交换

However, the exchange bias field is influenced by the magnitude andthe direction of the stress, the magnitude of biquadratic coupling field, and the angleof the ferromagnetic and antiferromagnetic easy axes.

结果表明交换偏置场依赖于外磁场的方向，而与其大小无关；此外应力场的大小和方向，双二次耦合场的大小以及铁磁和反铁磁易轴间夹角均对系统的交换偏置场有影响。

In order to clearly understand the nature of exchange bias of the FM/AFMbilayers, we first discuss the influence of the biquadratic coupling field on both thehysteresis loops and the dependence of exchange bias field on the applied magneticfield angle.

为了更加清楚地认识铁磁／反铁磁双层膜中交换偏置的本质，我们首先研究了双层膜界面中双二次耦合对磁滞回线和交换偏置场随外磁场角度变化曲线的影响。

The result shows: the maximum of the exchange bias field moves towardsthe easy axis with increasing the biquadratic coupling field or bilinear coupling field;additionally, the oscillations of the curves for the angular dependence of exchangebias field become weak and gradually resembles the sine function with increasing thebiquadratic coupling field.

结果发现：双线性耦合或双二次耦合的增加都可使交换偏置场的最大值位置向易轴方向靠近，并且双二次耦合的增加使交换偏置场随外磁场的角度变化曲线的振荡也随之减弱，变为类似于正弦函数的图象。

Let R be an arbitrary commutative ring with identity, gl the general linear lie algebra over R consisting of all n × n matricesover R and with the bracket operation = xy -yx, t the lie subalgebraof gl consisting of all n×n upper triangular (resp., strictly upper triangular ) matrices over R and d the lie subalgebra of gl consisting of all n×n diagonal matrices over R.

在第三章中，对R是交换环的情形，讨论了典型李代数的导子代数的结构问题：设R是一个含幺交换环，gl是R上一般线性李代数。t是gl的所有n阶上三角矩阵(相应地，严格上三角矩阵)构成的子代数，d是gl的所有n阶对角阵构成的李代数。

It is proved that the model of Hertz, Capon and Lindel"of areidentical to Vakonomic model while the model of H"older, Pars andChaplygin are identical to Chetaev's model. The fact thatVakonomic model and Chetaev's model exist simultanously can betraced back to the early days of non-holonomic mechanics. These twomodels cause two problems the d- and - permutable problems.

论证了Hertz， Capon和Lindel"of的工作与Vakonomic模型相吻合，而H"older， Pars和Chaplygin的工作与Chetaev模型相吻合，Vakonomic模型和Chetaev模型两类模型并存的局面可以追溯到非完整力学发展的初期。1mm说明了伴随两类模型并存的现象而出现的两个问题 d-交换性问题和-交换性问题。
