Thermal regeneration ofhypercrosslinked polymeric adsorbent （HPA） was performed at 67℃. Experiments were carried out using a multimode microwave oven operating at 2450 MHz and a thermostatic water bath so as to compare the effect of the different heating mechanisms on the regeneration efficiency of the HPA saturated with nitrophenols. The temperature rise action of the heterogeneous regeneration system under microwave irradiation was described. Additionally, a complete structure and chemical characterization of the regenerated HPA was also carried out in order to study the influence of the subsequent regeneration cycles on the structure and the adsorption capacities of the adsorbents. Structure characterization of the regenerated HPA was accomplished by means of the analysis of FTIR spectra.

The nanocrystalline microstructure of the surface of 316 stainless steel （316SS） induced by surface mechanical attrition treatment （SMAT） was determined by X-ray diffraction （XRD） and scanning electron microscopy （SEM）. The technique of hydrogen embrittlement was first used to obtain the information of the brittleness cleavage plane. The effects of SMAT and the following annealing process on the corrosion behavior of 316SS were investiga- ted by potentiodynamic polarization curves and potentiostatic critical pitting temperature measurements. The results demonstrated that the nanoerystalline layer with an average grain size of 19 nm was produced. However, there were lots of cracks on the surface, which led to the degradation in the corrosion resistance of 316SS after SMAT. Never- theless, after annealing treatment, the corrosion resistance of the nanocrystalline surface had been improved greatly. The higher the annealing temperature, the better was the corrosion resistance.

Hypocrellin A and B in methanol were autosensitized and photooxygenated to 1,4,6, 7 and 2,5,8,9 respectively.1 in methanol was photooxygenated to 6 and 7 under the sensitization by HB.1 in methanol was photooxygenated to 7 under the sensitization by Rose bengal.1 in benzene ir- radiated with medium-pressure-mercury lamp was photolyzed to 3 in the presence of iodine.

The UV-VIS spectroscopic studies of phycoerythrobilin dimethyl ester, phycocyanobilin dimethyl ester and their derivatives indicate that shortening of the conjugative systems induces hypsochromic shifts in wavelength and increases in molar extinction coefficients in visible part;both zinc ion coordination and acetic acid treatment induce bathochromic effects for the phycobilins and their derivatives.

Various silatrane compounds were studied by means of15N NMR spectroscopy. Thequantum chemical calculations of some of the compounds were carried out using CNDO/2 *** following correlations were obtained, i. e.,15N chemical shifts vary linearly with Taft's polar sub-stituent constants σ*（s） of the substituents R on the silicon atoms, and also with the net charge den-sities on the nitrogen atoms. From both experimental and theoretical aspects, it could be concluded thatthe Si←N dative bonds in a series of silatrane compounds actually exist.

To the Editor： Ophthalmoplegia can cause diplopia, with a lot of etiologies including cerebrovascular disease. Nuclear ophthalmoplegia resulted from brainstem infarction is often accompanied by other symptoms of brainstem dysfunction. It is fairly rare that midbrain infarction only manifests as isolated medial rectus nuclear palsy. Here, we provided such an uncommon case and discussed the possible etiology.
