The rigidity of a dilutely dispersed system of spherical particles having an elastically anisotropic shell is theoretically obtained in the case of material incompressibility. Considering characteristics of biological cells the complex intrinsic viscosity [eta*] of this system is numerically calculated in the case that the medium and the inside region of the shell contain viscous liquids and the shell region is made of an elastic substance. In [eta*] vs. frequency curves anomalies occur at some range of anisotropic parameters. This anomaly may be called a negative relaxation, when the relaxation strength takes a negative value.
在材料不可压缩的情况下，从理论上得出了具有弹性各向异性壳层的球形颗粒稀分散体系的刚性。考虑到生物细胞的特性，在介质和壳层内部区域包含粘性液体且壳层区域由弹性物质构成的情况下，对该体系的复本征粘度[η*]进行了数值计算。在[η*]与频率的曲线中，在各向异性参数的某个范围内会出现异常。当弛豫强度取负值时，这种异常可称为负弛豫。
