For cloning antifreeze protein gene from a desert darkling beetle Microdera punctipenis dzunarica in Xinjiang, the primers were designed according to the core sequence of AFP gene deposited in GenBank, and the cDNA fragment about 294 bp named as MpAFP5 was amplified with the RT-PCR and 3'-RACE technique. Sequence analysis revealed that the cloned cDNA fragment named as MpAFP5 coded the mature peptide of AFP.

根据GenBank中已发表的昆虫抗冻蛋白基因的保守序列设计引物，利用RT-PCR技术结合3'-RACE扩增的方法，从新疆荒漠昆虫准噶尔小胸鳖甲Microdera punctipenis dzunarica中获得了长约294 bp不含信号肽的抗冻蛋白cDNA片段，命名为MpAFP5，其全长序列为363 bp(GenBank注册号为：AY821792)。

For example, we cannot copy an unknown state exactly because of "the no-cloning theorem"(no-deleting theorem), which is known as one of the most significant differences between classical and quantum information. Therefore to get to know what we can and cannot do in QIS or in quantum physics becomes an important and interesting problem. Particularly, in quantum communication and quantum cryptography, many novel schemes are based on the fact that nonorthogonal states cannot be discriminated determinately.

例如，经典信息中，编码状态是可以精确复制、区分的；而在量子信息中，由于叠加性的存在，使得非正交态不可区分，量子态不可复制、删除等；故而以往既成的观念都被打破，探讨在量子信息的框架下编码信息的估计、物理可实现的操作，以及这些量子体系在外界通过物理方法进行识别过程中的差异，是量子信息学、乃至物理学中的重要也很基本的问题。

Now the research on HPL focus on dicotyledon, and the research on HPL of monocotyledon still havent been reported. In this paper, the research on cloning of rice HPL and enzyme activity assay were carried out and several result were obtained.1. Enzyme activity assay of rice HPLBased on the method of measure HPL Enzyme activity in other plants, the means on preparation of hydroperoxides and measurement rice HPL activity were set up. The 9-HPL arid 13-HPL activity of several rice varieties with different storability and different dormancy were tested.
