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。

A series of homemade needles and guides for underlying guided suture was used to treat the skin laxity in 42 cases of facial paralysis and 15 cases of facial aging science 2006. All of them were used the suture technica of deep-seated suspensory . Results 40 in 42 facial paralysis cases obtained satisfactory effect, and the effect of them were steady in 6 to 12 months followed-up .

自2006年以来我们采用自行设计的李氏埋没导引缝合针和李氏埋没导引缝合器，以埋没导引的方法，通过深部组织缝合悬吊的技术治疗面神经瘫痪遗留的面部表情不对称42例，其中完全性面瘫31例、部分性面瘫11例；治疗面部老化造成的皮肤松垂15例。

The multi-dimensional signals measured by sensors with a machine working under normal condition or fault condition, can be used to build Q statistic and T^2 statistic respectively to detect the state of the machine. Meanwhile, the feature vector is constructed by the Q value and the T^2 value, the geometrical distance between the normal feature vector and the feature vector H when the machine goes wrong is used to realize the fault location. The results show that the method is feasible.
