To take away this discouragement , I resolved to dig into the surface of the earth , and so make a declivity .
为了扫除这个障碍,我决定把地面掘平,掘成一个向下斜的土坡。
If the line slants downward , it is descending , or is said to have declivity , and the slope will be a negative number .
如果这条线向下倾斜,它是下降的,或者说是下坡,那么斜率是一个负数.
It seemed to him that he had but just waked up from some inexplicable dream , and that he found himself slipping down a declivity in the middle of the night , erect , shivering , holding back all in vain , on the very brink of the abyss .
In that fatal valley , at the foot of that declivity which the cuirassiers had ascended , now inundated by the masses of the english , under the converging fires of the victorious hostile cavalry , under a frightful density of projectiles , this square fought on .
