查询词典 rectangular axes

With the three axes circumrotation method, the position of the incident laser is unchanged, and the conversion from the complicate three-dimensional spatial position relation into a two-dimensional plane is realized, by adjusting the relative positions of the detector and the target with certain spatial conversion relation.

采用三轴旋转方式，保持入射光源的位置不变，调整探测器和待测目标的相对位置，配合一定的空间转换关系，实现了将复杂的三维空间位置关系转换到二维平面进行调节。

In order to extract cophasal axes more continuous and immune to noise, a novel approach is developed based on edge detection.

实验结果表明应用该方法可以提取连续、准确的同相轴。

Cophasal axes on seismic sections play an important role in geologic stratification, fault interpretation, detection of cavities and other anomalous bodies in geophysical prospecting.

地球物理勘探中，地震剖面中的同相轴对地质分层、断层解释、有无形成空洞以及其它异常体的检测中作用重要。

The ordinary edge detection methods such as Sobel and Canny operators are immune to noise, which result in cophasal axes discontinuity due to lack of edge information caused by noise.

由于边缘检测中常用的Sobel算子和Canny算子检测同相轴时对噪声免疫差，常因噪声因素引起边缘信息缺失导致同相轴提取不连续，本文采用中值滤波并对Sobel算子进行改进，对地震剖面图进行预处理，结合均方差自动确定阈值并进行异常检测，提取完整同相轴。

The reliability of analysis result depends largely on the in-house experimental conditions. Unlike the previous analysis that only concerns the sole effect of permeable pressure, this article considers both permeable and confining pressure and deformation characteristics of concrete material under the interaction of them according to the real work state of construction, which may leads to the changing pattern of permeable rate as listed below: permeable rate always reaches its peak with the time process going on, than goes down and remains straight on some certain value; The PR will tend to decline while the confining pressure is increased, and the time taken before the peak will be extended as well; Under the constant permeable pressure and circularly changing confining pressure, the minus-exponential ascend and descend relationship could be applied between the PR and Time axes respectively with crannied and intact concrete samples, and the PR of crannied concrete is far more larger than that of intact concrete. The change pattern of concrete could also be mathematically analogized using the least square method.

室内的实验条件是研究成果可靠性的重要因素，而以往的研究都只考虑了渗透压单一作用，本文根据混凝土结构的实际工作状态，同时考虑了围压与渗透压共同作用下的混凝土材料的渗透性变化特征，得出了混凝土材料在围压作用与渗透压共同作用下的渗透率的变化规律：渗透率都是随时间推移先达到一个峰值，再降低并趋于平稳；渗透率会随围压的增大而减小，并且峰值的到达时间也会随之延长；在渗透压不变，围压升降循环的情况下，有裂缝、无裂缝混凝土的渗透率变化规律是随时间成负指数关系上升、下降，且有裂缝混凝土试件的渗透率远远高于无裂缝混凝土的渗透率，并对混凝土的变化规律运用最小二乘法进行数学拟合。

It has 12 rhomb-shaped faces, each of which intersects two of the crystallographic axes and is parallel to the third.

有12菱形面孔，分别由两个相交的轴线，并平行于晶三。

It has 12 rhomb-shaped faces, each of which intersects two of the crystallographic axes and is parallel to the third.

它拥有12个菱型脸，分别由两个相交的轴线，并平行于晶三。

Software, and simulated by Monte Carlo method. The simulation results are conducted by descriptive statistics. Two "drop-in" assembly design lens groups were studied to calculate the stack-up element tilt and decenter within a cell and the resultant deviations of the optical axes away from the mechanical datum axis. The results indicate that the opto-mechanical tolerance model can analyze the critical to quality parameters of a lens system. As a result, the performance of the lens system can be anticipated by the opto-mechanical tolerance model before mass production.

戊n体编辑，并以蒙地卡罗方法模拟，模拟结果以叙述统计呈现；最后以两个&投入式&组立设计的镜群组为案例，计算镜片在镜筒内的累积偏心角度公差、偏心距离公差及镜片光学轴的累计偏移量，其结果显示该模型可模拟一个镜头系统的关键品质参数；所以，镜头系统的性能在大量生产之前可藉本光机公差模拟模型预测其品质与良率。

They performed consciously era's awful command, constructed their literary thought on the axes of political discourse: overstating literary societal political function, emphasizing literary class nature and party spirit, affirming to take over literary domanial discourse hegemony, carrying actively out "socialism realism", so that disregarding liter...

他们都自觉地执行时代的威严命令，建构了以政治为轴心话语的文艺思想：夸大文艺的社会政治作用，强调文艺的阶级性和党性，主张争夺文艺领域的话语霸权，积极推行&社会主义现实主义&，从而忽视了文艺自身的规律和独立性。
