在邮票艺术欣赏中,提起形式美来,人们自然会想起黄金分割。黄金分割原是希腊数学家发现的一条长与短最佳比例的公式,比例为1:1.618,最广泛应用于建筑上,后来应用到绘画、摄影等造型艺术中。人们往往运用简化的近似公式表达理想的长与宽的比例,大约是5:3或3:2最为适合,这与华罗庚的优选法比值相同,说明其中有合理的数列,有相互的数字间的和谐。这个比例对于人眼睛的视线范围来说,清晰而舒适。
In stamp art appreciation, the beauty of the form, people will naturally think of the golden section. Golden division was originally a Greek mathematician found a short and the best ratio of the formula, the ratio of 1: 1.618, the most widely used in architecture, and later applied to the painting, photography and other modeling arts. People often use a simplified approximate formula to express the ideal ratio of length to width, about 5: 3 or 3: 2 is the most suitable, which is the same as the ratio of Hua Luogeng optimal method, indicating that there is a reasonable number of sequences, there is mutual harmony between the numbers . This ratio is clear and comfortable for the human eye’s range of sight.
