Electrochemical assembly of [Ru（bpy）2dppz]^2＋{bpy=2,2＇-bipyridine, dppz=dipyrido[3,2-a：＂2＇,3＇-c]phenazine} on an ITO electrode in the presence of guanine and photoelectroehemical properties of the assembled layer were investigated. It has been found that [Ru（bpy）2dppz]^3＋/2＋ can be assembled onto the ITO electrode by the method of repetitive voltammetric sweeping, and the assembly is enhanced by guanine. The peak currents of prewaves increase linearly up to a guanine concentration of 0.25 mmol/L. More importantly, upon illumination with 470 nm light source and at an applied potential of 0.2 V, cathodic current for the fabricated layer on the ITO electrode indicate a linear enhancement with the rise of guanine concentration. Meanwhile, [Ru（bpy）2dppz]^2＋ can be served as an excellent mediator to prompt the oxidation of guanine, and the mediated peak current increases linearly with added guanine concentration from 0.01 to 0.25 mmol/L. In addition, the assembly mechanism of [Ru（bpy）2dppz]^2＋ on the ITO electrode associated with the oxidation of guanine and the assistance of light irradiation were discussed.

Agricultural Sciences in China 2002年第8期1卷 905-910页

作者： SONG guo-qing, yu Ke-shun, LI Shao-hua, LIU guo-jie, MENG Zhao-qing and ZHU Jun(Department of Fruit Science, China Agricultural University, Beijing 100094 , P.R.China) Department of Fruit Science China Agricultural University Beijing 100094 P.R. China

The fruit growth evolution on 35 tagged 'Fuji' apple trees was studied in three successive growing seasons from 1994 to 1996 to explore a new method for forecasting the fruit diameter at harvest during early growing season. Daily fruit growth rate (DFGR) (based on fruit diameter, fruit dry weight, fruit fresh weight, or fruit volume) during the early growing season, 30 - 50 d after full bloom (DAFB), or during mid-growing season (60-120 DAFB), displayed a strong positive linear correlation with the fruit diameter at harvest, and the correlation between the fruit diameter at harvest and DFGR during early and mid-growing season was much better than that between the fruit diameter at harvest and either fruit diameter at a given time or the relative growth rate during early or mid-growing season. The fruit diameters obtained in the field were compared with the mean fruit diameters estimated based on different criteria, such as DFGRs (based on fruit diameter, fruit dry weight, fruit fresh weight, or fruit volume) during early and mid-growing season, and fruit diameter at 120 DAFB. Results showed that daily growth rate of fruit diameter during 30 - 50 DAFB was the best criterion for forecasting fruit diameter at harvest. There was no significant difference in mean fruit diameter between the value measured in the field at harvest and that estimated based on the daily growth rate of fruit diameter during 30 - 50 DAFB (equations for forecasting: y = 153.571 x + 73.492) either for the individual trees or for different vigor groups of trees. Daily growth rate of fruit diameter during 30 - 50 DAFB can be used as the basis for forecasting fruit diameter at harvest.

该文提出了一种基于三折线结构抗力形式和升压平台形荷载函数的非线性单自由度模型,并推导了该模型的解析解,用于分析由单柱移除引起的连续倒塌过程中的结构瞬态动力响应。该模型可以涵盖各类抗力形式,包括抗力软化及大变形条件下的悬链作用,并考虑了柱子移除时间对动力响应的影响。钢筋混凝土和钢结构的梁柱子结构的动力试验结果与非线性单自由度模型计算所得到的动力响应结果(例如跨中位移)的对比表明:此模型可以准确地预测结构倒塌过程中结构的动力响应,计算速度快,准确性高,便于应用。

2004年冬季在集美凤林类似底质类型、盐度和潮位的海湾地段4个断面，就不同红树植物林中的小型底栖动物数量和自由生活海洋线虫群落进行了研究。结果表明：海洋线虫是凤林红树林中小型底栖动物中的绝对优势类群，占到小型底栖动物的76．1％～96．3％；从丰度来看，旧区白骨壤（Avicennia marina）林中小型底栖动物的数量较少，有污水流过的光滩数量较大；4个断面共鉴定出海洋线虫37种（分类实体单元），其中新区秋茄（Kandelia candel）林中的生物多样性指数较低，旧区白骨壤林中群落具有较高的物种多样性；从出现的物种来看，新区秋茄林、旧区白骨壤林和光滩上出现的优势种和摄食功能群的类型各不相同。从4个断面13个站位进行的聚类分析和MDS标序分析结果推断自由生活海洋线虫的群落结构与不同的红树植物形成的沉积物有关。

经济周期是经济增长过程中不可避免的现象。为尽可能避免经济运行出现过度波动,财政政策成为各国政府调控经济运行的常用工具。通过用HP滤波方法剔除掉中国产出、财政收入、财政支出和财政赤字中的趋势成分后,用产出缺口、财政收入缺口、财政支出缺口和财政赤字缺口进行计量分析,发现中国财政周期性波动中的财政赤字波动对宏观经济产生了明显的稳定效应,并且随着市场经济的逐步完善,政府调控经济运行的能力也在逐步增强。

Unlike other non-gynecologic solid tumors, such as breast cancer, lung cancer, metastasis to bone from endometrial carcinoma is rare, metastasis to extremity is extremely rare. We report a 51-year-old multiparous woman with FIGO Stage IVb Grade 2 endometrial adenocarcinoma which metastasized to left lower extremity bone. She received an amputation of left lower extremity below the knees, and a total abdominal hysterectomy and bilateral salpingo-oophorectomy, and followed by systemic chemotherapy, radiation therapy to the pelvis and progestational agent. She had a complete response to above treatments, and disease-free survival for 10 months. After recurrence, she received chemotherapy, radiotherapy and progestational agent once again. She had lived 56 months and is still alive by the time of report. Metastasis of endometrial carcinoma to extremity bone can rarely occur and should be considered when the patient with endometrial carcinoma complained of unexplained pain and swelling associated with extremity bone.

财政投入最优规模是经济学界研究的重要问题,国内外很多文献都有相关论证,并且得出了不同结论。通过构建符合我国具体情况的农业生产函数模型,并代入我国1981—2004年的财政支出与经济增长相关数据进行回归,发现中国财政农业投入最优规模为8.26%,实际投入规模要小于此最优水平。因此未来应进一步加大财政对农业的支持力度,确保农业经济的长期稳定健康增长。
