The results indicate that the largest deformation appear on the middle region of the addendum, the position of largest stress appears at the dedendum region of loaded tooth. As the curvature radius of transition curve rising, both the largest deformation and the largest dedendum stress reduce.

结果表明，内齿圈的最大变形出现在齿顶的中间部位，而最大应力出现在受载齿的齿根部位；内齿圈的最大变形和齿根最大应力随着齿根过渡圆角半径的增大而减小。

These compounds are of substantial interest both inviewpoints of theory and practical applications, mainlyunder the stimulus to achieve synthetic models either foractive sites of iron-sulfur proteins or for transitionmetal catalysts. This thesis describes the synthesis, structures andconformations of 51 new iron-sulfur cluster complexes,which have been characterized by elemental analysis andstandard spectroscopic methods. In addition, single-crystalX-ray diffraction analyses were performed for 4 representa-tive new compounds. Reactivities of μ-〓 with mono- and di- Grig-nard reagents derived intermediates toward various organicelectrophilic substrates were studied, along with complexa-tion of arynyl-containing iron-sulfur clusters by 〓Thus, several bridged, non-bridged, monomeric, dimeric,homonuclear, heteronuclear iron-sullfur and iron-sulfur co-balt-carbon cluster complexes were synthesized. A novelreaction and convenient route for the synthesis in highyield of tetranuclear iron complexes 〓 containing atetracoordinated sulfur atom was discovered, whereas aplausible mechanism based on experimental results was propo-sed for the formation of the new cluster type.

The structure of the compound 〓(1) consists of a pentanuclear molecule which is center-symmetric. One W atom is coordinated by four S atoms and two Cu atom. As expected, the Fe atoms are sandwiched between two staggered pentadiene rings. The most interesting aspect of the structure is that Fe-C-P-Cu-P-Cconstitutes a distorted hexagon and Fe-Cu-W-Cu-Fe is nearly in a line.

The results of batch experiments showed that the anaerobic biodegradation kinetics of 2-CNB and 4-CNB by granular sludge were follwed by first-order reaction. The nitro groups of 2-CNB and 4-CNB were more easily attacked by electron than chlorines and they were reductively biotransformed to amino groups under anaerobic conditions. The acclimated anaerobic granular sludge, which could dechlorinate 4-chloroanline to aniline, showed that it had the ability of para-dechlorinating. The anaerobic biodegradating on pathway of 2-CNB and 4-CNB were suggested as follows:AbstractIn ZVI(zero-valent iron, Fe0)-reduction system, the nitro groups of 2-CNB and 4-CNB were reductively transformed to amino groups.
