Six sterically hindered chloro meso-tetra-ortho-alkylphenylporphinato irons (T(o-R)PPFe(III)Cl, R = Me, Et, n-Pr, i-Pr, n-Bu, t-Bu) were synthesized and used to catalyze the monooxygenation of cyclohexane with PhIO. Both the yields of cyclohexanol and the relative rates of monooxygenation of cyclohexane catalyzed by T(o-R) PPFe(IIl)Cl were higher than those of TPPFe(III)Cl respectively. The order of the yields(%) of cyclohexanol and the rate of cyclohexanol formation in the monooxygenation of cyclohexane catalyzed by T(o-R)PPFe(III)Cl for the different substituents are: i-Pr(58) > Et(57) > n-Pr(52) > Me(51) > n-Bu(48) > t-Bu(46) > H(35) and i-Pr > Et > t-Bu > n-PT greater than or equal to Me greater than or equal to n-Bu greater than or equal to H respectively. The special steric effect on the catalytic character of these different alkyl substituents in T(o-R)PPFe(III)Cl is proposed on the basis of the results.

The effects of pigment glands and gossypol on the somatic cell culture of upland cotton were studied, using the materials as follows: three pairs of glanded and gland less upland cotton near isogenic lines, TM-1, and Coker 312. The results showed that the pigment glands and gossypol contents in the explants had great inhibiting effect on the induction and growth of callus in somatic cell culture of upland cotton, and the induction rate of callus and the single callus weight of glandless cotton were much higher than those of their glanded near isogenic lines. It was easier to obtain regeneration plants from glandless cotton than from their glandednear isogenic lines. There was a significant inverse correlation between the gossypol contents in the explants and callus induction rate, with the correlation coefficient of -0.84. The vitro gossypol in the medium had some inhibiting effect on the induction and growth of callus, especially for the gland-less cotton. However, a certain concentration of vitro

The investigation of the system BaF2-WO3 revealed the existence of a fluoro-tungstate formulated as Ba2WO3F4. The Ba2WO3F4 was prepared with the solid state reaction method. Under UV or X-ray excitation, Ba2WO3F4 exhibits a very strong blue-green emission peaking at 480 nm at room temperature. The luminescence properties are similar to those of the tungstate, especially MgWO4. The luminescence and energy transfer of tungstates are well known for a long time and was reviewed by Blasse([1]). But barium tungstate show only weak luminescence even down to liquid helium temperature([2]). We were surprised to find that Ba2WO3F4 is an efficient phosphor which can be practically used. In this paper, the preparation method and luminescence properties of Ba2WO3F4 phosphor were investigated. The relationship between the luminescent properties and crystal structure was discussed.

Kevlar-49 fiber was modified through cold air plasma treatment and plasma grafting with acrylic monomers. Fracture of aramid fiber/epoxy resin micro composites has been studied by means of single fiber pull-out test. Tow types of pull-out curves are correlated with the different failure modes. A polyacrylic acid-co-ethyl acrylate graft layer can improve the adhesion and protect the fiber from damage caused by interfacial stresses.

In this paper, the dynamic response of undersea -+towed systems is numerically simulated. A two body towed system is especially considered in detail. The factors influencing the heave of towed-bodies, such as the weight of the towed-body (in sea water), the length and the weight (in sea water) per unit length of the cable between towed-bodies and towing ship, are investigated in detail. Calculations show that the two-body towed system can greatly increases the stability of the towed system.

QUANTIZED radiation fields exhibiting nonclassical properties have been of great theoretical andexperimental interest in the last two decades. It is shown that various nonclassical states suchas squeezed state and Schrodinger cat state can be generated out of coherent state in thenonlinear process of the interaction of atom and field although the radiation field in a
