负电

Usually, the nucleus is positive, electrons are negative.

通常情况下, 原子核带正电, 电子带负电.

Outward currents therefore increase electronegativity in the cell interior.

外向电流因此能增加细胞内的负电性.

Including electrostatic field, the negative electric field, the-frequency field, high frequency anions, such as-infrared.

包括有静电场 、 负电场 、 低频 场 、 高周波、负离子 、 远红外等.

Salt is made of two ions: positively charged sodium and negatively charged chloride.

盐是由带正电的钠离子和带负电的氯离子构成的.

However, many classes of oligonucleotides are polyanions, so they cannot cross over cell membrane.

但是, 大多数此类化合物是呈负电性的, 不能有效跨越细胞膜.

Objective To study the adsorbability of tripeptide serine aspartic glutamic acid ( SDE ) for low density lipoprotein ( LDL ).

目的研究丝氨酰-天冬氨酰-谷氨酸 ( SDE ) 负电性三肽仿生吸附剂对低密度脂蛋白 ( LDL ) 的吸附.

Therefore the whole atom is neither positive nor negative.

因此,整个原子,既不带正电,也不带负电.

Dusty plasmas consist of electrons, ions and usually negatively charged dusty micro-particles.

其基本成分除了电子和离子外,还包括通常带负电的尘埃微粒.

As these electrons are negatively charged they will attempt to repel each other.

因为这些电子都是带负电荷的，它们会互相排斥。

The drops are usually negatively charged, but occasionally one with a positive charge is found.

这些油滴一般都带负电, 但偶尔也发现有带正电的.

A body is negatively charged when it has electrons in excess of its normal number.

物体所含电子超过其正常数目时,该物体就带负电.

Thus, glass becomes positive, while the silk with which the glass was rubbed becomes negative.

例如, 玻璃与丝绸摩擦时,玻璃带正电, 而丝绸带负电.

Opposites ( positive and negative ) attract , so the objects pull together. This is static electricity.

彼此 ( 正电及负电 ) 互相吸引就会导致物体相吸, 这就是所谓的静电.

Hyperpolarization and repolarization both describe increased electronegativity within the cell.

超极化及再极化都表明细胞内负电性的增强.

Objects and as a result of friction with the electricity, is not positive is negative.

物体因摩擦而带的电, 不是正电就是负电.
