洪家渡水电站工程高边坡综述

乌江洪家渡水电站坝址河谷深切300余m,硬质岩与软质岩相间分布,岸坡地形陡峻,软弱夹层发育,卸荷、崩塌等物理地质作用强烈。根据坝址地质条件与电站枢纽布置,工程存在:隧洞群进水口同向高边坡整体稳定问题;坝肩开挖、隧洞进出口开挖、厂房开挖及料场开挖等高边坡稳定问题;泄洪冲刷及雾化区1号、2号塌滑体高边坡稳定问题;王家渡堆料场、瓦房寨砂石系统高边坡稳定问题。因此,工程高边坡稳定问题是本工程的主要工程问题之一,但通过参建各方共同努力,本工程高边坡处理都取得了圆满成功。     

The Person Reference Process in Spontaneous Trait Inferences.

Five studies examined whether spontaneous trait inferences uniquely reference the person who performed a trait-implying behavior. On each study trial in 5 studies, participants saw 2 faces and a behavioral sentence referring to one of them. Later, participants saw face-trait pairs and indicated whether they had seen the trait word in the sentence presented with the face. Participants falsely recognized implied traits more when these traits were paired with actors' faces than with control faces. This effect was replicated for a large set effaces (120), after a week delay between study and recognition test, when equal attention was paid to each face, and when the orientation of the face at recognition was different from the orientation at encoding.

不同表面预处理对有机电致发光显示器性能的影响

从生产角度研究了基板表面的预处理工艺对OLED性能的影响,分别用UVOzone、氧Plasma以及两者相结合的方式对基板进行表面处理,并按照生产工艺制作器件,从接触角、方阻以及光电特性等测试结果对各种表面处理的样品进行比较。结果表明以上处理都改善了器件性能,不同程度提高了器件的清洁度、亮度和发光效率,其中UVOzone和氧Plasma结合的方式处理效果最为显著,器件在10V时亮度达到79920cd/m2,比其他两种处理方式亮度提高约25%。     

高温酸化助排剂HC2-1的研究

为了满足高温油藏和深井酸化作业残酸返排的需要，通过表面活性剂的筛选和复配研究，得到了高温酸化助排剂HC2—1。其性能评价结果表明，HC2—1具有使用浓度低、表面活性高的特点，在20％的HCI溶液中，当其浓度为50mg／L时，表面张力为20．7mN／m；具有良好的耐温性能，在180℃下恒温48h，HC2—1仍保持较高的表面活性；具有良好的耐盐能力，加有HC2—1的20％HCl溶液和CaCO3反应至HCl完全消耗，整个反应过程体系无新相生成且表面张力基本不变；可增大酸液体系的润湿角，进一步降低毛细管阻力，使酸液返排率由46％提高到97％，在促进酸液返排的同时与原油不发生乳化反应。

Failure analysis of a broken tooth

Several days after heart surgery, a patient discovered his upper right canine tooth had broken at the root. Such tooth damage, recognized post-operatively, is usually assumed to be caused by blunt mechanical force from an instrument used by the anesthesiologist during placement of a breathing tube at the start of surgery. In this case, the patient had saved the crown portion of the broken tooth, and it was possible to examine the root fracture characteristics. The curvature and direction of the crack path and natural tooth situation suggested that failure could be described through a cantilever beam model. This was confirmed when a whole extracted sample tooth was embedded and broken by a measured force in a manner consistent with the model. The resulting fracture surface matched that of the patient’s broken canine tooth. However, the high load and force direction necessary to fracture the root was inconsistent with forces applied during the anesthesia procedure. The failure analysis and further investigation indicated tooth clenching on the breathing tube during recovery was the likely cause of fracture. This paper presents an alternate explanation for intubation-related dental injury, demonstrates the practicality of fractographic analysis of biological materials, and introduces a methodology for simulating in vitro tooth settings for mechanical testing.
