查询词典 light source

This model considers the flow of energy between two regions around the black hole : an inner region that is close to the so--called event horizen (the boundary beyond which even light cannot escape ), and an outer region that includes the black hole's fuel source-- the young stars--extending up to a million times father out .

此模型分析围绕在黑洞周边的两个区域间的能量流：内部的区域接近于视界（一个理论上的边界，超过此边界甚至光都无法逃脱黑洞的吞噬），外部区域包括黑洞的燃料源——年青的恒星——并继续扩展数百万倍。

In his Culture and Anarchy , Matthew Arnold writes,"The great men of culture are those who have had a passion for diffusing, for making prevail, for carrying from one end of society to the other, the best knowledge, the best ideas of their time; who have laboured to divest knowledge of all that was harsh, uncouth, difficult, abstract, professional, exclusive; to humanise it, to make it efficient outside the clique of the cultivated and learned, yet still remaining the best knowledge and thought of the time, and a true source, therefore, of sweetness and light."

马修·阿诺德在《文化和无政府状态》一书中这样描述："伟大的文化人是这样一些人，他们具有一种激情，要将他们时代最好的知识、最好的思想从社会的一端传播和搬运到社会的另一端，使之流行不衰；他们殚精竭虑，要为知识去除一切粗糙的、粗野的、难解的、抽象的、专业的和孤傲的成分，要把它人性化，使它在绅士和学者的圈子之外，也见成效，与此同时，又保留了时代最好的知识和思想，因而成为甜美和光明的真正源泉。"
