When the CORER penetrates the ocean bottom the stopped cable and piston, in effect, provides a suction which overcomes the frictional forces acting between the SEDIMENT and the interior wall of the coring tube.	采样管内装有活塞的一种采样器，它连接在一根下降的缆绳上。当采样器穿入海底时，停止下降的缆绳和活塞实际上产生一种吸引力来克服作用在沉积物和取样管内壁之间的摩擦力。
	corer: polyvinyl	聚乙烯取芯（采样）器	See CORER: HYDROPLASTIC.	参见hydroplastic corer（氢化塑料取芯器）。
	core sample	岩芯样品	See CORE.	参见core（岩芯）。
	coring instrument (or device)	取芯仪	See CORER.	参见Corer（采样管，取样管）。
	coring (or core) tube	采样管	See CORE BARREL.	参见core barrel（采样管）。
	Coriolis force	科里奥利力	Composite CENTRIFUGAL FORCE, due to the ROTATION of the EARTH, which acts on moving particles, whose motion is considered relative to that o... more Composite CENTRIFUGAL FORCE, due to the ROTATION of the EARTH, which acts on moving particles, whose motion is considered relative to that of the EARTH.	由于地球旋转产生的作用于相对地球运动物体上的复合离心力。
	corona	日冕，华，光环	PHOTOMETEOR formed by one or more sequences (seldom more than three) of coloured rings of relatively small radius, centred on the SUN or MOO... more PHOTOMETEOR formed by one or more sequences (seldom more than three) of coloured rings of relatively small radius, centred on the SUN or MOON.	一种大气现象。在日、月周围形成一层或多层（很少超过三层）半径相当小的彩色光环。
	corrected establishment	平均朔望高潮间隙	See LUNITIDAL INTERVAL.	参见lunitidal interval（月潮间隙）。
	correction	改正，校正，修正，改正量	A quantity which is applied to an OBSERVATION or function thereof, to diminish or eliminate the effects of ERRORS and obtain an improved val... more A quantity which is applied to an OBSERVATION or function thereof, to diminish or eliminate the effects of ERRORS and obtain an improved value of the OBSERVATION or function. It is also applied to reduce an OBSERVATION to some arbitrary STANDARD. The correction corresponding to a given ERROR is of the same magnitude but of opposite sign. See CHRONOMETER CORRECTION, DIP CORRECTION, INDEX CORRECTION, INSTRUMENTAL CORRECTION, LEAD LINE CORRECTION, PARALLAX CORRECTION, PERSONAL CORRECTION, POLARIS CORRECTION, REFRACTION CORRECTION, SEMIDIAMETER CORRECTION, SEXTANT ALTITUDE CORRECTION, SKY WAVE CORRECTION, ORTHOMETRIC CORRECTION, TIDAL DIFFERENCE.	为了减小或消除观测或操作的误差影响并获得更精确的结果所应用的一种改正量。利用这种改正值可将观测结果化算成某种任意标准。改正量应与已知误差相对应，其大小相等，符号相反。参见chronometer correction（天文钟改正量）、dip correction（倾角改正）、ind... more 为了减小或消除观测或操作的误差影响并获得更精确的结果所应用的一种改正量。利用这种改正值可将观测结果化算成某种任意标准。改正量应与已知误差相对应，其大小相等，符号相反。参见chronometer correction（天文钟改正量）、dip correction（倾角改正）、index correction（指标差改正）、instrumental correction（仪器改正）、lead line correction（测深索改正）、parallax correction（视差改正）、personal correction（人差改正）、polaris correction（北极星改正）、refraction correction（折射改正）、semidiameter correction（视半径改正）、sextant altitude correction（六分仪高度改正）、sky wave correction（天波改正）、orthometric correction（正高改正）、tidal difference（潮汐改正数）。
	correction: atmospheric	大气改正	The statistical removal of meteorological effects from mean sea level changes.	从平均海平面变化中去除气象因素的影响。
	correction: ionospheric	电离层改正	A correction for errors introduced by ionospheric refraction occurring when signals travel through the ionosphere.	对信号通过电离层时由于电离层折射所产生的误差的改正。
	correction: relativistic	相对论性改正	A correction for errors introduced by relativistic effects of the clock rates of positioning systems.	定位系统时钟速率的相对论效应所引起的误差改正。
	correction: sky-wave	天波校正	The correction to be applied to the signals received via the ionosphere to convert them to their groundwave equivalent.	加在天波接收时间差上的校正。即把天波接收信号读数转变为等值的地波读数的校正。

	correlate equation	联系数方程	See EQUATION: CORRELATE.	由观测方程或条件方程导出的一种方程。其导出方法是：使用不定因子，将不定因子引入观测方程或条件方程中，然后求出由这些方程所得剩余误差的平方和为最小时的条件表达式。
	correlation	相关性	The removal of discrepancies that may exist among survey data, so that all parts are interrelated without apparent error.	去除测量数据之间可能存在的差异，以确保所有的部分相互关联而没有明显误差。
	correspondence	符合，一致	In STEREOSCOPY, the condition that exists when corresponding IMAGES on a pair of PHOTOGRAPHS lie in the same EPIPOLAR PLANE; the absence of ... more In STEREOSCOPY, the condition that exists when corresponding IMAGES on a pair of PHOTOGRAPHS lie in the same EPIPOLAR PLANE; the absence of Y-PARALLAX.	在立体观测法中，指像对上对应的图像处于同一核面上，无上下视差。
