Firstly, we defined a series of new concepts as the schemata containment, schemata competence, schemata intersection, and schemata dominance. Then, we defined the GA schema deceptiveness based on primary schemata competence, including complete schema deception, consistent schema deception, sequential schema deception, and basic schema deception.

In this paper, a path planning method based on GA is presented. Firstly, the model of the space robot is built to display the mapping of the end velocity and the joint velocity. Then the optimal algorithm based on genetic algorithm is presented to search the optimal solution which minimizes the disturbance of base attitude in the feasible solution space. Finally, an illustrative example is used to verify the feasibility of the algorithm.

基于GA研究机械臂运动对基座的姿态扰动问题，首先，建立空间机器人的运动学模型及空间机器人末端与关节速度之间的映射关系；接着，应用GA作为最优化算法，在空间机器人可行解空间中，寻找最优解得到最优路径，以达到对基座姿态干扰最小的目的；最后，通过数值仿真实验验证算法的实用性。

Advance in the study of Neoproterzoic mafic-ultramafic rocks in the western margin of the Yangtze craton has been reviewed in this paper. These rocks consists of 0.95—0.90 Ga orogenic rocks and 0.86-0.74Ga anorogenic rocks, which reflect Neoproterozoic tectonic evolution from arc to intra-continental rift in the area.

本文著重总结和评述了扬子地块西缘的新元古代镁铁超镁铁质岩的最新研究成果，认为这一期岩浆活动是由约0.95~0.90 Ga造山带的岩浆活动和0.83~0.74 Ga非造山的岩浆活动组成，反映了从岛弧到板内裂谷的构造演化模式。

That accounts forwhy Ga clusters occupy both the half unit cells of the 7×7 in thegrowth process.

初步的第一原理计算表明单个Ga原子吸附在7×7单胞的两半具有几乎相同的吸附能(差别仅为5meV)，这意味着Ga原子会随机地占据7×7单胞的任意一半成核生长，从而Ga团簇对7×7单胞不存在优先占据的特性。
