The pore capacity is becoming smaller with increasingthe vitrinite content. 2. Micro-porosity is dominated in the total pore capacity, which takes more than50%. There is not relationship among pore capacity and specific surface with otherfactors such as Maceral and R0, which shows that the distribution and shapes of poreare not influenced by the composition of the coal. 3. The pore is opened for the coal of Ordos Basin, the order is from durain to clarainthen samples to vitrain. Others are belong to half-opened and thin throat. 4. The adsorption content of gas is increasing with the higher pressure, and the freegas content is decreasing;The adsorption content of gas is decreasing with thehigher temp, and the free gas content is increasing;The adsorption content of gas isincreasing with higher vitrinite content for the kennel coal when temp.
总空隙主要由小孔孔容构成,小孔孔容占了50%以上;镜质组含量和惰性组含量等物质以及镜煤反射率均与孔容、比表面未表现出明显的相关性,说明孔隙分布特征不受物质组成的影响 3、鄂尔多斯地区的空隙呈现开放状态为主,空隙开放的次序为暗煤-亮煤-煤样-镜煤,其他盆地则为半封闭和细瓶颈空隙 4、随压力增加,煤对气体的吸附量增加,煤中所含游离气的量随之减小;随温度增加,煤对气体的吸附量减小,而煤中所含游离气的量随之增加;在相同的温压条件下,同是长焰煤的样品,吸附量在孔容中所占的比例随镜质组含量增加而增加。

The empirical result demonstrates that:(1) the average abnormal reture and accumulated average abnormal reture around and after quarter surplus announcement change obviously, which illustrates the quarter surplus reports are of information content in our A share market;(2) the market can treat different types of accounting surplus data distinguishly by analysing inexpectant surplus as good news or bad news, but it reacts intensely to good news and flatly to bad news:(3) the market investors are paying more and more attention on accounting surplus of listed companies, which can be viewed in the annual text that the surplus reaction coefficient significance enhances;(4) A share market is, basically, under a state of semi-strong efficiency, or at least of an effective process from weak to semi-strong.
实证结果表明:(1)季度盈余报告公布前后平均非正常收益率和累积平均非正常收益率都发生了明显的变化,说明在我国A股市场季度盈余报告是具有信息含量的;(2)通过对未预期盈余分为利好组和利空组的分析,得出市场能够区别对待不同性质的会计盈余数据,但是市场对利空消息反应强烈,对利好消息反应平淡;(3)在分年度的检验中,可以看到盈余反应系数的显著性不断增强,证明我国A股市场的投资者对于上市公司会计盈余的重视程度在不断增加;(4)研究结果倾向于我国A股市场基本处于半强式效率,至少我国证券市场正处在从弱式有效向半强式有效转变的过程中。

Through the comparative analysis of the arthropod community between intercropping system and the three control systems~the weeding jujube yard system, not weeding jujube yard system and the system of farmland, it is showed that the intercropping system have a more richer neutral arthropod groups. Compared to Weeding jujube yard system and system of farmland the intercropping system have more advantages in natural enemies groups and more disadvantaged phytophagy groups. And the intercropping system can rebuild the arthropod community more faster than the other systems after the system was seriously disturbed, so it is than compared to other three systems the intercropping system have more proper structure and more stronger regulation ability and also more stronger ability to control pest.
对枣粮间作系统和三种对照系统,即除草枣园系统、未除草枣园系统和农田系统的节肢动物群落进行对比分析发现枣粮间作系统具有更为丰富的中性节肢动物类群,比起除草枣园系统和农田系统有更优势的天敌类群和更劣势的植食性类群,且在遭受生境的巨大变化后新生境重新形成时枣粮间作系统的各亚系统能更迅速的形成节肢动物群落和各种功能类群,说明枣粮间作系统比三种对照系统的节肢动物群落有着更合理的结构、更强的调控能力和更强的控害能力。

