采用静滴法测量并对比典型低膨胀硼硅酸盐玻璃和普通钠钙硅玻璃的熔体密度和表面张力。
In the present research, surface tension and density of borosilicate melts were measured and compared to that of Na-Ca containing glass melt using sessile drop method.
然而,通常热膨服系数高的封接玻璃软化温度低,而热膨胀系数低的软化温度偏高。
The soldering glass has a rather low coefficient of expansion as well as low sealing temperature.
