2024年12月21日，根据清代史料，若以普通速度，驿递需时约30至35天；若以“四百里加急”，需时约20多天；若以“五百里加急”，需时约16至19天。如果是“六百里加急”“八百里加急”，速度当然更快，大约10天左右，那样会跑死驿马、累死驿卒，除非军情紧急，一般不采用。

We used the Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) instrument to perform deep ultraviolet Raman and fluorescence spectroscopy of three rocks within the crater. We identify evidence for two distinct ancient aqueous environments at different times. Reactions with liquid water formed carbonates in an olivine-rich igneous rock. A sulfate-perchlorate mixture is present in the rocks, probably formed by later modifications of the rocks by brine. Fluorescence signatures consistent with aromatic organic compounds occur throughout these rocks, preserved in minerals related to both aqueous environments.wulixuePhysicsGiant electric field–induced strain in lead-free piezoceramicswuqianyadiantaocizhongdejudachangzhiyingbian▲ zuozhe：GENG HUANGFU, KUN ZENG, BINQUAN WANG, JIE WANG, ZHENGQIAN FU, FANGFANG XU, ET AL.▲ lianjie：https://www.science.org/doi/10.1126/science.ade2964▲ zhaiyao：yadianzhidongqiyiqikuaisuxiangyinghejingqueweiyizaixuduoxingyezhongdubukehuoque。daduoshushangyongyadianzhidongqihanyouqian，duihuanjinggouchengliaoweixie。yanjiuzutongguochangguiguxiangfanyingfahechengliaowuxurenhehouchulidezuo（Sr）chanza(K,Na)NbO3wuqianyadiantaoci，huodeliaojudayingbian（1.05%）hedaxinhaodeyadianyingbianxishu（2100 pm/V）。chanshengchaogaodianyingbiandejibenjizhishiquexianoujizihechouqiehuanzhijiandexianghuzuoyong。gaiwuqianyadiantaocizai20 kV/cmxiadekangpilaoxingneng、rewendingxingheyingbianzhi（0.25%）keyushangyongPb(Zr,Ti)O3jitaocixiangzuomeishenzhigengyou，xianshichujudadeshijiyingyongqianli。gaicailiaoyouwangweiyadianzhidongqitigongyizhongjiandanzuchengdewuqiantidaipin，bingweigaoxingnengyadianshejitigongyigefanli。▲ Abstract：Piezoelectric actuators are indispensable over a wide range of industries for their fast response and precise displacement. Most commercial piezoelectric actuators contain lead, posing environmental challenges. We show that a giant strain (1.05%) and a large-signal piezoelectric strain coefficient (2100 picometer/volt) are achieved in strontium (Sr)–doped (K,Na)NbO3 lead-free piezoceramics, being synthesized by the conventional solid-state reaction method without any post treatment. The underlying mechanism responsible for the ultrahigh electrostrain is the interaction between defect dipoles and domain switching. The fatigue resistance, thermal stability, and strain value (0.25%) at 20 kilovolt/centimeter are comparable with or better than those of commercial Pb(Zr,Ti)O3-based ceramics, showing great potential for practical applications. This material may provide a lead-free alternative with a simple composition for piezoelectric actuators and a paradigm for the design of high-performance piezoelectrics.xinxikexueInformation ScienceCompetition-level code generation with AlphaCodeAlphaCodejingsaijibiedaimashengcheng▲ zuozhe：YUJIA LI, DAVID CHOI, JUNYOUNG CHUNG, NATE KUSHMAN, JULIAN SCHRITTWIESER, R?MI LEBLOND, ET AL.▲ lianjie：https://www.science.org/doi/10.1126/science.abq1158▲ zhaiyao：bianchengshiyizhongqiangdaerpubiandejiejuewentidegongju。nenggoubangzhuchengxuyuanshenzhizijishengchengchengxudexitongkeyishibianchenggenggaoxiao、gengyifangwen。zuijinjiyuzhuanhuanqideshenjingwangluomoxingxianshichulingrenjingyandedaimashengchengnengli，danzaixuyaojiejuewentijinengdegengfuzarenwu（rujingzhengxingbianchengwenti）shangrengbiaoxianbujia。yanjiuzujieshaoliaoAlphaCode，zheshiyigeyongyudaimashengchengdexitong，zaiCodeforcespingtaishangzuijindebianchengjingsaimonipingguzhongpingjunpaimingqian54.3%。AlphaCodetongguoshiyongjingguozhuanmenxunlian、jiyuzhuanhuanqidewangluoshengchengshubaiwangebutongchengxu，ranhouduizhexiechengxujinxingguolvhejulei，zuiduozhitijiao10ge，congergaoxiaojiejuewenti。gaijieguobiaozhizhuorengongzhinengxitongshoucizaibianchengjingsaizhongbiaoxianchuse。▲ Abstract：Programming is a powerful and ubiquitous problem-solving tool. Systems that can assist programmers or even generate programs themselves could make programming more productive and accessible. Recent transformer-based neural network models show impressive code generation abilities yet still perform poorly on more complex tasks requiring problem-solving skills, such as competitive programming problems. Here, we introduce AlphaCode, a system for code generation that achieved an average ranking in the top 54.3% in simulated evaluations on recent programming competitions on the Codeforces platform. AlphaCode solves problems by generating millions of diverse programs using specially trained transformer-based networks and then filtering and clustering those programs to a maximum of just 10 submissions. This result marks the first time an artificial intelligence system has performed competitively in programming competitions.cailiaokexueMaterials ScienceLiquid metal synthesis solvents for metallic crystalszaiyetaijinshurongjizhonghechengjinshujingti▲ zuozhe：SHUHADA A.

