polydomain

(2)多畴构的出现可温度梯度方向的变化。

Second, the emergence of polydomain structure can be attributed to the variation of direction of temperature gredient.

The 'thermal hysteresis' of first-order ferroelectric phase transitions and the polydomain structure of ferroelectrics can be explained on the basis of the principle of minimum entropy production.
