The results of test showed that SHW has clearly lower content of hot water and 1% NaOH extractives and clearly higher alcohol-benzene extractives, and slightly lower hemicellulose and ash, and roughly the same lignin and holocellulose contents by comparison with PHW.

实验的结果表明，与PHW相比SHW的热水抽出物及1%NaOH抽出物明显较低，而苯醇抽出物明显较高，半纤维素及灰分含量略低，木素和综纤维素含量则大体相当。

APMP produced form SHW has higher content of lignin and lower holocellulose, and lower tensile, burst and tear strength by comparison with PHW.

与PHW的APMP相比，SHW的APMP木素含量较高，而综纤维素含量较低，成纸的抗张强度、耐破强度和撕裂强度均较低。

It is also still too early to forecast the impact of pictorial health warning ( PHW) labels.

预测图片健康警语标签的影响也为时过早。
