那便是下围棋可“得天寿”的理论根据。
预过载拉伸可提高铝合金缺口疲劳寿命，但效果不及喷丸； 过载量太大还使寿寿命趋于子下降。
The experiments on notched specimens of an Aluminium alloy indicat that the notch fatigue life can be increased by a tensile over-pre loading but decreased by a compressive over-pre loading.
最后，选择万寿菊核不育两用系AALY001为材料，对雄性不育株和可育株进行扩增，得到了一条在不育株中缺失，在可育株中出现的稳定的特异标记NMSOPM09500。
Thirdly, using RAPD technique to amplify DNA of the AALY001 NMS two lines, one specific marker NMSOPM09500 was obtained in the male fertile line but without in the male sterile line.
