curved tip 中文意思是什麼
-
Aggregate fruit spicate, 10 cm long, stipe 2 cm long ; follicles ellipsoid or ovoid, 1. 2 - 1. 5 cm long, apex with short and curved tip, outside inconspicuously sparsely lenticeled
聚合果穗狀，長約10厘米，柄長約2厘米； ? ?長圓形或卵形，長1 . 2 - 1 . 5厘米，頂端具短而彎的尖頭，表面具不顯著的稀疏皮孔。 -
In order to have a patent functional ostia, dissection within the duct itself should be kept as minimal as possible. the frontal ostia should be probed gently with a curved, olive tip suction, and the direction of the ostia should be ascertained. continued post - operative patency is usually assured when one can easily introduce an olive
為了獲得一個不閉塞的功能性竇口，應盡可能減少額竇開口導管的切除，用一個彎橄欖頭的吸引器探入額竇開口並注意開口的方向，開口內能容納一個吸引器頭的空間一般可以保證手術后竇口的通暢。 -
Abstract : this paper uses the topology theory to analyze the surface flow spectrums of straight, positively curved and negatively curved cascades with relative tip clearances of 0. 023 and 0. 036, finds apparent differences of topology and vortex structures in the blade tip and the suction side wall corner of single type of cascade with this two clearances, and studies the mechanism of the difference formation as well as their effects on the energy loss
文摘:應用拓撲原理分析了葉頂相對間隙為0 . 023和0 . 036的渦輪直葉柵和正、反彎葉柵的壁面流譜，發現在兩種間隙下同類葉柵的拓撲與旋渦結構在葉頂和吸力面壁角明顯不同，探討了差別形成的機理及其對能量損失的影響 -
The thesis studied the change of stress triaxiality in the four - point curved beam made in 16mnr with arc - tip crack and its important effect. in the beam, the points of peak value of stress triaxiality distribute along a line, whose direction is well consistent with the fracture direction got by experiment when so > 3mm
在圓弧裂紋試件中，裂尖附近的三軸度較高的點呈脊線分佈，按照脊線分佈擬合計算得到的三軸度脊線夾角在偏心距so 3mm時與試驗測得的斷裂角符合較好，這種情況下試件發生的是韌窩型斷裂。
