电动助力转向系统直流伺服技术的研究

针对电动转向系统原有单一控制方式的不足，根据直流脉宽调制伺服系统工作原理，提出了一种带有助力和阻尼两种模式的综合控制方式。通过对两种模式分别进行分析计算，提出了一种针对占空比和控制模式的修正方法。台架性能试验验证表明，采用这种伺服控制方式，电动助力转向系统快速回正时的平稳性有所提高。

动物园兽医的使命及发展思路

野生动物的移地保护和保护教育是现代动物园的主要功能,兽医在保障野生动物健康方面承担着重要的使命。动物园兽医在本质上是医学的一个特殊分枝,由于野生动物及其疾病种类的复杂性和个人精力、能力的局限性,动物园兽医的职业化和专业化是提高野生动物健康保障能力的根本出路;应激因素对圈养动物的健康造成很大的威胁,而适度驯化则可以最大限度地减少应激的发生;在国内建立区域动物园兽医服务网络、建立兽医行业内部信息交流平台是提高动物园兽医行业整体水平的基本思路：正确的疾病诊断和规范的处方,以及全面关注动物的基本需求、积极主动的疾病防疫等在兽医日常工作中占有同等重要的地位。由于兽医掌握了动物发病和死亡的第一手资料,动物园应当为兽医参与动物管理提供条件。     

Private native forest policies in New South Wales,Queensland, Victoria and Tasmania

Private native forests in Australia perform a dual production and conservation role, providing an important source of timber, and complementing formal conservation reserves. A comparison of policies for private native forests in New South Wales, Queensland, Victoria and Tasmania illustrates the scope for timber harvesting, the provision for environmental values, and initiatives for responsible and sustainable forest management. The sustainable management of Australia’s forests requires initiatives by both government and landowners to accommodate changes in community attitudes, new management strategies, integrated catchment management principles and both commercial and non-commercial opportunities for forest use. Of all of the Australian states, New South Wales has the most restrictive laws in terms of forest management and harvesting. Queensland and Victorian legislation have a more commercial focus, while Tasmania has a balance of both environmental and commercial objectives. The duty of care for private native forests is a responsibility that falls to the landholder, and while this should be enforced by legislation, the private provision of community benefits requires both recognition and reward. The presence or absence of incentives potentially determines the effectiveness of forest codes of practice.

How to foster good husbandry of private native forests

It is generally agreed that effective conservation requires the cooperation of private landholders to complement reserve-based efforts, but there is little agreement about how this can best be achieved. Various stakeholders lobby for tough regulations, for greater landholder freedom, and for incentives for activities or outcomes. A review of these alternatives suggests an emerging consensus that incentives are the most effective approach. Policy-makers should consider incentive-based approaches such as stewardship support to foster conservation outcomes on private lands.
