長方體內最少完全城堡數

我們試著尋找所需最小的城堡個數以看守整個a × b × c (a,b,c ? N) 的長方體。所謂城堡是一種棋子,當放置城堡的位置是(x, y, z) ,則(x, y,t)、(...

雪山姑 翡翠嫂 順姑情 逆嫂意? 雪山隧道之地質環評與工程建設的恩怨情仇

實驗初期以膠體水晶模擬岩層,模擬雪山隧道水平傾斜約 1°,製作壓克力模型(實驗一),證明是否如賈儀平教授所言《雪山隧道=水脈改道》註3,同時此模型也證明隧道防水襯墊完工後,和隧道開挖時水力梯度...

會逆轉的石頭-RattleBack 逆旋現象

具有長短兩軸的對稱性剛體,譬如半橢球,在施加適當質量配重後,給予其Z 軸方向的 初角速度,將會逐漸上下震盪、搖擺,而後改變原先的角速度方向,朝相反的方向逆轉回來。 此現象稱為「逆旋現象」,本研究分析關...
