In this dissertation, by applying the ideas of the mathematics mechanization, under the instruction of " AC=BD" theory of Professor Zhang Hongqing, we consider some methods seeking exact solutions to nonlinear partial differential equation arising from the fields of elasticity, fluid mechanics, aerodynamics, plasma physics, biophysics and chemical physics.

本文根据数学机械化的思想，在导师张鸿庆教授"AC=BD"理论的指导下，研究在弹性力学、流体力学、空气动力学、等离子体物理、生物物理和化学物理等现代科学技术中引出的非线性偏微分方程求精确解的方法。

Within 30-40 years of this first forage by Fitzhugh and co-workers into mathematical neuroscience whole communities of mathematicians, physicists, and engineers studying nonlinear dynamics of biological systems have started and matured.

在30-40年的这第一次饲料的菲茨休和同事到数学神经整个社区的数学家，物理学家和工程师的非线性动力学研究生物系统已经开始成熟了。

His research interests include mathematical modeling of biological systems, computational fluid and solid mechanics, multi-scale and instability analysis.

他的研究兴趣包括生物系统的数学模型，计算流体和固体力学，多尺度和稳定性分析。

Results show that the two systems are very similar in mathematical structure and diversity characteristics, and both are reasonable information systems, which fit well to the same distribution models, such as power law distribution and lognormal distribution.

分析结果表明，生物分类和土壤系统分类具有很高的相似性，有着相似的数学结构和多样性特征。

At the bookish assembly hosted by Secretary General Huang Chin-ying on January 3, Mr. Chang Pei-chen presented the first report on the Secrets of the 17-year Cicada written by Japanese Jin Yoshimura, a specialist of eco-mathematical model and biological evolution. The book was adapted from Yoshimura』s paper published in American Scientist in 1996, exploring the causes of evolution of magicicadas. Based on the duration of dormancy, magicicadas fall into two groups: the 13-year and 17-year periodical cicadas. Based on the principle of the survival of the fittest, as the lowest common multiple was larger, there were fewer groups proliferating at the same time to prevent damage of their ecological regularity as a result of hybridization.

1月3日读书会在黄晋英秘书长主持下，第一篇由张培臣先生报告《17年蝉之谜》，作者为日本人吉村仁，专攻生态数学模型与生物演化理论，本书改写自吉村仁於1996发表於《美国自然学家》期刊的论文，探讨质数蝉的演化缘由；依若虫期蛰伏於土壤中年份的不同，质数蝉大致可分为13年及17年两类，在天择情形下，因为最小公倍数比较大，同一时间的繁殖群相对比较少，可避免杂交而破坏其生态规律。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
