在80 ~ 650 K温度范围内，用X射线衍射法测定了AgGaS 2和AgInS 2化合物的晶格常数α和c随温度的变化.这些数据用于计算垂直于主轴（α <$）和平行于主轴（α <$）的热膨胀系数，以及A <$C（αAC）和B <$C（αBC）键的热膨胀系数。结果表明，在几乎整个研究温度范围内，这两种化合物的膨胀系数α B和αBCare均为负值，而α C和α AC均为正值。
The lattice parameters α andcof the AgGaS2and AgInS2compounds are determined as a function of temperature by X‐ray diffraction method in the temperature range from 80 to 650 K. The data are used to evaluate the coefficients of thermal expansion, perpendicular (α⟂) and parallel (α∥) to the principal axis, and the thermal expansion of the AC (αAC) and BC (αBC) bonds. It is found that for the two compounds almost over the whole investigated temperature range the coefficients of expansion α∥ and αBCare negative while the coefficients α⟂ and αACare positive.
