由于卵泡功能丧失而导致的月经永久停止称为绝经。临床上，40岁或50岁以上的妇女，除外其他的生理或病理因素，连续12个月闭经，即认为是绝经。平均在绝经前4年左右，多数妇女开始出现卵巢功能的内分泌、生物学和临床特点改变。一个共同特点就是既往月经规律的妇女出现月经周期紊乱。这一变化标志着进入绝经过渡期（围绝经期）。

在新材料成功开发应用的同时,人们对传统材料——钢材的要求也日益增加。汽车制造商希望在汽车制造中使用既薄又坚因的新型钢材,使其生产的车辆既高效又环保;其它工业领域也从双相钢、多相钢或高强度钢如 Dp,TWIX,TRIp 中获益匪浅,制造出高强度、高承载的结构部件和高吸收能量的设备部件。现代轧钢自动化系统对于钢材质量的稳定与生产的平稳是至关重要的。自动化系统除了完成热轧带钢生产的顺序和执行机构的控制之外,对数学模型和工艺控制的不断发展也至关重要,尤其对于热轧带钢行业的领先企业更是如此。除了钢材的合金元素外,轧制冷却对这些钢材的性能也是决定性的。因此,高精度的轧制冷却温度和灵活的控制方案是极其重要的。然而,以前的所有冷却模型,存在一个通病就是,由纯粹表象决定金属晶相的转换过程,这需要准确计算温度曲线, 特别是时间和温度过程关系的在线控制。西门子 I＆S 现在已开发了基于所谓的 Gibbs 自由焓的新的冷却控制系统, 以便根据热动态模型非常精确计算出金属相变过程。借助于模型预测控制功能,控制冷却段的温度变化时间、优化冷却,使全部带钢温度变化落入规定的范围内。对于受阀门和/或水流量、机械布置限制的轧机,西门子开发了现代化的层流冷却系统,采用新的布置和新型集管,如此一来,西门子开发的新冷却系统,不仅适用于按照新要求设计的机械设备和冷却装置,也可适用于旧设备冷却装置的改造。

宫颈原发性神经外胚层肿瘤1例报道

世界核心医学期刊文摘（妇产科学分册） 2006年第1期2卷 49-50页

作者： Snijders-Keilholz A. Ewing p. Seynaeve C. burger C. W. 杨晓梅(译) 马超(校) A. Snijders-Keilholz Erasmus University Medical Center Daniel Den Hoed Cancer Center PO-Box 5201 3008 AE Rotterdam Netherlands 不详

Background. peripheral primitive neuroectodermal tumor (pNET) of the cervix uteri is extremely rare. Between 1987 and 2002, there have been eight cases described in the English literature. The treatment policies in these eight cases differed considerably, partly due to the rarity of the disease and to differing time periods of diagnosis and treatment. Case. At the end of 2002, a 21- year- old woman presented with a pNET of the cervix uteri at our institute, the Erasmus medical Center. For the appropriate treatment in this case, we reviewed the literature and decided that the treatment should be different from the local surgical treatment followed by additional treatments as most of the earlier reports describe. Conclusion. In view of the current knowledge of pNET belonging to the family of Ewing’ s sarcoma, and the improvement of treatment outcome in these tumors due to dose-intensive neo-adjuvant chemotherapy, patients with pNET of the cervix should be treated in accordance to the protocol for bony Ewing’ s sarcoma with multimodality therapy by means of induction chemotherapy, surgery, and consolidation chemotherapy.

CSES(China Seismo-Electromagnetic Satellite) is a mission developed by CNSA(Chinese National Space Administration) and ASI(Italian Space Agency), to investigate the near-Earth electromagnetic, plasma and particle environment, for studying the seismo-associated disturbances in the ionosphere-magnetosphere transition zone. The anthropogenic and electromagnetic noise,as well as the natural non-seismic electromagnetic emissions is mainly due to tropospheric activity. In particular, the mission aims to confirming the existence of possible temporal correlations between the occurrence of earthquakes for medium and strong magnitude and the observation in space of electromagnetic perturbations, plasma variations and precipitation of bursts with highenergy charged particles from the inner Van Allen belt. In this framework, the high energy particle detector(HEpD) of the CSES mission has been developed by the Italian LImADOU Collaboration. HEpD is an advanced detector based on a tower of scintillators and a silicon tracker that provides good energy and angular resolution and a wide angular acceptance, for electrons of 3–100 me V, protons of 30–200 me V and light nuclei up to the oxygen. CSES satellite has been launched on February 2^(nd), 2018 from the Jiuquan Satellite Launch Center(China).

Environmental assessment of impacts, management, and policy are important aspects of protection of human health and the environment. Assessing the impacts of human activities requires selection of bioindicator species that can be used to assess, manage, and develop public policies that ensure ecosystem integrity, and therefore sustainability of social, cultural, and economic systems. With the use of Chinook Salmon (Oncorhynchus tshawytscha), pacific Cod (Gadusmacrocephalus), mallard (Anas platyrhynchos), and Red Knot (Calidris canutus rufa), we explore assessment and measurement endpoints, and their relationship to management and development of public policy. This combination of fish and birds provides a diversity of life histories, ecosystem roles, human values, and resource use to explore their use as bioindicators and endpoints. It also allows examination of 1) conservation and protection of species and biodiversity, 2) protection of ecosystems, 3) provision of goods and services, and 4) societal well-being.

光伏阵列和逆变器的市场正在以高达40%的年平均增长率迅猛发展。2007年总的市场大约为2.5GW,而且在2007年年末的总装机容量将达到约10Gw。光伏逆变器将阵列输出的直流电流转化成交流电流,并且反馈回电网。逆变器拓扑结构有三种基本形式:带低频(50/60Hz)变压器的逆变器、带高频变压器的逆变器、无变压器的逆变器。无变压器的逆变器在欧洲市场上占主导地位,市场份额约为80%,在日本市场上占有接近50%的份额,而在美国由于国家标准的要求,只能使用带变压器的逆变器。无变压器的逆变器的效率高达98%。高效率的无变压器逆变器这是一个国际的发展趋势。随着技术发展,通过采用中点钳位拓扑(NpC)和新型电力半导体器件材料如碳化硅,将使得逆变器效率达到98.5%。
