同质二像

The traveller from the coast, who, after plodding northward for a score of miles over calcareous downs and corn-lands, suddenly reaches the verge of one of these escarpments, is surprised and delighted to behold, extended like a map beneath him, a country differing absolutely from that which he has passed through.

那个从海岸走来的游客，向北面跋涉了二十几英里的路程，才走完白垩质的草原和麦地。他突然走到一处悬崖的山脊上，看见一片田野就像一幅地图铺展在下面，同他刚才走过的地方决然不同、不禁又惊又喜。

Church leaders often behave as if Italy were still as homogeneously Catholic as in the days when every Italian home had a crucifix above the marital bed and a black-and-white television from which Pius XII would occasionally bestow a restrained wave.

教会领导人常常认为意大利仍是一个像当年一样同质的天主教国家，那个时候，每一个意大利家庭都在婚床上方安置一个十字架，并拥有一台黑白电视机，教皇庇护十二世偶尔在电视里面向大家来一次拘谨的挥手致意。5月12日，教会团体集合了数万民众参加罗马的一个家庭日，巴尼亚斯科大主教踌躇满志地宣称这是&社会用一种毫不含糊的方式表达自己&。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
