In the meantime the Chinese air force's combat capability has also been greatly enhanced and the Sino-Soviet pilots in a number of air began to fight side by side. October 24 1951 34 U.S. planes bombed sunchon Bridge the Sino-Soviet Air Force MiG-40 aircraft took off against the same time the U.S. shot down an F-84 fighter jets and a B-29 bombers. October 30 56 are in operational status of Sino-Soviet Mig -15 aircraft chongchon-gang over against by the 21 B-29 aircraft and 200 fighter escort composed of the U.S. fleet shooting down 12 B-29 aircraft and four aircraft F-84 aircraft.

在此期间，中国空军的作战能力也大大增强了，中苏飞行员在许多空战中开始并肩作战。1951年10月24日，34架美国飞机轰炸顺川大桥，中苏空军共40架米格飞机同时起飞迎战，击落美国1架F—84战斗机和1架B—29轰炸机。10月30日，56架处于战备状态的中苏两国米格—15飞机在清川江上空迎战由21架B—29飞机和200架护航战斗机组成的美国机群，击落12架B—29飞机和4架F—84飞机。

By the early 1950s, with most fighters equipped with either refueling receptacles or probes, the first large-scale overseas deployments began. In July 1952, KB-29s supported the deployment of fifty-eight F-84Gs of the 31st Fighter Escort Wing from Turner AFB, Georgia, to bases in Japan. Three months later, seventy-five F-84Gs flew from Bergstrom AFB in Texas to Misawa Air Base in Japan.

到上世纪50年代初期，在大多数战斗机都装备了受油口或者是探头的情况下，首次大范围的海外部署开始了。1952年7月，KB-29加油机支援了第31战斗机护卫联队58架F-84G型战斗机从佐治亚州特纳空军基地到日本基地的部署行动。3个月后，75架F-84G从得克萨斯州的博格斯托姆空军基地飞往日本的三沢空军基地。

In this paper,by using the idea of F-expansion method (where F is a known solution of an ordinary differential equation with fourth positive power nonlinearity),the problem of seeking the exact solutions of the generalized BBM equation with any positive power nonlinearity is changed into seeking the exact solutions of an ordinary differential equation with fourth positive power nonlinearity.
