instruments of testing heat check, stress and linear shrinkage of casting alloy at present are not only inconvenient in operation but also unitary in function.───的测定铸造合金热裂、应力、线收缩参数的仪器不仅操作不便，而且功能单一。

Before starting the machine back check condenser is clean, to avoid bad heat.───开机前须检查机台背面冷凝器是否干净，以免散热不良。

A new multifunctional device for testing linear shrinkage, stress and heat check of casting alloy easily and quickly is developed in the paper.───本文研制一种新型铸造合金线收缩-应力-热裂特性多功能测定仪，它可以方便准确的测定金属热裂、应力、线收缩特性。
