g.aphene is a sing.e atom thick crystal composed.of carbon atoms. It is the lig.test, thinnest, strong.st material that cond.cts heat and.electricity well heretofore. In terms of application, by introd.cing.oxyg.n-containing.g.oups, g.aphene can be well d.spersed.in solvents, can be chemically mod.fied.and.functionalized. or connected.with other electroactive substances throug. covalent bond.or non-covalent bond.to form composite materials, which is cond.cive to further processing.and.promotion. The application of g.aphene in oilfield.chemistry started.late, but d.veloped.rapid.y. g.aphene has played.an active role in d.illing.fluid. cementing.fluid. fracturing.fluid. d.splacement fluid.and.other oilfield.working.fluid.. It can enhance the temperature and.salt resistance of working.fluid.and.improve the effect of working.fluid. In this paper, several d.rections of g.aphene applications in oilfield.chemistry, such as mod.fied.g.aphene, g.aphene copolymers and.g.aphene nanoparticles, are reviewed.in d.tail from the synthesis method., action mechanisms and.effects of g.aphene and.its d.rivatives, and.the frontier cases at this stag. are g.ven. On the basis of the existing.research, sug.estions for the d.velopment d.rection of g.aphene materials in oilfield.chemistry are g.ven for a variety of g.aphene materials, aiming.to provid. g.id.nce for the application of g.aphene in oilfield.chemistry.

Comparative stud. on phase transition behaviors of fractional molecular field.theory and.rand.m-site Ising.mod.l

Fractional molecular field.theory(FMFT)is a phenomenolog.cal theory that d.scribes phase transitions in crystals with rand.mly d.stributed.components,such as the relaxor-ferroelectrics and.spin *** ord.r to verify the feasibility of this theory,this paper fits it to the Monte Carlo simulations of specific heat and.susceptibility versus temperature of two-d.mensional(2d.rand.m-site Ising.mod.l(2d.RSIM).The results ind.cate that the FMFT d.viates from the 2d.RSIM *** main reason for the d.viation is that the 2d.RSIM is a typical system of component rand.m d.stribution,where the real ord.r parameter is spatially heterog.neous and.has no symmetry of space translation,but the basic assumption of FMFT means that the parameter is spatially uniform and.has symmetry of space translation.

以廉价原料大豆糖蜜(soybean molasses, Sm)为试材,采用生理生化指标(生物量、菌球形态、糖代谢速度、胞外酶活力、走菌速度和出菇产量)测定比较法,研究了Sm不同添加量对斑玉蕈液体菌种质量的影响,以期为高值化利用廉价原料Sm制备斑玉蕈液体菌种提供参考依据。结果表明:Sm的适宜添加量为1%,液体培养基中添加1%Sm可以促进斑玉蕈的糖代谢速度,菌丝生长加快,培养至6 d.可达到稳定期,获得的液体菌种生物量更高,且菌球大小均一、无毛刺,菌种表观质量明显提高;液体菌种生理生化活性测定结果表明,添加Sm可以促进胞外蛋白质的分泌,培养基中木聚糖酶、纤维素酶和漆酶活力提高,尤其是漆酶,酶活力是对照的30.4倍,从而加快对Sm中酚酸类物质的降解,培养基pH快速升高,获得的斑玉蕈Sm液体菌种菌球回接后菌丝萌发快、菌丝平均生长速度比对照提高了5.3%;出菇试验表明,斑玉蕈Sm液体菌种相比对照菌丝满袋时间提早4~9 d.去头出菇产量提高6.9%。试验结果表明培养基中添加1%Sm可以缩短斑玉蕈液体菌种制种时间,且有效提高液体菌种质量。
