Interpreting the Good Life: Growth Memories in the Lives of Mature, Happy People.

In 2 studies, the authors examined autobiographical memories for the presence of 2 growth orientations that were expected to correspond differentially to maturity and well-being, which are considered to be key facets of "the good life" by L. A. King (2001). Mature participants emphasized integrative memories (conceptual integration and learning), whereas happy participants emphasized intrinsic memories (humanistic concerns). Both kinds of growth memories correlated more strongly with eudaimonic than with hedonic measures of well-being. Growth memories were largely independent of Big Five traits in relation to maturity and well-being. Finally, older participants were more likely than younger participants to have greater maturity (marginally) and well-being, but this was in part explained by older participants' greater tendency to have growth memories. The discussion considers the role of growth memories in the intentional cultivation of the good life. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

确定厚壁圆筒初始屈服压力的一种实验方法

基于厚壁圆筒的弹性失效准则所确定的圆筒的初始屈服压力与材料的屈服极限的关系，设计了一种测定厚壁圆筒初始屈服压力的实验方法，并测得了一组实验数据。通过对该实验数据的分析得到了圆筒的初始屈服压力。该实验值与理论值误差较小，表明了该实验方法具有较好的可靠性。     

模拟点蚀油气管线钢的拉伸性能

根据发生点腐蚀的油气管线基体有许多点蚀坑的特点,通过计算机产生随机数确定点蚀坑的位置,用小钻头打孔的方法模拟X60管线钢基体的多孔特征进行拉伸试验,测得其弹性模量、屈服强度和抗拉强度,并将理论计算值与前二者进行比较和修正,给出了多孔钢材的抗拉强度与孔隙率的函数关系.结果表明,多孔钢材弹性模量的实测值随孔隙率的变化与理论预测结果较为吻合;钢材实测屈服强度也随着孔隙率的增加而减少,但在较高孔隙率时其减少趋势变缓;衰减速率的实测值略大于理论预测值;实测抗拉强度随孔隙率的变化曲线与屈服强度相似,但对孔隙率更敏感.     

Further study on different dopings into PbWO4 single crystals to increase the scintillation light yield

Since we presented our preliminary result (Nucl. Instr. and Meth. A 486 (2002) 170) at SCINT2001, we have continued our efforts to increase the light yield (LY) of PbWO₄ scintillators by extending different dopings with an aim to find a possibility of using PbWO₄ successfully in Positron Emission Tomography (PET). Overall result obtained for single doping as well as double and tripple co-dopings are summarized, including decay characteristics and radiation hardness. The LY in non-doped PbWO₄ crystals with a size of 10×10×(20–30) mm³ is 25–35 photolectrons/MeV (phe/MeV) corresponding to 3–4% of the LY in BGO, when measured with a bialkali photomultiplier during a gate of 1 μs. The maximum LY increased to 49 phe/MeV for single doping with Mo⁶⁺, 80 phe/MeV for double co-doping of Mo⁶⁺+Sb⁵⁺, and 85 phe/MeV for tripple co-doping of Mo⁶⁺+Cd²⁺+Sb⁵⁺. The radiation hardness is larger than 10⁵ Gy for each of the samples co-doped with Mo⁶⁺+Sb⁵⁺ and Mo⁶⁺+Cd²⁺+Sb⁵⁺, while it is much poorer in PWO:Mo⁶⁺. In each of these co-doped samples, a medium-speed green emission in the microsecond range is created besides the fundamental fast (a few nanoseconds range) blue one, giving a peak at 500 nm in the radioluminescence spectrum similarly as in PWO:Mo⁶⁺.     

不同插秧量对东北杂交稻与常规稻产量结构的影响

对东北杂交稻与常规稻的产量形成过程和产量结构进行了分析。结果表明：杂交稻比常规稻增产的主要原因在于杂交稻的经济系数显高于常规稻，这主要得益于杂交稻后期光合产物向籽粒的转移率较高。在产量结构上，杂交稻的穗粒数多、千粒重大，但穗粒数的优势主要来源于二次枝梗，这也造成了杂交稻的结实率偏低，成为限制杂交稻产量潜力发挥的瓶颈。进一步发挥杂交稻的杂种优势，需要从提高后期光合能力和提高结实率两方面人手。杂交稻与常规稻有各自适宜的栽培方式，插单苗有利于提高杂交稻的平均穗重、千粒重、结实率，并最终使产量提高；而插3苗更适于常规稻生产力的发挥。     

大穗型超级杂交粳稻辽优3072产量结构及灌浆特性研究

对北方大穗型超级杂交粳稻辽优3072进行了产量结构和灌浆特性的研究。结果表明：辽优3072在产量结构上表现出了较强的杂交优势，比对照辽粳294增产明显。辽优3072在灌浆上的特点为穗上、中、下各部间干物质充实及灌浆速率差异较小：穗下部灌浆启动早，后期灌浆速率大；整穗表现出较强的持续灌浆能力。辽优3072良好的籽粒灌浆特性是其在产量上表现出超高产的生理基础之一。同时探讨了利用水稻杂交优势选育具有特异灌浆特性的杂交组合的育种思路以及在北方冷凉稻区推广大穗型超级杂交粳稻品种的可能性。
