A theory of aeroelastic stability of hingeless rotor blade in hover by using the Galerkin weighted residual finite element method is developed in this paper.

采用伽辽金加权余数有限元素法发展了一种悬停状态下无铰旋翼桨叶气弹稳定性的分析方法。

A device,such as a looped rope,hook and eye,strap,or grommet,used to hold or f as ten loose ropes,spars,or oars in position.

环索一种类似于绳圈、钩子和线圈、皮带或金属索眼的装置，用于把松了的绳索、桅杆或桨保持或紧固在其位置上

A device,such as a looped rope,hook and eye,strap,or grommet,used to hold or fasten loose ropes,spars,or oars in position.

This means that if the kayak capsizes it will not fill with water and the paddler can, with a manoeuvre known as an "Eskimo roll", right the boat again.

这就意味着如果皮艇翻了，它也不会进水，而桨手可以用一种叫做&爱斯基摩翻滚&的动作，再把船给正过来。

For a kind of nonlinear dynamic absorber of blade out of plane, the combination resonance is studied in Chapter 6 by using the method of multiple scales. The approximate steady state solution of the first order is derived first Then, the stability and bifurcation properties of the system response are investigated.

我们针对一种桨叶挥舞方向的非线性动力吸振摆，利用多尺度法考察了它发生组合共振的情形，给出了系统响应的一阶近似稳态解，并且详细分析了系统响应的稳定性和分叉特性。

Today's killer drone is a slow-flying, easy-to-spot turboprop plane that drops relatively-crude munitions on its targets.

当今的攻击型无人驾驶机是一种飞得慢、容易被发现的涡轮螺桨推进飞机，向目标投弹精度也相对较低。

TXT_KEY_EVENT_TRIGGER_REINFORCED_HULL_1 Our shipmasters have devised a way to reinforce the hulls of our triremes.

我们的船长们创造出一种方法来加固三层桨战船的船身。

In spring, father dug edible wild herbs for us; on the Dragon Boat Festival, father sent us palm-leaf rice dumplings; in autumn, father carried the self-planted vegetables and fresh corns on his bike and rode for thirty kilometers and took them to us. Knowing that we were busy, he sometimes didn't even have a drink before leaving.

春天父亲给我们挖苦菜，端午给我们送粽子，秋天把他种的瓜果蔬菜和刚上了桨的玉米，骑上自行车往返三十多公里送到城里，知道我们忙，有时连水也不喝一口放下就走。

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%.
