In addition, the recombination for large numbers of charge carriers would occur in the volume or on the surface of TiO_2. Therefore, the extension of the photoactive wavelength region of TiO_2 into the visible region and improvement of quantum efficiency are desirable for popularizing more TiO_2 photocatalyst, especially under solar light for industrial areas or poor interior lighting illumination in living spaces.

但纳米TiO_2具有较宽的禁带宽度，只能吸收太阳光中5%左右的紫外线，而太阳光中近45%的可见光在处理污染物中却得不到有效利用，因此太阳能的利用率较低，这就限制了其实际使用范围；另外，TiO_2半导体载流子的复合率较高，因此量子效率较低。

But Qoheleth's greatest trouble seems to be his inability to find a direct, smooth answer to life's riddles; hence he so frequently deplores the insufficiency of his wisdom; on the other hand, besides wisdom, commonly so called, ie the wisdom resulting from man's investigations, he knows another kind of wisdom which soothes, and which he therefore recommends again and again vii, 12, 20; Heb.

But in practical operating, overvoltage caused by reignition of the vacuum switching device frequently appears, and it result in damage of the capacitor bank or the switchgear itself. Ensuring the switchgear against reignition and installing a protective device are two main approaches to avoid the phenomenon. In this paper, a study on overvoltage caused by reignition due to capacitor bank switching with the vacuum switching device and its preventive measures are carried out. The main work which has been done and researches are as follows: 1. The producing mechanism of overvoltage and its influence factor are analyzed. It is pointed out that single-phase reignition is the main reason for damage of the switchgear and two-phase reignition is the main reason for damage of the capacitor bank,so overvoltage of single-phase reignition and two-phase reignition are the emphases of prevention. 2. Analysis of the special working condition of the operating switch for capacitor bank is carried out. It indicates that the vacuum switching device is difficult to realize no-reignition under this operation condition, so it is more practical to adopt protection devices. 3. Analyses of protection effect of RC and MOA and their shortages are carried out. It shows that the two methods can only restrain effectively overvoltage caused by single-phase reignition, and they cannot protect the capacitor bank when reignition of two-phase occurs. 4. The operation principle of G-R damping device is analyzed and discussed emphatically.

本文针对真空开关投切电容器组时因重燃而产生的过电压及其防治措施进行了研究，所开展的主要工作和研究结果如下： 1、对过电压的产生机理及其影响因素进行了分析，指出单相重燃是导致开关设备损坏的主要原因，而两相重燃则是导致电容器组损坏的主要原因，因此单相重燃和两相重燃过电压是防护的重点； 2、对电容器组操作开关的特殊运行条件进行了分析，指出在这种运行条件真空开关难于实现不重燃，因此采用保护装置更具有现实意义； 3、对RC与MOA的保护效果和存在的不足进行了分析，指出这两种方法均只能有效抑制单相重燃过电压，而不能在发生两相重燃时保护电容器组； 4、重点对G-R阻尼装置的工作原理进行了分析和讨论，指出该装置接入后线路中将会出现两种频率的高频振荡，而电容器组上的过电压是由这两种振荡共同决定的； 5、根据对上述两种振荡的分析指出存在一个最佳电阻值使得过电压最低，并提出了电容器组电压和最佳电阻值的近似求解方法； 6、使用电气暂态分析软件MATLAB对G-R装置的保护效果进行了仿真计算，证实该装置确实可以有效抑制重燃时的电容器组过电压； 7、根据仿真与近似计算结果的偏差提出了近似计算的修正方法，经过修正后的过电压计算结果与仿真结果吻合较好； 8、对G-R装置中放电装置G与阻尼电阻R的要求进行了分析，指出采用编织电阻和真空间隙可能是最佳选择。

日至时期的台南府城南门外地区，因为在日本政府的政令之下，开始大规模的迁葬，迁葬之因即为日本政府所实施的台南市都市计画，分为三个时期，萌芽期、开拓期、展开期，逐步的扩张台南市的都市范围，因此在取得土地的过程中，项城郊一代发展，台南府城南门外的墓葬区成为日至时期台南市南向发展的重心，经过坟墓迁移之后的土地，经过重新规划，行程教育、运动设施的专用地，日至时期台南府城南门外的墓葬景象，在透过日本政府的政治力量的迁葬之下，以及迁葬之后的建设，转变成学校与运动场，充满活力的区域。战争期间，因为战争需要，在台南府城南门外墓葬区的南侧建立台南军机场，因此在战争期间，台南府城南门外地区又带入军事的色彩，战后国民政府接收日本人撤退之后的所有建设，将空军后勤补给对进驻台南军机场，随之而来的眷属则占据日本人的宿舍，另外在新建多处的眷村，战后初期的眷村文化即进入台南府城南门外地区。

A practical charged membrane which prepared from the blends of sulphonated polyphenylene sulfide/poly can be considered as a 3D lattices. The experimental conductivity was related with a 3D simulation and the result showed the membrane has a transition from insulator to conductor at the ratio of charged components SPPS about 0.144. Obviously, this value falls in the range of a theoretical simulation for a 3D lattices.

由於实际的荷电膜也可看作为三维格栅体系，因此，可用三维格栅体系程序对不同荷电分率膜的电导数据进行拟合，结果表明，对於实际的磺化聚苯硫醚／聚醚碸共混膜，当荷电组分SPPS的分率达到0.144时，共混膜即会从不良导体变为良导体，显然该值落在理论值0.1~0.2，因此，理论模拟结果与实际荷电膜传质的实验数据相吻合。

用1，2-二乙烷与二十余种醛类作用，得到有固定熔点的晶体衍生物，它们的熔点分布在85—210℃之间，产率为40—96％，这试剂与甲基酮类在相同条件下无反应，因此，它可作为鉴定醛类的专属试剂。 2。上述衍生物用稀盐酸在室溫处理，能发生水解，可以定量地收回原来的醛，因此这试剂又可作为分离醛类的试剂。 3。上述衍生物可以用非水滴定法半微量地测定其分子量可作为鉴定醛类的另一项参考数据。 4.1，2-二乙烷与醛类能生成晶体衍生物，但这试剂也与甲基酮在同样条件下发生反应，所以不适合作为鉴定醛类的专属试剂。
