The heat generation curves of seven rubber materials used in tires with the changes of temperature have been obtained by using Dynamic Mechanics Analysis technique on NETZSCH DMA242 instrument, knowing that the heat generation of every other rubber materials except inner liner rubber changes lightly alone with the temperature within 10℃~80℃. According to the Fourier law, the heat transfer coefficients of tire rubber are measured by stable method on self-made experiment instrument. The coefficients changes lineally within 20℃~80℃ and the relation formulas λ=λ〓+bt are given out attached with λ〓 and b. The specific heat of tire rubber are measured on Differential Scanning Calorimeter NETZSCH DSC204 and the relations with temperature are linear and the formula is c=c〓+bT, where c〓 and b gained from experiment result data are presented in the paper. The heat convection coefficients on the surface of rolling tire are measured according to the principle of heat-mass transfer analogy principle after simplifying rolling tire into rotating disk with straight movement on wind channel. The relation with rotation speed of disk is linear as h=5. 399+0.0258n and the relation with straight line speed of tire is linear too, h=

Koyama (1960) divided Smilax into six sections according to inflorescence and prophylla etc., and defined the sect. Macranthae as with raceme of one to many umbels, defined sect. Smilax as with umbels sessile on elongate. If it is only one umbel, the peduncle has a node or prophylla at the base. After researching on most literatures on Smilacaceae in different floras, observing most of Smilax specimens in the world .

On the basis of ecologic balance, developing the complex biological preparation as a goal, we first explored two compatibly antagonists to control the leaf disease of forest plant and hoped this two antagonistic fungi could play a cooperative role in controlling the pine needle blight. The main research results were as follows: 1 , The dual test showed the two antagonistic fungi(Gliocladiutm virens ,Bacillus firmus)had some differences to Pestalotia funerea in the inhibition mode. The role of G virens to the P.funerea, mainly displayed the competition in the nutrition and space, but the B. firmus had the distinct inhibition zone to the P.
