nias

For example , after the Indian Ocean tsunami , it was only three months before the next big earthquake hit the island of Nias in2005 .

Riyadi说，没有办法准确地预测下一场地震。例如，在印度洋海啸之后，只过了3个月下一场大地震就于2005年袭击了Nias岛。

Many sulphides , selenides , and tellurides have the nickel arsenide 's NiAs type of structure .

许多硫化物，硒化物和碲化物具有砷化镍NiAs型的结构。

They all belong to NiAs type and are relatively high in Ni + Cu + Co , being similar to the composition of pyrrhotite in mantle-derived inclusions .

其基本结构主要为NiAs型，具有较高的Ni+Cu+Co含量，与相应的地幔包体成分相近。

Based on total energy calculation , mechanical stability judgment , X ray diffraction simulation , and hardness calculation , we conclude that the experimentally-synthesized OsC should be in NiAs structure not in WC structure .

通过总能量计算、稳定性判断、X射线衍射模拟结果分析及硬度计算，我们认为实验中合成的OsC应具有NiAs结构而不是WC结构。
