但是，利用一种油性液体和水，以及在通道的一面覆盖上一层疏水物质，另一面覆盖上吸水物质，既可避免这一情况。
However, by using an oily liquid and an aqueous one, and by covering one side of the channel with a substance that repels water and the other side with one that attracts water, this can be avoided.
认为这些黑色覆盖物为脉冲电流在放电过程中，油性液体介质裂变产物(主要为碳黑)涂覆在裂纹内部形成的积碳。
The black material is considered as carbon deposition, which is formed by oily-liquid medium fission product (mainly carbon black) covering inside crack during the discharge process of pulse current.
向第一色谱柱(10)添加油性液体至获得多氯联苯类抽提液所需要的时间通常为2 ~ 10小时左右的短时间。
The time required for obtaining the polychlorinated-biphenyl extract after addition of the oily liquid to the first column (10) is generally as short as about 2-10 hours.
如果油性和水性液体的选择正确，就能用紫外线把一些层处理成透明多聚体，从而使这些液滴永久化。
The result is a “Russian-doll” droplet that, if the correct oily and aqueous liquids are chosen, can be made permanent by curing some of its layers into transparent polymers using ultraviolet light.
