Firstly, the stope vacancy was monitored using CMS, taking cavity measured data as foundation, cavity three-dimensional model of the stope opening was created using Surpac software and gain the stope three-dimensional configuration and the actual boundary accurately. Then, the stope designed model and ore-rock interface digital terrain model were established according to the stope design material. Finally, using ore-rock interface DTM to cut cavity model or through Boolean calculation among the models, ore remains, mining total volume, mullock, backfilling, pure ore and dilution rate of stope N3-4 were calculated accurately, thus the large-scale stope mining index visible calculation was realized effectively.

Everyday besides have a meal to sleep even if get online, resemble of course I can give the door on the weekend, like to go out very much before me journey but time is closer now, hardly what sky goes out, bar also did not go, KTV gets collect to just fall to poll, the most place that goes possibly is cinema and odeum, also often a person goes, feel to be done from personal pretty laugh, nevertheless a desire wants to issue Sichuan namely now, because oneself aided financially a few children to read in a few years, this year Sichuan elementary school of a child there graduated quickly, I want to see him namely, but according to present condition for, do not know to be able to be met really give time to go for nothing.

天天除了吃饭睡觉就是上网，当然像周末我会出一下门，我以前很喜欢出门旅行但是现在时间比较紧，几乎没什么空出去，酒吧也不去了，KTV得凑到人头才去下，可能去的最多的地方就是电影院和音乐厅，也经常是一个人去的，觉得自己蛮搞笑的，不过现在有个愿望就是想去下四川，因为几年里自己资助了几个孩子读书，今年四川那边一个孩子小学就快毕业了，我就是想去看下他，可按照现在的状态来说，不知道会不会真会空出时间来过去了。

The instantaneous SNRof the receiver of STBC over raying fading is illustrated, based on this, the closed impression of STBC's symbol error rate is educed with M-PSK and M-QAM modulation and also presents the numerical results.

Through 2D axial symmetrical and 3D scarfed reversal nozzle calculating, the main flowfield characters were given, and compared with the experiment data for validation. Then, the program was given, which can well predict the performance of the scarfed reversal nozzle. In this paper, the flowfields of open cavities with different structures and different parameters were calculated. Some new, full and more reasonable mechanism interprets were given. We think that the essential cause of pressure oscillatory is coherent effect of wave, eddy and cavity structure, but the procedure is different with different cavity structure, it can not use single procedure to described.

通过对二维轴对称和三维斜切反喷管的计算分析，本文给出了流场的主要特征，并采用实验数据进行了验证，形成了分析斜切反喷管可靠的应用方法；本文通过对不同结构形式、不同参数的二维、三维非定常超声速开式空腔流动进行的计算分析，提出了较为全面、合理的空腔压力振荡循环机理的解释，本文认为压力脉动本质上是波、涡以及结构之间相互的干扰和耦合，但干扰的具体过程随空腔结构的不同差别较大，不能采用单一的规律进行描述。

For the security market with restricted borrowing and short sale unallowed, Options pricing formula are advanced, and the relation between them and Black-Scholes Options pricing formula is discussed.
