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 .
