垃圾浸出液厌氧处理研究

本研究采用厌氧—好氧生物氧化的工艺技术,自行设计和制造了一套有机玻璃为材料的模拟装置,对垃圾浸出液进行处理研究。经试验结果表明,利用本设计装置处理后的污水,可运到国家农田灌溉的污水排放指标并基本达到国家三类废水的排放指标。该成果已通过市级专家鉴定,并将应用于垃圾场淤出污水的处理工程。     

中国梅的变异与分布研究

通过文献阅读、标本查阅及实地考察，发现了梅的一些变异类型。提出了梅的地理分布格局，对梅分布的历史迁作的探讨。种、滇、藏交界的横断山区是梅的自然分布中心，另外还有一些亚中心；在对种群数量和变异类型研究的基础上，确认梅的自然分布中心即梅的变异中心。     

二阶拟线性椭圓型Euler方程组解的Pohozaev型恒等式及其应用

本文对于二阶椭圆型Euler方程组 -∑D_αF_(q_α~i)(x,u,Du)+F_(ui)(x,u,Du)=0得到了一些积分恒等式,利用这些恒等式证明了某些方程组非平凡解的不存在性。     

改进芳草A系原种产卵性的试验

本试验采取母蛾延迟交配，拆对后冷藏、改变交配时间和产卵室保护温度等技术措施来探讨改善芳草A系原种产卵性的方法。结果表明，这些措施对产卵性能的改进有一定的效应，但由于性状间存在相关关系，对某一性状的促进效应往往同时也对另一产卵性状产生负向影响。     

Expression and modulation of connective tissue growth factor in renal interstitial fibrosis

CTGF, a member of the CCN family of immediate early genes, is a recently discovered profibrotic growth factor, which is involved in many pathophysiologic procedures. CTGF acts as a downstream effector of TGF-β acting on interstitial cells to enhance the progression of fibrotic renal diseases. It has been shown that CTGF gene expression can be induced or blocked by some kinds of cytokine and drugs. It is an interesting candidate target for future intervention strategies of renal interstitial fibrosis.

Effect of Nitrogen Rate and Stubble Height on Dry Matter Yield,Crude Protein Content and Crude Protein Yield of a Sorghum–Sudangrass Hybrid[Sorghum bicolor (L.) Moench × Sorghum sudanense (Piper) Stapf.] in the Three‐Cutting System

In this study, the effects of nitrogen (N) rate (60, 120, 180 and 240 kg N ha^?1 applied in three equal dressings at seeding and after the first and second cuttings) and stubble height (7, 14 and 21 cm) on the dry matter (DM) yield, crude protein (CP) content, and CP yield of a sorghum–sudangrass hybrid [Sorghum bicolor (L.) Moench × Sorghum sudanense (Piper) Stapf., cv. Pioneer 988] in the three‐cut system was investigated. The N rate had no significant effect in the first and third cuttings, but in the second cutting DM yields increased significantly with increase in N rate. The highest yield of 9.1 t ha^?1 was obtained with 80 kg N ha^?1 for the average of 2 years at the second cutting, but no significant difference was found among the 40, 60 and 80 kg N ha^?1 rates. CP content and yield were not significantly affected by N rate at the first and third cuttings, but CP content and yield were significantly affected by application of N at the second cutting. Stubble height had a significant effect on CP content at the third cutting. However, it had no significant effect on CP content at the first and second cuttings. Stubble height had a significant effect on the CP yield at the first cutting, but no significant effect on CP yield at the second and third cuttings.

表达HAV结构基因的重组腺病毒鉴定及细胞病变分析

利用RT-PCR方法,从HAV-L8株的RNA中扩增出结构基因(vp3 vp1),克隆到穿梭质粒pXCX2NotI上。采用磷酸钙-DNA共沉淀技术,将腺病毒载体pJM17与pXCX2-CMV-HAV共转染293细胞。在光学显微镜下观察到明显的细胞病变(CPE);经RT-PCR、免疫荧光染色和蛋白印迹鉴定证明HAV的结构基因已插入到腺病毒基因组中;在电子显微镜下观察发现有二十面体的病毒颗粒。以上结果表明获得了重组腺病毒rAdHAV,纯化后的rAdHAV滴度为1×109.0TCID50/mL。
