钝头的

Hornless head, there is a pair of blunt incisors, lower molar crown, was a simple π-shaped.

头上无角，有一对钝的门齿，臼齿低冠，呈简单的π形。

Based on this analysis, a new method for evaluating the bluntness magnitude of a Berkovich indenter was proposed. This method was examined by the experimental results of indention loading curves for pure nickel and aluminum alloy 8009, and good agreement was obtained. For thin metal films deposited on hard substrate, a method is established for determining the yield strength and hardening index of the film from nanoindentation loading curve.

通过对理想与钝化Berkovich压头以及球形压头纳米压入软膜/硬基材料加载过程的数值研究，给出了两种压头纳米压入加载曲线的幂函数拟合指数及最大压入载荷同膜、基材料基本力学性能间的函数关系，并分别就Berkovich压头与球形压头建立了由纳米压入加载曲线确定沉积在陶瓷基体上金属薄膜屈服强度与硬化指数的方法。

While the experimental side force distribution over a slender body with a blunt ogive nose is basically consistent with the curve of the analogy predicted, and the characteristic points and half cycle of the experimental curve are basically constant with the roll angle changing 360°. But the local maximums in the curve are not the results as the analogy predicted, which is an important flow feature of 3-D slender body than that of 2-D cylinder.

而钝头拱形细长体在大迎角下的截面侧向力分布与脉冲起动横流比拟方法预测的侧向力曲线的形状是基本相同的，而且随着滚转角旋转360°，截面侧向力分布曲线的特征点和半周期基本保持不变，即它们都基本上不受滚转角变化的影响；但是截面侧向力分布曲线极值点形成的原因却是不同的，这是细长体绕流区别于二维圆柱绕流的一个重要特性。

Overview: Qinghai Lake Huangshui body exposed fish without scales, and only remnants of hip scales, body extended, flat side, 60 centimeters long and weighed 10 kg, such as spinning whip-shaped head and a blunt and round, no beard, back taupe , abdomen white, the body irregular spots on both sides.

概况：青海湖湟鱼全身裸露无鳞，只有臀鳞残存，体延长、侧扁，长达60厘米，重达10斤，形如纺棰，头钝且圆，没有胡须，背部灰褐色，腹部白色，身体两侧有不规则的斑点。

Cystoliths dotlike or very short blunt rods; stigma often on a style, mostly linear, less often penicillate-capitate; perianth lobes of female flowers usually connate into a tube, rarely strongly reduced, or absent, staminodes absent.

乳状体圆点状或者非常短钝的杆；柱头通常在花柱上，多数线形，较少经常具毛撮头状；通常的雌花的花被裂片合生成筒，很少强烈降低，或无，退化雄蕊缺席。

Style persistent; stigma capitate. Capsule subglobose, slightly laterally compressed, apex rounded-obtuse and emarginate, loculicidal.

花柱宿存柱头头状蒴果近球形，稍侧面压扁，先端圆形的钝的和微缺，室背开裂。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
