Based on the formula derived from the concept of phase margin, a new optimization tuning method of PID parameters was proposed. It found out the best value of K and T、T by using twice linear search, respectively. The formula derived in this paper are consistent with those in CHEN's paper where they are derived based on geometric graph, while the former are easy to comprehend.

提出了一种PID参数最优整定方法，两次采用线搜索分别整定出K和T、T根据相位裕度的概念推导出的参数整定公式与基於几何图形推导出的参数整定公式一致，但更容易理解。

Note that these 32 subsets include T itself and the empty set, which contains no elements at all.

由于 中的每一个元素都属于T，所以我们说S是的一个子集由于T有五个元素因而T共有的一个子集。

条件。 3。集装箱海运运费目前，集装箱货物海上运价体系较内陆运价成熟。

Upon to Ljapunov's concept of motion stability, the dynamic instability should be understood as the existence of at least one perturbed motion, which is initially in the small neighbourhood of the undisturbed motion and which starts at t =t〓, when is singular for the first time, depart monotonically from the neighbourhood, this phenomenon is proposed to be referred to as the quasi-bifurcation phenomenon.

按J〓运动稳定性概念，动力失稳应理解为在基本运动的小邻域内至少存在一种干扰运动会偏离基本运动并单调增长，偏离发生在时刻t=t〓，此时切线刚度矩阵奇异。这是所谓准分叉现象。

He only other area where the T-MAC 3 was not quite up to snuff was traction. The T-MAC 3's solid rubber outsole wasn't bad in terms of grip, but it could have been a lot better.

-MAC 3唯一没有达到的地方就是其牵引力，T-MAC 3的硬橡胶外底在抓地力方面其实还不错，但它可以做的更好。

Their thermotropic phase behavior was investigated by differential scanning calorimetry and POM. It was found that T(subscript S-N) w and T(subscript N-I), of PMMAZO was slightly increased with the increased of the mass ratio of liquid crystal block segments. PEO and PMMA block affected the liquid cystal behavior of PMMAZO. Meanwhile, PMMA and PMMAZO obviously influenced the crystals property of PEO segments3 which was decreased as the increase of molecular weight of PMMA and PMMAZO segments.

以差示扫描量热仪和偏光显徽镜研究了ABC三嵌段共聚物PEO-b-PMMA-b-PMMAZO的热力学相转变行为，发现随着PMMAZO链段的质量百分比的增加，三嵌段共聚物中PMMAZO链段的T和T逐渐提高；同时，PMMA和PMMAZO链段的长短影响PEO链段的结晶性，随着液晶段PMMAZO和PMMA链段分子量的增加，PEO链段的结晶性减弱。

Some of these mechanisms are a simple one position affair like on the T-2's while the T-1 and Gara both have two or three positions.

有些鞋的开关只有一档可调，比如T-2，而T-1和GARA则有二或三档可调。

The earlier period medicined diet can accelerate the hyperplasy of Peyer's patch cell in the intestinal tract, improve the proportion of T-lymphocyte subsets, and eventually improve the immunity function of intestinal tract.

早期药膳饮食有利于肠道Peyer's结淋巴细胞的增生，并改善Peyer's结T淋巴细胞亚群的比例，从而改善烫伤大鼠肠道免疫功能。

The desulphurization efficiency increases with the rise of Ca/S ratio. When the Ca/S ratio is 1. 4 and △T is 12 ℃, the desulphurization efficiency of the Baoshan slaked lime could be more than 90%.

采用宝钢消石灰作脱硫剂，当Ca/S比为1.4、△T为12℃时，脱硫效率可达90％以上。

Karen's Gaelic singing is well-represented, notably on the lovely Seinneam Cliù Nam Fear r, the vocal highlight of the album. She switches to English for a brace of anti-war songs, John Martyn's poignant Don't You Go and Donald Shaw's Soldier Boy.

Karen的声音也依旧动人，温柔里的魄力在两首反战歌曲Don't You Go和Soldier Boy里表现得淋漓尽致。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
