定向诱导基因组局部突变技术(Targeting Induced Local Lesions IN Genomes,简称TILLINC)是一种全新的、高通量和低成本反向遗传学研究方法。近年来,随着突变筛选技术的革新,TILLING技术平台日趋多元化,使得TILLING技术的操作更为简单、快速,并广泛应用于作物育种研究领域。简要介绍了TILLING技术平台的最新发展动态,并初步探讨了将辐射诱变处理与TILLING高通量筛选相结合在诱变育种中的应用前景。
The CR superconducting magnet is a dipole of the FAIR project of GSI in Germany.The quench of the strand is simulated using FEM software ANSYS.From the simulation,the quench propagation can be visualized. Programming with APDL,the value of propagation velocity of normal zone is calculated.Also the voltage increasing over time of the strand is computed and pictured.Furthermore,the Minimum Propagation Zone(MPZ)is studied. At last,the relation between the current and the propagation velocity of normal zone,and the influence of initial temperature on quench propagation are studied.
High homogeneity of the CR (collector ring) dipole magnet for FAIR (Facility for Antiproton and Ion Research) project at GSI is essential.The two optimized and analysis methods are introduced in detail,In order to obtain an ideal integral magnetic field distribution,the complicated end chamfer has been designed.By chamfering the removable pole,the distribution tolerance of high magnetic field is optimized to±2×10^(-4).The method of adding a mirror plane is suitable for the high magnetic field and it doesn't fit the low one.The OPERA is used to optimize the dipole magnetic field.
