Do note that if you replace crt type displays on your reception counter with flat panels , consider viewing angles , the working position of staff , and how to maintain eye contact with guests 当用平板显示器取代传统的阴极显像管显示器时，要考虑显示器的视角、员工的工作位置以及员工怎样保持同顾客的目光交流。
Owing to the operating principle of the ground system and different working position of every spare parts , the operating frequency of different parts in the system influent the shell of the decelerator , electrical machinery baseplate and supporting differently 依据螺杆泵地面驱动系统的工作原理和各零部件的工作位置,系统内的运动部件的工作频率对减速器壳体、电机底板和支架的影响程度不同。
The comparison of the computational results of flap movements indicates that three operational positions of the wing flaps guided through the different tracks are nearly close to each other and the non - arc - track is better to guide the flaps to the original three positions exactly 计算结果表明，不同的轨道下所得的襟翼3个工作位置从几何角度看比较接近，其中非圆弧轨道能够使襟翼在3个工作位置与预先设计的姿态完全相同。
For specified three work positions as design inputs , the thesis evaluates their geometrical movements of the prime and sub - flaps , and some reasonableness are shown in view of kinematical geometry . the work can provide further aerodynamic analysis with variable wing geometrical data 以三缝襟翼的3个假定的工作位置作为设计输入，算出了3种不同轨道下襟翼的运动结果，并从几何角度进行了简单对比分析，为进一步的气动分析提供输入数据。
Design the software of compton back - scattering imaging scanner , point out the functions of this software . give out the program modules in which the directory and contents of this software is included . give out the interfaces of the main program modules and describe the meanings of operating elements on these program interfaces briefly 指明了本应用软件的功能，主要是控制三维扫描运动和源的工作位置、数据采集和处理以及文件管理和帮助等;给出了程序结构模块，从中列出了软件所含的主要目录;给出了几个主要的程序模块的界面，简要说明了界面中各操作对象的含义。
In this article the aerial working platform of straight - arm mode is mainly studied on the basis of analytical mechanics , namely the system is described with lagrange equations and a mathematical model is built . then a certain aerial working platform is analyzed and some conclusions have been drawn that the effects on vibration when correlated parameters are changed 并针对具体实例，讨论了各个参数在系统整体摆动中对臂架头部，即操作人员的工作位置处振动的影响程度，及一些随着参数值的变化，振动幅度的变化规律。
Marian had somehow heard that tess was separated from her husband - probably through izz huett - and the good - natured and now tippling girl , deeming tess in trouble , had hastened to notify to her former friend that she herself had gone to this upland spot after leaving the dairy , and would like to see her there , where there was room for other hands , if it was really true that she worked again as of old 玛丽安不知道怎么知道了她已经同丈夫分居了大概是从伊茨休特那儿听说的这个好心的喝上了酒的姑娘，以为苔丝陷入了困境，就急忙写信给她从前的这位老朋友，告诉她的老朋友，说她离开奶牛场后就到了这个高原农场上，如果她真的还是像从前一样出来工作的话，那儿还有几个工作位置，希望能在那个农场上同她见面。
