不同行距引起大豆生长竞争。当某一因子的直接供应不能满足群体生长的需要而成为限制因子时 ,竞争便开始。本文主要从基因型、光、水、养分和杂草等 5方面综述过去 4 0年行距变化对大豆竞争资源的影响。研究表明 ,不同品种对行距变化的反映不同 ,其依赖于季节降雨和灌溉。有限结荚习性类型可获得较高产量 ,抗倒伏的大豆品种适于窄行种植。无限结荚习性大豆在一定的行距条件下也可获得最佳产量。与宽行大豆种植相比 ,窄行大豆栽培增加光截获 (LI) ,其原因在于LAI、消光系数的增加及分枝类型品种的选择。水分利用效率和蒸发蒸腾作用不受行距影响 ,但在灌溉条件下产量增加。行距变化对养分吸收影响较大 ,随着行距的减小 ,植株产量和N、P、K的吸收均增加 ,且增加幅度受施肥水平制约。行距不影响N素的固定。行距不影响杂草密度、萌发高峰及持续时期 ,但在窄行栽培条件下可减少杂草的数量及干重 ,再配以适量的除草剂可获得良好的除草效果。不同行距条件下的大豆生理反应、养分和水分的吸收及转运 ,不同冠层的光能利用以及土壤环境的变化仍需进一步深入研究。

Purpose: To analyze water-soluble(Ws) human lens proteins of fetus, adult and age-related cataract by two-dimensional IEF/sDsPAGE electrophoresis. Methods: DACM [ N- (7-Dimethylamino-4-methyl-3-coumarinyl) maleimide ] was used to determine the lens proteins sulphydryl (sH) ***: Protein sH contents in Ws lens proteins have no significant difference among fetus, adult and age-related cataract lens. This is different from the relative published results obtained in lens proteins of animal cataract model using similar sH detecting ***: IEF/sDs-PAGE electrophoresis demonstrated that there were much more fragmentation of crystallins during lens development and cataractogenic process. It is suggested that this phenomenon is likely to be due to further conformational changes in the fragmented cyrstallins during aging and cataractogenic process. Eye science 1999; 15:32-35.

since the Eighth International Workshop on Tropical Cyclones(IWTC-8), held in December 2014, progress has been made in our understanding of the relationship between tropical cyclone(TC) characteristics, climate and climate change. New analysis of observations has revealed trends in the latitude of maximum TC intensity and in TC translation speed. Climate models are demonstrating an increasing ability to simulate the observed TC climatology and its regional variations. The limited representation of air-sea interaction processes in most climate simulations of TCs remains an issue. Consensus projections of future TC behavior continue to indicate decreases in TC numbers, increases in their maximum intensities and increases in TC-related rainfall. Future sea level rise will exacerbate the impact of storm surge on coastal regions, assuming all other factors equal. studies have also begun to estimate the effect on TCs of the climate change that has occurred to date. Recommendations are made regarding future research directions.

The capacity to capture CO_2 was determined in several stoichiometric compositions in the Li_2O–Bi_2O_3 system. The compounds(Li_7BiO_6, Li_5BiO_5, Li_3BiO_4 and LiBiO_2 phases) were synthesized via solid-state reaction and characterized by X-ray diffraction, scanning electron microscopy and N2 adsorption *** samples were heat-treated at temperatures from 40 to 750 °C under the CO_2 atmosphere to evaluate the carbonate formation, which is indicative of the capacity of CO_2 capture. Moreover, Li_7BiO_6 shows an excellent CO_2 capture capacity of 7.1 mmol/g, which is considerably higher than those of other previously reported ceramics. Li_7BiO_6 is able to react with CO_2 from 240 °C to approximately 660 °C showing a high kinetic reaction even at CO_2 partial pressure values as low as 0.05.

A general procedure for constructing multivariate non-tensor-product wavelets that gen- erate an orthogonal decomposition of L^2(R~),s≥ 1,is described and applied to yield explicit formulas for compactly supported spline-wavelets based on the multiresolution analysis of L^2(R^s),1≤s≤3,generated by any box spline whose direction set constitutes a unimodular *** particular,when univariate cardinal B-splines are considered,the minimally sup- ported cardinal spline-wavelets of Chui and Wang are recovered.A refined computational scheme for the orthogonalization of spaces with compactly supported wavelets is given.A recursive approximation scheme for“truncated”decomposition sequences is developed and a sharp error bound is included.A condition on the symmetry or anti-symmetry of the wavelets is applied to yield symmetric box-spline wavelets.

＜正＞ Quantum teleportation of optical coherent states was demonstrated experimentally using squeezed-state entanglement. The quantum nature of the achieved teieportation was verified by the experimentally determined fidelity = 0.58±0.02, which describes the match between input end output states. A fidelity greater than 0.5 is not possible for coherent states without the use of entanglement This is the first realization of unconditional quantum telePortation where every state entering the device is actually teleported.
