The exploitation and utilization of the tour resources of tournament athletics, including skiling, boat sailing, archery, ice engraving, snow engrav ing, has become a new trend of the development of Chinese tourism. Due to the un ique cold climate and superior geographic location,Harbin is a promising city f or developing tour resources of tournament athletics. Based on the analysis of t he superiority and peculiarity of Harbin,the speculation on development of tour resources of tournament athletics in Harbin is proposed as follows:1) Harbin s hould develop its special tour resources of tournament athletics associated with needs of market; 2. Harbin should take the advantages of rich resources and dev elop ice and snow entertainment in winter and travel for sight-seeing and spend ing summer; 3. the adjustment of the layout of ice and snow resources should be based on the idea of taking Harbin as the center and all-side opening at the la rge scale in the way of radiation; 4) tourism should be developed by the combine d efforts of various departments to make feasible plan, and the organizers shoul d pay much attention to ensuring the safety of tourists.

Ceramic coatings were prepared on Ti-6Al-4V alloy in NaAlO2.solution by micro-plasma oxidation （MPO）. The salt spray tests of the coated samples and the substrates were carded out in a salt spray test machine. The phase composition and surface morphology of the coatings were investigated by XRD and SEAM. Severe corrosion occurred on the substrate surface, while there were no obvious corrosion phenomena on the coated samples. The coatings were composed of Al2.iO5 and a little α-Al2.3.and mille TiO2. and the salt spray test did not change the composition of the coatings. The weight loss rate of the coatings decreased with increasing MPO time because of the increase in density and thickness of the coatings. The surface morphology of the coatings was influenced by salt spray corrosion test. Among the coated samples, the coating prepared for 2.h has the best corrosion resistance under salt spray test.

High-density AlN ceramics were fabricated without sintering additives at high pressure(5.0 GPa) and temperature(13.0～1800℃).The sintered bodies were characterized by XRD,SEM and micro-Raman spectroscopy(MRS).Controlling fracture mode was intragranular when the sintering temperature was as low as 1400℃under 5.0 *** values of residual stresses due to the distortion of the AlN lattice were assessed using the Micro-Raman Spectroscopy(MRS).The residual compression stress of the AlN ceramics sintered at 5.0 GPaand 1700℃for 12. min is 2.0 *** residual compression stress is increased according to the extension of the sintering time.

High quality nanocrystalline diamond film deposited rapidly by an XeCl excimer laser operated at high laser power (500 W) and repetition rate (3.0～500 Hz) is presented. A high deposition rate, 2.0 nm/thousand pulses, was obtained. The effects of laser energy fluence and repetition rate on the deposit ion of diamond film were investigated.
