The controller for the inverted pendulum-cart is then designed by using this pole placement method. The design is rather intuitive and simple. The next design for the inverted pendulum is to use two-block and four-block H〓 optimal synthesis methods. The results are then analyzed from the viewpoints of fragility and robustness.

论文又采用H〓的两块问题和四块问题分别对倒立摆系统进行系统性的优化设计，并从脆弱性和鲁棒性两个方面对设计结果进行了分析，指出倒立摆H〓优化设计的主要问题还是没有鲁棒性。

Acute pancreatitis patients were grouped as MAP and SAP after 72 h according to the clinical manifestations. Results:All the indexes were significantly higher in the AP group（P.05）. Urinary trypsinogen activation peptide and serum procalcitonin were increased significantly after 48 h.The sensitivity、specificity and positive likelihood rate of TAP and PCT were 90.5％,87.5％,7.2 and 90.5％,82.5％,7.2 respectively.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
