Appends an elliptical arc to the current figure 向當(dāng)前圖形追加一段橢圓弧。
Taking practical situation of this project and much engineering experience into account , the scheme with axle golden section elliptical arc surface is proposed through comparing nine optimization schemes with model test 結(jié)合工程實(shí)際和以往經(jīng)驗(yàn),比較了9種進(jìn)水口曲線型式的試驗(yàn)結(jié)果,確定了長(zhǎng)短軸黃金分割比的橢圓弧面的方案。
