为满足高温高矿化度油藏继续提高采收率的需求,室内以丙烯酰胺、2-丙烯酰胺-2-甲基丙磺酸、长碳链疏水单体和刚性单体为合成原料,制备了一种耐温抗盐型聚合物驱油剂KWY300,并对其综合性能进行了评价。结果表明,聚合物驱油剂KWY300具有良好的增黏性能和耐温抗盐性能,当溶液矿化度为133000 mg/L,老化温度为110℃时,质量浓度为1200 mg/L的聚合物溶液黏度值仍能达到80 mPa·s以上,增黏效果明显优于HPAM。聚合物驱油剂KWY300具有良好的渗流性能,在储层温度和矿化度条件下,阻力系数可以达到50以上,残余阻力系数约为10。此外,聚合物驱油剂KWY300还具有良好的驱油效果,注入PV数为0.5、质量浓度为1200 mg/L的KWY300溶液后,能使岩心水驱后的采收率继续提高16.4%,驱油效果明显优于HPAM。高温高矿化度油藏现场实施聚合物KWY300驱油措施后,区块内生产井的日产油量提升至措施前的3倍以上,含水率有所下降,起到了明显增油效果。

Herein,we report the design,fabrication,and performance of two wireless energy harvesting devices based on highly flexible graphene macroscopic films(FGMFs).We first demonstrate that benefiting from the high conductivity of up to 1×10^(6)S m^(-1)and good resistive stability of FGMFs even under extensive bending,the FGMFs-based rectifying circuit(GRC)exhibits good flexibility and RF-to-DC efficiency of 53%at 2.1 ***,we further expand the application of FGMFs to a flexible wideband monopole rectenna and a 2.45 GHz wearable rectenna for harvesting wireless *** wideband rectenna at various bending conditions produces a maximum conversion efficiency of 52%,46%,and 44%at the 5th Generation(5G)2.1 GHz,Industrial Long-Term Evolution(LTE)2.3 GHz,and Scientific Medical(ISM)2.45 GHz,respectively.A 2.45 GHz GRC is optimized and integrated with an AMC-backed wearable *** proposed 2.45 GHz wearable rectenna shows a maximum conversion efficiency of 55.7%.All the results indicate that the highly flexible graphene-film-based rectennas have great potential as a wireless power supplier for smart Internet of Things(loT)applications.

As a highly entangled quantum network, the duster state has the potential for greater information capacity and use in measurement-based quantum computation. Here, we report generating a continuous-variable quadripartite ＂square＂ cluster state of multiplexing orthogonal spatial modes in a single optical parametric amplifier （OPA）, and further improve the quality of entanglement by optimizing the pump profile. We produce multimode en- tanglement of two first-order Hermite-Gauss modes within one beam in a single multimode OPA and transform it into a duster state by phase correction. Furthermore, the pump-profile dependence of the entanglement of this state is explored. Compared with fundamental mode pumping, an enhancement of approximately 33% is achieved using the suitable pump-profile mode. Our approach is potentially scalable to multimode entanglement in the spatial domain. Such spatial duster states may contribute to future schemes in spatial quantum information processing.

EPR(Einstein-Podolsky-Rosen)导引展现出一种不同于量子纠缠态与Bell非局域性的量子非局域性,其中单向EPR导引在量子秘密共享中尤为重要。提出了一种通过在EPR纠缠态的一方增加噪声来改变EPR导引特性的方案,在引入噪声之后,分析了导引参数与可变分束器的反射率之间的关系,并研究了EPR导引的方向由双向到单向的改变过程。该研究对非对称的量子非局域性操控以及量子信息传递过程中的量子控制具有重要意义。

奥巴马第二任期基本上延续了第一任期内的对台政策,同时采取了一些新的措施,即在遵循美台非官方关系基本框架、确保避免冲击中美关系的前提下,给予台湾政治、军事、外交等方面的支持以稳固和发展美台关系,突出台湾在美国亚太"再平衡"战略中的重要作用,积极谋求对台湾问题的更多主动权。从近期来看,奥巴马政府对台政策调整仍在一定程度上维护了中美关系的大局、促进了两岸关系的发展,保障了东亚地区的安全稳定;但从长远来看,这些政策调整却蕴含着很多潜在的隐患和不确定性。
