Pressure histories were tested in a 500-L chamber to identify the pressure load in confined explosion from aluminized explosives. Different aluminized explosives with Al/O, ranging from 0.25 to 1.23, were used. The recorded pressure curves could express the reflection of initial shock wave and the after burning combustion of aluminum. As there is no objective way to gain quasi-static pressure(P_(QS)),method of multipoint averaging was used in smoothing the original pressure curves to gain the P_(QS). The P_(QS),rising time of pressure(t_(QS)) which stands for the duration of the initial reflected shock wave, and attenuation coefficient(ω) which stands for the supportive effects of the combustion of aluminum to the P_(QS) are used to characterize the pressure load in the confined explosion from aluminized explosives. The research results showed that the Al/O significantly affected the three characteristic quantities. With the increase of Al/O, the P_(QS) increased at first and decreased later, gaining maximum at Al/O=0.99; the t_(QS)sustained growth and the ω decreased at first and increased later, gaining minimum at AI/O=0.99.

Based on the diquark model, we assume that the light scalar mesons are q^2q^-2 states rather than qq^-. The chiral effective Lagrangian for the light scalar meson is constructed, and the mass relations are obtained： the isotriplet （a0） and the isosinglet （f0） are the heaviest and are degenerate, the isodoublets （κ） are heavier and the other isosinglet （σ） is the lightest; and 2Mκ^2 = Mα0^2＋ Mσ^2. Using experimental value for a0 and σ mass, we obtain Mκ=794 MeV, which is consistent with the experimental value. Then taking Г（a0^0 →ηπ^0） = 90 MeV and Г（f0→π^0π^0） = 20 MeV, we get the width of σ is： Г（σ0→π^＋π^-）= 150 MeV.

目的:探究黄芩醇提物调节免疫平衡治疗溃疡性结肠炎(ulcerative colitis,UC)的作用及机制。方法:将24只C57BL/6小鼠随机分为正常组、模型组、美沙拉嗪组(500 mg·kg^(-1))、黄芩醇提物(400 mg·kg^(-1))组,每组6只。采用2.5%葡聚糖硫酸钠(dextran sulfate sodium,DSS)的饮用水建立UC小鼠模型。每天观察各组小鼠体重及一般情况,d 6计算疾病活动指数(DAI);测量结肠长度;采用流式细胞术检测肠系膜淋巴结和脾脏中辅助性T细胞17(T helper 17,Th17)和调节性T细胞(regulatory T cells,Treg)比例;苏木精-伊红染色观察结肠组织损伤程度;酶联免疫吸附法检测结肠白细胞介素-6(interleukin,IL-6),IL-10和IL-1β的含量;蛋白免疫印迹法检测结肠Toll样受体4(Toll-like receptor 4,TLR4)、核因子κB p65(nuclear factor-kappa B,NF-κB p65)、p-NF-κB p65及核因子κB抑制蛋白-α(I kappaB-alpha,IκB-α)的表达水平;气相色谱-质谱联用检测短链脂肪酸的含量;高内涵成像技术观察RAW264.7细胞核转位情况。结果:黄芩醇提物可改善DSS诱导的小鼠结肠炎症状,恢复肠系膜淋巴结和脾脏中Th17/Treg免疫平衡,降低结肠组织中IL-1β和IL-6水平、提高IL-10表达水平,降低TLR4,NF-κB p65和p-NF-κB p65表达水平,提高IκB-α表达水平,提高肠道短链脂肪酸含量,抑制脂多糖诱导引起的核转位。结论:黄芩醇提物可以改善UC小鼠的症状,其机制可能是通过改善肠道稳态,抑制TLR4/NF-κB通路以恢复Th17/Treg免疫平衡。

为了改善ZL114A的力学性能,采用稀土Y对机械振动下ZL114A合金进行变质处理,研究Y含量对其微观组织及力学性能的影响。结果表明,稀土Y能有效细化α-Al枝晶并促进α-Al枝晶由粗大的树枝状向蔷薇状转变,同时使共晶Si呈短棒状且均匀分布。随着Y含量增加,合金的抗拉强度、伸长率及硬度均呈先增后减的趋势。当Y含量为0.6%时,合金的二次枝晶间距最小,为20.4μm,其抗拉强度、伸长率及硬度(HV)值最大,分别为370.92 MPa、6.8%和91.08。当Y含量大于0.6%时,α-Al组织逐渐粗化,稀土相由较小的块状转变为长棒状。
