地面高度

As with many businesses during those days, their company grew rapidly and they established the first successful regular service between Wilmington and Avalon with a Curtis "Seagull" flying boat.

北方军的优势很快胜于联军，因为他们能用绳索将一些氢气球快速升至几百英尺的高度，从而发现联军，然后把莫斯代码信息发送给地面控制气球的人。

Contributions of the Shanxi sources to the PM10 concentrations over Beijing are up to 10～30μg/m3 in the surface layer while up to 30～70μg/m3 at a height of 500m.

山西排放的PM10对北京地区近地面PM10浓度的影响可达10～30μg/m3，500m高度的影响高达30～70μg/m3。

These planes fly at about 300 feet above the ground, gaining speed to avoid getting shot down.

这些飞机的飞行高度距离地面300英尺，它们提速飞行以免被击落。

Ground Control:" State your height and position."

地面控制："速报高度与位置。"

If you think of the swing volley as a high ground stroke, it's easy to learn: prepare early with your ground-stroke grip and with the racquet at the height of the ball, hit the ball at its peak, and drive it.

如果您认为回旋球作为一个高射炮，学会是容易的：及早准备与您的地面冲程握把和用球拍触球的高度，击中球在它的最高点的时候，并且驾驭它。

Strong commercial construction has created a ground swell of demand for small rough-terrain scissor lifts that can put tradesmen within reach of three- and four-story work. Contractors need scissor lifts that perform like RT booms on the site before there is a concrete slab or power to recharge batteries to keep pace with building development.

坚固的商业建筑使得可将作业人员升举到三四层高度的小型不平地面剪式升降机的需求越来越大，承包商需要与RT起重臂性能相类似的剪式升降机，然后出现混凝土板以及可对电池进行重新充电的动力源，以此来保持与建筑发展齐头并进。

Raise the tackle above ground for about 500mm using man power, until it goes to OA, start elevator; pull the tackle with low speed to OB (inclination angle=45 degree), and then use man power to lift the front legs slowly, put them into the two holes in the beam.

用人力将滑车抬起离地面约500mm高度达到OA位置，启动升降机；低速缓慢拉起滑车部位及至OB位置（倾角45度）时，再用人力将前支腿缓慢撑起，置于横梁两端的孔中，前后支腿用侧连杆连接好。

The slope can be adjusted to be in same level as ground to facilitate pass-in and out of handcart, fork, or construction material

可以调节坡度，使之与地面一样的高度，方便手推车，叉车等机械或者建筑物料的进出

This service offers an hour-long wedding in outer space about 100 km above the earth's surface.

在一小时的飞行过程中，两位新人将到达距离地面100公里的高度。

For comparison, Iridium fragments are confined to altitudes between 582 km and 1,262 km.

相比之下，铱33卫星碎片则分布在距地面582公里至1262公里的高度之间。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
