The ancient amber artifacts of the Han Dynasty (202 BCE–220 CE) by using Fourier transform infrared spectroscopy to confirm their origins. 对汉代(公元前202年-公元220年)的古代琥珀制品采用傅里叶变换红外光谱法分析以确认其来源。

Picture of the original Tam Kung Temple dated 1877-1911 at Government and Fisgard streets. In 1911, the Yen Wo Society built a new three-storey brick building and installed the Tam Kung temple on the top floor. The temple honours Tam Kung, the god of seafarers. Picture kept in the meeting room of the Yen Wo Tsung Tsin (Hakka) Society. Photo taken on May 9, 2012.

Amber has been well documented since the Han Dynasty as a precious material many amber artifacts have been unearthed from tombs of Han Dynasty in China, It is generally believed that amber raw materials and some already-made artifacts may come from Europe (Baltic Sea) and Myanmar during the Han Dynasty, so amber and its artifacts are considered as a vital material and hard evidence of cultural exchange between ancient China and abroad. However, the analysis of excavated amber by using scientific methods is still limited so far. This paper applies Fourier transformed infrared spectroscopy (FTIR) to characterize several pieces of amber ornaments excavated from the tombs of Han Dynasty in central and southern Hunan Province and the results indicate that most of the ornaments were made of raw materials from Myanmar but also one Shuang Sheng amulet made of Baltic amber, Amber artifacts undergo significant deterioration during burial and exhibition, and varying degrees of deterioration and the presence of sedentary attachment may affect the results of infrared spectra of amber, which in turn interferes with the study of tracing the origin of the amber raw material. A preliminary study of amber and ornaments made of various gemstones and glass could reveal that the Hunan Province has influenced by both the Northern Steppe Silk Road and Southern Maritime Silk Road during the Han Dynasty and that in-land trade flows in this region were complex and diverse, and some amber ornaments may have been produced locally by exotic materials. More scientific data and analysis will support the study of ancient trade and cultural exchange during ancient time on a larger scale.

The image data set of various factions of Chinese ceramics, which is crawled and preprocessed from Baidu pictures, contains a total of 18,295 pictures and labels, including blue and white porcelain, pastel porcelain, Linglong porcelain, color glaze porcelain (four famous porcelain), other porcelain, purple pottery, purple clay pottery, laurel pottery, Anpottery (four famous pottery), other pottery, a total of 10 categories.The data set includes two parts: training set and test set. 10 pictures of class objects are stored in folders with corresponding numbers (0-9). Among them, the training set is divided into 10 chunks according to 10-fold cross-validation.

Irrigation with saline water is increasingly popular for reclaiming saline-alkali soil and for increasing crop productivity in some countries and regions. The purpose of this study was to investigate the alteration of salt ions distribution within different soil aggregate fractions after irrigation with freezing saline water. The experimental site is located on the coastal plain in Haixing County, Hebei Province, China. In a field experiment after irrigation with freezing saline water for 6 years, soil samples (0-10, 10-20 and 20-30 cm depths) were collected from three treatments: freezing saline water irrigation with plastic film mulching (IM); freezing saline irrigation without plastic film mulching (IO); and no saline irrigation and no mulching (CK). The bulk soils were separated into five size classes (i.e., 5-8, 2-5, 1-2, 0.25-1 and <0.25 mm) by the dry-sieving method. Then, the salinity and ion (i.e., Ca2+, Mg2+, K+, Na+, HCO3-, SO42- and Cl-) concentrations within each aggregate size class were determined following the methods of Lao (1988). The total salt content was calculated as the sum of the cations and anions. 咸水灌溉可以作为一种改良盐碱地和提高作物生产力的技术越来越受重视。本研究旨在研究多年冰冻咸水灌溉后不同土壤团聚体组分中盐离子分布的变化。咸水结冰灌溉试验位于河北省沧州市中科院海兴盐碱地资源高效利用研究基地，研究开始于2008年，试验设对照CK（无灌溉无覆膜CK）、灌溉无覆膜（IO）、灌溉和覆膜（IM）三个处理，三次重复；小区面积40m2。冰冻咸水灌水量为180mm，灌水时气温-10.3℃；覆盖地膜于3月土壤表面冰层融化且入渗完成后。土样采集工作于2014年4月，每个小区分层取原状土壤，层次：0-10cm，10-20cm，20-30cm；在实验室分别测定土壤团聚体和含盐量。每个小区两个重复。土壤干团聚体的测定：采用干筛分法。土壤分级为5.0, 2.0, 1.0和 0.25 mm系列样品筛，每一粒级的土壤收集称重计算百分数。土壤含盐量的测定：采用土/水比1:5进行浸提，浸提液用化学滴定法测定，其中HCO3-含量用双指示剂滴定，Cl-含量用AgNO3滴定，SO42+含量用EDTA间接络合滴定，Ca2+和Mg2+含量用EDTA滴定，K+和Na+含量用阴阳离子平衡法求得，再以各阴阳离子的浓度之和求得总含盐量。

Description Magi Open Information Extraction Dataset (MOIED) is a Chinese Open IE dataset containing 7,618,181 records extracted from plain text across 3,319,763 webpages in various domains. Each record in the dataset consists of the (subject, predicate, object) tuple, the associated confidence score, and the context information. The dataset comprises 1,427,742 distinct facts of 272,522 entities and 117,731 predicates. A notable property of MOIED is that each distinct fact has multiple records with URLs referring to mentions in diverse contexts, which enables multiple-instance learning (MIL) and other correlative approaches. As a paragraph level Open IE dataset, at least 45.1% of the records in MOIED can only be extracted through synthesizing information from multiple sentences. Magi is an extraction engine that continuously learns from the Internet, which combines cross-referencing, timeline analysis, and other heuristics to mitigate the inevitable false positives in the extractions. All records in MOIED were randomly sampled from a database dump of magi.com in January 2020. To provide more reliable evaluation results, human annotators examined the dataset and selected 19,161 verified records for the dev and test sets. Disclaimers The dataset is expected to be used in weakly supervised scenarios since the records in the training set are not human-annotated and could be imprecise or erroneous. Records are not guaranteed to be universally correct. The correctness of extractions should be evaluated based on contexts (specified by the URLs). The extraction was made at a certain time Magi visits the URL, thus it is not guaranteed that the URL is still accessible, or the content is unmodified since the extraction was conducted. Due to legal and regulatory issues, the webpage URLs are mostly ones accessible from Mainland China, yet, the content of certain webpages, as well as the extraction results, could be in violation of law and regulation of certain countries or regions in certain ways. This dataset contains content from the Internet, for copyright reasons, please do not redistribute or use it for non-research purposes.
