The type, initial feeding time and concentration of precursor for HV unit formation had great effects on PHBV production in shake flasks. Propionate was selected as the better precursor for HV fraction than valerate after comprehensive survey of these two precursors. The suitable PHBV shaking-flask culture conditions were obtained through the analysis of PHBV fermentation process, the investigation of several factors by using RSA method and the fed-batch experiments. Cell dry weight, PHBV content, PHBV concentration, HV fraction and yield coefficient of HV unit to propionate were 27. 7g/L, 80.7%, 22. 4g/L, 16. 1mol% and 0.50g/g, respectively.

在共聚物PHBV的摇瓶发酵过程中，PHBV中HV组分形成的前体物质的种类、初始加入时间以及加入量是影响PHBV发酵过程的重要因素；在综合比较丙酸和戊酸这两种前体的基础上，选择丙酸作为HV组分合成前体较适宜；通过对PHBV发酵过程曲线分析、影响PHBV发酵指标的各因素的响应面分析以及摇瓶发酵补料试验，得到了较适宜的PHBV摇瓶发酵补料条件，在此条件下，细胞干重、PHBV含量、PHBV浓度、HV组分含量和HV组分对丙酸的产率系数可分别达到27.7g/L、80.7％、22.4g/L、16.1mo1％和

Just under this background, studying on the flight mechanism of flapping-wing MAV and sample fabrication from the bionics are conducted in this dissertation. The kinematics equations of insect wings can be acquired by the observation and measurement on the natural insect in researching paper. The geometry model of insect is established by UG technology. The three dimensional grid during the insect moving in the flow field is achieved which adopted grid generation method. The characteristic of lift and drag are attained by simulation the surround flow field during the locomotion of wings, and the flight mechanism of insect is discussed. Based on this study, the physical flapping-wing MAV is fabricated by the acquirable materials and parts of apparatus in existence.

正是在这一背景下，本文从仿生的角度来研究微型飞行器的飞行机理与样机制作；通过查阅文献中对自然界中昆虫翅膀运动的观察与测量，获取了昆虫翅膀的运动方程；采用UG建模技术，建立昆虫的几何模型；采用网格划分方法，获取昆虫在流场运动时的三维网格；运用CFD方法模拟翅膀运动时周围的流场，获取昆虫运动时的升阻力特性，进而来研究昆虫的飞行机理；在此基础上，通过现有可用的材料加工制作仿生微型飞行器。

In fish and amphibia, the transition from maternal gene transcription to zygotic transcription happens during the time of midblastula formation, this stage is named by midblastula transition, at this period, embryo cell cycle composition changes, it is the first time to G1 time appearance, the cell cycle timelimit lengthens and the cell division synchronism loses, the large quantities of zygotic gene transcription starts.

鱼类和两栖类由母型调控向合子型调控过渡发生在中囊胚形成阶段，称为中囊胚过渡(midblastula transition，MBT)，胚胎细胞周期时相的组成在此期间发生变化，首次出现G1期，周期时限延长，细胞分裂的同步性丧失，大批合子型基因活化转录也在此时开始。

In this Buddha Land, he would receive those followers who faithfully chanted the nembutsu (known in Sanskrit as narno amitabha- buddhaya and in Japanese as namu amida butsu and in Chinese as namo amitofo), a petition to the Amitabha Buddha, of whom Dharmakara would be the first incarnation, for salvation and rebirth into his Buddha Land, known as the Pure Land.

在此佛土，他将接引一切至心虔诚的念佛(梵语中的&南无阿弥塔巴佛陀耶&。口语中的&南莫阿弥达补至&，汉语中的&南无阿弥陀佛&)者，一切向阿弥陀佛祈愿的人。法藏比丘将是阿弥陀佛土的第一个化生者。他为救度世人而再生于彼的国土就称作净土。

According to the calculation of the relative contributiveness rate of elements and its attributes,the relative position and cause of formation of every element in system are analyzed,and the main elements are determined.

在此基础上，计算系统内各要素及其属性的系统贡献度，并以此为依据分析各要素在系统中所处地位及成因，确立了城市产业竞争力和城市政府管理力在UCS中的核心影响要素地位。

After the success of this album, it didn't take long for the prolific young artist to bounce back the following summer with his solo album, Unleash the Dragon. The album's hit singles propelled it to multi-platinum success, setting the stage for Sisqó's forays into acting. He first appeared in the teen comedy Get Over It, before signing a development deal with NBC television and a five-picture deal with Miramax.收藏 Prong -《Power of the Damager

在这张专辑获得巨大成功之后，这位多产的年青艺术家没有花多长的时间就凭借接99年夏天单飞后推出的首张专辑&Unleash the Dragon&迅速上位，这张专辑中的多首打榜单曲使得专辑获得了多白金的销量成绩，Sisqó的事业也成功的拓展到了表演方面，他的第一次露面是在青少年喜剧&Get Over It&中，不过在此之前，他已经跟NBC电视台签约并且和米拉麦克斯签了五部电影的合约。

Polymorphic type system with constraints in Garment is studied in this paper including type checking algorithm. It is proved that the satisfiability of constraints in the algorithm is decidable.

A total of 21 isolates of soil dematiaceous hyphomycetes belonging to 15 species in 11 genera were obtained from 20 soil samples from Changtang Steppe in northern Tibet. Among them, Phialophora tibetensis is a new species; Phialophora melinii and Scopulariopsis fusca are new records for China.

作为对青藏高原土壤中暗色丝孢菌属、种多样性系统调研的一部分，笔者从采自藏北羌塘草原的20份土样中，分离获得21个暗色丝孢菌分离物，经鉴定分别属于11属中的15种，其中包括1个新种，西藏瓶霉Phialophora tibetensis和2个中国新记录种：蜜色瓶霉Phialophora melinii和暗色帚霉Scopulariopsis fusca，多数种为在此区域首次发现。

But there are many problems when they are trying to use the model theories. The main problem is that the soul of the theories could not be understood in right way and it is always to be executed in inflexible way. This problem is elementarily discussed in this article.

在此过程中出现了许多这样那样的问题，主要表现在对国外的现代理论理解上的不到位，以及在与企业具体实践相结合的过程中缺乏灵活性所致，本文对此进行了初步的讨论。
