However, the disadvantage of laser welding is the so - called post - weld - shift ( pws ). the end result is a reduction in light coupling efficiency. the shrinkage force generated by the solidification process is so great that no known mechanical structure can counteract the shrinkage from shifting the joint ? at least at the micron level
這種封裝技術最大的缺點是會使激光二極體的封裝產生焊後偏移（ pws ） ，很少有一種機械的方法可以校正這種焊後偏移到亞微米級別，目前激光錘被證明是一種很有效的校正方法，激光錘校正作用過程就是利用金屬熔化凝固冷卻產生的內應力來恢復焊後偏移的過程。 -
With the very low water to cement ratio, rpc has ultra - high strength high ductility and low permeability. in this paper, the compressive strength of rpc can reach to a high point with the number approximately 135mpa. as illustrated from the study results, we can approve some fundamental conclusions : there are big effects on rpc with deferent kinds and properties of raw materials and deferent curing conditions ; stress - strain curve shows the process of destroy with rpc samples ; x - ray diffraction analysis indicates that heat treatment at temperatures 90 accelerate the hydration of rpc sharply, therefore, mechanical and microstructural properties of rpc are highly dependent on heat treatment ; it is believed that rpc materials have excellent resistance to chloride permeability ; during the heat treatment, the shrinkage of rpc developed quickly because of chemical reactions ; the rpc with slag mostly has the advantage of rpc without slag about resistance to solutions corrosion
