In order to improve the power quality of distribution network system, one of the most effective methods is reactive power compensation. In this paper, the Distribution Static Synchronous Compensator for reactive power compensation was studied, and then the digital controller based on One-cycle control was designed. The waveforms of experimental device based on DSTATCOM of one-cycle control were given in this paper. It can be seen from the results that the fluctuation of DC capacitor voltage is lower, the dynamic response speed of DSTATCOM providing or absorbing reactive power is fast, and the accuracy of steady-state compensation can achieve the requirements of reactive power compensation in engineering basically

为了提高配电网系统的电能质量，对无功功率进行精确补偿是非常有效的方法之一；本文研究了配电网静止同步补偿器用于无功补偿，并设计了单周控制的数字控制器；文中给出了基于单周控制的DSTATCOM无功补偿试验装置工作过程中的波形曲线，从试验结果可见，本文设计的单周控制DSTATCOM无功补偿装置的直流侧电容电压在工作过程中波动较小，装置发出或者吸收无功功率的动态响应速度较快，稳态补偿精度基本能够达到工程中无功补偿的要求。

The result showed that the carrier concentration of IMO was less than one third of that of ITO.So,the absorptance of visible light in IMO is lower than in ITO,there might br more space to improve the conductivity of IMO.

因此，IMO薄膜对可见光的吸收小，有很大的发展空间可以通过提高载流子浓度而进一步提高电导率，对近红外线也有较高的透射率，有利于拓展透明导电薄膜的应用领域。

To evaluate bone mineral density of normal humans in Henan of China,BMD of whole body,lumbar vertebrae,upper and lower limbs and pelvis of 417 healthy subjects was measured by Hologic 4500W dual energy X-ray absorptiometer made in USA.Only BMD of limbs and pelvis was analyzed.

为了解我国河南地区正常人骨密度的数据，作者应用美国Hologic生产的双能X线4500W型骨密度仪，对417例正常人进行了全身和腰椎正、侧位检测，现就四肢和骨盆骨密度的测试结果加以分析。

Excitations from localized states to the conduction band account for the absorption edge shift toward lower energies observed in the case of N/TiO_2 with respect to pure TiO_2.Mixture of visible light absorption of nitrogen doping and oxygen defect gave no obvious onset in the whole range between 400 and 800nm were observed of the samples N/TiO_(2-)A and N/TiO_(2-)M.

UV-VIS-DRS分析掺杂N/TiO_2结果表明，N/TiO_2-H和N/TiO_2-T两种催化剂在490nm处有吸收带边，可见光激发途径是掺杂的N以填隙方式形成的杂质能级吸收电子发生的跃迁引起的；而N/TiO_2-A和N/TiO_2-M两种方法得到的N/TiO_2在整个可见光区域内具有可见光吸收，没有显著的可见光吸收带边，其对可见光的激发途径是掺杂N和氧空缺共同作用的结果。

King-used washing machines Lower absorption law, the use of detergent added to the aqueous solution is in use at the same time fume emission will usually automatically with the aqueous solution of emulsifying oil mist and saponification reaction also been placed material washing down fuel from combustion of hazardous substances and cooking process generated fumes from aqueous solution by the majority and purification.

水帘式净油烟机采用洗涤吸收法，利用添加有洗涤剂的水溶液，在吸排油烟的同时自动将雾化的水溶液与油雾发生乳化和皂化反应，烟尘也同时被润湿洗涤下来，燃料燃烧时产生的有害物质及烹饪过程中产生的油烟绝大部分被水溶液中和净化。
