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=

Phenotype analysis of transgenic mice Anti-IgM/anti-IgD antibodies, anti-IgM/anti-IgM〓/anti-IgM〓 antibodies were used to analyze allelic exclusion of transgenic mice B cells, and it was shown that 50%～80% B cells express transgene encoded IgM. ELISA was used to evaluate serum antikeratin IgM and total IgM of transgenic mice peripheral blood, and it is found that sera antikeratin IgM level of several lines of transgenic mice is significantly higher than littermate control. However, there is no difference in serum total IgM level between transgenic mice and non-transgenic mice.

CPL language based on ALGOL 60 close to the hardware, but relatively large scale, it is difficult to achieve. University of Cambridge in 1967 of the Matin Richards made to simplify the language of CPL, the introduction of the BCPL (Basic Combined Programming Language) language. In 1970 the United States Ken Thompson of Bell Labs to the basis of language BCPL, but also further simplified the design of a very simple hardware and is very close to the B language and language with B first UNIX operating system, the PDP-7 to achieve.
