The results are as follows:1 among three kinds of Chysopa peral. of the compound eyes show little daily change in Chrysopa sinica Tjedar .The model and color of psesudpopupil show significant daily change in Chrysopa septempzhbybimctata Wesmacl and Chrysopa formosa Brauer, color and diameter of the psesudpopupil of the compound eyes in Chrysopa septempunctata Wesmacl make rapid change at noon, afternoon ,night are similar ,but make little change in the morning and the next morning. Diameter of psesudpopupil of compound eyes is the biggest in the afternoon, which of Chrysopa formosa Brauer, is the biggest at noon.
本文应用光学及电生理学方法对棉铃虫优势种天敌—中华草蛉、大草蛉和丽草蛉3种草蛉的感光和趋光机制进行了研究,主要研究结果如下: 1、中华草蛉、大草蛉、丽草蛉复眼伪瞳孔大小、颜色昼夜间有节律性变化,且种间具有不同的变化模式。3种草蛉中,中华草蛉复伪瞳孔大小昼夜节律变化不明显,其模式和颜色上亦基本无变化,中间为一小黑点,其外围是绿色,最外层为红色,形状为正六边形:大草蛉、丽草蛉的复眼伪瞳孔大小昼夜间不同,大草蛉的复眼伪瞳孔在中午、下午、晚上变大,早晨和次日早晨基本一致,但次日早晨稍小些。

House, Nanyang, He′nan 473006, ChinaAbstract: The change rate of different trace component of the same material varied in the fermentation of yellow rice wine, samely, the change rate of the same trace component of the common materials varied in daily yellow rice wine production and its characteristics are: 1.The change rate in millet, indica rice and semi-glutinous rice, Zn the highest, then Mg, and Cu and Se the lowest. 2.The change rate in glutinous rice, Mg the highest , then Zn, then Cu, and Se the lowest.

NodD binds to and bends target promoters through anchoring two tandem and individual specific DNA sites. NodD functions as a tetramer, which has a V-shaped main body. Tetrameric NodD is to change its own conformation rather than its oligomeric forms in response to small signal molecules. The specific interaction between each NodD DNA-binding domain and each specific DNA site does not alter itself in spite of naringenin induction, and the induced conformational change is transferred from protein to DNA. Only the DNA conformation incited by induced NodD is competent for RNA polymerase to form the transcriptional open complex. It cannot be excluded that NodD may have protein-to-protein contacts with RNA polymerase, and that the NodD conformational change may also directly contribute to the transcriptional open complex formation. However, the NodD conformational change itself cannot serve as the determinant of the transcriptional molecular switch.
通过研究,我们提出了初步的NodD操纵子激活模型:第一,四聚体是NodD蛋白的功能单位,它通过铆钉两个串联的相对独立的DNA靶位点结合被诱导的启动子;第二,小分子配基的结合是改变NodD四聚体的构象而不是引发不同形式的寡聚体,在我们的模型中,NodD四聚体缩小其V形主体的弯折角,进而缩短其DNA结合功能域的间距;第三,小分子信号的诱导并没有改变NodD的DNA结合域和其DNA靶位点的相互作用,NodD的构象改变由蛋白质经其双铆钉位点传递给DNA;第四,只有诱导状态的NodD激发的DNA构象才能有效地使RNA聚合酶形成转录开放复合物;第五,不排除NodD与RNA聚合酶可能有直接的相互接触位点,不排除NodD构象的改变可能直接有利于RNA聚合酶形成转录开放复合物,但是我们认为NodD构象改变本身不是充当转录激活开关的决定因素。

The experimental results suggested that there were some rules during the fermentation as follows: pit temperature increased rapidly and then dropped at the beginning of the fermentation and kept stable eventually at 20~22 ℃; there was slight change in yellow water pH value at first and then pH value decreased gradually in middle fermentation stage and finally kept stable; the change rules of total acids of yellow water were opposite to pH change rules; the reducing sugar of yellow water increased at first and then dropped and kept stable eventually; there was almost no change in alcohol content of yellow water in prior fermentation period, and then it increased rapidly and dropped slowly and finally kept stable; gas production rate was as high as 550 L/d within the first week in fermentation and then dropped undulatingly and changed to zero or even negative gas production rate.
窖池温度在发酵前几天迅速升高,然后下降,最后趋于稳定,保持在20~22 ℃;黄水pH开始变化不大,中间逐渐下降,最后趋于稳定;黄水的总酸变化与pH相反;黄水中还原糖先升高后下降,最后基本保持稳定;黄水中酒精含量在发酵前期变化不大,后期先是迅速升高,然后缓慢下降,最后趋于稳定;在发酵前期一周内,产气量很大,最高达550 L/d;之后产气量呈波动式下降并逐渐平稳,最后趋于零甚至负产气量。

Therefore, the paper discusses how to resolve it. First, we should change the idea of education and promote the teachers" change from inculcating knowledge to facilitating the development of students. Second, we should improve the teachers" professional development and advance the teachers" change from pure curriculum executants to researcher and constructors. Third, we should emphasize the function of curriculum evaluation to develop education and promote the teachers" change from ultimate and only judge to stimulators of students natural development.
