简介:摘要院采用Origin软件研究了惯性称和弹簧振子的振动周期T2和质量m的关系以及不同形状的弹簧修正系数C的关系。通过Origin软件拟合可以得到符合实验要求的光滑曲线,使得实验结果处理更加直观和简便。实验结果表明,弹簧的修正系数C和弹簧的形状有关,不具有普适性。
简介:本文介绍了用Origin8。0软件对太阳能电池伏安特性测试数据进行绘图,计算平均数和标准方差的方法,说明在大学物理实验教学中引入Origin8。0软件处理数据能大大提高教学效果。

简介:从一个锰小瘤的层从菲律宾的海挖出(16°56′N,129°48′E;水深度,5700m)并且45个体积小瘤从近海Minami-Torishima岛,日本(23°3′N,153°22′E;水深度,1200m)化学上被分析,他们的起源基于geochemical限制被讨论。一般来说,,Cu,Ni,Zn和瞬间趋于与增加Mn内容增加元素(REE)少些显示出的公司,Pb,Ba,V,Sc,Th,和稀土元素有增加Mn内容的变化。来自菲律宾的海的小瘤42H有平均Mn/Fe比率结束到1并且显示出一个积极Ce异例,建议占优势的氢的起源。230Th前和230Th前/232在小瘤42H的外部∼0.3公里的Th比率显示∼1.7mm/Myr的稳定的生长率。小瘤E30从近海Minami-Torishima被更低的Mn,Fe,Mn/Fe(0.53)和Mo/V(0.2)比率描绘但是更高的P和Cu/Ni(0.31)相对来自那个区域的另外的小瘤的比率。E30的Ce内容是不平常地低的(82ppm)什么时候与来自区域和它的另外的小瘤相比是唯一的小瘤,与一个否定Ce异例(−0.64)分析了。把那个大多数基于我们建议的geochemical数据小瘤从近海除了E30,Minami-Torishima主要具有氢的起源,它被热水的输入,和E45统治,它关于35%热水的贡献有。
简介:采用5水平Box-Behnken设计的反应表面方法论(RSM)被用来优化铈(III)的biosorption到动物和植物起源viz的biowaste材料上。对虾甲壳(PC)和玉米风格(CS)。各种各样的过程参数viz。pH(一:3.0–9.0),生物资源剂量(B:0.05–0.35g/L),起始的金属集中(C:50–350mg/L),接触时间(D:2–6h)并且温度(E:20–60°C)为优化被选择。木头转变被盒子艇长阴谋在现在的盒子中建议。低p值<0.0001验证了模型的意义。为PC的218.3mg/g和为CS的180.2mg/g的最大的Ce(III)举起在最佳条件下面被注意。在平衡等温线之中,Freundlich模型被发现是而兰米尔模型证明最好适合在CS上建议铈biosorption的同类的模式,在PC上建议biosorption的一个异构的模式的最好适合的那个。这被扫描电子显微镜学(SEM)进一步证实。运动研究显示出作为位于这个过程下面的现象建议physisorption的伪first顺序模型的更好的适用性。电影散开被博伊德阴谋的非线性建议。热力学的研究证明这个过程吸热、自发。FTIR分析在Ce(III)biosorption期间证实了酰胺,胺,酉同类和主要白酒组的参予的主要参与。EDAX分析在Ce(III)biosorption期间证实了碳组的主要参予。这是Ce(III)biosorption的参数优化上的第一份报告到用可能从水的环境对Ce(III)的恢复有用的5水平Box-Behnken试验性的设计的biowaste材料上。
