Fourthly, this paper standardizes the linear of the inductance sensor and analyzes its error. Then we discuss the angle error of the laser sensor and the datum plane error of the mechanism.

第四， 此外，本文还对电感传感器进行了线性校正及误差分析，讨论了激光传感器倾角误差，并对机械设计中的定位结构进行了误差分析，提出了改进的措施。

At present, the main approach for seismic data imaging is the prestack Kirchhoff time migration, however, violent variation of surface elevation makes the datum plane selection of prestack time migration very difficult.

目前该类地区地震勘探中主要的成像手段依然是Kirchhoff叠前时间偏移。但地表高程的剧烈变化使叠前时间偏移的基准面很难选择。

Datum plane and side planer or milling machine in the processing; face away from the machine only needs a general cross-section.

平面和侧面的基准面可在平刨床或铣床上加工；端面一般只需要距机横截。

So far the pattern of seismic prestack depth migration is the same as it abroad. Before the work of velocity building the original seismic data must be corrected on a datum plane, and then to make the prestack depth migration work.

目前我国叠前深度偏移的研究方向与国外基本一致，特别是在目前油田的实际勘探中，大多套用国外的模式，一般都是对原始资料校正在一个基准面后，然后开展叠前深度偏移工作。

Many of the elements below each constraint element PRO_E_DTMPLN_CONSTRAINT are used only for certain constraint types, so any given datum plane may contain fewer elements than are shown in the tree.

许多下面每个约束元素 PRO_E_DTMPLN_CONSTRAINT 只使用确定的约束类型，所以任何给定的基准平面可能包含比树里看到的少些的元素。

Length datum: Symmetry plane or the end surface.

长度基准左右对称面或左端面

The system has avoided the traditional precision guiding rail needed by large area flatness measurement and established a high precision virtual datum plane in computer.

该系统摒弃了传统的大面积工件平面度测量所需要的高精度导轨等实物基准，而是通过在计算机中建立高精度的虚拟基准，达到了对太阳帆板平面度的高精度测量，并对这种特殊的仪器结构所造成的光斑特性进行了分析。

Average velocity: The distance traversed by a seismic wavelet divided by the time required, both often corrected to a reference datum plane.

平均速度：一个地震子波传播距离与所需时间的比值，其中距离和时间通常都被校正到一个参考基准面上。

Palaeogeomorphology is a main factor to control the development and distributing of the sedimentary facies like the geomorphology today which is affected by the factors such as the location of the area tectonics, weather, the change of the datum plane and the tectonics movements.

古地形地貌是控制一个盆地后期沉积相发育与分布的一个主要因素，同现在地貌一样，古地貌形态受到了所处的区域构造位置、气候、基准面变化及构造运动等因素综合作用的影响。

I didn't have enough datum at hand.

目前我的手头没有足够的资料。

Vishnu entered a dark fourth dimensional dream that did not support his field or continued life.

毗瑟挐进入了一个第四密度的黑暗梦想，那里并不支持他的能量场或继续生命。

Leaders and decision-making persons use it to collect the data, including the information of unit work, handing in fee, oweing fee, prepaying fee,changing and afterpaying and account transfering of joining-insurance employee, and account paying of all kinds of insurances from hospitalization insurance institutions.The collected data is picked up, organized, switched and showed to user.

该子系统主要面向各级领导、决策分析人员；从各个医疗保险经办机构和定点医疗机构采集数据，包括在各个医疗保险经办机构处理的单位办公信息，单位缴费、欠费、预缴费信息，参保职工变更信息，参保职工增减变动信息，参保职工补缴信息，参保职工帐户划拨信息：包括各定点医疗机构处理的各险种帐户支出信息，各险种的统筹金支付信息等；将采集的数据提取，组织和转换，然后展示给用户。
