The performances of devices degrade notably when the irradiation dose is larger than these thresholds.(3) The electron-hole pairs in oxides and interface states on Si/SiO〓 induced by radiation, which also can lead the voltage drift of control transistor in pixels, were the chief reason that leads the increase of dark current density in pixels.

3分析认为：辐照在像素的氧化层中诱发的电子—空穴对和Si/SiO〓界面形成的界面态使像素暗电流密度增加；同时也导致转移晶体管的阈值电压漂移，这是造成器件性能退化的主要原因。

For example, alkaline elements can affect diffusion velocity of Zr, Si and O ions although these alkaline elements cannot exist in crystal structure of zircon. However, K rich media and Na rich media exert different effects on the growth of crystal form: in the K rich media, growth speed of prism faces in the vertical direction is much higher than that of pyramid faces, and {111} growth speed in the vertical direction is higher than {311},which decides the formation of bipyramids dominated by {311} pyramids; in the Na rich media, both prism and pyramid grow to a certain extent, but the former is smaller than the latter.{100} growth speed in the vertical direction is lower than {110}, while {111} growth velocity in the vertical diredtion is lower than that of {311},resulting in the growth of the crystal form characterized by {100} short prism and {111} pyramid.

例如，尽管碱性元素并不进入锆石晶格，但它们可以影响Zr、Si、O离子的扩散速度，但是富钾和富钠的介质对锆石晶形发育的影响是有差别的，表现为：在富钾的介质中，将导致柱面的法向生长速度较锥面快得多，而锥面中，｛111｝的法向生长又较｛311｝快，由此决定了形成以｛311｝锥为主的双锥状晶体；在富钠的介质中，柱面和锥面都有一定程度的发育，但前者弱于后者，而柱面中，｛100｝的法向生长较｛110｝慢，由此决定了形成以｛100｝柱和｛111｝锥为主的短柱锥状晶体。

The results show that the maximum detectivities of a-Si and polySiGe bolometers are 2.23×108 and 3.75×108 cmHz1/2W-1 respectively, and TFT-based room-temperature infrared detectors have a maximum detectivity of 1.02×109cmHz1/2W-1, which reaches the same highest level in performances in the world.

结果表明，斩波频率为30Hz时，a-Si和polySiGe测辐射热计的最高探测率分别达到2.23×108和3.75×108cmHz1/2W-1，TFT室温红外探测器的最高探测率可达1.02×109 cmHz1/2W-1，达到目前国际先进水平。

Ni-Cr-B-Si alloy powder with adding rare earth was cladded by CO2 laser on the surface of 45 steel, then Ni-based coating which is combined in metallurgy with the matrix and has good performance was obtained.

为提高零件表面的耐磨性和耐蚀性，采用CO2激光器在45钢表面熔覆添加稀土的Ni-Cr-B-Si合金粉末，获得了与基体呈冶金结合的、性能良好的镍基涂层。

The results show that with the increasing of excess Si content in the alloys, the size of the secondary phasse precipitates is decreased and the distribution is densified.

原因在于过剩硅的存在降低了第二沉淀相中的Mg／Si比率，增加了β沉淀相粒子的数量，从而使时效强化作用得到加强。
