The influences of plating bath solution ph and current density on coercivity of electroplating coNdNiMnp permanent magnetic film arrays were studied. The experiment results show that both for solution ph and current density there were the best depositing parameters. Too high and too low plating bath solution ph or current density both result in decreasing of the film array coercivity. when solution ph is 3.5 and current density is 5mA/cm2, the prepared film array coercivity can reach the maximum.

In order to improve the performances of electroplating permanent magnetic films, neodymium is introduced into the electroplating coNiMnp permanent magnetic films. The influences of the neodymium content are also investigated by varying Ndcl3 plating bath concentration. The neodymium-doped films are analyzed by energy dispersive spectrum (EDs), vibrating sample magnetometer (VsM) and magnetic force microscope (MFM). The experimental results show that high magnetic performances of coNdNiMnp permanent magnetic films with vertical anisotropy could be fabricated with current density 5mA/cm2 at room temperature. with the increasing of neodymium contents, the magnetic properties of films were improved. however when neodymium contents exceeded 3.5wt%, the magnetic properties of films are not improved any more. The increase of film magnetic properties results from the ferromagnetic-coupling between light rare earth element-neodymium and transition metal element-cobalt.

Using e^(+)e^(−)annihilation data corresponding to an integrated luminosity of 2.93 fb^(−1)taken at the center-of-mass energy√s=3.773 GeV with the bEsIII detector,a joint amplitude analysis is performed on the decays D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η).The fit fractions of individual components are obtained,and large interferences among the dominant components of the decays D^(0)→a_(1)(1260)π,D^(0)→π(1300)π,D^(0)→ρ(770)ρ(770),and D^(0)→2(ππ)_(s)are observed in both *** the obtained amplitude model,the cp-even fractions of D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η)are determined to be(75.2±1.1_(stat).±1.5_(syst.))%and(68.9±1.5_(stat).±2.4_(syst.))%,*** branching fractions of D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η)are measured to be(0.688±0.010_(stat.)±0.010_(syst.))%and(0.951±0.025_(stat.)±0.021_(syst.))%,*** amplitude analysis provides an important model for the binning strategy in measuring the strong phase parameters of D^(0)→4πwhen used to determine the cKM angleγ(ϕ_(3))via the b^(−)→DK^(−)decay.

目的通过有限元分析研究不同空心螺钉内固定方式在sanders Ⅱb型跟骨骨折的生物力学稳定性。方法在一名志愿者(男性,26岁,身高173 cm,体重70 kg)跟骨cT基础上,通过Mimics 22.0、Geomagic12.0、solidworks2019、ANsYs workbench 2022等数字医学软件建立跟骨三维有限元模型,建立sandres Ⅱb型跟骨骨折模型。螺钉分为以下3种:①纵螺钉:自跟骨结节向前部;②横螺钉:自跟骨外侧壁向载距突;③垂直螺钉:自跟骨底部向丘部,垂直于后关节面。螺钉配置方案如下:纵螺钉自跟骨结节上方、中部、下方为进钉点分为上方组、中部组、下方组,再依据双横螺钉+单垂直螺钉、单横螺钉+单垂直螺钉、双横螺钉+无垂直螺钉和单横螺钉+无垂直螺钉的配置方式进一步分为4个亚组,最终得到12个模型(a、b、c、d、e、f、g、h、i、j、k、l模型)。在后距关节面和中距关节面分别施加420 N和200 N载荷模拟成人单足站立时跟骨受力,分析各个模型的总形变位移,丘部、前部、关节面骨折裂缝相对位移,骨折断端、螺钉的应力峰值。结果i、j模型的总形变位移最低,k、l模型的形变位移最高;其余模型的最大形变位移变化幅度较小。丘部骨折裂缝平均相对位移在上方组最低(0.27 mm),下方组相对较高,其中k、l模型的变异最大;前部骨折裂缝平均相对位移在下方组最小(0.16 mm),其中i、k模型表现最佳;关节面骨折裂缝相对位移在所有模型中均保持在较低水平。上方组模型骨折断端平均应力峰值最低(60.20 Mpa),中部组和下方组接近(分别为103.88 Mpa和99.76 Mpa)。上方组的螺钉平均应力峰值最小(222.77 Mpa),下方组k、l模型的平均应力峰值最高,分别达到331.48、349.82 Mpa。结论i模型(下置纵螺钉+双横螺钉+单垂直螺钉)在降低总形变位移和前部骨折裂缝相对位移方面具有优势,值得推荐。纵螺钉、垂直螺钉和横螺钉在跟骨骨折固定中承担着不同作用,医生可根据患者需求选择适宜的螺钉配置。
