最近DJ推薦的問題”無霜冰箱的原理”引出了不少爭論,幾個重要的爭議為;(1). 冰塊有沒有昇華現象? (2) 無霜冰箱冷凍庫內是否真的不結霜,還是有自動加熱除霜裝置? (3). 無霜冰箱風扇的作用不明. 畢竟科學是需要實驗證明的,在此藉下面一則實驗挑戰正反兩方的論點:用保力龍餐杯結出大小相同的冰塊兩塊,一塊放進密封塑膠袋或加蓋透明塑膠盒,另一塊放在小碟子上.然後放進冷凍庫裡,離門稍微遠一點,觀察一個禮拜後紀錄冰塊體積和形狀的變化,然後用你的論點來解釋觀察到的現象.如果保力龍餐杯不好用,其他塑膠杯也可以.這只是拋磚引玉.網友如有更好的想法,歡迎指教.

我某天看到以下這篇文章:

環保署積極推動資源回收工作,要求各縣市環保局結合各項宣導活動進行資源回收,台北縣政府將結合「2006鶯歌國際陶瓷嘉年華」活動,辦理廢乾電池回收宣導,提供3號鹼性乾電池給民眾直接兌換,並提供新台幣5000元等多種不同金額禮券給民眾回收廢乾電池後兌換抽獎券,以參加10月29日之抽獎活動,只要民眾回收廢乾電池,即有機會抽中5000元禮券。

環保署指出,目前市售乾電池的種類繁多,因乾電池含有汞、鎘及鉛等重金屬成分,若民眾使用後的廢乾電池未妥善回收而任意棄置,則電池中有毒的重金屬物質將累積在環境生態中,滲透於土壤、污染地下水,進而進入魚類、農作物中,最後再透過食物鏈進入人體,將對民眾的健康造成影響。

環保署表示,目前各縣市政府正積極配合該署推動資源回收政策,並舉辦一系列的相關活動,例如:雲林縣環保局提供霹靂布袋戲人偶磁鐵給民眾回收廢乾電池直接兌換;新竹市環保局提供筆記型電腦、液晶電視及數位相機等多項大獎給民眾回收廢乾電池兌換抽獎券,可分別參加本年9月及12月底的2次抽獎活動。而台北縣政府環保局亦將結合「2006鶯歌國際陶瓷嘉年華」活動,提供3號鹼性乾電池及新台幣5000元等多種不同金額禮券,自即日起,民眾每回收10個廢乾電池,即可於活動現場(鶯歌鎮文化路200號陶瓷博物館左側林蔭大道)直接兌換3號鹼性乾電池1個及抽獎券1張,凡持有抽獎券者將可參加本月29日下午3時於「2006鶯歌國際陶瓷嘉年華」主舞台前的禮券公開抽獎活動。相關活動辦法可洽台北縣政府環保局,電話:(02)29603456。民眾如有其他廢乾電池回收相關問題,亦可電洽環保署免付費資源回收專線0800-085717(您幫我,清一清)或至該署資源回收網查詢(http://recycle.epa.gov.tw)。


我想問 
第1.哪裡可以回收廢電池?
第2.拿給資源回收車,他會給你直接兌換3號鹼性電池嗎?
第3.自即日起,民眾每回收10個廢乾電池,即可於活動現場(鶯歌鎮文化路200號陶瓷博物館左側林蔭大道)直接兌換3號鹼性乾電池1個及抽獎券1張
他的意思是說~只能直接拿到活動現場才有可以兌換以及抽獎券嗎?

The practical applicability of the method was assessed by the analysis of 30 samples.
分析30個樣品來評估這個方法的實用性

Retinol contents ranged from 0.9 to 1.6 mg/100 g of dry mass,α-tocopherol contents from 26.2 to 49.0 mg/100 g of dry mass, and cholesterol contents from 2416.8 to 4203.6 mg/100 g of dry mass.
維生素A從0.9 to 1.6 mg/100 g of dry mass,維生素E從26.2 to 49.0 mg/100 g of dry mass,以及膽固醇從2416.8 to 4203.6 mg/100 g of dry mass.

The α-tocopherol and cholesterol higher values were obtained because the hepatopancreas is the main lipid storage organ from shrimp .
這維生素E和膽固醇公認為高價值的,因為胰肝腺是蝦類動物脂質重要的保存器官

To establish the optimal condition of lactic acid fermentation of shrimp waste, the study team carried out several sets of experiments and the obtained lipid fractions were analyzed for retinol,α-tocopherol, and cholesterol.
建立廢棄蝦類最佳的乳酸發酵條件,這研究完成實驗中獲得脂質部分並將其分析出維生素A、維生素E及膽固醇

Therefore, the variability cannot be attributed to analytical errors because all values are means of triplicate analysis.
因此,這變異性不能歸因於分析的錯誤,因為全部的標準是三成份的平均

However, after considering the nutritional composition, geographical location, and species of shrimp, the differences in data can be explained.
然而,之後考慮營養的組成、地理位置、蝦的種類,這報告無法解釋其差異

Determination of detection limits on the basis of signalto-noise ratio (3:1) as per American Chemical Society guidelines, which are smaller than those presented in other works, were 38 ng/ml for retinol, 80 ng/ml forα-tocopherol, and 1.38ug/ml for cholesterol.

Accuracy was estimated by means of recovery assays.
估計準確性用重複分析的方法

Three spiking levels were assayed in triplicate: 14.0, 26.4, and 31.3 ug/g for retinol, 85.1, 270.7, and 448.8ug/g forα-tocopherol, and 6600, 19800, and 33000ug/g for cholesterol.
三個成分分析:14.0, 26.4, and 31.3 ug/g for retinol, 85.1, 270.7, and 448.8ug/g forα-tocopherol, and 6600, 19800, and 33000ug/g for cholesterol.

The samples were subjected to the entire extraction and determination process.
這樣品全部萃取測定

Table 3 shows the overall recovery percentages obtained.
表3顯示全部獲得的百分比

Comparing these results with similar works is of no value, since this is the initial study of this process on lipid fraction from shrimp waste hydrolysate.

1)The atmospheric pressure on the Earth is due to the weight of the air molecules in the Earths atmosphere. Suppose a planet P has the same features as the Earth except that it has a (thinner) atmosphere than Earth, i.e. there is less air molecules in this planets atmosphere. Compare the value of the atmospheric pressure on the surface of the planet P to that on the surface of Earth. Explain your answer briefly.
