During the process of long-time adaptive evolution, wetland plants adopted a series of special strategies to acclimate to salt stress. The main strategies are: 1 life history adjustment, e. g., to adjust seed germination time, implement seed dormancy and viviparity, and change reproductive manner to escape from direct salt stress, 2 morphological adjustment, e. g., to adjust biomass allocation pattern, age stem, defoliate, and carnify vegetative organs to isolate the redundant Na(superscript +) to the inactive-metabolism shoots or exclude the Na(superscript +)from tissues; 3 anatomic adjustment, e. g., to sink stoma, develop aerenchyma, and thicken cuticle and phellogen to maintain normal photosynthesis and respiration; 4 physiological and biochemical adjustment, e. g., to exclude and excrete salt, compartmentalize ions, adjust osmosis, do selective absorption, regulate hormones, and induce antioxidative enzymes to maintain the osmotic equilibrium and eliminate the active oxygen in cell; and 5 molecular level adjustment, e. g., to start up many salt-induced genes to regulate the metabolic responses to salt stress.
在长期的适应进化过程中,湿地植物形成了多种适应盐胁迫的策略,主要有:1生活史方面,植物可通过种子萌发时间的调整、种子体眠、胎生、繁殖方式的改变等逃避盐度的直接伤害;2形态学方面,植物可通过生物量分配模式的调整、茎的老化、落叶及营养器官的肉质化等将多余的Na隔离到代谢不活跃的茎中或将其排出体外;3解剖学方面,植物可通过气孔下陷、发达的通气组织、增加细胞木栓层、角质层及栅栏组织的厚度等以维持植物正常的光合作用和呼吸作用;4生理生化方面,植物可通过离子区隔化、拒盐、泌盐、选择性吸收、渗透调节、激素调节及抗氧化物酶的诱导等来维持细胞内正常的渗透压,清除胞内活性氧分子;5分子水平方面,植物可通过多种与盐胁迫相关的基因来调控细胞内的多种代谢反应。

Chapter 5 deals with the solvable theorem of adaptive inverse optimal control problems for a class of stochastic nonlinear systems driven by Wiener noises of unknown covariance. The systems are depicted by It〓 stochastic differential equations. By using an adaptive backstepping algorithm and stochastic control Lyapunov functions, the designing procedure of control laws of global asymptotic stability in probability and adaptive inverse optimal stabilization in probability are presented systematically.

In our thesis, contents are organized as following In Chapter 1 we present our topic's internal and overseas research situations, theoretical and practical significance, and introduce the research object and contents, and the main contributions of this dissertation. Chapter 2 reviews the development of the stability results for nonlinear systems and some relevant recent results, which include Lyapunov and LaSalle-Yoshizawa theorems for nonlinear systems, and stochastic edition for stochastic nonlinear systems. Sontag's formula for systems affine in control is presented in the frame of CLF. The concepts of disturbance attenuation and the inverse optimality are also explained in this Chapter. In chapter 3 we present the solvable theorem of inverse optimal gain assignment problem, design the inverse optimal controller and the inverse optimal tracking controller for strict-feedback nonlinear continuous systems with unknown time-varing bounded disturbances and constant unknown parameters using an adaptive backstepping algorithm, which are nonlinear, continuous and are easier to realize. These designs are fully systematic and the algorithm can be directly coded in symbolic software. The results of simulation show the effectiveness of the control algorithms.

It can adjust convergence constant automatically, it can also be recurred with real gradient value. Thus the field to apply the adaptive filter is widened, the convergence speed of the adaptive filter is sped up, the weighted disadjustmend is decreased, so that the last error of mean square approaches its minimum value more.

