S-N approach is used for prediction of the components subjected to high cycle fatigue, where the materials are within elastic limit.
Differences of cycle life between these two materials were reported with Goodman, Gerber and interpolate mean stress correction method.

Therefore, bamboo decay fungi can obtain nutrients through the degradation of cellulose, hemicellulose or even lignin, and some other materials with cell wall, so that the bamboo cells are destroyed and the mechanical strength is reduced or even completely loses use value.
Under proper temperature and humidity, spore will germinate the mycelium which produces single cell, the mycelium invades the bamboo timber to absorb sugars, starch and some other raw materials of bamboo cell, and then it grows on the bamboo[1].
Sun Fangli, etc. [11] apply the newly cut Phyllostachys pubescensas of 3 to 4 years old as test materials, Penicillium, Trichoderma and Aspergillus niger are the test bacteria, comparing with the commonly used HBO3 and chlorothalonil, the anti-mold performance of the CCC and CZC of CMC is tested.
This method is expected to be the new method of improving bamboo performance, and it also has reference meaning to the protection and improvement of other natural raw materials besides wood.
