求翻译：弹簧的工作温度升高，弹簧材料的弹性模量下降，导致刚度下降，承载能力变小。因此，在高温下工作的弹簧必须了解弹性模量的变化率（值），计算弹簧承载能力下降对使用性能的影响。按照GB1239规定，普通螺旋弹簧工作温度超过60℃时，应对切变模量进行修正，其公式为：Gt=KtG 式中G——常温下的弹性模量；Gt——工作温度t下的切变模量；Kt——温度修正系数按表2—98选取。是什么意思？

Spring temperature, spring elastic modulus decreases, resulting in stiffness decreased the carrying capacity is smaller. Therefore, the springs work at high temperatures must be aware of the rate of change of the modulus of elasticity (value) to calculate the spring carrying capacity decline on the

Spring temperatures rise, decline in spring the elastic modulus of the material, resulting in decreased rigidity and bearing capacity of small. Therefore, spring must be aware of the work of modulus of elasticity at high temperature rate of change (value), used to calculate the spring decreased load
