    • A polymer fiber is formed by hydrodynamic spinning. Fluids are forced to flow through a conduit to form a laminar flow comprising three or more layers of generally coaxial fluid flows, at respective flow rates selected to define a cross-section of a tubular middle layer of the fluid flows. The middle layer comprises a cross-linkable polymer precursor. Another layer of the fluid flows comprise a cross-linking agent. The polymer precursor, cross-linking agent and fluids are selected to prevent substantial diffusion of the polymer precursor away from the middle layer, and to allow a portion of the cross-linking agent to diffuse from the another layer into the middle layer to facilitate cross-linking of the polymer precursor in the middle layer to form a tubular polymer layer in a polymer fiber. The polymer layer thus has a cross-section generally corresponding to the cross-section of the middle layer.
    • 聚合物纤维通过流体动力纺丝形成。 流体被迫流过导管以形成包含三层或更多层大体上同轴的流体流的层流,其各自的流速被选择为限定流体流的管状中间层的横截面。 中间层包含可交联的聚合物前体。 流体流的另一层包含交联剂。 选择聚合物前体,交联剂和流体以防止聚合物前体远离中间层的实质性扩散,并且允许一部分交联剂从另一层扩散到中间层以促进交叉 在中间层中连接聚合物前体以在聚合物纤维中形成管状聚合物层。 聚合物层因此具有一般对应于中间层的横截面的横截面。

    • The invention discloses a method for implementing an online secure payment, which comprises steps of: transmitting to a dedicated operating system a secure payment request page for goods which is generated in a general operating system; and completing a payment operation in the secure payment request page of the dedicated operating system, after switching from the general operating system to the dedicated operating system. The invention further comprises a client system for implementing an online secure payment. In the invention, the general operating system for general operations is distinguished from the dedicated operating system for secure payment operations, and the security for the network payment is further enhanced by configuring the firewall and monitoring processes in the dedicated operating system. Furthermore, it is not necessary to make any modification on the existed network transaction system when the technical solution of the present invention is applied, the cost may be reduced and the technical solution of the present invention is facilitated to be deployed and spread.
    • 本发明公开了一种实现在线安全支付的方法,包括以下步骤:向专用操作系统发送在一般操作系统中产生的商品的安全支付请求页; 并且在从一般操作系统切换到专用操作系统之后,在专用操作系统的安全支付请求页面中完成支付操作。 本发明还包括用于实现在线安全支付的客户端系统。 在本发明中,一般操作的一般操作系统与用于安全支付操作的专用操作系统不同,并且通过在专用操作系统中配置防火墙和监视进程来进一步增强网络支付的安全性。 此外,当应用本发明的技术方案时,不需要对存在的网络交易系统进行任何修改,可以降低成本,并且有助于部署和扩展本发明的技术方案。
