3M i τi = 2 a i bi 3M i k = Ga i b i3 由后一式得 Gka i b i3 Mi = 3 60 Also Gk M =∑Mi = 3 i a i bi3 ∑ So we have: M a i b i3 = M 3 ∑ a ibi i Consequently we have:τ 3 Mb i = a i b i3 ∑ 3M k = G ∑ a i b i3 It is noticeable that: the shear stress of the midpoint of the long side of the narrow rectangle is considerably precise.

而 故有 Gk M =∑Mi = 3 M i a i bi3 ∑ a i b i3 = M 3 ∑ a ibi 从而有τ i 3 Mb i = a i b i3 ∑ 3M G ∑ a i b i3 k =值得注意的是：由上述公式给出的狭矩形长边中点的剪应力已相当精确，然而，由于应力集中的存在，两个狭矩形的连接处，可能存在远大于此的局部剪应力。

A mathemetical model of magnetic field in electromagnetic separation of inclusions from molten aluminum under rectangle coil and 50Hz current is presented according to the magnetic vector potential integral equation and the basic theory of magnetohydrodynamics. The magnetic field distribution in the gap of coils is simulated by the model and the actual magnetic field distribution also is measured. The experimental results show that the magnetic field distribution in the gap of coils is uniform and is consistemt with the model simulation. The magnetic field designed accord the simulated result is proved suitable in the practice.

摘 要：根据电磁流体力学的基本理论，利用矢量磁位积分，建立了在采用矩形电磁线圈和工频电源的条件下电磁分离铝熔体中夹杂的电磁场数学模型，模拟计算了电磁感应线圈气隙中的磁场分布状态，同时对制做的感应线圈的实际磁场进行了测量模拟计算磁场的分布状态与实际磁场的测量结果基本一致，都表明在电磁感应线圈气隙中磁场分布均匀，可以进行分离铝熔体中的非金属夹杂。

Uncertain temporal relations can be represented and reasoned by IA. IA has strong expressive ability in tense, and it can represent all natural temporal relations. At the same time, temporal relation represented by IA is highly visual and comprehensive. In additional, IA has been extended from one-dimension temporal area to two-dimension spatial area, that is to say, interval algebra can be developed to rectangle algebra for two-dimension reasoning.
