Experimental studies on the influences of the deflected plates upon the oscillations were focused on the attenuations of sound pressures of the oscillations with the bent plates of various angles and lengths . the results show that the bent plates with angels of 30 ~ 60 and a length about an oscillating wavelength diminish the sound pressures notably . with the same angle of 45 , the half - wavelength bent plates diminish the pressures , and the one - wavelength or longer bent plates do better 结果表明,当折转角为30 60和折转长度( b )与振荡波长( )相当时( b / 1 . 0 ) ,折板具有显著的削弱振荡声压的效果;折转角45时,折板长度与振荡基频波长之比b /在0 . 5 ,折板就有削弱振荡声压的效果, b /在1 . 0或更大时削弱效果更佳。

The result shows that the profile which has a narrow region of peak value of tangential wind and a shorter radius of maximum wind , corresponds with the leaning northwest track and the maintenance or enhancement of intensity ; the profile which has a wide region of peak value of tangential wind and a longer radius of maximum wind , corresponds with the northern - turn track and the attenuation of intensity 结果表明:切向风速廓线上峰值区狭窄,最大风速半径较小时,台风呈西北方向移动的正常路径,强度易于维持;切向风速廓线上峰值区宽平,最大风速半径较大时,台风呈北折转向的异常路径,强度易于衰减。
