"Find wallet"and"buy horses"are one-degree indeterminate linear equations, which can be solved by removed parameter, making no significant impact in the history of development of the indeterminate linear equation. 3、the problem of remainder arises with divining number. In sum, indeterminate problem borrowed from the eastern countries is to show Fibonacci's mathematical charm. He did not make in-depth study of the problem, but it is fascinating to the later European scholars, because these issues are interesting, and Fibonacci's solution is creative.
本论文通过对散布在《计算之书》各个章节中的三类不定问题进行系统梳理之后发现:《计算之书》"买鸟问题"的解法是"合金法",此方法是用来解答三种以上钱币配置问题整数解的情况;"捡钱包问题"和"买马问题"是一次不定方程组问题,解答过程相当于现今的一次方程组问题,通常通过"消参"即可解决,在历史上没有对不定分析问题的研究产生明显影响;而"剩余问题"是以占卜猜数问题的形式呈现计算过程,虽然斐波那契没有对不定问题进行深入研究,但正是因为这些问题的趣味性,以及斐波那契某些解法的独创性而引起以后欧洲学者对此类问题的兴趣,并由此将不定分析问题研究引入欧洲。

In this thesis, the phase diagram of Zn-Al binary system on 10~69.5 w% was reinvestigated by using differential scanning calorimeter, X-ray diffraction and pushrod dilatometer. The process of isothermal transformation during the aging of high-Aluminum-Zinc-based alloy was studied by using differential scanning calorimetry, and the aging behavior of the alloy was analyzed at the aspect of thermal analysis kinetics. The change of microstructure which the alloy was being heated was observed on high-temperature metallurgical microscope. The microstructure and wear-friction properties were compared among the alloys treated with several different heat treatment processes, and a model for heat treatment processes was proposed based on artificial neural network,so as to predict the relationship between friction coefficient and parameters of aging treatment such as aging temperature and time.
