backfilling

基本解釋

In some cases, they're cutting more staff than their operating plans require, and backfilling with what they hope will be more qualified, and thus more profitable, employees.
很多情況下，他們裁員人數過多以致滿足不了當前的公司運作要求，然后又重新招聘他們期望更符合條件的員工來填補這些空缺，因此求職者就有更多機會了。
Its capacity of resisting large external load enables it not to rely on lateral support of the soil, therefore its requirements on backfilling soil is lower than on flexible tubes.
由于它本身能抵抗較大的外荷載，使其不須依賴土壤的側向支撐，因而對回填土要求較柔性管低。
