曹县芦笋开采期预报
Prediction Model Establishment on Asparagus First Plucking Date in Cao County
 [PDF]

任崇勇,
Hans Journal of Agricultural Sciences (HJAS) , 2016, DOI: 10.12677/HJAS.2016.66024
Abstract:
利用2006~2014年曹县芦笋开采期资料和同期气温、降水、日照和相对湿度等气象资料,在分析芦笋开采期与各气象要素相关性的基础上,采用逐步回归法建立了开采期预报模型。结果表明:芦笋开采期与气温和相对湿度呈负相关,其中与1月份气温呈极显著负相关(R = ?0.855),说明气温升高,开采期提前,反之,开采期推迟,同时适宜的湿度利于芦笋的萌发及品质的形成。建立的开采期预报方程经2015年验证,效果较好,预报误差1.5 d左右,可应用于实际生产中。
Based on the asparagus first plucking date in Cao County from 2006 to 2014, combined with temperature, precipitation, sunshine and humidity meteorological elements, the correlation between the asparagus first plucking date and meteorological elements was analyzed, and the prediction model of asparagus first plucking date was established by using stepwise regression analysis. The results showed that the asparagus first plucking date was negatively correlated with temperature and humidity, and there was extremely significant negative correlation with temperature in January. This just shows that temperature increased; the first plucking date advanced; conversely, first plucking date delayed (the correlation coefficient was ?0.855). Meanwhile, suitable humidity was an advantage to germination and high quality formation. The prediction equation was verified by 2015, and the result was well. The absolute errors were about 1.5 d, which could be applied in actual production.

法典、幕友与书商----论清代江南法律书籍的出版与流通

浙江大学学报(人文社会科学版) , 2015, DOI: 10.3785/j.issn.1008-942X.2013.10.081
Abstract: ?清代江南地区出版业繁盛,其最具特色的是大量法律书籍的出版与流通。苏州、杭州等地是法律书籍出版业的中心,出版坊刻本律例全书的版本就在百种以上。商业出版的法律书籍内容更新及时,不但包括清廷颁布的律例,还囊括了诸家注释、则例和成案。江南的地方官员、幕友与书商广泛地参与法律书籍的编辑和出版。商业出版的法律典籍在清代逐步取代了官刻本,成为官员和幕友在法律审判中的主要参考书,因而对清代法律实践产生了一定影响,并且促进了法律信息的流通。

紫芝菌丝体多糖的结构鉴定及免疫活性研究

- , 2017, DOI: 10.13982/j.mfst.1673-9078.2017.4.009
Abstract: 本采用热水浸提紫芝菌丝体得到粗多糖后经DEAE-sepharose Fast Flow和Sephacryl S-200 HR分离纯化出一种新型的灵芝多糖LZ1。通过采用凝胶渗透色谱法、电镜、紫外、红外光谱、气相色谱、核磁共振、高碘酸氧化和Smith降解方法等方法对LZ1进行结构鉴定和解析,结果表明LZ1是不含核酸、蛋白质的均一多糖,其分子量为7498 u;其是由鼠李糖、岩藻糖、甘露糖、葡萄糖、半乳糖和阿拉伯糖以0.94:0.50:1.68:26.91:4.80:17.12的摩尔比组成的酸性杂多糖,其糖苷键为1→4、1→2或1→6、1→3;刚果红实验表明LZ1没有三螺旋结构;通过小鼠巨噬细胞RAW264.7体外免疫模型,研究LZ1对TNF-α、IL-6、NO三种细胞因子的分泌情况的影响发现LZ1对这三种细胞因子的分泌有明显的促进作用,且呈现浓度相关性,表现出明显的免疫活性;通过AAPH诱导的红细胞氧化性溶血模型对LZ1的抗氧化活性进行评价,发现LZ1有很好的抑制AAPH诱导的红细胞氧化溶血的特性。
A new polysaccharide LZ1 was isolated and purified using DEAE-Sepharose Fast Flow and Sephacryl S-200 HR from crude polysaccharide extract obtained from Ganoderma lucidum mycelium via hot-water extraction. The structure of LZ1 was identified and elucidated by gel permeation chromatography (GPC), scanning electron microscopy (SEM), ultraviolet spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, gas chromatography (GC), nuclear magnetic resonance (NMR) spectroscopy, periodate oxidation, and Smith degradation. The results showed that LZ1 was a homogeneous polysaccharide and did not contain impurities such as proteins and nucleic acids. The molecular weight (Mw) was determined to be 7498 u by GPC. LZ1 was an acidic polysaccharide and consisted of rhamnose, fucose, mannose, glucose, galactose, and arabinose at a molar ratio of 0.94:0.50:1.68:26.91:4.80:17.12. The main glycosidic linkage types were 1→4 and 1→2 or 1→6 and 1→3. Congo red test suggested that there were no triple helical structures in LZ1. The effect of LZ1 on the expression of tumor necrosis factor-α (TNF-α), interleukin 6 (IL-6), and nitric oxide (NO) was studied using murine macrophage RAW264.7 cells as an in vitro immunomodulatory model. The results showed that LZ1 significantly promoted the secretion of TNF-α, IL-6, and NO in a concentration-dependent manner, and exhibited excellent immunomodulatory activity. Evaluation of the antioxidant activity of LZ1 by a 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH)-induced oxidative hemolysis model in erythrocytes suggested that LZ1 could effectively inhibit the AAPH-induced oxidative hemolysis of erythrocytes.
金门高粱酒的风味及挥发性成分分析

