采用宏/微观测试手段分析了旅大油田稠油采出液乳化致稠的主要影响因素,比选评价可有效抑制油水乳化的抗乳化减阻剂复配体系;依据稠油现场集输设计方案,采用动态流变学测试方法,模拟稠油-水乳状液加剂前后表观黏度的变化规律,并利用OLGA软件计算油水液加剂前后管输流动摩阻,评价复配体系的抗乳化效率及减阻效果。结果表明:温度和含水率是影响稠油乳化的主要因素;在稠油采出液中加入200 mg/L的复配抗乳化体系(m(AP9901)∶m(TA1031)=2∶1),可有效抑制油水乳化,降低油水界面张力,还可促进W/O型乳状液破乳析水,显著降低油水混输流动摩阻,减阻率可达66.87%。

Purpose: Both alcohol dependence(AD) and sleep disturbance(SD) may render alteration of the gut microbiota, which may further disrupt the circadian rhythmicity of gut microbiota and the ***, whether or how sleep disturbance further affects the composition and rhythmicity of the gut flora in AD patients has rarely been ***, we elucidated changes of the gut flora and diurnal oscillation of gut microbiota in AD patients with poor *** and Methods: Thirty-two AD patients and 20 healthy subjects were included in this *** samples at 7:00 AM, 11:00 AM, 3:00 PM, and 7:00 PM were collected from each subject;16S rDNA sequencing was ***, AD patients were sub-grouped into the AD patients with poor sleep(ADwPS) group and the AD patients with good sleep(ADwGS) group for further ***: The ADwPS group showed higher levels of anxiety, depression and withdrawal severity than the ADwGS group(all p < 0.05).The gut microbiota in the ADwPS group differed from that of the ADwGS group(p < 0.05);At different taxonomic levels, bacterial abundance differed between the ADwPS and ADwGS groups, e.g., Cyanobacteria and Pseudomonadales(all p < 0.05).Based on the unweighted UniFrac, the β-diversity of the gut microbiota in the ADwPS group exhibited robust diurnal oscillation(p < 0.05), which were statistically insignificant in the ADwGS group, and pathogenic bacteria such as Pseudomonadales and Pseudomonadaceae exhibited pronounced diurnal fluctuation(all p < 0.05).Conclusion: AD patients with sleep disturbance exert altered profiles of the gut microbiota in composition, function and diurnal oscillation, which may provide novel perspectives into the mechanism of sleep disturbance in AD.

第十五届全国心理学学术会议

作者： Chen Feng LI jie zhong Ting Ting Wang Psychology Department of Peking University

The present study compared the empathy ability between high borderline personality disorder (BPD) symptom group and Low BPD symptom group by using questionnaires investigation and experimental approach. In the first study, the questionnaires were administered to a sample of 623 Shenzhen university’s students to examine the relationship between borderline personality disorder and empathy. Instruments include the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD, Zanarini et al,2003;Wang, Leung and zhong, 2008), Basic Empathy Scale (BES, Darrick et al,2006;Li, zhong and Lu, 2011), Interpersonal Reactivity Index (IRI, Davis,1980;Zhang, Dong and Wang, 2010), Toronto Alexithymia Scale (TAS, Taylor et al,1994;Yuan et al, 2003). 63 students score more than 6 on MSI-BPD, 162 students score 0 on MSI-BPD. The results showed that BPD group had significant higher emotional empathy ability (t=-2.95, p=0.003), higher personal distress scores (t=-6.84, p=0.000). BPD group also had significantly lower cognitive empathy scores(t=4.15,p=0.000), lower ability of empathy concern (t=3.26, p=0.001), and lower ability of perspective taking (t=2.39, p=0.018).The result of TAS-20 shows BPD have more difficulties in recognizing their feelings (t=-13.725, p=0.000), describing their feelings (t=-9.184, p=0.300), and BPD’s total scores of TAS significant higher than control group (t=-10.94, p=0.000). In the second study, we used video clip to induce emotional empathy. Subjects from the Beijing University students, among whom high group score more than 7 in MSI-BPD and low group score 0. In the negative emotion induced group, high BPD has 20 students, the low group 20s;the non-emotion induced group has high BPD of 9, the low of 20. Experimental results showed that the BPD group has more negative evaluations on negative emotion face except for evaluating disgust as agreeable. For the difference between pre-test and the next test, the dissociation between induced emotion and

滇池流域是云南省内人类活动最为剧烈的区域,在经济发展的过程中,不可避免地面临着巨大的水环境压力。研究滇池流域河湖水环境时空分异特征及其变化机理对于进一步平衡发展与保护的关系具有重要意义。先后分析了滇池流域主要入湖河道水质时空分异特点和滇池湖体生态健康空间差异性,并采用地理探测器对其驱动因素进行分析。结果表明滇池流域水环境存在显著的时空分异特征:(1)2010~2020年,滇池流域主要入湖河道水质显著提升,2010~2015年对劣Ⅴ类河道的消除较为明显,2015~2020年存在更多河道水质向Ⅱ类、Ⅲ类转变。(2)2020年,滇池全湖处于亚健康状态,但水环境质量存在空间异质性,总体上草海水质优于外海。(3)滇池流域水环境质量变化受多种因素的综合作用,其中政策优化、减污扩容是改善滇池流域水环境的最佳方案,人口与建设用地增长的交互作用对滇池流域水环境造成较大压力。
