《科技》東貝吳慶輝:台LED廠今年都賺錢
2013/06/22 16:49 時報資訊

【時報-台北電】東貝 (2499) 董事長吳慶輝昨(21)日指出,電視背光源今年LED滲透率上看9成、LED照明下半年需求大爆發,台灣相關LED廠今年一定都賺錢!

吳慶輝表示,LED電視背光滲透率今年達9成,但隨著尺寸變大、高解析度兩大趨勢來臨,預料電視背光至少還有2年的成長期。而LED照明的需求今年才剛開始,因此推估至少還有6至7年的高成長率。

吳慶輝指出,市場需求持續增溫,所以目前LED供過於求的問題終究會獲解決,尤其是對提供高規、進入門檻高產品的台灣LED廠今年算是走向大成長的時間點。(新聞來源:工商時報─記者楊曉芳/台北報導)

急~一個國二理化-壓力-的疑問..15點
Jun 23rd 2013, 01:42

http://img825.imageshack.us/img825/5180/5bl1.png

請見上圖(畫得沒有很精準請見諒..)
甲乙丙為三個底面積相同、形狀不同的容器,
如圖所示,各裝入等量的水,
三容器底面所受的水壓力,何者最小?

第一個疑問:

我是用公式 P = h x D(液體深度 x 液體密度)
他們的密度(水密度=1)跟液體深度都相等
所以他們受的壓力不是應該相等嗎?
但講義的解答是說丙最小...
難道是我觀念錯誤了嗎??..

第二個疑問:

還有一個題目跟我上面講義↑的一樣,只是他最後是問
三個容器底面所受的壓力關係
依這種題目來看的話壓力跟水壓力有差嗎??

快要段考了!!這個題目一直出現
但不知道到底哪個答案是正確的
請幫我解答吧!!
感激不盡!!
