镧

Lanthanum praseodymium - cerium rare earth ( LPC ) was a patent composition.

镧镨铈混合稀土 （ LPC ） 是新型专利成分的混合稀土。

The activation mechanism of La ( III ) to the HRP was also discussed.

导致萤光发色基团所处的微环境也相应变化；并运用它推测了镧离子对该酶的激活作用机制。

Description: Lanthanum Nitrate is soluble in water and moisture in wet air.

说明： 硝酸镧溶于水，在潮湿的空气中易潮解。

Cerium showed more effective than lanthanum for vanadium tolerance of FCC catalysts.

氧化铈较氧化镧更容易与钒反应，因而具有更强的抗钒能力。

Li - doped lanthanum chromite powders in stoichiometric proportions were prepared by sol - gel process.

采用溶胶 - 凝胶法，按化学配比将锂元素掺入铬酸镧中制得粉末。
