负电荷

When, for instance, an ebonite fountain pen is rubbed with a silk handkerchief some of the atoms in the silk have one or two of their electrons knocked off.

举例 来说，当我们用一块丝手帕擦摩一支电木自来水笔时，丝绸中某些原子的一两个电子便会被擦掉，掉落下来的电子聚集在钢笔上使钢笔带上了一些多余的电子，从而产生了多余的负电，或者说一个负电荷。

Effect of negative electrets enhancing cell growth and increasing cell surface charge was in proportional to the surface potential of electret.

2成纤维细胞表面负电荷和S期内细胞数的增加量与驻极体的表面电位成正比。

The results showed that the TEAOH possessed stronger framework-directing function during the synthesis process of SAPO-34 molecular sieve, and took up more electronegative framework positions while the morpholine mainly filled the micropore system of SAPO-34 molecular sieve.

结果表明，TEAOH在导向生成SAPO-34分子筛骨架过程中表现活跃，占据了较多的平衡骨架负电荷的位置，而吗啉主要起到填充分子筛孔道的作用。

Gold nanoparticles was self-assembled onto a platinum electrode to form a negatively charged surface, and cationic dye-thionine was linked by Au—S and Au—N covalent bond and electrostatic adsorption as an electron transfer mediator.

在铂电极上自组装一层纳米金，构建负电荷的界面，然后通过金-硫、金-氮共价键合作用和静电吸附作用自组装一层阳离子电子媒介体硫堇。

The presence of CrO42- induced increase in negative surface charge and decrease in positive surface charge of two variable charge soils.

对两种可变电荷土壤的研究结果表明，加入铬酸根(CrO42-)能增加土壤的表面负电荷，减小土壤的表面正电荷的量。

The ionizer can keep the NAIs concentration above 3.02×105 ions/cm3 in the breathing space. This study investigated the distribution of control efficiency for four kinds of bioaerosols, and compared the difference of them.

研究结果发现，空气负离子在呼吸范围中的浓度分布在面部前方5 cm处最高，随与空气负离子产生源距离增加而衰减，由於面部会中和负电荷，故也会使空气负离子浓度骤减。

Kasper had discovered that two of these eight polysaccharides have a unique zwitterionic structure: the molecules have both positive and negative charges on each repeating unit.

卡斯皮尔发现二这八多聚糖有一个独特的zwitterionic结构：分子有在每个重复的单位的正面和负电荷。

The article focuses on the teaching of circuitry,from the basic concept,discusses the direction of the voltage or the electric current in different situations such as Ohm′s law,Kirchhoff′s law,Superposition theorem and so on.

结合在多年的教学，本文针对不同的情况电压和电流的方向做了探讨。1电流电压的实际方向和参考方向习惯上把电流的方向定义为正电荷运动的方向或负电荷运动的相反方向，而把电压的实际方向定义为电位降的方向。
