Magnetization and coercivity in Co/Pt multilayers with constant total Co layer thickness NIE Ying(聂 颖)1, 2 , YANG Xin(杨 鑫)2 , ZHANG Pang(张 鹏)1, SANG Hai(桑 海)1 1. National Laboratory... components parallel and perpendicular to the applied field. A dependence of the coercivity of Co/Pt multilayers on the Co layer thickness was reported, in which the total thickness of Co layers kept......
efficiency has practical significance only when the flow is more than 50% of the total flow [13]. By considering the energy efficiency potential of GWSHP, the variation range of flow rate is from 50% to 100...J. Cent. South Univ. Technol.

According to the virtual work principle, the difference theorem and the variation method, the collapse surface of double-layer rock mass is determined based on the Hoek-Brown failure......
and initial cohesion of upper and lower soil mass are fixed, the change of the failure width is minor with the change of the thickness of single layer under the fixed condition of total buried depth... and initial cohesion of upper and lower soil mass are fixed, the change of the failure width is small when the thickness of single layer changes under a fixed condition of the total depth. 3) When......
of thickness distribution Considering the different initial thicknesses of the two tube segments, it is indistinct if using the ultimate thickness dimension to compare the thickness variation between two tube segments. However, thinning ratio can help to overcome this difficulty and is effective to compare the thickness variation. Represented by δ, thinning ratio can be calculated using equation......

Improvement of machining quality of copper-plated roll mold by controlling temperature variation Tae-Jin JE 1, Eun-Chae JEON 1, Sang-Cheon PARK 1, Doo-Sun CHOI 1, Kyung-Hyun WHANG 1, Myung-Chang.... The temperature variation around the roll mold also made thermal expansion of the roll mold. The amount of thermal expansion had strong relationship to the amount of pitch error. Therefore, the roll mold......
, the calculation processes of rock plug thickness are deduced by means of the upper bound theorem and variation principle. As a consequence, the expression of minimum safe thickness is obtained. 2) Influence...J. Cent. South Univ.
