无论新钢琴或是旧钢琴的机械性能,都会在不同时期、不同的环境条件下,产生不同程度的变化,且多以触感不良、音准失调等形式表现出来。产生这些毛病的原因很多,除钢琴本身工艺质量差或人为的损伤外,很重要的一条要数钢琴对环境条件的敏感性了。我国疆域辽阔,地理和气候条件复杂,东西南北相差悬殊(南方的海南岛等地区最热月最大相对湿度达95％,而黄河河套地区最小相对湿度仅为5％),钢琴受环境温湿
Regardless of the mechanical performance of a new piano or an old piano, it will change in varying degrees and under different environmental conditions in different periods, and more often will be manifested in the form of poor touch and quasi-mismatch. There are many reasons for these problems, in addition to the piano itself poor quality or man-made damage, it is important to the number of piano sensitivity to environmental conditions. China’s vast territory, geographical and climatic conditions are complex, great differences between east and west, north-south (the hottest month in southern Hainan and other regions the maximum relative humidity of 95%, while the Yellow River Loop area minimum relative humidity of only 5%), the piano by the ambient temperature and humidity
