進一步分為四級(0-1罐、2-4罐、5-7罐、14罐或以上)所得到的結果相當明顯,隨著過去一週喝汽水的量越多,出現暴力行為以及攜帶刀槍的比例也隨之上昇。如果把每週喝0-1罐汽水的孩子,跟每週喝14罐或以上的孩子相比,每週喝14罐或以上的汽水的孩子,過去一年曾攜帶刀槍的比例高出20%(43% vs. 23%),過去一年曾有暴力行為的高出12%(27% vs. 15%);其中對同學或朋友施暴的比例高出23%(58% vs. 35%),對兄弟姊妹施暴的比例高出18%(43% vs. 25.4%)。
以市面上備受矚目的 Panasonic A La Uno 全自動洗淨馬桶為例,就是將材料科學、結構工程與流體力學發揮到極致的典型代表:
1. 材料層:有機玻璃系新素材
A La Uno 全自動洗淨馬桶採新開發的「有機玻璃系新素材」(以壓克力高分子為基礎研發的衛浴專用材料,這類高分子成形技術亦被廣泛運用於大型水族館高壓觀景窗與飛機機艙罩)。這種材料表面具備極佳的疏水性與耐水垢特性,水滴不易長時間攤平停留;材質堅固、不易破裂,耐刮、不易造成細小傷痕。通過實驗測試,這種素材配合泡沫洗淨,在沖洗後能有效沖刷掉高達 99.99% 的大腸桿菌,從源頭阻斷細菌定殖。

2. 結構層:無接縫工藝與三重防濺防護
在宏觀結構上,A La Uno 全自動洗淨馬桶採用無水箱沖水與便器、溫水洗淨便座一體成型設計,減少傳統水箱與座體之間的結構層次及接縫,並搭配可動迴轉式排水系統完成沖洗。更貼心的是其「三重防護」設計:
泡沫防護:在水面上製造一層充沛的泡沫緩衝層,有效抑制男性站立小便時的尿液與污水飛濺;
外圍防護:馬桶邊界特別設計了高約 3mm 的水檔,防止液體延著外壁滴落至地板;
測漏防護:便座與馬桶本體採用不外露的防護設計,避免液體從縫隙飛濺滲漏。

3. 動態流體層:雙效泡沫洗淨、漩渦水流與 nanoe™ X
當污垢降落在馬桶內壁時,A La Uno全自動洗淨馬桶 的動態流體科技便接手進行徹底打掃。其「雙效泡沫洗淨」會先釋放直徑約 5mm 的「毫米泡沫」包裹並帶走大塊髒污,再透過直徑約 60微米的「微米泡沫」深入微觀縫隙,徹底溶解殘餘的油脂與細微污垢。接著,配合高度清潔力的「漩渦型強力水流」,利用旋轉產生的流體剪切力,一口氣將附著力已被削弱的污垢剝離並沖走。此外,Panasonic A La Uno 全自動洗淨馬桶還搭襯了 nanoe™ X 健康科技,釋放氫氧離子有效抑制異味與髒污,維持空氣與內壁的良好衛生狀態。
在一對染色體中相對位置上的基因,就像並排的兩列火車,A 火車第三節車廂與 B 火車第三節車廂位置是一樣的,他們之間的關係也是決定基因表現的原因之一。這兩個基因便是大家聽過「等位基因」。它們造成的結果一如生物課本上大家都看過的例子:只考慮遺傳因素的情況下,若紅花是顯性基因,白花是隱性基因,且這個性狀是半顯性遺傳,那同時有顯性跟隱性基因的植物就會開出粉紅色的花。
