微型同位素辐射能收集器二维悬臂梁机电建模

基于欧拉-伯努利梁理论,设计了一种新型的微型同位素辐射能收集器二维机电模型。该模型解决了一维机电模型无法涵盖的诸多问题。算例分析表明:本模型能较准确地描述实验过程和预测实验结果。通过对结果进行分析,得出了影响微悬臂梁的位移、梁的往返周期和梁中存储能量的一系列因素。

With strings attached: Gift-giving to the International Atomic Energy Agency and US foreign policy

In 1958 the United States of America offered two mobile radioisotope laboratories to the International Atomic Energy Agency (IAEA) as gifts. For the USA, supplying the IAEA with gifts was not only the cost of “doing business” in the new nuclear international setting of the Cold War, but also indispensable in maintaining authority and keeping the upper hand within the IAEA and in the international regulation of nuclear energy. The transformation of a technoscientific artefact into a diplomatic gift with political strings attached for both giver and receiver, positions the lab qua gift as a critical key that simultaneously unlocks the overlapping histories of international affairs, Cold War diplomacy, and postwar nuclear science. Embracing political epistemology as my primary methodological framework and introducing the gift as a major analytic category, I emphasize the role of material objects in modeling scientific research and training in a way that is dictated by diplomatic negotiations, state power, and international legal arrangements.     

杂交水稻乳熟期~(14)C-葡萄糖同化物的运转分配与产量的关系

利用放射性同位素~(14)C葡萄糖示踪的方法,研究杂交水稻乳熟期功能叶片同化产物的运转分配及其与谷粒产量的关系,结果表明:汕优64、V优64、D优852、植优D、秀优57、五优占2号等高产杂交组合,乳熟期功能叶片的~(14)C—同化物分配到稻穗的(％)或在稻穗的输入积比其恢复系和高产常规品种双桂36高,秀优57、五优占2号和青优159的谷粒理论产量与乳熟期~(14)C—同化物从功能叶片的输出率呈显著正相关,五优占2号的谷粒产量与乳熟期~(14)C—同化物在稻穗的输入积呈显著正相关。青优27、青优40和青A×HR18等低产杂交组台乳熟期功能叶片的~(14)C—同化物分配到稻穗的(％)或在稻穗的输入积比双桂36低,其谷粒产量也不与上述参数呈显著正相关,甚至相关系数出现负值。
