The results of numerical analysis show that the elastic modular and the poisson ratio have no effect on two-dimensional bearing capacity, but can affect the ultimate bearing capacity of three-dimensional foundations and control the convergence and precision of finite element calculation; the earth pressure coefficient controls the geostatic stress of foundation, sequentially affects the ultimate bearing capacity of foundations and the convergence of numerical calculation. When calculating the ultimate bearing capacity of undrained saturated foundation, the complete formulation exists shear locking, and reduce formulation exists hourglassing, so the hybrid formulation is suitable to imitate the geomaterial. When the soil obeys nonrelevent flow rule, the yielding function is different from potential function, and the elastic-plastic matrix of soil is asymmetric, so the unsymmetry numerical solver and appropriate finite element mesh is required.

研究结果表明，土体弹性模量和泊松比对二维基础极限承载力没有影响，但是影响着三维矩形基础的极限承载力，控制着ABAQUS数值算法的计算精度与收敛速度；地基土压力系数控制着地基土体中的地应力平衡，从而影响着二维条形基础和三维矩形基础的极限承载力和地基破坏包络面；对于不排水饱和软黏土地基，常规的完全积分单元会造成剪力自锁现象，而减缩积分单元则存在过于柔化的现象，故采用杂交单元来模拟较合适；当土体服从非关联流动法则时，屈服函数与塑性势函数之间存在差异，从而导致土体弹塑性矩阵呈现非对称性，在有限元计算中必须采用非对称数值解法，并且合理地划分单元才能对极限承载力进行准确求解。

Shearstrain were obtained forcomparison with those sug- gested by Seed and Idriss.The difference between shear wave velocities obtained in- situ and those obtained with resonant column testing are discussed.

粉土和粉砂结构性较差，在取土采样、运输过程中极易扰动失水，从而使室内试验结果失真；而重塑样又常常不能反映土体的原位性质，从而限制了对其工程性质的研究。

For determination of pyruvic acid, we used the ferrocene as an electron transfer mediator and pyruvate oxidase as a catalyzer, and had a systemic research for the immobilization of ferrocene and enzyme on the gold electrode. At last, a pyruvic acid biosensor with good stability and activity of electrochemistry and biocatalysis was constructed. There are two aspects of contents in the paper. The first step, we had an in-depth research for the immobilization of ferrocene on the gold electrode, and fabricated a modified gold electrode by glutaric dialdehyde cross-linked egg white as the matrix of ferrocene immobilization.

1Unequal number of univalents with decreased degree of synapsis and lagging chromosomes occurred in meiosis.The abnormal chromosomal behavior correlated with heterogenicity gave rise to unequal allocation of homogenous chromosomes to daughter cells and resulted in the deletion of functional chromosoms,thus led to the occurence of a certion proportion of aborted pollens.(2)The interaction between genetic imbalance and such environmental factors as temperature,etc.,further drew forth physiological and even structrural imbalance,with abnormal development of pollen mother cells and tapetal cells,and consequently resulted in no or very few production of pollens.The difference in the interaction between environment and genotype reflected on the unstability of pollen abortion in different years.

1在减数分裂中有数目不等的联合程度较差的单价体以及落后染色体出现，这种与异质性相关的染色体行为异常，导致同源染色体向子细胞的不均衡分配，造成具功能染色体的缺失，从而引起毛白杨一定比率的败育花粉的产生；(2)遗传上的不平衡与温度等环境因子相互作用，进一步引发毛白杨生理乃至结构上的不平衡，花粉母细胞和绒毡层细胞发育异常，从而造成不产粉或产粉较少；环境与基因型互作的差异性导致了花粉败育的年度不稳定性。

With the IAP Prediction System of Short-term Climate Anomaly, two sets of seasonal and extra-seasonal ensemble hindcasts have been performed during the period of 1980～1994 in order to assess the prediction skill of the IAP PSSCA with two different schemes The difference of the two schemes is in the different version of AGCM used, with the IAP AGCM 1 1 in one scheme and the IAP AGCM 1 2 with an improved surface albedo parameterization in the other Comparisons of the hindcast results with the observations show that IAP PSSCA is capable of predicting the precipitation anomaly to some extent In the eastern China largely affected by Asian monsoon and SST anomalies, the prediction skill is relatively high, especially in the Southeastern China where the anomaly correlation coefficient can reach as high as 0 50 in the severe flood and drought years This may suggest that the possible mechanisms for these severe disasters have been well captured by the IAP PSSCA The prediction skill is higher for the modified model AGCM 1 2 as the model's climatological state is well simulated This indicates that models with reasonable land process will improve the prediction skill for short-term climate prediction

