There are some isoforms of PAPs showing inhibitory ability to virus infection in various organs and at different stages of development. Three different species of the protein can be isolated from leaves of pokeweed (PAP, PAPⅡ and PAPⅢ). Proteins were precipitated with 50-80% ammonium sulfate from leaves in spring, summer and autumn respectively. Proteins were purified on SP cation-exchange then on MQ anion-exchange and finally on MS cation-exchange or on MQ anion-exchange. We found that some new pokeweed antiviral proteins separated from these leaves were different from PAP, PAPⅡ and PAPⅢ.

The pattern of lunar cycle can be classified into three strategies:(1) Planulation of S. hystrix and P. damicornis showed clear lunar periodicity and the peak of larval release shifted with different months. The peak of planulation occurred around the full moon in winter then shifted gradually to the first quarter moon phase in summer. The phase shift of larval release may be related to the seasonal variation of seawater temperature and the sudden temperature drops caused by upwelling.(2) Planulation of S. pistillata showed clear lunar periodicity and the peak of larval release occurred around the full moon.

在月周期方面可分成三种生殖策略:(1)尖枝列孔珊瑚与细枝鹿角珊瑚释放幼生不但有明显的月周期,而且释放幼生的高峰会随著月份而移动,由冬季至夏季期间,高峰从满月前后转变至上弦月前后;再由夏季至冬季期间,高峰从上弦月前后转变至满月前后,而此变动形成一个完整的年周期,原因可能与海水温度影响配子发育和胚胎速度与夏季期间涌升流所造成的降温有关。

In this paper, the 3-D finite element relocating mesh method is used to calculate the temperature field and the thermal creep stress field of spillway dam and mid level outlet dam in certain roller compacted concrete gravity dam, sensitivity analysis have been down with different parameters, such as placing temperature, the location of cooling pipe, cooling temperature, time for water supply, ascended-layer of concrete, intermissive time and different placing time, and the commendatory construction scheme have been put forward in such analysis; according by the test result on the two scheme of concrete aggregate combination (basalt as coarse aggregate and limestone as fine aggregate, basalt as coarse aggregate and basalt as fine aggregate), simulation analysis on temperature field and thermal creep stress field of the commendatory construction scheme have been down, and analysis have also been down on temperature field and thermal stress field of the two different aggregate combination, the result indicates that the spillway dam and mid level outlet dam which adopted these two aggregate combination can both satisfy the require of design crack resistance in concrete, furthermore limestone as fine is better than basalt as fine aggregate; the effect of summer water storage and winter water storage on the temperature field and thermal stress field have been analyzed, comparing with winter water storage, in summer water storage scheme the maximum tensile stress at abnormal concrete in upstream fill is decreased by 0.1~0.3MPa and there are no evidence change of the maximum tensile stress at other parts, which indicate that summer water storage is avail for the crack resistance of upstream fill; according to the simulation calculating result and comparing temperature simulation calculating results and temperature controlling measures of some similarity projects both completed and construction, synthesis appraise have been carried to the design temperature controlling measures of dam, and the temperature controlling measures of this project have been brought forward, all these have great reference value on the design of temperature controlling measures and the optimization of the construction scheme.

If Ngai and Tenreyro are right, then the housing market dynamic is something like this: buyers slightly prefer to buy houses in the summer, so house prices are slightly higher in the summer, so sellers prefer to put their houses on the market in the summer, and with more houses on the market, the market is thicker.

Seasonal variation of the distributions of microorganism in the root-zones of wetland plants (Phragmites australis, Zizania latifolia, Zizania latifolia etc.), the substrate layers of control SSPs, together with the effects of wastewater treatment were studied. The results are as follows: the numbers of microorganisms in the different plant root-zones were different; the purification effects were also different. The number of microorganisms in the substrate of the control plot becomes smaller with increasing depth. The numbers of bacteria in fall were higher than those in the summer for the three plant zones and the control, and the number of fungi and actinomyces in summer was much higher than that in the fall for control. As for fungi and actinomyces in the experimental systems, most of their difference between the summer and fall were not as big as that in the control.

The results showed that obvious interdecadal variability of summer temperature was found,which was relevant to interdecadal variability of atmospheric circulation over the Asia.It also indicated that the important reason of summer temperature anomaly might be interdecadal variability of climate in Northern China.The circulation in mid-latitudes and high-latitudes in summer of 2003 took on two troughs and ridges,which was contrary to climate state of recent decades.The signs of climate shift were foreshowed in 2003 according to the characteristics of interdecadal variability.

结果表明:中国夏季气温变化有明显的年代际特征,这一特征与亚洲上空大气环流的年代际变化紧密相关,表明我国北方地区夏季气温异常一个很重要的原因或许是缘于气候年代际变化。2003年夏季中高纬环流形势呈两槽两脊的配置,与近十几年气候态分布刚好相反,因而从气候年代际变化的特征来看,2003年为预示年代际气候转型的征兆。

The Somali jet is rapidly enhanced two pentads prior to the onset of SCSSM, thus accelerating the eastward extension of the westerly over the Bay of Bengal and leading to the eastward retreat of the western Pacific subtropical high . At the same time, the rapid enhancement of SCS CEF can also result in the northward march of WPSH and the onset of SCSSM. The earlier establishment and stronger southerlies correspond to the earlier onset time of SCSSM, and vice versa. Both composite and correlation analyses show that the 150hPa Asia-Australia CEF in boreal spring has important influences on EASM.

相关分析和合成分析的结果还显示,春季150hPa亚澳越赤道气流对东亚夏季风有重要影响:当春季该气流偏弱时,北半球夏季西太平洋副高强度偏强,位置偏南偏西,南亚高压强度也偏强,这样的环流背景使江淮流域6—7月降水偏多,华南华北降水偏少;反之,当春季该气流偏强时,夏季西太副高强度偏弱,位置偏北偏东,南亚高压强度也偏弱,江淮流域夏季降水偏少,华南华北降水偏多。
