基于凸空间分析法的浙南丽水明清时期民居空间形态研究

浙江民居年代久远,蕴含着丰富的历史信息与地域文化。选取浙南丽水地区的缙云县河阳村循规映月、莲都区西溪村山川环拱、松阳县石仓村乐善堂三处民居作为研究对象。利用空间句法理论的凸空间分析法以及基于Depthamp软件的整合度、选择度、连接值与总深度值四个指标,定量分析丽水民居空间形态的成因。通过拓扑模型分析可知堂屋在浙南民居空间布局中处于核心位置,其空间形态深受儒家礼制文化和宗法制度的影响,弄和檐廊在浙南民居中作为主要的交通流线起到了空间关系组织的作用。

Water blocking effect caused by the use of hydraulic methods for permeability enhancement in coal seams and methods for its removal

To research techniques for removing the water blocking effect caused by hydraulic applications in coal seams,the use of surfactants is proposed,based on the mechanics of the water blocking effect.Centrifugal experiments were used to validate the effects of using surfactants;the results show that after dealing with vacuum saturation with water,the volume of micropores decreases,which results in a larger average pore size,and the volume of transitional pores,mesopores,macropores and total pores increases.Based on the distribution of pore size,the operation mode of ‘‘water infusion after gas extraction,then continuing gas extraction" is recommended to improve the volume of coal mine gas drainage.When the reflectance of vitrinite in coal samples is less than 1,using the surfactants Fast T,1631,APG,BS can mitigate the damage caused by the water blocking effect.But when the reflectance of vitrinite is larger than 1.4,the damage caused by the water blocking effect can be increased.When the surfactant CMC is used in hydraulic applications,the capillary forces of coal samples are almost negative,which means the capillary force is in the same direction as the gas extraction.The direction of capillary forces benefits the gas flow.So,using CMC can play an active role in removing the water blocking effect.Centrifugal experiments confirm that using CMC can effectively remove the water blocking effect,which has a beneficial effect on improving the gas drainage volume.

社区档案服务的行动逻辑:一个过程、主体和价值的三维框架

城市管理体制的变革和信息技术的发展,带来了社区治理的诸多挑战。社区档案资源的利用、管理和服务等过程分别指向社区档案资源的行政价值、社会价值和人本价值目标,并由其构成了社区服务治理的框架结构。从社区档案的三个过程到档案资源的三种价值传导,需要建构由政府主导的档案利用、馆社共建的档案管理和公众参与的档案服务等为核心内容的社区档案管理行动逻辑。

太子参罗汉果饮料生产工艺研究

以药食两用的罗汉果和太子参为原料,通过实验优化了水浴加热提取罗汉果活性成分和超声破碎提取太子参活性成分的方案,同时对饮料中添加柠檬酸的口感调配方案进行探索。结果表明,该复合饮料最佳生产工艺为:罗汉果在100℃水浴下加热50 min,太子参在200 W提取功率下,超声波处理9 s,提取20 min;该复合饮料的最优配料添加量为罗汉果干果5 g/L,太子参5 g/L,柠檬酸0.10 g/L,此配方饮料感官评价最佳。

双侧闭孔动脉、静脉变异1例

笔者在解剖一具老年女性尸体时,发现该标本双侧闭孔动静脉发出位置变异,由闭孔动静脉变异支(死亡冠)替代。尸体标本10%甲醛固定,来源于湖南师范大学医学院,年龄不详,身高约155 cm,外观无手术瘢痕及畸形。测量工具为游标卡尺(精确度0.01 mm),所测数据为血管于体内压扁后之外径。经查阅国内外文献,闭孔动脉或静脉单侧变异多见,双侧变异少见^([1-2]),双侧闭孔动脉、静脉同时变异未见报道。为积累解剖学资料,现作报道。

刑法上相同商标的认定标准及比对方法

【裁判要旨】刑法意义上的相同商标并不以与注册商标完全相同为限,在司法实践中应当严格把握视觉上与注册商标基本无差别,足以对公众产生误导的认定标准。上述两个构成要件须同时满足,缺一不可,尤其应重视视觉效果基本无差别的构成要件,以免造成刑罚的不当扩张。
