The Carboniferous volcanic rocks in the Wulungu-Luliang area are mainly andesites of medium- to high-K calc-alkalic series. Volcanic rock samples have relatively high alkali(Na2O + K2 O = 4.7 % to 6.8 %) and low Ti O2contents(0.7 % to 0.9 %), relatively high Mg O(2.5 % to 3.4 %) and Mg#(49.9 % to 67.1 %), high rare earth element(REE) contents, and relatively high K2 O contents(1.7 % to 3.1 %). Chondrite-normalized REE patterns show light REE enrichment((La/Yb)N= 4.15 to 5.19)with weak Eu anomalies(d Eu = 0.75 to 0.92). These samples are enriched in large-ion lithophile elements but relatively depleted in high field strength elements. The trace elements and REE patterns are similar to those of Setouchi and central Ryukyu high-Mg andesites, indicating a highMg andesite source. Relatively high Y contents(16.7 to24.4 ppm), and relatively low Sr/Y ratios(17.2 to 38.8) and Ti O2contents(0.7 % to 0.9 %) exclude the possibility of slab melting. Low Sr/Nd(16.6 to 42.8), Ba/Th(66.4 to266.8), and U/Th(0.2 to 0.3) indicate that the influence of slab-derived fluids is low. The ratios of Ce/Th(4.9–7.3), Ce/Pb(1.8–4.2), Ba/Rb(7.99–22.03), Ba/Th(66.4–266.8), and La/Sm(3.6–4.3) are similar to ratios found in subducting sediment melts. Relatively high ratios of K/Nb(1357–3258),Th/La(0.28–0.42), Zr/Nb(8.8–27.1), and especially Th/Nb(0.48–1.25) suggest that the magma was assimilated and contaminated by upper continental crust. These characteristics, along with the ratios of La/Yb, Sc/Ni, Th/Yb, Ta/Yb,Ce/P2O5, and Zr/Ti O2, demonstrate that the earlier Carboniferous volcanic rocks in the Wulungu-Luliang area were generated in a continental island-arc setting.

In this study, poly（L-lactic acid）/ammonium persulfate doped-polypyrrole composite fibrous scaffolds with moderate conductivity were produced by combining electrospinning with in situ polymerization. PC12 cells were cultured on these fibrous scaffolds and their growth following electrical stimulation （0-20.0 μA stimulus intensity, for 1-4 days） was observed using inverted light microscopy, and scanning electron microscopy coupled with the MTT cell viability test. The results demonstrated that the poly（L-lactic acid）/ammonium persulfate doped-polypyrrole fibrous scaffold was a dual multi-porous micro/nano fibrous scaffold. An electrical stimulation with a current intensity 5.0- 10.0 μAfor about 2 days enhanced neuronal growth and neurite outgrowth, while a high current intensity （over 15.0 μA） suppressed them. These results indicate that electrical stimulation with a moderate current intensity for an optimum time frame can promote neuronal growth and neurite outgrowth in an intensity- and time-dependent manner.

In the history of human space exploration, many failures of launch vehicles and spacecraft tare caused by vibration. At first, the periods in which the space products are in a vibration environment are discussed and the need for vibration testing is then introduced. As the main content of this paper, the current situation of shaker systems is elaborated in detail. In this part, electrodynamic shakers, as the most widely used vibration generators, are illustrated in detail including structures, principles and performances. Special inventions worldwide in the development of electrodynamic shakers such as induction ring shakers, high force shakers, multi-axial vibration testing systems and combined environmental testing systems are presented.

采用离子交换法将不同季铵盐插层到钠基蒙脱土中制备了改性蒙脱土。改性蒙脱土对革兰氏阳性菌(***)和革兰氏阴性菌(***)均有很强的抗菌作用,并且随着季铵盐在蒙脱土中的质量分数增加其抗菌活性增强。不同季铵盐改性蒙脱土的抗菌活性不同,其中双季铵盐改性蒙脱土的抗菌活性最好,对***和***的最小抑菌浓度分别为6.25mg/L和12.5mg/L。用扫描电镜对与细菌接触不同时间后的改性蒙脱土进行观察,结果表明:细菌先吸附到改性蒙脱土的表面,然后慢慢的变形死亡。同时,对在0.9%的生理盐水中浸泡不同时间后的改性蒙脱土进行X射线衍射和热重分析。结果表明:随着浸泡时间的增加,蒙脱土中的有机物质量分数及层间距均逐渐减少,说明季铵盐能从蒙脱土的层间解吸出来,并进入溶液中直接杀死细菌。因而,改性蒙脱土的抗菌活性是吸附与释放到溶液中的季铵盐离子协同作用的结果。

车排子-莫索湾古隆起是准噶尔盆地腹部的正向构造单元,油气成藏条件优越,其形成演化过程对于挤压环境下“凹中隆”格局的变形史有较大的指示意义。本文通过区域构造分析和地震资料精细解释明确了车排子-莫索湾古隆起的构造特征及演化过程,通过砂箱实验模拟揭示了古隆起的成因机制。研究结果表明,古隆起以古潜山形式存在于盆地腹部,在白垩系沉积前为轴向NE-SW的宽缓背斜,脊线高点位于征1井附近,南北两端弯曲,整体成“S”形。古隆起的演化可分为四个阶段:中侏罗世前的基底调整稳定期;中侏罗世在西北缘边界挤压下盆地腹部缓慢隆升雏形期;晚侏罗世古隆起快速隆升形成期;白垩纪-新生代受盆地南缘控制整体南倾改造期。受中、晚侏罗世达尔布特断裂左行走滑作用影响,扎伊尔山系派生SE向挤压应力导致的远程传递作用使盆地腹部发育平缓的背斜,隆起轴线与西北缘断阶带走向近平行;乌伦古地块南界的右行剪切作用使得古隆起轴线向北东弯曲,盆地边界形态及南缘挤压剪切造成古隆起上升并转向。古隆起在油气成藏过程中具有较好的聚油作用,尽管后期形态改造造成了原有油气藏部分被破坏,但也导致油气向北西运移并聚集。本文研究认为,该地区今后的油气勘探方向应以岩性及构造-岩性复合油气藏为主。
