自由浮時 的英文怎麼說
中文拼音 [zìyóufúshí]
自由浮時
英文
free slack-
The instability in the natural convection boundary layer initiates with the buoyancy eigenmode and develops into non - linear stage with the turbulization of the buoyancy eigenmode. in the mean time, the invisid eigenmode at the inflexion point appears and begins to increase at the outer layer. experimental results show that the turbulent layer near the maximum velocity point can be detected while the reformed grashof number
自然對流邊界層的穩定性由浮力振型失穩開始，並隨著浮力振型的湍流化進入非線性階段，與此同時，無粘性振型在外層開始失穩。實驗結果表明，修正格拉斯霍夫數grashofA two - dimensional double diffusive laminar natural convection in rectangular enclosure is detailed analyzed. the results show that when the thermal and solutal buoyancies aid each other, the airflow consists of one main cellular structure and is steady, regardless of the relative strength variation between the heat and pollutant sources. there are multiple flow structures, however, according to the relative strength when the buoyancies opposing each other
模擬結果表明雙擴散自然對流系統的空氣流動與傳熱傳質特性完全是由離散熱源與污染源浮升力之間的相互作用關系訣定的：當離散熱源與污染源浮升力協同作用時，自然對流呈比較穩定的單一流動結構；而當熱源與污染源浮升力對抗作用時，自然對流系統隨它們之間強度變化呈現出多種流動狀態。It s still very easy for me to be influence by others and go astray from my principles when i m in a crowd of people. my heart is not very solid yet. so repentance is to trim away some of your expectation, trim away some of your desires, and trim away bit by bit the things stored up in your heart
不過我知道，在修行還未到家之前，待在家裡確實是個比較安全的選擇，因為當我和一大堆人在一起時，的確很容易受到他人的影響，而失去自己的原則，我的心還不夠堅定，所以需要藉由懺悔，一點一滴將心裏浮華不實的慾望喜好除去。One side, groovy cast steel flap valves increase the head loss, waste electricity, the other side, when flap valves close, it always delay time because of it ' s low proportion. the bump load seriously threaten the safety of pumping station. through the research and development of flap valve used in the renovation practices in the design of air - filled floating flap valve in no. 1 chuhe pumping station of anhui province, the working characteristics and design methods of air - filled floating flap valve are studied in this paper
但在拍門運行使用的同時，又時常暴露出一些缺陷，主要有：一是常規的鑄鐵或鑄鋼拍門加大了流道的水頭損失，特別是對于裝機容量較大的排澇泵站，其電能損耗相當可觀；二是拍門在自重下下落關閉時，往往由於過多考慮水頭損失導致浮重過小而延誤閉門時間，致使水體倒灌，再因緩沖裝置失靈導致閉門時門體對門框撞擊力很大，嚴重危及站身安全。As well - known, there is an induced current on the surface when metal material is in the high frequency electromagnetic field, since tending to skin heating effect to make the temperature of metal material surface go up promptly, surface beginning melt when temperature reaches the melting point of metal, metal material is heated up continuously by surface to core till the metal droplet of melting
自懸浮定向流技術制備金屬納米微粒與一般的蒸發冷凝法有所不同，其原理是：金屬材料在高頻電磁場中產生表面感生電流，由於趨膚加熱效應使得金屬材料表面的溫度迅速升高，當溫度達到金屬的熔點時表面開始熔化，通過熱傳導作用金屬材料由表面到芯部不斷加熱直至熔化成金屬液滴。The national question in yugoslavia became acute during the period of sfry, the reason was that on the way of the reform of yugoslavia autonoraic socialism, federalism decentralized excessively, emphasized absolute equality of the nations, and this " confederalization " misplay of institutional leaded the national question in yugoslavia to coming out again
南斯拉夫聯邦時期民族問題從緩解到激化的消長歷程，其緣由並非在於南共對聯邦制這一國家結構的選擇，而是南斯拉夫在自治社會主義制度探索和改革中，其聯邦制發生了過度分權、強調民族絕對平等的「邦聯化」畸變，這種制度變遷上的失誤才是南斯拉夫民族問題重浮水面的主要原委。分享友人
