Weather fronts are bound up with a frontal cyclone. 天氣的鋒面和鋒面氣旋密切相關(guān)。
The wetting front moved nearly parallel to the soil surface, and its length could be described by a power function of time, when the distribution of initial soil water was uniform. 當初始含水量分布均勻時(shí)，降雨入滲過(guò)程中濕潤鋒面幾乎平行坡面運移，濕潤鋒深度與時(shí)間的關(guān)系可用冪函數描述。
Soft frontal lighting smooths over form. 軟正面照明平滑的形式。
The enemy made a frontal attack on our troops. 敵人對我們的部隊發(fā)動(dòng)了一次正面的進(jìn)攻。
