| 1 | The structure of a class of Z-local rings显示文摘A local ring R is called Z-local if J(R)= Z(R) and J(R)2= 0. In this paper the structure of a class of Z-local rings is determined. | WU Tongsuo & LU Dancheng Department of Mathematics , Shanghai Jiao Tong University, Shanghai 200240, China Department of Mathematics, Suzhou University, Suzhou 215006, China | 2006 | Science China Mathematics2006，49，10： | 1 |
| 2 | Measurement of solid state nuclear tracks in apatite by thermal analysis method显示文摘A new measurement method of thermal analysis for solid state nuclear tracks is proposed.The annealing heat emitted by the unit mass of solid state nuclear tracks in heavy particles of the sample is determined via micro-thermal analysis method.Hence,the number of solid state nuclear tracks in the unit mass of sample is determined.In particular,this paper introduces the method and its significance to measure the number of α-particles nuclear tracks in apatite by measuring the annealing heat of α-particles nuclear tracks.In addition,the mechanism of the measurement and potential applications are discussed. | HE ShaoRong YANG TongSuo LI TianXiang LU BaiZuo JI ShuLi HENG ShuYun | 2009 | Chinese Science Bulletin2009，54，20： | 1 |
| 3 | Spatial-temporal Variation of Air Temperature for the Recent 40 Years in Lhasa显示文摘It was all known that Lhasa went through a high temperature of 30.8℃in late June 2019,which hit record highs.To better understand the reasons,based on observations recorded at automatic weather stations in Lhasa,the characteristics of temperature variation at multiple time scales were studied using the linear trend method,Mann-Kendall mutation test,Morlet wavelet analysis,R/S analysis and so on.The results showed that:(a)the annual mean temperature(AMT)is rising at a rate of 0.5℃/10 a,and the average temperature for different seasons also increased significantly,especially in winter.(b)Although there was an intersection in 1995,it was found that AMT,did not pass the reliability test of significance levelα=0.05,this means there are no abrupt changes for AMT,the values are 7.97 and 9.15℃respectively before and after the intersection point.(c)AMT has a periodic oscillation for 18-25 and 25-32 a based on a mass of data and the wavelet variance diagrams in Lhasa.AMT has a main cycle of 28 a,cyclic patterns of temperature changes in spring,summer and autumn is similar to AMT,but it is relatively complex in winter.(d)The Hurst index of AMT and different seasons demonstrates that the temperature is likely to continue to rise in the future in Lhasa. | Yang LEI Hongbin WANG Baixue YU Wenxue FU Tongsuo LU Xinyu LIU Dong WEI | 2021 | Meteorological and Environmental Research2021，12，1： | 0 |
| 4 | Zero divisors and prime elements of bounded semirings显示文摘semiring 是类似于一枚戒指的代数学的结构,但是没有要求,那个各个元素必须有添加剂逆。围住的 semiring 是与一份兼容围住的部分订单装备的 semiring。在这份报纸,零个除数的性质和围住的 semiring 的主要元素被学习。特别地,在一些温和假设下面, A 的非零零除数的集合 Z (A) 是 \ ,这被证明 { 0, 1 } ,并且 A 的每个主要元素是一个最大的元素。为有 Z (A)= 的围住的 semiring A \{ 0, 1 } ,如果 ACC 为 A 的元素或为歼灭 A 的理想的主管成立, A 有限地有许多最大的元素,这被证明如果 ACC 为 A 的元素或为歼灭 A 的理想的主管成立。作为主要元素的应用,我们证明围住的 semiring A 的结构被不可分的围住的 semirings 的结构完全决定是否任何一个 | Z (A)|= 1 或 | Z (A)|= 2 并且 Z (A)< 啜 class= “ a-plus-plus ” > 2 0。到可交换的戒指的理想的结构的应用也被考虑。特别地,当 R 有理想的一个有限数字时, poset II (R) 的链建筑群纯、可轰炸,这被显示出,在 II (R) 由 R 的所有理想组成的地方。 | Tongsuo WU Yuanlin LI Dancheng LU | 2014 | Frontiers of Mathematics in China2014，9，6： | 0 |
