谁帮我改改这句话的语法
When temperature is below 0℃,there is tensile stress in inorganic glass and compressive stress in organic glass.
我想说的意思是当温度低于0度时,无机玻璃里有拉应力,有机玻璃里有压应力

原句语法没有多大错误.不过,从句中温度特指下文中玻璃的温度,因此应该加定冠词 the；主句中的 stress 前有描绘性形容词作定语,抽象名词已经具体化为区别于其他类型的压力,所以要加上不定冠词 a 表示种类,即——
When the temperature is below 0℃,there is a tensile stress in inorganic glass and a compressive stress in organic glass.（根据主谓一致的邻近原则,不能用楼上所说的 there are）
根据上下文的文理要求,还可以有以下几种说法供参考——
1、If the temperature is below 0℃,there is a tensile stress in inorganic glass and a compressive stress in organic glass.（表示试验中给予条件）
2、When the temperature arrives at below 0℃,there well be a tensile stress in inorganic glass and a compressive stress in organic glass.（表示由高向低变化到零度以下）
3、When the temperature tends to below 0℃,a tensile stress produces/appears in inorganic glass and a compressive stress (省略前面出现过的动词) in organic glass.（温度趋于零度以下时,无机玻璃里产生/出现拉应力,有机玻璃里产生/出现压应力）
When temperature is below 0℃, there are tensile stress in inorganic glass and compressive stress in organic glass. is---------------are
