Was It Possible to Stabilise the Price of Wool? Organised Wool Marketing 1916 to 1970

Wool is the only Australian commodity for which there has been an attempt to organise price stability through a buffer stock scheme (1970–91). Growers pressed for the introduction of a scheme since the early 1920s. We test the veracity of claims that the sale of the stockpiles optimised growers' returns. We also simulate the likely outcomes of the reserve price schemes (RPS) proposed in 1925 and 1952, respectively. Our findings are that post-war stockpile disposals did not optimise wool growers' incomes, the undercapitalised proposed RPS of the 1920s would have collapsed in the depression, and that the post-1952 RPS would have been in considerable difficulty.     

SC针梳机铁炮结构优化

SC针梳机在腈纶毛条生产中控制单位长度毛条重量,对产品质量起决定性作用。针梳机匀整部位铁炮故障的频繁发生,直接影响毛条产品的产量和质量。根本原因在于零部件结构不合理及轴承型号不匹配。因此解决铁炮故障意义重大。     

Counting the cost: the reserve price scheme for wool 1970‐2001

This paper provides a policy commentary on the collapse in 1991 of the Australian Reserve Price Scheme for wool. A key cause of the collapse in the Scheme was a change in the RPS's governance arrangements, which led to increased political pressures to raise prices to unsustainable levels. In addition, in this paper an estimation has been made of the direct, upfront costs of the operation of the scheme, drawing on the financial accounts of the various agencies operating the RPS and subsequent wool stockpile. This was undertaken to determine the scale of the policy failure.     

Industry associations and non-competitive behaviour in Australian wool marketing: Evidence from the Melbourne Woolbrokers' Association, 1890–1939

From the 1890s the sale of Australian wool was organised through a series of regionally based associations of wool selling brokers and wool buyers. They engaged in cartel-type behaviour by price fixing and exclusive dealing. We ask the question whether the wool selling brokers exploited their monopoly power to thefull in setting fees and charges paid by the growers and buyers. Association records provide data on the pricing structure and rationale for changes. We surmise that the existence of the cartel lifted prices above competitive levels. However, the pricing behaviour was moderated to a strong form of limit pricing.     

影响羊毛横机织物热传递性能因素的研究

为了研究羊毛纤维横机织物热传递性能,分别对羊毛横机织物的未充满系数、厚度、单位面积干燥质量以及织物密度与导热系数的关系进行了研究与分析。结果表明随着羊毛织物未充满系数、织物密度的升高,导热系数λ逐渐减小,即织物热传递性能下降,而随羊毛织物单位面积干燥质量和织物厚度的增加,导热系数λ呈增加趋势,织物的热传递性能上升。     

农牧户兼业、规模异质与生产技术效率变化*——基于5省452户细毛羊养殖户的实证研究

［目的］利用5省452户细毛羊养殖户调研数据，分析规模异质下农牧户兼业化对细毛羊生产技术效率的影响。［方法］文章采用SBM模型和Tobit模型分别测算了农牧户细毛羊生产技术效率及不同规模下兼业化对生产技术效率的影响。［结果］（1）在其他条件不变的情况下，兼业化会显著促进农牧户生产技术效率的提升，且非农兼业程度越强对细毛羊生产技术效率的正向影响作用越大。（2）分规模来看，农业兼业形式对散养户、中规模和大规模养殖户生产技术效率具有负向影响，对小规模养殖户生产技术效率具有正向影响，但影响均不显著； 由于非农兼业形式在散养户和大规模养殖户中所带来的“劳动力流失效应”与“收入投资效应”的强度的不同，对散养户生产技术效率具有显著的负向影响，对大规模养殖户生产技术效率具有显著的正向影响。（3）受教育程度、养殖年限、养殖方式、是否接受技术培训均对养殖户总体生产技术效率具有显著的正向影响，年龄变量对养殖户总体生产技术效率具有显著的负向影响。［结论］应全面推进细毛羊标准化规模养殖进程，加大细毛羊养殖技术培训的开展与推广，加强对养殖专业合作社的法律宣传和政策引导，完善国家层面的畜牧养殖的扶持政策。     

絮凝法处理洗呢废水的实验研究

笔者采用絮凝剂单独对和毛油LY进行絮凝处理,实验加入生产中常用的肥皂和洗涤剂LAS模拟工厂洗呢废水。文章探讨了絮凝剂用量、时间、温度、pH值对絮凝效果的影响;通过研究得出和毛油、和毛油+肥皂、和毛油+洗涤剂絮凝的最佳配方,为实际应用提供参考。结果表明:单独和毛油絮凝时絮凝剂的用量较多,和毛油+肥皂、和毛油+洗涤剂混合溶液进行絮凝时,絮凝剂的用量较低。

中国羊绒产业出口贸易发展阶段及其特征

中国羊绒产业经历了40多年的发展历程，已经从第一羊绒资源大国逐渐发展成为世界羊绒生产、加工、销售和消费第一大国。但中国羊绒产业缺乏优势资源的整合，在资源布局、技术创新、出口战略、品牌创新等方面各自为政，尚未实现资金、产能、技术、人力、客户资源等方面的互补共享，难于形成特色资源的整合优势，从而不能以完整的产业链整体参与国际市场的竞争。
