重摺率 的英文怎麼說
中文拼音 [zhòngzhélǜ]
重摺率
英文
birefringence-
In spinning process, what should be done is to improve the coherence force of the fibers due to the linen fiber being thick, stiff, smooth, super long and containing more short fibers, causing difficulty to spinning ; in weaving it should focus on the settlement of unclear shedding and more ends breaking caused by fuzzy & poor elasticity of the warp yarn ; finishing plays an key role in improving fabric appearance to solve fold mark & frost mark and enhance style of peach skin and linen knot effects
紡部工序主要克服天絲與亞麻纖維抱合力低，特別是亞麻纖維粗、硬、滑、超長纖維和短纖維率高給紡紗工藝帶來的困難；織造工序重點解決成紗毛羽對開口清晰和經紗彈性差對斷頭的影響；后整理涉及影響外觀質量的摺痕與霜印問題，並要突出桃皮絨和獨特的亞麻麻節外觀效應。The flows in the case of different reduced frequencies are computed respectively for two blade profiles. by comparing the time curves of relative parameters in oscillating cascades and the flow field contours under different conditions, it is indicated that the reduced frequency is an important factor to determine whether the blade flutter happens or not
針對兩種葉型分別計算了不同摺合頻率下的流場，通過比較振動葉柵相關參數隨時間變化的曲線及流場雲圖，表明摺合頻率是決定葉片顫振與否的重要因素。
