《金匮要略》“天人合一”思维哲学渊源及特点浅述

中医学整体思维是中国哲学思维在医学领域的具体应用与体现。“天人合一”整体思维是古代哲学思想的基本命题。而“天人合一”整体思维与《周易》、儒家、道家哲学思维有着深厚的渊源,因此,本文以《周易》、儒家、道家哲学思维为立足点,阐述《金匮要略》“天人合一”整体思维的哲学渊源,能丰富《金匮要略》理论的内涵,有利于把握《金匮要略》理论形成的轨迹和络脉。     

介数中心性和黄金分割理论在室内木质门参数化设计中的应用

随着建筑行业的发展,我国室内木质门销量逐年增加。由于国内建筑门洞的尺寸标准不统一,参数化设计成为室内木质门设计中的重要环节。针对木门参数化设计中存在的比例失调而导致产品美观度下降问题,根据介数中心性理论和黄金分割比例理论对室内木门参数化设计提出了新的设计思路,以实现理性和美学的统一。     

NIR spectroscopy for the optimization of postharvest apple management

Apples can be stored for long time under controlled temperature and atmosphere conditions, and therefore, non-destructive and rapid tools are required to assess fruit quality and to monitor changes during the postharvest period. The aim of this study was to evaluate the feasibility of NIR spectroscopy to optimize postharvest apple management and to follow changes in fruit quality during storage. An FT-NIR system operating in diffuse reflectance in the range 12,500–3600 cm⁻¹ was used to evaluate the physico-chemical (dry matter, soluble solids, colour and firmness) and some nutraceutical characteristics (total phenolics, total flavonoids and antioxidant activity) of ‘Golden Delicious’ apples, which were stored for about six months at 1 °C in controlled atmosphere, over two subsequent years. Spectral data were elaborated by PLS regression and LDA classification techniques. Good correlation models between spectral data and chemical and physical parameters were obtained for soluble solids, a* colour coordinate and firmness (0.81 < R² < 0.90 in calibration and 0.79 < R² < 0.89 in cross validation). Even higher correlation values (0.89 < R² < 0.95 in calibration and 0.86 < R² < 0.92 in cross validation) were obtained for indexes correlated to the antioxidant capacity of apples. The classification technique Linear Discriminant Analysis was applied to spectral data, in order to discriminate apples on the basis of storage time. Average correct classification was higher than 93% in validation and close to 100% in calibration, indicating high potential of NIR spectroscopy for the estimation of storage time of apple lots.     

定植期及摘心次数对金丝皇菊生长发育的影响

为了筛选出金丝皇菊在清水地区的适宜定植期和摘心次数，以株高15 cm、地径0.3 cm的健壮扦插苗为材料，采用5个定植期(主区)和4个摘心次数(副区)的二因素裂区试验设计，研究了不同定植期及摘心次数对金丝皇菊生长发育的影响。结果表明，不同定植期处理间株高和冠幅差异显著，不同摘心次数处理间株高差异显著，冠幅差异不显著。定植期为5月20和5月30日、摘心次数为2～3次的处理，特级花占10.4%，一级花占19.4%，产值较高。定植期为5月10和5月20日的处理，初花期均为10月20日；定植期为5月30日、摘心1次的处理，初花期为10月20日，摘心2次的处理延迟5 d，摘心3次的处理，延迟8 d；6月9日以后定植的，随着摘心次数的增多，初花期显著推迟。说明定植期为5月20日和5月30日、摘心次数2～3次为金丝皇菊最佳定植期和摘心次数。
