上坡

The first part of the ascent is not steep.

开始一段上路并不陡。

I dismounted and began to push my bicycle up the hill.

自行车来，开始推着上。

Such results are gotten: (1) Due to the unique topography the wind of Beijing area during the day time is southern anabatic wind and in the night is northern katabatic wind in summer.

(1)北京区域夏季边界层风受西北特殊地形的影响,夜间低层大气流常表现为由北向南的风,白天逐渐转为由南往北的上风。

Curve and uphill path resistance are great, linear resistance is little, declivous path still has quicken force.

曲线及上道阻力大,直线阻力,道还有加速力。
