| 1 | 激光剥蚀信号在线平滑和去汞装置:原位微区铅同位素准确分析利器显示文摘激光原位微区分析可在微观尺度上完成样品的元素定量分析或同位素组成测定,为研究成岩、成矿物质来源和追踪地壳与地幔演化历史提供了独特的观察视野。但是,激光剥蚀等离子体质谱的一些缺陷阻碍了地质样品的高精度、高空间分辨率分析,比如:剥蚀池的位置效应、低剥蚀速率下信号波动影响、激光剥蚀脉动式信号导致的光谱螺纹效应、高频激光剥蚀造成的元素分馏效应等。为此,一些学者设计了不同规格和样式的激光剥蚀信号平滑装置来克服这些问题。但是,这些信号平滑装置普遍还存在气体吹扫时间过长和降低激光剥蚀信号灵敏度等问题。因此,研制新型的信号平滑装置对改善LA—ICP—MS的数据质量具有重要的意义。 | Hu Z Zhang W Liu Y Gao S Li M Zong K Chen H Hu S 刘勇胜 | 2015 | 矿物岩石地球化学通报2015，34，4： | 114 |

| 9 | Role of live microbial feed supplements with reference to anaerobic fungi in ruminant productivity: A review显示文摘To keep the concept of a safe food supply to the consumers, animal feed industries world over are showing an increasing interest in the direct-fed microbials(DFM) for improved animal performance in terms of growth or productivity. This becomes all the more essential in a situation, where a number of the residues of antibiotics and/or other growth stimulants reach in milk and meat with a number of associated potential risks for the consumers. Hence, in the absence of growth stimulants, a positive manipulation of the rumen microbial ecosystem to enhance the feedstuff utilization for improved production efficiency by ruminants has become of much interest to the researchers and entrepreneurs. A few genera of live microbes(i.e., bacteria, fungi and yeasts in different types of formulations from paste to powder) are infrequently used as DFM for the domestic ruminants. These DFM products are live microbial feed supplements containing naturally occurring microbes in the rumen. Among different DFM possibilities, anaerobic rumen fungi(ARF) based additives have been found to improve ruminant productivity consistently during feeding trials. Administration of ARF during the few trials conducted, led to the increased weight gain, milk production, and total tract digestibility of feed components in ruminants. Anaerobic fungi in the rumen display very strong cell-wall degrading cellulolytic and xylanolytic activities through rhizoid development, resulting in the physical disruption of feed structure paving the way for bacterial action. Significant improvements in the fiber digestibility were found to coincide with increases in ARF in the rumen indicating their role. Most of the researches based on DFM have indicated a positive response in nutrient digestion and methane reducing potential during in vivo and/or in vitro supplementation of ARF as DFM. Therefore, DFM especially ARF will gain popularity but it is necessary that all the strains are thoroughly studied for their beneficial properties to have a confirmed ‘generally regarded as safe' status for ruminants. | Anil K Puniya Abdelfattah Z M Salem Sanjay Kumar Sumit S Dagar Gareth W Griffith Monica Puniya Sreenivas R Ravella Nikhil Kumar Tejpal Dhewa Ravinder Kumar | 2015 | Journal of Integrative Agriculture2015，14，3： | 17 |
| 10 | Design of 16S rRNA gene primers for 454 pyrosequencing of the human foregut microbiome显示文摘AIM:To design and validate broad-range 16S rRNA primers for use in high throughput sequencing to classify bacteria isolated from the human foregut microbiome.METHODS:A foregut microbiome dataset was constructed using 16S rRNA gene sequences obtained from oral,esophageal,and gastric microbiomes produced by Sanger sequencing in previous studies represented by 219 bacterial species.Candidate primers evaluated were from the European rRNA database.To assess the effect of sequence length on accuracy of classification,16S rRNA genes of various lengths were created by trimming the full length sequences.Sequences spanning various hypervariable regions were selected to simulate the amplicons that would be obtained using