To fully display the modeling mechanism of the novelfractional order grey model （FGM （q,1））, this paper decomposesthe data matrix of the model into the mean generation matrix, theaccumulative generation matrix and the raw data matrix, whichare consistent with the fractional order accumulative grey model（FAGM （1,1））. Following this, this paper decomposes the accumulativedata difference matrix into the accumulative generationmatrix, the q-order reductive accumulative matrix and the rawdata matrix, and then combines the least square method, findingthat the differential order affects the model parameters only byaffecting the formation of differential sequences. This paper thensummarizes matrix decomposition of some special sequences,such as the sequence generated by the strengthening and weakeningoperators, the jumping sequence, and the non-equidistancesequence. Finally, this paper expresses the influences of the rawdata transformation, the accumulation sequence transformation,and the differential matrix transformation on the model parametersas matrices, and takes the non-equidistance sequence as an exampleto show the modeling mechanism.

煤储层渗透率受自身性质、温度、应力状态等诸多因素影响。以淮南刘庄煤矿13-1煤层为研究对象,基于CH_(4)渗透率测试,研究了体积应力、温度与气体压力耦合以及循环围压下CH_(4)渗透率的变化规律。结果表明:体积应力与气体压力耦合主要通过控制有效应力大小来影响煤岩CH_(4)渗透率,有效应力越大,渗透率越低;气体压力对CH_(4)渗透率的影响受限于体积应力,但气体压力对渗透率的影响大于体积应力;温度与气体压力耦合对CH_(4)渗透率的影响由气体压力主导,渗透率随气体压力的增大呈“U形滑梯式”下降,且“滑梯式”变化比“U”形变化更为明显;气体压力对CH_(4)渗透率的影响大于温度,且增大气体压力会降低温度对渗透率的影响;循环围压会造成煤岩孔裂隙的不可逆塑性变形,使煤中有效渗流通道减少,CH_(4)渗透率降低;第1次循环围压产生的塑性变形量最大,随循环次数增加,塑性变形量逐渐减少。

The hyphal development of Candida albicans(***) has been considered as an essential virulent factor for host cell ***, the missing link between hyphae and virulence of *** is also been discovered. Here, we identified that the null mutants of ERG3 and ERG11, two key genes in ergosterol biosynthesis pathway, can form typical hyphae but failed to cause the oral mucosal infection in vitro and in vivo for the first time. In particular, the erg3Δ/Δ and erg11Δ/Δ strains co-cultured with epithelial cells significantly reduced the adhesion, damage, and cytokine(interleukin-1α(IL-1α)) production, whereas the invasion was not affected in vitro. Importantly, they were incapable of extensive hyphal invasion, formation of micro-abscesses, and tongue epithelium damage compared to wild type due to the decrease of the colonization and epithelial infection area in a murine oropharyngeal candidiasis model. The fluconazole(FLC), an antifungal targeted at ergosterol biosynthesis, relieved the epithelial infection of *** vitro and in vivo even under non-growth inhibitory dosage confirming the virulent contribution of ergosterol biosynthesis pathway. The erg3Δ/Δ and erg11Δ/Δ strains were cleared by macrophages similar to wild type, whereas their virulence factors including agglutinin-like sequence 1(Als1), secreted aspartyl proteinase 6(Sap6), and hyphal wall protein-1(Hwp1) were significantly reduced indicated that the non-toxicity might not result from the change on immune tolerance but the defective virulence. The incapacity of erg3Δ/Δ and erg11Δ/Δ in epithelial infection highlights the contribution of ergosterol biosynthesis pathway to *** pathogenesis and fluconazole can not only eliminate the fungal pathogens but also reduced their virulence even at low dosage.
