With the aid of a Pyrolysis-GC/TOF MS technique, the pyrolysis behaviour of two menthyl esters of N-benzoxycarbonyl amino acid was investigated. A clear pattern emerges involving the cleavage of the bond linking the menthyl ring to the carboxy group, followed by further degradation of the fragments. The major pyroproducts were p-menth-l-ene pyrolysed at a higher temperature or p-menth-2-ene pyrolysed at a lower temperature, and various derivatives of cyclohexene pyrolyzed from the menthyl ring. In addition, some of the products were also iden- tified as derivatives of benzene from the pyrolysis of benzyloxyl moiety.

AlGaAs光电阴极具有响应速度快和光谱响应范围可调的特性,可被应用于水下光通信领域.为了解决AlGaAs发射层较低的光吸收限制其量子效率提高的问题,利用分布式布拉格反射镜(DBR)结构对特定波长光的反射作用,将透过光重新反射回发射层进一步提高吸收率,从而增强阴极在532 nm波长处的响应能力.通过求解一维连续性方程,建立了具有DBR结构的AlGaAs光电阴极光谱响应模型.采用时域有限差分法,分析了DBR结构中子层周期对数、子层材料以及发射层、缓冲层厚度对发射层吸收率的影响,对比了有无DBR结构AlGaAs光电阴极的光吸收分布.结果表明,周期对数为20、子层材料为Al_(0.7)Ga_(0.3)As/AlAs的DBR结构对532 nm光的反射效果最优.基于该DBR结构,发射层和缓冲层厚度分别为495 nm和50 nm时,发射层对532 nm光具有最佳吸收率.通过对外延生长的AlGaAs光电阴极进行激活实验,结果表明具有DBR结构的AlGaAs光电阴极在532 nm波长处的光谱响应率相比无DBR结构的AlGaAs光电阴极光谱响应率提升了约1倍.

The New Vacuum Solar Telescope （NVST） is a one meter vacuum solar telescope that aims to observe fine structures on the Sun. The main goals of NVST are high resolution imaging and spectral observations, including measurements of the solar magnetic field. NVST is the primary ground-based facility used by the Chinese solar research community in this solar cycle. It is located by Fuxian Lake in southwest China, where the seeing is good enough to perform high resolution observations. We first introduce the general conditions at the Fuxian Solar Observatory and the primary science cases of NVST. Then, the basic structures of this telescope and instruments are described in detail. Finally, some typical high resolution data of the solar photosphere and chromosphere are also shown.
