Introduction Higher efficiency of sustainable energy has become an indispensable to the low carbon economy.With the development of science and technology, people gradually recognize the characteristics of the micrometer and nanometer heat exchangers.I n 1981,Tuckerman and Pease[1] were the first person who come up with micro-channel heat exchanger.In 1985,Swife,etc.[2] invented a cross flow micro-channel heat exchanger which maximized heat transfer from a liquid (water-glycol) to a gas(air).Traditional small size channels can result in great pressure drop and uneven distribution of the temperature, which may decrease the working performance of the equipmeng when the exchanger applied to cooling the electronic parts of the device.

But the Preisach model involves the physical characteristic of magnetostrictive materials, it is complicated, and is not suitable for modeling GMA across a wide frequency band because the hysteresis characteristic is rate-dependent.
In this method, in order to converts the multi-valued function in one-dimension space into the single value function in the high dimension space, the original one-dimension input space is first projected on a high dimension input space, so that IOLS-SVM can be used to approximate the hysteresis characteristic. 1 Hysteresis Nonlinearity of GMA The GMA is manufactured by School of Materials Science and Engineering of BUAA[10].

Al-Pb is a traditional immiscible alloy system on which some important alloys such as bearing and solder materials are based[2].
Recently, significant progress has been achieved in computational materials science, and , as a powerful tool, molecular dynamics (MD) simulation has been widely used to observe and characterize the cluster formation and evolution of special systems[3-7].
