Prior research on capital structure by Titman (1988) utilizes structural equation models to find out the determinants of capital structure. In this paper, we use the same methodology and add another endogenous variable – stock return to construct two equations. One regards capital structure and the other one regards stock returns.

Titman (1988)曾利用求解结构方程模式的统计软体–LISREL找寻影响公司资本结构的隐藏因子，本文乃以此篇论文为基础并加以延伸，除了纳入原先的内生变数资本结构外，再加入另一个内生变数–股票报酬率来建立一个双向影响的结构联立方程式，以期研究资本结构与股票报酬率两者是如何交互影响，并是如何由许多因子所共同决定。

研究了显色时间和显色温度对多酚总量检测的影响，实验证明，显色温度和显色时间对绿原酸标准溶液的吸光度影响较大，而对烟草样品溶液影响较小。

The concentration of NO and NO2 increases with increasing of frequency and increasing of the distance between electrodes. Electrode polarity unconspicuously affects the concentration of NO and NO2. The distance between electrodes considerably affects radio of NO2 /.

结果发现：放电频率、电极间距对NO 和NO2的浓度影响显著， NO 和NO2浓度随放电频率和放电间距的提高而增加，电极极性对NO 和NO2浓度的影响不明显，电极间距对 NO2 /的比值影响明显。

During the establishment of sediment yield dynamic model at the watershed outlet, it was difficult for us to carry out dynamic monitoring of each impact factors in the whole basin, because it was a long time research and was in very large-scale watershed. Taking into account the interannual variability of sediment yield mainly affected by hydrological conditions of rainfall - runoff and underlaying surface changes caused by soil conservation measures, a combined influence factor which is related to surface runoff modulus and the implementation time of the water and soil conservation project was proposed for the first time. Furthermore, its specific expression was determined through dimensional analysis and non-linear regression multianalysis.

在流域输沙量动态模型的建立中，由于研究时段长、研究流域尺度大，对输沙量各影响因子进行全流域逐年动态监测十分困难，考虑输沙量的年际变化主要受降雨-径流水文条件和水土保持措施等土地管理活动的影响，首次提出与地表径流模数和治理时间相关的综合影响因子，并通过因次分析法和二元非线型回归法确定了具体的表达式。

In this thesis, we find that dlg is indispensible in the establishment of anterior-posterior and dorsal-ventral polarity of drosophila oocyte. Removal of Dlg function from the posterior follicle cells using the FLP/FRT system leads to disruption of oocyte skeleton reconstruction that is elicited by the failure of those posterior cells to differentiate normally in mid-oogenesis. We demonstrate that abnormity of Notch, JAK-STAT and EGFR signal pathway in dlg mutants contributes to this aberrant differentiation. dlg null mutant also blocks the normal differentiation of two groups of anterior follicle cell-stretched cell and centripetal cell, but not border cell, with a lower penetrance. However unlike the result in posterior follicle cells, Notch and JAK-STAT signaling are both undisrupted in all mutant anterior follicle cells, implying other fate determinants may be involved.

我们的研究发现，后端滤泡细胞中的Dlg在果蝇卵子发生中期卵母细胞前后轴和背腹轴建立过程中也是必须的，PFC中dlg完全缺失型突变引起PFC的分化异常，导致卵子发生中期卵母细胞骨架重组异常，Stau、Grk等极性决定蛋白定位错误。dlg突变阻碍了Notch、JAK-STAT、EGFR等调节PFC分化的信号通路的激活。dlg突变的PFC也没有获得前端滤泡细胞命运。dlg突变不影响前端滤泡细胞群中边界细胞的分化，但是在一定程度上影响伸展细胞和向心细胞的分化，并且这种影响不依赖于前端滤泡细胞Notch或JAK-STAT信号激活的异常。

The relationship between the tracking error and those auxiliary errors is clearly established when plant relative degree is greater than one and therefore, it can be proved that the influence of averaging filters on a VS-MRAC system can be considered as, in a sense, an unmodelled dynamics. As a result of this, it is shown that the stability analysis of a signal synthesis based VS-MRAC system must be modified to include the 'unmodelled dynamics'.

当对象建模部分相对阶大于1时，得到了系统跟踪误差和辅助误差间明确的关系表达式，进而证明平均值滤波器对系统的影响相当于未建模动态对系统的影响，这表明以往相关文献关于系统稳定性的分析是有缺陷的，没有将平均值滤波器对系统稳定性的影响完全考虑在内； 3。

He also goes into the "Oh, let's protect all the little children" argument:"And let's not forget the bad influence those pictures have exerted on Chinese Internet users which include not only adults but children too," he said, saying that the picture would do "unredeemable damage" to children...

他也提到了&让我们来保护所有的孩子！&的这个讨论：&我们也不要忘记了这些照片所带来的负面影响对中国网名的影响，这些人里既包括大人，也有孩子。&他说这些照片会对孩子产生不可挽回的负面影响。
