若不朱层不侧厚其粘度必定补充，便当爆发不推纸毛，感化印品不朱色的陡均度，给是制卡不朱层不侧不厚及油不朱粘稠度不敷，印不入来的不朱色不离不侧不淡，印品触觉成果也不离不差。

However, the weighted geometric mean method is simpler than the weighted arithmetic mean method, and the former can keep the reciprocity of the improved judgement matrix without transformation.

理论分析表明：虽然这2种方法都具有收敛性，且均可对一致性较差的判断矩阵进行修正，但加权几何平均法比加权算术平均法简洁，且前者无需通过转换，直接保持了修正后的判断矩阵的互反性。

By using spectrophotometry method determinated the anthocyanindin and chlorophyll content in different parts of Prunus wilsonii leaves,results showed that,as time changes,anthocyanins content in different parts of the leaves showed a low-high-low change in trend,the analysis of variance,the difference is not significant,relations between anthocyanidin content in Prunus wilsonii leaves and the position of health was not obvious,anthocyanindin content in the same part are far greater than chlorophyll content,...

用分光光度法对紫叶稠李叶片不同部位的花青素和叶绿素进行了测定，结果表明，随着时间的变化，不同部位叶片的花青素均呈现低-高-低的变化趋势，经方差分析，差异性不显著，说明紫叶稠李叶片花青素含量跟着生的部位关系不明显；同一部位的花青素含量远远大于叶绿素含量，这也是紫叶稠李叶片在整个生长季呈现紫红色的原因。

Another batch of solutions was used to measure the content of water-insoluble glucan by anthrone method. The data was statistically analyzed by One-way ANOVA using SPSS13.0 software package.
