临近空间是指距离地面20-100公里的空域，不在传统航空和航天的覆盖范畴内，是人类尚未进行大规模利用的空白区域。 临近空间不仅从空间层面连接着天空和太空，同时也将航空与航天的技术进行深度融合。临近空间飞行器（临空器）是指 能在临近空间空域内飞行并执行特定任务的飞行器。从广义上讲，我们将临近空间内飞行速度超过1.2马赫的各类飞行器 统称为超音速临近空间飞行器。

目前，火箭推力与运载能力决定人类可以携带多少设备和资源进入太空，所以在发射频率提高之外，火箭能力的提升也是全球航天发力的关键要素。中国长征五号之后的“新火箭”，在起飞推力方面和过去有明显的提升，这也是中国航天产业未来想象空间的先决条件。中国的天宫空间站核心舱重量22吨，所以从全球现役火箭运载能力上看，能够负担近地轨道20吨以上重量这种任务的火箭只有六型。而这六型火箭在执行地球同步轨道以及更艰巨的深空探测任务时，可负担的载荷重量也非常有限，所以从全球视角来看，人类飞出地球摇篮的能力依然较弱。值得安慰的是，中国长征五号的运载能力已经达到国际顶尖水平，这也使我们在太空探索领域有了新的话语权。

8 月航司供需受南京疫情冲击：8 月三大航合计RPK 同比-53.2%（7 月为+31.6%），合计ASK 同比-41.1%（7 月为+26.6%）；对比2019 年， 8 月三大航RPK-74.6%（7 月为-36.9%），ASK-62.7%（7 月为-31.1%）。 南京疫情传播链较长，延伸至扬州、张家界等地区，影响范围不仅局 限于江苏地区，例如8 月上海机场、深圳机场旅客吞吐量分别同比下 降61.9%、44.7%，航司经营受疫情冲击明显。

An e-bicycle or electric bicycle is a standard bicycle, which is equipped with an electric motor, a battery, and a drivetrain. The bicycle can be moved through pedaling or can run on rechargeable batteries. E-bicycles is simple to operate, convenient for all age groups, and serves as an environment-friendly means of transportation, in comparison to motored vehicles. In recent years, electric bicycles are being considered as viable transportation option due to their power capacity, long distance range, and moderate speed. The popularity of these bicycles is increasing, due to rapid urbanization and surge in vehicular traffic on streets.

A three-wheeler is a three-wheeled vehicle propelled by petrol/CNG, diesel, or electric motor. Three-wheelers are generally used as a commercial vehicle to transport passenger and goods. Three-wheeler mobility depends on the maneuverability, affordability, and door-to-door transport. As many developing countries specially in Asia-Pacific and LAMEA require faster and significantly cheaper option for public and goods transport, threewheeler suites the requirement best.
