内容提要：实验依据VOE标准研究范式验证了语词遮蔽效应的存在，并探讨了不同目标面孔呈现时间对语词遮蔽效应出现的影响。实验结果表明：（1）目标面孔呈现时间为1秒，语词遮蔽效应显著。（2）不同目标面孔呈现时间的条件下言语描述对再认成绩的影响不同，从1秒到5秒，随着呈现时间的增加，语词遮蔽效应趋于消失，并出现一定程度的语词助长。

Two experiments based on the standard paradigm of verbal overshadowing effect (VOE) were conducted to explore the variation of VOE along with changes on target face presentation time. The results showed that VOE was significant when the target face presentation time was 1 second, but tended to disappear when the target face presentation time was pro-longed to 5 seconds. Moreover, along with the extended target face presentation time, verbal description was found to be able to promote the subjects’ identification.

目的：探讨Tween对红细胞表面抗原(主要是ABO和D抗原)的遮蔽效果以及红细胞的稳定性。方法采用不同浓度的Tween孵育不同血型红细胞,并对其孵育前后抗原效价进行比较,以及采用形态观察,渗透脆性、自身溶血率、氧饱和度( SO2)、RBC平均指数检测和上清液游离血红蛋白测定判断孵育后红细胞的基本功能变化,以证实其稳定情况。结果 Tween-20对D抗原的孵育效果较好且稳定,减弱程度保持在“+”以上,B抗原遮蔽略差且并不稳定,A抗原的遮蔽效果较弱,优势浓度在0.004%附近。 Tween-80对D、B遮蔽效果差异并不明显,在0.74%、0.80%附近遮蔽效果较好,保持在“+”以上。结论 Tween-20, Tween-80可以遮蔽RBC表面抗原,并使其减弱程度保持在“+”以上,RBC形态及功能没有发生变化。

Objective To explore the shielding effect that Tween has made on the erythrocyte’ s surface antigen( ABO and D antigen mainly) and the stability of the RBC. Methods Various types red blood cells’ surface antigens were incubated with different concentrations of Tween,then the titers of RBC’ s surface antigen before and after incubation were compared. The erythrocyte’ s function alterations and sta-bility through the morphological obersavation,the osmotic fragility,RBC’ s own hemolysis rate,oxygen saturation( SO2 ) ,routine test of blood as well as the supernatant of free hemoglobin determination were confirmed. Results The masking effect of the Tween-20 on D antigen with the weaken titer keeping above“ +” was better and more stable than that on A,B antigen. The impact on B antigen was a little worse,and A was the worst. The advantaged concentration is about 0. 004%. Besides,the influence of Tween-80’s on B and D antigen was not apparent e-nough. Among all of the concen

针对常规雷达检飞方法耗时耗力且难以全面掌握问题,提出一种利用数字高程模型(DEM)数据的雷达地形遮蔽盲区计算方法.该方法将雷达不同方位距离处的地面高程数据转换为雷达观测仰角,与雷达自由空间垂直威力图比较,确定地形遮蔽点,形成雷达方位地形遮蔽剖面,全部方位地形剖面即构成雷达地形遮蔽盲区,进而确定不同高度层的雷达探测威力范围.仿真结果表明,该方法结合雷达检飞,可形成更全面、准确的雷达探测威力图,为雷达部防作战提供可靠的雷达探测威力范围依据.

Aimed at the problem that the conventional tracking the flight by radar is demanding and hard to control overall, this paper puts forward a method for computation of radar terrain masking blind zone by taking up the digital elevation model (DEM). In this scheme, the surface elevation data from various azimuth range of the radar can be converted to its observation elevation, the terrain masking point be pinned up to form the masking section of radar azimuth terrain, in comparison with the perpendicular power pattern of radars’free space. And then all those sections form the terrain masking blind zone of the radar, thus determining the radar’s detection power range at various altitude levels. Simulation results show that this proposed method can be used for more comprehensive and accurate map of radar detection power by combining radars’tracking the flight, thus offering a reliable basis of radar detection power range for the deployment and defensive operation of radar.
