The conditional nature of the distribution over label sequence can depend on non-independent, interacting features of the observation sequence. CRFs offer a solution to the problems in Chinese shallow parsing with hidden Markov models or with maximum entropy Markov models. First, as HMMs are generative, it is hard to employ overlapping features and nonindependent features of the inputs such as surrounding words.

通过单个状态将增大的或减小的概率和传递到它们的后继状态，使得这个单一的分布不需要对每个状态进行归一化，整个状态序列可以一起描述，从而克服了HMMs和 MEMMs的标记偏差（1abel bias）问题，而标记偏差的问题在汉语浅层分析中是个严重的问题。

In addition, the parameters sum of conditional heteroscedasticiity function tend to zero as aggregation level m approach to infinity, and conditional heteroscedasticity almost disappears.

最后，随著加总水准m愈大时，条件变异数方程式的参数加总趋近於零而条件异质性也跟著消失。

In this paper, we study characterizations of admissible in the general linear model Y, Xβ,ε|ε～(0,σ~2∑. We demonstrate that an admissible linear estimator is as the conditional generalized ridge-type estimation in the no constraint, equality constraint, inequality constraint general linear model. We study the superiority of this conditional generalized ridge-type estimation, and prove that it is superior to the restricted best linear unbiased estimator in terms of mean squares. We also give the choice of the matrix K.

本文主要研究了一般线性模型Y，Xβ，ε|ε～(0，σ~2∑中参数估计的可容许性特征，得到了一般线性模型在无约束，有等式约束及有不等式约束下，可容许线性估计均具有条件广义岭估计的形式的结论，并且讨论了这一条件广义岭估计的优良性，证明了其在均方误差和均方误差矩阵意义下都优于约束最小二乘估计，给出了参数矩阵K的选取方法。

A fuzzy conditional expectation with respect to sub σ-algebra of for a fuzzy random variable is introduced in the complete probability space, and the fact that such a fuzzy conditional expectation exists uniquely is proved and its some properities are discussed.

在完备的概率空间中引进一个模糊随机变量关于■的一个子σ代数■的模糊条件期望，并证明这样定义的模糊条件期望存在且唯一，还就其某些性质作了讨论。

It is also found that both permanent and transitory components of the conditional variance really exist and the shock of the temporary component of conditional variance is larger than the permanent component. Because there is no limit up or down in ADR's secondary market, the temporary shock of stock return is larger than the permanent shock.

而在条件变的部分，确实存在恒常要素与短暂要素，而且短暂要素的冲击效果明显大於恒常要素，显然在没有涨跌停限制的ADR次级交市场中，一旦面市场资讯的冲击时，短期股价报酬之反映较长期得剧。

Thirdly,quasi-normal inequalities of a-variation maximal operator and a-conditional variation maximal operator of scalar predictable tree martingales areidentified by the use of martingale transforms and by the construction of convex or concave function method;on this basis and with the help of previsiblity or regu-larity,Burkholder-Davis-Gundy\'s inequality of a-variation maximal operator and a-conditional variation maximal operator of scalar predictable tree martingales are iden-tified by the application of Hardy-Lorentz interpolation theory.At the same time,bythe use of G.

China and South Korea have excoriated Japan over its approval of new school books which they say whitewash the atrocities committed during Japanese occupation, and anti-Japanese protests have been held in Chinese cities. The lingering bitterness over Japan's past imperialism still threatens to mar relations between the big East Asian powers

中国和韩国强烈谴责日本通过新的中学历史教科书，他们认为这一教科书掩盖了日本在其占领期间所犯下的残酷暴行，反日抗议活动在中国数座城市发生，历史上日本帝国主义制造的痛楚无法被忘却，这有可能破坏东亚强国间的关系。
