Imbalanced Alfvénic turbulence is a universal process playing a crucial role in energy transfer in space, astrophysical, and laboratory plasmas. A fundamental and long-lasting question about the imbalanced Alfvénic turbulence is how and through w
Therefore, the plant operation happens by means of three cycles in a sequence: a closed thermodynamic cycle of the existing power plant (for instance, a water vapor Rankine cycle), an intermediate ammonia-closed Rankine cycle, and the open Rankine cycle for the natural gas direct expansion. By...
We issued agricultural supply subsidies to grain growers in three installments. All this helped ensure good grain harvests and stable supplies of major agricultural products. We leveraged the role of coal as a major source of energy, increased advanced coal production capacity and stepped up support...
The Four Stages of Globalization (1):在变局之下,中国企业的全球化主要受到以下三个关键因素的推动 Under the changing circumstances, the globalization of Chinese enterprises is mainly driven by the following three key factors: 1:企业自身发展壮大的原动力:中国企业自身的发展壮大成为推动其全球拓展的内生动力...
(1) The industrial structure effect: The existing research mainly expounds on the impact of OFDI on the industrial structure from three aspects. First, OFDI adjusts the internal structure of enterprises. While conducting OFDI, transnational corporations in emerging economies can obtain new advantages ...
Likewise, energy carriers such as electricity and hydrogen may be described as brown, blue or green depending on their source of energy (Fig. 3). Fig. 3—The color of energy The three major types of brown energy are natural gas, oil and coal. On combustion, natural gas, oil and coal ...
of neuromorphic computing, an important family of models known as reservoir computing (RC) has progressed significantly over the past two decades11,12. RC conceptualizes how a brain-like system operates, with a core three-layer architecture (see Box1and Box2): An input (sensing) layer which ...
After 2015, the change rate of the three major energy types decreased significantly and maintained a certain proportion. This is directly related to Sichuan Province’s 13th Five-Year Plan for Energy Development (hereinafter referred to as the Plan) published in 2015. The Plan points out that ...
