convex lens 中文意思是什麼
convex lens
解釋
凸透鏡。-
Just as a double convex lens enlarges, so a double concave lens reduces
正象雙凸透鏡可以放大那樣，雙凹透鏡也可以縮小。 -
We fabricated a large computer - generated holography on a concave lens surface to test the convex secondary mirrors surface
在凹透鏡表面上製作出了用於凸非球面檢測的曲面全息圖。 -
However, spectacles are made of thick convex lens. skills and precautions are needed to wear contact lens properly. both are not suitable for the elderly
不過，這些眼鏡片有相當的厚度，配戴隱形眼鏡亦需要一些特別技巧，對于年紀較大的患者未必適合。 -
Since lenticular clouds look like one or more convex lens, they could sometimes be misinterpreted as flying saucers or unidentified flying objects, and so they are commonly known as " flying saucer clouds "
由於這類莢狀雲形狀像一塊或多塊凸透鏡，有時候被誤會為飛碟或不明飛行物體，所以亦俗稱飛碟雲。 -
Analysis showed this might be due to the fact that a black hole passed in front of the star. the gravitation of a black hole can function as a convex lens and focus starlight, resulting in transience increase of apparent brightness of the star
分析顯示，這很可能是因為有一個黑洞在恆星前面經過，黑洞的引力會聚了星光，就像凸透鏡把光線聚焦一樣，使恆星的視亮度增加。 -
The gravitation field of star b bends the light from star a as a convex lens does and we can observe a sudden brightening of star a. much brighter than the total brightness of star a and b. this phenomenon is called microlensing
根據國際天文學聯會international astronomical union於2006年8月24日通過的行星定義，冥王星的行星資格被取消，並被界定為一類稱為矮行星的新天體。 -
Surrounding with the subject of minor asphere making and test, we pursued work in four side : the design, test and making of aspheric indirect ophthalmoscopy lenses, test and making of aspheric ge lens, double asphere lens testing, study on testing of refractive convex aspheric surface
本文圍繞小型非球面檢驗加工這個課題，主要做了四個方面的工作：非球面眼底鏡的設計、加工和檢驗，非球面鍺透鏡的加工檢驗，雙面非球面小型透鏡檢驗方法的探討，凸二次非球面檢驗方法的研究。
