The characters of powder are connected with the inside structure and synthesize-technics of materials. In this paper, we want to search a optimize technics of materials synthesizing, and prepare a kind of nanosize powder which shape like ball and have good dispersed character. At the same time, we want to obtain a bridge structure of Zn-O-Tb through dopping of Tb, which can achieve efficient energy transfer from ZnO hosts to excited states of dopants, The doped powder can eradiate blazing green light because of efficient emission buildup from dopants and ZnO hosts, and the powder can emission a pure light. And we want to research the structure in doped ZnO for the further research of low-tension fluorescence of ZnO.

粉体的这些特性无不与其内部结构特征和制备工艺有关，基于这些，本文的实验目的是希望能寻找一种合适的制备方法和优化工艺，制备分散性好的球形纳米颗粒，希望改善其表面形貌，同时，通过铽掺杂，希望得到一种Zn-O-Tb桥联结构，实现氧化锌基体向铽发光中心的能量传递，希望铽中心特征发射和氧化锌绿光发射能有效叠加增强，改善粉体的单色性，制备出好的复合粉体，分析清楚其结构，从而为后续低压荧光特性研究作准备。

In the robot soccer competition, the ball s moving status is always changing and fluky because of the shoving and friction. In most cases, it is very difficult to find a global optimal shooting path, or the planning path can not be achieved by the robot in time.

机器人足球比赛中，小球的运动状态因受到碰撞和摩擦变化剧烈，所以大多数情况下不存在全局意义上的最佳射门路径，或者规划的路径机器人在给定的时间内根本无法完成。

The tribological behavior of the fluoborate nanoparticles as lubricating oil additive was evaluated by four-ball test machine,where test conditions are following: load 100～ 700 N,rotating speed 1 200 r/min,testing time 10 min.

借助TEM、XRD对表面修饰纳米氟硼酸盐微粒进行了表征，并利用四球摩擦试验机对其用作润滑油添加剂的摩擦学性能进行了评价，试验条件为载荷100~700N，转速1200r/min，时间10min。

Another time the attention of all was attracted by a little brown dog, with its tail in the air, who had come no one knew from where, and was running about fussily in front of the ranks. All at once a cannon ball fell near it, and it squealed and dashed away with its tail between its legs!

又有一次，所有的人都注意到了不知从哪儿冒出来的一只褐色的小狗，它把尾巴翘得高高的，满怀心事地迈着小碎步，跑到队伍前面，忽然，附近落下一颗炮弹，它尖叫一声，夹起尾巴，跳到一边去了。

There were no bites on fakes, no sliding feet once he had position and for the millionth time, when the ball is gettable or near the guy, he is always in the mix.

没有被假动作骗到，一旦抢到防守位置绝不退让半步，当球飞在空中，他总是不断的争抢。
