Therefore, the thesis emphasized on the design of high efficient switch power supply controller, especially the improvement of the efficiency under light load condition.

有鉴于此，论文重点围绕高效率开关电源控制芯片的开发，尤其是轻载条件下提高开关电源效率的技术开展研究。

Light Weight: Under the same condition heat insulation, the replacement of partial brick wall or concrete with IGU can reduce load of building and simplify building structure.

重量轻：在隔热效果相同条件下，用中空玻璃代替部分砖墙或混凝土墙，可减少建筑载荷，简化建筑物结构。

Hardness and abrasion resistance property are improved, the abrasion resistance property of the composite is better under the light-load condition than under the heavy-load condition.

复合材料的硬度和耐磨性均提高。轻载条件下，复合材料的耐磨性能更好。
