Methods:Using inductively coupled plasma mass spectrometer (ICP MS)and inductively coupled plasma atomic emission spectrometer (ICP AES)to examine changes of La 3+ ,Ce 3+ ,Pr 3+ ,Nd 3+ and Calcium contents.

• 方法 :采用电感耦合等离子体质谱法和电感耦合等离子体原子发射光谱法分别检测孕鼠和胎鼠肝中镧 ( La3 + )、铈 ( Ce3 + )、镨 ( Pr3 + )、钕 ( Nd3 + )和钙含量变化。
