| 4 | Sound Insulation Performance of Structural Wood Wall Integrated with Wood Plastic Composite显示文摘The sound insulation performance is an important technical index for evaluating the physical property of the building wall.Three kinds of structural wood walls integrated with wood plastic composite(WPC)were designed.And the sound insulation performance of the walls was studied.The results showed that for the wall that constructed by the WPC as the wall studs,compared with the one that constructed by the pine wood as the wall studs,the deviation of their sound insulation was lower than±3 dB.The wall’s external panel material had significant effect on the wall’s sound insulation property,and the contribution of the wood-plastic panel to the sound insulation was much higher than that of the polyvinyl chloride(PVC)plastic hanging board.The surrounding sealing quality of the wall’s external panel material had an important influence on the sound insulation effect of the building wall,and the panel of the wood plastic interior wall had less influence on the sound insulation performance of the wall.Taking the sound-absorbing cotton or non-woven fabric as elastic strips was an effective technical measure to improve the sound insulation performance of the walls.The sound insulation was improved by 2.4 dB and 3.1dB respectively after the correction of pink noise spectrum,and increased by 2.8 dB and 3.6 dB respectively after the correction of traffic noise spectrum. | Xiaojun YANG Xiaolan TANG Lan MA Youfu SUN | 2019 | Journal of Bioresources and Bioproducts2019，4，2： | 0 |
| 5 | Seasonal variation of foliar δ^(13)C values and its indictor significance in Sabina przewalskii and Sabina chinensis显示文摘Seasonal variation of foliar δ13C values as well as proline,silicon,MDA and relative water content in Sabina przewalskii Kom.and S.chinensis (Lin.) Ant.were measured.The results show that foliar δ13C values were significantly different at different seasons:lower in winter but higher in summer.δ13C values were positively correlated with air temperature and soil temperature.This demonstrates that foliar δ13C of Sabina is a successful empirical indictor of temperature.Furthermore,foliar δ13C values were positively related to proline and silicon content,and negatively related to relative water content and MDA content.Compared with S.chinensis,S.przewalskii has higher δ13C values,proline and silicon content as well as lower MDA and relative water content.All these results provided strong evidence that it is feasible for δ13C to be regarded as another index to evaluate freezing tolerance of Sabina. | Tuo Chen HuiJuan Pei YouFu Zhang LongYing Wen HongGuan Tang YuanQing He | 2011 | Research in Cold and Arid Regions2011，3，2： | 0 |
