The reason for the second condition is that firms are less likely to raise prices to anticompetitive levels if it is fairly easy for new competitors to enter the market and drive prices down.

第二个条件的原因是：倘若一家新的公司可以平等地且很容易地进入市场，从而使价格降低，那么市场上原有的公司将价格提高到一个限制竞争的水平的可能性就很小。

A country in the Apennines near the Adriatic Sea. It is surrounded by Italy and is the world's smallest republic. According to tradition, it was founded in the fourth century a.d. and has succeeded, with a few brief interruptions, in maintaining its independence because of its relative inaccessibility.

圣马利诺：世界上最小的共和国，位于亚平宁山脉靠近亚得里亚海沿岸，周围被意大利环抱，传统上认为它建于公元 4世纪，并且因为它相对难以接近，而成功地保持了独立，有几次短暂地失去独立。

The experimental results reveal that there is no apparent difference in the frequency of sounds generated by the friction and collision between two stones, although the sounds may differ in pressure.

由实验结果可知，摩擦与撞击这两种不同的运动机制所产生的地声音频讯号，除声压强度上会有显著的差异之外，其在频谱上并无太大的差异性存在，这可能是因为摩擦运动基本上也可视其为无数个小撞击运动，因此其所产生之地声声纹基本上大同小异。

The common method, that all strong-correlation terms of the model are eliminated, can bring the loss in the engineering application, so the new method is proposed that the identified model reserves some correlation. The augmented matrix A is constructed by the outputΔW and the matrix S. The"determinating order based on ratio of determinant"is brought out to screen the strong-correlation terms in the structure identification. The latent root estimation is improved in screening the eigenvalues and eigenvectors. Thus the estimation precision is improved greatly.The consistence check of guidance instrument error coefficients of flight test and ground test is the purpose of flight experiment. The causes of inconsistency of the two models are analyzed. The hypothesis test of linear regression model based on F statistics is proposed to check the consistence.Finally, the instability of error coefficients is probably caused by the change of the flight environments, therefore, the relation between the error coefficients and flight environment is analyzed. The approach is presented to identify SINS guidance instrument error models and compensate the error in the segmented sections corresponding to the change of vertical acceleration of aircraft.

在结构辨识中，常用的方法由于将模型中的强相关项全部剔除而给工程应用带来损失，因此，本文提出了新的有益思想，即在保留一定相关性的基础上进行辨识：将输出向量ΔW与环境函数矩阵S构成增广矩阵A，然后采用"比定阶行列式"来剔除相关向量的方法，这样既可以尽可能多地保留了对落点影响大的强相关参数，又可以对落点影响小的强相关参数给予剔除；在参数估计中，改进了特征根估计中特征根和特征向量的筛选方法，提出"近零"准则，从而大大提高了参数估计的精度；再者，鉴于天地模型"一致性"检验是飞行试验和SINS制导工具误差系数分离的主要目的，因此，本文又深入分析了造成天地模型不一致的原因，提出了采用基于F统计的线性回归模型假设检验方法来进行捷联制导工具误差模型的天地"一致性"检验；最后，鉴于飞行环境剧烈变化可能会对惯性仪表误差系数稳定性带来一定的影响，因此本文深入地分析了SINS制导工具误差系数与外界环境的关系，提出了基于过载变化大小的分段辨识和分段实时补偿的算法。

Perhaps the only thing more aurally challenging than a roomful of novice violinists screeching their way through "Mary Had a Little Lamb" is a roomful of novice violinists screeching along on out-of-tune instruments.

或许，比满满一屋子小提琴初学者荒腔走板地弹奏"玛丽有只小绵羊"更让人听觉受刺激的一件事就是，这帮人毫无音调地在摆弄手中的乐器。

Like a wild beast mortally wounded, bleeding and licking its wounds, for five weeks the French remain in Moscow, attempting nothing; and all at once, with nothing new to account for it, they flee back; they make a dash for the Kaluga road (after a victory, too, for they remained in possession of the field of battle at Maley Yaroslavets); and then, without a single serious engagement, fly more and more rapidly back to Smolensk, to Vilna, to the Berezina, and beyond it.

他们犹如受了致命伤的野兽，流着血，舔舐着伤口，五个星期呆在莫斯科毫无动静，突然，毫无缘由地向后逃跑；窜向卡卢日斯卡雅公路，同时，（在打了胜仗之后，因为小雅罗斯拉维茨城附近的战场对他们有利），一仗也不打地退得更快，退向斯摩棱斯克，退离斯摩棱斯克，逃至维尔纳，逃至别列济纳河，向更远的地方逃跑。

He curled them between his palms at whiles and swallowed them softly.

他不时地用双手把它搓成小卷儿，轻轻地咽下去。

CHAPTER XVII Chinese THE ACTIONS of the Russian and French armies during the retreat from Moscow to the Niemen resemble a game of Russian blindman's buff, in which there are two players, both with their eyes bandaged, and one rings a bell at intervals to let the other know of his whereabouts.

第十七章英文在从莫斯科撤退到涅曼的途中，俄、法两国军队的行动就像是一种捉迷藏的游戏。两个作游戏的人都被蒙上眼睛，其中一个人不停地、时断时续地摇一个小铃铛，铃声把自己所在地点告诉了对方。

Small bluestone in the blue sea is pleased to scream together, it finally got his wish to come to the sea!

小青石在蓝蓝的大海里高兴地尖叫起来，它终于如愿以偿地来到了大海！

Simple farewell, the old turtle into a small bluestone river slowly pushed inside.

简单地道别后，老乌龟把小青石慢慢地推进了江水里。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
