The Effect of Leaves and Steel Support Cables on The Dynamic Properties of Northern Red Oak (Quercus rubra) with Co-Dominant Trunks
Trees Dynamics Co-Dominant
2014/11/26
Natural frequency and damping ratio were measured for ten forest grown northern red oak trees with co-dominant trunks. Steels support cables were installed in the canopies of five of the sample trees ...
以纳米TiO2为载体,通过浸渍法制备一系列改性Mn-Ce/TiO2脱硝催化剂.通过实验考察不同元素组分催化剂的脱硝活性,同时探讨金属氧化物掺杂对提高催化剂低温脱硝活性的机理.活性测试结果显示,Co掺杂能最有效地提高Mn-Ce/TiO2催化剂在低温段的SCR脱硝活性,在n(Co)∶ n(TiO2)=0.08~0.10、体积空速为35100 h-1的条件下,催化剂在120 ℃时就能达到80%以上的NO...
