The diffraction theory of Kirchhoff is applied to the four-pinhole aperture diffraction screens, the intensity, the zero-contour of the real and imaginary parts of complex amplitude and the phase distribution in deep Fresnel diffraction region are simulated, and it is found that the bright spots in interference field show central symmetry distribution. When the observation plane close to the diffraction screen, the zero-value points of light intensity can form line segment, on which the eccentricities of the light intensity isoline are close or equal to 1, the intensity changes very fast on both sides of the zero-line of light intensity.

We expect it will benefit the industry field to break through the optical measuring limits at present by offering some new ideas. Optical measuring research based on moire interferometry has developed for several decades. The main idea of this research is to utilize the moire effect caused by two superimposed gratings of identical or similar spatial frequency. One is the reference grating and it is a virtual grating created by a computer program in this research; The other grating is the image of grating projected on the measured surface by the DLP projector, and this grating will distort because of the different sloped profile of the surface. To superimpose the program-created grating and the captured distorted grating will derive the so-called moire effect. This research combined the basic theory of optical interferometry and moire effect to project the different phases of the projected grating fringes by the phase-shifting method and compute the principal value of arguments between -π,π. In the end, the phase unwrapping program based on discrete Fourier transform of solving PDEs is used to unwrap the phase of the measured surface, and finally the surface profile is derived by the optical measuring system.
以叠纹干涉术为基础的光学检测研究之发展早已行之有年,而在本研究中所采用的投影叠纹法(Projection moiré)之主要精神在於藉由两道空间频率相近或相同的光栅相互叠加而成的效应,其中一道为参考光栅,而本研究中的参考光栅是以程式产生可调整不同空间频率的虚拟光栅;另一道则为投影至待测物表面的光栅影像,而在起伏高度不一的待测表面上的光栅影像会受到待测物表面起伏状况不同而在观测方向产生光栅投影条纹影像的歪曲变形,将电脑产生的参考光栅与由影像撷取装置所获取投影於待测物表面的光栅影像作叠合,便会产生所谓的叠纹效应;利用基本的光学干涉理论与叠纹效应结合,本研究中以相移法来改变投影於待测表面的光栅相位,再以相移法的理论反运算出在带有待测面各点高度资讯之介於-π,π相位主幅角,再以离散傅立叶转换解偏微分方程的相位重建程式还原待测面的相位值,以得知待测面之表面轮廓。

Randomly adopted 1000 students from 6 country middle schools and 4 country elementary schools, and get 813 available subjects. We can find that: the percentage of Left-behind children is the largest in the whole children, especially Left-behind children who have only one parent; and mentally healthy situations of Left-behind children are poorer than those who are not, the poorest are children who are looked after by compeers or even no rearings; the situations of children who have been Left-behind children also are not so good, there are significant differences mentally healthy between them and those who have not been, while anxiety scores are only a little lower. And there are differences in sex, grade, quarter, single or not and years parents being out among those who are Left-behind children. There are differences of parenting styles among different styles of children caring. Totally speaking, the scores on positive parenting styles of no left-behind children(such as warmth of father and mother) are higher than those who are and who have been left-behind children, but the scores are obviously lower on negative parenting styles such as punishment from father or intervening punishment from mother. The regression equation of anxiety scores on left-behind children set by parenting styles also depends on children caring styles. Positive parenting behaviors of parents and caring people have positive influences on mentally healthy of children, for instance, some supporting and mood warmth., while some negative behaviors such as rejection have negative influences.
随机抽取了江西省的6所农村中学和4所农村小学,调查学生被试共计1000人,有效被试为813人,对调查数据进行分析后发现:留守儿童所占的比重在全体儿童中最大,尤其是单亲看护人的留守儿童;而且,留守儿童的心理健康状况也显著低于非留守儿童,情况最差的是同辈看护或无看护的留守儿童;曾留守儿童的心理状况也不尽如人意,它与非留守儿童的心理健康差异达到了显著水平,心理焦虑总分只是稍低于留守儿童总体;并且,留守儿童的心理健康同样存在着性别、年级、独生与否、住宿与否以及父母打工年数的差异;不同看护类型的留守儿童父母教养方式存在着差异,总的来说,非留守儿童积极性的教养方式(如父亲温暖、母亲温暖等)得分要高于留守儿童和曾留守的儿童,而在很多消极性的教养方式如父亲惩罚、干涉,母亲干涉惩罚等等上,留守儿童与曾留守儿童的得分又要显著高于非留守儿童;家庭教养方式对留守儿童焦虑总分的回归方程视儿童的看护类型而定,父母和看护人的一些积极性的抚养行为对儿童的心理健康有着积极的影响,比如情感温暖或者支持温暖等,但是一些消极的比如拒绝等对留守儿童的心理健康就有负面的影响。

Our investigation has shown that:ⅰ there was an interference effect between the incident and reflected matter waves as all the atoms in BECs were coherent;ⅱ considering the rotation of a vortex, the nonuniform velocity distribution along the surface would play an important role in the quantum reflection process. For example, they would change the characteristics of the interference fringes between the incident and reflected matter waves;ⅲ the reflected vortex became unstable for sufficiently low incident velocity or strong interaction. This sort of instability physically originated from dynamics excitations induced by the atomic interaction in the quantum reflection process.
我们的研究表明:ⅰ由于相干性质的存在,在涡旋与固体表面相互作用的过程中,被固体表面反射回去的部分与正在入射的部分在空间叠加后一定会产生清晰的干涉条纹;ⅱ由于各向异性的速度分布,涡旋的反射率也呈各向异性,因此反射回来的部分与入射部分形成的干涉条纹宽度以及疏密程度与入射速度以及速度各向异性的程度有关;ⅲ由于玻色凝聚体中原子间相互作用的存在,反射过程中凝聚体会产生激发,破坏涡旋的结构,使得反射后的涡旋不再是中心对称。
