半焦

By combination of balance equations of electron energy, current continuity equation and distribution function of electron energy, a model to simulate the coaxial RF discharge is set up.

结果表明：对于同轴环形波导，存在三种形式的低耦合损失谐振腔结构，即半共焦结构、半共心结构和平行平面腔结构。

The experimental research on Subpixel Technology is carried out too,using a distinguishability board as the object.

两帧图像可以采用焦平面阵列探测器获得〔3 ，4〕，也可采用线列探测器光机扫描获得〔5〕，它们在两维方向上各错开半个象元距离。

Making use of I1 ,I2 ,I3 position Centrifugal rate e and half focal chord p can be calculated. Therefore its easy to transform the equation of the right - angled coordinate branch into polar coordinate equation.

利用I1，I2，I3可以计算出离心率e和半正焦弦p因而可以很容易的直接把直角坐标系中的方程转化为极坐标方程。

The motion, creation and annihilation of phase singularities in the focal region take place, which depends on the truncation parameter, spherical aberration and half angle of the aperture lens.

在焦区位相奇点会出现移动、产生和湮灭，并与截断参数、球差和光阑透镜半角有关。

When you surround abundant in natural sights, you'd for surely meet lots of professional photographers and photographic enthusiasts with bulkiness lumpish photograph equipment, they're busy with changes camera lens, underpin bracket, lay out the digital accessories for better shots.

在这里特别值得一提的是NikonD300的半透式反光板结构有了一定的改变，为的是适应高速连续抬起和长时间连续抬起而设计，因为D300的LiveVIEW模式可以通过反差检测自动对焦，反光板自然也有对应的改进。

By controlling the size of pump beam and inserting an intracavity aperture in the plano-concave cavity, we obtain good contrast optical bottles at semi-confocal, 1/3-, and 1/5-degenerate cavity configurations, respectively.

只要适当的控制泵浦光斑与腔内实光栏的大小，在半共焦腔、1/3简并腔、与1/5简并腔下可以产生不同但是对比度极佳的瓶型光束。

The process can be wet, semi-dry or dry and the fuel can be pulverized coal, oil or gas.

这个过程可以是湿的、半乾的和乾的，燃料可以是燃煤、石油焦和燃油。

Diarrhea in children 5-10 times a day, the available coke rice soup, carrot soup, dilute奶糕, protein food such as 1-2 times in place of breast milk; also can switch to skim milk, semi-skimmed milk and yogurt, but also appropriate to add some sugar saline.

小儿每天腹泻5—10次时，可用焦米汤、胡萝卜汤、稀奶糕、蛋白质等食物代替1—2次母乳；也可改用脱脂奶、半脱脂奶以及酸牛奶，还要适当补充一些糖盐水。

While the camera is switched on it makes a quiet but distinct whirring sound all the time, and Ireally don't know why it should do this.

这不是自动对焦的马达，因为半按快门后也有，也不是变焦的声音，因为很明显是相机自己发出的。

The experiment was performed at the Asterix IV iodine laser with a prepulse 5 ns before the main pulse. Under optimum focusing conditions for main pulse and prepulse the X-ray laser beam splits into two beamlets along the target surface at its output end of the 2.5 cm long plasma column. The splitting was still observed when the prepulse alone was defocused.

实验发现在抽运激光主、预脉冲最佳聚焦条件下， X射线激光束在2.5 cm长的线状等离子体输出端沿靶面方向分裂成两束；在抽运预脉冲单独散焦条件下，仍然观察到这一分裂现象；但是当抽运主、预脉冲同时散焦时，这一分裂现象逐渐消失并获得了半宽度只有40 μm的非常窄的近场像。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
