The very low natural IRSL and GLSL signal levels of about 80-100 photo counts per second, corresponding equivalent dose of less than 1Gy, were presented for most modern samples, and imply that the IRSL and GLSL signal zeroing could be reached during deposition for most of loess and water-laid sediments in North China.

华北地区大多数现代沉积物细颗粒组分的天然IRSL和GLSL信号水平很低，约80-100光子计数/秒，相对应的等效剂量值小于1Gy。这可能表明，华北地区大多数黄土及水沉积物的IRSL和GLSL计时器在沉积过程中可能已基本&回零&。细颗粒IRSL和GLSL的光晒退实验结果也说明这一点。

The region where it produces two-stream instability is encircles by three boundaries: the outer open field lines, the nearest distance where the instability could take place (corresponding the charactistical frequence is equal to the plasma frequence), and the largest distance where the instability could take place along field lines.

可以发生双流不稳的区域是由三个边界面围成的：一是最外的开场线。一是不稳定性可以发生的最近距离(对应于曲率光子特征频率等于等离子体频率的地方)，最后是沿磁力线能够激发起双流不稳性的最大距离。

Besides, the response time of this detector is only 230 micro seconds.

该微机械光子探测器的探测度D*估计达109cmHz1/2W-1，远高于其它非制冷红外探测器的灵敏度，而响应时间仅230微秒。

Objective: To observe the change of regional cerebral blood flow in different region of interest under quiet condition and performing hand motor condition with single photon emission tomography, elucidate the mechanism of the brain regions activated by simple hand motor (repetitive and sequential finger- to- thumb opposition movements in turn) and detect the role of active cortical areas by analyzing the difference of rCBF in different age groups.

目的：本研究的目的是运用单光子发射断层扫描仪对比观察正常人在安静状态下和执行手指简单运动状态下脑内不同感兴趣区（region of interest， ROI）的血流量变化情况，进而阐明简单运动模式下脑内运动相关功能区的激发情况，并通过分析不同年龄组运动区激发时血流量变化的差异来探讨运动功能区的作用，对于临床中枢神经系统瘫痪后的运动功能重建和康复训练具有指导意义。

It was set up the treat plans of three-dimensional conformal, the common three-field and four-field plan with the method of using 6MV photos.

In chapter 7 the photoassociation process inside an optical lattice is investigated. A scheme of controling the atom-molecule transformation process by sweeping the Raman laser frequency is proposed. With this scheme, the atom-molecule superposition state and coherent molecular output can be obtained.

在第七章，我们会考察光学晶格上的光子离解过程，并提出利用激光扫频的方法对光学晶格上的原子一分子相互转换过程进行控制，以得到稳定的原子一分子叠加态并实现分子相干输出的方案。

So many global shifts are underway at this time in preparation for the next entry into the fifth star gate towards the photon belt of the Great Central Sun.

在这个时刻很多全球变迁正在进行，为进入领向大中枢太阳光子带的第五个恒星门而准备。

At 3000 strands, one will capture much more dream and have much more possibility therefore opened unto oneself in terms of what one may wish to experience for the remainder of this life. 3000 strands also rolls back the clock and de-ages the form enough that one may live well into the entry of the final star gate or photon belt and beyond.

在3000股 DNA ，你将捕获更多梦想，并因此能打开你所希望在剩余生命中所体验的更多可能。3000股也能拨转时钟，将形体足够返老还童，让你能很好生活到最后一个恒星门的进入或光子带及更远。

The dispersion properties of photonic crystal fiber was analyzed by an effective refractive model in detail, and the eigenvalue equation of the fundamental space-filling mode in infinite air silica micro-structure was presented.

采用有效折射率模型详细分析了光子晶体光纤的色散特性，并给出了无限大空气玻璃微结构中基模的本征方程。
