| 2 | 秸秆在土壤内分解初期氮素矿化与固持的模拟测定显示文摘利用模拟软件Modelmaker对3种作物秸秆在土壤内分解初期氮素循环转化过程进行了模拟,取得了土壤铵态氮、硝态氮、微生物氮及其15N丰度等6个变量模拟值和测定值的良好一致性.模型模拟对氮转化速率测定的结果表明,土壤微生物主要固持铵态氮,对硝态氮固持非常微弱.氮矿化主要发生于作物秸秆,腐殖质氮的矿化极其微弱.一级动力学方程对秸秆氮素矿化过程的描述优于零级动力学方程.微生物固持氮的再矿化过程落后于氮固持过程,假定再矿化不发生或认为再矿化与固持化同时进行可导致氮矿化与固持速率测定的严重误差.忽略氮硝化过程和挥发损失将导致氮矿化和固持速率的测定值偏低.净固持或净矿化的产生不仅与秸秆碳氮比有关,而且与秸秆在土壤内分解时间有关. | 胡希远 Kuehne R.F. | 2005 | 应用生态学报2005,16,2: | 24 |

| 4 | PLASMA MODEL-ONE MODEL OF ELECTROMAGNETIC RESPONSE OF MATTER显示文摘The prerequisite and mode of electromagnetic response of nano metal/dielectric films to electromagnetic wave field were suggested. With the carrier density and the reflectance, transmittance of the film, the plasma frequency and the dependence of absorptance on the frequency of electromagnetic wave field were calculated respectively. The calculated results accorded with the experimental ones, which proved the plasma resonance is one mode of electromagnetic response. | H. Du, J. Gong, C. Sun, A.L. Ji, R.F. Huang and L.S.

| 6 | 儿童惊厥性癫痫持续状态的发病率、病因及短期临床结局:基于人群的前瞻性研究显示文摘Background:Convulsive status epilepticus is the mostcommon childhood medical neurological emergency,and is associated with significant morbidity and mortality. Mostdata for this disorder are from mainly adult populations and might not be relevant to childhood. Thus we undertook the North London Status Epilepticus in Childhood Surveillance Study (NLSTEPSS):a prospective,population-based study of convulsive status epilepticus in childhood,to obtain a uniquely paediatric perspective.Methods:Clinical and demographic data for episodes of childhood convulsive status epilepticus that took place in north London were obtained through a clinical network that covered the target population. We obtained these data from anonymised copies of a standardised admission proforma; accident and emergency,nursing,ambulance,and intensive-care unit notes; and interviews with parents,medical,nursing,and paramedic staff. We investigated ascertainment using capture-recapture modelling.Findings:Of 226 children enrolled,176 had a first ever episode of convulsive status epilepticus. We estimated that ascertainment was between 62%and 84%.The ascertainment-adjusted incidence was between 17 and 23 episodes per 100 000 per year. 98 (56%,95%CI 48-63) children were neurologically healthy before their first ever episode and 56 (57%,47-66) of those children had a prolonged febrile seizure. 11 (12%,6-18) of children with first ever febrile convulsive status epilepticus had acute bacterial meningitis. Conservative estimation of 1-year recurrence of convulsive status epilepticus was 16%(10-24%). Case fatality was 3%(2-7%). Interpretation:Convulsive status epilepticus in childhood is more common,has a different range of causes,and a lower risk of death than that in adults. These paediatric data will help inform management of convulsive status epilepticus and appropriate allocation of resources to reduce the effects of this disorder in childhood. | Chin R.F.

| 7 | 来曲唑或克罗米芬治疗不孕后怀孕的911例新生儿中的先天性畸形分析显示文摘Objective: To evaluate the incidence of congenital malformations among offspring of mothers who conceived with clomiphene citrate(CC) or with letrozole treatment for infertility. Design: Retrospective study. Setting: 5 fertility centers in Canada. Patients: 911 newborns from women who conceived following CC or letrozole treatment. Interventions: Examination of medical files of both mother and newborn, and cross-checked with the parents by telephone calls. Main Outcome Measures: Identified major and minor congenital malformations, birth weight, age of the mother, and type of treatment that led to the conception. Results: Overall, congenital malformations and chromosomal abnormalities were found in 14 of 514 newborns in the letrozole group(2.4%) and in 19 of 397 newborns in the CC group(4.8%). The major malformation rate in the letrozole group was 1.2%(6/514) and in the CC group was 3.0%(12/397). One newborn in the letrozole group was found to have a ventricular septal defect(0.2%)-compared to 4 newborns in the CC group(1.0%). In addition, the rate of all congenital cardiac anomalies was significantly higher(P: 0.02) in the CC group(1.8%) compared to the letrozole group(0.2%). Conclusion: There was no difference in the overall rates of major and minor congenital malformations among newborns from mothers who conceived after letrozole or CC treatments. However, it appears that congenital cardiac anomaly is less frequent in the letrozole group. The concern that letrozole use for ovulation induction could be teratogenic is unfounded based on our data. | Tulandi T. Martin J. Al-Fadhli R. R.F.

| 8 | 变质核杂岩中大规模低角度正断层作用的古地磁证据显示文摘对于沿低角度主剥离断层(正断层)是否出现大规模伸展变形还普遍存在争论.西部盆岭区出现的大量的新生代伸展变形以及与其有关的主剥离断层被普遍描述为沿地壳穹窿(即变质核杂岩)分布的近水平构造(MCCs).一类模式认为,MCCs代表由倾斜到近水平产状的原始高角度正断层圈定的地壳尺度的断块.较多的动力学模式指出,初始近水平断层由于均衡补偿而导致弯曲,到活动期的高角度正断层,最后转为近水平构造;这些模式均要求,MCCs主剥离层及其下盘具30°~60°的倾斜.我们认为,变质核杂岩剥离断层初始为近水平或低角度构造.我们利用南山未变形部分和南部盆岭区的标准新生代变质核杂岩(MCC)的古地磁资料对这些模式进行检验.对比均分时间间隔内古地磁场方向未能获得下盘倾斜的证据.因此,我们推断南山主剥离断层是以10°倾角的低角度伸展构造活动的. | R.F.
