战后的

God bless the Union; it is dearer to us for the blood of brave men which has been shed in its defenses The spots on which they stood and fell; these pleasant heights; the fertile plain beneath them; the thriving village whose streets so lately rang with the strange din of war; the fields beyond the ridge, where the noble Reynolds held the advancing foe at bay, and, while he gave up his own life, assured by his forethought and self-sacrifice the triumph of the two succeeding days; the little streams which wind through the hills, on whose banks in aftertimes the wondering ploughman will turn up, with the rude weapons of savage warfare, the fearful missiles of modem artillery; Seminary Ridge, the Peach Orchard, Cemetery, Culp, and Wolf Hill, Round Top, Litttle Round Top, humble names, henceforward dear and famous-no lapse of time, no distance of space, shall cause you to be forgotten.

联邦得上帝的保佑，得勇士们为之洒血捍卫，我们对它无不感到弥足珍贵。峥嵘岁月，沧海桑田，他们曾经战斗并倒下的地方依旧；那些恬美的高地依旧；街巷里不时回响着战火喧嚣的村落也又灯火依旧；战地外的原野依旧，在那里英武的雷诺将军曾经抵御进攻的敌人，并以自己的远见卓识无私献身确保了后来两天的胜利；环绕山岗的溪流依旧，溪流岸边走来战后悠闲的耕夫，拎着残酷战场遗留下来的粗陋武器和可怖的弹片炮灰； Seminary Ridge， the Peach Orchard， Cemetery， Culp， and Wolf Hill， Round Top， Litttle Round Top，无名的，及后来的有名的，这一切都让你们感到自己的渺小。

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。
