以3号锅炉为例，该区域有效桩长为44米，也就是说，卸压孔孔深应大于29

以3号锅炉为例，该区域有效桩长为44米，也就是说，卸压孔孔深应大于29.3米才能起到良好压力释放作用

結果 (英文) 1:

In 3rd boiler, for example, in the region of 44 metres effective length, that is, pressure relief hole depth should be greater than the 29.3 m in order to play a good stress release

結果 (英文) 2:

In the 3rd boiler, for example, in the region effective length of 44 m, that is, pressure relief hole hole depth should be more than 29.3 meters in order to play a good role in pressure release

結果 (英文) 3:

No. 3 boiler as an example, the area of effective pile long for 44 meters, that is to say, the pressure relief hole depth should be greater than 29.3 meters in order to play a good pressure release
