  Mixed the composite particle polyaniline / BaFe_x(Ti_(0.5)Mn_(0.5))_(12-x)O_(19) and paraffine powder make sure that the particle and the powder quality ratio was 2:3. Then tested the mixture complex dielectric constant and complex permeability in the range of 2～18GHz.

  将合成的聚苯胺/BaFe_x(Ti_(0．5)Mn_(0．5))_(12-x)O_(19)复合粒子与石蜡粉末按一定质量比(试样粉末：石蜡=2：3)混合，在频率为2～18GHz的范围内测定样品的复介电常数和复磁导率。

  And the circular performance of paraffine is also stable. But the melting point and melting latent heat are influenced when paraffine has low hydrocarbon.

  从而得出,硬脂酸、棕榈酸及肉豆蔻酸无过冷现象,且循环性能较稳定,是可选用的太阳能热利用系统的相变储能材料;石蜡的循环性能也比较稳定,但是不纯的石蜡常常含有低链烃的物质,影响其熔点和熔化潜热。
