Comparison of Drought-Resistance about Three Wild Rocky-Grasses

In this experiment, using the methods of drought-stress in the pot and PEG simulative drought-stress, three native rocky-slope grasses Pogonatherum panideum（Lam.） Hack, Erioophorum comosum nees and Cynodon dactylon cultivated in the pots were selected as materials to study their drought-resistance by analyzing the indexes such as the leaf area index, the drying roots accumulation, the holding water ability of leaf, the relative conductance of leaf, the soluble protein, chlorophyll. At the same time, by comparing with membership function value of each index, the order of each grass drought-resistance was decided. The results showed that the drought-resistance of Erioophorum comosum nees was stronger than Cynodon dactylon and drought-resistance of Cynodon dactylon was stronger than Pogonatherum panideum （Lam.） Hack. The purpose of the experimental results was to find theoretical foundations for selecting and cultivating native protecting-slope vegetations to adapt to rocky slopes.     

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.
