IR and EXAFS spectra of two binary Oxide glassesBi_2O_3-GeO_2 and Bi_2O_2-B_20_3 are measured, the effect of Bi~(3+) on B-O, Ge-O network structure are analysised, and the local structure of Bi~(3+) in oxide gla- sses have been discussed. The results show: Bi_2O_2 can introduce some non-bridging oxygens in Bismuth Geramanate glasses to depolyme- rize the Ge-O tetrahedran network; it can give part of its oxygens to the Boron in Bismuth Borate glasses to create four-coordinated sites. Asymmetric [BiO_6]...

本文测定了铋锗酸盐、铋硼酸盐玻璃的IR光谱和EXAFS谱,分析了Bi~(3+)对B-O、Ge-O网络结构的影响,讨论了Bi~(3+)在氧化物玻璃中的结构形态。结果表明:Bi_2O_3能够给锗酸盐玻璃提供非桥氧,使[GeO_4]四面体构成的结构网络解聚;Bi_2O_3能够提供游离氧给硼酸盐玻璃,使[BO_3]三角体转变成[BO_4]四面体。晶体中不规则的[BiO_6]八面体在玻璃中产生了更为严重的畸变,使极化率很大的Bi~(3+)离子在氧化物玻璃中可能以低配位的[BiO_3]基团形式存在。

Six complexes of palladium ( Ⅱ ) with meso- and race-diastereoisomeric RS(O)CH2CH2-S(O)R(abbr. to meso-, race-BXSE. R = n-C3H7, C6H5, n-C8H17, X = Pr, P, O) were prepared. The crystal structures of PdCl2-meso-BPrSE ( I ) and PdCl2.race-BPrSE( Ⅱ ) were determined. Crystal data: I : P212121, a = 9. 3650(9), b=9.747(2), c=19. 341(5) A , Z=4, R=0. 044; Ⅱ: Ibca, a = 9. 442(1), 6=15. 386(4), c = 20. 095(3)A , Z=8, R=0. 030.The IR spectra indicate that the ligands are bonded to Palladium ( Ⅱ ) via sulfur atoms to form the cis-chelated complexes, which has been confirmed by the crystal Structures. △vso[vso complex -tvso ligand] for different R groups varies in the order: meso-BPrSE- race-BPrSE>meso-BOSE- race-BOSE> meso-BPSE- race-BOSE.I has a C1 symmetry and Ⅱ has C2 symmetry. The four coordinated atoms around palladium (Ⅱ ) form a right square plane for Ⅱ and a only slightly tetrahedrally distorted plane for I . It can be concluded that the higher melting point BPrSE is of meso form and the lower melting point BPrSE is of rac form.

In order to substitute for manual manipulation, presents a new process used to manufacture the mould figure composed of curved faces in space. Using the numerical control system with two turning coordi- nated axes and one simple direct copy, the numerical control machine tool attains such function as which is based on four coordinated axes necessary. In the processing and contrilling, the function trace method is used to interpolate, and the offset calculating function is supplemented for need of tool replacement, so any complicate figure can be worked with it convenintly.
