China Railways AM2. The China Railways AM2 class steam locomotive was a class of 4-4-0 steam locomotives operated by the China Railway, built by the Baldwin Locomotive Works in the United States in 1879.

These locomotives were originally built for the Imperial Railroad of North China, which later became known as the Peking−Mukden Railway, and subsequently the Beining Railway; at the time of their introduction, they counted amongst the most modern locomotives of the time. After the Japanese occupation of northern China, the collaborationist Provisional Government of the Republic of China nationalised all railways in its jurisdiction, creating the  North China Transportation Company in 1938 to operate the railways in the region. The NCTC designated these locomotives 'Ameni (アメニ) class.

After the end of the Pacific War, these locomotives were passed on to the Republic of China Railway. After the establishment of the People's Republic of China, China Railways designated them ㄚㄇ2 (AM2) class in 1951, and subsequently AM2 class, in Latin letters instead of Zhuyin script, in 1959.

Landau–Levich problem. In fluid dynamics, Landau–Levich flow or the Landau–Levich problem describes the flow created by a moving plate which is pulled out of a liquid surface. Landau–Levich flow finds many applications in thin film coating. The solution to the problem was described by Lev Landau and Veniamin Levich in 1942. The problem assumes that the plate is dragged out of the liquid slowly, so that the three major forces which are in balance are viscous force, the force due to gravity, and the force due to surface tension.

Problem

Landau and Levich split the entire flow regime into two regimes, a lower regime and an upper regime. In the lower regime closer to the liquid surface, the flow is assumed to be static, leading to the problem of the Young–Laplace equation (a static meniscus). In the upper region far away from the liquid surface, the thickness of the liquid layer attaching to the plate is very small and also the since the velocity of the plate is small, this regime comes under the approximation of lubrication theory. The solution of these two problems are then matched using method of matched asymptotic expansions.
