首先两种木地板都属于有槽口的木地板范围里，有槽口的木地板有一个共同的优势，木地板本身可以预留出伸缩缝隙，这样木地板即使受了外界环境影响导致地板之间伸缩挤压，也不回影响木地板的美观度。
Firstly, both kinds of wood floors belong to the range of wood floors with slots. Wood floors with slots have a common advantage. Wood floors themselves can reserve expansion slots, so that even if the wood floors are affected by the external environment, the expansion and extrusion between the floors will not affect the beauty of the wood floors.
首先V型槽地板连接的更加稳定。V型槽地板采用的是二次倒角，所以连接时比较稳定，而U型槽是一次模压成型，所以连接稳定性较差。
First, the V groove floor connection is more stable. V-groove floor is a secondary chamfer, so the connection is more stable, and U-groove is a one-time molding, so the connection stability is poor.
其次V型槽木地板可以避免拼缝处膨胀凸起，因而不用担心出现白边、起翘的现象。而U型槽却比V型槽更宽、更平整，这样不会形成灰尘死角，对于日后的保养和清洁带来方便。
Secondly, the V-grooved wood floor can avoid bulging at the joints, so there is no need to worry about white edges, warping phenomenon. The U-shaped groove is wider and smoother than the V-shaped groove, so it will not form a dead angle of dust, which will bring convenience for future maintenance and cleaning.
