reverse charge

To avoid any problems, make your calls from a public phone, make reverse charge calls to overseas, or use a telephone card.

为防意外，可使用公用电话，以对方付费方式打国际长途，或者使用电话卡。

The electric charge of the anionic gelatin plays an important role in reverse gene transfection system by affecting the release pattern of the gene complexes and the adsorption of serum protein to the substrate.

阴离子化明胶的带电性与反向转染体系的转染效率密切相关，所带负电荷的多少可以影响到基因复合物的释放过程，以及血清蛋白在表面上的吸附量。

I didn't have any money so I had to call reverse-charge.

我那时没钱，所以只好打对方付费电话。

The analysis shows that Schottky emission mechanism and ohmic conduction contribute to the current in the film under the lower forward biases and the lower reverse biases respectively, while the current is induced mainly by Frenkel-Poole emission mechanism and space-charge-limited current under the higher forward biases.

分析表明，在较低的正向偏压和反向偏压下，电流输运机制分别为Schottky发射和欧姆输运电流；而在较高的正向偏压下，Frenkel-Poole发射和空间电荷限制电流两种机制共同作用。
