Sun Sizhou published nearly 200 papers on mathematics research, education and teaching, which popularized many famous theorems, such as euler theorem's theorem, Stewart's theorem, Wiesenberg's inequality and so on. There are nearly 20 new achievements published in the name of "Theorem".

At the national elementary mathematics seminar held in 2007, Mr. Yang Zhi, the secretary general, made an inventory of the current situation of elementary mathematics research in China, especially referring to Sun Sizhou's research work (six people were named and commented nationwide).

He published a paper in Middle School Mathematics (Hubei) 1996, and published a new special point in the triangle-the regular point, which opened up a new field of elementary mathematics research. The original paper he wrote was repeatedly quoted, "forming a craze" (Professor Xu Jiahong's words). At present, a large group including university professors and middle school teachers are involved in this field. "Regular point" is Sun Sizhou's own name, which is taken from Qu Yuan's poem "Regular name, exquisite words". The special letter is "Z", taking the initial letter of "China".

Application of Mathematical Technology: Obtaining National Patents

To obtain a national invention patent, the technical principle adopted is mathematical principle, which is an application of exponential curve in production practice.
