孔隙度校正缺乏理论依据

储油岩石一般为致密介质。致密介质在应力作用下，以本体变形（弹性变形）为主，孔隙度不发生变化。油气储量计算时，地面实测孔隙度不发生变化。油汽储量计算时，地面实测孔隙度不需要进行校正。传统的孔隙度校正无形中损失了一部分地质储量，同时为确定校正值大小也浪费了大量人力和物力。致密岩石弹性变形过程中的孔隙度不变性原则将给储量计算带来很大的方便。

浙江泵业何去何从?

浙江省已经成为我国最大的泵产品制造省份，温州、台州、杭州是浙江省泵制造业的三个生产基地，永嘉还被中通协授予“中国泵阀之乡”的称号，然而许多浙江籍泵企业领导都有这样的感慨；企业的初期发展非常快，但发展到一定规模后，速度就停止下来了，专家牟介刚一直关注浙江泵业的发展，在本文中，分析了浙江泵业普遍存在的深层不足，并给出了今后如何发展的措施建议，值得浙江的泵业企业家们关注。     

Faculty and Student Attitudes Toward Community Service: A Comparative Analysis

The Humanitarian Engineering initiative, sponsored by the William and Flora Hewlett Foundation, at the Colorado School of Mines, is creating a program that will support engineering students in understanding their responsibility for solving community development problems that exist throughout the world. As part of this effort, data has been collected on faculty and student attitudes using the ‘Community Service Attitudes Scale,” developed and validated by Shiarella, McCarthy, and Tucker. During the fall 2004, 78 students and 34 faculty members responded to this instrument. Statistically significant differences were found between the attitudes of students and faculty, males and females, and among different age groupings with respect to service activities. A general finding was that faculty displayed better attitudes toward community service than the students.     

氧化物共还原制取W-Cu和Mo-Cu复合材料的研究

近些年来,国内外研究了一些制备高分散度W/Cu和Mo/Cu复合粉末的方法,高分散度的粉末具有高的烧结致密度,用氧化物共还原粉末可在较低温度下进行烧结得到接近和达到100%的理论密度。这样的复合材料有细而均匀的组织和较好的性能。本文报道近来的研究状况,并就共还原法所用的前驱体原料种类、工艺条件、粉末特性和复合材料的性能进行评述。

Blood parameter and heart rate response to training in Andalusian horses

The psychopathology and associated disabilities experienced by persons with schizophrenia have only partially responded to conventional pharmacological and psychosocial treatment approaches. Biobehavioral treatment and rehabilitation employs behavioral assessment, social learning principles, skills training, and a focus on the recovery process to amplify the effects of pharmacotherapy. Utilizing the Medline database, we review a selection of English-language studies published from 1970 to 1994 that support the effectiveness of each of the components of biobehavioral therapy, such as case management, psychopharmacology with behavioral assessment, psychoeducation, family involvement, and social skills training. An integrated biobehavioral therapy directed toward early detection and treatment of schizophrenic symptoms, collaboration between consumers and caregivers in managing treatment, family and social skills training, and teaching coping skills and self-help techniques has been documented to improve the course and outcome of schizophrenia, as measured by symptom recurrence, social functioning, and quality of life. A case vignette is presented to illustrate the successful integration of biobehavioral therapies into a treatment system that focuses on consumers' attempts to become increasingly responsible for recovering from illness.     

热湿传递中交叉效应的探讨

讨论了在热湿同时传递过程中Ｓｏｒｅｔ效应和Ｄｕｆｏｕｒ效应的影响程度，实验证明，湿空气中热湿交叉效应的影响程度远远大于其它可无限溶混的非极性混合气体。实测所得的质导热系数Ｋｃ测和热导质系数ＤＴ测要比原理论推算值大１￣３个数量级。     

海南省水资源配置决策的层次分析模型研究

海南省特殊的地理位置决定了其水资源配置问题的独特性,在水资源配置方案中,呈现出多阶段、多层次、多目标、多决策主体的特点,使得水资源配置模型难以确定并给决策带来了很大的风险性。本文研究了适合于海南省水资源优化配置所需的评比指标,对层次分析法加以改进,结合海南省水资源配置问题的决策要求,用改进后的层次分析法进行评价指标优化计算,最终得出了较为满意的结果。     

Optimization techniques for curved path computing

Participating media with an inhomogeneous index of refraction make light follow curved paths. Simulating this in a global illumination environment has usually been neglected due to the complexity of the calculations involved, sacrificing accurate physical simulations for efficient visual results. This paper aims to simulate non-linear media in a more reasonable time than previous works without losing physical correctness. Accuracy is achieved by solving the Eikonal equation of geometrical optics, which describes the path followed by a light beam that traverses a non-linear medium. This equation is used in the context of a photon mapping extension.