This paper therefore examines the development of "the folklore Pai-Chang of Peking opera aria in Tainan city" through literature review depth-interview oral history and participant observation The concept frame is culture organism as the vertical axle and elements of a folklore activity as the transverse axle There are several significant findings about the general picture of this subject: During the late period of Japanese colonial era Tainan local people who played Peguan music learned Peking opera aria and tried to bring Peking opera aria into the folklore Pai-Chang which was one kind performance and traditional custom of Peguan music Some people who came from other places and played Peking opera aria had also known or learned "Pai-Chang" with touching Tainan local amateurs "Pai-Chang" used to be performed by amateurs for worship of god or goddess or for seasoning and wedding celebration without rewards Amateurs volunteered to perform "Pai-Chang" only for their duty temples and fraternity of Peking opera aria The majority of the audience is people who perform or like "Pai-Chang" or who live nearby There is a fixed pattern of the performance including the repertoire and the arrangement of the band The main meaning of this performace is to pray God's blessings therefore the procedure of "Ban-Hsian" is the most essential and ahead of Peking opera aria singing With time goes by the number of the amateurs has dropped; yet the demand for the worship ceremony remains; hence some of the amateurs have been trained to become professional performers Besides although the idea and the meaning of "Pai-Chang" remains the pattern of the performance has become simplified and rigid which is because of the performers' number decreasing and market adapting Nowadays the whole ecosystem of the folklore Pai-Chang of Peking opera aria in Tainan city keep changing which is mainly influenced by the transition of the society(such as the time and space of the industrial and commercial society being compressed and most people's pursuing of specialization and utilitarianism etc ) According to the findings in this paper the phenomenon can be regarded as the subject matter both of Peking opera and folklore studies For the studies of the Taiwanese culture however the subject not only enriches the subject matters of the Taiwanese culture(signifies the localization of Peking opera and a new pattern of Taiwanese folklore) but also reflects the characters of diversification integration adaptation and compromise of Taiwanese culture which used to be influenced by different regimes and the historical contexts Facing such a multicultural context this paper thus suggests researchers should show an open-minded attitude toward the complex of the Taiwanese culture studies and then important phenomenon would not be ignored or misunderstood
代表了什麼意义?对於上述疑惑,查既有研究成果,不消没有论述者,具体提即「京调排场」现象的可说没有,基於此,有必要对台南市及其周边之民俗性京调排场,不管是语汇来由或者其现象本身,做一番研究。本研究透过文献、访谈、口述史、参与观察等方法,以文化有机体之纵的发展概念为经,以民俗表演之横切面各主客要素为纬,试图先对此文化现象调查并推论出一概貌:台南市民俗性京调排场的形成,是在京调传入台南,台南本地北管子弟改习或兼习京调后,结合北管音乐文化所固有的排场表演型态及民俗演出传统,融合而成,形成时间至迟在日治晚期。而一些不同时期的外来京调人士(如原本生长於其他地区、后移住台湾的票友,和中国大陆琴师等等),也曾透过与当地子弟的接触,而习得或知晓「排场」语汇以及本地京调排场习俗者。此项音乐民俗表演在过往多由业余子弟於神诞或民众婚俗做寿时,对其有义务或交陪的庙宇及子弟间做酬酢性的演出,不收报酬;聆赏者多是京调同好与邻近民众,也有少数路过者;演出模式包括节目安排、乐队编制皆有一定;表演意涵上以「扮仙」祈求神明赐福人间最为重要,因此排仙必不可少,且一定先於京调演唱。随著时间推移,京调排场表演活动的各要素都有变动,惟变迁速度不一,大体而言,业余表演者锐减,人们对酬神娱神节目的需求仍在,因此一些过往的业余表演者遂逐渐转型为职业表演者。此外,虽然表演意涵不变,但在职业表演人员少、又要适应市场的情况下,表演模式亦逐渐流於简化、僵化。目前京调排场整体生态仍在转变的过程中,而这种变化应与工商社会时间空间的被压缩、事事追求专业化与尼Q化等因素有关。再者,据此概貌,在结论部分厘清其意义、定位以及其对台湾文化研究之启示。台南市及其周边之民俗性京调排场现象,可视为京剧研究与民俗研究的一环,然而对於台湾文化研究,除了其题材本身标志了京剧的本土化与台湾民俗活动之新类型,进一步扩充整体台湾文化研究的内容外,更重要的是现象背后所反映的台湾文化的多元融合与妥协适应取向。台湾的海岛地理位置与长期被不同文化背景政权所殖民的历史,其文化自然容易随社会环境改变而弹性适应变迁,呈现多元纷呈、多重覆叠的特色,因此展望未来,从事台湾文化研究应秉除单一观点,保持一定程度之开放与客观胸襟,方不忽视或误识更多重要的文化现象。
