In this paper, we have studied the dimensional effects, electronic state, the configurations of charge density and spin density for quasi-one-dimensional organic ferromagnets. First, considering interchain interaction, the itineracy of electrons, the electron-electron correlation, electron-phonon interaction and spin correlation in low dimensional system, we proposed an interchain coupling theoretical model for conjugated system and non-conjugated system of organic polymer ferromagnets, respectively. Based on the theoretical model, we studied the electronic property, spin structure, the configuration of dimerization and the stability of the ferromagnetic state with a self-consistent iterative method.

From the calculations, it can draw the conclusions:① The interaction potentials induced by the interaction of phonons with the ele ctron can be divided into two parts. One is only relevant to the coordinate z 1(z2), and the other is relevant not only to z1 and z2 but als o to ρ.② The absolute values of the induced potentials VIL and VI,σ decrease with the increase of ρ.③ The abs ol ute value of IO-phonon-induced potential decreases with the increase of the qu antum well width.

通过计算可得出如下结论：(1)双极化子的诱生势可以分为两部分，其中一部分仅与一个电子的坐标z1(z 2)有关，另一部分则不仅与两个电子的坐标z1和z2都有关，还与两个电子间的相对距离ρ有关；(2)诱生势VIL和VI，σ的绝对值随着双极化子中两个电子间相对距离ρ的增加而减小；(3)由于电子与IO声子相互作用而产生的诱生势VI，σ的绝对值随量子阱宽度N的增加而减小。

Week anchor: Above all above the circumstance conference that boat has been in the country for many times, very much person tells electronic business affairs is Alibaba the thing of the respect, the likelihood is a few views of layman, if say it pays treasure subordinately for example, these are pure business, if be of itself, if be electronic business affairs a bit far-fetched, if say the business affairs that is BTOB, use Internet and the method of other a few electrons, use a company with the business affairs activity between the enterprise, alibaba is electronic business affairs, you also can say sina is electronic business affairs, right incorrect?

周锚：首先国航已经在多次的场合会议上面，有很多的人一讲电子商务就是阿里巴巴方面的事情，可能是门外汉的一些看法，如果说它旗下的比如说支付宝，这些是纯商业的，如果是本身的，如果是电子商务有点牵强，如果说是BTOB的商务，利用互联网和其他的一些电子的手段，利用企业间与企业间的商务活动，阿里巴巴就算是电子商务，您也可以说新浪是电子商务，对不对？

Based on the experimental data of low (less than 13) ionization energy of lighter elements, the function of shielding coefficient, electronic states and atomic number is summarized when the atom ionizes electron in different electronic state of the second and first shell.

The conclusion is drawn from the simulations that the secondary electrons will go out from the sample surface more easily with the decrease of the half cone angle of tip and the increase of secondary electron energy, tip-sample separation and the distance of the emission site away from the point directly under the tip.

模拟的结果发现针尖半锥角越小、次级电子能量越高、针尖样品间距越大、次级电子出射位置离针尖正下方越远则越有利于次级电子的逸出，此外通过栅网与一个平行于样品表面的地电极的共同作用，会对次级电子产生聚焦作用。

At ψ=30°. 2. To obtain 〓 from the background of a direct Auger spectrum N Because the total Auger electron yields are only about 10〓 of the backscattered electron yields in the N spectra, the backgrounds of the N spectra are mainly formed by the backscattered electrons.

由于N谱中俄歇电子的产额只占背散射电子产额的10〓左右，因此背景主要由来自样品的背散射电子构成，其中包含着与背散射电子能量分布有关的信息。

MPI may result in a sharp rise of threshold fluence Fth on \tau, and AI may lead to a mild increase or even a constant value of Fth on \tau. MPI serves the production of seed electrons for AI when the electron density for AI is approached or exceeded before the end of MPI.

MPI结束之前所离化的电子密度如果达到或者超过AI电子密度，则意味着MPI是产生种子电子的主要渠道，此时初始电子密度的影响可以忽略。
