Contracture occurs when the efflux of calcium is prevented by removing the extracellular sodium . 如果除去细胞外液的钠而阻止钙外流，就会出现肌肉挛缩了。
One might anticipate that calcium efflux, like that of sodium, is mediated by an atp-dependent pump . 人们可以推测，钙的外流象钠一样是由ATP依赖的泵来完成。
Sodium, potassium and chloride, along with phosphates and bicarbonates, function to maintain homeostasis . 钠、钾和氯与磷酸盐、碳酸氢盐在一起，起着维持体内稳衡的作用。
Grass does not look green under sodium lighting because there is no green light for it to reflect . 青草在钠光照射下并不呈现绿色，就因为钠光中没有绿光成份可以被它反射。
The repulsion observed was great enough to cause the two beams to diverge rather than to cross inside the sodium cell . 已观察到的排斥大到足以使两束光叉开，不从钠室内穿过。
The development of sodium absorption capacity by aging beet slices, however, does not require calcium . 然而，随着甜菜薄片的衰老，要提高钠离子的吸收能力，已经无需钙参与作用了。
If one sodium ion is ejected from the cell in exchange for one external potassium ion, the pump is electroneutral . 如果从细胞内驱出一个钠离子由外部换回一个钾离子，则此泵是电中性的。
Such symptoms are likely to appear on plants growing in soils low in sodium, or when the plants exclude sodium . 这些症状和生长在钠含量低的土壤上的植物或排斥钠的值物所表现的症状相似。
Sodium, sulfate, magnesium, calcium, carbonate, bicarbonate, chloride, and boron should be determined in a water analysis . 水质分析要测定钠、硫、镁、钙、碳酸盐、重碳酸盐、氯和硼的含量。
They analyzed their samples for lead, sodium, copper and found that some of the ratios were close to the values found for the earth's crust . 他们分析了样品中铅、钠、铜，发现某些比率接近于地球外壳中的值。
