representative coefficient

The correlation coefficient R and test of significance ( F) showed that r was closely related to Sr. The average absolute error of the 102 radii of positive ions was only 0.9 pm with the representative radii of ions, the relative error was 1.1%.

从相关系数R和回归方程的显著性检验（F）都说明r与S r密切相关，其中102种阳离子半径数据与具有代表性的离子半径参考值相比平均绝对误差仅0.9pm，相对误差1.1%。

By calculating air conditioning instant cold load in summer design day of the identical library construction presumptively located in several representative cities, its correspondent result is therefore obtained about cold load instantaneous coefficient and cold load index.

针对某图书馆建筑，分别按照几个代表性城市的气象条件进行夏季设计日的逐时空调冷负荷计算，求出了其相应的图书馆建筑冷负荷瞬时系数和冷负荷指标。