Based on the laser longitudinal mode splitting theory, a novel scheme of dual-frequency laser with large frequency-difference is presented using electrically controlled birefringence of liquid crystal, and the transmitted resonant mode splitting by birefringent of Fabry-Perot etalon has been analyzed theoretically. A new element of liquid crystal Fabry-Perot etalon is designed and fabricated, which serves as aselector and splitter of both laser longitudinal modes and Fabry-Perot etalons transmitted resonant modes. Two different experimental systems of laser-diode end-pumped Nd:YAG laser have been set up using two different LDs, and the transmission of liquid-crystal cell have been measured. When the empty LCFP is inserted in the cavity of high-power LD pumped Nd:YAG laser, the oscillation of a single laser longitudinal mode have been observed, such a result shows that the designed and fabricated LCFP element is capable of selecting single axial mode. While an anti-reflected liquid crystal cell is inserted in the cavity of Nd:YAG laser end-pumped by the high-power LD, it is difficult to confirm weather the laser longitudinal modes have been spitted or not. The subject is summarized in this thesis and the improvement of the project has been presented.
论文以激光纵模的分裂理论为基础,提出了可望获得几十GHz甚至上百GHz的液晶电控双折射双频Nd:YAG激光器的总体方案,并对用双折射效应分裂F-P标准具透射谐振模进行了理论分析;设计并加工了一种集激光纵模选择、激光纵模分裂和F-P标准具谐振透射模分裂于一体的多功能元件——液晶电控双折射F-P标准具;建立了两种不同功率激光二极管端面泵浦的Nd:YAG激光实验系统,并对液晶盒的透射性质进行了测试;将未灌注液晶的空液晶F-P摘要标准具插入大功率LD泵浦Nd:、叭G激光谐振腔内,观察到了单纵模激光输出,说明所设计和加工的液晶F一P标准具具有纵模选择能力;将镀有增透膜的液晶盒插入大功率LD泵浦Nd八7AG激光谐振腔内,是否产生了激光纵模分裂现象还难以确定。

Chapter three is the degradation of Abamectin in soils. The results show:(1) The decomposition of Abamectin is fastest in Aquic Cambosols while slowest in Udic Cambosols in five kinds of different soils.(2) Organic matter content in soil is the most important factor which influences the degradation half-life of Abamectin in soil, and their relative coefficient arrives at 0.9323, but pH value, total nitrogen, CEC and field maximum moisture capacity correlate little.(3) Soil organic matter, soil temperature and pesticide concentration can obviously affect Abamectin degradation in soil, in addition, the degradation half-life of Abamectin in sterilized soil is far more than that in non-sterilized soil, which maybe contributes to microorganism in soil. Chapter four is the microbial degradation of Abamectin.
第三章研究了阿维菌素在土壤中的降解,结果表明:(1)五种不同类型土壤中,阿维菌素在潮湿雏形土中降解最快,而在湿润雏形土中降解最慢;(2)土壤有机质含量与阿维菌素半衰期相关性较强,相关系数为0.9323,而土壤酸碱度、总氮含量、阳离子交换量和田间最大持水量等因子与阿维菌素半衰期相关性较小,说明影响阿维菌素在土壤中降解的最主要因子为有机质含量;(3)土壤有机质、土壤温度和农药浓度等因素对阿维菌素在土壤中的降解有较大影响,此外灭菌条件下其降解半衰期远大于未灭菌时的半衰期,这表明阿维菌素在土壤中的降解可能和土壤微生物有关。

Many waves are there agitated by the wind, keeping nature fresh, the spray blowing in your face, reeds and rushes waving; ducks by the hundred, all uneasy in the surf, in the raw wind, just ready to rise, and now going off with a clatter and a whistling like riggers straight for Labrador, flying against the stiff gale with reefed wings, or else circling round first, with all their paddles briskly moving, just over the surf, to reconnoitre you before they leave these parts; gulls wheeling overhead, muskrats swimming for dear life, wet and cold, with no fire to warm them by that you know of; their labored homes rising here and there like haystacks; and countless mice and moles and winged titmice along the sunny windy shore; cranberries tossed on the waves and heaving up on the beach, their little red skiffs beating about among the alders;-- such healthy natural tumult as proves the last day is not yet at hand.
那儿风大,空气清新,激流拍岸,水花四溅直朝你脸上扑来,芦苇草和灯心草迎风翻舞。成群的鸭子在巨浪狂风中不安地游向岸边,正要上岸时,随着一阵嘎嘎的叫声,纷纷散去,直奔往Labrador,有的瑟缩着翅膀逆风飞行,有的先是浮在浪头打转,快速地扑打着双蹼,打量了一眼船上的人才离去;海鸥在空中盘旋,麝鼠也奋力游着,浑身湿冷,它们可不能和人一样用火取暖,到处是它们象草堆一样垄起的房子。晴朗多风的岸边,有数不清的老鼠,鼹鼠和山雀;酸果蔓在波浪中招摇,红色的小艇摇晃穿梭在桤木丛中-----这种生机勃勃的景象说明世界末日远未来临。
