给以用以维持生活的财产

These are issues that concern us today:the prevention of war; the protection of the environment; the balancing of population and resources; the management of energy so that we will neither exhaust our resources with unbridled growth nor contaminate the environment; the distribution of resources among nations and groups who have been differently dower ed（给以用以维持生活的财产） in the past by nature and history; the humanization of technology so that technology can be used for human ends and not primarily for profit or for power; the replanning of towns and cities so that neighborhoods can again be a microcosm of three-generational wholeness of life; the creation of transcendental values that will no longer set members of one religion against another, or of one ideology against another, so that all human beings can move in new ways without being traitors to the old.

这些是今日和我们息息相关的问题：防止战争；保护环境；人口与资源的平衡；资源管理，以免人口激增而耗尽资源和污染环境；国家团体之间的资源分配，它们过去由于自然和历史因素而分配不均；科技的人性化，使科技能应用在人性化的目的上，而非只用于利益或权力之上；重新规划乡镇和都市，让邻里之间能够再度成为一个三代同堂、生活完整的小天地；创造超越性的价值观念，使得某个宗教信仰或是某个思想体系的人不在敌视异己，人们也就都无需为新弃旧。

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。
