An Acoustic Converter Used to Measure Ionizing Radiation Energy Loss

A monitor is proposed based on ultrasonic production when ionizing radiation passes through a medium. The recording element is a 0.2 mm aluminum plate mounted in a ceramic acoustic converter AC in the form of a wedge of thickness 2 mm. The low plate thickness minimizes the beam parameter distortion, while special technology used in the AC provides high sensitivity. The device has been calibrated in the proton beam from the ITEP accelerator at 200 MeV with 2·10⁹–6·10¹⁰ particles in a pulse and a pulse length of 70 nsec.     

洼60-H26水平井套铣打捞技术

洼60-H26井是一口中曲率水平井,设计井深1 922 m,由于地面条件的限制,设计采用三维井眼轨道。该井水平段在钻至井深1 801 m时,发生卡钻事故。在卡钻事故处理过程中,采用测卡、爆炸松扣技术取出上部钻具后,应用了不同规格的套铣管对被卡钻具进行套铣,采用间歇式套铣方式实现了大斜度井段(45°-90°)的安全套铣,采用短套铣管完成了时水平井段内φ215．0 mm稳定器的套铣,采用φ228．6 mm套铣管成功套铣水平井段被卡LWD仪器,最后通过震击器震击成功解卡。详细介绍了洼60-H26水平井卡钻事故的处理过程,分析了在水平段处理卡钻事故的难点。该井处理卡钻事故的经验,对以后水平井施工中处理井下事故、打捞贵重仪器具有借鉴价值。

Verbal Representation and Therapeutic Change in Anaclitic and Introjective Inpatients.

This study examined the relation between changes in clinical functioning and changes in verbal expression in 81 seriously disturbed and treatment-resistant young adults seen in a comprehensive, psychoanalytically oriented inpatient treatment. Clinical functioning was evaluated with a battery of clinical and social measures. Verbal representations were assessed using computer-assisted scoring of Thematic Apperception Test responses. Changes in the frequency of verbal content and style in the narratives of these patients covaried with changes in clinical functioning. Significantly different covariations of verbal and clinical change, particularly differences in covariates of referential activity, were found for patients with anaclitic versus introjective personality configurations. The implications of these findings for understanding and treating severe psychopathology are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

不同类型染料的缺氧生物降解性能研究

对24种常用染料在缺氧条件下的降解性能作了研究，探讨了不同类型、不同化学结构染料生物降解性的内在影响因素，得出了碱性染料和X型染料最易降解，K型染料次之，M型、KN型再次之。此外，染料的分子量、取代基数量、发色母体基团等也是影响染料缺氧生物降解性能的一个重要因素。     

液相颗粒包裹法制备PbNb2O6微粉的研究

本文介绍了一种采用液相颗粒包裹技术制备功能陶瓷微粉的新方法.这种方法有如下特点:(1)方法简便,不需要特殊的设备,便于扩大应用于工业生产;(2)粉体颗粒尺寸小而均匀;(3)粉体化学组成偏离小、且均匀;(4)适应性强,从双组分至十多组分的材料微粉制备均可采用;(5)特别适用于一些含有难溶组分、用液相法无法制备的材料.本工作采用这一方法,成功地制备出 PbNb_2O_6微粉,其平均腰粒尺寸<0.5μm,分散性及化学均匀性好,烧结活性高,烧结温度可以降低近100℃,瓷坯密度可达理论密度的96%以上.
