Abstract: Employing the weakly nonlinear method and perturbation method, the evolution ofthe amplitude of Rossby waves when the topography slowly changes is studied. AKdV equation with a forcing term governing this evolution is obtained from the quasi-geostrophic vorticity equation, and the forcing term is induced by the slowly changing topography.

Abstract: In this paper, the shallow water equation is discussed, when the underlying surface is slowly changing. From the continuity equation and the equation of motion controlling the movement of the atmosphere, the slowly changing of the underlying surface is superimposed on the topography function as a small quantity, using the upper and lower boundary conditions of the atmosphere, the modified shallow water equation is obtained. In the modified shallow water equation, the slowly changing local horizontal divergence modifies the equilibrium between the local horizontal divergence and the local change of the thickness of the atmosphere. On the basis of this, the vorticity equation is obtained, which contains the slowly changing underlying surface.

Abstract: 农业管理措施影响下土壤微生物群落结构的变化是农业土壤质量研究的前沿问题。运用化学分析方法和 PCR- DGGE技术从土壤微生物碳氮量及基因多样性角度研究了长期不同施肥措施下太湖地区代表性水稻土 -黄泥土的表土微生物活性与分子多样性的变化。结果表明 ,施用化肥以及化肥和有机肥配施在提高土壤有机碳含量的同时 ,不仅提高了水稻土的微生物碳氮量 ,而且改变了微生物的群落结构 ;与长期单施化肥相比 ,长期化肥配施有机肥不仅显著提高了土壤微生物碳氮量 ,而且提高了土壤微生物的分子多样性 ;就土壤的微生物分子群落相似性来说 ,单施化肥下与未施肥下相近 ,而化肥配施秸秆下与化肥配施猪粪下接近 ,说明土壤的有机培肥对土壤微生物群落结构有重要影响。长期单施化肥下水稻产量的年际波动性显著大于化肥配施有机肥下 ,这进一步佐证了化肥配施有机肥显著促进了水稻土的生态系统初级生产力与较高的土壤生态系统稳定性。应用PCR- DGGE技术所揭示的微生物分子群落结构特点可以指示水稻土 10 a尺度的不同农业管理措施下的土壤质量变化

Abstract: Ficus tree is a key species in the ecosystem of tropical rain forest in Xishuangbanna. The animal community is established by feeding, perching and breeding on the fruits, leaves, branches, fallen leaves and branches of Ficus, and even in the soil under the tree. The community helps Ficus tree with pollination and spread. And a correlation between Ficus and animals is closely established in the ecosystem. The data were collected in Menglun tropical rain forest reserve, endangered plant migratereserve, banks of Luosuo river and living compound of botanic garden in Xishuangbanna, in the sampled sites in regular time. The data indicate that the animal community in the virginal tropical rain forest with abundant Ficus trees has a diverse structure and it has much more species.

Abstract: Scanning electron microscopy of the antennae of the Yulong ghost moths Hepialus yulongensis was observed. The form of the antennae, the sensillar types, and distribution of the various sensilla were examined. The antennae of He plains is filiform with scape, pedicel and 21-27 flagellar segments.The antennae of both sexes are of 2.3-2.7mm length. The scape is longer than the following segments. The cuticle of the antenna lacks the reticulation of raised ridges. Six types of sensilla found on the antennae of both male and female include sensilla trichodea, sensilla chaetica, sensilla coeloconica, sensilla basico-niea, sensilla squamiformia and Bohm' s bristles. Moreover, sensilla campani-form occur on the antennae of male moths. The sensilla trichodea are further subdivided into two types (designated A and B). Bohm' s bristles occur mainly on the scape, pedicel, and apical segment. The gradual increase in the number of sensillum coeloconicum along the base of flagellar segments and the decrease near the tip. There are two morphological types of the sensilla coeloconica include the center peg of long and short pattern. The sensilla coeloconica of both types lack the inward slanting fringe pegs in the depressed periphery.

Abstract: 塔里木河各源流的径流规律不完全一致,导致了塔里木河干流水源组成变化比较大。为了认识塔里木河流域的源流和干流径流规律的特点,为流域的水资源可持续发展提供依据,采用模比系数Kp值法、Morlet小波分析法、坎德尔(kendall)秩次检验法分别对塔里木河源流和干流阿拉尔站(1958~2007)年径流的丰枯变化、周期性、趋势性展开分析,经计算分析,塔里木河源流和干流丰枯同步频率为26%;周期尺度表现相对一致,存在17年的周期成分,径流趋势呈现不同,源流有增有减,干流则递减。
The uncertainty of runoff rules of Tarim River’s headwaters leads to the great change of composi-tion of Tarim River’s main stream. To analyze the runoff rules of Tarim River’s headwaters and trunk stream, and provide the basis for sustainable development of water resources, this study selects modulus coefficient Kp method, Morlet wavelet analysis method and Kendall rank test model to analyze the abundance, cycle and trends annual runoff rules of headwaters and Alar hydrological station (1958-2007) at main stream of Tarim River. The results show that, the frequency synchronization of abundance of headwaters and main stream is 26%. The existing cycles is 17-year cycle, the runoff trend of headwaters are increasing or decreasing, while decreasing at main stream.

Abstract: The acute toxicity test in mice shows that the LD60 of CoQ10 administered i.p. is above 500 mg/kg. The subacute toxicity test in dogs leads us to the conclusion that CoQ10 administered i.p., 60 mg/dog, daily for 15 days causes no significant adverse effects on their general conditions, haematological and biochemical indices. Autopsy and histological examinations also show no significant pathological changes in hearts, livers, lungs, spleens and kidneys in treated dogs. When administered i.p., 20 mg/kg and 10 mg/kg, CoQ10 increase the formation of plaque-forming cells in murine spleens by 0.49 and 0.41 respectively. The possibility of clinical applications of CoQ10 suggested by our results are discussed.

Abstract: 本文首次报道了白马蝠蛾的生殖系统和生殖习性。白马蝠蛾雌性生殖系统与鳞翅目其他昆虫不同:无粘液腺器官;成虫产卵行为特殊,卵散产,产后有用尾和足扫土盖卵的习性;成虫交配授精以精包方式进行。交配除提供雌蛾精子外,还能刺激产卵。雌蛾生殖力强,生殖期短,产卵最多768粒,最少364粒,一生平均621粒,生殖期平均4.2天;成虫历期平均6.2天;卵平均历期48.5天(温度12.6 ℃)。最适宜成虫交配与产卵的温度为12.5-19.0 ℃,相对湿度75%-90%。
