Then they had spoken with Miss Frandsen; she knew all about the ballet, and at one time, in Grand-mother's younger days, she had been the most beauti-ful danseuse at the theater; she had danced goddesses and princesses, had been cheered and applauded wher-ever she had gone; but then she had grown older—weall do—and so no longer had she been given principal parts; she'd had to dance behind the younger ones;and when finally her dancing days had come to an end, she had become a wardrobe woman and dressed the others as goddesses and princesses.
因此她们就又去和佛兰生小姐商量。这位老小姐懂得有关芭蕾舞的一切事情,因为在祖母还很年轻的那些日子里,她曾经一度也是舞台上的一位漂亮的舞蹈家。她扮演过女神和公主的角色,她每到一地都受到欢迎和敬意。不过后来她的年纪大了——我们都会如此——再没有什么主要的角色给她演了,她只能在一些年轻人的后面跳舞,最后她只得退出舞台,做些化妆工作——为那些扮女神和公主的角色化妆。

The times, to their eyes, must have been out of joint, and to the common folk must have seemed as insoluble and complicated as do ours today. It is not hard to see how easily many could have been led to believe that the time of confusion had been brought upon them by deep and darkling forces. No hint of such speculation appears on the court record, but social disorder in any age breeds such mystical suspicions, and when, as in Salem, wonders are brought forth from below the social surface, it is too much to expect people to hold back very long from laying on the victims with all the force of their frustrations.
时代,他们眼中,必须已脱离联合,以共同民俗必须有似乎不溶性和复杂,因为这样做,我们今天的人们不难看到,如何轻松许多已经可以主导相信的时候,混乱已提请后,他们由深及darkling力量,没有暗示这种投机将会出现在法庭纪录,但社会失序,在任何年龄的品种,如神秘的疑虑,因此当,因为在塞勒姆,奇观,还有出来的,从下面的社会面,这是太大的奢望人民掌握着回很长由偏重对被害人的一切力量,他们的挫折感。

The variable geometry truss mechanisms have been studied extensively and systematically by this project. The research plan has been completed all sidedly, and expected results have been obtained. Three new kinds of combination decahedrons and a new class of variable geometry truss mechanism, which is composed of an octahedron and three tetrahedrons connected in parallel form, are proposed. The position analyses for decahedrons, dodecahedrons, triple-octahedrons, combinations decahedron and a new type of structure of variable geometry truss mechanisms are presented by introducing additional extra linear displacement sensors and using resultant elimination and homotopy continuation algorithms. The method of kinematical analysis of variable geometry truss mechanisms is established.
