o3造句

• The total ozone distribution over stratosphere layer in china appears obviously seasonal variation tendency, that is, the value of total ozone in spring and winter is higher than that in summer and autumn, while the maximum of surface o3 over waliguan is in summer, which is relatively late, approximately 2-3 months, it illustrates that the vertical transport from stratosphere has important effect to the increasing of surface o3 . compare to the izana global observatory, surface o3 has been slowly increasing, but not so stable, it also shows that the monitoring of surface o3 has global scale, and its data has comparability in the world
  (7)中国大陆上空平流层臭氧柱总量分布存在明显的季节变化趋势，即冬春季臭氧柱总量高于夏秋季；瓦里关近地面层臭氧浓度最高值出现在夏季，落后平流层23个月，说明在瓦里关地区夏季平流层o_3的垂直输送对地面臭氧浓度的增加发挥着重要作用；(9)与izana全球站相比，地面o_3均呈逐年上升趋势，上升较为缓慢，且不太稳定，说明瓦里关地区地面o_3监测具有一定的全球尺度和国际可比性。

• Moreover, the quenching concentration of eu is raised . on the basement of successful synthesis of two-components oxide, edta complexing sol-gel method was expanded and applied to effectively synthesis nanosized muti-components oxide, such as la1-xsrx fe o3, lafe1-xcuxo3, la1-xsrx coo3, laco1-xcuxo3 because edta can bind with most metallic elements of the periodic table, this technique become a versatile tool in the production and study of new nano materials of multi-component complex oxides . a economic and new process has been studied to synthesis la2o3 nanocrystalline, using nh4hco3 as precipitant
  河北大学理学博士学位论文对于单一组份的稀土氧化物，探索出一条更经济、更方便的合成方法，即:用碳酸氢钱做稀土沉淀剂，成功地制备了纳米l匆03，并对中间产物碳酸斓及其烧成的氧化斓分别进行了ir、tg一dta、sem、xrd分析研究，确定了碳酸悯的组成，氧化斓的物相、结构，并发现分散剂的种类对微观形貌有一定的影响。
• The long distance transport of pollutant from the direction of se, ene and etc, has some influences to the variation of surface o3 over waliguan, due to the short life of precursors, and the long distance between two sites as well as the weak photochemical reaction over this area, the influence of wind direction is not so important
  (7)在se、ene等东北方向上污染物(no_x等)的长距离水平输送对瓦里关地面o_3具有一定的影响。但由于o_3前提物在大气中的寿命较短，两地又相距较远，而且瓦里关地区光化学反应很弱。因此，水平风向对地面o_3影响不大。
• The influence that the zr / ti ratios have on the ceramic crystal structure and its properties are studied through the research carried out about the relative respects of the fabricated samples . the increase of zr / ti ratio can result in the crystal structure transformation from the tetragonal to the rhombohedral, it can also induce the weakness in the stability of the ceramic crystal structure, for example, the drop in the curie temperature . in order to enhance the relative low mechanical quality factor of pzn-pzt system piezoceramics, component addition pb ( mn1 / 3sb2 / 3 ) o3 ( hereafter abbreviated as pms ) are introduced in to form a new psudo-tetragonal system ceramics
  为获得具有高的机电耦合系数kp，高的机械品质因数qm的高性能压电陶瓷，采用二次合成法制备了不同zrti比的铌锌酸铅-锆钛酸铅基(pzn-pzt)三元系压电陶瓷材料，研究了zrti比变化对陶瓷结构和性能的影响规律，发现zrti比增大除了可以使陶瓷的相结构由四方相向三方相转化外，还降低了陶瓷的结构的稳定性，使tc温度下降。
• Besides the ordinary treatment techniques, the safe drinking water treatment system on a pilot scale also consists of several new techniques such as o3 contacted oxidation / o3 catalytic oxidation, nanofiltration and reverse osmosis filtration, dynamic membrane resin adsorption, photochemical catalytic oxidation and pipe network biomembrane control techniques
