Retroreflector array is used as pseudo phase conjugator in the system. The fidelity of the conjugate wave and matching problem of the retroreflector array and Hartmann-Shack wavefront sensor is discussed. Several data fusion methods are presented in order to having two Hartmann-Shack wavefront sensors control one set of wavefront corrector. The misalignment errors of Hartmann-Shack wavefront sensor and arrangement errors of wavefront sensor and deformable mirror are analyzed.

With the deepgoing of the market economy and the lifting of people's life quality, there are higher and higher demands of real estates. The value of real estates is not only for living but also for exchange. The system of commodity estate forward-sale has been established in China, but we didn't pay much attention to the legal issues of this system and the laws on this system are not enough in our legal system, for example, the character of the commodity estate forward-sale contract, the rights and obligations involved in the contract, the forenotice registration system ,the transfer of the forward-sale contract and ect.

Thus gp130 is the common signal transduction molecule. Gp130 molecule expresses universally on many tissues including immune system, hemapoietic system, and nerve system. Gp130 has an essential role in the function and regulation of the above systems, especially in the development of hemapoietic system. The signal transduced by gp130 is necessary during the differentiation and proliferation of hemapoietic cells. It is evidenced that the embryo of gp130 gene-knockout mouse was dead due to a serious impediment of the development of hemapoietic system.

Gp130在人体组织细胞上广泛性表达，介导和调节机体的免疫、造血以及神经系统的生理功能，尤其是在造血系统的发育过程中，具有极其重要的作用，动物实验表明，敲除小鼠的gp130分子基因可以使其在胚胎的早期阶段产生严重的造血系统障碍，最终导致流产，由此表明在造血细胞的分化、发育和生物学行为中，gp130介导的信号是必不可少的。
