The breakpoint is determined mainly by the frequency and nearly independent of the transverse dimensions of tunnels and the polarization modes 电导率断点主要受传播频率的影响,而与巷道横截面尺寸和极化方式几乎无关。
Tower truss structure is a kind of rise independence structure , landscape orientation level load is the determine load , moreover wind load is main load to tower truss structure in all of level loads 塔桅结构是一种高度相对于横截面尺寸很大,水平风荷载起主要作用的自立式结构。
The cross - sectional size of the pbg cover is greatly reduced and its dimension is only 145 mm x 145 mm ( which is about 2 / 3 smaller than the cover designed by thevenot et al . , and 6 / 7 smaller than the one designed by qiu et al . ) 该覆层结构还大大缩小了尺寸,其横截面尺寸只有145mm 145mm ,该尺寸比thevenot等人设计的覆层减小了约2 3 ,比qiu等人设计的覆层减小了约6 7 。
