In general, it was shown that the combinatorial vaccine with HBsAg and HBcAg can induce strong and homogenous humoral and cellular responses, and conduce to eliminate the endocellular HBV virus and break immunologic tolerance which existed durative in chronic hepatitis B patients. So it can offer the new thought and theory foundation for the further study to exploit the Hepatitis therapeutic vaccine.

总之，本课题工作表明，用CS1与HBsAg联合，具有良好的体液免疫与细胞免疫效果，有助于清除HBV病毒并有希望打破HBV感染引起的慢性乙型肝炎病人持续

On the basis of electrical network characterization, Chapter 5 presents a new principle to detect PCB's fault first time. Three methods of online test for electrical network characterization are described in detail. Then, a hierarchical, combinatorial approach is firsfly presented. The test efficiency of this method is studied also. The experiment result shows that the new approach can greatly enhance the test efficiency of fixtureless tester under the requirement of 100% test for PCB's connections.

本文第5章利用集成电路的输出特性，首次提出了一种新的印刷电路板连接故障的检测原理，给出了三种印刷电路板电气网络输出特性的在线测试方法；在此基础上，首次提出并实现了基于飞针式在线测试仪的层式组合测试思想，研究了这种方法的检测效率；应用实例表明这种方法在不降低对印刷电路板连接故障100％测试的要求下，可以有效地提高飞针式在线测试仪的检测效率。

In the key step of this method (the process of contour tracking), the paper puts forward the concept of grid right-correlation flag to determine the initial segment of tracking curve. In the tracking procedure, the trend of subsequent points are determined by the combinatorial values of neighborhood cells, and a method is designed to avoid contours crossing. In order to obtain high-quality contour line, it adopts it adopts the linear interpolative method to show a contour chart of accurate localization and better visual effect.

在该方法的关键过程中，提出栅格右关联标志的概念，并据此确定初始追踪段；追踪过程中依据邻域栅格值的组合特征确定后续点的走向，设计了避免等值线交叉的处理措施；为获得高质量的等值线图形，采用线性插值方法，得到准确定位和视觉效果较好的等值线图形。
