Second, most of the content of the assigned chorus piece were chosen to meet to the elementary students' musical abilities. The form was referred to as AB; two parts songs were usually selected; the meter signature was referred to as quarter note gets one beat and beats can be grouped in twos or fours, it remained stablely in the whole tune; the tempo of assigned chorus piece almostly based on "Moderato" and "Allegretto"; the tonality are combined with the major and minor scales and also present as the pentatonic scales, the minor scale were rarely used.

二 、九十二至九十六学年度国小合唱指定曲的内容，大部分与国小音乐能力指标相符：乐曲曲式明确，以二段式居多；编制以同声二部为主；拍号以单拍子的二拍、四拍为主，少有拍号变化；速度以中板、稍快板为主；调性不完全偏向大小调乐曲，仍兼顾调式乐曲，转调变化的不多，小调乐曲较少出现。

The former researches on land price, usually treating spatial structure change as astatic one, often use Hedonic Model to depict the spatial variety of the whole studyarea. This research method hypothesized that the error items were dividedindependently and equally.

过去关于地价的研究主要视地价的空间结构变化为静态，多以特征价格方程等方法全域刻画地价空间变化，将误差项假设为独立与相等的分配，这样所得到。

In this paper, the change rule of inner oil temperature in wet multiple disk brake is studied when braked. Mathematics model on unsteady state heat transfer is established in wet multiple disk brake On the basis of theory and experiment research, which will provided theory ground for design and choice type on wet multiple disk brake.

We performed a simulative test, which confirms that wavelet analysis can separate annual wobble and Chandler wobble. Our results show that this method can be used in astronomical geodynamies effectively. This paper is divided into two parts. The first is about statistic characteristic of polar motion. Polar motion includes secular motion, long period fluctuations, Chandler wobble, annual wobble and high frequency wobble. The secular motion is 3.4mas/year and towards 760W meridian. Long period fluctuations have difference periods in x-axis and y-axis. They are 31.7-year and 24-year in x-axis and 28.5-year and 22.9-year in y-axis. These 2~? decades fluctuations have an amplitude of about 30 mas , and are very nearly linearly polarized, with the observed motion of pole being almost entirely along a line between 360E and 1440W. There is a 55.4-year wobble whose amplitude is 9 mas. The amplitude of the interannual fluctuations is about 4? mas. The amplitude of long period fluctuations decreased after 1970. The annual wobble is a steady wobble. It retrograde wobble is only 1/20 of prograde wobble in amplitude.

本文的工作主要分为两部分：第一部分是通过分析POLE97序列，我们对极移的统计特性有了一个较全面的认识，极移主要包括趋势项、长周期项、Chandler项、周年项和高频项：趋势项的方向是西经76°，速度为每年3.4mas；长周期项中Markowitz 项在X、Y两个方向有不同的周期，它们分别是：X方向的两个周期是31.7年和24 年，Y方向的两个周期为28.5年和22.9年它们叠加在一起是一个线偏振运动，最大振幅约为30mas，偏振方向在西经144°和东经36°之间；极移的长周期波动中还存在一个 55.4年周期的圆周运动，振幅约为9mas；十年尺度变化的振幅在4～6mas之间，在Y 方向十年尺度的成份比较多，它们的周期在X方向和Y方向不是对应的；从七十年代年开始长周期变化的振幅明显降低；周年项是一个振幅稳定的摆动，在X、Y两个方向的振幅略有差别，逆向运动振幅大约为顺向运动振幅的1/20；Chandler摆动的振幅自1900年以来经历了几次较大的变化，其中包括1915年和1955年两次极大值，振幅分别达到0&。25和0&。28，以及1925～1940期间小于0.09的过程，Chandler项在X、Y 两个方向的振幅几乎完全相等，其逆向运动振幅不到顺向运动振幅的1/50。

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
