In this paper, we report a new Mo-Fe-S cluster complex containing an oxygen ligand. Itwas synthesized by the reaction of （NH4）2 MoS4, FeCl3 in the solution of sodium glycol. The chemical formula of the crystal, [（MoS4） Fe （MoS4O）] [（C4H9）4N]3, was characterized byX-ray. This complex was determined by IR, UV/Vis and Mossbauer spectra as well. The re-suits from Mossbauer spectra of the complex show an isomer shift, δm = 0.2263mm/s and aquadrupole splitting, Eq = 0.4527mm/s. The complex has some activity for the reduetion of aectylene to ethylene in the presenceof KBH4.

This paper bursts the bondage of conventional no-burn thought, presents an optimum strategy permitting burn appear in grinding roughing stage, but the burning layer can be summed on the following finishing stage. On the base of the basic grinding models, the objective function and constrained functions for the multiparameter optimum grinding models had been built in this paper. By the computer simulation, the nonlinear optimum grinding control parameters had been obtained, and the truth grinding process had been controlled by these parameters. The results of simulation and the experiments proved the exactitude of the optimum models and the feasibility of the optimum strategy. This paper had also created the precondition for the grinding automation, virtual grinding and intelligent grinding system for cylindrical grinding process.

A sub-pixel detection corner detection method based on fitting is presented, and mathematic algorithm of the method is in accordance with sub-pixel edge detection, improving the precision of the image measurement. In this paper, based on the geometry that the corner must be the point on the edge and intersection of two edge or many edge points, an algorithm based on the sub-pixel edge to get the intersection is presented. Then the edge equation is acquired by use of the sub-pixel edge detection algorithm in the sub-pixel edge area, the subpixel corner position is found by center of gravity method. And a new evaluation method is also presented, whose criterion is the precision of CCD calibration. In the experiment, comparing to the Bouguet's corner detection algorithms using the new evaluation method, the method of this paper is more precise. Therefore the algorithm is more effective in the field of measuring the dimensions in industry.

α-Fe_2O_3 nanocrystal was encapsulated by a block-copolymer, hydroxylated poly (styrene-b- butadiene-styrene) (HO-SBS) to fabricate composite microspheres with α-Fe_2O_3 cores and HOSBS shell. Its film fabricated on n-Si wafer acts as the insulator layer in the metal-insulator- semiconductor(MIS) structure. The capacitance-voltage (C-V) properties were measured to characterize the composite particulate films.
