To understand the expansion of multicopy microRNA (miRNA) families in plants,we localized the reported miRNAgenes from Arabidopsis and rice to their chromosomes,respectively,and observed that 3.% of 117 miRNA genes fromArabidopsis and 3.% of 173.miRNA genes from rice were segmental duplications in the *** order to characterizewhether the expression diversification has occurred among plant multicopy miRNA family members,we designed PCRprimers targeting 48 predicted miRNA precursors from 10 families in Arabidopsis and *** from RT-PCR datasuggest that the transcribed precursors of members within the same miRNA family were present at different *** addition,although miR160 and miR162.sequences were conserved in Arabidopsis and rice,we found that theexpression patterns of these genes differed between the two *** data suggested that expression diversifica-tion has occurred in multicopy miRNA families,increasing our understanding of the expression regulation of miRNAsin plants.

运用自然分类和多维标度方法,研究了纳西族亲属词的概念结构。被试是63.纳西族大学生。结果表明,纳西族亲属词概念结构由6个类别构成:(1)父母;(2.与父母同辈的长辈;(3.兄弟姐妹;(4)同辈的姻亲兄弟姐妹;(5)媳妇和女婿;(6)祖父母、子孙、旁系或姻亲子侄。纳西族亲属词的概念结构有两个维度:(1)同辈／异辈;(2.照顾者／被照顾者。纳西族亲属词概念结构与汉族亲属词概念结构具有明显差异,这与两个民族的家庭婚姻制度和文化有关,也与语言有关。

The change in residents′ perception and attitude and resort life cycle are the basic problems in the course of resort evolution. This thesis sets up the dynamic model of residents′perception and attitude, analyzes the linkage between residents′ perception and attitude and the influential factors of resort life cycle, and finally, with a case study of Putuo Mountain, preliminarily discusses the relationship between resort life cycle and residents′perception and attitude. The research findings show that, although within development stage of life cycle, Putuo Mountain has already presented some signs of mature stage. The on-the-spot survey also indicates that, the local residents′ positive perception is stronger than their negative perception. But compared with residents in some other coastal resorts such as Haikou and Sanya, negative perception of residents in Putuo Mountain is more evident, as the result of the smaller tourism carrying capacity in Putuo Mountain. There are some influential factors that have great impact on tourism carrying capacity in Putuo Mountain: tourist-resident number ratio, residents′ benefit-cost ratio and characteristics of tourism resources. And the less influential factors are residents′ demographic character, tourist behavioral character and cultural differences between local residents and tourists. Therefore, effective measures should be taken to adjust the structure of tourism product for the purpose of expanding tourism carrying capacity, lowering its pressure, lessening residents′ environmental cost and enhancing their positive perception, which is the most essential prerequisite for the maturation of life cycle in Putuo Mountain.

In this paper, we analyze the problem of switching controls for control systems endowed with different actuators. The goal is to control the system by switching from an actuator to the other so that, in each instant of time, only one actuator is active. We first address a finite-dimensional model and show that, under suitable rank conditions, the controllability for the switching controls system without the controls constraint. Then, we studies a time optimal control problem (ρ) for the switching controlled systems. With the aid of Ekeland’s variational principle, we obtain the Pontryagain maximum principle for this problem.

During the DY105-12. 14cruise (R/V DAYANG YIHAO, November 2.03. on East Pacific Rise (EPR) 12.13.N, the submarine hydrothermal activity was investigated and the CTD hydrocast was carried out at EPR12.3.''N—12.54''N. From the temperature anomalies and the concentrations of magnesium, chlorine, bromine in seawater samples, we discover that magnesium depletes 9.3.—2..4%, chlorine and bromine enrich 10.3.—2..7% and 10.7%—2..0% respectively relative to normal seawater at the stations which have chemistry anomalies, moreover temperature and chemistry anomalies are at the same layer. The depletion of magnesium in the plume may be caused by a fluid lacking of magnesium which rises after the hydrothermal fluid reaches the equilibrium with ambient seawater, the enrichment of chlorine and bromine might be the result of inputting later brine which is generated by phase separation due to hydrothermal activity. In addition, the Br/CI ratio in the abnormal layers at the survey area is identical to that in seawater, which implies that halite dissolution (or precipitation) occurs neither when the fluid is vented nor when hydrothermal fluid entraining ambient seawater rises to form plume. From the abnormal instance at E55 station, it is very possible that there might exist a new hydrothermal vent site.
