研究了从中世纪到现在教堂钟中的合金元素包括有害元素对锡青铜冶金性能的影响，对澳大利亚和欧洲钟的样品进行了金相和化学分析，确定和论证了不同时期影响教堂钟质量的相关因素，并揭示了这些因素对过去几个世纪里教堂钟的质量起的重要作用。分析得出，钟材料的基体组织主要是由“相和（α＋β）共析相组成，其比例取决于含锡量和铸型材料。从15世纪到20世纪，钟的显微硬度有逐渐增加的趋势，仅相的显微硬度从最低160VHM20g到最高230VHM20g，（α＋β）共析相则从最低280VHM20g到最高470VHM20g。研究还发现合金元素对钟的声学性能也有影响，减少钟体的含锄量，增加铅和银的含量，可减缓钟声的衰减过程。

作者： Olivera Sveljo katarina Koprivsek Milos Lucic Diagnostic Imaging Centre Oncology Institute of VojvodinaSremska KamenicaSerbia

Because functional magnetic resonance imaging can be used for dynamic observation of functional cortical changes after brain injuries, we followed up functional magnetic resonance imaging manifestations of a language-related brain network in a low-grade glioma patient. Disease progression and therapy during a 3-year period were followed up at different time points： before and after reoperation, after radiation therapy, and 1 year after irradiation. During the whole 3-year follow-up period, the patient exhibited no neurological deficits while functional magnetic resonance imaging revealed different topologies of the language-related brain network. During disease progression and after irradiation, the language-related brain network was extended or completely transferred to the nondominant （right） hemisphere. In addition, after reoperation and 1 year after irradiation, language areas were primarily found in the language dominant （left） hemisphere. Our results suggest a high level of adaptability of the language-related cortical network of the bilateral hemispheres in this low-grade glioma patient.

食品质量在很大程度上取决于食品的包装过程。为了抑制食品变质并延长货架期,食品包装技术在食品工业的应用得到了越来越广泛的发展。利用散射介质中的气体吸收光谱技术对食品包装中的气体含量进行光学无损检测。用中心波长为760 nm的二极管激光器测量食品包装中氧气的吸收光谱信号,通过研究包装内的气体交换过程估算出包装内的氧气体积分数。实验结果表明该技术可以用来测量食品包装中的氧气含量,确保食品包装的紧密型和安全性。

Acta Mathematica Sinica,English Series 2015年第8期31卷 1339-1347页

The main goal of this paper is to establish necessary and sufficient conditions for a matrix A ∈（（lp）T,l∞）, where T is an arbitrary triangle, 1 ≤ p ≤∞, to be a compact operator. In the past,only sufficient conditions were established in almost all of those cases, by using the Hausdorff measure of noncompactness. We improve those results by applying another method for the characterizations of compact linear operators between BK spaces.

甚至在女性知道自己怀孕之前,胎盘就已开始增大,准备充当胎儿的肾脏和肝脏,直到胎儿发育出自己的肾脏和肝脏。孕12周左右,胎盘会开始替胎儿“呼吸”。胎盘表面非常复杂,甚至可以大到能盖住一匹马,胎盘一侧的胎儿血液会吸收另一侧母亲血液中的氧气。母亲血液中的氧气会无缝地流入胎儿跳动的心脏、大脑和四肢,胎儿排出的二氧化碳则会回到母亲的血液中,通过母亲的呼吸呼出。

China Foundry 2008年第3期5卷 199-204页

作者： Jaromir Audy katarina Audy Edith Cowan University South West Campus BunburyRobertson Drive6230Western Australia

The present study was set up to examine the effect of alloying elements （including harmful elements） on metallurgical features （material properties and qualitative parameters） of tin bronzes, with particular reference to church bells from Middle Ages to Current times. A driving force of this study was to identify and demonstrate features related to the quality of church bells made in different centuries. The findings have been derived via metallographic and chemical analysis of specimens of bells from various parts of Australasia and Europe. The bell materials consisted of a mixture of the a phase and the （α＋β） eutectoid essentially, in proportions determined by tin content and mould materials during casting. The samples from the 15th century to the one from the 20th century showed a progressive increase in hardness, ranging from the minimum of -280 VHM20g to a maximum of -470 VHM20g for the （α＋β） eutectoid, and -160 VHM20g to -230 VHM20g for the a phase. The investigation also shows that the sound decay of the bell decreased with lowering the wt.% of tin and increasing the wt.% of lead and silver. This information is expected to provide an additional interesting knowledge into manufacturing practices and their significance in the quality of church bells over past centuries.

研究了笼养猞猁多雄交配的结果以及雄性的成功繁殖。雄兽与发情雌兽随机配对,其繁殖成功(所产生的后代数量)不取决于与雌兽的交配顺序、交配次数与持续时间、遗传关系或雄兽的行为特征,但似乎取决于精子质量,特别是取决于形态正常精子的百分率。繁殖成功的雄兽比其竞争对手具有更多的形态正常的精子,似乎更能成功地诱发交配雌兽的排卵。证实了4窝(占总窝数的20%)幼兽的双重父亲身份。在所有情形下, 2雄1雌的交配间隔为24h 。
