最新笔记本电脑维护便利度排名显示，华硕连续三年保持领先地位，而苹果则持续垫底。分析指出，苹果得分偏低主要源于其设备内部构造与固定方式导致拆解异常困难，大幅提升了第三方维修与用户自行维护的成本。此外，苹果、戴尔与三星因同时参与两个行业协会，被额外扣除1分。联想以接近不及格的成绩位列倒数第二，其拆解评分同样不尽如人意。

The loss curves make the divergence between Sigmoid and ReLU very clear. Both networks start from the same initialization and are trained under identical conditions, yet their learning trajectories quickly separate. Sigmoid improves initially but plateaus around ~0.28 by epoch 400, showing almost no progress afterward — a sign that the network has exhausted the useful signal it can extract.
