1988年，D．I．门捷列夫计量研究院（以下简称VNIIM）制造了高精密度的自动干涉膨胀计，用于考察热线性膨胀系数（以下简称TLEC）。膨胀计可以测量固体热线性膨胀系数从O．05×10-6～25×10-6K－1的样品，其中IDS－1MA膨胀计测定的温度范围为300～1500K，IDS－2MA膨胀计的测定
1988, D. I. The Mendeleev Institute for Measurement (VNIIM) manufactures a high-precision automatic interference dilatometer to investigate the thermal linear expansion coefficient (TLEC). Dilatometer can measure the linear thermal expansion coefficient of solid from O. 05 × 10-6 ~ 25 × 10-6K-1 samples, of which IDS-1MA dilatometer measured temperature range of 300 ~ 1500K, IDS-2MA dilatometer determination
