In this study, the fluidization behavior of SiO2 nano-particles and the effects of vibration parameters on size of agglomerates have been systematically investigated in a bed of 40 mm in diameter.

摘 要：在内径为40 mm的振动流化床中，以纳米级SiO2为实验物料，系统考察了振动参数对纳米颗粒流化行为和聚团尺寸的影响。

The results show that the concentration of displacement and stress in surrounding rock intensifies with the increase of excavation steps. The maximum compression and tension stress reach 54 MPa and 3.9 MPa, which are close to the peak strength of surrounding rock. When the tailings are backfilled, the magnitude of floor heaves reduces about by 5 mm, and the maximum compressive stress drops to 32 MPa. Distribution of both stress and displacement fields are improved and the stability of stopes can be ensured during the mining process.

研究结果表明：随着开挖逐步推进，围岩位移不断增大，应力集中现象明显，最大压应力达54 MPa，最大拉应力达3.9 MPa，接近围岩的极限强度；在尾砂回填后，底鼓量下降5 mm，最大压应力降至32 MPa，表明应力场和位移场均得到改善，能确保回采期间采场的稳定。

Calenders have becomed popular gifts because many are feeled with beautiful pictures.some have pictures are famous art-works.it is like handing differnt painting on the wall each month, you can even learn from calenders.they often give information about their subjects,such as famous writters or America Indians or flower gardens.there are calenders about food and about beautiful places in the world.calenders about sports and about movices,funny calenders with popular cartoon writters,calenders with famous people,like OP or MM.

日历已经成为一种流行的礼物，因为许多日历都印有许多漂亮的图片。一些日历的图片是著名的艺术作品。这就像在你的墙上，每月挂了不同的油画。你甚至可以从日历中学到东西。这些日历通常会显示出主题的信息—如著名的作家或者美国印第安人或花园。有关于食物、世界美景的日历。关于运动和电影的日历。关于流行卡通人物的趣味日历。以及有关于像OP或MM这样名人的日历。

After anaesthesia the rats were bled to a mean arterial pressure of （35±5） mm Hg for 60 minutes, and then the animals were resuscitated with 4 times the volume of withdrawn blood with lactated Ringer's solution over 60 minutes.

麻醉后通过放血的方法将平均动脉压降至（35±5） mm Hg，并维持60 min，然后在60 min内用4倍于最大失血量的乳酸林格氏液进行复苏。

The P-C-T curves for Ti_(0.17)Zr_(0.08)V_(0.35)- Cr_(0.1)Ni_(0.3) and Ti_(0.17)Zr_(0.08)V_(0.35)Cr_(0.1)Ni_(0.3)Mm_(0.01) alloys have been depicted by electrochemical methods. It is shown that as temperature rises, the hydrogen equilibrium pressure of the alloys goes up, but the hydrogen desorbing performance deteriorates. After addition of Mm, the hydrogen equilibrium pressure of the alloy comes down, and the hydrogen desorbing performance meliorates.

同时本文还通过电化学方法绘制了Ti_(0.17)Zr_(0.08)V_(0.35)Cr_(0.1)Ni_(0.3)和Ti_(0.17)Zr_(0.08)V_(0.35)Cr_(0.1)Ni_(0.3)Mm_(0.01)合金的P-C-T曲线，发现，温度上升时，Ti_(0.17)Zr_(0.08)V_(0.35)Cr_(0.1)Ni_(0.3)合金的平衡氢压上升，随温度上升，合金的放氢特性变差；添加Mm后，合金的平衡氢压降低，曲线的整体斜率变小，放氢平台宽度增大，说明合金的放氢特性得到改善。
