马克思从人的生产能力角度阐释的历史三阶段理论,是唯物史观的重要组成部分。其中,关于“自由个性”的理想社会涉及两个基础条件:一是“个人全面发展”,二是“人们共同的、社会的生产能力成为从属于他们的社会财富”。社会主义市场经济中的市场作用针对前者,政府作用则彰显后者,双方从实践层面补充了实现未来理想社会的逻辑环节,确证了“自由个性”的社会必然到来。

近年来中国城市O_(3)污染问题日益突出,近地面O_(3)已成为沈阳市的主要空气污染物之一。基于沈阳市2019年近地面臭氧(O_(3))及其前体物(VOCs和NO_(2))的逐时数据,结合同期气象观测资料,研究了2019年沈阳大气O_(3)的季节变化特征,分析了V... 详细信息

近年来中国城市O_(3)污染问题日益突出,近地面O_(3)已成为沈阳市的主要空气污染物之一。基于沈阳市2019年近地面臭氧(O_(3))及其前体物(VOCs和NO_(2))的逐时数据,结合同期气象观测资料,研究了2019年沈阳大气O_(3)的季节变化特征,分析了VOCs和NO_(2)以及气象条件对O_(3)生成的影响;利用最大增量反应活性法(MIR)估算了沈阳大气VOCs的臭氧生成潜势(OFP),并运用正交矩阵因子分解法(PMF)进行了沈阳夏季VOCs的来源解析。结果表明:2019年沈阳市O_(3)平均质量浓度夏季最高,其次是春季和秋季,冬季最低;四季O_(3)日变化特征均表现为单峰型,质量浓度峰值出现在14:00左右,谷值出现在07:00左右。沈阳市O_(3)质量浓度与温度、风速均呈现正相关关系(P=0.001,P=0.005),与相对湿度呈负相关关系(P=0.005);当温度达到30.0℃以上,O_(3)质量浓度明显升高;风速低于3.0 m·s^(-1)时O_(3)质量浓度小于75.0μg·m^(-3),而风速超过4.0 m·s^(-1)时O_(3)质量浓度迅速升高至100μg·m^(-3);湿度小于20%时O_(3)质量浓度较高,当湿度大于80%时O_(3)质量浓度显著降低,由75.0μg·m^(-3)降低至58.7μg·m^(-3)。O_(3)平均质量浓度与前体物VOCs和NO_(2)质量浓度呈负相关关系(P=0.005),O_(3)平均质量浓度最大值对应的NO_(2)质量浓度区间为20.0-30.0μg·m^(-3)。2019年沈阳市大气VOCs的臭氧生成潜势依次表现为烯烃>芳香烃>烷烃>炔烃,烯烃在4个季节均为最大贡献者,表明烯烃对沈阳市O_(3)生成具有重要贡献。夏季沈阳市VOCs主要来源于石油化工源、溶剂使用源、液化石油气污染源、燃烧源和机动车排放源。沈阳作为我国传统重工业基地,加强对石油化工、溶剂使用和燃料挥发等方面的监管是降低沈阳市大气O_(3)质量浓度水平的有效途径。该研究可以为沈阳市O_(3)污染治理提供重要参考。

The conventional wisdom has been challenged recently that microblades with handles are only tools for hunting and gathering in the Neolithic Age. Some scholars argued that microblades actually played an important part in the early agricultural development in the Neolithic. However, both of these opinions lacked direct evidence. Environmental scanning electron microscopy (ESEM) is used to analyze the residues of the bone-handled microblade excavated at the Shangzhai site in Pinggu, Beijing. The ESEM observation and EDX analysis show that at the edge of this bone-handled microblade are Ca, P, C, O or C, N, O, etc, which provide direct evidence for determining its function, namely that this microblade may have been dealt with animals. In addition, there was a layer of glue at the back of the microblade with barium and zinc salt distributed evenly in it, this new discovery sheds new light on adhesive technology in ancient China.

Prehistoric groundstone tools including slabs (metate, mo-pan) and mullers (mano, mo-bang) are often considered to be tools that were used to process cereals in ancient China. Most archaeologists believe that groundstone tools are indicators of an agrarian economy. This study employed starch grain analysis to examine a slab and a muller excavated from the Shangzhai Site (7500-7000 cal a BP), Beijing. Identifiable starch grains recovered from the stone tools were classified into 9 genera and 12 species, most of which were from acorns and foxtail millets. Remains from the oak species Q. mongolicus, Q. acuttssima, and Q. dentate were identified as well as a few starch grains from broomcorn (Panicum miliaseum) and bean (Vigna sp.). Other starch grains were from unidentifiable roots and grasses. A variety of starch grains indicates that the grinding stone tools were used to process not only cereals, but also other seeds or roots that had to be ground or husked, thus bringing into question the aforementioned cereal hypothesis. Because the numbers of starch grains from nuts and millets were so large, both gathering and cultivation might have been important economic patterns before 7000 years ago in Beijing area. Moreover, the starch remains are derived from plants that indicate that the paleoclimate of Beijing was wetter and warmer than today’s.

资本现象存在于人类文明史中一个特定时代,是人类在“独立性”时期的基本发展方式,承担从“依赖性”向“自由个性”转变的历史使命;资本作为理性外化形态具有两个表达层次,即利益最大化目标和效率最大化手段,后者呈现从个体本位价值观向社会本位价值观转移趋势;社会主义者把握资本规律经历三个认知环节:资本是标志性劳动成果——资本是引领性生产要素——资本是过渡性历史现象,社会主义市场经济完善与该认识渐次深化同步。

人类既源自于又受制于自然界,从发展与自然界关系中争取生命自由是人类的共同目标。西方个体本位主导的资本主义市场经济,使"自由竞争优胜劣汰"机制趋近丛林法则,衍生出社会达尔文主义倾向,经由分权的政治制度体系,赤裸裸宣示为"资本至上"原则;在国际关系领域,表现为常态化国际霸凌,在国内关系领域,表现为系统性种族歧视。美国在新冠肺炎疫情中丢盔卸甲,表明"资本至上"原则已至穷途末路,需要代之以"人类命运共同体"理念。

马克思分工理论是马克思主义思想体系的基础部分。社会主义从计划经济转变为市场经济,在实践上深化了马克思分工理论:一是使分工助推生产力发展机制从自发性转变为自觉性,即从侧重生产资料转变为侧重劳动者,开创了经济发展新路径;二是使脑体分工社会形态从对抗性转变为合作性,即从阶级斗争转变为以经济建设为中心,确立了阶级消灭新模式;三是使消除分工限制的条件从客体性转变为主体性,即从自由转换分工岗位转变为劳动者脑力化,预设了共产主义新前提。
