我们还剩下一个，异核双原子分子的例子没讲，这里组成分子的原子，是不同的。
And where we had left off was we were going to start one example of thinking about now where we have a heteronuclear diatomic molecules, so two different atoms in terms of forming the molecule.
任何异核双原子分子必然具有偶极矩，因为它的两端是不同的。
Any heteronuclear diatomic molecule must have a dipole moment since its two ends are different.

After extraction separation of gold by MIBK, lead, copper, iron, nickel in gold plating bath were determined by inductively coupled plasma-atomic emission spectrometry (ICP-AES).
如果能以乙酸与丙烯直接酯化一步合成乙酸异丙酯，则是一条理想的原子经济反应工艺路线。
If the synthesis of isopropyl acetate was manufactured by acetic acid and propylene, it would be a perfect atom economical technical route.
以三异辛胺萃淋树脂为微型柱固定相，采用流动注射在线预浓集与火焰原子吸收法联用技术，对微量钯的测定进行了研究。
A flow injection on line extraction chromatographic separation and preconcentration system is proposed for the determination of trace palladium by flame atomic absorption spectrometry (FAAS).
在最后，我们会看一个，异核双原子分子的例子。
Then at the end, we'll look at an example with a heteronuclear diatomic molecules.
