the Limit of Heat

While existing federal law Yucca in terms of tons of waste, the real limit is heat.

当前联邦法律是在废料吨数上对雅卡山进行限制, 其实真正的限制应是是热量.

The Limit of Heat shows that scorching summer days will soon be gone.

处暑表示炎热的天气快要过去了。

The Limit of Heat: It means the scorching summer is going to pass by.

处暑: 处暑表示炎热的夏天快要过去.

The temperature upper limit was determined with 1st stage temperature shrinkage curve of the film, which can ensure the heat-sealing strength and reduce the heat-sealing time, reduce the damage rate, and ensure the beauty of the sealing line.

确定了对于共挤薄膜的热封温度应取温度收缩曲线的一阶段作为上限，并在保证封口强度的基础上，应减少热封时间，可以有效地减少破损率，保证封合处的表面美观。

Meanwhile, temperature characteristic and velocity of oxygen consumption are also studied by full-scale experiment. Using conversation of energy and estimation of chemical bond energy to obtain heat release of coal sample, the limit parameters of self-ignite of coal sample are made sure.

通过大煤样自然发火实验研究了煤样的升温速度特性、耗氧速度特性，采用能量守恒和化学键能估算法计算了煤样的放热强度，确定了煤样的自燃极限参数。

A major challenge scramjet engines currently faced is the high aerodynamic heat load. The wall temperature of combustion chamber without cooling can reach 3000K, which exceeds the limit of the general material used.

超燃冲压发动机目前面临的一大难题就是极高的气动力热载荷，燃烧室壁面温度在未经冷却的情况下能达到3000K。这超过了一般结构材料的使用极限。
