Thus, by gradual development, the rotor jets (which had a high fuel consumption) were only used for take-off, hovering and landing, and the rotor blades turned by autorotation for forward flight in the manner of an autogyro.

因此，通过逐步发展，转子飞机仅用于起飞，悬停和着陆，并为着在地的旋翼飞行自动旋转转动转子叶片。

Behind him his bassists and keyboarders joined into the driving hard-blues inspired jackhammer beat in synchronous turns, and when Key bounced up behind the drums, the music shifted and the crowd roared.

在他后面他的低音乐器演奏者和 keyboarders 努力地进入那驾驶之内参加-蓝调激发，手提钻在同时的旋转中打，而且当钥匙在鼓后面跳上的时候，音乐改变而且群众吼。

Its wheels are now buried about halfway in the soil, which is so loose "it's like flour", says Callas. Mission managers have temporarily stopped trying to drive the rover as they consider how best to proceed.

在最近的一次操作尝试中，&勇气&号上五个仍可以旋转的轮子深深地陷入了火星土里，目前大约已经有半个轮子陷入地下。

Since then, sounds of doors slamming and bands playing had been heard there. Swarms of flies infested the place. Green slime oozed from the hall walls, crucifixes rotated and a child with red glowing eyes was seen at the top of the stairs.

从此便有人在那房子里不时听到大门砰地关上，乐团霍地奏响；成群苍蝇遍布，大厅墙壁渗出绿色黏液，还看到旋转的十字架和楼梯顶端的小孩双眼血红，幽光冥冥。

By processing dechirped raw data, the algorithm uses the squint mode coordinate and line-of-sight polar interpolation to make full use of the data in space demain.

该PFA算法采用斜视坐标旋转及沿视线方向的极坐标插值LOSPI，更好地利用空间域数据，适用于正侧视和斜视模式成像。

Whirling in ecstacy, dervishes of the Mevlevi Order in Istanbul perform a ritual dance each December to commemorate the death in 1273 of their founder, Celaleddin Rumí.

伊斯坦布尔梅夫拉那教团的伊斯兰教托钵僧正在狂喜地旋转，为了纪念于1273年逝去的教团创建人杰拉鲁丁鲁米，他们每年的12月都会进行这个宗教舞蹈。

After a while the fish stopped beating at the wire and started circling slowly again.

过了一 会以后，鱼停止攻击钓钩上的金属线，又开始慢慢地旋转。

Salisbury, United Kingdom, February 24, 2009--Robes and flapjacks flying, choristers-in-training flip out on the Christian holiday Shrove Tuesday—aka Pancake Day in Britain—the last hurrah before the sober season of Lent.

2009年2月24日，英国，索尔兹伯里---长袍与甜燕麦饼在空中飞舞，受过良好训练的唱诗班成员们在基督教节日忏悔星期二---在英国又叫薄饼日---上发疯地旋转，这是在冷清的四旬斋前最后一次的狂欢。

When the lock ring simultaneously with the question cone gear engagement ring gear, cone after contact friction moment in the role of the rapid speed of gear to reduce to synchronize with the speed equivalent to lock ring, the two synchronous rotation, relative to gear Central lock synchronization speed is zero, thus inertia torque also disappeared, then in force under the impetus of engagement sets unhindered and synchronization lock Gear engagement ring, and further engagement with the question of gear engagement ring gear and completed Shift process The topics mainly through the Pro / E synchronization software for the car to three-dimensional modeling structural design, and through the parameters of the design process to achieve its structure, and on this basis, the use of ANSYS FEM software structure of the typical synchronization And a finite element analysis, through structural analysis of its structural design is reasonable to assess and make recommendations to improve the design

当同步锁环内锥面与待接合齿轮齿圈外锥面接触后，在摩擦力矩的作用下齿轮转速迅速降低到与同步锁环转速相等，两者同步旋转，齿轮相对于同步锁环的转速为零，因而惯性力矩也同时消失，这时在作用力的推动下，接合套不受阻碍地与同步锁环齿圈接合，并进一步与待接合齿轮的齿圈接合而完成换档过程本课题主要是通过Pro/E软件对汽车同步器进行三维造型结构设计，并通过参数化实现其结构设计程序化，在此基础上，利用ANSYS有限元软件对典型同步器结构进行有限元计算与分析，通过结构分析对其结构设计的合理性作出评价并提出改进设计建议

However hard you may rub a grain of gold against a grindstone, still a bit of it always remains.

无论你多么努力地用旋转磨石去磨一颗金色的谷粒，总是会有少许的金留在上面。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
