A STUDY ON THE SPECTRUM CHARACTER AND PHOTOSTABILIZATION ABILITY OF A NOVEL UV-ABSORBER-DIBENZOYL METHANE

The absorption and fluorescence spectra of dibenzoyl methane have been studied. From the absorption spectra it was found that there are two peaks locating at 252 nm and 340 nm, respectively, similar to that of o-hydroxy benzophenone which can form intra-molecular hydrogen bond. Besides, an uncommonly large Stoke's shift of fluorescence can be observed in fluorescence spectra. The photostabilizing effects of dibenzoyl methane and UV-531 on the photodegradation of poly (cis-1, 4-butadiene) in solution have been investigated and compared. A possible mechanism was discussed.     

STUDY ON THE CONDUCTIVITY OF A COMPLEX INORGANIC ION EXCHANGER-a-ZIRCONIUM PHOSPHATE MIXED WITH SILICA

The composite of α-ZrP and fumed silica was prepared by dispersing predetermined molar ratios of polycrystalline α-ZrP in water. Admittance measurement of the samples was made in the frequence range from 5Hz to 1MHz and the temperature range from -20℃ to 20℃. The activation energy in conduction of the composites, with different molar fraction of α-ZrP, is about 5. 9KJ/moL at 60% and 40 % relative humidities. The results show that the charge transport mechanism was not changed after mixing fumed silica into α-ZrP and the charge transport medium is water in α-ZrP and the composites.

A STUDY ON THE RECEPTIVE FIELD OF ACUPOINTS AND THE RELATIONSHIP BETWEEN CHARACTERISTICS OF NEEDLING SENSATION AND GROUPS OF AFFERENT FIBRES

We have recorded the afferent unit discharges and using it as an index, measured the locations and the volumes of nine acupoints, such as Neiguan and Shaoshang, which are innervated by median nerve. We have also investigated. the relationships between electric needling sensations and afferent fibres of different groups as well as manual needling sensations by means of analysing power-spectrum of the unit discharges with FFT. It has been found that the fibres of Group Ⅱ and Group Ⅳ convey numbness and soreness, respectively. The fibres of Group Ⅲ relates to the conduction of heaviness and distention closely.     

A STUDY ON THE INTERACTION BETWEEN CH_3OH AND H_2CO MOLECULES IN TERMS OF THE PROPERTIES OF CHARGE DENSITY DISTRIBUTIONS

Two possible complexes formed by the interaction of CH_3OH and H_2CO,one hydrogen-bonded(Ⅰ)and one donor-acceptor complex(Ⅱ),have been reported in the previous paper.Based on theab initio 6-31G basis set calculations,the properties of the charge density for the complexeshave beenanalyzed using the theory of atoms in molecules.The nature of the complex formation has beendiscussed in terms of the properties of the charge density distributions.     

A STUDY ON THE STRUCTURE AND PROPERTIES OF POLYBUTYLALDEHYDE FORMED IN LOW TEMPERATURE PLASMA

The polybutylaldehyde obtained by plasma polymerization was investigated by means of IR, X-ray diffraction, GC-MS, elementary analysis, TEM, electron diffraction and contact angle measurements etc. The results showed that the polymer formed in plasma is amorphous crosslinked polymer, and its backbone is made of carbon atoms. The surface energy of the polymer film is independent of the polymerization conditions. No addition reaction has taken place in the carbonyl group of butylaldehyde in the plasma condition. The result of the wettability measurements showed that the polymer film is generally hydrophobic and the surface energy of the film is about 41 dyn/cm, in which the dispersion force contribution is the majority. The electron diffraction proved that some crystal substance, even the single crystals were present in the polymer. X-ray diffraction also proved the presence of crystal and showed about 15% crystaUinity fraction.     

