Change of sodium pump activity is involved in hypoxic injury in rat cortical neurons. High affinity sodium pump is re lated to the protection of hypoxic injury and low affinity sodium pump is related to the hypoxic injury.

Na，K-ATP酶活性改变参与了皮质神经元的缺氧性损伤，其中高汞和力Na，K-ATP酶与皮质神经元缺氧性损伤保护作用有关，而低亲和力Na，K-ATP酶则与其缺氧性损伤有关。

Mercury alone is not the cause of all of these symptoms, but it is the spark that sets off a cascade of damage in the body.

单凭汞不是所有这些症状的原因，但它是引发体内一连串损害的火花。

So it is meaningful for environmental, biological, medicinal to study the speciation analysis for mercury.

因此研究测定环境中汞的形态的分析方法具有重要的环境科学、生命科学及医药科学意义。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.
