x-rotation
解釋
繞x軸旋轉-
Several cd1 - xznxte ( with the original concentration of x = 0. 04 ) crystals of different sizes were grown by bridgman methods modified with the accelerated crucible rotation technique ( acrt - b )
本實驗採用加入加速柑禍旋轉技術的bridgman法，生長了兩種不同尺寸的cdl _ xznxte （起始組分為x = 0 . 04 ）晶錠。 -
Finally, due to the rapid rotation of the neutron star, or the evolution of the companion, the infall of matter stops, the x - ray emission declines, and the neutron star emerges as a radio - emitting millisecond pulsar
最後，由於中子星疾速的自轉，或是伴星自身的演化，物質的流入停止， x射線輻射減弱，這顆中子星就呈現出了毫秒脈沖星的面目。 -
In the terms of interpolation, the image reconstructed from nearest interpolation or linear interpolation has good edge but serious noise ; reconstruction from 4 * 4cubic interpolation or three b - spline or three - order lagrange interpolations has better local character. 2 x 2cubic interpolations which has both better edge and local character is the ideal interpolation, the following is the basic principle during reconstruction : ( 1 ) the more width of interpolation, the more number of summation and the more order of interpolation polynomial, the higher of density resolution ; ( 2 ) the more of interpolation polynomial and width of interpolation, the more of reconstruction time simultaneously, aimed at eliminating the effects of noise contained in projection data, in this paper, author analysis cause and effects of common artifacts. importantly, discusses convolution back - projection reconstruction algorithm with a shift axis of rotation has been derived for correcting images that acquired with a divergence axis of rotation using the fan beam geometry with an angle - equaled detector
在ct圖像重建時，選擇有限帶寬窗有較好的空間解析度，三角形窗有較好的密度解析度，選擇餘弦窗則使得空間解析度與密度解析度的折衷；從窗函數的頻譜角度來講，可以用於圖像重建的一個良好的卷積窗函數應該具備以下條件： （ ? ）小的3db帶寬b ，即最小的主瓣寬度； （ ? ）最小的旁瓣最大峰值a ； （ ? ）最大的旁瓣峰值衰減速度d ；就內插函數而言，臨近點內插與線性內插重建圖像噪聲大，但有較好的邊緣與細節； 4 4三次內插、三次b -樣條與四次拉格朗日多項式內插圖像平滑，局部特性較好。 -
( 5 ) aiming at the sls technology, the relationship between the rotation angle of mirror and x, y coordinates of scanning point are derived theoretically, according to which the cli file can be translated into pmac instructors
（ 5 ）針對sls工藝，從理論上推導了振鏡式掃描系統中振鏡轉角與x 、 y坐標之間的關系，為cli格式文件向pmac運動程序的數據轉化提供了理論依據。 -
For information about how to calculate quaternion values from a direction vector x, y, z and an angle of rotation, see
有關如何計算從方向向量（ x ， y ， z ）和旋轉的角度計算四元數值的信息，請參見 -
Relative to the object s local coordinate axis, this is equivalent to rotation around the z - axis, followed by rotation around the x - axis, followed by rotation around the y - axis
相對于對象的局部坐標軸，此轉換等效于首先圍繞z軸旋轉，然後圍繞x軸旋轉，最後圍繞y軸旋轉。 -
