If monotony tries me , and i cannot stand drudgery ; of stupid people fret me and little ruffles set me on edge ; if i make much of the trifles of life , then i know nothing of calvary love 若我受不了单调的生活乏味的工作;若愚笨的人叫我厌烦,一丝丝涟漪微波便破坏了我心湖的平静，一点生活中的琐事便叫我小题大做，那我就还是丝毫不懂加略山的爱。
However the study of metal - oxide hetero - interface is relatively less because the properties of metals and oxides usually differ extremely from each other . contrary to metals , the oxides are usually very brittle , elastically stiffer , insulating and exhibit less thermal expansion and their crystal lattice constants are different from metals . moreover , the preparation of specimen of metal - oxide interface is very difficult , the observation of searching a suitable interface under the electron microscope is also a tedious work 然而，对金属-氧化物界面结构的研究却相对少一些，这主要是由于金属与氧化物之间的性质相差非常大，与金属相反，氧化物通常很脆、绝热、热膨胀系数小，晶格常数也不同于金属，有的甚至相差很大，而且，制备金属-氧化物界面比较困难，在电子显微镜下全面地观察一个合适的界面也是一项令人乏味的工作。
