By a method using fraction precipitation of ammonium sulphate, ion exchange, modified hydrorylapatite and gel filtration chromatography, we separated and purified two kinds of phycoerythrin(R-PE and r-PE) from Corallina officinalis . The purity standard(ratio of ODs65/OD2go) of R-PE reaches to 11, which is the highest purity comparing with the reported purity of phycoerythrin.

经盐析、离子交换层析、羟基磷灰石吸附层析和凝胶过滤层析等分离纯化方法，从珊瑚藻中分离纯化出两种藻红蛋白，其中R-PE纯度OD_(565／OD_(280)高达11左右，是目前国内外报道的藻红蛋白中纯度最高。

考察了交联剂及致孔剂用量对色谱柱压力的影响，发现：随着交联剂用量的减小，致孔剂用量的增大，柱压下降；当交联剂和致孔剂用量达到一定水平后，柱压变化不再明显，但柱体机械强度降低。

The development of network and communication technology provide convenient and shortcut approach to exchange information and share resource. On the other hand, there has been the problem how to manage the network since the network appeared. SNMP emerging as the times require with the development of Internet provides the universal methods to get and configure the information of network management from the objects managed. It is a discussable problem how to understand SNMP deeply and apply SNMP to practice effectively.

网络和通信技术的发展，一方面为信息的交流，资源的共享带来了方便、快捷的途径；另一方面，从网络出现起，就存在着网络管理的问题，在Internet发展中应运而生的简单网络管理协议定义了从被管理对象获取和配置网络管理信息的简单而功能强大的通用方法，然而要透彻地理解它和有效地应用于网络管理的实践中是值得研究的问题。

In this paper, by considering the convenience of consumers, we use group blind signature technology with the character of hash chain to create the dividable and anonymous e-cash. Thus the users can consume not only in the home mobile domain but also visit mobile domain without register and authentic. We use off-line e-cash to increase the efficiency of payment exchange. Under the fair principle of all participators, we set a convenient and secure mobile payment.
