TPD和FT-IR结果表明,在低压下PPh3-Rh/SiO2催化剂对氢甲酰化反应已具有相当的催化性能.","authors":[{"authorName":"朱何俊","id":"5943f46d-f000-4779-a624-1724ade880fd","originalAuthorName":"朱何俊"},{"authorName":"丁云杰","id":"b749c0e6-ea6f-4d32-8402-93e445700c6c","originalAuthorName":"丁云杰"},{"authorName":"严丽","id":"18d577bc-30a7-4e6c-b09b-845e084f14bd","originalAuthorName":"严丽"},{"authorName":"李显明","id":"a520bc9d-53ca-4195-9e0c-23c41678f0f4","originalAuthorName":"李显明"},{"authorName":"熊建民","id":"d7de669e-269b-4837-892b-8cb5549a0c7e","originalAuthorName":"熊建民"},{"authorName":"潘振栋","id":"75313672-4ff5-4ce8-8001-6a994aadc4f8","originalAuthorName":"潘振栋"},{"authorName":"<span

style=\"color:red\">江</span>丰水期河水pH值在7.4-8.4之间,为弱碱性;TDS平均含量为307 mg·L-1,高于珠江、长江干流.Ca2+和Mg2+是主要的阳离子,含量分别为61.64、10.98 mg·L-1,HCO3-是最主要的阴离子,含量范围在71.86-222.89 mg· L-1之间.离子组成分析和相关性分析表明,研究区河水离子主要受碳酸盐岩风化控制,存在部分玄武岩、砂岩的影响,硫酸参与了流域碳酸盐岩的风化,农业活动也有部分贡献.SO42-和NO3-相关性分析表明,北盘<span
