VTF

The viscosities and conductivities of the twelve ILs were well fit by the VTF model over the temperature range studied ( 25-80 ℃).

12种离子液体的粘度、电导率与温度的关系在所研究的温度范围内（25-80℃）符合VTF模型。

Besides, VTF equation was applied in fitting and calculating the glass transition temperature of PVP when the heating rate is infinitesimal. The result is in accordance with the rule that the glass transition temperature lowers with the decrease of the heating rate.

还利用VTF方程拟合计算PVP在升温速率无限小情况下的玻璃化转变温度，结果与玻璃化温度随升温速率减小而降低的规律一致。

The relationship between conductivity and temperature is in accord with VTF equation.

电导率与温度的依赖关系符合VTF方程。

The Vogel-Tammann-Fulcher ( VTF) equation accurately describes the dependence of both of the conductivity and viscosity on temperature.

VTF方程很好地描述了粘度-温度及电导率-温度关系。

Results: Filter migration occurred in 6.7% ( 1/ 15) of the VTF. Vena cava thrombosis was seen in 6.7 ( 1/ 15) of the follow-up patients with a VTF.

结果：复查病例6.7%（1/15）的VTF发生移位，6.7%（1/15）的VTF内有血栓。