possible primer pairs.The sequences were compared with full length 16S rRNA genes for accuracy in taxonomic classification using online software at the Ribosomal Database Project (RDP).The universality of the primer set was evaluated using the RDP 16S rRNA database which is comprised of 433 306 16S rRNA genes,represented by 36 phyla.RESULTS:Truncation to 100 nucleotides(nt)downstream from the position corresponding to base 28 in the Escherichia coli 16S rRNA gene caused misclassification of 87(39.7%)of the 219 sequences,compared with misclassification of only 29(13.2%)sequences with truncation to 350 nt.Among 350-nt sequence reads within various regions of the 16S rRNA gene,the reverse read of an amplicon generated using the 343F/798R primers had the least(8.2%)effect on classification.In comparison,truncation to 900 nt mimicking single pass Sanger reads misclassified 5.0%of the 219 sequences.The 343F/798R amplicon accurately assigned 91.8%of the 219 sequences at the species level.Weighted by abundance of the species in the esophageal dataset,the 343F/798R amplicon yielded similar classification accuracy without a significant loss in species coverage(92%).Modification of the 343F/798R primers to 347F/803R increased their universality among foregut species.Assuming that a typicalpolymerase chain reaction can tolerate 2 mismatches between a primer and a template,the modified 347F and 803R primers should be able to anneal 98%and 99.6%of all 16S rRNA genes in the RDP database.CONCLUSION:347F/803R is the most suitable pair of primers for classification of foregut 16S rRNA genes but also possess universality suitable for analyses of other complex microbiomes. | Carlos W Nossa William E Oberdorf Jφrn A Aas Bruce J Paster Todd Z DeSantis Eoin L Brodie Daniel Malamud Michael A Poles Zhiheng Pei | 2010 | World Journal of Gastroenterology2010，16，33： | 16 |

| 14 | Behavior of High Performance PVA Fiber Reinforced Cement Composites in Triaxial Compression显示文摘Based on an extensive experimental program,the paper studies the behavior of HPFRCC under triaxial compression. The experimental parameters are lateral confining pressure and PVA fiber content by volume. The test results indicate that ultimate strength and peak strain are significantly improved with the increases of confining pressure. The confining effect introduced by the fibers becomes minor in triaxial compression tests,where there is relatively high external confining pressure. The axial stress-strain curves with different confining pressure and different PVA fiber content by volume are obtained. Lateral confining pressure constraints the lateral expansion of HPFRCC,so there is a big plastic deformation with its ultimate strength improved. At lower confining pressure,PVA fiber content by volume has some effect on the decreased section of stress-strain curve. According to test results,the paper establishes formula of confining pressure with ultimate strength and axial peak strain respectively. | LI Y LIANG X W LIU Z J | 2010 | 武汉理工大学学报2010，32，17： | 10 |
| 15 | 胡萝卜软腐果胶杆菌巴西亚种(Pectobacterium carotovorum subsp.brasiliense)引起的黄瓜细菌性软腐病在中国发生显示文摘2014—2015年,在中国山东、山西、河北、河南、辽宁等省的黄瓜茎叶上发生了毁灭性的细菌性软腐病,造成了黄瓜产业严重的经济损失。黄瓜叶片、茎、叶柄和果实表面出现流胶;茎基部呈深褐色进而出现湿腐。受侵染的黄瓜叶边缘出现黄斑和湿腐症状,并逐渐扩散至叶片中心。从受侵染组织中分离出45个细菌菌株,在形态学特性鉴定、生理学、生物化学和16Sr RNA基因序列分析的基础上,将病原体鉴定为胡萝卜软腐果胶杆菌(Pectobacterium carotovorum)。多位点序列分析(MLSA)证实,分离菌株是胡萝卜软腐果胶杆菌巴西亚种[Pectobacterium carotovorum subsp.brasiliensis(Pcb)],病原菌归入进化枝II。重新分离获得与原始菌株相同的菌株,证实了分离菌株的致病力。寄主范围测试表明,该菌株具有广泛的寄主范围。目前为止,这是对Pcb引起的黄瓜软腐病——这一对黄瓜生产具有重要经济影响的病害在中国乃至全球范围内的首次报道。 | 冯志琴(译) meng x l chai a l shi y x xie x w ma z h li b j | 2017 | 中国植保导刊2017，37，7： | 10 |
