Second systematic perceptual bias could impair the validity of self-reports (Canary et al. 1995) such as the fundamental attribution error Sillar 1985 cited in Canary et al.

第二，系统的知觉偏差可能削弱自我报告的有效性（Canary et al。，1995年），如，基本原则归属错误（Sillar，1985年引用Canary et al。，1995年）。

For each specified amount of titanium tetraiodide used, there is a "critical Al/Ti ratio" at which the catalytic system displays highest activity, below which it shows no activity, and above which its activity decreases gradually Fig.

对每一四碘化钛用量出现一具有最高活性的&临界Al/Ti此&；低于这一Al/Ti比，活性完全消失；高于这一Al/Ti比则活性逐渐降低(图2)。

For the effect of surface oxidation on emissivity:(1) most oxidized samples have higher emissivity than unoxidized samples, except AL 2024 and AL 7005. The exception is due to roughened surface caused by the onset of melt and the change of surface color at high heating temperature.

铝合金有氧化与无氧化对放射率的影响：(1)大部份铝合金有氧化的放射率皆大於无氧化的放射率，除了AL 2024与AL 7005，因为熔化造成表面粗糙度增加及高温加热时表面色泽的改变导致无氧化的放射率大於有氧化的放射率。

对高能球磨制备的Cu--Al预合金粉末中Al内氧化的工艺进行了研究。

He sintering of Ti/Al -Al_2O_3 powder in nm scale on SPS is composed of those moments: originally pressing period, exhausting and intenerated period, Al's consumption period,Al_2Ti's creation period, the main alloying and consolidation period and homogenization period.

i/Al-Al_2O_3系纳米级别的粉体在SPS上的烧结过程中，主要分为初始加压阶段、排气与软化阶段、Al消耗阶段、Al_2Ti生成阶段、主要合金反应与烧结阶段和均匀化阶段。

The results show: TiC particulates can act as nucleates of α-Al and enter into α-Al during solidification. They also can act as nucleates of S' phase during ageing, there are a lot dislocations around TiC particalates, which accelerate ageing process of 2024/TiC composites.

研究表明：TiC颗粒能作为α—Al形核核心，在凝固过程中进入α—Al基体；在时效过程中，TiC颗粒可以作为S′相的衬底，其周围存在大量位错，加快了复合材料的时效进程。

The results show that the dissolution process of prefabricating alloy can be divided into two periods when the temperature of zinc melt is below the melting point of aluminum.Firstly,zinc melts infiltrates into the prefabricating alloy and then Zn-Al-TiC alloy forms in the surface layer of the prefabricating alloy.Secondly,the Zn-Al-TiC alloy of this alloy surface layer begins to dissolve to the zinc melt.

结果表明：当锌熔体温度低于铝熔点时，预制合金的溶解可分为两个阶段：第一阶段为液态锌向预制合金中浸渗，并在预制合金表层内形成Zn-Al-TiC合金；第二阶段为预制合金表层内的Zn-Al-TiC合金开始溶解并进入锌熔体。

The simulated results show that the AO exposures strongly affect the microstructures and properties of the two film materials. For instance, as the AO exposure increases, the mass loss increases, the surfaces of the two types of films roughens, the optical transmittance of Kapton and reflectivity of Kapton/Al mirror degrade, but the solar absorptance of kapton/Al films increases.

结果表明：两种材料的质量损失随原子氧暴露剂量的增加呈线性增大；原子氧暴露后，试样表面呈&地毯&状形貌，且随暴露剂量的增加粗糙度变大；Kapton薄膜的光谱透过率、Kapton/Al薄膜二次表面镜的光谱反射率随原子氧暴露剂量的增加而降低，Kapton/Al薄膜二次表面镜的太阳吸收比Δα随暴露剂量的增加而增大。

In addition, laser Raman scattering and low temperature photoluminescence measurements are carried out, the GaSb-like LO mode, AlSb-like LO mode and the coupled mode between LO phonon and plasmon are observed. According to the dependence of the GaSb-like LO mode frequency on Al composition, an empirical formula was obtained for determining the Al composition.

用激光喇曼散射和低温光致发光研究了材料的光学性质，观察到了类GaSb的LO模和类AlSb的LO模以及LO声子与等离子体激元的耦合模L，并根据类GaSb的LO模随Al组分x的变化规律，得到一个计算Al组分的近似公式。
