This text uses the regional geological investigation data and the remote sensing image data of earth-satellite remote sensing to synthetically analyze the structural system of Taiwan region of china. Authors detection-marked and assurance-marked and divided 5 kinds of structural system of the Taiwan region: (1) the wreath-shaped structural system, (2) the N-N-E oriented structural system, (3. the S-N oriented structural system, (4) the N-E oriented structural system, (5) the arc-shaped structural system. Combination of the texture faces and associated method were adopted to recover and reconstruct the structural evolution sequences and the formation periods. In this paper, problems such as the development process in geology etc. are also discussed, contributing new information to research the structural field of the East Asia and its tectonic plate movements and structural actions inside the land plate .

Monodisperse titania glycolate submicrospheres were synthesized by a modified sol-gel route, in which ultrasonic treatment was introduced to improve the reaction efficiency. The as-prepared products were characterized by means of Fourier transform infrared spectrum （FT-IR）, transmission electron microscopy （TEM）, powder X-ray diffraction （XRD）, and scanning electron microscopy （SEM）. The results indicate that the as-prepared products are titania glycolate submicrospheres with diameters of 23.-3.0 nm. The average particle diameter is estimated to be about 280 nm. Ultrasonic treatment has an important influence on the morphology of the produced titania glycolates. After calcination at 450°C for 2 h, these titania glycolates were completely converted into anatase TiO2. The morphology of TiO2 particles was well reserved during the calcination process except for a reduction of 18% in the average particle size.

The reduction of Fe3.4 to Fe is accomplished in two stages. In order to understand the reduction mechanism of magnetite cold bond pellets during the first period of heatingup process, it is necessary to study the kinetics of the reaction. In this work, the first stage of reduction of magnetite cold bond pellets, that is the reduction from Fe3.4 to FeO, has been investigated using an isothermal thermogravimetric method. Isothermal experiments were carried out at 750℃, 800℃, 850℃ and 900℃, respectively. The results showed that the reaction was controlled by chemical reaction below 800℃, whereas, at higher temperature, it was controlled by a mixed controlled mechanism of chemical reaction and GinstlingBrounshtein diffusion as well.

The research of X ray powder diffraction indicates that glasses form at the temperature of about 1025 in the system of 20BaO (10-x)La2O3.·90B2O3.·xEu2O3.(BLBE). The study of luminescence spectra reveals that in this system, there have existed two valence ions: Eu2+ and Eu3.. The acute excitation bands peaking at 3.6,3.0, 3.9 , 3.3. 413.462and53.nm ,the red -region emission bands peaking at 592, 616, 650 and 750nm correspond to the f-f excitation transition and the emission transition of 5D0 - 7FJ (J=l,2,3.4,) of Eu3. ions, respectively. Likewise, the broad excitation bands peaking at 43.nm and 53.nm correspond to the 5d-4f excitation transition of Eu2+ ions, and the blue emission bands to the emission of Eu2+ ions. The experimental result that the introduction of Gd3. ion can distinctly improve the emission intensity ratios of the blue-light and red-light of the glass indicates that the main process of energy transfer is Gd3. →Eu2+→Eu3. in BLBEG system .
