作者 韩民青 《学术研究》 CSSCI 北大核心 2004年第5期37-39,共3页
人类对宇宙认识的视野是不断扩大的 :先前的“宇宙整体”终会演变成后来的“宇宙部分” ,从而认识到更大的宇宙视野 ,形成更大更深远的宇宙新观念。现代宇宙观仍然在遵循着这样一个认识规律而不断演变和拓展。
关键词 现代宇宙 演变趋势 “宇宙部分” “宇宙整体”

A view of the present time is given. As a consequence of the presence of time state, the verses are arranged in couples and every verse including in which we live is a live verse in the same context of human life. This paper interferes with and changes the procedures and philosophy of mathematics itself. Space, mass and time are parts of one whole which is called simply time. The aim of this paper is to make the knowledge of its subject public, so other researchers can contribute to it. The concept of a gate between verses is investigated. 展开更多

An MRPC prototype for the future CBM-TOF inner area has been developed.The counter assembled with low resistive glass consists of 10×0.22 mm gas gaps and 2×8 readout pads.The size of each pad is 20 mm×20 mm with an interval of 2 mm between pads.The signals of the counter are collected by 4 eight-pin connectors.Preliminary tests performed with cosmic-rays showed an efficiency over 98%and a time resolution around 60 ps.The measured crosstalk,dark current and dark rate were at a very low levels.Results under uniform irradiation performed at JINR with high energy deuteron showed a time resolution of40–50 ps and over 98%efficiency at a low flux rate,meanwhile at a flux up to 70 kHz/cm2,93%efficiency and 77 ps time resolution still remained.These excellent performances call fully meet the demand of CBM-TOF inner wall. 展开更多
