早期的裂谷作用深刻影响后续伸展过程中岩石圈的变形行为,控制叠合盆地的发育过程。澳大利亚西北被动大陆边缘经历了晚古生代超伸展(hyperextension)裂谷作用和中生代窄裂谷作用(narrow rifting),为典型的复合型被动大陆边缘。高精度2D/3D深地震反射数据为深入研究澳大利亚西北陆缘晚古生代-中生代的多期、多种变形模式裂谷作用叠合过程提供了重要条件。

周期性负载变化提高乙醇燃料电池效率(英文)

催化学报 2015年第4期36卷 496-501页

We present a simple method to increase the efficiency of a direct ethanol fuel cell by a periodic modulation of the load(pulsed mode). The fuel cell was periodically short circuited with a resistor(1 Ω) for a few seconds(high load period) followed by a low load period of up to 100 s when the resistor was disconnected. The open circuit voltage(OCV) values before and after the short circuit of the cell showed an increase of up to 70 mV. The higher OCV was due to the oxidation and removal of strongly adsorbed CO during the electric short circuit when the electric potential of the anode was increased to be close to the cathode potential. The depoisoned anode surface was much more active directly after the short circuit. The slow decrease of the OCV observed after the short circuit was caused by the subsequent poisoning of the anode surface, which can be neutralized by another short circuit. In general, a stable increase in cell performance was obtained by repetition of the electric short circuit. The data showed that the pulse mode gave an increase in the power generated by the direct ethanol fuel cell by up to 51% and was 6% on average. It is anticipated that this mode of operation can be used also in different types of polymer electrolyte membrane fuel cells where CO poisoning is a problem, and after optimization of the parameters, a much higher gain in efficien-cy can be obtained.

文章利用14副成年金丝猴骨架(包括滇金丝猴Rhinopithecus bieti;黔金丝猴***)对其长骨与体重间的异速生长进行了分析研究。结果表明,在金丝猴的生长发育过程中,前肢的生长速度大于后肢。这种形态特征与金丝猴在运动过程中攀爬垂直支撑物相联系。从肢间指数和生长系数看,金丝猴的前后肢与其它灵长类相比较,相对于体重来说比较短。这是在树上攀缘过程中使重心更接近支撑攀物和使身体稳定的一种适应。对躯干长(STL),肱骨、桡骨、股骨和胫骨经多维变量分析说明了金丝猴的长骨与体重之间的关系,长骨的结构特征与狮尾狒(Theropithecus)、狒狒(Papio)、叶猴(Presbytis)、猕猴(Mcaaca)及长鼻猴(Nasalis)更为接近。在金丝猴的运动特征上,我们据此推测,它们有一部分时间在地上活动,但休息、睡觉、寻食及逃避敌害等时在树上。因此,在运动中,跳跃、臂摆荡和悬吊不是它们的主要运动方式。