We show an analogy of this when zinc (Zn) dissolves and crystallizes in liquid gallium (Ga). The low-melting-temperature Ga is used as a “metallic solvent” to synthesize a range of flake-like Zn crystals. We extract these metallic crystals from the liquid metal solvent by reducing its surface tension using a combination of electrocapillary modulation and vacuum filtration. The liquid metal–grown crystals feature high morphological diversity and persistent symmetry. The concept is expanded to other single and binary metal solutes and Ga-based solvents, with the growth mechanisms elucidated through ab initio simulation of interfacial stability. This strategy offers general routes for creating highly crystalline, shape-controlled metallic or multimetallic fine structures from liquid metal solvents.Designing better electrolytesshejigenghaodedianjiezhi▲ zuozhe：Y.

Designing better electrolytes and interphases holds the key to the success of these batteries. As the only component that interfaces with every other component in the device, an electrolyte must satisfy multiple criteria simultaneously. These include transporting ions while insulating electrons between the electrodes and maintaining stability against electrodes of extreme chemical natures: the strongly oxidative cathode and the strongly reductive anode. In most advanced batteries, the two electrodes operate at potentials far beyond the thermodynamic stability limits of electrolytes, so the stability therein has to be realized kinetically through an interphase formed from the sacrificial reactions between electrolyte and electrodes.huaxueChemistryCatalytic asymmetric C–H insertion reactions of vinyl carbocationsyixijitanzhenglizidecuihuabuduichengC-Hcharufanying▲ zuozhe：SEPAND K.

Although these reactive intermediates are engaged in stereoselective processes in nature, exerting enantiocontrol over carbocations with synthetic catalysts remains challenging. Many resonance-stabilized tricoordinated carbocations, such as iminium and oxocarbenium ions, have been applied in catalytic enantioselective reactions. However, their dicoordinated counterparts (aryl and vinyl carbocations) have not, despite their emerging utility in chemical synthesis. We report the discovery of a highly enantioselective vinyl carbocation carbon–hydrogen (C–H) insertion reaction enabled by imidodiphosphorimidate organocatalysts. Active site confinement featured in this catalyst class not only enables effective enantiocontrol but also expands the scope of vinyl cation C–H insertion chemistry, which broadens the utility of this transition metal–free C(sp3)–H functionalization platform.
