This paper studies the properties of relaxation and diffusion of energy, heat, momentum, and mass density fluctuations in a one-dimensional Toda-like lattice model at finite temperature, and discusses their relationship to the thermal conductance of the system. It is found that the interatomic potential function of this kind of lattice shows the Toda potential at low temperature, and that consequently the class of lattice appears the behavior of the integrable Toda lattice, such as diffusion tending to ballistic and heat conduction not satisfying the Fourier law, which lead to abnormal diffusion and heat conduction. The asymmetry of the potential function and the nonintegrability are rapidly enhanced with the temperature increased, thus the fluctuation of heat and energy density exhibit normal diffusion characteristics in a large temperature range. This result shows that the asymmetric interaction can lead to normal diffusion behavior in a one-dimensional momentum-conserving lattice, and the finding provides a micro-mechanism support to the phenomena that this class of system presents normal heat conduction.

An index model of relationship between built-up urban area and urban population is established and it reveals the long-term equilibrium relationship of population urbanization and land urbanization. The empirical test on 12 western provinces show that long-term land scale elastic coefficient is 1.48 (the reasonable international value is 1.12), which implies the imbalanced development between population urbanization and land urbanization, either back-warded population urbanization or advanced land urbanization. To be specific, results vary from a province to another: Chongqing and Ningxia score the highest, about twice the standard; in Gansu and Qinghai, the land scale elasticity coefficient is lower than the standard values; other provinces are in between. Based on the result, corresponding countermeasures and suggestions are put forward.

In late Qing Dynasty, the Trivia Games, a column in Tapestry Portrait Novel, published many articles from natural science to humanities and society with an attempt to open people's eyesight so as to achieve the ultimate goal of enlightenment. Some of its content was not reasonable but very attractive since it aimed to make itself scientific as well as interesting, which seemed embarrassingly like the chicken ribs, things of little value and interest. As the editorial thoughts changed, the column was eventually canceled. However, it can never be denied that the column was a bold attempt of westernized Chinese style, and men and women with high ideals of that time made a great endeavor to enlighten the people and to promote social progress by means of trivia games.
