波動轉化帶 的英文怎麼說
中文拼音 [bōdòngzhuǎnhuàdài]
波動轉化帶
英文
fluctuating zone of transition-
The phenomena of initial disturbance vorticity translating into spiral bands is most evidently for it locating at the periphery of radius of maximum wind ( rmw ), near rmw next and the spiral bands vanish when it is positioned in the inner core region. indicating that the farther the distance from the tc center, the more distinctly the spiral bands and the opposite is true
初始圓形擾動渦度場轉化為螺旋臂渦量帶的現象是初始擾動位於渦旋最大風速半徑（ rmw ）外圍最顯著，其次是rmw附近，當擾動位於渦旋內核區時幾乎沒有螺旋臂結構形態出現，表明，初始擾動離tc中心越遠，其強迫渦旋rossby波形成的螺旋帶結構越明顯，反之越弱。The imf is of the view that, in the absence of any policy change or reform, the levels of reserves needed to anticipate fluctuations in revenue could be around 30 to 50 per cent of gdp, while those aimed at anticipating fiscal pressures arising from population ageing could mean putting in an additional 30 per cent of gdp by 2030
基金組織認為，假如沒有任何政策轉變或改革，香港的理想儲備水平應該維持在相等於本地生產總值百分之三十至五十，以應付收入波動而在二三年則額外需要相等於本地生產總值百分之三十的儲備，以應付人口老化所帶來的財政壓力。The aerodynamics characteristic of spinning projectile with lateral jets has constitutionally difference in formation from that without jet, and it waves periodically. these characteristics are very important for the study of aerodynamics of projectile with lateral jets
與光彈體相比，旋轉側噴彈丸的空氣動力特性不僅在形成機理上發生了本質變化，而且在數值上表現出復雜的波動形式，這些特點將對旋轉側噴彈丸空氣動力研究帶來直接和深遠的影響。The smaller convective patch corresponds to slight changes of maximum mean wind speed and the larger convective patch corresponds to the waves amplifying, the intensity of the inward propagation of vorticity strengthening distinctly, the amplitude of velocity change increasing and the period longing
初始擾動尺度減小，渦旋rossby波減弱，對tc強度增強作用減弱；擾動尺度增大，波動增強，向內傳播的渦量顯著增大，但轉化為渦量帶現象變化不大，風速變化的震蕩性增強。分享友人
