The accuracy of 3 - d surface - shape measurement by phase - measuring profilometry ( pmp ) is greatly influenced , because the variation of environmental light leads to biggish error 摘要在运用相位测量剖面术( pmp )对物体进行三维面形测量时，由于测量现场环境光强变化而引入较大误差，严重影响测量精度。
Ds - m dsp frequency feedback controller is made of dsp shift frequency and dsp automatism digital filter . dsp software searches howl point and lock it by locale condition , with no adjusting Dsp数字移频反馈控制器，由dsp数字移频- dsp自动数字滤波器组成，根据现场环境dsp软件自动寻找啸叫点并锁定，无需人工调节。
The hong kong police and transport department will make contingent traffic arrangements according to prevailing circumstances . the special arrangements will be announced via appropriate means to inform members of public 警方及运输署会按现场环境而即时作出应变，并透过电台及电视台向公众发布有关的信息，让市民知悉。
Environment of modern in - situ vibration measurement has become more complex , measurement points increased and the measurement range widened greatly with the coming forth of long , large , tall and flexile structures 随着长大高柔结构建筑的不断涌现，现代振动测试现场环境更为复杂、测点布设数量更多、测点分布范围更广。
This method will improve the original control system , is suitable for the separate field , and accord with the new demand to the monitoring system , such as highly integration , information , and network 该方式将改善传统的监控系统存在的弊病，适合于分散的现场环境，并且符合控制系统高度集成化、信息化和网络化对监控系统提出的新的要求。
Public are reminded that the section of sai kung man yee road will be congested due to a large number of race participants . taxis may not be allowed to enter the pak tam chung barrier when the traffic conditions are not allowed 警方提醒市民，由于参赛者人数众多，预计西贡万宜路届时会比较挤塞，警方可能会鉴于现场环境，不允许的士驶入北潭涌道路管制闸口。
He snapped at the crowd telling them not to enter the park because it is haunted by ghosts . the crowd doesn t believe what the watchman said . they decide to sneak into the park after dark 众人认为看更所说祗是危言耸听，入夜后决定再次偷入游乐场，怪事亦随即发生拿著dv机拍摄现场环境的家豪，当发现有类似鬼火的物体出现画正内，他被吓得不断逃跑，不知不觉的来到鬼屋内。
In the fieldwork of industry , many disadvantages , such as abominable environment , unbalancing illumination , displacement of carried products , etc . . will cause that the obtained images are fuzzy , noisy or will bring characters into scaling , shift and rotation 由于工业现场环境恶劣，光照不均，传送过程中产品可能发生移动，诸多不利因素会引起所拍摄的图像失真、模糊、含噪以及使字符产生缩放、平移和旋转的情况。
This monitor provides convenient on - the - spot environmental control as well as local or remote timely monitor and examination of the history data through a computer , hence the scientific basis for the management of environmental protection departments and for the total amount control of pollutant discharge 该仪表既方便用户现场环境监控，又可通过pc机在本地或远方进行实时监控和查看历史记录数据，为环保部门的管理及排污总量控制提供科学的依据。
Because period narrow band signals are the main part of background noises , this thesis uses hardware description language to design a multi - band finite impulse response filter ( fir ) and downloads the program into filed programmable gate array to eliminate the period narrow - band interferences in the background noises 3 )在现场环境中，背景干扰主要是周期性的窄带，本文利用硬件描述语言( vhdl )设计了一个多带fir有限冲击响应滤波器。应用到可编程逻辑器件中，消除了背景噪声中的周期性干扰，为信号的进一步处理提供尽可能干净的信号。
