In the first chapter, using fragments of COI gene, we studied the phylogenetic relationships among species of five familes of Acridoidea with MP and Bayesian methods. The results were as follows:(1) Species of Acrididae, Gomphoceridae and all the Arcypterinae species of Arcypteridae are monophyletic. Species of Oedipodidae are supported as a monophyleticgroup, Ceracrinae species of Arcypteridae cluter together to make a monophyletic group. Epistaurus aberrans and Xenocatantops humilis is a phylogenetic group, Stenocatantops splendens and Hieroglyphus banian is also a phylogenetic group.

我们首先利用COI基因序列片段，使用最大简约法、贝叶斯法研究了斑腿蝗科、剑角蝗科、斑翅蝗科、网翅蝗科和槌角蝗科5个科42种的系统发育关系，得到如下结果：（1）由所有网翅蝗亚科的物种与剑角蝗科绿洲蝗亚科和槌角蝗科的物种组成一个单系群；斑翅蝗科的物种组成一个单系群；网翅蝗科的竹蝗亚科的黄脊雷蓖蝗和青脊竹蝗聚在一起形成单系群；斑腿蝗科的长翅十字蝗和大斑外斑腿蝗亲缘关系较近，形成一个单系群；长角直斑腿蝗和等歧蔗蝗始终聚在一起，形成一个单系群。

Seed pods of Ibicella lutea, Martynia annua, and Proboscidea parviflora. No one has accused Martynia annua of being a carnivore. It just has shady relatives. Note the very spiny pod of Ibicella lutea and rather smooth pod of Proboscidea parviflora.

网站第二张图是三种植物的种子）左边的黄花单角胡麻种子布满棘刺；中间的 Martynia annua 并无列入食虫植物，它只是和亲戚长得有点像罢了；右边的 Proboscidea parviflora 种子则较为平滑。

The conditions to measure accurately and the principles to select parameters of the multi— probes EST method are proposed, and the theoretical research, computer imitation and the experiment on a machine tool prove that these principles and suggestion are necessary and effective. The influence of the initial value errors of the probes, the installation error of the probes system, and the remaining error caused by the radical error motion are analyzed quantitively on the measurement accuracy of the multi—probes EST method. The influence of the error caused by the probe's axes which is not in a plane and the perpendicularity error of the plane which the probe's axes is in to the stational axis are discussed on the measurement results.

结合理论分析，对这些EST方法进行了计算机仿真分析和研究，重点研究了这些方法的应用条件和误差分离精度，所得出的结论是：三测头法EST基本上能实现各项误差的完全分离，适于在位测量使用；二测头法在恰当地选择测头安装角的条件下，可以得到较高测量精度，适于大型零件圆度、圆柱度、径向圆跳动和全跳动的在位测量；对置两测头时域法可以在一定程度上改善单测头法测量精度，但对随机径向误差无能为力；对置两测头频域法存在严重的谐波损失。
