为进一步尝试采油的新技术,研究了声波、涡流对流体的影响,V选择了鄯善采油厂和中原油田采油一厂油井作为试验井.结果表明,在声波涡量的综合作用下,可以使垢层破裂、滑脱,使原油质点从吸附状态变为游离状态,使油、水的渗流速度和渗流量提高,最终使产液中的液、气、固三相高度溶融并乳化,从而起到防腊、防垢、降黏、增油的作用.分析了现场的试验数据,表明实现了明显的节能效果,有效延长了加药清蜡周期,运行安全可靠,对油层无伤害,对岩层无污染,提高了原油的采收率.

以MgAC2为掺杂源,采用固相反应法在惰性气氛下合成了掺Mg的LiFePO4正极材料,考察了Mg2+对于目标化合物物理及电化学性能的影响。采用粉末X射线衍射和扫描电镜技术对产物的结构、形貌及粒度等进行了表征,通过恒电流充放电和交流阻抗技术对其电化学性能进行了研究。结果表明:少量的Mg2+掺杂并未影响产物结构,但却有利于减小LiFePO4电荷转移过程中的阻抗,克服该过程中的动力学限制。在0.1C倍率下放电,掺杂LiFePO4与未掺杂LiFePO4的初始放电容量分别为136.9和111.8 mA.h/g,循环50次后,容量分别为135.6和83.9 mA.h/g;与未掺杂的LiFePO4相比,掺镁后的LiFePO4具有更为优良的循环性能。

We proposed a lattice Boltzmann model for the Rossler equation. Using a method of multiscales in the lattice Boltzmann model, we get the ditheion reaction as a special case. If the diffusion effect disappeared, we can obtain the lattice Boltzmann solution of the Rossler equation on the mesescopic scale. The numericale results show the method can be used to simulate Rossler equation.

Objective To identify the pathogenic variant responsible for restrictive cardiomyopathy （RCM） in aChinese *** Next generation sequencing was used for detecting the mutation and results verified bysequencing. We used restriction enzyme digestion to test the mutation in the family members and 200 unrelatednormal subjects without any cardiac inherited diseases when the mutation was *** Five individuals died from cardiac diseases, two of whom suffered from sudden cardiacdeath. Two individuals have suffered from chronic cardiac disorders. Mutation analysis revealed a novelmissense mutation in exon 7 of troponin I type 3 （TNNI3）, resulting in substitution of serine （S） withproline （P） at amino acid position 150, which cosegregated with the disease in the family, which is predictedto be probably damaging using PolyPhen-2. The mutation was not detected in the 200 unrelated subjectswe *** Using next generation sequencing, which has very recently been shown to be successfulin identifying novel causative mutations of rare Mendelian disorders, we found a novel mutation of TNNI3 in aChinese family with RCM.
