滑翔

Today, the sport is divided into two disciplines: classic skiing which uses a straight-ahead gliding motion, and ski skating which makes use of glide and edge movements similar to ice skating or roller blading.

今天，这项运动分为两个学科：古典滑雪也是利用勇往直前的滑翔运动，滑冰和滑雪这使得利用滑行和边缘运动相似溜冰或滑旱冰。

Before flying , glider and sailplane pilots may be interested to know if there is adequate lift due to upward air currents

在飞行之前，滑翔机师及模型机操作专家可能想知道有没有上升气流提供足够的抬升动力。

Aviation sports activities , including paragliding and model sailplane soaring , are becoming more popular in hong kong in recent years

飞行运动如滑翔降伞和模型滑翔机近年在香港逐渐流行。

Therefore, the lift ratios, proportional to that square of speed as we know, are respectively 4 for a paraglider, 2.25 for a hang-glider and only 1.7 for a sailplane.

在如上的例子中，左右翼尖的的速度差别对于滑翔伞是2，对悬挂滑翔机是1.5，对于固定翼是1.3。

To give you a simple idea, one can say for instance that a paraglider usually turns with a radius of 2 wingspans, where a hang-glider and sailplane turn respectively with a radius of 3 and 4 wingspan The speed ratio between the left and right wingtip is from the above example; 2 for a paraglider but only 1.5 for a hang-glider and 1.3 for a sailplane.

为了比较简单的说明，这里以实例进行说明：滑翔伞以2倍翼展的半径稳定盘旋，而悬挂滑翔机和固定翼滑翔机以3，4倍翼展进行稳定盘旋。

Silhouetted against the sun, sandhill cranes glide over the wetlands of Bosque del Apache National Wildlife Refuge in New Mexico.

Americans enjoy many kinds of sports, such as bowling, skating, skiing, swimming, diving, skin diving, scuba diving, surfing, bicycling, car racing, drag racing, running, hang gliding, hocke, golf, and tennis.

美国人喜欢各种各样的运动，比如保龄球、溜冰、滑雪、游泳、跳水、潜水、戴水肺的潜水、冲浪、骑自行车、汽车竞赛、（在短距离直线跑道上举行的）汽车加速赛、赛跑、悬挂式滑翔运动、冰球、高尔夫球和网球等。

This is also a glide, a slinging, a rotation and relocation along with precise orbit.

这也是一次滑翔、抛射、旋转、迁徙，沿着自由而精确的轨道运行。

A few have managed to stay at sea for several months. In 2004 a sea glider built by the Scripps Institution of Oceanography in San Diego (and called Spray after Slocum's self-steering sailing ship) even managed to cross the strong currents in the Gulf Stream on a voyage to Bermuda.

很少有人能够成功在海上待上几个月。2004年由在圣地亚哥斯克里普斯海洋学研究所制造的海洋滑翔器（取名自斯洛克姆的自动转向帆船的"喷沫"）甚至在百慕大群岛的航行中成功的穿越了强大的墨西哥暖流。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
