The results of the dissertation were concluded as follows:(1) It is essential to deposit a basic additive on the Mo-based catalysts for the synthesis of CH_3SH. The potassium-doped Mo-based catalysts exhibit the highest activity than that of the catalysts doped with the otherⅠA andⅡA group basic promoters. H_2-TPR and LRS characterizations suggest that the addition of a base leads to the transformation of octahedrally coordinated Mo to tetrahedrally coordinated Mo, thus leads to the split of low temperature reduction peaks. The interaction between the basic components and Mo lead to the formation of B-Mo interface phase, which are closely correlated with the formation of CH_3SH.(2) It has been found that Fe, Co, Ni and Te have evident promoting effects for the K-Mo/SiO_2 catalysts.
主要结果归纳如下:(1)在Mo基催化剂中,必须添加碱才具有可观的合成甲硫醇活性,在IA和IIA族元素中,K是最佳的碱促进剂,当K/Mo摩尔比为2,前驱体为K_2CO_3,采用共浸法制备的K-Mo催化剂活性最高。H_2-TPR和LRS表征显示,碱的加入导致表面八面体钼氧物种向四面体转化,催化剂的低温还原峰发生分裂,碱助剂与钼之间存在强相互作用形成了B-Mo"界面相",该物种与合成甲硫醇密切相关。

The mature egg cell was an inactive cell with only a few polysomes. At the early zygote stage, a large number of ribosomal precursors were produced by the nucleolus, and many polysomes appeared in the cytoplasm, which suggests a high level of metabolism. Zygote at the dormancy stage had a small nucleolus and marked decrease in ribosomes, as shown by a few polysomes, which suggests decreased metabolism. Zygotes in the prophase of mitosis and two-celled proembryo became active again in metabolism, for a prominent nucleolus, high density of ribosomes and increased number of polysomes in the cytoplasm.

A novel polymer of Poly(diglycidyl maleate-co-stearyl methacrylate) was synthesized and its structure was characterized by ~1H NMR. Its self-assembly behavior was studied in different solvents. It was found that vesicles and tubule-liked aggregates can be obtained through self-assembly of P(DGMA-co-SMA)/THF/EtOH system. And spheral aggregates were obtained in P(DGMA-co-SMA)/THF/H_2O system while the spheral aggregates were converted into rod-liked aggregates and line-liked aggregates after aged for different time.

In crystal, two APC-PY trimers associate into a hexamer by face. The assembly of two trimers within this hexamer is very similar to that of C-phycocyanin and R-phycoerythrin hexamers, but the tight level of the assembly of two trimers within this hexamer is clearly not so much as that of C-PC and R-PE hexamers.

These results reveal that the APC〓 trimers in the core cylinders of phycobilisomes favour a standard face to face manner to associate into a〓 hexamer, but probably, the APC〓 trimers cannot form a stable〓 hexamer like C-PC and R-PE hexamers due to the relatively weaker association between two trimers, but a relatively looser hexamer.
这些结果表明位于藻胆体core cylinder中的APC〓三聚体趋向于以通常的面对面的方式缔合成〓六聚体,但由于六聚体内两个三聚体之间的相对较弱的相互作用,APC三聚体很可能不能形成象C-藻兰和R-藻红一样的稳定的六聚体,而只能形成一个相对松弛的六聚体。

After the inputs of image penetrated the CMOS Sensor to receive the data of the image makes the RGB form the transformation. The CPU processes operation of image detects. After the processed of image deliveres to VGA displayed output of real-time image. We use example programs of DE2 platfrom to achieve entire hardware on experiment board of SOPC-NIOSII EDA / SOPC System platform. On system of dectect image we divided into two parts : hardware and software. We use Verrilog of HDL to modify code in hardware. To use Custom IP of SOPC Builder produced IP of our need.

S the computation power and the memory capacity increase, the corpus-base speech synthesis system has become the best and most popular speech synthesis system. Based on the system, the linguistic features are first derived after the text is parsed, then some appropriate units are selected as candidates. Finally, the well-pronounced speech is synthesized by concatenating the best unit sequence by the synthesizer part of system.
