Dielectric permittivity measurements are reported for cysts of Artemia, a crustacean known as the brine shrimp. Using coaxial and waveguide techniques we examined the frequency range from 0.8 to 70 GHz. Taking advantage of the ability of this system to reversibly lose essentially all intracellular water, we determined the permittivity over the entire range of cyst water contents. Although experimental errors prevent a rigorous treatment of the data, we advance the general conclusion that little of the water in this system behaves dielectrically like pure water, regardless of water content. This conclusion is supported by, and is consistent with, the results of previously published studies that probe the motional properties of water in this system using nuclear magnetic resonance spectroscopy and quasi-elastic neutron scattering.
本文报道了卤虫（一种被称为盐水虾的甲壳类动物）囊肿的介电常数测量结果。我们使用同轴和波导技术，在0.8至70 GHz的频率范围内进行了检测。利用该系统可逆地失去几乎所有细胞内水分的能力，我们测定了囊肿水分含量全范围内的介电常数。尽管实验误差使得无法对数据进行严格处理，但我们得出一个普遍结论：无论水分含量如何，该系统中几乎没有水的介电行为类似于纯水。这一结论得到了先前发表的研究结果的支持，并且与这些研究结果一致，这些研究使用核磁共振光谱和准弹性中子散射来探测该系统中水的运动特性。
