旁轴

A Study on Fraunhofer Double-Slit Diffraction by Applying Simulation Technology;2. Based on Kirchhoffs theory,the approximate intensity formulas of double-slit diffraction of Gaussian Beam is derived under paraxial approximation with power series expansion methods.

依据基尔霍夫衍射理论，利用幂级数展开的方法推导出旁轴条件下高斯光束双缝衍射的近似光强计算公式，并通过数值计算对双缝衍射的基本特性进行了讨论，得出了与其他文献一致的结论，得出了高斯光束下的双缝衍射极小值点比平行光束双缝衍射的极小值点向外移，观察屏中心光能变小；光强分布可由激光斑在衍射屏处的参数调制的结论。

A modified Vlasov equation which describes the evolution of the spatial and momentum distribution of axisymmetrical electron beams is developed based on the statistical dynamics theory.

利用统计动力学方法建立了描述旋转对称电子束的电子空间及动量分布演化的变态伏拉索夫方程，并在一阶旁轴近似下研究出一种半解析计算方法。

The invention relates to a paraxonic powder-feeding device based on the laser powder filling weld and relative power-feeding method, belonging to the laser material manufacture technique.

本发明涉及一种基于激光粉末填充焊接的旁轴送粉装置及送粉方法，属于激光材料加工技术领域。

The inventive powder-feeding device and method can effectively and easily process the paraxonic powder-feeding laser powder filling weld on the round and arc track of machined surface.

本发明的送粉装置和方法，可以有效、方便地对加工平面上为圆形、圆弧形轨迹进行旁轴送粉方式激光粉末填充焊接。

Even the scalloped rings of Nikon's first SLR lenses were far better, as were the wider rings on Nikon's 1940's rangefinder lenses.

即使是尼康的第一单镜反光相机镜头扇形环远越好，因为人的尼康1940年的旁轴镜头更广泛的戒指。

It's got a bulb mode, which keeps the shutter open as long as you hold the trigger down, and a lomo flash: twist the end of the flash to select different color gel filters, creating some cool effects .

它有一个泡泡模式，当你按下快门的时候，它会将镜盖打开，。扭动旁轴，选择不同的颜色滚动条，制造超炫的效果。

Before the M8 review I had no experience of rangefinder photography, something I considered relegated to history.

之前为M8做评测，我并没有旁轴的摄影经验，是我认为它已成为历史。

I will devote the first part of this review to considering the Contax G2 AF rangefinder system on its own merits.

我将首先实事求是是回顾一下Contax G2自动旁轴照相机系统的特点。

It can take very good photographs. It is easy to use. It is flexible for a rangefinder. It is noisy. This is the worst thing about G2 in my opinion.

我想说的是：它能拍摄非常棒的作品；它非常容易使用；它相对于一个旁轴相机来讲适用范围广；它非常吵，这是我觉得G2最不认人满意的地方。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
