| 1 | Preliminary research on Megalake Jilantai-Hetao in the arid areas of China during the Late Quaternary显示文摘我们识别了 geomorphological,在通过地调查并且通过地区性的遥感的分析的当前的 Jilantai 盐湖附近的高湖层次的沉积、生物的证据想象。在约 1060, 1050, 1044 和 1035 m a.s.l 的举起有四组海岸线,是在当前的盐湖上面的 37, 27, 21 和 12 m 分别地出现。沙和石子的沿岸的存款在在 1070 和 1080 m a.s.l 之间的举起被发现,比水流高的 47 ~ 57 m 腌湖表面,尽管 palaeoshoreline 地形仅仅在几个地点被保存。在 Herimuxini,在 Ulan Buh 荒芜的、典型湖的沉积和沙石子的北边缘上,沿岸的存款也发生在 1080 m a.s.l 并且在下面的举起。典型吐痰扩大的 A 11-km-long 从逐渐地在它的大拐弯上沿着黄河的南部的银行在一些沙石子石场从 1050 ~ 1035 m a.s.l 在举起减少的这条海岸线东方海岸线特征例如在水文学计量器车站和 Shilazhao 镇附近定位的那些,被识别。沿岸的存款 overlying 冲积的洪水的层在 Hangjin 在 Balagong 附近发生在沙石场县。也有沙滩岩石和沿岸的存款,沿着 Langshan-Yinshan 山的南部的山麓在几个地点在 cut-and-built 平台上保存。另外,揭示水下的三角洲沉积的侧面在 Wuhai 附近被识别,在黄河进入盆的地方。典型的湖沉积也在 Hetao 平原的东方结束在 Togtoh 站台存在。水的软体动物壳在沿岸的存款是普通的,包括 Corbicula 的几种,根值 lagotis, R。xauricularia 和 Gyraulus convexiusculus。Ostracode 壳能也在更好的沉积被识别。典型垂直 prograding 序列在湖的沉积很好被保存的露头是明显的。滚动波浪的卵石和沙滩岩石很通常在更高的举起在堤在侧面的顶上被保存。所有这些证据建议曾经有一个巨大的palaeo湖,用到达我们指的 ∼1080 m a.s.l 的最高的湖水平盖住 Jilantai 区域和 Hetao 平原的大多数部分巨大的 paleolake ,比现代的湖贝加尔湖大,作为“ Megalake Jilantai-Hetao ”. OSL 标明日期结果显示大湖以前形成了 ∼60 —50 ka,和在在 1060 和 1035 m a.s.l 之间的举起的四条海岸线多半从 ∼60 ∼50 ka 代表湖水平变化到早 Holocene。Megalake Jilantai-Hetao 的发现将多半影响黄河的发展的理解在期间晚第四级, Ulan Buh 和 Kubq 的进化抛弃,在这个区域的 neotectonism,并且可能地区性的气候的变化。 | CHEN FaHu FAN YuXin CHUN Xi D.B.

| 2 | INVESTIGATION OF SURFACE MORPHOLOGY, STRUCTURE AND ELECTROCATALYTIC PROPERTIES FOR O_2 EVOLUTION OF TITANIUM BASED IrO_2+Ta_2O_5 COATINGS显示文摘Titanium based IrO2 +Ta2O5 oxide anodes with different compositions and pyrolysis temperatures were prepared by termodecompoisition method. By using X-ray diffraction (XRD), the structure and texture coefficient of the coatings, TC(hkl), of IrO2 rutile crystal have been tested. It showed that, the crystallization processes of IrO2 and Ta2O5 in xIrO2 +(100-x) Ta2 O5 (x is in mol%) films affected and confined each other.In the mixed system, IrO2 rutile phase existed as a solid solution with Ta, and attained the maximum solubility when x=70mol%, i.e. for the coating of 70% IrO2 +Ta2O5.For the coatings of low iridium content or at low preparing tem pemture, (110) and (101) pwtered orientations were dominant. However, preferred growth of IrO2 weakened with increasing either iridium content or temperature. Three typical surface morphologies were observed by using scanning electron tnicroscopy(SEM). The crystallite size of the mixed oxide coatings were finest for the the film of 70%IrO2 +30%Ta2O5,and decreased with the pyrolysis tempemture. As the results of the finest crystallite segregating on sudece and the maxitnum solid solubility of Ir and Ta component in deposits, the coatings with the composition of 70%IrO2 +Ta2O5 prepared at 450℃ presented the mdrimutn electrocatalgtic activitg for O2 evolution in 0. 5M H2SO4 solution.UP to 550℃, Ti base suffered to oxidation resulting in decreasing anode conductivity,therefore, coatings performed a low activity. | J.M Hu J.X.

| 3 | EFFECT OF SnO_2 ADDITION ON THE SERVICE LIFE AND ELECTROCHEMICAL PROPERTIES OF Ti/IrO_2,+Ta_2O_5 ANODES IN PHENOLSULFONIC ACID SOLUTION显示文摘Service life of two different oxide anodes in phenolsulfonic acid (PSA) solution was investigated by accelerated electrolysis. The durability of Ti/IrO2+Ta2 O5 anode increased by the addition of SnO2 in the mixed oxides. The degradation mechanisms of Ti/IrO2+ Ta2 O5 and Ti/IrO2 +Ta2 O5 +SnO+2 anodes were different. It was shown from the observation of scanning electron microscopy (SEM) and the electrochcmical measurement that, the deactivation of Ti/IrO2 + Ta2 O5 anode was due to the build-up of an organic film on surface. The growth of the covered film on surface was restricted by addition of SnO2, which resulted in increasing of the service life of anodes. The over-potential for oxygen evolution on Ti/IrO2 +Ta2 O5 electrode increased after doping SnO2, and the intermediate products of PSA building-up on the surface was much more rapidly oxidized. Meanwhile, a certain part of the surface oxide deposit entered into the solution leading to loss of oxides, which resulted in degradation of Ti/IroO2 + Ta2 O5 anode containing SnO2 component. | J.M.
