The incidence of myopia has increased rapidly in recent decades, suggesting that environmental factors, such as light,may be an important cause. Correlated color temperature(CCT) is a commonly used index to quantify the spectral composition of light. Here, we used 32 juvenile monkeys(16 females and 16 males) and selected four kinds of light with typical but different CCTs to study the relationship between CCT and ocular axial elongation.

某新建立交桥多次跨越地铁盾构区间隧道,其桩基基础工程离盾构隧道结构较近,属于近接施工。在新建立交桩基施工过程中,由于钻孔扰动、施工荷载等因素会引起地层产生移动和变形,导致附存于地层中的区间隧道结构随之发生移动和变形。通过数值模拟,分析桥梁桩基施工对隧道结构的内力及位移影响,进一步对桥梁设计及施工方案进行优化,以减小近接施工的影响,规避一定量风险。通过数值模拟软件Midas/GTS计算得出的管片位移、盾构隧道拱顶最大沉降变形与径向收敛变形均未超过控制标准,其模拟计算结果与现场监测数据基本相符。

Aqueous Zn-ion batteries(AZIBs)have attracted increasing attention in next-generation energy storage systems due to their high safety and ***,the side reactions,dendrites and hydrogen evolution effects at the zinc anode interface in aqueous electrolytes seriously hinder the application of aqueous zinc-ion ***,we report a critical solvation strategy to achieve reversible zinc electrochemistry by introducing a small polar molecule acetonitrile to form a“catcher”to arrest active molecules(bound water molecules).The stable solvation structure of[Zn(H_(2)O)_(6)]^(2+)is capable of maintaining and completely inhibiting free water ***[Zn(H_(2)O)_(6)]^(2+)is partially desolvated in the Helmholtz outer layer,the separated active molecules will be arrested by the“catcher”formed by the strong hydrogen bond N-H bond,ensuring the stable desolvation of Zn^(2+).The Zn||Zn symmetric battery can stably cycle for 2250 h at 1 mAh cm^(-2),Zn||V_(6)O_(13) full battery achieved a capacity retention rate of 99.2%after 10,000 cycles at 10 A g^(-1).This paper proposes a novel critical solvation strategy that paves the route for the construction of high-performance AZIBs.
