TOPEX/POSEIDON卫星是于1992年8月10日发射的对地定向三轴稳定卫星。在姿态测量和控制分系统的全套敏感器中包含有2个相同的地球敏感器组件(ESA)。每一个ESA提供滚动和俯仰两轴姿态误差测量,这些信号一般用于星上计算机(OBC)故障检测和校正逻辑,在OBC初始捕获处理及地球指向安全保持模式运行期间也可作为主要的姿态测量。TOPEX/POSEIDON卫星发射后不久,即观测到地球敏感器信号的异常。本文叙述该地球敏感器的在轨性能及已实现的软件修正,这些软件修正保证卫星对异常数据的响应不会对卫星或飞行任务产生不利影响。本文还讨论了ESA异常机理与带电粒子作用的关系。这项工作是由国家航宇局委托加州理工大学的喷气发动机实验室进行的。

目的:探讨牙本质胞外基质成分(dentinextracellularmatrixcomponents ,DMCs)对体外血管形成的影响。方法:10 %EDTA提取健康人牙中的DMCs。血管内皮细胞成纤维细胞共培养体系在含有DMCs (0 .0 0 0 1～5mg/ml)的培养液中培养11d ,PECAM 1和vonWillebrand因子显色血管后采用图像分析系统测量血管总数、长度及分支数。添加刺激因子VEGf组及抑制因子Suramin组分别作为阳性和阴性对照组,单纯培养液为空白对照组。各项指标与空白对照进行Student T统计分析。结果:低浓度DMCs(0 .0 0 0 1～0 .0 1mg/ml)可产生类似VEGf组刺激血管形成的效果,且最佳作用浓度为0 .0 1mg/ml。较高浓度DMCs (0 .1～5mg/ml)则对血管形成具有显著的抑制效应(P <0 .0 0 1)。结论:DMCs对血管形成具有计量依赖型影响效应。提示这一计量依赖型效应可能正是牙髓损伤后导致不同修复结果的原因。

疏森草地不仅对草地畜牧业的发展有着巨大的潜力,而且还是一座无污染的氮肥加工厂。研究了除草剂防除灌丛对星毛栎(Quercus stellata Wangenh.)、马丽兰得栎(Quercus marilandicaMuenchh.)群落生物量及氮的影响。试验设4种处理。1973年春每公顷喷洒丁塞隆除草剂(N-[5-(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl]-N,N′-dimethylurea)2.2kg防除灌丛。试验期21个月(1993年6月～1995年2月),试验小区面积375m^2,测定土壤、根系、枯枝落叶、草本植物、直径小于2.5cm的木本植物、直径大于2.5cm的木本植物的主杆、叶片和枝条的总氮量。1994年6月高羊茅氮的贮存量是须芒草和当地原有植被的6～7倍,1994年10月,1995年2月高羊茅和须芒草地上生物量差异不显著,但均高于当地原有植被,高羊茅氮的贮存量是须芒草的2倍。播种了高羊茅的处理枯枝落叶及其含氮量增加较多。4种处理土壤总氮含量平均为5100kg/hm^2,处理间差异不显著。植被不同层次间总氮含量变化不明显。清除灌丛和播种牧草对处理21个月后的总氮贮量影响较小,但会引起氮在草本植物层、枯枝落叶层重新分配。

Purpose: Sports participation and physical fitness are widely beneficial for young people, yet activity levels among young people are *** growing popular media attention on the participation of sexual minority(e.g., lesbian, gay, and bisexual) youth in sports and various campaigns to improve the often homophobic climate of sports, there is limited evidence that sexual minority youth participate in sports. Our aim was to provide a current portrait of sports participation among 3 groups of sexual minority youth(e.g., lesbian, gay, and bisexual) in British Columbia, Canada, as well as to document population ***: Pooled population-level data from British Columbia, Canada(n = 99,373) were used to examine trends and disparities in sports participation among sexual minority and heterosexual youth. Age-adjusted logistic regression models were used to examine changes in participation over time and disparities in participation over time(1998—2013).Results: We found an overall decline in sports participation and physical activity(PA) for all youth. Sexual minority students were less likely to participate in formal sports(with a coach) and informal sports(without a coach) compared with their heterosexual peers. The disparity in participating in informal sports between heterosexual and sexual minority youth has narrowed over time for some sexual orientation groups, whereas the disparity in participating in formal sports has widened over time in some ***: This study provides a comprehensive examination of sports participation among sexual minority youth over the past 15 *** changing societal attitudes and laudable efforts to reduce homophobia in sports, results suggest that there are continued barriers to participation for sexual minority youth. further research is needed to understand the factors that limit sports participation for these youth and to inform program development. PA is critical to lifelong health and well-being, and
