A New View on Fuzzy Hypermodules

We describe the relationship between the fuzzy sets and the algebraic hyperstructures. In fact, this paper is a continuation of the ideas presented by Davvaz in （Fuzzy Sets Syst., 117： 477- 484, 2001） and Bhakat and Das in （Fuzzy Sets Syst., 80： 359-368, 1996）. The concept of the quasicoincidence of a fuzzy interval value with an interval-valued fuzzy set is introduced and this is a natural generalization of the quasi-coincidence of a fuzzy point in fuzzy sets. By using this new idea, the concept of interval-valued （α,β）-fuzzy sub-hypermodules of a hypermodule is defined. This newly defined interval-valued （α,β）-fuzzy sub-hypermodule is a We shall study such fuzzy sub-hypermodules and sub-hypermodules of a hypermodule. generalization of the usual fuzzy sub-hypermodule. consider the implication-based interval-valued fuzzy

关于拟AP内射模的一些研究

Let R be a ring. R is called right AP-injective if, for any a ∈ R, there exists a left ideal of R such that lr(a) = Ra (?) Xa. We extend this notion to modules. A right .R-module M with 5 = End(MR) is called quasi AP-injective if, for any s ∈ S, there exists a left ideal Xs of S such that ls(Ker(s)) = Ss (?) Xs. In this paper, we give some characterizations and properties of quasi AP-injective modules which generalize results of Page and Zhou.     

One-Point Extensions of t-Koszul Algebras

We introduce the category of t-fold modules which is a full subcategory of graded modules over a graded algebra. We show that this subcategory and hence the subcategory of t-Koszul modules are both closed under extensions and cokernels of monomorphisms. We study the one-point extension algebras, and a necessary and sufficient condition for such an algebra to be t-Koszul is given. We also consider the conditions such that the category of t-Koszul modules and the category of quadratic modules coincide.     

水玻璃模数快速测定方法的改进

报道了水玻璃模数测定方法的改进,有以下要点:①加入氟化钠过饱和溶液,以保证与二氧化硅充分完全反应;②基本固定取样量,以免取样过多或过少所造成误差;③随试样的分析全过程,作空白试验,以补偿由氟化钠所引起的碱度;④用精密 pH 试纸或 pH 计检测滴定终点.以上改进提高了方法的分析速度和精密度.     

ON Δ-GOOD MODULE CATEGORIES OF QUASI-HEREDITARY ALGEBRAS

A useful reduction is presented to determine the finiteness of △-good module category F(△)of a quasi-heredltary algebra. As an application of the reduction, the f(△)-finitenetess of quasi-hereditary M-twisted double incidence algebras of posets is discussed. In particular, a complete classification of F(△)-finite M-twisted double incidence algebras is given in case the posets are linearly ordered.

HT—6B托卡马克上的MHD扰动模式分析

利用磁探针对ＨＴ－６Ｂ托卡马克上的Ｍｉｒｎｏｖ扰动的大环模数进行了分辨，发现在一次放民过程中ｎ＝１，２，３，４，的模数同时存在，对各模的频谱分析表明，当扰动较小时，各模扰动具有同为２０ｋＨｚ的单一频率，当扰动增大时，各模在２０ｋＨｚ的基础上出现４０ｋＨｚ的倍频，倍频出现的合理解释是磁岛岛宽的振荡。
