The relation of the chromatographic retention indices of alkene to topological index,double bond atomic hybridization state index,polarizability effect index of branched chain to double bond atomic,immobile liquid polarity values and column temperatureat different temperatures on different stationary phases was studied.

通过对部分烯烃在不同固定相不同柱温下的1031个样本集的气相色谱保留指数值与其部分参数关系的研究，发现RI与拓扑指数、双键原子杂化状态指数、支链对双键的极化效应指数、固定液极性值及柱温的关系可表示为：^RI=-58.138+57.7460Q-8.2591Q+0.120T+0.807CP+36.460PBD+7.919DHSI(R=0.9989)继以留一法(Leave-one-out，LOO)进行交互检验，相关系数RCV=0.9977，说明所建模型具有良好的稳定性和预测能力，较好地揭示了烯烃类化合物气相色谱保留指数RI随固定相极性、柱温的改变而变化的规律

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。

That consider condyle, bone caruncle of 5 exemple, cartilage fibrosarcoma of 3 exemple, nerve fibroma of 1 exemple, nerve 1. The symptom after 27 patients operation all has different level improvement, live on average without tumour time is 33.5 months. Incontinent companion meets the patient relieve oneself of S1 of 5 operations reservation or above nerve root pubic feeling is lost, after manager cure function trains, 3 parts restore, 2 conserve without progress; bladder and rectum function obstacle all appear after the 12 patients art of root of S2 above nerve, after training via rehabilitation physiotherapy and function, 10 return to normal basically, 2 patients still are put in the obstacle of be convenient to both of different level. 10 withhold S3 or the patient of above nerve root can conserve constrictor function.

It's hard to get away from art in Italy. Here's one last solely art-related suggestion, and one that quickly brings us up to the 20th century. The Giorgio de Chirico House-Museum is a chance to get a guided look at some of the signature works of the master of classically fueled surrealism and to get a peek into his sunny attic studio. The pristinely preserved two-level apartment, where De Chirico lived for more than 30 years until his death in 1978, also lets you glimpse how the city's upper crust have lived for centuries. In this case, it's accompanied by about the best view overlooking the splendid Piazza di Spagna. The living area has been left largely as it was during De Chirico's life and displays dozens of his works. Reservations must be made in advance.

在意大利艺术无处不在，下面给你一些建议，你可以去看下20世纪的近现代作品，里科的乔治加亚日众议院博物馆就是一个不错的去处，导游会带领你去参观一些超现实主义工程硕士们的阳光阁楼工作室，在那里至今保留了2个高规格级别的公寓，里科在那里居住了30年直到他1978年去世，你还可以去参观这座城市百年以上的老建筑，你可以在那些老建筑上面找到最佳俯瞰辉煌的西班牙广场的地方，至今保留有艺术家里科生活过的几十个地方，那里至今保留有他大量的作品。

On closer examination, though, this is not a vote for multilateralism but just the opposite.

仔细审视后我们发现，这并非是对多边主义投出的赞成票，而是恰好相反。

Uncovering their weak spots, so I can defeat them.

揭露出他们的弱点，这样我就可以打败他们了。
