Studies on anti - hygroscopic property of coated xianglian granules .

香连颗粒薄膜包衣的防吸湿性研究。

The low relative humidity of the clear air helped to shrink hygroscopic aerosols , thus improving visibility .

那里清新空气和较低的相对湿度，也有助于收缩吸湿性的悬浮微粒，从而也改善了能见度。

The result showed that , the difference of hygroscopic and expansion of bamboo timber among three direction was distinct , and there was definited difference between the knot section and knotless section also .

结果表明，竹材各个方向上吸湿膨胀特性差异显著，且竹间部位和竹节部位的吸湿膨胀特性也有一定差异。
