visible substance 中文意思是什麼
visible substance
解釋
肉眼可見物-
Structured with glass or plastic transparant pipe, and directly make it into thermotube, which makes the whole thermotube become visible for our naked eyes to observe the work state of the working substance in the interior of thermotube ; fully transparent thermotube research and tutorial appliance also offers the metal and nonmetallic pipes of the same shape used for contrasting, from which we can conclude their diathermancy in different conditions, demonstrate intuitionistically and testing the different performances of the thermotube, which makes the study and the testing about the thermotube ' s performance more deep and easy
採用玻璃或透明塑料的管，並直接將其製造為熱管使得熱管的全部都是可以用肉眼觀測到熱管內部的工作介質工作的狀態，全透明熱管科研教學器具還給出了與熱管同樣外形的用於作對比的金屬管和或非金屬管，可以通過對比確定不同條件下的熱管與金屬或非金屬的傳熱性能，可以直觀的演示、測試熱管的各種性能，更深入、易懂地學習、試驗熱管的各種性能。 -
All data indicated that f i was a pure substance. third, using modern analytic techniques such as nucleic magnetic resonance ( nmr ), infrared spectroscopy ( ir ), ultraviolet visible absorption spectra ( uv ) and mass spectrometry ( ms ), we analyzed the basic chemical structure of f i and nominated it phthalic acid di ( 3 - methyl ) nanyl ester ( pdne ). we estimated primarily it was a novel natural compound
第三，利用核磁共振，紅外光譜，紫外分析，質譜等現代分析測試技術對分離提取物f進行結構鑒定，解析出f的結構，初步推斷該物質為鄰苯二甲酸- （ 3 -甲基）壬酯（ pdne ） ，根據目前所掌握的資料，還沒有檢索到該物質相關的報道，初步認定為一種新型的天然產物。 -
It could also cast light on the mystery ofdark matter, a substance that pervades the universe in vastly larger quantitiesthan familiar, visible matter, but whose existence can be inferred only bywatching its gravitational effect on visible matter
此設備同樣也能夠指引人們解開暗物質的神秘性；這種物質遍及整個宇宙且數量驚人，可它使一種難以被發現並極其陌生的物質，它的存在只能通過觀察它在可見物質上的重力反應來推測。
