Abstract: 共培养条件下,采用叶绿素含量和叶绿素荧光参数研究穗花狐尾藻分泌的化感物质对铜绿微囊藻光合效率的影响,其中叶绿素荧光参数包括qN(非化学淬灭)、YⅡ(有效量子效率)、Fv/Fm(最大量子产量)、F′v/F′m(光系统Ⅱ有效量子产量)和快速光响应曲线. 3 d共培养处理期间,铜绿微囊藻叶绿素含量及叶绿素荧光参数都受到不同程度的影响,不同参数表现出了不同的灵敏性.处理第2 d时,10.0 g/L穗花狐尾藻体系中铜绿微囊藻叶绿素含量抑制率为20.80%,表现出了显著的抑制(P<0.05).而铜绿微囊藻叶绿素荧光参数出现显著降低的时间更早,处理第1 d时,qN和YⅡ在5.0 g/L穗花狐尾藻的浓度下抑制率分别为15.59%和13.00%,Fv/Fm和F′v/F′m在10.0 g/L的浓度下抑制率为15.87%和12.07%,均表现出来明显的受抑制作用(P<0.05).处理第3 d时,铜绿微囊藻的快速光响应曲线及根据该曲线计算得到的3个参数都受到了显著的抑制(P<0.05).结果表明,光合作用是穗花狐尾藻抑制铜绿微囊藻生长的重要对象之一,4个叶绿素荧光参数是相对于叶绿素含量更灵敏的指标,其中qN最灵敏.

Abstract: 摘要 尖牙阻生是口腔中常见的牙齿发育障碍之一,其病因和发病机制尚未明确,治疗选择多样。本文通过查阅尖牙阻生相关文献,介绍了尖牙阻生的病因、对口颌系统的危害、诊断及治疗方法,以期在临床中对阻生尖牙的诊断及治疗提供参考。尖牙阻生病因与硬组织障碍、局部病理性因素、发育因素、遗传因素等有关;全颌曲面断层片及锥形束CT(cone beam CT,CBCT)是必要的诊断手段;治疗以正畸牵引导萌为主要方法,早期检查和治疗有助于口颌系统的稳定平衡及邻牙的健康

Implementation of an improved Chord algorithm in the file sharing system
Chord改进算法在文件共享系统的实现

GAO Ji-rong,SU Zheng-lin,<br>高集荣,
计算机应用 , 2006,
Abstract: Chord is a kind of comparatively effective P2P route algorithm, and it can locate the target resources quickly. But because of the over low utilization of the message during transmission, the routing table suffers serious information redundancy and great network maintenance is needed. Therefore, this text put forward an improved Chord arithmetic, and resolved some existing problems. As a result, the network search efficiency was raised and fault-tolerance ability of the network was strengthened. The improved one was implemented in a design of the file sharing system and proved to be effective.
A SPIN-ONE QUENCHED BOND RANDOMLY DILUTED IS1NG MODEL ON A HONEYCOMB LATTICE

Abstract: A new decoration method is proposed which can achieve an exact mapping between the quenched bond randomly diluted spin-1 Ising model on a regular lattice in the subspace: exp(K)cosh (J) =1 and a certain class of mixed-spin quenched site randomly diluted decorated-lattice problem. Using this mapping in conjunction with the annealed model solution for the decorated-lattice problem, we have obtained the approximate results for the quenched bond randomly diluted spin-1 Ising model on the honeycomb lattice. The critical temperature and the magnetization of the diluted system as functions of bond concentration are calculated in detail.
