  1. An echoic studio

    短混響的
  2. Again we take an imported 500 kw engine unit as the example. in this case baffle boards are stuck on walls inside the engine room, meanwhile baffle boards are also used as suspended ceilings. by doing so not only the amount of insulated sound of the fender structure is increased, but the reverberant sound in the engine room is also depressed ( normally by 3 to 5db )

    我們仍以一臺500kw進口機組為例,油機房內墻面設計為貼板,同時用板吊頂,經過這樣的處理后既增加了圍護結構的隔量,又可降低油機房內的混響,一般可有3 ~ 5db ( a )的效果。
  3. Studio magnetic film transports for sound recording and reproduction ; specifications and requirements

    和放的磁帶輸送裝置.規范和要求
  4. A radio announcer ' s voice is his

    電臺員的就是他的飯票。
  5. For shutters, the results show : 1 ) according to the formula p =, the theoretical value of is calculated by the effective velocity of the flow, and its engineering value is calculated by the arriving velocity of the flow, the relationship between the theoretical value of and its engineering value is 2 ) the smaller value of declining angle will result in the smaller pressure loss and smaller outlet velocities. as a result, the declining angle of 30 擄 or less is recommended in some places which need small wind velocity, such as broadcasting studio and library, and the declining angle of 45 擄 or less is recommended in places which need big wind velocity, such as cinema and office ; 3 ) the larger value of ratio between the wide of the shutter b and the space between two boards h ( b / h ) will result in the larger pressure loss and smaller outlet velocities. the range of b / h from 0. 8 to 2. 0 and the optimum value 1. 2 is recommended ; 4 ) the range of b from 10 mm to 50 nun and the optimum value 40 mm is recommended ; 5 ) the proper thickness of the boards 8 of the shutters is 1. 5 mm ; 6 ) cuneiform boards should replace the rectangle inlet boards of the shutters in order to obtain better ventilation

    數值模擬採用fluent軟體,計算結果用excel進行處理,通過對大量數值工況進行數值模擬計算,結果表明:對于單側百葉風口,計算表明: 1 )對于公式p = ( ~ 2 ) 2 ,的理論計算值中定義為流體流經百葉風口內部時的速度,即有效速度,而工程上常使用流體的來流速度來計算,計算表明,的理論計算值與工程應用值的關系為( _ (理論) ) ( _ (工程) ) = 0 . 813 ; 2 )當來流速度一定時,擋板傾斜角度越小,壓力損失越小、出口速度越小;因此在要求進口風速比較小的場所,如、圖書館等,宜採用擋板角度30的百葉風口;在要求進口風速比較大的場所,如電影院、辦公等,百葉擋板的角度應選45 ; 3 )當來流速度一定時,百葉擋板的擋板寬度b與擋板間距h的比值b h越大,壓力損失越大,出口速度越小,計算表明,鑒于壓力損失、出口風速、板間形成渦流區的大小,百葉擋板的b h值取0 . 8到2 . 0之間, b h = 1 . 2為最佳值; 4 )當來流速度一定時,在計算的條件下,當百葉擋板寬度b = 40mm時,百葉擋板的阻力系數最小,考慮到渦流區等的影響,建議選用10mm b 50mm的百葉擋板;西安建築科技大學碩士學位論文5 )百葉擋板的厚度取為1 . sinln為好; 6 )百葉擋板的入口側可選用具有傾斜度的楔形擋板來代替矩形擋板,利用其較好的導流作用,可得到更好的出流效果。
