在VEPP^-2000e^+e^-对撞机上,CMd^-3探测器研究了e^+e^-→ηπ^+π^-→γγπ^+π^-,e^+e^-→ηπ^+π^-→π0π^+π^-π^+π^-以及e^+e^-→ωπ^+π^-→π0π^+π^-π^+π^-等过程.分析使用的是2011和2012年在1.2^-2.0Ge V能区收集的相应积分亮度为3×104nb^-1的数据.用η→γγ道测量了e^+e^-→ηπ^+π^-的波恩截面,结果与相关的实验结论相吻合;还用末态η→π^+π^-π0和ω→π^+π^-π0分别得到了e^+e^-→ηπ^+π^-和e^+e^-→ωπ^+π^-波恩截面的初步结果;e^+e^-→ηπ^+π^-波恩截面的数值还被用于确定τ^-→ηπ^-π0ντ的衰变分支比.

The effects of periodically inhomogeneous birefringence on dark-bright vector soliton propagation and interaction are investigated by the numerical method. The birefringence leads to the submergence of the dark soliton and the disintegration of the bright soliton, and enhances the interaction between the neighbouring solitons. The system performance is determined by the bright soliton because the dark soliton has robust features. Finally, the avoid.n.e and the effective control are introduced, and the controlling mechanism is demonstrated.

Alley cropping of Cassia siamea and maize was studied in semi arid Kenya for soil fertility improvement. Katumani composite maize was planted except in the short rains of 1988 (SR88) when a hybrid variety was sown. Therefore the grain yield per row increased differently in the alley cropped maize (CM). Sole maize (SM) and CM yields were higher in SR88 than in the long rains of 1988 (LR88) by 62% and 38%, while yields from the same treatments in LR89 were only 21% and 45% of those in SR88 These differences in relative maize yields are attributed to differences between the two maize varieties in competition under nutrient stress conditions.

Synthesis of ***（0.5-x）Fe204 nanoparticles with x=0, 0.1, 0.2, 0.3, 0.4 and 0.5 were realized via coprecipitation method. X-ray diffraction （XRd） and vibrating sample magnetometer （VSM） measurements were performed on the samples to determine the characteristics of the crystal structures and the magnetic properties of the samples, respectively. The spinel phase structures of the samples were confirmed by XRd analysis. Patterns of decreased lattice parameter and increased crystallite size values were observed by increasing the Li concentration at longer synthesis reaction periods. Similarly, for the magnetic properties, both the saturation magnetization （Ms） and coercivity （Hc） were found to vary with increasing patterns at higher Li doping levels and longer synthesis reaction periods. The results and mechanisms concerned were discussed.
