本文主要讨论了半素环的微商满足某些分恒等式的问题,给出了如下结果:假设R是带有扩张形心C的素环,I为R的稠密单侧理想,d和g是R的微商,如果d(x)g(x)=g(x)d(x)对任意x∈I均成立,那么对第一个x∈R,d^2(x)=0,或者存在λx∈C使得d(x)-λxg(x)∈C,同时给出了半素环的微商满足某些微分恒等式的结果。 相似文献

The title complex(K(C9H13NO5S2)(H2O)) was synthesized by the reaction of p-tolysulfonyl chloride, taurine and potassium hydrate in water-methanol-ethanol solution. The crystal structure was determined by X-ray diffraction method and the chemical formula weight of the complex is 336.44. The crystal structure of the title complex belongs to orthorhombic space group Pbca and cell parameters: a=0.853 31(12) nm, b=0.820 42(12) nm, c=3.989 4(6) nm. V=2.792 8(7) nm3, Z=8, Dc=1.600 g·cm-3, μ=0.699 mm-1, F(000)=1 400. The compound is an one-dimension chain complex of infinite length which are connected with hydrogen bond and bridging coordination water. The difference and same of the complexes were discussed.

The title compound, [Ni(tssb)(2,2-bipy)2]·5(H2O) 1 (tssbH2 =2-[(E)-(2-oxido- phenyl)methyleneamino]ethanesulfonato, 2,2-bipy = 2,2′-bipyridinyl), belongs to orthorhombic, space group Pbcn with a = 20.3983(18), b = 17.6929(15), c = 17.0897(15) nm, V = 6167.8(9) nm3, Mr = 688.38, Z = 8, Dc = 1.481 g·cm-3, F(000) = 2880, μ = 0.758 mm-1 and S =1.099. Each NiII atom is six-coordinated by one N and one O atoms from one tssb2-anion and four N atoms from two 2,2-bipy ligands to give a distorted octahedral geometry. Noticeably, there exists a rare octa-membered water ring which presents a 1D chain by sulfonic group. 相似文献
