質問: 英語の解釈をおねがいします。(物理) 物理分野の論文の一部ですが、どういう内容か知りたいんです。 難しいと思いますが、解釈できる方!どうかお願いします! 全体内容はこっちです。↓ http://www.dartmouth.edu/~etrnsfer/water.htm figure 1. the upper spectrum is that for liquid h2o in a 10 cm cell at room temperature; the lower spectrum is for d2o under the same conditions. no cell was used in the reference beam of the spectrophotometer so that the "baseline" absorbance of approximately 0.04 originates in cell reflections. the blue color of water may be easily seen with the naked eye by looking through a long tube filled with purified water. we used a 3 m long by 4 cm diameter length of aluminum tubing with a plexiglass window epoxied to one end of the tube. ten or more observers each reported seeing a blue color when they looked through the tube and observed a sunlight-illuminated white paper placed below the vertically-suspended tube (see for yourself in fig. on the right: h2o- on the left and blue, d2o-on the right and transparent). this observation is in accord with the spectrum of h2o recorded in fig. 1. for example, from the measured absorbance at 660 nm, the calculated transmission of a 3 m water-filled tube is 44% -- a loss of red intensity that should be perceptible. light transmitted through the empty cell was white. the large tube volume and a limited budget precluded checking to see if light transmitted through a d2o filled tube was indeed white, as expected.
回答: rabbit_cat さん、回答ありがとうございます 重水の価格、考えてもいませんでした! 長さ 3m、直径 4cm のアルミ管の体積は 3.14 x 2 x 2 x 300 = 3770ml その価格は 和光純薬株式会社 http://www.siyaku.com/uh/shs.do?dspcode=w01w0104-2684 100g 17500円、1kg 「見積り」となっており、 100g 17500円で計算すると、66万円です 工業用精製水 20l 945円 のうち 66l の価格 1781円 と比べ、すごい高いです ただ、今回の原文 http://www.dartmouth.edu/~etrnsfer/water.htm を読むと、その大きな tube 2本を用い、1本に精製水、 1本に重水を入れ、太陽光のもとで 10人以上の観察者が 観察し、精製水は青く、重水は透明であったと報告して おり、 「検証しており」「検証できなかった」のは合いません 左側が水、右側が重水です 水は青く、重水は透明です ↓
