They may be caused by the motion of the vessel through the water, by acoustic or electric NOISES in the ship, or by electric NOISES in the echo sounding equipment. Strays may be mistaken for the true echo or may be of such a nature as to prevent the identification of the true echo.	在回声测深中，常常显示在回声测深仪刻度盘或回声图上的假信号。这些假信号产生于船只通过水体的运动，或船体的声、电噪声，或回声测深设备的电噪声。杂声或许被误认为真回声信号，从而妨碍真回声信号的辨认。

A steady CURRENT in the SEA or in a RIVER, especially the middle or most rapid part of a TIDE or CURRENT. A steady FLOW of a fluid, small solid particles, or RADIANT ENERGY.	向船外投放并固定某物，如掷测程仪，抛海锚。
	stream	抛，射	(v.t.). To place overboard and secure, as to stream a LOG, or stream a sea anchor.	向船外投放并固定某物，如掷测程仪，抛海锚。
	stream: ebb	落潮流	See EBB STREAM.	落潮时水的水平运动。落潮流通常向海一侧，或者潮汐前进的相反方向。也称为ebb, ebb current 或 outgoing stream（落潮流）。
	stream: flood	涨潮流	See FLOOD STREAM.	涨潮时海水的水平运动。涨潮流一般流向海边或者沿着涨潮方向。亦称为flood，flood current或者ingoing stream（涨潮流）。
	stream: ingoing	进潮流，涨潮流	See FLOOD STREAM.	参见flood stream（涨潮流）。
	stream: outgoing	落潮流，退潮流	See EBB STREAM.	参见ebb stream（落潮流）。
	stream: rectilinear	直线流	See CURRENT: REVERSING.	参见reversing current（往复流）。
	stream: rotary	回转潮流	See CURRENT: ROTARY.	参见rotary current（回转潮流）。
	stream: tidal	潮流	See CURRENT: TIDAL.	海水在引潮力的作用下伴随落潮所产生的交替水平运动。亦称tidal stream。
	stream current	海洋急流	See CURRENT.	相对于较宽而弱的漂移水流而言，是一个狭窄的、深的并快速移动的水流。
	streamer	浮签，拖缆	A string of hydrophones towed behind a ship.	拖曳在船后面的水听器绳索。
	streamline	流线，流线（型）	A LINE OF FLOW. In METEOROLOGY, line envelope in space of the tangents to the instantaneous wind directions at a given time. Also written a... more A LINE OF FLOW. In METEOROLOGY, line envelope in space of the tangents to the instantaneous wind directions at a given time. Also written as two words. See also TRAJECTORY.	一种流动的线。气象学定义为：在确定的时间，空间中瞬时风向的切向包围线。有时也写为两个单词。
	streamline flow	线流	See LAMINAR FLOW.	流体沿流线平稳地流动，按层或片平行排列。相对于湍流。亦称streamline flow。
	strength of current	潮流强度（极限）	The PHASE of a TIDAL CURRENT at which the SPEED is a maximum; also the SPEED at this time.	速度最大的潮流相位；亦指这时的流速。
	strength of figure	图形强度	In GEODESY, the comparative PRECISION of computed lengths in a TRIANGULATION NET as determined by the size of the angles, the number of con... more In GEODESY, the comparative PRECISION of computed lengths in a TRIANGULATION NET as determined by the size of the angles, the number of conditions to be satisfied, and the distribution of BASES and points of fixed POSITION.	在大地测量中，三角测量网中被计算距离的比较精度，系通过角度的大小，要求满足的条件数，以及基线和固定点的分布来共同确定。这些关系即构成图形强度。
	striding level	跨水准器	See LEVEL.	水准器安放在测量或天文仪器上方且平行于水平轴，因此可保证用于测量水平轴到水平面的倾斜。通常安放在仪器的望远镜上。
	strip	带状流冰	In ice terminology, a long narrow area of PACK ICE, about 1 km or less in width, usually composed of small fragments detached from the main ... more In ice terminology, a long narrow area of PACK ICE, about 1 km or less in width, usually composed of small fragments detached from the main mass of ICE, and run together under the influence of WIND, SWELL or CURRENT.	海冰术语，意指宽度不超过1公里的长距离浮冰带，一般由从冰主体分离下来的碎块组成，这些碎块在风、浪涛或海流的作用下聚拢在一起。
	strip coordinates	航线坐标	See COORDINATES.	航线上任何点（无论是地面点还是实际空间点）的坐标。它们以首次重叠的空间坐标系统的原点和坐标轴为基准。
	strip film (or stripping film)	撕膜片	A film which has the emulsion coated on an extremely thin membrane which is in turn supported on a normal‑thickness film base. The emulsion ... more A film which has the emulsion coated on an extremely thin membrane which is in turn supported on a normal‑thickness film base. The emulsion and the membrane can be stripped (separated) from the base after exposure and processing. The thin image so obtained can be mounted face down on a new support for lateral image reversal or used for combining with, or inserting in, other image elements.	在标准厚度的片基上依次涂有极薄的表层和乳胶层的膜片。乳膜层和表层在曝光或处理后能从片基上剥离（分开）。由此得到的图形能固定在新的支持物表面，从而得到反像，或用于叠合及套入其它图形要素。
