The first part of the ascent is not steep.

开始一段上坡路并不陡峭。

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

我从自行车下来，开始推着上坡。

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

曲线及上坡道阻,线阻小,下坡道还有加速。

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)北京区域夏季界层风场受西北特殊地形的影响,夜间低层场常表现为由北向南的下坡风,白天逐渐转为由南往北的上坡风。
