And then some ellipses that AUGR estimator is better than the OLS estimator and AUGL estimator is better than the OLS estimator are given, respectively.Second, the definition of the almost unbiased unified biased estimator is proposed. This definition includes the familiar almost unbiased estimators in literatures, and it is the unified expression of the familiar almost unbiased estimators. Followed the biased and variance are compared of AUUB estimator and the unified biased estimator, respectively. AUUB estimator has smaller bias than UB estimator and the variance of AUUB estimator is between the variance of UB estimator and 4 times of the variance of UB estimator. Finally the properties of AUUB estimator are discussed. The conclusion is gained that there are parameters made AUUB estimator is better than OLS estimator in terms of their mean square error. The sufficient and necessary condition that AUUB estimator is admissible is given. The ellipse is given that AUUB estimator is

然后给出了几乎无偏统一有偏估计的定义，该定义包括了文献中常见的几乎无偏估计，实现了常见几乎无偏估计的统一表达式；接下来我们比较了几乎无偏统一有偏估计与统一有偏估计的偏度与方差，得出了几乎无偏统一有偏估计比统一有偏估计有较小的偏度，几乎无偏统一有偏估计的方差介于统一有偏估计的方差与统一有偏估计的方差的四倍之间的结论；最后我们对统一有偏估计的主要性质作了讨论，证明了存在参数K，S使得几乎无偏统一有偏估计在均方误差意义下优于最小二乘估计的结论，给出了几乎无偏统一有偏估计为可容许估计的充要条件，还给出了在均方误差阵意义下几乎无偏统一有偏估计优于最小二乘估计的椭球。

In this round of global stock market adjustment, the Hang Seng Index has fallen far less than the Shanghai Composite Index, but Hong Kong shares end stronger reason, there are several: First, A shares the current average price-earnings ratio of 15 times, while Hong Kong stocks average price-earnings ratio of only 8 times, funds flow to the lower, resulting in the recent Hong Kong stocks rose, while the A shares are still hesitate to move forward; secondly, The focus of the central enterprises to buy back into the H shares, a price comparison of the most typical is now China's oil price of A shares for more than 10 yuan, while the H shares with the right stocks, only 5 more than the Hong Kong dollar, of course, there are流通盘size factor, but China's oil major shareholders to buy back its own shares will not take this factor into consideration, if the major shareholders have to consider if the cost of repurchase, H shares more attractive is beyond doubt; and thirdly, the size of the non-lifting of the ban circulation is still pressure in the A share market, the head of a big mountain, but a typical example is the recent Haitong Securities to the size of the non-lifting of the ban period, the outstanding shares for 2.3386 billion shares of Haitong Securities, the size of the non-even up to 79.9396 billion shares, Despite the size of the non-release is gradual, all in circulation there is a process, but it hung a "barrier lake" effect of the market fears.

恒生指数的跌幅远远高于上海综合指数，但香港股市年底更有理由较少，有几个：首先，A股目前的平均价格市盈率为15倍，而香港股市的平均市盈率仅8倍的比例，资金流量较低，在最近香港股市上涨造成的，而A股仍毫不犹豫地向前推进；第二，重点中央企业将购回的H股，一个最典型的价格比较现在是中国的石油A股超过10元的价格，同时拥有股票的H股中，只有5较港元当然，有流通盘的大小的因素，但中国的石油大股东回购自己的股票将不考虑这一因素，如果大股东要考虑如果回购成本，H股更具吸引力是毋庸置疑的以及第三，大小非流通的禁令解除仍然在A股市场的压力，一座大山的头部，但一个典型的例子是最近海通证券的非规模的解除班期间，二十三点三八六亿海通证券，在大小非流通股股份，甚至高达7993960.0万股份，尽管大小非释放是渐进的，所有的流通有一个过程，但它挂1 &堰塞湖&市场担忧的影响。

The results of conversion show that the serious disc must be rejected because its reliable L-HCCF life is greatly less than an overhaul period. Finally, the load distribution of centrifugal and vibration force on labe is derived. Using two method, load on the crack labe gradually reducing and keeping constant with the crack propagation, a crack propagation analysis of fir-tree slot is carried out, and the calculating L-HCCF crack propagation life of slot on the unload method, which is nearly 3 times longer than that on constant method, is 20 times shorter than the pure low cycle life, and agree well with the experimental's.

最后，分析了离心力载荷和振动载荷在榫齿上的分布，进行了榫槽榫齿的有限元计算；提出了枞树型榫槽的卸载概念，并按带裂纹榫齿上的承载随裂纹增长而逐步减少和始终保持不变两种处理方法，进行了复合疲劳裂纹扩展及其寿命计算，由计算得出卸载下复合疲劳裂纹扩展寿命较单纯低周疲劳寿命下降二十多倍；按卸载处理的疲劳裂纹扩展寿命是按恒载处理的三倍多，前者与试验吻合，而后者则偏差较大。
