It is analysed the discrepancy about the coronal magnetic field between solar optic and solar radio using magnetic fibril concept with filling factor and fractal structure model. The magnetic field of ~ 100 G considered in solar optics is mean value in a large scale, and that of ~1000 G in solar should be the value of fine structures inside 'macro' loop.

It. has been discovered that. active regions commonly have numerous flare-like transient. loop brightenings. We use a magnetic reconnection theory driven by a ponderamotive force on account. of the basic properties of a transient. brightening: lifetime a few mins, total energy 10 25~10 29 erg. The numerical results are consistent with the observations.

In this paper, we present observations of absorption line spectrum of QSO 1225+317 with resolution of 18 km sec-1. Four possible new heavy element line systems are identified. The properties of Lyman α forest lines are discussed.

We have examined morphological change and movements of individual sunspots within a sunspot group in association with a large solar flare activity (3B/X1.5) appeared on 13 May 1981. For this purpose we measured distance among spots during the period before and after the flare activity and estimated the average velocity of their movement. Our main results are as follows: (1) The longitudinal displacement among sunspots are generally greater than the latitudinal displacement. (2) During the period the spots moved with an average velocity of 1.2 km/s in longitude and 0.86 km/s in latitude. (3) The most notable change took place in the central part placed between the two ribbons of the flare.

With the wave of digital economy sweeping the world, artificial intelligence, blockchain, cloud computing, 5G, ChatGPT and other information technologies are developing rapidly. All walks of life are undergoing changes, and people’s thinking, cognition, life, study, and work are changing accordingly. Both developed and developing countries are also facing new situations and challenges in politics, economy, science and technology, culture, and education. It can be said that digitalization itself and its impacts are related to the development of the future world and affect every citizen of the earth. Digital literacy and skills derived from digitalization have gradually become the focus of attention from all walks of life. In terms of college students’ digital literacy and digital literacy skills, it mainly refers to the digital ability that college students should have and use in study, employment, and future work under the background of informatization and digitalization. Although digital literacy and digital literacy skills have been paid more and more attention by the international community and schools, there is no unified definition of digital literacy and digital literacy skills by various countries and international organizations, and there are some differences in the use of this concept by countries and regions. From the perspective of enterprises’ demand for digital talents, this paper puts forward some suggestions on the training and improvement of college students’ digital literacy skills.

Under the background of economic globalization, the trade between countries in the world is increasing rapidly. Under the rules of WTO, the tariff rate of trade barriers is decreasing, but on the other hand, nontariff barriers are increasing. especially Compared with tariff barriers, green trade barriers have a greater impact on agricultural trade. Therefore, the negative impact of green trade barriers on agricultural products trade is a problem worthy of attention and urgent response in the future agricultural products trade between China and South Korea. Firstly, this paper analyzes the meaning and characteristics of green trade barriers, introduces the current situation of agricultural products trade between China and South China, analyzes the influence of Korean trade barriers on’s agricultural products export trade, and on this basis, forms countermeasures to promote Chinese agricultural products export to South Korea. The research of this paper has certain guiding significance for promoting Chinese agricultural export trade to South Korea.

In recent years, with the increase of people’s automobile travel, the traffic has become more and more congested, and the generated automobile exhaust aggravates the environmental pollution. In order to realize the development of the concept of low carbon and environmental protection, China’s new energy vehicles have developed rapidly, and plug-in hybrid vehicles have played a crucial role in the transformation of the automobile industry. China’s plug-in hybrid vehicle industry has developed so far and has become an important production and sales country in the world. Based on this, this paper studies the current situation and existing problems of China’s plug-in hybrid electric vehicle export trade, and proposes improved countermeasures, which is conducive to improving the export competitiveness of China’s plug-in hybrid electric vehicles.

After the outbreak of the epidemic, China’s foreign trade industry has been greatly impacted, and the survival of Chinese export enterprises in the post-epidemic era has become more difficult, and the surge in Sino-US trade frictions has further aggravated the difficult status quo of China’s export industry. This paper studies the relationship between marketing ability and export performance through literature research and mathematical analysis, aiming to help Chinese export enterprises get rid of the current situation of downturn, improve market competitiveness, and put forward feasible guidance strategies for improving the export performance of Chinese enterprises.

The ongoing impact of global inflation, economic pressures and the current complex international geopolitical and trade situation have created new challenges for international settlement activities, including debt recovery. One of the characteristics of international documentary collections is to obtain payment mainly relies on the commercial credit of the payer, rather than the bank’s bank credit, so the risk is relatively high. We use the typical stationery misuse -- from the perspective of export companies -- to analyze the problems and risks of stationery itself, and put forward relevant measures to avoid and evade risks. We hope that practitioners living in this field can learn from it.

The RCEP rules are the basic guarantee for the settlement of international trade competition disputes. Only by establishing fair competition in relevant markets can the objectives of the Free trade Agreement be fully realized. Therefore, we should study the RCEP rules and summarize the shortcomings of the RCEP rules. In view of these deficiencies, a scientific and reasonable solution to the RCEP international competition dispute settlement rules will be found to solve the practical difficulties existing in the relevant rules of international competition dispute settlement, so as to promote the better realization of the objectives and purposes of international competition dispute settlement, and ultimately provide a fair market environment for further promoting the development of foreign trade of all countries.

RCEP, through its unique rules of origin accumulation, promotes mutual tariff concessions between Korea and China, reduces trade production costs, and will further promote the negotiation of the Korea-China FTA. Focusing on the post-epidemic era, South Korea and China should strengthen the consensus on economic and trade cooperation and use the higher standard and more comprehensive RCEP agreement to achieve a mutually beneficial and win-win situation. The industrial supply chain between South Korea and South Korea is the result of the spontaneous formation of the market, mutual benefit and win-win results. Third-party markets such as the Far East can better cooperate to provide impetus for the economic development of the two countries and the recovery of the world economy.

Thermospheric wind observations from high to mid latitudes are compared with the newly developed Multiscale Atmosphere Geospace Environment (MAGE) model for the Nov 3–4 geomagnetic storm. The observation and simulation comparison shows a very good agreement and is better at high latitudes in general. We were able to identify a thermospheric poleward wind reduction possibly linked to a northward turning of the Interplanetary Magnetic Field (IMF) at ~22 UT on Nov 3 and an enhancement of the poleward wind to a southward turning near 10 UT on Nov 4 at high latitudes. An IMF southward turning may have led to an enhancement of equatorward winds at Boulder, Colorado near midnight. Simultaneous occurrence of aurora may be associated with an IMF By turning negative. The MAGE model wind simulations are consistent with observations in these cases. The results show the model can be a very useful tool to further study the magnetosphere and ionosphere coupling on short time scales.
