The Activated Ploy-oxygen Aerator adopts magnetic engineering technology to send the oxygen of air which is gathered and activated by polyoxier to the mixing chamber of main engine under water, and the process of water and oxygen synthesization is finished rapidly by the use of magnetizer and activated oxygen enriched air under water, which has been cut into tiny air bubbles by the high-speed rotated propeller of the mixing chamber in the process of water and oxygen synthesization, which can increase the affinity of water and oxygen. When flow rate of water is more than the buoyancy force of the tiny air bubbles, it is difficult for the tiny air bubbles to float on water in short time and the tiny air bubbles can stay in water for longer time, which can increase the efficiency of water dissolving oxygen and make the power efficiency of the machine is greater than traditional aerator obviously.

聚氧活化曝气增氧机采用磁性工程技术，将空气中的氧经聚氧器聚集活化后送到水下主机的混合室，由水下的磁化器和活化富氧空气快捷完成水气合成程序，在水气合成过程中已被混合室内高速旋转的离心叶轮切割成微小气泡，这些随射流、射向水下方的小气泡，其动能消耗至零后，在水中的浮力作用下、开始缓慢上升，由于提高了水与氧亲合力的小气泡只靠浮力沿着螺旋型的曲线缓慢浮升，这些小气泡在短时间很难浮上水面，因此延长了小气泡在水中的停留时间和行走路程，大大提高水中溶解氧的效率，使该机的动力效率明显高于传统曝气装置。

Shortly after the 1931 competition, an R engine using a special fuel blend powered the winning Supermarine S.6B aircraft to a new airspeed record of over 400 miles per hour (640 km/h). Continuing through the 1930s, both new and used R engines were used to achieve various land and water speed records by such racing personalities as Sir Henry Segrave, Sir Malcolm Campbell, and his son Donald; the last record was set in 1939.A 1951 R-powered water speed record attempt by Donald Campbell was unsuccessful.

在1931年比赛后不久，一台"R"发动机在使用一种特别的混合燃料做动力的情况下，使得一架获胜的休泼马林公司的S.6B飞机飞出了超过400英里1小时(640 km/h)的新记录，在随后的30年代里，崭新的和使用过的"R"发动机在亨利·西格雷夫，坎贝尔·马尔科姆爵士及他的儿子唐纳德·马尔科姆这些竞赛名人的手中创造了一系列的陆地及水面速度记录，最好记录于1939年创造，1951年唐纳德·马尔科姆尝试刷新R发动机载动的水上速度记录但没有成功。

In order to control labor effectively, British settlers inclined to adopt the extraeconomic compulsory means as well as economic ones under the influence of the racial labor relation of which boers were fond.

为了实现对劳动力的有效控制，英裔白人在布尔人一贯热衷的种族主义劳动力关系的牵引下，也趋向于在采取经济强制的同时，辅之以超经济强制的手段，英裔白人的种族主义正是在这一背景下浮出了水面。

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。
