In-situ monitoring gave the following results: 1 a tension stress zone occurred at the bottom of reinforced rock mass which indicated that the role of rock bolting was remarkable; 2 stress concentration at surrounding rock of main shaft was gradually transferred from shaft wall to complete rock mass far from shaft center; 3 vertical displacement was gradually smaller from up to bottom and from center to outside of the reinforced loose rock mass.

首先，建立了主溜井三维有限元计算模型，模拟了主溜井围岩的塌落破坏过程和加固后的加固体的稳定性及变形特性；同时，还采用多点位移计等对加固体的稳定性进行了实地监测。计算结果表明：网棚锚注加固体的纵剖面上的压力和位移规律是①加固体下部局部出现拉应力区，表明锚杆的使用是合理的；②加固体内的应力由塌落中心向周围围岩过渡，应力越来越大，最终将荷载传至围岩中；③从下到上下沉逐渐减小；④从加固体中心到周围下沉位移逐渐减小，且近似一条抛物线。

The friction and wear experiments results show that sticking wear takes place during the friction procedure, which results in the poor wear-resisting property of ternary eutectic alloys, due to the low quantity of hard particle of primary phase SnSb; the wear-resisting property of rapidly-solidified Pb-15wt%Sn-15wt%Sb ternary hypereutectic alloys is better than that of as cast ternary hypereutectic alloys.

摩擦磨损实验结果表明，由于三元共晶合金中作为硬质点的初生相SnSb的数量很少，所以在摩擦过程中发生了粘着磨损，导致合金耐磨性能较差；而Pb-15wt%Sn-15wt%Sb三元过共晶合金快速凝固合金的耐磨性能比普通铸态合金的耐磨性能好。

The existence ofpolar nanoregions dramatically influences the extrinsic dielectric nonlinearityof paraelectric phase. 5 Slow relaxations of field induced piezoelectricresonance of paraelectric barium stannate titanate were observed after eitherapplying or removing a DC bias field. This phenomenon is attributed to slowspace charge dipoles formed by injected homocharges and validated by theobservation of a negative piezoelectric constant. Isothermal study ondielectric constant and discharging current after application or removal of astep field were performed. The relaxation laws in ferroelectric andparaelectric phases are different. The transportation of homocharges arebelieved to be responsible for the strong relaxation behavior in paraelectricphase. Domain wall can trap space charges thus the relaxation in ferroelectricphase is relatively weak. Abnormal phenomena, such as slim-waisted hysteresisloops, abnormal C-V curves and clockwise reversible hysteresis loops observedin barium stannate titanate ceramics, were attributed to pinning of gatheredpoint defect on domain walls.

5研究了直流电场施加和撤除引起的钛锡酸钡顺电相场诱压电谐振慢弛豫现象，认为这是同极性空间电荷注入形成空间电荷慢偶极子导致的，观察到的负压电常数证实了这个观点；研究了等温条件下阶跃电压作用下介电常数和放电电流的慢弛豫现象，发现钛锡酸钡陶瓷的铁电相和顺电相呈现不同的宏观性能时间依赖规律，认为是同极性空间电荷的输运过程导致了顺电相样品呈现强的弛豫行为，铁电相中存在畴壁捕获空间电荷的机制因而其弛豫行为较弱；研究了钛锡酸钡陶瓷中束腰电滞回线、反常 C-V 曲线和顺时针可逆电滞回线等反常现象，将其归因于点缺陷的聚集对铁电畴畴壁的钉扎作用，多次电场循环有助于解除这种钉扎状态，减弱反常特征。

This kind of gratings can be kept in the material for a long time. A mode of molecular reorientation was used to explain the formation mechanism of these gratings and it is well consistent with our experimental results. 3. Three kinds of azobenzene polymers P , P (MMA-co-GY7) and P (MMA-co-GO13) were synthesized by radical polymerization. High-density optical storage and the three-dimension (3D) microstructures in the azobenzene polymer films were presented. Twenty gratings have been stored on the same spot in our material. It is twice as many as the best recording that has been reported. It is the first time, a rectangular microstructure and a complicated double layers nesting six-pointed star microstructure are inscribed in it by using a simple two-wave couple setup.

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。
