不保留

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。

Those who believe in capital punishment may have arguments for its retention, but su rely no reasonable can be found for retention of the sickening mumbo-jumbo that accomp anies it from the moment that the judge dons the black cap with what looks like a pen-w iper balanced on the top of his wig, to the reading of the burial service over the condem ned man before he is dead.

那些相信死刑的人可能有保留死刑的理由，但肯定找不到合理的论据来保留那令人厌恶的繁文缛节。这一套繁文缛节从法官戴上顶在假发上的擦笔布似的墨帽子宣判死刑开始，一直伴随到为被判处死刑的人在其毙命之前诵读葬礼祷文为止。

Like the ancien régime in France, which believed that feudal property could be maintained by conservative force of law despite the modernization of society, the owners of bourgeois culture expect their law of property to provide a magic bulwark against the forces they have themselves released.

就像法国的旧政权曾经相信，保守的法律力量能够在社会的现代化过程中保留（维持？——是有新的同时保留旧的？还是仅仅维持旧的不变？）封建所有制一样，资产阶级文化的所有者也期望，他们的所有权法律能够在他们自己释放出的冲击力之前筑起一道防护堤。

The retention system fails if it cannot support the mechanical loads or if the maximum instantaneous deflection of the retention system exceeds 30 mm.

保留系统发生故障，如果它不能支持的机械负荷或瞬时最大的偏转保留系统超过30毫米。

One could denature the DNA, and then subject the single-stranded sample to CsCl centrifugation.

CsCl梯度离心的结果虽然排除了全保留复制的可能性，但不能根据这一结果就可证明DNA的复制是半保留复制，因为弥散复制也会出现同样的结果。

Thus, should we own 10% of Corporation X with earnings of $10 million in 1980, we would report in our earnings (ignoring relatively minor taxes on intercorporate dividends) either $1 million if X declared the full $10 million in dividends;$500,000 if X paid out 50%, or $5 million, in dividends; or zero if X reinvested all earnings.

最后若是持股比例低于20%，则依照会计原则，投资公司仅能认列被投资公司实际发放的股利部份，至于保留而不发放的部份盈余则不予理会，也因此假若我们持有一家X 公司10%的股份，又假设X公司在1980 年共计赚了1，000万美金，若X公司将盈余全部发放，则我们可认列100万的利益，反之若X公司决定保留全部盈余不予发放，则我们连一毛钱都不能认列。

No matter how bad the world may become, no matter how much the mass man of the future may lose such of the virtues as he still has, one fact remains. If one person alone refuses to go along with him, if one person alone asserts his individual and inner right to believe in and be loyal to what his fellow men seem to have given up, then at least he will still retain what is perhaps the most important part of humanity.

不管世界会堕落到什么地步，不管未来的大众会丧失多少他们迄今为止还保留着的美德，有一个事实依然不变：只要有一个人不肯跟着随波逐流，只要有一个人还会坚持自己植根于心灵深处的权利，信守他的同胞似乎已经放弃的美德，那他至少还会保留着也许是人性中最宝贵的东西。

Teletext business card printing and membership card making length can be done by changing the printing cylinder lining thickness, this point has been the consensus of the members.

图文制卡和会员卡制作长量可以堵住保留印版滚筒的包衬厚量而爆发保留，这一不面已得回了不小家的共鸣。

But there's also a powerful financial reason behind the preference, and that has to do with taxes. The tax code makes Berkshire's owning 80% or more of a business far more profitable for us, proportionately, than our owning a smaller share. When a company we own all of earns $1 million after tax, the entire amount inures to our benefit. If the $1 million is upstreamed to Berkshire, we owe no tax on the dividend. And, if the earnings are retained and we were to sell the subsidiary - not likely at Berkshire!- for $1 million more than we paid for it, we would owe no capital gains tax. That's because our "tax cost" upon sale would include both what we paid for the business and all earnings it subsequently retained.

当然除此之外还有一个重大的财务理由，而且是跟税负有关，根据税法规定，持有80%以上的股权比起拥有少数股权对Berkshire要有利的多，当一家完全由我们持有的公司税后赚了100万美元，这笔钱将全数纳到我们的口袋里，Berkshire不会因为收到股利而被课任何的税，而且如果我们将盈余全数保留，之后再把这家子公司出售-当然Berkshire是不可能做这样的事，那么就算之后的卖价超过100万美元，我们也不必为此支付任何的资本利得税，原因在于我们在税法上的成本包含我们先前买下该公司的成本以及以后年度保留的所有盈余。

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。
