They found that, while most tips were around 15 percent, the minimum percentage co nsidered appropriate, people dining alone tipped consistently more (19 percent ) and those dining in groups of four or more tipped considerably less (13 perc ent) than this 15 percent standard.

他们发现大多数小费约为15％，这是被认为恰当的最小比例；一个人就餐的小费往往较多（19％）而四个或更多人一起就餐时小费要比15％的标准值少的多（13％）。

Because of MRSs simple structure, energy-conservation, easiness to control, and higher practicality, the multi-robot system, which is composed of several wheeled mobile robots having perceptivity and decision-making capability, is the most typical system with good application prospects in coordinative MRS.

Whether the earth dam lapses in Seismic Response Analysis is mainly judged by two criterion, the Damage Value and the permanent displacement, so the difference of response between Multi-Point Input and One-Point Input, that is the Multi-Point Effect, is also checked by this two criterion.

由于土石坝在地震作用下的失效形式包括累积损伤破坏和过大的永久位移，本文从累积损伤和永久位移两方面研究土石坝多点输入相对单点输入地震反应有何不同，即多点效应如何，因此与多点输入分析相关的损伤值和永久位移的计算方法也在研究之列。

目的：通过人卵巢癌细胞及多柔比星耐药株的体外细胞毒性实验，探讨两种动物源性ω-3多不饱和脂肪酸对耐多柔比星人卵巢癌细胞系A2780逆转耐药性的作用。

About a Year and half after I had entertain'd these Notions, and by long musing, had as it were resolved them all into nothing, for want of an Occasion to put them in Execution, I was surpriz'd one Morning early, with seeing no less than five Canoes all on Shore together on my side the Island; and the People who belong'd to them all landed, and out of my sight: The Number of them broke all my Measures, for seeing so many, and knowing that they always came four or six, or sometimes more in a Boat, I could not tell what to think of it, Or how to take my Measures, to attack Twenty or Thirty Men single handed; so I lay still in my Castle, perplex'd and discomforted: However I put my self into all the same Postures for an Attack that I had formerly provided, and was just ready for Action, if any Thing had presented; having waited a good while, listening to hear if they made any Noise; at length being very impatient, I set my Guns at the Foot of my Ladder, and clamber'd up to the Top of the Hill, by my two Stages as usual; standing so however that my Head did not appear above the Hill, so that they could not perceive me by any Means; here I observ'd by the help of my Perspective Glass, that they were no less than Thirty in Number, that they had a Fire kindled, that they had had Meat dress'd.

我自从有了这些想法之后，平时就经常会想到这件事，可是因为没有机会付诸实施，因此一直都毫无结果。这样大约又过了一年半光景。一天清晨，我忽然发现有五只独木舟在岛这头靠了岸，船上的人都已上了岛，但却不知道他们去哪儿了。他们来的人这么多，把我的计划彻底打破了。因为我知道，一只独木舟一般载五、六个人，有时甚至更多。现在一下子来了这么多船，少说他有二三十人，我一个人单枪匹马，如何能对付他们呢！因此，我只好悄悄躲到城堡里去，坐立不安，一筹莫展。可是，我还是根据过去的计划，进行作战准备，以便一有机会，立即行动。我等了好久，留神听他们的动静，最后，实在耐不住了，就把枪放在梯子脚下，像平时那样，分作两步爬上小山顶。我站在那里，尽量不把头露出来，唯恐被他们看见。我拿起望远镜进行观察，发现他们不下三十人，并且已经生起了火，正在煮肉。至于他们怎样煮的，煮的又究竟是什么肉，我就不得而知了。

Auto-immune type: also known as methyl-dopa-type, hemolytic disease can be medication from 3 months to 4 years later, on behalf of drug: a - methyl-dopa, levodopa, phenytoin, phenacetin, chlorpromazine, indomethacin, etc.

自身免疫型：又称甲基多巴型，溶血发病可在服药3个月至4年后，代表药物有：a--甲基多巴、左旋多巴、苯妥英钠、非那西丁、氯丙嗪、吲哚美辛等

For the problem that the suppression of co-channel interference and suppression of noise can't be balanced in signal-to-jamming and noise ratio maximization method for the linear precoding of multiuser multiple-input multiple-output downlink systems, an improved scheme that the term of noise variance is modified as a piecewise linear function is proposed, in which the balance between suppression of co-channel interference and suppression of noise can still be maintained even when the noise variance is a small value through piecewise modifying the term of noise variance, and thus the bit error rate and capacity of the systems are further improved.

针对多用户多输入多输出系统下行链路线性预编码的信干噪比最大化方法中，共信道干扰抑制和噪声抑制不能有效平衡的问题，提出将其中的噪声方差项修正为以噪声方差为变量的分段线性函数的改进方案。该方案通过对噪声方差项的分段修正，在噪声方差的值较小时依然能够保持共信道干扰抑制和噪声抑制间的平衡，从而使系统的误比特率性能和容量得到进一步提高。
