It is well known that the large lattice mismatch (16%) and thermal expansion coefficient mismatch between GaN and sapphire substrate are the main origins of TDs. By new growing technique of LEO, we acquired high quality GaN films almost free of TDs. The stress characteristics in GaN films with MLTB growing technique is dependent on growing systems and conditions, and the changes of stress and dislocation density are rightabout; Combining buffer layers of high temperature and low temperature is first developed to growing GaN films with low dislocation density, and the mechanism of lowering TDs density is that the first buffer layer of high temperature can make nuclear in second buffer layer of low temperature bigger. This technique also can restrain yellow luminescence effectively.

众所周知，晶格失配和热应力失配是GaN异质外延中位错产生的主要原因；为此，我们对几种降低缺陷的MOCVD外延生长方法进行了新的尝试，其中尝试了侧向外延生长技术，得到了低位错密度（小于10〓/cm〓）、高质量的GaN外延层；尝试多低温缓冲层法，发现材料中的应力特性与生长系统和生长条件有关，材料中的应力与位错密度按相反方向变化；首次尝试高低温联合缓冲层法，材料中高温缓冲层可以使随后的低温缓冲层中成核颗粒增大，从而导致随后高温GaN外延膜中位错密度降低，并且能够有效地抑制黄光峰。

The low-temperature resistivity of filling skutterudite increases with the increase of temperature. However the slope of the resistivitytemperature curves are different. The curve of the sample with low filling fraction is smooth, and that of the samples with high filling fraction is sharp. It is caused by the existence of the impurities in the samples with low filling fraction.

填充型方钴矿材料的低温电阻率随镧填充率的变化规律与室温相同，但不同填充率的方钴矿材料的电阻率随温度变化的曲线的斜率不同，低填充率样品随温度变化趋势明显地比高填充率样品平缓，这种现象主要是由存在于低填充率样品中的杂质相引起的。

Results In 11 cases,5 cases were intracranial,and 6 cases intravertebral canal.MRI could effectively show similarly shuttle or long-round shape's abnormal signal imaging.The T1W imaging showed uniformity or asymmetric and low or equal signal.The borders were slighty low or equal signal intensity,some had spetum.The T2W imaging showed obviously high signal,and a few cases showed slightly high or equal signal,while the borders showed slightly low or equal signal imaging.The thin peripheral could be obviously enhanced,but without inner enhancement.

Through a series of quenching, tempering, tensile testing, low-temperature impact test and metallographic analysis, we ultimately came to the following conclusions:(1) low-carbon alloyed steel 20CrMn2NiMoV quenching at 870℃ and tempering at 200℃, whose structure contains tempered dislocation lath martensite and few small bainite under mixed, has the best obdurability;(2) Carbon Steel 45CrMn2NiMoV quenching at 850℃ and tempering at 620℃, whose structure is sorbitic, has a performance less than that of low-carbon Alloyed steel, but it can also meet the basic design requirements.(3) Mn can substitute for the role of Ni within limited extent.
