比尤雷高
英文
bjuregard-
( 2 ) on the leading edge, the film cooling effectiveness at the zone immediately downstream of the cooling holes is affected by blowing ratio and mainstream reynolds number, while the effects are not important in the downstream zone far from the cooling holes. ( 3 ) on the front half of pressure surface, the effectiveness increases with decreasing blowing ratio at the downstream near the cooling row and it is contrary at the downstream far from the cooling row. ( 4 ) on the rear pare of the pressure surface, the effectiveness decreases with increasing blowing ratio and does not vary so much downstream in the cases of higher blowing ratio
研究結果表明葉片吸力面端壁附近區域壓力系數分佈呈現出較強的三維特性，動葉吸力面尤其明顯；氣膜孔流量系數隨吹風比的增加而增大，在高吹風比情況下，流量系數逐漸趨于常數；在不同型面區域，冷卻效率分佈有較大的差異，而且吹風比與主流雷諾數的影響程度也不盡相同；低吹風比下，孔出口下游附近可以得到較好的冷卻，中、高吹風比下，冷氣射流在加速流動主流的作用下返回壁面進行二次冷卻，孔下游較遠區域可以得到較好的冷氣覆蓋。Frequency source is widely used in today ' s electronic equipment and even refered as " a heart " of many electronic systems. the frequency synthesizer with a lot of channels and high frequency stability by means of theory of phase locking has almost been a necessary component in the modern electronic systems such as telecommunication, radar and electronic countermeasure. the phase - locked frequency synthesizer can be generally divided into two kinds : one is digital phase locked frequency synthesizer, the other is analog sampling phase locked frequency synthesizer. compared with the prior, the latter has many merits such as lower phase noise, samller volume, lighter weight and lower power consumption and has a wide foreground in the equipments of microwave band
利用鎖相原理來獲得波道數目眾多、頻率穩定度很高的頻率合成器，幾乎已成為現代通信、雷達和電子對抗等電子系統不可缺少的組成部分。鎖相式頻率合成器一般分為數字鎖相頻率合成器和模擬取樣鎖相頻率合成器兩類。取樣鎖相頻率合成器與數字鎖相頻率合成器相比，具有相位噪聲低、體積小、重量輕和功耗低等優點，尤其在微波波段的電子設備中，具有廣闊的應用前景。Thunderbolt four not only inherited the previous version download quickly, further optimization software architecture itself achieved a downloadable " fast and stable " by downloading resources to achieve the optimal integration of downloadable " fast and the whole " more user document management to provide a relatively complete support, particularly for users of concern to the configuration, proxy servers, document management category, volume downloads for the expanded and improved, making thunderbolt meet, advanced users download the most professional requirements
