The results show that the hal＆daily and half-monthly tidal wave perio- dicity changed abnormally about one month before the earthquake, with periodicity disappearing and amplitude reducing, but they recovered after it with clearer state than that at normal time.

分析了在2004年12月26日印尼8.7级地震前河北昌黎台记录到的自然电位及电场异常，结果显示昌黎台自电位、电场正常时段观测到的半日、半月潮汐波周期变化在震前1个多月发生畸变，周期消失，变化幅度相应减小，震后快速恢复，且潮汐波记录比震前正常时段更加清晰。

Part 3:The effect factor analysis reasarch on Swine breederBy using of structural equation modeling and combining with theory of plained behavior to analysis breeders\' quality behavior,and find out that only if increase swine breeders\' quality decision behavior through moral liability、income expection,and characteristics、relative behavior ect can get to the end,and it\'s very necessary to increase swine breeders\' quality cognive control capacity simultaneity.

研究发现，垂直协作的紧密程度对养猪户质量控制行为的确存在显著影响。除此外，其他诸多影响因素中，还包括农户养殖经验、有无生猪治疗和防疫记录、是否干部、参与合作组织与否、养殖培训和质量安全政策法规认知程度等均随着农户养殖规模的变化而发生变化，且影响较为明显。

In this paper, a full flow model is given for calculating the average residence time of molten steel in non-symmetry multi-strand tundish to analyze flow pattern, the model is as follow:〓 The model can be used to calculate the volume fraction of the dead area、the piston flow and the mix flow, and is satisfactorily applied to the water model of three-strand tundish of Guangzhou Steel Works to analyze the data of the experiment.

本文认为在研究中间包内高温钢水的流动问题时，应该考虑钢水密度变化这个条件对钢水流动的影响，这样其结果更符合实际钢水流动规律。本文针对非对称多流中间包，提出了全流量模型计算多流中间包钢水平均停留时间：〓该模型也能够很好地计算多流中间包的死区、活塞流区、全混流区体积分数。

The results suggested that the activities of these enzymes quickly enhanced at 1 d, 3 d, 5 d and 7 d after inoculation by injecting conidia of the false smut fungus at 7-10 d before heading in the resistant cultivars, but slower increase in the susceptible cultivars, and also showed that there was correlations between the cultivar resistance to the disease and the three enzymes.

结果表明，在抗病品种中苯丙氨酸解氨酶、过氧化物酶和多酚氧化酶3种酶活性接种后迅速提高，变化幅度较大；而感病品种的酶活性在接种后缓慢增加，变化幅度小。由此说明，这3种防御酶与水稻抗稻曲病有一定的关系。关键词水稻；稻曲病；防御酶
