查询词典 slit

A projection slit is illuminated by a collimated laser beam.The projection slit is projected onto an object to be measured with grazing incidence through a lens.After being reflected by the object,the projection slit is imaged on a detection double slit through another lens.

准直激光束照明的投影狭缝由一个透镜以掠入射角度投影在被测物体上，狭缝投影经过被测物体表面的反射和另一个透镜的成像在探测双缝上形成投影狭缝像。

Considering "addition theorem of probabilities", the above idea can be expressed as follows: Assum that a beam passes through a partition with two slit and arrives a screen. The probability of the event that an indivedual particle falls on somewhere of the screen under the condition that two slit open simultaneously, is equal to the sum of two probabilities of the same event under that two slit open in turn.

考虑到"概率的加法定理"，这种看法可表成："当一个拉子束通过一个带有两条缝的隔板到达一个屏上时，在两条缝同时打开的条件下单个粒子落在屏土某处的概率，等于在两条缝轮流打开的条件下该拉子落在该处的两个概率之和。"

Double slit diffraction is the double slit interference phenomenon modulated by single slit diffraction.

双缝衍射是指被单缝衍射调制的双缝干涉现象。

The present invention discloses one kind of double micro polarizing free stereo imaging device and method. The device includes image plane, slit grating and double micro polaroid. The double micro polaroid sandwiches the slit grating, and the micro polaroid in the image plane side is between the image plane and the slit grating. The double micro polaroid consists of two adjacent lines of micro polarizing units, which are orthogonally arranged.

本发明公开了一种双微偏振式自由立体成像的装置及其方法，该装置包括图像面、狭缝光栅以及双微偏振片，其中双微偏振片是指上下两层微偏振片将狭缝光栅夹在中间，其中处于图像面一侧的微偏振片处于图像面与狭缝光栅之间；所述的微偏振片由相邻两列微偏振单元的透光轴方向相互垂直的微偏振单元周期性分布构成，即所谓"正交排列"；所述的狭缝光栅由等宽度的遮光条纹平行排列组成。

The block of wood is 3/4" square and around 3 inches long. I made a slit in the wood with my hacksaw (the blade cut was the same as the brass) to about half way down the wood. I drilled a 1/4" hole perpandicular to the slit at the top of the wood and one just lower of the blade slit to house the shaft.

该座木材是3 / 4 "广场及约3英寸长，我作出了狭缝，在木材与我hacksaw，大约一半的方式下来的木材，我钻了一个1 / 4 "孔perpandicular向狭缝在顶端的木材和一只是较低的叶片狭缝向内务轴。

Because they are all derived from the behavior of single slit island under changing yardstick, which was inconsistent with the principle of slit island method that fractal dimension is calculated from the perimeter-area relation of many slit islands.

首次研究指出：文献中对码尺依赖性问题的已有解释以码尺改变时单个分形岛的行为变化为出发点，这与小岛法从大量断面小岛的周长-面积关系得到其周线分维数的测量思想不符合。

Moreover, the electromagnetic flux density and meniscus height increase in the form of chequerboard with increasing of slit number. The numerical results can exactly illuminate some experimental phenomena, and enrich the theoretical foundation of soft-contact continuous casting technology. In practice, a softcontact mold with slit number of 16 or 24 is recommended, the suggested frequency is around 20kHz, and the slit width is about 1mm.

结果表明：钢液对结晶器内的电磁场分布有很大影响；发现了磁感应强度和弯月面高度随电源频率增加而增大的频率范围、磁感应强度和弯月面高度随切缝数目增加呈&锯齿状&增大的规律；研究结果合理地解释了一些实验现象，完善了软接触结晶器电磁连铸技术的理论基础；建议在实际应用中采用分瓣数为16或24分瓣数的结晶器，电源频率应控制在20kHz左右，切缝宽度应控制在1mm左右。
