The thermal environment is an essential factor that affects sleep *** many circumstances,the bed microenvironment is more important than the ambient environment because of the large covered area of the human body and the close contact between the bedding system and the human *** main objective of this research is to establish an effective method to determine bedding system insulation.A thermal manikin was used in the measurement of bedding system *** different types of quilts,which were filled with cotton,polyester and duvet respectively,were chosen to be *** total ten different quilts with different materials and weights were involved in the *** regular arrangements of covers were chosen with coverage rates of 94.1%,85.9%,70.6%,and 54.4%to test.A total of 64 bedding systems were tested to build an effective method to determine the bedding system *** the basis of test data,the change of bedding system insulation with coverage was found to be *** fitting was applied to establish an insulation evaluation method for bedding system *** addition,the effects of quilt cover and sleepwear on bedding system insulation were discussed and thermal insulation increment caused by quilt cover and sleepwear were *** relationships between neutral indoor temperature and weight per unit area of the quilt for different coverage rates have been quantified based on existing subject *** research provides an effective method to determine bedding system insulation,which can be widely used in thermal comfort research and HVAC system design.

An endpoint damage oriented model for life cycle environmental impact assessment of buildings in China

引用

Chinese Science Bulletin 2008年第23期53卷 3762-3769页

作者： GU LiJing LIN BoRong GU DaoJin zhu yingxin Department of Building Science Tsinghua University Beijing 100084 China Building Energy Research Center Tsinghua University Beijing 100084 China

The midpoint impact assessment methodology and several weighting methods that are currently used by most building Life cycle assessment (LCA) researchers in China, still have some shortcomings. In order to make the evaluation results have better temporal and spatial applicability, the endpoint impact assessment methodology was adopted in this paper. Based on the endpoint damage oriented concept, four endpoints of resource exhaustion, energy exhaustion, human health damage and ecosystem damage were selected according to the situation of China and the specialties of the building industry. Subsequently the formula for calculating each endpoint, the background value for normalization and the weighting factors were defined. Following that, an endpoint damage oriented model to evaluate the life cycle environmental impact of buildings in China was established. This model can produce an integrated indicator for environmental impact, and consequently provides references for directing the sustainable building design.

原发性中枢神经系统淋巴瘤(PCNSL)是高度侵袭性恶性肿瘤, 多数化疗药物难以穿过血脑屏障, 因此PCNSL治疗难度大, 复发率高, 预后差。早期识别复发并开始挽救治疗是改善PCNSL患者预后的关键。脑组织活组织检查虽是识别复发的金标准, 但操作失败及出现并发症的风险较大。无创影像学技术有助于PCNSL复发的早期识别, 为指导复发患者及时调整治疗方案提供重要依据, 但目前用于监测PCNSL复发病灶的影像学手段仍无统一的评判标准。随着对PCNSL病理生理机制研究的深入, 生物标志物检测成为识别复发的新手段, 但仍需更多临床证据支持。
