Bezier curve, which is intuitive and easy to control, is employed in the trajectory planning to generate the interpolation points, which need good accuracy and stability of velocity in Cartesian space.
贝塞尔曲线是一种直观并且易于控制的曲线,在轨迹规划研究中被用来生成插值点,生成插值点需要在笛卡尔空间中,速度具有好的精度和稳定性。

第三天:In the single mode fiber lasers, owing to the core and clad configuration, any light wave other than that of core guided modes in the employed fiber is difficult to be trasmitted, so that the output light forms stable transvers modes in accordance with the index profile.

第三天:Experimental Materials. The raw materials included UO2(NO3)2·6H2O, (NH4)2CO3, CH3C(NH2) (NOH) (re- ferred to as AO), and Milli-Q water with a conductivity of 18.2 MΩ cm?1. First, we prepared a solid (NH4)4UO2(CO3)3 sample. Then, UO2(NO3)2·6H2O (0.007 mol) was directly dissolved in a specific amount of deionized water. Subsequently, (NH4)2CO3 aqueous solutions (0.12 mol) were slowly added into the uranyl nitrate solution. The yellow precipitate was isolated by centrifugation and collected after drying. To prepare a uranyl carbonate solution, (NH4)4UO2(CO3)3 powder was directly dissolved in deionized water with pH 8.16. To prepare uranyl?AO/CO32? solutions, a desired concentration of an

So, while the minimum particle width must still be larger than r ∗, the maximum size (length of rod) is limited by both surface diffusion of the nanoparticle component species along a/bYBCO and bulk
diffusion downwards along c, the latter being impeded by the continuous addition of YBCO layers to the growing film.当某现象发生时,另一种现象会出现其他情况,并且后者会、、、

4/7: It is known thatthe electrochemical impedance spectroscopy (EIS) is a powerful tool and a noninvasive technique to investigate the electrochemical processes, such as the properties of multilayer
systems and its complicated surface, the rate of electrochemical reactions, dielectric and transport properties of materials and so on.
努力找方向!