- , 2018, DOI: 10.13982/j.mfst.1673-9078.2018.7.038
Abstract: 金门高粱酒是台湾省金门县生产的一种清香型白酒,金门岛的独特海岛气候可能对酒的香气质量产生影响,但目前尚未开展深入研究。为了分析金门高粱酒的香味特征,运用感官检验、顶空固相微萃取结合气相色谱-质谱联用(GC-MS)技术对金门高粱酒挥发性成分进行分析。感官评价分析出该酒的主要风味轮廓为醇香和果香。GC-MS分析金门高粱酒共鉴定出42种挥发性成分,包括酯类21种,醇类6种,醛酮类6种,烷烃类5种和其他类化合物4种,其中酯类物质主要是乙酸乙酯(2769.00 μg/mL)、己酸乙酯(1674.90 μg/mL)、辛酸乙酯(1353.30 μg/mL)、癸酸乙酯(621.00 μg/mL);醇类物质主要是3-甲基丁醇(301.80 μg/mL)和2-甲基丁醇(82.80 μg/mL);醛酮类物质主要是糠醛(114.00 μg/mL)、壬醛(34.50 μg/mL)和2-壬酮(17.70 μg/mL),该实验为深入研究金门高粱酒及其他清香型白酒的风味提供了数据参考。
Kinmen Sorghum liquor is a kind of light-aroma-type liquor produced in Kinmen county of Taiwan province. The unique island climate of Kinmen island may have an effect on the aroma quality of the liquor. In order to know the aroma characteristics of Kinmen Sorghum liquor, the volatile compounds were analyzed using sensory evaluation and headspace solid phase micro-extraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS). Sensory evaluation showed that alcoholic and fruity notes were the main flavor profile. And 42 volatile compounds, including 21 esters, 6 alcohols, 6 aldehydes and ketones, 5 alkanes and 4 others were identified using GC-MS. Among these compounds, ethyl acetate (2769.00 μg/mL), ethyl caproate (1674.90 μg/mL), ethyl octanoate (1353.30 μg/mL) and ethyl decanoate (621.00 μg/mL) were shown to be the main esters. 3-Methyl-1-butanol (301.80 μg/mL) and 2-methyl-1-butanol (82.80 μg/mL) were the main alcohol compounds. And furfural (114.00 μg/mL), nonanal (34.50 μg/mL) and 2-nonanone (17.70 μg/mL) were the main aldehydes and ketones compounds. The experiment provided data reference for the flavor study of the Kinmen sorghum liquor and other light aroma type liquor.
公民道德的应然逻辑:反身价值
,
- , 2013,
Abstract: 我国的公民道德教育长于灌输应该如何生活的理由,却拙于阐述“为何应该”。公民道德的反身价值是对“为何应该”的理性思考,也是公民道德教育必须予以重视的一般原理性问题。一个能对社会产生德性影响的公民一定是一个幸福、富有责任感的公民,而这样的公民也必然需要反身价值的支撑和保护。为此,学校道德教育需突显公民道德的反身价值,以此增强公民道德对公民的内在吸引力和对社会的精神导引力。
In our country, so far the civil morality education seems to be more inclined to indoctrinate people with “we should follow the moral conventions” than to enable them to understand “why we should do so”. The reflexive value of civil morality is the rational thinking of “why we should follow moral conventions”, and it is a basic problem that civil morality education has to resolve. A person who can generate moral influence on society must be a happy and responsible man, who also needs support and protection of reflexive value. Therefore, the school moral education should highlight the reflexive value of civil morality, which can strengthen the inherent attractiveness of civil morality and the spiritual guidance of society
