国土资源遥感 , 2011, DOI: 10.6046/gtzyyg.2011.03.11
Abstract: 以内蒙古锡林河流域典型草地为研究样区,基于新一代微卫星CHRIS/PROBA高光谱遥感数据,利用双层冠层反射率模型(Atwo-layerCanopyReflectanceModel,ACRM)定量反演叶面积指数(LAI)。首先对高光谱数据进行预处理和统计分析,并结合反演结果对角度信息的敏感性进行分析,确定适于该区的最优波段组合和参数,实现了区域尺度的草地叶面积指数定量反演;然后利用该区多年实测数据的统计结果对ACRM模型进行检验,并将反演结果与MODIS的LAI数据进行相互校验分析。结果表明,CHRIS/PROBA数据用于反演稀疏草地的LAI是可行的,且利用多角度信息可以改善稀疏植被覆盖情况下LAI低估问题。本研究可为草地生态系统研究提供更精确的参数,具有一定的实际意义。

Abstract: 地表温度是气候、水文和生态等研究领域的基本参数,在地表水量和能量平衡的研究和应用中发挥着十分重要的作用。强烈的异质性是地表温度反演精度不高的主要原因之一。该文以黄河源区玛曲为研究区,评估FY-2C数据的地表温度反演精度,为将来温度反演算法和产品的进一步发展提供依据。首先,以与FY-2C相同空间分辨率的MODIS地表温度产品(MOD11B1)为地表温度真值,对反演的地表温度进行了验证;然后,利用研究区内20个采样点的土壤温度(5cm)实测数据对反演结果进行验证。结果表明,FY-2C地表温度与MODIS温度产品具有较好的相关性,相关系数在0.72~0.95之间,均方根误差在0.44~3.87K之间,平均均方根误差为1.90K;反演结果和实测数据的相关系数为0.69。

Abstract: 为了解萼片对番茄果实发育及品质形成的影响,做2组试验。试验1:分别在初花后10、15、20、25、30、35和40 d去除萼片,以不去萼片的正常果实为对照,在果实转色6 d后(成熟期)采摘,进行分析测定。试验2:分别在花后25、30和35 d及转色和成熟期采摘果实,去除萼片,以相同时期不去萼片的正常果实为对照,采后放置25 ℃ 贮藏室内观察测定。试验1的结果表明处理果实成熟时间延迟;重量、抗氧化物质Vc和类黄酮含量下降;细胞壁构成物质的水溶性果胶、共价结合果胶及总果胶含量都有所下降。在抗氧化酶活性方面,处理果实中的CAT活性低于对照,而POD活性高于对照;糖酸比低于对照,但可溶性固形物含量与对照组差异不显著。试验2的结果表明在花后30 d之前,去除萼片处理果实的乙烯产量与对照相比减少了一半。而在花后35 d以后,处理与对照间的乙烯产量无显著差异。综上,萼片对番茄果实的发育、成熟及品质形成起着促进作用。
To investigate the effects of calyx on tomato fruit development and quality formation, we did two tests.In test 1, calyxes were removed from fruits at 10, 15, 20, 25, 30, 35 and 40 d after flowering.Normal fruits with calyxes were used as control.Fruits were harvested at mature stage (6 days after turning) and analyzed.In test 2, we picked fruits at 25, 30, 35, 40 and 45 d after flowering, removed the calyxes and then stored at 25 ℃.The fruits with calyxes were used as a control.The results of test 1 showed that removal of calyxes delayed fruits ripening, fruits weight and the content of ascorbic acid (Vc), flavonoids, and fruit cell wall materials.In terms of antioxidant enzymes, catalase (CAT) activity in treated fruits was lower than that of control, while peroxidase (POD) activity was higher the sugar-acid rate decreased.There is no significant difference in soluble solids between control and treated fruits.The results of test 2 showed that the ethylene production was reduced by half when calyxes were removed from fruits earlier than 30 d after flowering.There was no significant difference in ethylene production between control and treated fruits from 35 d after flowering.It can be therefore concluded that removing of calyx had some effects on the development growth and quality of tomato fruits.

从“思辨的人”到“现实的人”—马克思对德国旧哲学的双重超越
From “the Speculative People” to “the Reality Person”—Marx’s Dual Transcendence of Old German Philosophy
 [PDF]

姜珊, 雪梅
Advances in Philosophy (ACPP) , 2014, DOI: 10.12677/ACPP.2014.34009
Abstract:
马克思对德国旧哲学的双重超越表现为马克思思维方式的转变,即把对“人”的理性思辨转化为对“人”的现实理解。马克思从“改变世界”的哲学使命出发,以“现实的人及其历史发展”为理论基点,完成了从实证唯心主义到真正的实证科学的革命,也就是实现了从旧唯物主义世界观到历史唯物主义新世界观的革命。马克思对德国旧哲学唯心论和旧唯物论的扬弃,实现了对唯物主义和唯心主义的双重超越。
Marx’s dual transcendence of old German philosophy represents as the conversion of Marx’s thinking mode, from the rational speculation of “people” to the real understanding of “person”. Starting from the philosophy mission of “changing the world”, based on the theory of “reality person and its historical development”, Marx completed the revolution from idealistic positivism to real empirical science, which realized revolution from the old materialism world outlook to the new historical materialism world outlook. Marx discarded old German philosophy of idealism and old materialism, so as to realize the dual transcendence of materialism and idealism.

Abstract: 目的:观察心理健康教育对精神病人的康复疗效。方法:采用随机对照法将100例精神病人分为研究组和对照组各50例,按规定的程序对患者进行心理健康教育,疗效评估应用临床疗效总评量表(CGI)、护士观察量表(NOSIE)、社会功能缺陷筛查量表(SDSS)和自制的健康教育评价量表(JKJY)进行入院和出院时评定,随访两年观察复发率,统计采用t检验和卡方检验。结果:研究组和对照组入院时量表评定结果差异无显著性;而出院时量表评定结果存在非常显著性差异p < 0.01;研究组病人的社会功能保持良好,两年复发率也明显低于对照组p < 0.01。结论:对精神病人实施心理健康教育具有一定的康复效果,应积极大力推广。
Objective: To observe the efficacy of rehabilitation on mental health education in patients with mental disorders. Methods: 100 patients with mental disorders were randomly divided into study group (n = 50) and control group (n = 50). The patients were subjected to mental health education according to the provisions. The efficacy was assessed by using Clinical Global Impression Scale (CGI), Nurses Observation Scale (NOSIE), Social Disability Screening Scale (SDSS) and self-made Health Education Scale (JKJY) on admission and discharge. The recurrence rate of patients was observed during the two years of the follow-up period. Statistical analysis was performed using t test and chi-square test. Results: There was no significant difference between study group and control group about scale rating on admission, but significant difference on discharge (p < 0.01). Compared to control group, social function of patients remained well in study group, and a lower recurrence rate was observed during the two years of the follow-up period (p < 0.01). Conclusion: It had the potential rehabilitation to implement mental health education in patients with mental disorders. Therefore, we should vigorously promote it.
