Rice false smut is caused by ascomycete Villosiclava virens, whose potential alternative hosts have been assumed previ- ously. Here its potential alternative hosts were surveyed and identified from 2008 to 2013 in the main rice-growing regions in China. Two common weeds in paddy fields, Digitaria sanguinalis Scop. and Echinochloa crusgalli （L.） Beauv., were found to present the similar symptoms to smut diseases in a few individuals in 2012 and 2013 in Zhejiang and Sichuan provinces of China, respectively. After the examinations of the spore morphology, their infection and extension mode in hosts, pathogen cell wall components, and molecular identification, the two pathogens were identified to be the Basidiomycetes, Ustilago syntherismae and Ustilago trichophora, respectively. So far there has been no alternative host of V. virens to be identified in China. These suggest that the alternative hosts of V. virens, if they do exist, are not possible to play an important role in the pathogen life cycle and the disease epidemics.

The sclerotia of Villosiclava virens were found commonly in high altitude and the temperate regions, where the temperatures are relatively low in rice filling stage. To make sure if low temperature induce the sclerotial formation in V. virens, the inoculated rice panicles in laboratory and the diseased rice panicles cut from paddy fields were treated under different temperatures. The results showed that 3 days of night temperature at 15°C were enough to induce the sclerotial formation. The low temperature was much more effective for young balls with intact membranes. After appearance of chlamydospores on the ball surfaces, the sclerotium could not differentiate anymore. The sclerotia began to differentiate below the chlamydospore layer and gradually grew onto the ball surfaces. This suggests that low temperature in the early development stage of false smut balls is an important factor to induce the sclerotial differentiation, and rice cultivars with long growth periods are able to produce more sclerotium-bearing balls, which will produce mass of spores in paddy field in the coming year.

光电设备因太阳夹角变化、轨道遮挡等原因无法对卫星进行自动跟踪时,需要对卫星轨道进行预测。本文针对利用卫星轨道根数进行轨道预报时难以同时满足实时性和精度要求的问题,提出了一种新的基于轨道根数的卫星轨道预测方法。分析了卫星轨道的运行规律,根据低轨卫星的运行特点,利用椭圆曲线对卫星轨道进行预测,并对卫星轨道的轨道方程进行了近似处理。通过引入一些冗余变量简化了卫星轨道解算模型,在保证计算实时性的前提下,大大提高了轨道预测精度。实验显示:采用线性外推方法对卫星轨道进行预测时,预测5s后,轨道预测的偏差会增大到10″,而采用本文提出的基于轨道根数的卫星轨道预测算法,预测50s后的最大预测偏差均不超过2″,极大地提高了卫星轨道预测精度,实现了光电设备在无法对卫星进行自动跟踪时,能够对卫星进行"盲跟踪"。

为实现细菌的快速、低成本、高通量检测,设计并制备了一种阵列式柔性纸基SERS检测芯片。首先制备银溶胶,再利用激光打印和碳粉的疏水性,在纸基上分别构造隔离区与阵列检测区。在检测区循环滴加银溶胶,由于碳粉的疏水特性,将银溶胶液滴限制在检测区范围。一定温度下,银溶胶自然干燥即形成阵列式活性SERS检测芯片。利用罗丹明6G作为探针分子对纸基SERS芯片进行了表征,测试结果表明该芯片的检测限为10-8 mol/L,重复性测试的RSD约为11.85%。大肠杆菌SERS测试实验表明,该芯片可快速获得大肠杆菌的拉曼特征峰,无需对样本进行标记或复杂的前处理。该柔性纸基SERS芯片结构简单、制作快速、成本低廉,阵列结构可实现多参数的同时测量,有望应用于致病菌的直接、快速检测。

所谓法律修正案,是指全国人大及其常委会对宪法和重要基本法律进行修改时采用的方法以及最终发生法律效力的文本形式。关于法律修正案,法学界有"法律案意义上的修正案"与"制定法意义上的修正案"两种理解,它们各有所指,不应混淆。在我国,法律修正案还存在许多问题和不足,国家立法机关应认真总结我国改革开放30年来成功的立法经验,借鉴其他国家和地区的有益做法,进一步提高法律修正案的表述技术水平。

利用中国健康与养老追踪调查数据,以生命历程理论为视角,分析童年期家庭不良经历对个体成年早期生活机会的影响。研究发现童年期遭受忽视、父母精神异常等家庭不良经历对个体成年早期的生活机会具有显著影响,而遭受忽视强度以及父母精神异常的持续时间亦对成年早期的生活机会产生显著影响。相对于未发生忽视、父母精神异常等家庭不良经历的个体,经受家庭不良经历的个体,其生命事件发生时机出现延迟,且社会经济地位相对弱势,对成年早期的生活机会具有不利影响。上述发现揭示了童年期家庭不良经历对个体成年早期生活机会的微观作用机制,即童年期负向经历的存在和持续,通过作用与改变成年早期生命事件的发生时机、模式和机会结构,实现生命历程的累积效应。
