Power Grid Development in 60 Years since the Foundation of P.R.C.

Foreword Since the foundation of P.R.C.,the China's power grid develops with a high rate.By now,grids in all provinces except Xinjiang,Tibet,Hainan and Taiwan are AC/DC interconnected together,forming the structure of power grid interconnection in the whole country.

Human Rights Connotations and Contemporary Values of Traditional Chinese People-Based Thinking

The time-honored traditional Chinese minben(people-based) thinking has rich implications for human rights. The concepts of min and minben are much in line with their contemporary counterparts of "human" and "people orientation". Upholding the belief of "people as the foundation of states", minben advocates the fundamental political status of the people, and requires leaders to implement "people-oriented" policies. Its encapsulation of the theoretical foundation and basic requirements for the protection of human rights enabled it to promote the protection of people’s livelihoods and civil rights in ancient China. Its sublimation in contemporary China has had, and will continue to have, a far-reaching impact on the development of human rights in China.

Closed-form solution of beam on Pasternak foundation under inclined dynamic load

The dynamic response of an infinite Euler–Bernoulli beam resting on Pasternak foundation under inclined harmonic line loads is developed in this study in a closed-form solution.The conventional Pasternak foundation is modeled by two parameters wherein the second parameter can account for the actual shearing effect of soils in the vertical direction.Thus,it is more realistic than the Winkler model,which only represents compressive soil resistance.However,the Pasternak model does not consider the tangential interaction between the bottom of the beam and the foundation;hence,the beam under inclined loads cannot be considered in the model.In this study,a series of horizontal springs is diverted to the face between the bottom of the beam and the foundation to address the limitation of the Pasternak model,which tends to disregard the tangential interaction between the beam and the foundation.The horizontal spring reaction is assumed to be proportional to the relative tangential displacement.The governing equation can be deduced by theory of elasticity and Newton’s laws,combined with the linearly elastic constitutive relation and the geometric equation of the beam body under small deformation condition.Double Fourier transformation is used to simplify the geometric equation into an algebraic equation,thereby conveniently obtaining the analytical solution in the frequency domain for the dynamic response of the beam.Double Fourier inverse transform and residue theorem are also adopted to derive the closed-form solution.The proposed solution is verified by comparing the degraded solution with the known results and comparing the analytical results with numerical results using ANSYS.Numerical computations of distinct cases are provided to investigate the effects of the angle of incidence and shear stiffness on the dynamic response of the beam.Results are realistic and can be used as reference for future engineering designs.
