理论上提出了一种通过调节双环混合偏振矢量光束的偏振态来实现光学囚笼实时操纵的新方法。双环混合偏振矢量光束是由双环径向光束通过一个波片后形成的,光束偏振将变为包含线偏振、圆偏振和椭圆偏振的混合状态,且偏振态强烈依赖于空间位置和相位延迟角度。利用衍射积分公式数值模拟了双环混合偏振矢量光束经过强聚焦系统后在焦点附近的强度分布。数值结果显示当相位延迟角度为0时能形成光学囚笼,当相位延迟角度不为0时能控制光学囚笼打开的程度。将液晶可调相位延迟器（LCVR）作为可调波片,LCVR可以由外部电压实时控制使其相位延迟角度能在0～π之间连续取值,这样就可以通过调节LCVR的外接电压实现焦平面光学囚笼的实时开和关。

Based on the annual data from 1987 to 2010, using ADL regression model ideas and the concept of lagging effect. AIC,SC information criterion are used as selecting optimal lag order number of the judgment standard, In order to estimate and calculate the lagged-time about FDI,R＆D and the technological innovation variables. The result shows that FDI has no significant impact on the promotion of technological innovation capability, there exists a negative spillover effect to our core technological innovation capability, FDI can not bring about the substantive upgrade of China＇ s core technological innovation capability. At the same time, study on the two groups of data, shows that the not significant in- fluence in the period from 1987 to 1998 evolved into significant influence in the period from 1999 to 2010 , and the re-sult is mainly due to the strengthen effect of China＇ s independent innovation to the impact of FDI. But FDI created＂ex- trusional effect＂and the＂ substitutional effect＂ to the ability of R＆D innovation.
