大圆弧

The double circular arc spiral bevel gearing is a type of points contact transmission by concave-convex tooth profile between meshing gearing, it has the advantages of large comprehension radius of curvature, good lubricating ability etc..

双圆弧弧齿锥齿轮传动是一种凸凹齿廓相接触的点啮合传动，有较大的综合曲率半径，因此有很高的接触强度；且润滑效果良好。

And it was suggested as well that assuming of the deformation curve could quite affect the damage evaluation result.

针对目前研究中应用深梁模型时弯曲变形曲线形式的假定进行了探讨，从理论和实测结果两方面说明圆弧假定是不合理的，同时也说明曲线形式的假定对破坏判断结果影响非常大。

According to the theory calculation results of elastic contact status of roller and rib of 91754EQ bearing, the conclusion is that the arc rib is more easy to establish this oil film than tapered surface rib, and so when selecting proper geometry dimensions of arc rib and the long axis of contact ellips...

通过对 9175 4EQ轴承滚子-挡边的弹性接触状态理论计算表明：与锥面挡边相比，圆弧挡边更容易建立这种润滑油膜，而且通过合适选择弧挡边几何形状尺寸使接触椭圆长轴重合于卷吸速度方向时，将能够得到更大膜厚比数值的润滑油膜

According to the basic equations derived under the two assumptions by Harold Lauffer—(1) the energy head of every point of a vertical section remains constant,(2) the flow lines are concentric circular arcs,this paper qives a comprehensive deduction of curvature effect in the characteristics of free overflow of round-crested spillway.118 runs of experiments of three round-crested spillway models of different size have been conducted by the author.

本文根据劳弗尔氏在两项假定[(1)垂直测线上各点所含能量为常数，(2)流线呈同心圆弧]下所导得的基本公式，作了详细的补充引伸，得出圆顶壩自由溢流时各项水力特性中的曲率影响计算公式。作者曾进行了大、中、小三个圆顶壩模型的试验共118组，试验成果基本上和导得的计算公式相合致。文中并根据试验资料制定了一些经验公式，应用时可更简便。

For example, multi-purpose cutting board, with volume below the water heater went door screens so that the electrical contractors have huge ingeniously hid; German-style pillars beside it called "style" could be stratified or some sporadic notes things; The small monster Lalan the corner, not only fresh names, and the maximum use of a corner, All metal parts are relevant world-renowned brand, comes from 10 to 150,000 times, that is 10 to 15 years there will be no problem; the most creative is an embedded hands-free phones and radios, and one can learn while chatting with the respondents, about time, being busy at the hands of food, but also can listen to the radio work, even cooking are also many warm, not to mention the taste of food; In order to prevent child injuries, all the glass jars are earthquakes, Zhuojiao is arc, holding a sleek strong lines.

例如多功能菜板，下面用卷帘门包起了热水器，让本来庞大笨重的电器巧妙地藏起来；旁边的德式吧台柱叫&顶天立地&，可以分层放一些零散顺手的东西；下面这个转角小怪物拉篮，不仅有新鲜的名字，而且最大限度的利用起角落，所有相关的金属配件都是世界知名品牌，能开10至15万次，也就是10至15年没问题；最有创意的是嵌入式免提电话和收音机，一人下厨时可以边与被访者聊天、约时间，边忙活手里的饭菜，还可以听着广播干活，就连下厨热情也高涨了许多，更不必说饭菜的味道了；为了防止小孩受伤，橱柜所有的玻璃都是防震的，桌角是圆弧的，拉手采用光滑的强流线型。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
