A nickel hexacyanoferrate(NiHCF)film electrode was prepared with NiHCF,conductive carbon black,and polyvinylidene difluoride,which was coated on graphite plate substrate for selective extraction of Cs^(+)ions by using electrochemically switched ion exchange(ESIX)technology.A potential-responsive ionpump system for efficient extraction of Cs+ions was designed,and the effect of wet film thicknesses,charging modes,flow rates,and chamber widths on Cs+ions extraction performance was *** the system,the adsorption capacity and removal percentage of Cs^(+)ions on the NiHCF film electrode reached as high as 147.69 mg·g^(-1)and 92.47%,***,the NiHCF film electrode showed high selectivity for Cs^(+)ions and *** seven cycles of adsorption/desorption,the desorption percentage could reach about 100%.The excellent Cs^(+)extraction performance should be attributed to the strong driving force produced by the potential-responsive ion-pumping effect in the ESIX process,as well as the low ion transfer resistance of the film electrode which is caused by the special crystal structure of *** addition,the NiHCF film electrode was implemented to work together with the bismuth oxybromide(BiOBr)film electrode to accomplish the simultaneous extraction of Cs^(+)and Br^(-).And the adsorption capacity and removal percentage of Br^(-)ions on the BiOBr film electrode reached 69.53 mg·g^(-1)and 77.32%,*** is expected that such a potential-responsive ion-pump system based on NiHCF and BiOBr film electrodes could be used for the selective extraction and concentration of Cs^(+)and Br^(-)ions from salt lake brine.

Based on China’s real estate investment(REI), commercial housing sales(CHS), and GDP data from 2001 to 2020, we studied the dependence, asymmetry, and transmission direction of China’s real estate and economy. Their cross-correlation is demonstrated through the deep crosscorrelation analysis(DCCA) algorithm, multifractal asymmetric detrended cross-correlation analysis(MF-ADCCA) algorithm and DCCA algorithm based on a time delay. Both REI and CHS have persistence with GDP. The real estate industry and economy have asymmetric multifractal ***, real estate and the economy have different trends, and they can affect each other with the same length of time delay. This effect diminishes in a short period of time, and there are unsteady fluctuations in cross-correlation persistence in the long term.

维吉尔的史诗《埃涅阿斯纪》最后30余行,描写主人公埃涅阿斯在盛怒之下,不顾图尔努斯的祈求,将其杀死。以"哈佛派"为代表的现代解读,批评主人公未能抑制愤怒。但其他学者在亚里士多德和伊壁鸠鲁主义哲学中找到相关论述,证明埃涅阿斯之怒是正当之举。这场持续已久的争论,显示了文学解读和情感哲学之间的复杂关系。

圣经古拉丁文译本因为种种原因,语言粗鄙,经常遭人诟病。早期基督教作家对此并不讳言,但却认为此种鄙俗的文体远胜过古典作家华丽的词藻,并由此发展出一套辩护的策略,将修辞学的问题上升为宗教思想的论争。在奥古斯丁等人看来,古典作家思想贫乏,不过以华美的辞章掩盖空洞的内容,而基督教不仅带来思想革命,也带来修辞学方面的改进。圣经这种平易、简朴、鄙俚的语言符合"道成肉身"的教义,使得寻常百姓、贩夫走卒也能体悟基督教的道理。对圣经文体的辩护相当于对古典修辞学传统进行了一次"价值重估"。
