尾流效應 的英文怎麼說
中文拼音 [wěiliúxiàoyīng]
尾流效應
英文
wake effect-
Then, this paper introduce a new method of measuring the risk ? ? cohesive value at risk ( cvar ), which is more logical than the var on optimizing the portfolio according to the characteristic of the stock bargaining market of our country, it constructs a corresponding index of liquidity risk of the stock assert of the open - end fund, and by constructing a optimized model in cvar, the liquidity risk of stock assert of the open - end fund is efficiently controlled
接著，本文引入了一種全新測量風險的方法cvar方法，並且根據我國交易市場的特點構造了相應的開放式基金股票組合的流動性風險指標，通過構造cvar調整的投資組合風險優化模型有效的控制了股票資產組合的流動性風險。本文的研究表明: （ 1 ）開放式基金股票組合的流動性風險具有明顯的尾部風險。Sound is a multidimensional medium, the fundamental dimensions of sound are pitch, timbre, loudness, duration and direction, further more, sound has multiple effects, these effects roughly are cocktail party effect, streaming, echo and reverb
聲音是一種多維度媒體，主要有音調、音色、響度、持續時間和方向等維度特徵；聲音又是一種多效應媒體，主要有雞尾酒會效應、流效應和回聲、反射等效應特徵。Flow details of measurement indicate that the coupling of periodic separated flow ( such as low frequency swinging of separation line ) with nozzle flow may cause aft - end internal flow unsteady. recirculation flow gains more energy from the main flow, at the same time the turbulence intensity increases
通過對測量結果的分析，我們認為分離流動的周期性（如分離線的低頻擺動）與噴管流動相耦合，會造成燃燒室尾部流動的非穩態效應增強，增加了迴流區從主流中獲得的能量，也加劇了流場的湍流脈動。Turbulent bl structure : wake, wall layers. inner, outer variables. effects of roughness
