本文回顾了1983年以来一些对太阳活动的谱分析结果。大致可分为两种规律:在太阳活动11年周期的上升相一般呈现80天左右的周期。下降相呈现150天左右的周期。这些规律均是由太阳全日面总体活动指数得到的谱分析结果。文中将... 本文回顾了1983年以来一些对太阳活动的谱分析结果。大致可分为两种规律:在太阳活动11年周期的上升相一般呈现80天左右的周期。下降相呈现150天左右的周期。这些规律均是由太阳全日面总体活动指数得到的谱分析结果。文中将第22周上升段(1987.1.1—1988.7.31)的太阳黑子群和X射线耀斑按经度带作了极大熵谱估计。结果表明,各经度带的活动规律不同,同一经度带内,太阳黑子群和X射线耀斑的出现规律也不尽相同。这种将事件按经度带分布得到的活动规律对事件本身的中期预报将会有实际应用价值。 展开更多

China is the starting point and pioneer and driver of the Silk Road Economic Belt; Russia is located in the throat place of the belt; and India is at the joint of the belt and the Maritime Silk Road. China, Russia, and India as the BRICS countries are geo-connected, easy to reach a consensus because of their common and similar interests. The three countries also have common inherent demands and strategic directions: connectivity, complementarity, taking advantage of the great powers of Eurasia and sea-land compound, moving toward the grand trend of modern international economy and technology development. Promoting the construction of the Silk Road Economic Belt accords with their respective interests, and is their common interests, which decide that China, Russia, and India are the key factors and dominant forces in the construction of the belt. 展开更多

Empirical orthogonal function (EOF) analysis reveals a co-variability of Sea surface temperatures (SSTs) in the Southern Hemisphere (0°-60°S). In the South Indian and Atlantic Oceans, there is a subtropical dipole pattern slanted in the southwest-northeast direction. In the South Pacific Ocean, a meridional tripole structure emerges, whose middle pole co-varies with the dipoles in the South Indian and Atlantic Oceans and is used in this study to track subtropical Pacific variability. The South Indian and Atlantic Ocean dipoles and the subtropical Pacific variability are phase-locked in austral summer. On the inter-decadal time scales, the dipoles in the South Indian and Atlantic Oceans weaken in amplitude after 1979/1980. No such weakening is found in the subtropical South Pacific Ocean. Interestingly, despite the reduced amplitude, the correlation of the Indian Ocean and Atlantic dipoles with E1 Nino and Southern Oscillation (ENSO) are enhanced after 1979/1980. The same increase in correlation is found for subtropical South Pacific variability after 1979/1980. These inter-decadal modulations imply that the Southern Hemisphere participates in part of the climate shift in the late 1970s. The correlation between Southern Hemisphere SST and ENSO reduces after 2000. 展开更多

The purpose of this article is to analyze China's economic development policies of the last few years from the viewpoint of some Mexican actors (businesspeople, public officials, and scholars) who live and work in China. The idea is to learn from these policies and perhaps transfer the best practices to Mexico through horizontal international cooperation, with the hope of contributing to Mexico's growth and development, based on its reality. We put forward that there are international circumstances that could bring this about, thanks to sudden changes on the global scenario. Finally, the article highlights the importance of fostering, understanding, and deepening bilateral relations between Mexico and China. 展开更多
