A differential demodulation system of Laser Doppler is designed. Phase grating is adopt to obtain same intensity measured beams with big separative angle in the system,and by focusing the waists of two Gauss beams on the measured object with extender and collimating lens group, the smallest speckle and the superposition of plane waves are obtained.

Its level set methods are investigated in detail, and a fast initialization method for level set based on the threshold over interframe difference is proposed.

正是由于测地线主动轮廓模型的这些优点，我们对它的Level Set方法进行了研究，提出了基于帧间差的快速Level Set初始化算法。

In this research we increased the backsights from 3 to 10 points.and observed 5 sets of VRS,1 set of static GPS,5 sets of 3D LASER. we considered the Static GPS as the standard observation set,and compared it with the VRS's coordinates after adjustment.The RMS and the range of differences are taken as the indicator of accuracy .

一般而言，3D LASER作业只须三个已知点即可定得绝对坐标，为了增加多余观测量，本研究将3个后视点增加为10个后视点，针对这10个后视点分别施测5组VRS、1组静态GPS、及5组3D LASER，文中以静态GPS为对照组，以改正前后之VRS坐标与静态GPS坐标较差之RMS及分布范围为精度分析之指标。

The post-process employed the etchants to etch the sacrificial layers, and to release the suspended structures, and then used a PDS to seal the etching holes in the pressure sensors.

制程完成后利用蚀刻液，以湿式蚀刻方式，将压力薄膜结构释放悬浮，并且使用化学沈积系统沈积高分子材料parylene，将压力空腔封装，以量测外界与压力腔的压差。

But the film of the appearing developer、Fixer conditions it is difficult to guarantee the stability of, so the comparison of stringent practice, every day for sampling of linearation.

但胶片不隐影、不退影前提的安不退性很难包管，因此比力不苛的怠工法是，每天都差线性化举行抽测。

This technique is to make a device to instead those transmitters and reduce the need in pressure gauges. Using the electronic valve and flexible tube to construct the control panel is effective to connect the single pressure gauge with every sensor point in ventilation duct.

利用软管将欲量测之管段的压力导引到控制箱内，并将所有导引来的静压分别安装在一组并联的各电磁阀上，再将所有的动压分别安装在另一组并联的各电磁阀上，而该两组并联电磁阀的底部各安装一根连通管连结至单一差压计的高低压两端，并利用控制组件切换各电磁阀的启闭以达到多点压力监测切换的目的。

Muti antennae GPS/Gyro integrated navigation system is studied too in this paper. Using single difference GPS carrier phase observations and quaternion error, state equation and measurement equation is established for muti antennae GPS/Gyro integrated navigation system.

本文也对多天线GPS/Gyro组合捷联航姿系统进行了研究，利用单差载波相位测量的方法，建立了基于四元数误差的多天线GPS与Gyro组合航姿系统的状态方程和量测方程。

First, we adopt MEMS technology to fabricate micro venturis with different widths of 150 and 200 um respectively and utilize FLUENT software to analyze the flow fields. Air was set as the working fluid and the air mass flow rate of inlet is changed to obtain the pressure drop between inlet and outlet. When a flow passes through the throat, the backflow results in the symmetric separations occur and grow with the increase of mass flow rate.

在微文氏管的研究部分，首先利用微机电制程技术制造出两种不同尺寸的微文氏管，宽度分别为150及200微米，开口角度各为45°，总长则为10 mm，再以空气作为工作流体，利用不同质量流率来量测微文氏管进出口的压力差并配合FLUENT软体分析观察其流场分布的情况。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
