论文部分内容阅读
Halide perovskites containing both or-ganic and inorganic cations are receiving extensive attention for their promising optoelectronic properties,including pho-toluminescence (PL) [1,2].Tuning these properties for specific applications and designing and synthesizing perovskites with optimized properties are major goals of materials science.

Classical cryptography has been around for a long time in the documented human history,but most classical ciphers were broken and even solved by hand.Shannon introduced the notion of perfect secrecy that formally defines confidentiality in the information

一必须在十五分钟里解决午餐,剩下四十五分钟去铁芬尼.钰苏在心里跟自己说.rn高跟鞋在酒店地下室通向员工餐厅的走廊上蹀踱蹀踱,一步紧一步的回响,自己听着都烦.rn二主卧的墙壁应该完工了,冬日的阳光透过落地窗大面积照射到房间,墙面的城市灰正从深往浅过渡,灰的底色上凸显出淡金色的菱形图案,有一种绸缎般的丝质效果.rn一年前,她把卧室最显眼的墙面上那幅三十寸的木雕框婚纱照取下,换成自己的一幅酥胸半裸的侧逆光肖像照,原本的家庭主卧瞬间就有了闺房的私密与任性.不过要彻底抹去一个男人留在房间里的气息,刷墙可能是最简捷有

The invention of public-key cryptography(PKC) by Diffie and Hellman in 1976 is one of two milestones marking the be-ginning of modern cryptography.The se-curity of a PKC system requires that it should be infeasible to compute the pri-vate key from a given

记得是上世纪八十年代,父亲的书房里曾经悬过一幅字,是他一生的老师、曾经的系主任朱东润先生的手书.那是苏轼的《赠孙莘老七绝》之一:rn嗟予与子久离群,耳冷心灰百不闻.rn若对青山谈世事,当须举白便浮君.rn朱先生写好这幅字后,就放进一个牛皮纸大信封,送到了当时我家住的复旦大学第四宿舍门房.那幅字写得好,父亲觉得一“那气势说高山苍松,说虬龙出海,都既无不可又不够贴切.”(潘旭澜《若对青山谈世事——怀念朱东润先生》)朱先生的字上没有写年月,但父亲的文章中说是1987年,因为父亲记忆力极佳,所以不会错.也许是想起
