金融支持“两牛”产业发展研究——以内蒙古兴安盟为例

兴安盟深入实施肉牛奶牛产业“双百千亿”工程,2019年以来,兴安盟金融系统持续加大对“两牛”产业的有效金融供给,在补短板、强弱项、延链条方面发挥了重要的支撑作用。但现阶段有效的金融支持手段仍显不足,究其原因是由于牛产业链自身薄弱,保险业和担保业发展缓慢、补充支持作用不强等制约金融投入因素的存在。需要补齐短板,建立风险分担机制,“点线面”多维度优化金融服务,提升金融集聚效率,助力“两牛”产业高质量发展,促进产业结构调整和优化升级,推动一二三产业融合发展,实现全面乡村振兴。

武陟县“两牛”、羊产业链发展现状、存在问题及对策建议

近年来,武陟县“两牛”、羊产业发展始终存在标准化水平不高、规模化程度较低、抗风险能力较差、缺乏核心竞争力、发展速度缓慢等问题,通过对该县“两牛”、羊产业链发展现状进行深入细致的调研,以期将“两牛”和羊产业发展情况摸透、问题找准、对策提实,推动该县畜牧产业高质量发展。

奶牛“两病”检疫阳性牛不同扑杀方法的探讨与体会

近年来,随着奶业的发展,奶牛养殖数量的急剧增加,造成奶牛跨区流动频繁,牛结核病和布氏杆菌病呈逐年上升的趋势,根据《动物防疫法》、《牛结核病防治技术规范》和《布氏杆菌病防治技术规范》的要求,乌鲁木齐市从2007年开始至2010年,对奶牛"两病"检疫检出的358头阳性牛及时扑杀,消灭传染源,最大限度地控制了"两病"对畜牧业及公众健康造成的危害。笔者总结了近年来采用不同扑杀方法扑杀病牛方面的工作体会,供同仁们参考。

Investigation on Liquid Holdup in Vertical Zero Net-Liquid Flow

Zero net-liquid flow (ZNLF) is a special case of upward gas-liquid two-phase flow. It is a phenomenon observed as a gas-liquid mixture flows in a conduit but the net liquid flow rate is zero. Investigation on the liquid holdup of ZNLF is conducted in a vertical ten-meter tube with diameter of 76 mm, both for Newtonian and nonNewtonian fluids. The gas phase is air. The Newtonian fluid is water and the non-Newtonian fluids are water-based guar gel solutions. The correlations developed for predicting liquid holdup on the basis of Lockhart-Martinelli parameter are not suitable to ZNLF. A constitutive correlation for the liquid holdup of vertical ZNLF was put forward by using the mass balance. It is found that the liquid holdup in ZNLF is dependent on both the gas flow rate and the flow distribution coefficient.
