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.

摘 要：在《1f噪聲的動(dòng)力學(xué)統(tǒng)計(jì)理論》一文中，為了突出重點(diǎn)，攻克主要矛盾，因而對1f噪聲的某些特點(diǎn)，如實(shí)驗(yàn)上發(fā)現(xiàn)的1f噪聲的功率譜S（f）為什么總是1f？能譜和功率譜S（f）為何是同一函數(shù)等等，當(dāng)時(shí)未能深入追究，本文除了彌補(bǔ)這些不足之外，還從“零點(diǎn)能”與“暗物質(zhì)”而引發(fā)的“背景能量的涌動(dòng)”這個(gè)深層次上來解釋普適關(guān)系式：S（f）∝1f。

XU Sheng-long
（Kunming Institute of Physics，Kunming 650223，China）
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”.

（Water Quality Monitoring Center of Handan City Running Water Company，Handan 056003，China）
Abstract: The process of total nitrie determination in water by on-line reaction was described in this paper. Persulphate was photo-degradated into kraft radical by on-line UV digestor, inorganic or/and organic nitride in sample was oxidated into nitrate by the kraft radical, and the nitrate would be reduced into nitrite. The red complex formed through reaction of nittrite and sulfanilamide/NEDD could be detected at 550nm. The recovery of this method is 96～103%, relative standard deviation（RSD） less than 1.2%, and its repeatability and sensitivity are very well.

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.
