremely important question in fully building well-off society. Second, we calculated the peasant workers\' human capital revenue rate by using Mincer model. Thirdly, we point out that country human capital is the new developing region in China economy, enriched the theory of village economy, labor economy, human biology economy, human resource and human capital economy.

本文的创新点在于：一是首次将明瑟模型中计算人力资本收益率的方法应用到城市农民工当中，计算了城市农民工人力资本收益率；二是突破了农民工只是一般农村劳动力和人力资源的传统观念，将人力资本经济学内容同城市农民工相结合，提出城市农民工人力资本转化存在的可能性以及如何促成其完成该转化，提出了农民工是乡城人力资本的重要组成部分，而农民工人力资本转化是我国实现从人口大国到人力资源大国进而到人力资本大国的关键之所在；三提出了农民工人力资本是我国经济发展的新增长阈的新观点，丰富了农业与农村经济、劳动经济、人口生态经济、人力资源与人力资本经济等学科的理论。

The question of searching characteristic points or straight lines on moving rigid body is decomposed into two relatively independent sub-questions. The first one is to evaluate the characteristic of points and straight lines on moving rigid body, whose mathematics model is a kind of special non-differential max-mini optimal problem with inequality constraints. By the method of Saddle-point Programming and maximum entropy, the problem can be transformed as a differential optimal problem with single objective. The second oner is to search approximative character points or straight lines on moving rigid body within design space, whose mathematic model is nonlinear and non-differential problem with multiple constraints.
