系列试验的参数估计法

《国外数学名著系列(续一)(影印版)40:模型参数估计的反问题理论与方法》主要内容：Prompted by recent developments in inverse theory, Inverse Problem Theory and Methods for Model Parameter Estimation is a completely rewritten version of a 1987 book by the same author. In this version there are many algorithmic details for Monte Carlo methods, least- squares discrete problems, and least-squares problems involving functions. In addition, some notions are clarified, the role of optimization techniques is underplayed, and Monte Carlo methods are taken much more seriously. The first part of the book deals exclusively with discrete inverse problems with afinite number of parameters, while the second part of the book deals with general inverse problems.

The book is directed to all scientists, including applied mathematicians, facing the problem of quantitative interpretation of experimental data in fields such as physics, chemistry, biology, image processing, and information sciences. Considerable effort has been made so that this book can serve either as a reference manual for researchers or as a textbook in a course for undergraduate or graduate students.

牵引试验的目的是测定拖拉机各项牵引指标和经济指标，画出牵引特性曲线。对于新试制的拖拉机、新引进的样机以及原有产品的质量检查，都要进行牵引试验，画出牵引特性曲线，用于指导设计、生产和使用。

牵引试验的测试方法有定距离法和定时间法两种。采用定距离法作牵引试验是指拖拉机在调整好的工况下，使其稳定行驶完规定的距离，测量并记录各项参数的实测数据；然后，调整到另一工况，重复上述测量，如此逐点进行，直至完成全部试验。定时间法则是使拖拉机在规定的路面上，不停车，连续改变工况进行试验，每改变一次工况，稳定后，随即在规定时间内：测取并记录各参数的平均值。通常走完全程，便完成一个挡位的测量。
