以野蔷薇为材料,提取内源多胺,用高效液相色谱法HPLC进行腐胺、亚精胺、精胺含量测定.结果表明,多胺提取过程中,样品用量0.2 g、冰浴浸提液300μL、苯甲酰化反应37℃,提取效率最高.HPLC检测参数:流动相为V(甲醇):V(水)(60:40),进样量15μL,流速1 mL·min-1,柱温30℃,检测波长254 nm,保留时间15 min时,3种内源多胺可完全分离并定量测定,相关系数均大于0.99,测定加标回收率为87.17％～103.64％,表明该方法可靠.在野蔷薇体细胞胚胎发生过程中,叶片培养3
Motivated by recent theoretical and experimental advances in quantum simulations using alkaline earth(AE) atoms,we put forward a proposal to detect the Kondo physics in a cold atomic system.It has been demonstrated that the intrinsic spin-exchange interac
以谷氨酸诱导PC12细胞为研究对象,分为对照组、模型组(谷氨酸处理)、天麻素组(天麻素、谷氨酸处理)、CD(香豆素衍生物)组(CD、谷氨酸处理)和联合组(CD、天麻素、谷氨酸处理),采用噻唑蓝法测定细胞存活率,由酶标仪检测细胞培养液中谷胱甘肽过氧化物酶、超氧化物歧化酶的活性和丙二醛的含量;Annexin V/PI染色经流式细胞仪检测细胞凋亡率.结果显示,CD(10.0μmol/L)联合天麻素(2.5μmol/L)对经谷氨酸处理的细胞存活率最高(高于模型组25.47％),谷胱甘肽过氧化物酶和超氧化物歧化酶的
The second law of thermodynamics dictates that heat simultaneously flows from the hot to cold bath on average.To go beyond this picture,a range of works in the past decade show that,other than the average dynamical heat flux determined by instantaneous th
Studying the complex quantum dynamics of interacting many-body systems is one of the most challeng-ing areas in modern physics.Here,we use machine learning (ML) models to identify the symmetrized base states of interacting Rydberg atoms of various atom nu
针对一类单链路机械臂系统,研究其基于事件触发机制的固定时间跟踪控制问题.通过引入事件触发机制和命令滤波器,提出一种基于Lyapunov函数的事件驱动固定时间控制策略,在降低系统计算量的同时,减小通信占用率.基于所设计的控制器,闭环系统的所有信号有界,输出信号可以在固定时间内跟踪到期望信号,且收敛时间与机械臂初始状态无关,同时跟踪误差可以收敛到平衡点邻近的任意小的区域内.最后,通过一个MATLAB仿真实例验证所提出的控制方案有较好的效果.
The photogalvanic effect (PGE) occurring in noncentrosymmetric materials enables the generation of a dc photocurrent at zero bias with a high polarization sensitivity,which makes it very attractive in photodetection.However,the magnitude of the PGE photoc
