为预防电站锅炉裂纹或爆裂，需要建立电站锅炉生命期致裂因素集并了解其致裂机制。搜集了大量出自不同电站锅炉裂纹实例并对其成因进行了分类分析，以寻求电站锅炉的致裂因素、致裂机制及其与锅炉生命期阶段的关联性。对192例电站锅炉裂纹致裂因素分析发现，51%的锅炉裂纹与制造阶段相关，47%与安装使用阶段有关。
為預防電站鍋爐裂紋或爆裂，需要建立電站鍋爐生命期緻裂因素集併瞭解其緻裂機製。搜集瞭大量齣自不同電站鍋爐裂紋實例併對其成因進行瞭分類分析，以尋求電站鍋爐的緻裂因素、緻裂機製及其與鍋爐生命期階段的關聯性。對192例電站鍋爐裂紋緻裂因素分析髮現，51%的鍋爐裂紋與製造階段相關，47%與安裝使用階段有關。

In order to prevent the cracks of power boiler, it is necessary to ifnd the reasons of crack and utilize the set of fracturing factor in the life period of power boiler. For this reasons, a lot of examples of cracks from different power boilers are collected and classiifed, the relation of the fracturing factors and fracturing mechanism with stages in the life period of boilers are found in the article. By means of counting and analyzing the fracturing factors on 192 power boilers, it is discovered that 51%of cracks are related in manufacturing stage of power boiler, 47%with installation and use stage.
