FeSi nanoparticles were synthesized via thermal decomposition of iron pentacarbonyl in the solution of dioctyl ether, stabilizers oleic acid and oleylamine. The TEM images showed that FeSi nanoparticles had cubic shape, but it seemed that the composition was not uniform. According to the EDS results, the Fe:Si ratio of gray-uniform nanopaiticles was almost 1:1, and blacker FeSi nanoparticles contained more Fe atoms. Although FeSi didn't have uniform structure, it still could be proved that the incorporation of Fe and Si existed in a single nanoparticle. All possible structure, lattice, binding, morphology, surface condition would be discussed. These results indicated that perhaps FeSi2 was the main structure of the new products; however, due to incompletely combination and less synthesized time, it might still contain some part of Si and Fe structure. Besides, FeSi nanoparticles preserved the optical properties from Si atoms, but the PL intensity was much lower. The maxima PL peak appeared at 388 nm with the excitation at 300 nm. Their saturation magnetization, remanent magnetization and coercivity were measured by the SQUID, exhibiting their nearly superparamagnetic behavior.

利用热裂解系统可成功将研磨矽奈米粒子及五羰铁结合，制备出铁矽奈米粒子；从穿透式显微镜照片可知其粒子呈现立方体型态，但颜色深浅及组成不均，EDS结果则显示颜色均匀之粒子铁与矽之组成大致为1：1，颜色较深之粒子则含有较高量的铁元素；尽管组成比例并不统一，但单颗粒子同时含有矽与铁两种元素，初步说明铁矽奈米粒子之形成；进行多种结构与表面分析并探讨所有可能之键结、结构及表面元素后，推测铁矽奈米粒子可能以FeSi2之结构形成，并同时包含未重组完成的矽及铁之结构；利用PL分析得知铁矽奈米粒子确实保留矽之放光特性，并在300 nm激发光源下，於波长388 nm处有一最强放光特性峰，但整体发光效益不及研磨矽奈米粒子之结果；最后，利用超导量子干涉磁化仪量测其饱和磁化量、残留磁化量、与矫顽磁力，发现磁滞现象并不明显而几乎呈超顺磁性。

Part of counties without paddy-field-fish-culture have a decreasing effectiveness of using pesticide and chemical fertilizer (such as PingLe, GongCheng, YangShuo, RongAn, GuiPing, HengXian), while they still obtain a lower annual average unit area yield than the counties with fish culture in.paddy fields.

部分非稻田养鱼县(如平乐、恭城、阳朔、融安、桂平、横县等)大量使用化肥农药的增产效率明显减少，其稻谷年均单产量仍普遍低于同区域的稻田养鱼县的稻谷年均单产量。

The criterion is similar to hyperbolic strength criterion including uniaxial compression strength and uniaxial tensile strength, which is an extended form of Griffith-Murrell criterion essentially under the condition of polyaxial stress when hydrostatic pressure is lower, and it represents the first failure type. However, the criterion is similar to generalized Mises criterion when hydrostatic pressure is higher, and it represents the second failure type. The transition part between the two criteria represents the third failure type when hydrostatic pressure is high.

该准则包含单轴抗压和抗拉强度，在静水压力较低时，实质上它是Griffith-Murrell准则在多轴应力状态下的一种扩展形式，反映脆性岩石破坏类型1；在很高静水压力下该准则可转化为广义Mises准则，反映脆性岩石破坏类型2；而当静水压力较高时，该准则处于上述两种准则的过渡阶段，反映脆性岩石破坏类型3。
