To evaluate the efficacy of the recombinant fowlpox virus vaccine against the heterotype IBV, the chickens were challenged with the homotype IBV LX4 strain and the heterotype IBV LTJ95I strain after three weeks post vaccination. Antibodies against IBV were detected in vaccinated chickens one week post inoculation. The CD4+ T-lymphocytes in the peripheral blood increased rapidly in all groups challenged with IBV, except for the vaccinated group challenged by heterotype strain and the low level of CD4+ T-lymphocytes remained until end of the experiment. In all the groups, a high level of CD8+ T-lymphocytes only was observed in the vaccinated group after challenging with IBVhomotype strain. The morbidity and the mortality of this group were 21.43 % and 0 %, respectively, which showed significant difference with other groups. In addition, the lesions of chickens and virus shedding were less in the vaccinated group challenged by IBV homotype strain comparing with other groups, but there was no difference for the average body weight of chickens in all groups.

结果显示，重组疫苗接种1周后，免疫鸡产生抗IBV的抗体；而且外周血中CD4+和CD8+ T淋巴细胞的含量略高于非免疫对照组；攻毒后，异源强毒株攻毒的免疫组CD4+ T淋巴细胞呈下降趋势，并且该组低水平CD4+的状态一直持续到试验结束，而其他组CD4+ T淋巴细胞均迅速上升，峰值达到14.5 %；同源强毒株攻毒的免疫组CD8+ T淋巴细胞呈高水平的表达，而其他组攻毒后均无明显变化；保护率结果显示，同源强毒株攻毒免疫组的发病率和死亡率为21.43 %和0 %，与其他各组相比均有显著差异；另外同源强毒株攻毒的免疫组病理损伤与异源强毒株攻毒的试验组相比明显减轻，其排毒时间和排毒量也均有所减少；强毒攻毒后所有试验组体重无显著差异。

Band differencing is feasible in water and irrigable field, but it couldnt monitor the changes of whole land use and its precision is the lowest. For the mufti-temporal composite method, it is difficult to choose the exact regions for change detection. Based on the previous accurate classification result, the post classification comparison method gets the best result compared with the other two methods, but also with the hand-on mistakes.

图像差值法对河流水面和水浇地的监测效果比较好，但对所有地类监测结果不令人满意，精度较低；多时相波段复合分类法中，变化土地类型训练区的确定较困难；分类后比较法是在前面土地信息准确提取的基础上进行的分析，精度较高，监测结果图也一目了然，是土地利用动态监测的一种有效方法，但它是在自动识别分类基础上进行的比较，传递了分类产生的误差。

The results indicate the effect of light level, visual angle and eccentricity on detection rate and reaction time at mesopic region; shows series of spectral luminous efficacy drawn out from the experimental results since monochromatic stimulus was used; proves that the results from performance-based method are in essence compatible with those from bright-matching method, since both of them are in accordance

本论文实验和计算结果确定了背景亮度、视场角和偏心度对人眼探测率和反应时间的影响程度；根据视觉功能的基础和实验中选用单色光谱作为视觉目标所得到的数据推导出人眼在中间视觉状态下的系列的光谱光视效率函数；本文研究结果证实了基于视觉功能法和视亮度匹配法所获得的光谱光视效率函数在本质上的一致性，它们都能反映出随着亮度降低而产生的浦尔金耶偏移效应(Purkinje-shift)，但本论文所采用的基于视觉功能法还能反映出人眼视觉信息处理中的颜色通道效应。

Secondly,UV spectrophotometry was adopted to research the combination action on SM_2 and SIZ with MAA and 4-Vp.The combination action of functional monomer with template molecules were produced in the results. Then,the prediction imprinting principle of SM_2 and SIZ were given. The diagrams of infrared spectrum were analysed in MAA and 4-Vp and IMPs of SM_2. It was discoved that the absorbability peak of C=C function group in the IMPs were turn to be very low ,but the function group of carboxylic acid and pyridyl in the IMPs were no evidence change, and the condition was created in the molecular recognition of MIPs. Thermal Analysis was adopted to research IMPs ,in which ,a better thermal stability and its decompose temperature were showed in the results.

Results The results showed that the optimum carban and nitrogen resource were sucrose and lopassium niruate. The growth rates of mycelia were fastest at the temperature of 30 ℃ and pH value 6. Darkness was benefitial to hyphal growth, but light was benefitial to sclerotial formation.

The results are in good agreement with available experimental results. The entropy effect on the Gibbs free energies of 6-thioxanthine base is very small and there is little significance for the tautomeric equilibria of the base.

计算结果同已有实验结果一致。6-硫代黄嘌呤异构化的熵效应小，对互变异构平衡几乎没有显著的影响，而焓变对互变异构产生了主要的影响。

In the case of granite, observation results indicate that the extending routes of active cracks are mainly intercrystalline, transcrystalline, inter-transcrystalline, and intracrystalline. When the strain rate is low, the long intercrystalline cracks are prevailing, and with increasing of the strain rate, the short transcrystalline and intracrystalline cracks gradually increase. The statistic results show that the active crack density increases with increasing of the strain rate, and the mean length of active cracks diminishes with increasing of the strain rate, that is, the induced damage in comminuted product increases with increasing of the strain rate. For the first time this dissertation integrates macroscopic results of comminution with active crack growth under impact loading. It elucidates why the dynamic comminution strength of mineral beds increases with increasing of the strain rate through the active crack extending, and analyzes the influence of structure and constitution of minerals on their damage under impact stress. It is authenticated that both the size distribution and the damage population of comminuted product can be characterized by the fractal.

为分析料层颗粒在冲击下的细观损伤效果，采用德国生产的ASM68K半自动图象分析仪对粉碎生成物中的损伤情形进行了观测，以花岗岩为例，观测结果表明花岗岩颗粒在冲击应力下的活化裂纹扩展路径主要表现为沿晶、穿晶、沿穿晶和晶内等形式，在低应变速率下，活化裂纹以沿晶裂纹较多，随着应变速率的提高，其它裂纹形式大量繁衍，统计结果表明活化裂纹密度随着应变速率的增大而增大，活化裂纹的平均长度随着应变速率的增大而减小，综合表现为颗粒的细观损伤程度随着应变速率的增大而增大；首次将应力作用下的活化裂纹演化特征与粉碎的宏观效果相联系，并就料层动态粉碎强度随应变速率增大而提高的现象从裂纹演化特征的角度进行了解释；分析了矿岩构造结构特性对损伤产生和分布的影响。
