Yoshi is a world-renowned igneous petrologist and authority on magma generation and evolution associated with subduction zones. He uses magmatism as a tool to understand the evolution of the solid Earth. He has published over 120 research papers in leading journals such as Nature, Science, Geology, Earth and Planetary Science Letters, Journal of Geophysical Research, Journal of Petrology, Contributions to Petrology and Mineralogy, Chemical Geology, etc. Every igneous petrologist today, in particular those who study the petro- genesis of subduction-zone igneous rocks, is impressed with and influenced by Yoshi＇s classic book 《Subduction Zone Magmatism》 （Tatsumi Y. and Eggins S., Blackwell Publishing, 1995, 1--224）, which has been widely cited in research papers and used in classrooms. His thinkina goes bevond magmatism.

Evidence for tritium production in the Earth’s interior

We have made a new investigation on the vertical profiles of tritium and helium isotopes in Lakes Van and Nemrut （Eastern Turkey）, using experimental data from the reference by Kipfer et al. for study of long-term vertical mixing and deep water renewal in Lake Van. Lakes Van and Nemrut are crater lakes. Lake Nemrut is at the western border of Lake Van. The ^3He and ^4He are injected at the bottom of Lakes Van and Nemrut, and the both helium isotopes are confirmed from the mantle source. From ^3H （tritium） data in Lakes Van and Nemrut, we have observed ＂^3H anomaly＂ at the vertical profile of ^3H concentrations in Lake Nemrut. The ^3H concentration at the lake bottom is 10% higher than at the surface. The difference of ^3H concentrations between surface and bottom is about 3.7±1.2 TU. This excess ^3H should be injected from the lake bottom. An investigation on the origin of the injected tritium has been made. The results show the conventional origins are excluded, such as residence of precipitation tritium from nuclear testing in the early 1950s--1960s and tritium from known nuclear reactions. Based on the correlation of excess ^3H with ^3He and heat flow in Lake Nemrut, we infer that the ^3He and ^3H might be all from the mantle source, and produced by the supposed natural-nuclear-fusion, which might occur in an environment rich in water （H） and （U ＋ Th） at high temperature and high pressure in the deep Earth. Detection of tritium in the Earth＇s interior is a key evidence for exploration of natural nuclear fusion in the deep Earth. Based on the published data, we have found that the excess ^3He and ^3H injected at the bottom of Lake Laacher （Germany） were also released from the mantle source. The present work will be helpful to the further study of mechanism of natural nuclear fusion in the Earth＇s interior.

聚焦马拉松：中国马拉松现象的三维透视

Marathon fever is suddenly sweeping across China. Since 2014, city marathons have been the fastest developing and most influential road running races in China with the largest number of participants. According to the Chinese Athletic Association, 53 marathons were held in China in 2014, 134 in 2015, a sharp increase of 14% on 2014, and the number reached 328 in 2016, with over 2.8 million runners. In 2017, there were 1102 marathons and marathon-related road running races in China with no fewer than 800 runners each, and nearly 10 million participants. It can be argued that marathon races are becoming a sports carnival and the name card of the development of a city in China. But there are also many questions worth exploring: Why is the marathon suddenly so popular? What are people’s experiences like with running the marathon? What problems does it reveal? And how will it impact economy? etc. Sports Review in this issue publishes articles by Ji Chenglong, D. Mgt. at Jiangxi University of Finance and Economics, Sun Ke, Ed.D. at Beijing Institution of Education and Chen Guoqiang, Ph. D. in Journalism and Communication at Shanghai University of Sport. They will discuss the marathon mania in China from the perspectives of the market, society and race participation.

Brief Introduction to ＂Journal of Jilin University （Science Edition）＂

＂Journal of Jilin University （Science Edition）＂ is a comprehensive academic journal in the fields of science sponsored by Jilin University and administrated by the Ministry of Education of the People＇s Republic of China. The journal started publication in 1955. The original name at starting publication was ＂Journal of Natural Science of Northeast People University＂, which was changed into ＂Acta Scientiarum Naturalium Universitatis Jilinensis＂ in 1958 owing to the name change of the university. The present journal name has been begun since the beginning of 2002 after a new Jilin University was set up, which comes from the amalgamation of the original Jilin University, Jilin University of Technology, Bethune Medicine University, Changchun University of Science and Technology and Changchun Post and Telecommunication Institute on June 12, 2000. The domestic journal number is CN 22-1340/O, and the international journal number is ISSN 1671-5489.
