As the revitalization of city culture and the city cultural confidence has been increasingly valued, the ancients' perception and interpretation of mountains, rivers and cultural landscapes, as well as their wisdom in the construction of traditional cities deserve more attention and further exploration. Taking ancient Yiyang City for example, this paper on the basis of local chronicles and literature analyzed the construction history of the city, famous mountains and rivers, and top eight views, and attempted to interpret the construction system of "mountain, river and city" landscape of traditional Chinese cities, in order to provide historical basis and cultural background for revitalizing local cultures and shaping urban landscape patterns, and offer spatial strategies for the city protection and renewal.

分别采用置换填充工艺(DCP)和热压烧结工艺(HP)制备了W/Zr C金属陶瓷,然后在2600℃下对其进行热处理1 h。研究了热处理前后2种W/ZrC金属陶瓷的组织结构变化。研究表明,热处理后2种材料都出现开孔率增大、线膨胀及质量损失。其中DCP法W/Zr C金属陶瓷在热处理后仍由分散分布的W颗粒相和连续的Zr C相组成,但原始材料中残留的WC、W_2C及Zr-Cu合金相都消失,取而代之的是大量的孔隙,同时W相含量也急剧减小。而HP法W/Zr C金属陶瓷在热处理后则有新相W_2C生成,同时其W颗粒相有聚集的趋势,形成了大块团状相。

The dominant annual cycle of sea surface temperature(SST)in the tropical Pacific exhibits an antisymmetric mode,which explains 83.4%total variance,and serves as a background of El Niño-Southern Oscillation(ENSO).However,there is no consensus yet on its anomalous impacts on the phase and amplitude of *** on data during 1982-2022,results show that anomalies of the antisymmetric mode can affect the evolution of ENSO on the interannual scale via Bjerknes feedback,in which the positive(negative)phase of the antisymmetric mode can strengthen El Niño(La Niña)in boreal winter via an earlier(delayed)seasonal cycle transition and larger(smaller)annual *** magnitude of the SST anomalies in the equatorial eastern Pacific can reach more than±0.3◦C,regulated by the changes in the antisymmetric mode based on random sensitivity *** reveal the spatial pattern of the annual cycle associated with the seasonal phase-locking of ENSO evolution and provide new insight into the impact of the annual cycle of background SST on ENSO,which possibly carries important implications for forecasting ENSO.