STUDY ON PHOTO-INDUCED ORIENTATION OF A NOVEL PHOTO-ALIGNMENT FILM WITH SURFACE ENHANCED RAMAN SCATTERING （SERS） SPECTROSCOPY

Surface enhanced Raman scattering (SERS) spectroscopy was first utilized to study the photo-orientation behaviour of the photoreactive groups on a novel photo-alignment film surface and elucidate the generation mechanism of pretilt angle. The novel photo-alignment film was prepared by spin-coating a solution of ladderlike polysiloxane (LPS) bearing dual photoreactive group on an ITO surface and by irradiation with linear-polarized ultraviolet (LPUV) light. A Si-H terminal compound (M) containing an identical photosensitive part has been used to fabricate a model film for SERS investigation.     

A STUDY ON VOLTAMMETRIC BEHAVIOR OF INDIGO CARMINE AND ITS MIXTURE WITH AMARANTH AT MERCURY FILM ELECTRODE ON SILVER SUBSTRATE

The voltammetric behavior of indigo carmine at mercury film electrode on a silver substrate (MFES) was studied in this paper. It was found that indigo carmine gave a sensitive reduction peak at a potential (Vp) of -0.11 V at pH 4.0 in aqueous solution. The MFES gave good reproducibility and life time. The peak currents (ip) depended lipearly on the concentrations of indigo carmine free 0 to 100 ng/ml.The Vp and Ip of indigo carmine at MFES were independent of the concentrations of amaranth at pH 4.0, the Vp of amaranth was -0.24 V at this pH. The differences of Vp between both colorants enabled to distinguish indigo carmine free amaranth.

This paper is the Part Ⅱ of studying the budget of kinetic energy of the typhoon No. 7507, with the emphasis on the conversion between the kinetic energy of the divergent winds and that of the non-divergent winds, and its relationship to the heating field. The main findings have been brought out as follows.     

A PRELIMINARY STUDY ON THE PERIODS OF COASTAL ELEVATION AND SUBSIDENCE ALONG THE SOUTHEAST COAST OF CHINA IN THE PAST 5000 YEARS OR MORE

The amplitude and the rate of coastal elevation and subsidence and the regularities of positive andnegative crustal movements are discussed emphatically in this paper, and on this basis 11 periods ofcoastal elevation and subsidence are distinguished. Each period is further subdivided into two stagesof subsidence-sedimentation and elevation-sedimentary hiatus; each stage covers a time interval of about250 years, that is to say, each period is equivalent to about 500 years. It is a new subject to study the period of recent coastal elevation and subsidence. For this signifi-cant but difficult subject, there have always been two distinctly different schools of thought relatingto the rate of coastal elevation and subsidence, the time division of sediments and the origin of highbeach rocks. Therefore, the authors welcome the valuable comments or criticisms on this paper fromspecialists and scholars.

In addition, at 15℃, under otherwise the same conditions, activity on catalytic reduction of C_2H_2 for different constituent systems from (NH_4)_2MoS_4 and FeCl_3 has also been determined.     

STUDY ON THE CONCENTRATION EFFECTS IN GPC IV A NEW METHOD FOR DETERMINATION OF SECOND VIRIAL COEFFICIENTS FROM THE CONCENTRATION EFFECTS

In this paper a new relation between the second virial coefficients A_2, (?)_w and (dV_(es)/dC)_c→0=K_s was derived from proposed model theory of concentration effects in GPC for mono-and poly-dispersed polymers. Based on this relation a new method for determination of second vifial coefficients from the combination of (dV_(es)/dC)_c→0=K_3, (?)_w and K_H measurements was proposed.The values of A_2 for mono-and poly-dispersed polystyrenes with molecular weight range from 10~4 to 10~6 in good and theta solvents were determined by proposed method. Results show that their values of A_2 are in agreement with those obtained by light scattering.     

A FINITE DIFFERENCE-LEAST SQUARE TECHNIQUE FOR SOLVING TIDAL WAVE EQUATIONS WITH SPECIFIC APPLICATION TO THE MODELING OF M_2 TIDE IN THE HUANGHAI SEA

It is pointed out in this paper that the information usually available is not fully utilized in the traditional methods of tidal numerical computions. The governing equations, the essential and natural boundary conditions and the empirical data are incorporated in tho present model to form an overdetermined problem. A finite difference-least square technique is proposed to solve the problem. The application to modeling the M_2 tide in the Huanghai Sea(Yellow Sea) shows the advantages of the technique.
