Research on rounding arithmetic for sweater armhole narrowing technique.

Base on the character of human arm, this paper finds the rule of narrowing technique, which is the height of narrowing for front panel is higher than back panel, and there is a few horizontal length in annhole base for fitted sweater, which needs the technique of narrowing point to narrow needle quickly. Furthermore, based on transform technique, it brings forward rounding arithmetic for narrowing technique, which can get narrowing technique by analyzing the remainder of whole narrowing needles and turns for armhole directly. Besides, the armhole shape can be divided into some parts, and the narrowing technique can also be got accordingly. [ABSTRACT FROM AUTHOR]
