有一定结构地

"All of the structures were laid out in a grid pattern, which suggests that the entire community was planned and then built all at once, rather than piecemeal," Pullen said."This would indicate that the settlement was built with some strategic purpose -- perhaps as a military or naval outpost."

"所有的这些建筑都是呈井字形结构分布的，这就说明整个建筑群是先规划好后一次性完工的，而非零星地建造形成，"普伦说，"这也表明这一居住区是出于一定的战略目的而修建的，它有可能是陆军或者海军的前哨。"

In order to improve their water solubility, 4"-fatty amido-3"-sodium carboxylate azobenzene-4-sodium sulfonates were synthesized. They are azo compounds with two hydrophilic groups of carboxyl and sulfonyl. They decrease the surface tension in dilute solution slowly, and show some surfactivity, but are not surfactants. The probable reason is their relative strong hydrophile. Furthermore, their colors are not fresh and far from our destination.

为了改善其水溶性，改用对氨基苯甲酸为原料合成了4′-脂肪酰氨基-3′-羧酸钠偶氮苯-4-磺酸钠盐，以偶氮结构为主的亲水基团上连有羧酸基和磺酸基两个亲水性较强的基团，但可能由于其亲水性太强，在稀溶液中只能缓慢地降低溶液的表面张力，具有一定的表面活性，但不是表面活性剂，而且颜色不鲜艳，距离我们的目标较远。

The ratchetting experiments of 316L and 1Cr18Ni9Ti stainless steel cyclically loaded under proportional and nonproportional conditions were performed respectively.

通过对两种不锈钢材料分别进行比例和非比例应力循环加载棘轮效应试验，揭示了两种不锈钢材料的棘轮效应的一些特征，和导致这些棘轮效应特征的原因，得到了一些有意义的结果，为建立能较为精确地描述结构在多轴应力循环下的累积变形的本构模型提供了一定的实验及理论分析依

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
