At last, By using the factorization properties of cyclotomic polynmials on finite fields and the construction characteristic of cyclic codes, we present the relation of the period distribution of cyclic codes and the period distribution of their dual codes, establish the explicit formula for the number of the codewords without inner-period of the cyclic codes and their dual codes, find the method for computing the dimension and the period distribution of narrow-sense primitive BCH codes,and study the inverse question of period distribution of cyclic codes.

最后，利用有限域上分圆多项式的分解特性和循环码的构造特点，揭示了循环码的周期分布与其对偶码周期分布之间的内在联系，确定了一般循环码及其对偶码内无内周期码字的精确计数公式，决定了狭义本原BCH码的维数与周期分布，讨论了循环码周期分布的反问题。

So, the radiation backgrounds of DAMA set-up have been studied in the thesis, and the simulated values are in coincidence with the ones of DAMA experiments.

为此，我对DAMA实验的本底问题进行了模拟研究，在低能区获得了同DAMA实验本底计数相符的结果。

However, the molecular mechanisms underlying premature aging up 8-MOP/UVA are as yet unknown. In our studies, dermis of the non-lesion back skin of vulgar psoriatic patients who had been treated by PUVA and the cultured foetus dermic fibroblasts were selected to be observed.

本课题以PUVA治疗寻常型银屑病患者背部非皮损区真皮及培养的胎儿真皮成纤维细胞为对象，采用HE染色、Verhoeff染色、电镜、酶组织化学、免疫组织化学、原位杂交、流式细胞计数仪、三引物PCR、PCR-SSCP技术及PCR产物直接测序等技术和方法，研究了8-MOP/UVA对皮肤光老化形成的影响及芳维A酸乙酯的拮抗作用。

By phenotype observation, combined with root tipchromosome counting, PMC MI pairing analysis and chromosome C-banding, a ditelosomic addition line 94K227 and a disomic addition line 94K280 was identified among BC2F2 and BC2F3 population respectively.C-banding results showed that 94K227 contains 1 pair of long arms in chromosome B, and 94K280 contains 1 pair of chromosome D from R.

用普通小麦-纤毛鹅观草双倍体与普通小麦中国春连续回交两次，然后连续自交，通过形态观察、根尖细胞染色体计数、花粉母细胞减数分裂中期Ⅰ染色体配对分析及染色体C－分带，在BC2F3和BC2F3群体中，分别筛选到一个端二体异附加系94K227和一个二体异附加系94K280，其中C-分带显示94K227添加的是纤毛鹅观草染色体B的一对长臂， 94K280添加的是纤毛鹅观草的一对染色体D。

Objectives A rat model sciatic nerve crush injury was reproduced in rat, and behavioral changes, pain threshold, thermal withdrawal latency and the changes in c-fos expression in cornu dorsale medullae spinalis were examined, and the relationship between peripheral nerve regeneration and hyperpathia was explored.

目的 建立大鼠坐骨神经挤压模型，观察其神经恢复过程中行为学、机械痛阈值、热缩足反射潜伏期以及脊髓背角c-fos表达（对c-fos表达产物：Fos蛋白阳性的神经元进行计数）的改变，探讨外周神经损伤再生与痛觉过敏的关系。

Our within-subject analysis also showed activation of brain areas associated with negative emotions, including right insula and putamen (11, 38), during the high-stress relative to the low-stress task. The observed activation in the dorsomedial prefrontal cortex ACC and precuneus parietal cortex may ref lect mental arithmetical performance (39) and assessment of the mental state (40) during the serial-subtraction task, whereas the CBF reduction in pre- and postcentral gyri and temporal cortex may ref lect more frequent verbal movement and greater auditory stimulation during counting backward versus serial subtraction.

我们的在之内主题分析也显示了脑子区域的活化作用与消极情感相关，包括正确的脑岛并且putamen (11， 38)，在期间高注重相对低注重任务在连续减法任务期间，被观察的活化作用在dorsomedial前头叶外皮ACC和precuneus头顶骨外皮可以ref lect精神算术对精神状态(40)的表现(39)和评估，而CBF减少前和中央后回和世俗外皮可以ref lect更加频繁的口头运动和更加伟大的听觉刺激在计数期间落后对连续减法。

In the count-down to Drupa, exhibitors began previewing plans in January.

在计数下降到德鲁巴，参展商开始预览计划在1月。

The American Ginseng ,as the study objects, which grew in different years in Jiling and Beijing, were studied on Dynamics of Soil Microorganisms by separating, culturing, counting and identifying the edaphon among soil of American Ginsengs.

以吉林、北京两个产地不同年限西洋参根际土壤微生物为研究对象，对其土壤微生物进行分离、培养、计数和鉴定来研究土壤微生物区系的动态变化。

When the count-down timer for cooling reaches 0 the entire electrofusion process is completed.

待冷却时间倒计数为零时，整个熔接过程结束，关机并拔下连接插头。

The fusion of donor-recipient pairs was induced with different parameters for electrofusion with variation in electric field intensity, pulse duratio...

在不同电融合条件下诱导两者间的融合，并对重组胚激活以及随后发育的早期阶段包括2细胞、4~8细胞和桑椹胚进行观察和计数。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
