从关联分析法看如何改善沥青抗老化性能

用灰色关联分析法研究了沥青抗老化性能与沥青化学组成之间的关联程度，结果表明，影响再生沥青性质的主要因素是沥青中的芳烃和胶质的含量。通过添加芳香组分能改善沥青四组分之间的配伍性，从而可以改善再生沥青的抗老化性能。并通过对再生剂进行富芳处理，验证了上述结论。

Contributions of Metaknowledge to Retrieval of Natural Categories in Semantic Memory.

Retrieving the answer to a general knowledge question has been shown to involve two metacognitive processes--a feeling-of-knowing that initiates the search of long-term memory and a willingness to continue searching until an answer can be confidently stated. To extend this model, college students were asked to retrieve as many members of 2 natural categories as they could in 1 min. Examination of the points at which they switched categories revealed that they searched longer in categories of higher potency, and they switched earlier when the other category was of higher potency. They also searched the first category longer when they were allowed to switch only once during a trial rather than as often as they wished. It was concluded that feeling-of-knowing maintained search of a category and also contributed to the willingness to continue searching, and the constraint on switching impacted the willingness to continue.

The effects of widowhood on physical and mental health, health behaviors, and health outcomes: The Women's Health Initiative.

This study examined whether widowhood was associated with physical and mental health, health behaviors, and health outcomes using a cross-sectional (N=72,247) and prospective (N=55,724) design in women aged 50-79 years participating in the Women's Health Initiative observational study (85.4% White). At baseline, married women reported better physical and mental health and generally better health behaviors than widowed women. Whereas women who remained married over the 3-year period showed stability in mental health, recent widows experienced marked impairments and longer term widows showed stability or slight improvements. Both groups of widows reported more unintentional weight loss over the 3-year period. Changes in physical health and health behaviors were inconsistent, with generally small effect sizes. Findings underscore the resilience of older women and their capacity to reestablish connections, but point to the need for services that strengthen social support among women who have difficulty during this transition.

遗落的明珠——浅谈岑参山水写景诗的艺术价值

唐代诗人岑参以边塞诗闻名于中国古代诗坛，同时他的山水写景诗写得也毫不逊色，取得了极高的艺术成就，特别是其清淡、清新、清旷、清丽的“四清”并行的艺术风格尤为突出。由于历史和个人原因，岑参的山水写景诗历来鲜为人知，但这并不能否定其特有的艺术价值。

两缸天然气发动机工作均匀性分析

对一台火花点火式两缸天然气发动机进行了缸内示功图、进气压力波、空燃比、缸盖及活塞温度场和排放等项目的测试。试验和分析表明，两缸进气道中存在着明显的压力波动，波动程度取决于发动机工况。两缸混合气的质和量都不均匀，一缸空燃比偏浓，燃烧不完全，后燃倾向大；二缸空燃比较合适，燃烧过程较完善。两缸的尾气排放量相差不大。据此，可应用稀燃、快燃技术，以提高燃烧速度，改善燃烧过程；同时调整进气系统特性，将两缸混合气的质和量的不均匀性降到最低限度。
