By getting Lebesgue characteristic of integrable function of Riemann from the definition of Gather zero measure, discussing the relation between almost continuous everywhere and existent of limit, it gets the theory which is from the function integrability to the consecution and from consecution to the limit existence .i.e. the almost limit existence is equal to the almost continuous everywhere in the integrable function of Riemann. It also gets a unified condition which has a wider range than regulated function and comes to the conclusion that the function of bounded variation is the integrable function of Riemann.

In this dissertation, we optimized the thinkness of each layer of TFEL devices using the layered optimization method to obtain ZnS: Ce〓 TFEL devices. Accoding to the energy level structure of Ce〓, two criteria for distinguishing the EL of Ce〓 were found out, from which it was conduded that the TFEL of ZnS: Ce〓 comes from 5d→4f transition of Ce〓. The measurement of brightness waveform showed that the TFEL of ZnS: Ce〓 was the luminescence from independent centers. and there were the field induced-delocalization in this process anf it〓s the cause of low TFEL efficiency of ZnS: Ce〓. In this dissertation, different influence factors on TFEL of ZnS: Ce〓 were sdudied. The influence of different host lattice is different: The blue/green ratio of ZnS: Ce〓 in hexagonal system of ZnS is larger than that in cubic system of ZnS, and the TFEL peaks in hexagonal system of ZnS moves toward longer wavelength compared with that in cubic system of ZnS. The adding buffer layer was used in this stage. The solubility of Ce〓 in ZnS was small and it was another limit to TFEL brightness of ZnS: Ce〓 device. The solubility of Ce〓 increased ten times when using Li ions as flux, so that the TFEL brightness of ZnS: Ce〓 was enhanced. It was found that the appearing of ZnO in active layer improves the TFEL of ZnS: Ce〓: the brightness and the wave range of ZnS: Ce〓TFEL were enhanced.

本文采用TFEL的分层优化方案，优化组合了各膜层厚度，选择最佳制备条件，得到了ZnS：Ce〓的TFEL；根据Ce〓的能级结构，找到了判别Ce〓的EL的两个简单依据，并据此断定ZnS：Ce〓的TFEL的两个发射峰分别属于Ce〓的〓和〓跃迁；亮度波形测量表明ZnS：Ce〓的TFEL属于分立中心发光，分析认为在此过程中存在着较严重的场致离化，这也是ZnS：Ce〓的TFEL效率较低的一个原因；本文考查了影响ZnS：Ce〓的TFEL的各种因素，发现：基质的晶体结构对ZnS：Ce〓的TFEL有所影响，在六角相ZnS中Ce〓的TFEL优于立方相ZnS中Ce〓的TFEL：发射峰的蓝-绿比相对较大，且光谱向短波方向移动，在此项研究中本文采用了在发光层前增镀过渡层的办法，过渡层为六角晶相的ZnO；限制ZnS：Ce〓的TFEL器件亮度的一个原因是Ce〓在ZnS中的溶解度低，本文用Li离子作助溶剂增大了Ce〓的溶解度，增大幅度为一个量级，并且ZnS：Ce〓的TFEL亮度明显提高；从ZnS：Ce〓的TFEL光谱来看ZnS：Ce〓的TFEL波长覆盖范围较小，亮度也不高，达不到做为白色TFEL材料的要求，需要寻找新的白色TFEL材料；在研究ZnS：Ce〓的TFEL中还发现：发光层中ZnO的出现有利于ZnS：Ce〓的TFEL：发射峰变宽、亮度增大。

The Chinese television profession from it that moment which is born in China, experienced take propagandized the attribute as the leading first stage, take creator art work attribute as leading second stage, Enters slowly has occupied the dominant position now by the cultural commodity the third stage, after at present this stage field weight standard is each column weighting the viewing ratio height, But regardless of has various understanding and the discussion to the viewing ratio, also no matter the viewing ratio essence is good or bad, the list from the data analysis starting point, it indeed can reflect and explain very many questions, In view of the fact that the author at the Central Committee Television seventh set of agriculture program " the date of the countryside " the column practical work experience with CCTV Rope Luck Switzerland Investigation Company the data feedback which column each reception of TV investigates to "the date of the countryside", Simultaneously furthermore has to the agricultural dissemination study concrete understanding, this article analyzes emphatically from the television jobholders' angle to this range pole -like viewing ratio data, obtains corresponding fords the agricultural television conversation class program the creation method and to the television medium thorough understanding.

中国电视行业从其在中国诞生的那一刻起，经历了以宣传属性为主导的第一阶段，以创作者艺术作品属性为主导的第二阶段，慢慢进入了现在以文化商品占主导地位的第三阶段，目前这个阶段业界的衡量标准就是各频道各栏目加权后收视率的高低，但是无论对收视率有何种理解和探讨，也不管收视率的本质是好还是坏，单从数据分析的出发点来说，它的确能够反映和说明很多问题，鉴于笔者在中央电视台第七套农业节目《乡约》栏目的实际工作经验和央视索福瑞调查公司对《乡约》栏目各项收视调查的数据反馈，同时更兼有对农业传播学的具体理解，本文着重从电视从业人员的角度对这个标杆式的收视率数据加以分析，得出相应的涉农电视谈话类节目的创作方法和对电视媒介走向的理解。因此本文是建立在对《乡约》栏目的收视率数据分析、受众收视倾向分析以及《乡约》栏目的电视节目创作经验总结基础上所得出的涉农类电视访谈节目的创作规律和理念。
