The el.mentary mechanis.ic model.of ads.rption and s.rption is.bas.d on a s.mpl. hypothes.s. the ads.rption s.tes.are uniforml. dis.nbuted on the s.rface of the pore wal.s.in the ads.rbent, the s.rption s.tes.are uniforml. dis.ributed in the vol.me of the pol.mer. In this.firs. paper we wil. anal.ze the s.mpl. cas. where one s.l.te mol.cul. is.onl. al.owed to occupy a s.ngl. ads.rption or s.rption s.te. A common el.mentary occupation l.w of the free s.tes.is.as.umed： the differential.increas. of the number of the ads.rbed/s.rbed mol.cul.s.is.proportional.to the differential.increas. of the activity of the s.l.te and the concentration of the free （non-occupied） s.tes.in the s.l.d. The proportional.ty coefficient is.cal.ed affinity coefficient depending on the s.l.d/s.l.te coupl. and on the temperature and independent of the concentration of the s.l.te. In ads.rption the concentration of the free s.tes.is.a s.rface concentration on the pore wal.s.and in s.rption it is.expres.ed by the mol.rity. The s.mpl. monol.yer ads.rption l.w of Jovanovic is.obtained： n = no（1 - e KP） where n is.the number of mol.s.ads.rbed when the pres.ure is.P. no is.the total.number of ads.rption s.tes.and K the affinity coefficient for ads.rption. The s.rption l.w writes. a = 1/k [Ф/1-Ф] ＋ 1-r/k In [1 ＋ 1/r Ф/1-Ф] where Ф, r and k hol. res.ectivel. for the vol.me fraction of the s.l.ent in the pol.mer, for the ratio of the mol.r vol.mes.of the s.l.ent to the el.mentary pol.mer chain containing one s.ngl. ads.rption s.te and for the s.rption affinity coefficient. The confrontation of thes. equations.to experimental.is.therms.is.s.tis.actory in comparis.n with the cl.s.ical.l.ngmuir and Fl.ry-Huggins.equations. the bes. res.l.s.are obtained for ads.rption of vapors.on a 5A zeol.te and for al. anal.zed s.rption res.l.s.

In Gao’s.previous.work, the authors.determined s.veral.degree conditions.of a graph which admits.fractional.factor in particul.r s.ttings. It was.reveal.d that thes. degree conditions.are tight if b = f(x) = g(x) = a for al. vertices.x in G. In this.paper, we continue to dis.us. thes. degree conditions.for admitting fractional.factor in the s.tting that s.veral.vertices.and edges.are removed and there is.a difference Δ between g(x) and f(x) for every vertex x in G. Thes. obtained new degree conditions.reformul.te Gao’s.previous.concl.s.ons. and s.ow how Δ acts.in the res.l.s. Furthermore,counterexampl.s.are s.ructured to reveal.the s.arpnes. of degree conditions.in the s.tting f(x) =g(x) + Δ.

目的采用听神经同步专利刺激声(CE-Chirp声)对成人听性脑干反应(auditory brains.em res.ons.,ABR)进行测试,分析CE-Chirp ABR测试的V波反应阈与纯音听阈的关系,研究CE-Chirp声在法医学鉴定听觉功能障碍评估中的作用。方法选择常州市德安医院2018年1月—2019年6月进行CE-Chirp ABR测试的受试者(年龄为20~77周岁,共计100耳),获得V波反应阈值,并在0.5、1.0、2.0、4.0 kHz分别进行纯音气导听阈测试,获得纯音听阈值,按照不同听力水平及不同年龄对受试者进行分组。比较不同听力水平及不同年龄组平均纯音听阈与V波反应阈之间的差值及统计学差异;对所有受试者各频率两种方法之间的相关性、差值及统计学差异进行分析;建立所有受试者CE-Chirp ABR V波反应阈推断纯音听阈的线性回归方程,并检验其推断纯音听阈的可行性。结果不同听力水平及不同年龄组各组之间CE-Chirp ABR反应阈与纯音听阈差值的差异无统计学意义(P>0.05);各频率成人CE-Chirp ABR V波反应阈与纯音听阈之间相关性良好,两者之间差异具有统计学意义(P<0.05),线性回归分析显示两者之间有线性相关关系(P<0.05)。结论运用CE-Chirp ABR Ⅴ波反应阈在一定条件下能够评估受试者的纯音听阈,可以作为一种听力学测试方法用于法医学听觉障碍评估。
