SONY Cyber-shot DSC-T2

数码相机的普及造就了年轻一代的“即拍文化”，索尼T2就是针对这一族群而推出的产品。为了吻合年轻新生代对色彩的喜好，索尼为T2设计了5款个性化绚丽机身本色白、炫酷黑、动感蓝．灵动绿和魅力粉。有些朋友可能会发现，此次索尼T2所提供的5种色彩比起以前索尼T系列产品高贵的银色和沉稳的深红深黑色，更加倾向于年轻人的简约和时尚路线。更加年轻多彩，这就是T2的风格。

爱她 就拍拍她——娜娜、洋洋和她们的EOS 500D

娜娜,与所有白领一样,日复一日地在钢筋水泥丛林中,为自己的生活坚强地奋斗着。每天傍晚,当拖着疲惫的身躯回到家中,一只漂亮地金毛“狗小姐”就会热情洋溢地扑过来,围着她亲昵地蹭着。     

Synthesis, Characterization and Properties of Tri-substitute Potassium Salt of Trinitrophloroglucinol

The title complex [K3（TNPG）·（H2O）2]n was synthesized by the reaction of the aqueous solutions of trinitrophlomglucinol （TNPG） with KHCO3. The complex was characterized by elemental analysis and FTIR spectroscopy, and its single crystal structure was determined by X-ray diffraction analysis. The structural analysis demonstrates that two different coordination modes of K cations [K（1） and K（2）] are around TNPG^3- anions in complex [Ka（TNPG）·（H2O）2]n, where the coordination numbers are eight. All K atoms coordinate with O atoms of phenolic hydroxyl group and nitro-group simultaneously. The thermolysis of the [Ka（TNPG） · （H2O）2]n has been investigated by using differential scanning calorimetry （DSC） and thermogravimetry-derivative thermogravimetry （TG-DTG） at a heating rate of 10 ℃/min. The thermal decomposition processes of the title complex were comprised of one endothermic dehydration stage and one exothermic decomposition stage in 270-320℃, and the final decomposition residue contained KNC. Impact and friction sensitivity results of the complex revealed its sensitive nature towards mechanical stimuli. The experiments verified that the complex has some characteristics of explosive.

Strain Rate Sensitivities of Face-Centred-Cubic Metals Using Molecular Dynamics Simulation

We use dislocation theory and molecular dynamics （MD） simulations to investigate the effect of atom properties on the macroscopic strain rate sensitivity of f cc metals. A method to analyse such effect is proposed. The stress dependence of dislocation velocity is identified as the key of such study and is obtained via 2-D MD simulations on the motion of an individual dislocation in an fcc metal. Combining the simulation results with Orowan＇s relationship, it is concluded that strain rate sensitivities of fcc metals are mainly dependent on their atomic mass rather than the interatomic potential. The order of strain rate sensitivities of five fcc metals obtained by analysing is consistent with the experimental results available.
