  1. The addition of surfactant to etchant can protect surface from intense dissolution, and keep a relative similarity of dissolving activity between surface and tunnel walls. in order to gain a satisfactory enlargement of tunnels, the etchant temperature should be controlled at 70 - 90

    3a / cm ,嚴重,使比容降低;溶液中添加表面活性劑可以有效地抑製表面溶解,提高比容;適宜的擴孔條件為:溫度80oc ; h +濃度lmol / l0
  2. The new technology of non - contact life - parameter detection is relative to that of the normal contact one, which uses microwave beams to illuminate the human subject, whose reflected wave will be modulated by the surface movement resulting from the physical activity. by this way, some parameters of the reflected wave, such as frequency and phase will be changed. if these changes can be detected, the life parameters such as respiration rate and heartbeat rate will be extracted from those changes

    非接觸生命參數檢測是相對于常規的接觸式檢測而言的一種新技術,它利用微波束照射人體,其回波信號被人體生命活動引起的體表微動所調制,使得回波信號的某些參數(如頻率、相位)發生改變,檢測到這些變化就能從中提取出人體的生命參數(如呼吸或心跳) 。
  3. Our results indicate interactions among earthworms, organic matter, and soil microbial activity that should alter the carbon and nutrient balance of northern hardwood forest surface soils, relative to non - invaded soils

    我們的結果顯示土壤在有蚯蚓,有機物,以及微生物的相互作用下將會影響到北部闊葉林表面的營養物質和碳含量的平衡,這些只是相對于沒有受到侵襲的土壤來說的
