We will carry out a full range of key energy-saving projects, including upgrading of low-efficiency coal-fired industrial boilers and furnaces and combined heat and power facilities.
全面实施低效燃煤工业锅炉（窑炉）改造、区域热电联产等重点节能工程。
Of course, their strength and heat resistance are low, restricted range of applications.
当然，它们的强度和耐热性都较低，应用的范围受到限制。
The results show that heat loss of MHP is mainly determined by gas conduction in high pressure range, while conduction through the supporting beams dominates in low pressure range.
分析结果显示，气压较高时微热板传热以气体导热为主，而气压较低时以支撑桥导热为主；
