Abstract： High temperature liquid chromatography（HTLC） is a new field in the development of chromatography. Kinetic and transport properties can be particularly enhanced, which are based on the decrease of the viscosity of mobile phase and increase of the analyte diffusivity at higher temperature. The separation can be achieved with high flow rate and the pressure of the system can be also reduced at high temperature. Under the high temperature, not only the analytical time can be shortened, but the peak symmetry can be improved and the use of organic solvent can be decreased as well. Depending on HTLC, subcritical water choromatography has been developed, which accords with Green Chromatography best. At the same time, the range of liquid chromatography has been widened. The effects of temperature on column performance, retention, selectivity, and column stability are reviewed and applications of HTLC are introduced in this paper.

Abstract: A definitive power spectrum was deduced from theoretical analysis and a universal equation was obtained in the paper “Statistical Dynamics of 1f Noise”. But there still are some questions such as why the power spectra S（f） of 1f noise show the same form fined in experiments, energy spectrum and power spectrum have the same function form etc. which were discussed here. To go a step further, the authors explained the universal equation S（f）∝1f based on the “fluctuation of background” from the theorem of “zero point energy” and “dark matter”.

TANG Jin-e， ZHANG Xiu-rong
（Centre of Physic Laboratory，Shanxi University， Taiyuan 030006，China）
Abstract: The Rayleigh interferometer is a precise instrument that can be used to survey the refractive index of liquid and gas. However， the deflection position of the compensator influence the accuracy of measurement directly. On the basis of testing a series of optical distance difference corresponding with the deflection angle of compensator， the article discussed the optimum compensation scope. The results indicate that the position with a deflection angle of 30 degrees from the horizontal direction is the best initial position of the compensator. The largest compensation angle of our experiment is 5 degree and the experiment offers the experimental parameters for accurate survey through the Rayleigh interferometer.
