A novel[2]pseudorotaxane of cucurbit[6]uril(CB[6])and 1-butyl-3-methyl-imidazolium bromide([C4mim]Br)was synthesized by directly mixing the host and the guest molecules in non-aqueous *** characteri-zations of the[2]pseudorotaxane were carried out by 1D,2D NMR and X-ray crystallography techniques both in solution and in crystal *** crystal structure demonstrated that CB[6]and[C4mim]Br formed a complex with the ratio 1∶1,in which one guest[C4mim]Br was included inside the CB[6],while two other[C4mim]Br molecules were free and surrounded the[2]pseudorotaxane as solvent molecules,which could stabilize the crystal structure through hydrogen ***,parallel solvent channels consisting by free[C4mim]Br molecules occupied the pores among the frame of the pseudorotaxanes and formed zigzag lines in the crystal structure.[C4mim]Br can serve as not only the guest reactant but also the solvent in the formation of[2]pseudorotaxane for-mation.

In view of the effect of fissure water in fractured rock mass on the strength of rock mass in engineering projects, we pre-pared specimens of cement mortar to simulate saturated rock mass with continuous fractures of different slope angles. By exerting static and dynamic loads on the specimens, the mechanical characteristics of rock mass with fissure water under these loads can be analyzed. Our experimental results indicate that the static compressive strength of saturated fractured rock mass is related to the slope angle. The lowest compressive strength of fractured rock mass occurs when the slope angle is 45°, while the highest strength occurs when the specimen has no fractures. Fissure water can weaken the strength of rock mass. The softening coefficient does not vary with the slope angle and type of load. The hydrodynamic pressure of fractured rock mass gradually increases with an increase in dynamic load. For a 0° slope angle, the hydrodynamic pressure reaches its highest level. When the slope angle is 90°, the hydro-dynamic pressure is the lowest.

本试验旨探究育王期间添加不同硒源(亚硒酸钠、纳米石墨硒和纳米碳粉硒)对西方蜜蜂蜂王抗氧化、免疫指标及抗氧化、繁殖相关基因表达的影响。控制西方蜜蜂蜂王产卵后,幼虫孵化至24 h后移虫育王,将120只蜂王随机分为4组,每组30只王台。亚硒酸钠组(SSe组)、纳米石墨硒组(GSSe组)和纳米碳粉硒组(TSSe组)分别添加等量3种不同硒源(硒浓度均为3.2 mg/L),在2、3和4日龄的同一时段,从蜂群中取出3组育王框,分别在王台中人工添加5μL亚硒酸钠溶液、纳米石墨硒溶液和纳米碳粉硒溶液;对照组在王台中人工添加5μL双蒸水。待4组蜂王出房后取全虫测定抗氧化和免疫指标,解剖卵巢测定抗氧化和繁殖相关基因的相对表达量。结果表明:1)各组之间蜂王体重、翅长、体长、胸长和胸宽无显著差异(P>0.05)。2)SSe组的蜂王总超氧化物歧化酶(T-SOD)和谷胱甘肽过氧化酶(GSH-Px)活性显著高于其余3组(P<0.05),TSSe组的蜂王总抗氧化能力(T-AOC)显著高于其余3组(P<0.05),SSe组和GSSe组的蜂王酚氧化酶(PO)活性显著高于CON组(P<0.05)。3)SSe组、GSSe组和TSSe组的蜂王卵巢UDP-葡萄糖醛酸基转移酶2A3、UDP-葡萄糖醛酸基转移酶2B18和全反式视黄醇脱氢酶基因相对表达量均显著高于CON组(P<0.05)。4)SSe组的蜂王卵巢苯丙氨酸-4氢化酶基因相对表达量显著高于CON组(P<0.05),TSSe组的蜂王卵巢法尼基二磷酸磷酸酶基因相对表达量显著高于CON组(P<0.05),SSe组、GSSe组和TSSe组的蜂王卵巢法尼苏酸甲酯环氧化物酶基因相对表达量均显著高于CON组(P<0.05)。综上所述,不同硒源可提升蜂王体内抗氧化酶活性及其相关基因的相对表达量,促进蜂王的卵巢发育,提升繁殖能力,并对免疫能力具有一定的促进作用。
