If it rains cats and dogs, we'll cancel the outdoor activities tomorrow.

Unless it rains cats and dogs, I keep practicing in the morning everyday.

我每天坚持晨练，除非那天有倾盆大雨。

They agree like cats and dogs.

相处如猫狗，难以安宁。

The results showed that: ( 1) TiO2 promoted the sintering of chromic oxide by Ti4+ replacing Cr3+, which restrained the formation of high volatility chrome cation through forming chrome cation vacancy, and therefore caused lattice distortion and increased Cr3+ diffusion rate.

试验结果表明：（1）TiO2通过Ti4+置换Cr3+，抑制了高挥发性铬离子的形成，产生了铬离子空位及引起晶格畸变，增大了Cr3+扩散速率，从而促进了Cr2O3材料烧结。

The synergism between the ferrite spinel and γ-Fe_2O_3 which exist in catalysts for oxidative dehydrogenation of butene has been proposed and explained with cation/ anion vacancy.

通过对不同组成催化剂活性的研究，提出了催化剂中存在的铁酸盐尖晶石相和γ-Fe2O3相在氧化脱氢反应中的协增机理，并用阴/阳离子空穴加以解释。

For the former case, it starts from the mechanism proposed by Iida, taking into account the influence of cation vacancy upon the energy levels and wave functions of Co2+;

前者从Iida提出的物理机构出发，考虑了阳离子缺位对Co~（2+）能级和波函数的影响；

These anomalous of the Curie temperature variation are well analyzed by the cation vacancy model.

利用阳离子空位理论模型较好地解释了Curie温度变化的异常现象。
