自发的

The generating origin of the light field with SPDC expounded with the interaction of the pumping photons with the nonlinear crystals.

分析了单色泵浦光子流和量子真空噪声对非线性晶体的综合作用，从泵浦光与非线性晶体的相互作用过程解释了自发参量下转换光场的产生根源，推导了SPDC双光子态的数学表达式，并给出其几率解释

The creative works are as follows: 1. We show a scheme to generate high efficiency single photon via multi-dots delay detection with SPDC.

在这些研究工作中，属创新性工作的有两点： 1、提出了一种利用自发参量下转换过程采用多点延时探测触发获得高效单光子源的方法，可以利用它来实现基于单光子的量子密钥分配方案和量子计算中的量子逻辑门。

This character of the photonic crystal containing defect can be used to enhance spontaneous emission of atoms and to make narrow band filter.

光子晶体缺陷的这一性质具有很重要的实际用途，如增强原子的自发辐射、制作极窄带的选频滤波器等。

The effect of additives on the control of crystal size for sodium sulphate is discussed in the paper.

研究结果表明：十二烷基苯磺酸钠的加入增大了硫酸钠结晶过程的界面能，从而抑制自发成核过程的发生，促进晶体的生长，改善晶体的粒度。

Allenge.the rebellious tendency of emotion and nationally psychological custom appeared reasonable and no sensible form of superciliousness and jealousy and ill felling which was the road chinese intellectual who walked out from traditional form must follow or take.only after passing the blind and spontaneous stage,they possibly gradually changed and opened.

在传统面对挑战之际，他们很难心平气和地做出明智的选择，这种情感和民族心理习惯上的反抗趋势，呈现出合情却不合理的猜忌与恶感的样态，这是中国知识阶层走出传统模式的必由之路，只有经过这一盲目、自发阶段后，他们才能逐渐变化开放。

Empowered with the superincumbent rights, our local government has to maximize their own interest and at the same time fulfill their mission from the central government.

在自上而下的国家授权这一行政制度的保护下，我国基层政府将自身利益最大化目标与完成中央政府下达的任务捆在一起，自发地选择了追求增加自身利益、减少农民利益的种种行为方式。

Significant progress has been made by Dalibard,Dupont-Roc and Cohen-Tannoudji in 1982,who argued that there exists a symmetric operator ordering between the operators of atom and field that renders the distinct contributions of vacuum fluctuations and radiation reaction to the atom\'s spontaneous emission and energy shift separately Hermitian.

这种不确定性的根源来自于相互作用哈密顿量中原子和场算符的排序问题。1982年，法国物理学家Dalibard，Dupont-Roc和Cohen-Tannoudji提出原子和场算符对称排序的方法，从而消除了这种不确定性，使得真空涨落和辐射反作用对原子自发辐射和能级移动的贡献都是厄米的。

Because of these qualities that came sincerely and spontaneously from a generous heart, everyone flocked about her, for who can resist the charm of one who discovers in others admirable qualities undreamed of even by himself?

由于她具备这些诚恳而自发地出自一个宽广胸怀的美德，所有的人便都拥戴她，因为她既然能在别人的身上发现他们连自己也不曾梦想到的优良品质，谁还能抵挡住她诱人的魅力呢？

In reality, the formation of many brands, include the well-known brand, are all unprompted with its growth process; But along with competition turning worse, need to mold the brand with the engineering methods more and more now.

实际上许多的品牌包括著名品牌的形成和成长过程都是自发形成的，而随着竞争的加剧，现在越来越需要用工程化的方法来塑造品牌。
