In this paper, by using the de Rham model of chen-Ruan cohomology, we define the relative chen-Ruan cohomology ring for a pair of almost complex orbifold （G, H） with H being an almost sub-orbifold of G. Then we use the Gromov Witten invariants of G, the blow-up of G along H,to give a quantum modification of the relative chen-Ruan cohomology ring H^R（G, H） when H is a compact symplectic sub-orbifold of the compact symplectic orbifold G.

The study of the moduli space plays an important role in classical enumerative geometry and its interaction with string theory in physics. Given X=[P1/Zr] and let x＇ = （[0]a , [∞]b） the 2-tuple of twisted sectors on X , we construct in this paper two different compactifications of the moduli space M0,2（X, d[P1/Zr], x＇）： Nonlinear Sigma Model Mx＇d and Linear Sigma Model Nx＇d . Relations between Mx＇d and Nx＇d are studied and a new gluing recursive relation on Nx＇d is derived from Mx＇d due to virtual localization formula.

As remote control for electric home appliances thro ug h the Internet becomes more common, many compannies today launched a new corpora te initiative to develop advanced embedded solutions for Internet connectivity t hat can be applied to a boundless number of products such as information applian ces and non-PC devices. The most representative products are CMX-MicroNet which provides true TCP/IP ca pabilities for 8-bit and 16-bit microprocessors and eZ80Internet Engine which provides easy Internet connectivity for 8-bit devices. Pushed by the extraordinary success of these products, we have developped a kin d of embedded TCP/IP chip based on DW8051 *** some significant features su ch as establishing several connections at a same time, low-cost and high speed, we hope it will possess its own "embedded Internet" market. There are three most common application fields of the embedded TCP/IP chip. a) connection embedded microcontroller-based devices such as electric home appl iances to Internet b) allowing the remote control and monitoring of devices in the field via the In ternet c) allowing a remote device to send messages via email to, for example, a servic e centre. The working process of communication with embedded TCP/IP chip is described as f *** it starts to work, it keeps on waiting the connection request from t he host and getting the requisite information such as destination IP address,des tination port through the host *** it should connect to the ISP. A di al-up modem makes the connection and then the connection is negotiated. When bo th end systems begin to communicate, the chip keeps on transmitting datagram bet ween them and inspecting every phase of the connection to ensure the communicati on. The innovation of this design is the successful usage of separate CRC module and UART module, as can improve the speed and performance of this chip greatly. Suc h kind of efficiency improvement brought by the proposed design has been proved

A novel method to prepare guanidine substituted aminoglycoside derivatives was developed. Free guanidine reacted with Cbz-protected aminoglyeosides to produce guanidinylearbonyl substituted derivatives. A methoxycarbonyl-protected intermediate was isolated, and the mechanism of guanidinylcarbonyl modification was proposed. With this method, six per- or part- guanidylcarbonyl substituted aminoglycosides were successfully obtained in good yields. Their in vitro antibacterial activities were essayed.
