Effects of self evaluation on late ERP components

High-density event-related potentials (ERPs) were measured when participants were required to evaluate oneself, significant others (father and mother) and the most familiar public figures (Lei Feng and Jiang Qing) based on trait adjectives. There were three referential conditions and a non-referential control condition including self-evaluation (SE), significant other-evaluation (SOE), general other-evaluation (GOE), and semantic positivity-evaluation (SPE). The behavioral data showed that RTs to GOE condition were longer than the other three conditions. Scalp ERP analysis revealed that (1) SPE condition elicited a more negative N2 than SE condition, which was associated with inhibition of responses; (2) SE condition elicited a more positive P300 than SPE condition, which was an index of attention to self-relevant stimuli; (3) there was no difference on the amplitude and latency of P300 between SE and SOE conditions, which reflected that the concept of “self” included intimate others (e.g., father and mother) in Chinese culture.     

PVC基活性炭的制备及其吸附性能的研究Ⅰ——PVC沥青的制备及其预氧化

以PVC树脂为原料,采用两个恒温段的程序升温方法加热脱氯制备PVC沥青,并通过空气预氧化法,对所制备的PVC沥青进行了预氧化处理.实验结果表明,PVC树脂在流速为100 mL/min氮气气氛中,以10℃/min速率程序升温至270℃,恒温脱氯150 min后再程序升温至410℃并恒温芳化120 min,可以制备出脱氯率和得率均较高的PVC沥青.该PVC沥青在300℃温度下,采用空气预氧化法预氧化120min,可获得增重率约为11%,氧化交联度较高、耐热性能较好的预氧化PVC沥青.FT-IR光谱分析结果表明,PVC沥青在预氧化的过程中,主要发生了氧化脱氢、脱水、CO2缩聚交联反应,使沥青形成耐热型的氧桥结构,从而达到预氧化目的.

STUDY ON POLYPYRROLE-VISCOSE CONDUCTING FIBER

The conductivity of Polypyrrole-viscose conducting fiber prepared with author's method can be shown up to as high as 2.106x10~(-2) S/cm. The main factors influencing the conductivity are the concentration of FeCl_3 used as dopant and initiator, the treatment time of viscose fiber as base material in FeCl_3 solution, temperature and polymerization time. It is found that the orientation and crystallization degree of viscose fiber keep constant before and after conducting treatment and the mechanical properties of conducting fiber is the same as that of base material. In addition, the distribution of polypyrrole in viscose fiber, and its effect on the conductivity were investigated in details by TEM.     

连续生产精品肝素钠的新工艺

本文首次报道连续生产精品肝素钠的新工艺。猪小肠粘膜的提取液在用离子交换树脂吸附之前,先经过氧化除杂蛋白和脱色过程,既提高了树脂对肝素钠的吸附率,同时也减轻提取液中杂质对树脂的竞争和毒害。肝素钠从树脂上被洗脱后,再连续地进行再氧化、除酸、碱性蛋白和核酸、酒精反复沉淀等工艺过程,生产出精品肝素钠,效价为156±5u/mg,得率为1.092±0.035亿单位/1000kg粘膜,本工艺具有较大的应用价值。
