The fresh water of the Pearl River has a lesser influence than in summer and water salinity is more uniform across Hong Kong. 珠江的淡水此時(shí)造成的影響較夏季時(shí)為小，使本港各地的水質(zhì)咸度較為一致。
Normally, in tropical regions where the sun is very strong, the ocean salinity is higher than it is in other parts of the world where there is not as much evaporation. 通常熱帶地區陽(yáng)光強烈，而其他地區海水蒸發(fā)量不如熱帶地區那么大，因此這些地區海水咸度要高些。
Salinity refers to the total concentration of salts present in the soil solution. 含鹽量是指土壤溶液中所存在的鹽類(lèi)的總濃度。
The subject is beyond the scope of this section inasmuch as it depends to a large extent on the dynamics of salinity intrusion. 這個(gè)問(wèn)題已超出了本節的范圍，因為這個(gè)問(wèn)題在很大程度上取決于含鹽量入侵的動(dòng)力學(xué)。
