中国降水主要受到西风和季风环流的共同影响,表现出显著的年循环特征。本文基于1961~2020年CN05.1逐日降水资料和JRA55、CRU、HadISST再分析资料,采用谐波分析、相关和回归统计方法,分析了过去60年的东亚夏季风(中国雨季)的建立(开始)、撤退(结束)和持续时间等年循环参数趋势的变化特征。结果显示,自1961年以来,东亚夏季风有建立时间提前,撤退时间推后,持续时间增长的趋势,每十年分别达到了3.54、1.64、5.18天。1999年前后22年我国雨季也存在趋势变化,且在空间上存在显著差异。最近22年(1999~2020年),我国雨季提前主要集中在东北东部、青藏高原东部、西北北部地区,提前时间达5天以上,部分地区超过了20天。雨季滞后主要集中在青藏高原东北,长江以北和西部地区,时间超过了10天。雨季持续时间增加主要集中在青藏高原东北部、我国长江以北、东北东南部地区,时间超过15天以上,部分地区超过25天。研究发现,4月份环贝加尔湖地表气温增加及其伴随的局地反气旋性环流异常,是东亚夏季风建立和我国雨季开始时间提前的关键,而10月份的西北太平洋海温增暖及其伴随的西北太平洋副热带反气旋的异常是导致东亚夏季风撤退和中国北方雨季变长的关键。

研制具有较大活性面积的钙钛矿太阳电池对领域面向产业化的发展具有重要意义.当前,大面积钙钛矿太阳电池的性能与小面积钙钛矿太阳电池之间仍存在较大差距.本文提出一种在透明导电薄膜衬底上预先原子层沉积TiO_(2)薄层的策略,有效避免了衬底局部突起与钙钛矿吸光层直接接触导致的漏电现象,提升了小面积器件制备工艺的重复一致性.改善的电子输运和光管理过程也提高了小面积器件的效率.更重要的是,本文基于原子层沉积的TiO_(2)开展了0.5 cm^(2)大面积钙钛矿太阳电池的研究,通过优化TiO_(2)层的厚度,研制出光电转换效率高达24.8%的冠军器件(第三方认证效率24.65%),器件的制备工艺也表现出较好的重复性.此外,原子层沉积了TiO_(2)缓冲层的电池器件在氮气氛围下存储1500 h后仍然能够保留初始性能的95%以上.总之,在粗糙衬底上预先原子层沉积TiO_(2)薄层可以有效抑制局部漏电通道的产生,有利于制备高性能的大面积钙钛矿太阳电池.

Carmine spider mites （Tetranychus cinnabarinus） and cotton aphids （Aphis gossypii） are both serious pests of cotton, and cause reductions in yields of this key agricultural crop. In order to gain insights into how plant defense responses induced by one herbivore species affect the behavior and performance of another, we examined how infestation with T. cinnabarinus influences the development of A. gossypfi using cotton as a model. In this study, we measured the activities of several important biochemical markers and secondary metabolites in the leaves of cotton seedlings responding to infestation by T. cinnabarinus. Furthermore, the influences of T. cinnabarinus infestation on the development ofA. gossypfi in cotton were also examined. Our data showed that the activities of several key defense enzymes, including phenylalanine ammonia-lyase （PAL）, peroxidase （POD）, lipoxygenase （LOX）, and polyphenol oxidase （PPO）, were substantially increased in cotton seedlings responding to spider mite infestation. Further, the contents of gossypol and condensed tannins, key defensive compounds, were significantly enhanced in leaves of cotton seedlings following T. cinnabarinus infestation. Moreover, the T. cinnabarinus-induced production of defense enzymes and secondary metabolites was correlated with infestation density. The developmental periods of A. gossypii on cotton seedling leaves infested with T. cinnabarinus at densities of 10 and 15 individuals cm-2 were 1.16 and 1.18 times that of control, respectively. Meanwhile, the mean relative growth rates of A. gossypfi on cotton leaves infested with T. cinnabarinus at densities of 8, 10 and 15 individuals cm-2 were significantly reduced. Therefore, these data suggested that the developmental periods of A. gossypfi were significantly lengthened and the mean relative growth rates were markedly reduced when cotton aphids were reared on plants infested with high densities of spider mites. This research sheds light on the role that in

眼眶淋巴瘤(OLs)是成年人常见的眼眶恶性肿瘤。迄今已提出许多OLs的治疗方法,包括放射治疗、化学疗法、免疫治疗、抗生素治疗、手术或联合治疗等,但最佳治疗方案的选择仍然是一项涉及多学科的任务。依据组织病理学分型和临床分期的不同,OLs将采用不同的治疗方案。放射治疗通常是原发性低级别OLs的首选治疗方案,特别是maLT淋巴瘤;其他非maLT组织学亚型的OLs也可选择放射治疗,但其疗效通常不如maLT淋巴瘤。而高级别以及其他复发或难治性OLs常选择化学疗法。目前,利妥昔单抗联合CHOP的化学免疫疗法可明显改善高级别OLs的预后。而抗生素可能对鹦鹉热衣原体感染相关的maLT淋巴瘤患者中的一小部分有效。研究显示,OLs病理组织学分型和临床分期也是影响其预后的主要因素。高级别淋巴瘤预后较差,而低级别淋巴瘤预后良好;年龄、性别、疾病原发部位和各种治疗方案等因素也与其预后密切相关。本文对国内外OLs治疗及预后因素的相关研究进行综述,以期为临床治疗方案的制定和预后效果评估提供参考。

Understanding phosphorus dynamics in marine environment is of great importance, and appropriate trac- ers for phosphorus cycling in oceans are invaluable. In this study, two methods were developed for extrac- tion, purification, and determination of naturally occurring ^32p and ^33P in rainwater, marine plankton and sediments using both a low-level beta counter （LBC） and an ultra-low-level liquid scintillation spectrome- ter （LSS）. Blanks, chemical yields and counting efficiencies were quantified for both methods. The chemical purification of ^32P and ^33P separated by both procedures was validated by their decay curves. The absorber thickness of aluminum for LBC was assessed as 39.2 mg/cm2. ^32P and ^33P specific activities in some rain samples were determined by both methods and showed good consistent results. The advantage of the LSS over the LBC is apparent in its high counting efficiency and in determining samples with high concentration of stable phosphorus. However, when measuring environmental samples with low concentration of stable phosphorus, such as rainwater, both methods can be used and each has its distinct advantage.
