The response behaviors of ion_selective electrodes prepared by five novel amido tripodal compounds are investigated.

Two novel tripodal compounds: 1,1,1-tris-(1-benzoltriazolyl- methoxymethyl)propane and tris[2-(1-benzoltriazolylmethoxy)ethyl]amine are synthesized.

Progress in the research of tripodal compounds with N as central atom;

To study the coordinating relations between tripodal ligands and the fluorescent properties of rare earth ions and their complexes, a tripodal ligand,2,2,2-amine tri acetyl-pyridine and its 6 complexes with rare earth nitrates are synthesized.

In order to study composition,compared probable coordination structure and fluorescence propertiesof tripodal and their rare earth complexes a tripodal compounds containing 2,2,2-amine tri-acetyl-benzylamine (L)and the its six rare earth complexes were synthesized which was characterized by IR,1H-NMR,elemental analysis,thermal analysis,molar conductivity,fluorescence spectrometry and so on.

This paper presents the dynamic modification and re-analysis of a tripod mount structure used in the machine gun.

This paper gives a relative sensitivity analysis method for predicting the dynamic modification of a tripod structure.

To study the composition,compared probable coordination structure and fluorescence properties of tripodal and their rare earth complexes,a tripodal compound containing 2,2,2-amine tri acetyl-dibenzylamine(L)and its six rare earth complexes are synthesized.
