Meanwhile, by using interval estimation instead of the conventional point estimation, the lower and upper confidence limits, the confidence intervals of structure concrete strength are derived.
运用区间估计方法代替传统的点估计方法，导出结构混凝土强度的置信上限、下限和置信区间。

Based on this, the formulas for calculating, according to the minimum condition, the measuring error limits of straightness have been derived.
在这基础上，推导出了按最小条件评定直线度的极限测量误差的计算式。

The other is the "theory of the limits "which is naturally derived from the pursuit to "the effect of aesthetic" creation principle.
