摘要：The main reason why the application of nuclear technology in petroleum exploration has not yet been accepted by most exploration workers is that they are not clear about the homologous distribution features of oil and gas fields and radioactive radiation. The authors hold that the disequilibrium of uranium, radium and radon as a natural radioactive series is the basic feature in the use of this technology in petroleum exploration. The invention Gamma-ray Spectral Measurement of the Equilibium Coefficient Kp and Its Embodiment of the senior author now can readily solve that problem and replace the impedient measure of normalization of uranium and potassium to thorium that had to be proposed before. Application of this impedient measure has some limitations. In areas where the surface is covered by beach or river sands, thorium minerals such as monazite may be concentrated by placering. This could result in local thorium highs that would yield local uranium and potassium lows after normalization to thorium, and these would constitute false anomalies.

摘要：The design and synthesis of bio-nano hybrid materials can not only provide new materials with novel properties, but also advance our fundamental understanding of interactions between biomolecules and their abiotic counterparts. Here, we report a new approach to achieving such a goal by growing CdS quantum dots （QDs） within single crystals of lysozyme protein. This bio-nano hybrid emitted much stronger red fluorescence than its counterpart without the crystal, and such fluorescence properties could be either enhanced or suppressed by the addition of Ag（I） or Hg（II）, respectively. The three-dimensional incorporation of CdS QDs within the lysozyme crystals was revealed by scanning transmission electron microscopy with electron tomography. More importantl~ since our approach did not disrupt the crystalline nature of the lysozyme crystals, the metal and protein interactions were able to be studied by X-ray crystallography, thus providing insight into the role of Cd（II） in the CdS QDs formation.

摘要：介绍用于对航空发动机部分进行X射线检测的微焦点棒阳极射线管,这种棒阳极射线管要求其可以在高强度的X射线下进行长时间的曝光拍摄,应具有很好的稳定性和持久性,故需要采用新的结构设计和冷却系统。探讨了减少射线管使用中所产生热量和改进冷却系统等问题,提出将密封胶圈纳入冷却循环的方法。解决了这些重大技术问题后,组装出紧凑耐用的棒阳极射线管,应用到了飞机发动机检测中,降低了设备的故障率,优化了发动机制造厂的X射线检测过程。

摘要：创造出一个接近自然居住状态的空间,在人类还与大自然连结甚深的时期,除了穴居之外,有一种原始又迷人的住居方式:从最初将住所设置在树上到为了更亲近大自然而建造的树屋。树屋,顾名思义随着树而建造,因此树的形态与高度便决定了住所的状态,在森林中每棵树的高度不同,以至于每个树屋的高度也会有差异,这即是此案最初的设计原型。设计师希望能创造出一个接近树屋自然居住状态的空间。

摘要：通过与实验室的CMP和集成工程师合作,采用测试系统观察两种或两种以上混合配方磨料的选择比。实验数据表明,通过改变单个化学试剂组分的浓度改变磨料的选择比效果突出,磨料配方师可以简便地修改磨料配方。这种方法的优点是,如果改变集成方法或特殊膜层,可以很快地重新优化磨料。如SiN膜取代TEOW淀积氧化物膜,对新系统可以容易地重新优化磨料。介绍了几种磨料组分浓度的去除速率和选择比。

摘要：美国玻璃师史蒂夫·卡莱(Steve Klein)是近代琉璃创作其中一名大师,擅长透过使用形状、颜色、线条及质地的平衡关系去创作千变万化的立体艺术品。像"Balance 47 Three′s Company"在底部起伏的四方环境中,"瓶子"与"三球"彼此相背对,一股拉扯与凝聚的力量油然而生。他不只一次强调,如何在个人想法、热工材料,地心引力之间取得平衡是他最大的挑战。自二十世纪末开始,台湾重新找到琉璃这种创作媒体。

摘要：初听到松桂奇这名字,还以为是来自日本的品牌,后来谜团解开,原来是台湾原创品牌。设计师刘奇升各取了自己和父母名字中的一个单字,成为自己新品牌名称,商品带着浓浓的民俗风味,加上超可爱造型,成为贵妇名媛的最爱。刘奇升之前在日本、法国念服装设计学校,因表现良好,曾代表法国角逐1995年的国际设计师新人奖并获得首奖。

摘要：High-entropy alloys(HEAs)have been widely studied due to their unconventional compositions and unique physicochemical properties for various ***,for the first time,we propose a surface strain strategy to tune the electrocatalytic activity of HEAs for methanol oxidation reaction(MOR).High-resolution aberration-corrected scanning transmission electron microscopy(STEM)and elemental mapping demonstrate both uniform atomic dispersion and the formation of a face-centered cubic(FCC)crystalline structure in Pt Fe Co Ni Cu *** HEAs obtained by heat treatment at 700℃(HEA-700)exhibit 0.94%compressive strain compared with that obtained at 400℃(HEA-400).As expected,the specific activity and mass activity of HEA-700 is higher than that of HEA-400 and most of the state-of-the-art *** enhanced MOR activity can be attributed to a shorter Pt–Pt bond distance in HEA-700 resulting from compressive *** nonprecious metal atoms in the core could generate compressive strain and down shift d-band centers via electron transfer to surface Pt *** work presents a new perspective for the design of high-performance HEAs electrocatalysts.
