This decline is soon reflected in the yield of crops. 這種下降馬上反映到作物產量上。
"A sweet temper" is a figurative expression, but "sweet coffee" is not. "甜蜜的性情"是個比喻的說法,而"甜咖啡"則不是。
Farmers can lose rather than gain if incomes fluctuate because of variations in crop yields and outputs-stable prices can then destabilize incomes. 農作物產量和產值的變化如果引致收入波動,這對農民來說就可能是有害無益,因為穩定了價格可能穩定不了收入。
This paper discusses the construction and the computation of quotient space, and the application for yield forecast.Finally, the experimental result is satisfied. 該文主要描述了商空間粒度的構建和計算並應用於農作物產量的預測,通過實驗取得了很好的確定結果。
