NUMERICAL CALCULATION FOR 2-DIMENSIONAL HEAT TRANSFER IN KEYHOLE LASER WELDING

引用

Chinese Journal of Mechanical Engineering 1998年第3期11卷 20-25页

作者： Xu Jiuhua Zhang Jingzhou jiang Chengyu Luo yumei Mechanical Engineering Institute, Nanjing University of Aeronautics and Astronautics Nanjing Univ of Aeronautics and Astronautics Nanjing China

A numerical method is presented for analysing 2 dimensional quasi steady state heat transfer in high power density laser keyhole welding processes. The mathematical model is established according to the conservation of mass, momentum and energy. Computation is performed by using the finite control volume method in the curvilinear coordinate system. A position prediction correction procedure is employed to identify the solid liquid interface location. This method is applied to the study of a typical keyhole welding process of an AISI 304 stainless steel plate and its feasibility is verified.

为探究苯丙噻二唑(benzothiadiazole,BTH)处理对葡萄生长过程中果实氨基酸积累及其降解代谢的影响,以‘霞多丽’葡萄为实验植株,果实转色期喷施50 mg/L BTH,花后60 d开始每10 d采集1次样品直至果实成熟(花后110 d),使用高效液相色谱法、氨基酸自动分析仪、固相微萃取联合气相色谱-质谱联用仪分别分析果实的葡萄糖、果糖、蔗糖、有机酸和氨基酸含量,以及氨基酸降解代谢相关酶活性和相应香气产物。结果表明:谷氨酸、精氨酸和脯氨酸是‘霞多丽’葡萄果实的主要氨基酸,BTH处理可促进果实氨基酸积累,抑制果实葡萄糖、果糖和蔗糖生成,提高成熟果实的酒石酸和柠檬酸含量,降低苹果酸含量;同时,BTH处理抑制了果实游离态支链脂肪族香气化合物的生成,增强了成熟葡萄的氨基酸转移酶(aminotransferase,AT)、醇酰基转移酶(alcohol acyltransferase,AAT)和丙酮酸脱羧酶活力,改变了氨基酸总量与乙醇脱氢酶活力的相关性及AT和AAT活力与单糖和有机酸含量的相关性,进而影响了氨基酸代谢香气物质的生成。研究结果可为BTH调控葡萄品质的应用提供理论指导及实践依据。

作者： yumei jiang Xiang Shen Xiaoping Wang Wenjie Li Department of Neurology First People's Hospital of Shanghai Jiao Tong University Shanghai 200080 China

In the present study, we compared explicit memory performance, using the Wechsler Memory Scale and implicit memory performance, using the Nissen software version of the serial reaction time task, in patients with Wilson＇s disease to normal controls. The Wilson＇s disease patients exhibited deficits in explicit memory tasks, such as figure recall and understanding memory. Moreover, the Wilson＇s disease patients exhibited deficits in implicit memory tasks, including significantly prolonged response times. These findings indicate that Wilson＇s disease patients have explicit and implicit partial memory impairments.

采用熔融共混法分别制备了凹凸棒黏土质量分数为1%、3%和5%的纳米凹凸棒黏土(ATT)/聚乳酸(PLA)复合材料,研究了ATT对PLA结晶性能和热稳定性能的影响。结果表明,ATT与PLA基体具有较好的相容性,当ATT含量低于3%时,可以均匀的分散在PLA基体中,而达到5%时则会发生团聚。FTIR结果表明,ATT与PLA基体之间存在较强的相互作用。ATT可明显促进PLA的结晶,起到异相成核的作用。ATT纳米颗粒的添加引起了PLA冷结晶峰向低温方向移动,使冷结晶温度从114.4℃降低至103℃左右。含ATT体系结晶速率比纯PLA快,表明ATT的加入可以促进PLA的结晶,说明ATT是PLA有效的成核剂之一。添加ATT可明显加快PLA的结晶速率并减小球晶尺寸。当添加3%ATT时,ATT/PLA复合材料的热分解温度比纯PLA提高了11℃,这主要是由于ATT/PLA网络密度的提高,使ATT在PLA的降解过程中能够起到较好的阻隔作用,抑制了PLA的降解自加速过程。

Extracts from Chinese Seabuckthorn Berry Have Antimicrobial Activity in vitro

引用

Agricultural Science & Technology 2016年第6期17卷 1277-1280,1284页

作者： Ruojun DING Yang BI Jixin LI yumei jiang College of Food Science & Engineering Gansu Agricultural University

Chinese seabuckthorn berry contains functional components. The berry was extracted by ethanol-water solution. MTT assay and growth rate method were applied to determine antibacterial ability in vitro of the extract solution. The antibacterial and antifungal assay indicated that the extract exhibited different degree of inhibitory activity. The result showed that the extract at a concentration of 1 250 mg/L had the maximum inhibitory effect against Escherichia coli, Bacillus subtilis, and Staphylococcus aureus. Inhibitory effect against B. subtilis was much larger than that against the other two bacterial species. MIC values(minimum inhibitory concentration) of the extract on three bacterial species were 5 000, 1 250, and 1 000 mg/L respectively. IC_(50)(50% inhibiting concentration) evaluation of Trichoderma viride, Rhizopus stolonifer, Aspergillus niger, Penicillium expansum, and Vintage Red indicated that the berry had the strongest inhibitory effect against P. expansum(5 520 mg/L), while it had the weakest inhibitory effect against R. stolonifer(18 870 mg/L). The results proved that seabuckthorn berry had highly effective and comprehensive antimicrobial function.