利用中国科学院大气物理研究所研制的短期气候距平数值预测系统，种版本的大气环流模式：AGCM 1.1和AGCM 1.2，分别以2月11～19日的9天大气观测值为初始场，以给定海温为边界场，对1980～1994年的15年的降水异常进行了两组集合后报试验。对试验结果进行定量评估表明：IAP PSSCA对降水异常具有一定的预测能力，特别是在中国东部受东亚季风及海温异常影响的地区，IAP PSSCA具有较高的预报技巧，其中以东南区域(包括江淮流域和华南地区)最高，尤其是对有洪涝灾害的降水异常年，距平相关系数在0.50左右，接近可供业务使用的要求，说明模式能够抓住在东亚季风区存在的某种物理机制，从而提高了这一地区的预报技巧；另外，两个大气环流模式相比，改进了地表反照率的AGCM 1.2的15年集合平均预测技巧略高于AGCM 1.1，特别是在华北地区，预测效果有明显提高，这表明改进地表反照率从而改进了模式的气候平均态的模拟，能提高气候模式的预测能力，说明较好的陆面过程引入模式对短期气候预测是有益的。

DDMRA only recoveries incorrupted data items by malicious transactions to avoiding re-excution of innocent operations while transaction dependency methods undo-redo all operations of malicious transactions. In BDDMRA, benign blind writes can write bad data items to normal state thus corresponding malicious operations are not necessary to undo-redo and it will speed up recovery process.

The results showed that there were differences between adaption and regulation of different wheat varieties by prophyl dihydro jasmonate, so as to show diversity of gas exchange parameters, such as photosynthesis, water usage, etc. There was no evident difference between the reaction of two spring wheats (Jinchun1 and 1608) and the winter wheat (Xiaoyan 22) to PDJ. Different parameters of different wheat varieties had inequable reaction to different concentration of PDJ. Photosynthesis rate, water use efficiency and stomatal limiting value were enhanced when PDJ concentration reached a high degree. At the same time, leaf transpiration rate and stomatal conductance decreased. Therefore, wheat could maintain normal physiological activities while environmental conditions were changed.

结果发现，面对类似激素双氢茉莉酸丙酯调控下的不同品种小麦适应与调节存在差异，从而导致光合和水分利用等气体交换参数的表现也存在差异；两种春小麦（金春1号、l608）和一种冬小麦（小偃22）之间对PDJ的反应没有明显的冬春性间的差别；对不同品种、不同参数，PDJ起到作用的浓度不同，但无论如何PDJ都有相同的作用，当这种激素达到一定的浓度后，就会增强小麦的光合速率和水分利用率，增加气孔限制值，降低叶片的蒸腾速率和气孔导度，从而在外界条件变化时保持体内水分、延缓气孔关闭，维持体内正常的生理活动。

During this period it is more and more obvious that culture and economy depending on and stimulating each other. This will either, because our neglecting cultural build, cause the inharmonic development of culture and economy, even cause a"modern trap"made conflict between each other; or, because our making the best use of the situation and reinforcing cultural build, get hold of the unique opportunity to speed up the balancing development of culture and economy.

这个时期，文化与经济相互作用相互依赖乃至相互促进的趋势越来越明显，这既可以由于我们忽视文化建设，从而导致文化与经济发展互不协调甚至相互冲突的一个&现代化陷阱&；也可以是由于我们因势力导，抓住时机，大力加强文化建设从而促进文化与经济平衡发展的难得机遇。

Since the commutators of both sing-ular integral operators and fractional integral operator with BMO functions areone of the special cases of〓,so the discussion of the boundedness of〓notonly gives a new proof of the boundedness of the two commutators,but al-soweakens some of restrictions into discuss the problem,thus it impro-vessome of results inwith the method of complex analysis,show-ed boundedness of〓,then directly obtained boundedness of the commutato-rs of fractional integral operator with BMO functions.
