The half-life day of HCH, DDT and chlorpyrifos was 27~32, 27~33 and 22~24 respectively and the residue were detected in the substrates and fruitbodies when fungi were inoculated to the substrated, There were no cypermethrin detected in the fruitbodies, and it's half-life day in the substrate was 19~20. Carbendazim used for control germina was also detected in the substrates and fruitbodies with a half-life from 19 days to 20 days. Because of it's short half-life (2 days to 4 days), the degradation of Chlorothalonil in substrates and fruitbodie were quickly and no chlorothanonil were detected both in the substrates and fruitbodies when harves.

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 comparisons of biochemistry between OP and OR rats The differences between OP and OR rats included not only body weight, but lipids metabolism and insulin sensitivity as well, characterized with insulin resistance, increasing in serum free fatty acids and ketone body, and hepatic TC and TG in OP rats. However, no significant differences were observed in serum TG, TC, LDL, HDL and fasting glucose between OP and OR rats.⑶Comparisons of metabolites in serum, urine and liver tissue between OP and OR rats①There were significant differences in amino acids concentration between OP and OR rats,especially in liver tissue, such as high concentrations in ketogenic and glucogenic amino acids in OP rats, suggesting differences in amino acids metabolism;② The different metabolites between OP and OR rats included increasing of various saturated fatty acids and decreasing of polyunsaturated fatty acids in OP rats;③The urinary metabolites analysis indicated that different structure or metabolism of gut microflora might exist between the two phenotypes, which probably influenced the regulation of body weight gain;④The end-products of catecholamines in urine and intermediates of krebs cycle in serum in OP rats were all up-regulated, suggesting that the activity of sympatheic nervous system and energy metabolism was higher in OP rats than OR rats.

The contents of N, P, K in leaves were examined by regular leaf analysis. The results showed that the N content was higher in leaf blade than in leafstalk. N content in leaf was gradually reduced along with the vine growth. N, F, K fertilized at 20 to 40 cm soil layers significantly increased N content in leaf. But N content in leafstalk was less affected by N fertilization depth and growing season. P content was higher in leafstalk than in leaf blade. Less change of P content was noticed in leaf along with vine growth. However, N, P, K fertilized at 40 to 60 cm soil layers significantly promoted P in both leaf blade and leafstalk. K content in leafstalk was much higher than in leaf Wade. No obvious influence was noticed by fertilizing depth. But K content in leafstalk was significantly increased due to applied K fertilizer in late growing season.

通过理论分析和实验研究,本文得出以下结论:高承压水在沿煤层底板隔水层导升过程中存在着明显的压力水头损失;同一地层条件下,煤层底板承压水水头压力越大其导升过程中的水头压力损耗就越大;同一水头压力条件下,地层的渗透性越差其阻水能力越强,水流导升过程中的水头压力损耗也越大;在同一介质中,当初始水头压力不同时,水流在导升过程中水头压力的衰减不同,在同一隔水介质中底板含水层水头压力越大其沿隔水层导升过程中的水头损耗也就越大,水头损耗随底板隔水层水头压力增加而呈递增趋势,另外它们相应的水头衰减速率也呈递增趋势,煤层底板隔
