诺谟图(Nomogram)是近代发展起来的一个数学分支,最早是由一些工程师为了简化计算工作创造出来的。图的结构以正交坐标系下若干组线组成的网络图为主要形式。 1884年法国的青年(22岁)桥梁工程师奥根(O'cagne)创立了以平行坐标系下的贯线图(或共线图),这是图算学的精髓,从此以后,贯线图(Alignment)才真正成为一门独立的学科。应该肯定,在图算学的开拓与发展过程中,奥根做出过卓越的贡献。为此,我国著名科学家茅以升、罗河、孙克定建议,并经全国图算学联络委员会决定,于1984年10月14～17日在青岛市举行了全国图算学百周年纪念会。参加这次纪念会的有来自全国二十三个省、市、自治区的103名代表。
Nomogram is a mathematical branch developed in modern times. It was first created by some engineers to simplify the calculation work. The structure of the graph takes the network diagram composed of several groups of lines under the orthogonal coordinate system as the main form. In 1884, the bridge engineer O'Cagne, a young French engineer (22 years old), founded a line drawing (or collinear chart) in parallel coordinate system. This is the essence of chart arithmetic. Since then, Alignment) really become an independent discipline. It should be affirmed that, in the course of the development and development of graph arithmetic, Agen made outstanding contributions. To this end, Mao Yisheng, Luo He and Sun Keding, the famous scientists in our country, proposed and held the National Centenary of Education of Chinese Studies on October 14 and 17, 1984 in Qingdao. There were 103 representatives from 23 provinces, cities and autonomous regions nationwide attending this commemorative meeting.
