Using ik algorithm can control the whole character by single bone , but nowadays the research mode of join animation combines forward kinematics with inverse kinematics because it is too complicated to only use ik 通过反运动学算法,可以仅使用单个骨骼控制整个角色产生动画,不过反向运动学算法比较复杂,所以当前研究方式是将正向运动学和反向运动学结合起来。
In the case of unexpected power - off incidents the main controlling chip can write ik byte words into a memorizer called at24c08 by i2c bus , thereforc the important parameters of the electric net period of time before the incident will be recorded 通过i ~ 2c总线主控芯片可将1k字节的数据写入at24c08存储器中，在掉电的情况下仍能保存一段时间内电网的重要运行参数。
The hierarchical structure of a pumping unit motion model is established by analyzing its motional rules , its 3d virtual simulation is implemented by using ik and used to the downhole operation simulation system , therefore better result is achieved 建立了抽油机关节运动模型的层次结构，实现了抽油机运动的三维仿真模拟；将其应用到井下作业仿真系统中，取得了良好的效果。
In the present study , using the conventional whole - cell mode and perforated whole - cell patch claxnp mode , the role of intracellular and extrce1lular calcium in snp - induced increase of ik ( . . ) were investigated . l 我们分别应用传统全细胞模式和穿孔模式的膜片钳技术，研究了细胞内外钙离于在s p诱导人h ）增加中的作用，进而阐明no引起豚鼠胃窦环行肌舒张的离子机制。
An approach of representing circular arcs with nurbs of degree two is presented in this paper and the central angle is between 0 and ik . a perfect law representing circular arcs with nurbs of degree three is presented 因此针对所有情况给出了用二次nurbs精确表示圆弧曲线的实用方法；基于李强等的工作指出有关文献中三次nurbs精确表示圆弧的算法的适用性限制，提出了用三次nurbs精确表示圆弧的一个改进算法。
Arsenal , who beat ume ? ik to become european champions eight days ago , fought back from conceding in the opening two minutes to defend the trophy they won against leeds united lfc last year thanks to two goals apiece from kelly smith and jayne ludlow 八天之前刚击败于默峰队成为欧洲冠军的阿森纳，感谢凯琳史密斯和洁恩勒德洛每人的两粒进球，她们在经历了开场两分钟的被动之后，继去年战胜利兹联队后卫冕该项冠军。
Over - activation of delayed - rectifier potassium channel , which leads to an augmentation of ik , is associated with the delayed neuronal death in ischemic / repefusion injury . so the inhibition of / k is maybe one of the mechanisms of vegf ' s neuroprotection effects I _ k在缺血神经元中是增强的，介导i _ k的钾通道的过度激活与缺血再灌脑损伤中的延迟性神经元死亡相关，因此抑制i _ k可能是vegf的缺血神经保护作用机制之一。
The character animation technology in 3d - graphic engine is deeply studied in this thesis ; it gives the implementation of articulated figure animation based on ik and skinned mesh character animation after analyzing the pluses and minuses of several character animation methods 在骨骼蒙皮动画的实现中运用了基于属性的网格优化技术和采用硬件支持的方式,并在此基础上给出利用现有的动画序列产生新动画的动画混合方法。
