连续激光引起高空中动态靶材破坏的理论计算

本文在文献[1]和[2]的基础上,考虑动态靶目标是受载结构的影响,综合考虑大气吸收、散射、湍流及热畸变效应对激光传输的影响,计算了连续激光引起高空中动态靶目标的破坏阈值。     

榆树林油田砂岩储层敏感性研究

榆树林油田储层粘土矿物含量较高，各种注入条件和施工条件都会对该储层造成相应的伤害，应采取相应的防护措施，为防止速敏的发生，储层的注水速度应控制在临界流速（1.0mL/min）以下，在油井转注时，可先注入1.09PV的含粘土稳定剂的进行处理，以提高产量或注入量，注入阴离子表面活性剂配置的活性水再注入地层水，不能增加地层水的渗透率，该项试验研究对指导榆树林油田的开发具有重要的意义。     

血液流速测量中血红细胞的多普勒信号

采用双光束干涉条纹模型，用光散射理论得出了激光多普勒测速中大型散射粒子的多普勒信号幅值的表达式：用数值解法求得多普勒信号幅值随散射粒子半径变化的曲线。红血球直径即使比干涉条纹宽度大10倍，也会有良好的多普勒信号。给出了实测的血流多普勒信号。     

对提高节目技术质量的意见和建议

随着电视事业的发展，电视这一特殊传播媒介越来越为人们所重视，电视观众对电视节目质和量的要求也越来越高。在这一前提下，中央电视台在一九九五年新增设了包括电影频道、文艺频道、体育频道、少儿军事农业科技频道、戏曲音乐频道共五个卫星频道，加上原先的一、二、四套节目，每天共有八个频道，总计约140多小时的节目量进行播出。在这种情况下，虽然技术系统也相应地增加了一些设备和人员，但仍无法完全满足编播部门如此迅猛的发展。因此，确保技术质量和进一步提高工作效率就成了当前一个突出的课题。     

Characterization of a cartilage-derived 66-kDa protein (RGD-CAP/beta ig-h3) that binds to collagen

Malignant human gliomas are the most common forms of primary tumors in the central nerve system. Due to their location and invasive nature, treatment so far has been mainly palliative. Thus, understanding the molecular detail of tumor transformation and progression is crucial for developing effective therapeutic strategy for this fetal tumor. Among the genetic alternations found in these tumors, p53 inactivation and PDGF/PDGFR activation represent the early events, and the loss of chromosome 10 and gene amplification and rearrangement of EGFR represent the late events. Studies with both glioma cell lines and primary tumor tissues have strongly suggested that TGF-alpha and EGFR function as an important autocrine loop in supporting proliferation of human glioma, especially in high grade glioma, since elevated TGF-alpha expression is also found in these high grade tumors. Furthermore, down regulation of the expression of TGF-alpha by antisense constructs has been shown to inhibit several types of human tumor cell growth including glioma. Other means of therapeutic approaches using this autocrine loop as a target also include the use of monoclonal antibodies and their cytotoxic conjugated. Considerable understanding of the EGFR-mediated signal transduction pathways has become available recently, which including GRB2/mSOS1 mediated MAP kinase activation; JAK/STATs pathway; PLC-gamma pathway. However, much work still needs to be done before a specific component of these pathways can be applied for effective control of tumor growth in the clinic.
