The best way to understand what this means is to see how an sif contract can be used by the investor to profit from his views on broad market movements 要了解股价指数期货，最简单的方法还是先看它身为投机工具的一面：股价指数期货是以约定的股价指数涨跌幅度来决定输赢大小的一个工具。
After that , we give another research on the successful design of sif contract . on the base of it , we design our own sif contract with chinese characteristics 之后对国际上成功的股指期货合约进行了比较研究，在此基础上就目前我国金融市场状况设计出一份符合中国特色的股指期货合约。
3 . from the view of current conditions , whether sif itself , or government departments , or market , all are lack of correspondingly theoretical recognition and institute foundation 3 、从当前现实条件来看，无论是社保基金本身，还是政府部门、市场方面都还缺乏相应的理论认识和制度基础。
The time in which the security industry of our country develops greatly is coming , but industrial conduct criterion must be erected first along with the growth of the quantity and the scale of sifs 我国基金业的大发展时代即将来临，但随着基金数量和规模的增长，行业行为规范必须先行确立。
The stress intensity factor ( sif ) and the strain energy release rate were simulated with different pre - crack length for the cases with no - flow underfill and with capillary - flow underfill 本文第六章用断裂力学方涪和有限元模拟分析了填充不流动胶芯片断裂问题，计算了芯片的应力强度因于k和能量释放率g 。
A global crack - line displacement fitting procedure ( gcdfp ) for computing stress intensity factors ( sif ) has been developed . the precision of sif is compatible with the corresponding cod data 使用paris公式求出裂纹前缘各点的裂纹扩展增量，并用三次b -样条函数对这些增量进行拟合，得到新的光滑裂纹前缘。
This combination of high - quality codec and high - speed network support provides video quality comparable to standard tv broadcasts . the pcs - g50p supports a maximum of 50 fields per second in interlaced sif format 这一高品质编码器和高速度网络支援的集成使得系统可为用户提供能够与标准电视广播相约的视频品质
In the material of fgh95 containing al2o3 inclusions , broken inclusion and debonded interface decrease the value of sif comparing with that of the same size crack without inclusions 结果表明，对于含al _ 2o _ 3夹杂的fgh95粉末高温合金材料，当夹杂裂开或界面脱开时，应力强度因子均小于将夹杂视为初始裂纹时的应力强度因子。
To echo the theme of the fair , the sif forum will be held from november to december , focusing on " information & industrialization " and will include 11 professional symposiums and five subject seminars 展会之后上海国际工业展将于11月至12月举办以”信息产业化”为主题的研讨会,这其中包括11个专业主题研讨会和5个课题研究会
The main contents are as following : ( 1 ) finite element method ( fem ) is used to study the effects of broken inclusion and debonded interface on the stress intensity factors ( sif ) 本文围绕含夹杂粉末高温合金涡轮盘的裂纹扩展寿命问题，开展了以下工作： ( 1 )用有限元法研究了夹杂裂开以及夹杂与基体界面脱开对应力强度因子的影响。
