The fifth chapter sum up the article and view the work . the simulation results indicate : ( 1 ) exchanging of sea - air and force of dynamical and thermodynamic processes is very important to bring and maintain sea surface wind . shf is mostly energy sources and lhf is negative effect in some area 模擬結果充分表明: ( 1 )感熱和潛熱的海氣交換和動量交換(摩擦作用)對于海面風的發展和維持起著重要作用,潛熱加熱是海面風中最主要的能源,感熱通量在一武漢理工大學碩士學位論文定區域對海面風風場有負面影響。

When shfs level two was activated , the acting chief executive , mr donald tsang , convened the level two steering committee to formulate and direct an overall disease control strategy and decide what other measures should be taken , including decisions that have a wider impact on the community 當戒備級別第二級生效后,署理行政長官曾蔭權召開第二級應變工作督導委員會,制訂整體疾病控制策略,并決定采取何種措施,包括那些對社會有廣泛影響的決定。

Magnetron management of target capacity and stabilization of an anodi current with the help of the built - in electromagnet , an opportunity of a parallel feed several magnetrons from one rectifier , a low level of the shf radiation from a cathodic leg is characterized effective 該磁控管可有效控制輸出功率,內建電磁石使提高了它的陽極穩定性,一個整流器可同時供幾個磁控管,具有低的陰極超高頻輻射。

( 2 ) increasing of wind is mainly induced by shf and affecting of lhf is very little . ( 3 ) effect of terrain increases ground rough and tonsure of terrain press and fiction correspond enhance frictional damp effect ( 3 )地形作用相當于增加了地面粗糙度,地形壓力梯度項與摩擦項地疊加,相當于使摩擦阻尼作用增大,地形強迫作用使下邊界層從上至下風速減小,風向向左偏轉。

Shf communication technologies ag deals among other things in test equipments , variable - speed propulsions as well as in amplifiers , wide band , top hat rails and also in connectors Shf communication technologies ag是一家可靠的、知名的生產商和服務商,該公司提供很多令人震驚的產品,例如試驗器材,調整傳動裝置。

The exercise came to the end with a mock evacuation of residents from a building affected by shfs . end friday , november 19 , 2004 演習的最后部份是模擬調派前線人員,協助一座受shfs影響大廈的住客撤離居所。

Magnetron it is characterized by small weight and a low level of the shf radiation from a cathodic leg 其特點在于小的重量和低的陰極超高頻輻射。
