We present a lattice quantum chromodynamics(QCD)simulation with 2+1+1 flavor full QCD ensembles using near-physical quark masses and different spatial sizes L,at a~0.055 *** results show that the scalar and pesudoscalar 2-point correlator with a valence pion mass of approximately 230 MeV become degenerated at L≤1.0 fm,and such an observation suggests that the spontaneous chiral symmetry breaking disappears effectively at this *** the same time,the mass gap between the nucleon and pion masses remains larger thanΛQCDin the entire L∈[0.2,0.7]fm range.

With the global ban on plastics intensifying, the substitution of plastic with paper has garnered increasing attention. However, the inadequate water and oil repellency of pulp molding hinders its practical applications. Currently, the common method to enhance the oil and water repellency of pulp molding is by adding fluorinated water and oil repellents. Nevertheless, fluorinated compounds are environmentally and physiologically harmful. Therefore, the development of fluorine-free, water and oil repellent alternatives is crucial. In this study, chitosan and stearic acid were utilized as the first and second layers of the oil and water repellent coatings, respectively. The coated samples exhibited favorable water repellency, with a water contact angle of 116.4°, and excellent oil repellency, achieving a 12/12 rating on the kit scale. Importantly, the samples did not exhibit any leakage after being soaked in hot water and hot oil at 95±5℃ for 30 min, demonstrating remarkable performance as a barrier against hot water and oil. Moreover, the coated samples displayed outstanding mechanical properties, thermal stability, biodegradability, and recyclability. The approach presented in this study is simple, cost-effective, environmentally friendly, and represents a promising technique for producing fluoride-free, oil-and water-resistant pulp molding products.

"天人合一"作为一个基本的哲学命题,其思维形态可以理解为多个阶段的动态过程,汉代恰好处在一个动态升华的关键时期。汉代开始,神本思想渐褪,对人的关注致使"天人合一"思想偏向于反映人的能动作用,尤其是儒家从"人"到"仁"思想的超越,直接成为"天人合一"理论走向深入的驱动力。"天人合一"中的"天"虽有中国哲学的本体地位,却又是为政治服务的"人为之天",是神学思潮影响下"天人合一"转型的产物。从对人关注的层面上,"天人合一"应为"人天合一",如此才易于理解汉代儒学的没落与兴盛、天人合一与天人相分、服务统治者与服务民众等争议话题的矛盾与统一之症结。
