According to the second method,we can judge that if error of closure of horizon in many detail unclosed traverse exceed 40 second,if error of closure of angles exceed 40n1 second.
按照方法二可计算出各条图根支导线的测站点圆周角闭合差是否超过±40″,各条支导线的角度闭合差fβj是否超过40 n1″,测角中误差m角平是否超过21。

Bamboo strip unfolding rate of onefourth circumference is 99% and that of one-third is 52% (the top of bamboo culm being 8%,the middle 75% and the bottom 72% ), but bamboo strips with 5/12 circumference are allbroken.
结果表明：①采用本方法可展平”一定圆周弧度的毛竹片。
