尖削

In this paper, the existing studies on new blade tips are divided into three phases. First, the conventional rectangular tip is modified into the simple straight swept or tapered tip or combined sweep and taper configuration.

本文首先将桨尖形状的研究区分为三个层次：第一层次是从矩形桨尖到简单直线后掠或尖削或后掠尖削组合的变化；

When we measure the kurtosis of a distribution, we are measuring its peakedness.

度量一条频率分布曲线的尖削度就是度量其顶部的峰态。

Green-pruning could also effectively control the length of knots on wood, reduce tree taper, improve the proportion of clear wood and the under branch height, so that to improve the stem form and quality.

人工修枝还能有效地控制木材中节子的长度，提高杉木无节材比例，同时减小尖削度，提高枝下高，使杉木干形更趋近于通直圆满。

The influence of sweep angle and taper ratio on the characteristics of wingtip stalling is discussed.

讨论了后掠角和尖削比这两个机翼外形参数对翼尖失速特性的影响。

The nose makes him looks like European. Thin lips Small chin Small face.

高挺、像欧洲人的鼻子. 薄唇.尖削的下巴和小脸.

Based on the wake model and the second-order lifting line theory, a new analytical method is emphatically developed to predict the aerodynamic behavior of the advanced rotor with a swept, tapered or swept-tapered tip shape.

将该方法和桨叶二阶升力线模型结合，建立了一个新的适用于后掠、尖削及其组合形状的旋翼气动特性计算的分析模型。
