项目摘要

HZR_2(PO_4)_3 WAS PREPARED BY THE THERMAL DECOMPOSITION OF NH_4ZR_2(PO_4)_3, WHICH WAS SYNTHESIZED IN ADVANCE BY A HYDROTHERMAL REACTION FROM A STIRRED SOLUTION OF ZROCL_2, H_3PO_4 AND H_2C_2O_4-THE CSN0_3 / HZR_2(PO_4)_3 = 0.4 IMMOBILIZED PRODUCT, TREATED AT 700℃, CONTAINING THE MAXIMUM AMOUNT OF IMMOBILIZED CS (A 0.4 MOLAR RATIO OF CSN03 / HZR_2(PO_4)_3 EQUATES TO APPROXIMATELY 10 WT% OF CS) WAS MINIMAL CS LEACHING RATES IN SEVERAL SOLVENTS AT 160℃ IN AN AUTOCLAVE. THE LEACHING RATE OF CS ION FROM THAT PRODUCT WAS <10^<-6>, 1.0 x l0^<-3>, <10^<-6>, <10^<-6>, 4.7 x 10^<-5>, 2.2 x l0^<-4> AND 2.1 x 10^<-3> G M^<-2> DAY^<-1> IN DEIONIZED WATER, SEAWATER, 0.1 MOL L^<-1> HCL, 0.5 MOL L^<-1> - HCL, 1 MOL L^<-1> - HCL, 1.5 MOL L^<-1> - HCL AND 1 MOL L^<-1> NH_3, RESPECTIVELY, INDIOATING THAT HZR_2(PO_4)_3 REACTS WITH CSN03 TO GIVE A STABLE CS-IMMOBILIZED PRODUOT. ON THE OTHER HAND, THE SR(N0_3)_2 / HZR_2(P0_4)_3 = 0.2 IMMOBILIZED PRODUCT THERMALLY TREATED AT 700℃, CONTAINING THE MAXIMUM AMO … More UNT OF IMMOBILIZED SR (A 0.2 MOLAR RATIO OF SR(N0_3)_2 / HZR_2(P0_4)_3 EQUATES TO APPROXIMATELY 4 WT% OF SR), WAS MINIMAL SR LEACHlNG RATES IN SEVERAL SOLVENTS AT 160℃ INANAUTOCLAVE, INDICATING THAT HZR_2(P0_4)_3 REACTS WITH SR(N0_3)_2 TO GIVE A STABLE SR-IMMOBILIZED PRODUCT.Let H be a finite dimensional pointed Hopf aigebra acting on a prime ring R in an X-outer way, Q the symmetric Martindal e quotient ring of R, K the center of Q, U an intermediate subring of R and A a right comodule subalgebra of K#H containing K. First, I found a counterexample to a result on a Galois-type correspondence theory for the action of H on R given by S. Westreich in 1999. As a resul t of a joint wcrk with Westreith, we showed a I emma on a property of (R#H, U)-subbimodules of Q#H, which implies that the map giving a Galois correspondence is injectivb. We also proved that if the characteristics of the base field is zero, then Λ is a cleft extension over a certain right comodule subalgebra. From this fact, we can give a new proof showing that the correspondence map is surjective and obtain a Caiois-type correspondence theory for X-outer actions of fini te dimensional pointed Hopf algebras on prime rings in the case the characteristics is zero.

以ZrO_2、H_3PO_4和H_2C_2O_4的搅拌溶液为原料，通过水热反应将NH_4Zr_2（PO_4）_3预粉碎后热分解制得HZr_2（PO_4）_3，CSN0_3 / HZr_2（PO_4）_3 = 0.4，在700℃下处理，在160℃的高压釜中，当CsN_（03）/HZr_（2（PO_4）_3）摩尔比为0.4时，CS在几种溶剂中的浸出率最低。在<-6><-3><-6><-6><-5><-4><-3><-2><-1>去离子水、海水、0.1 mol L ~（-1<-1>）HCl、0.5 mol L ~（-1）<-1>HCl、1 mol L ~（-1）<-1>HCl、1.5 mol <-1>L ~（-1）HCl和1 MOL L ~（-1）<-1>NH_3中，产物中CS离子的浸出率分别为<10 ~（-1）、1.0 × 10 ~（-1）、<10 ~（-1）、4.7 × 10 ~（-1）、2.2 × 10 ~（-1）和2.1 × 10 ~（-1）G/天。SR（N0_3）_2 / HZR_2（P0_4）_3 = 0.2的固定化产物在700℃热处理时，AMO含量最高 ...更多信息固定SR的UNT（SR（N0_3）_2 / HZR_2（P0_4）_3摩尔比为0.2时，约为SR的4wt%），在160℃下，SR在几种溶剂中的浸出率最低，表明HZR_2（P0_4）_3与SR（N0_3）_2相互作用，产生稳定的SR-不动积.设H是有限维点Hopf代数，以X-外方式作用在素环R上，Q是R的对称Martindal e商环，K是Q的中心，U是R的中间子环，A是K#H中含有K的右余模子代数.首先，我找到了一个反例，来证明S给出的关于H对R作用的伽罗瓦型对应论的一个结果。1999年的Westreich。作为与Westreith共同工作的结果，我们给出了Q#H的（R#H，U）-子双模的一个性质，这意味着给出Galois对应的映射是内射的.证明了若基域的特征为零，则Λ是某个右余余代数上的cleft扩张。在特征为零的情况下，给出了对应映射是满射的新证明，并得到了素环上有限维点Hopf代数的X-外作用的Caiois型对应定理.少
