This present algorithm further distinguishes itself through sufficiently utilizes the advantage that the vector sensors provide from other beam space DOA algorithms in several regards: 1 beams are formed in the vector-field domain; 2 produce at moderate signal-to-noise ratio estimation performance comparable to the traditional scale array methods;3 these vector-field beams are formed blindly using no apriori source information and coarse estimates of the direction cosine are derived to start off MUSICs iterative search so it demand less computation; 4 deploy agilely , since the fact that the output channel is various .

本文提出了矢量传感器阵列的自适应综合校准补偿方法，还提出利用单矢量传感器速度协方差矩阵分解来求解目标源方位，使得我们不要求校准源是合作性的，也无需知道校准源的先验知识，这比起常规辅助源校准方法具备较大宽容性。随着高性能阵列处理技术及数字信号处理硬件的快速发展和矢量传感器制造工艺的不断成熟，矢量传感器将在新型水雷、低频远程智能鱼雷、声纳浮标、低频拖曳线列阵和新型舰壳声纳，灵巧传感终端，战场监视系统，反隐形雷达，通讯等军民用领域取得良好的发展应用前景。

It is pointed out that the error of indication E0 for the calibrated test length which are measured when the offset length between the ram axis and the stylus tip is zero shall neither exceed the maximum permissible error MPEE0 nor exceed 1/3 of the probe error,that the repeatability of E0 shall neither exceed the maximum permissible error MPE Rnor exceed the repeatability error of the probe,and that if the measuring data is rejected in acceptance and reverification,measurement must be carried at least 5 times at the same position for reducing the possibility of misjudgement.

提出探测轴探针针头零偏置长度的校准测试长度的示值误差E0应不超过最大允许校准测试长度的示值误差MPEE0，且不应超过测头误差的1/3；E0的重复性误差R不应超过最大允许重复性误差MPER，且不应超过测头的重复性误差。建议验收校准测量数据超差剔除后，必须在相应位置重复测量5次以上，以减小误判的可能性。

本文介绍了一种脉搏式血氧饱和度仪校准仪的研制，这种校准仪可以检测血氧仪的工作状态是否正常，并能对血氧仪的输出参数进行校准。

It's pointed out that in the design of a weapon system, a collimating prism box should be installed behind the electro-optical instrument, if the condition is permitted, to control the electro-reticule generator or other functional elements added in the circuit, and make the weapon system realize the automatic collimation during flighting or driving.

指出在武器系统的设计中，如果条件允许，可在光电仪器的后方设置一个校准棱镜箱(或折反式自准凹面镜组件)，以便在控制电路中加入电十字线跟踪产生器等功能单元，使武器系统实现行进间或飞行中自动校准。标签光电仪器光轴自动校准 electro-optic instrument light axis auto-collimation

The calibration samples were prepared by adding standard solution into spectroscopically pure TiO2, guaranteeing the accuracy of each microelement content in calibration sample.

校准样品采用光谱纯TiO2中加入标准溶液的方法配制，保证了校准样品中各微量元素含量的准确性，采用理论α影响系数法校正基体效应，并对测量条件、熔剂选择、校准样品配制、方法扩展等进行了探讨。

Pressure figures from this ISA are used in calibration of barographs, because although the real atmosphere varies from day to day, for calibration purposes a set of internationally agreed figures are needed so that all calibrations are to the same datum, whether or not such figures correspond to 'true' height on a given day.

来自 ISA 的压力数字，用来校准自动记录式气压计﹙ barographs ﹚，因为真正的大气每一天都不同。为校准的目的，需要一套国际同意的数字是，使所有校准是相同的基准，无论这些数字是否对应某一天的'真正的'高度﹙ 'true' height ﹚。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
