4.1.3 其他(1) Allowable Tower Deflection(inchs per 100 feet)塔计算中缺省的许用挠度为6 inchs/100 feet(1mm/200mm),如果采用其他值,需要输入指定的数值。注意:不同的工程项目或不同设备有不同的要求,进行计算前,必须检查输入值是否正确。(2) Wind Shape Factor如该值为“0”,则程序计算该值 18、;...
In this work, we aim to explore the impacts of trade liberalization and restriction measures on PV products, which could affect global PV trade, production, installation, clean power generation and carbon emissions reduction potential. This study constructs a trade flow matrix (TFM) of PV products...
