It is found that:(1) the variation of dFM may lead to two different features for the IEC,one is the oscillatory behavior of IEC with the spacer thickness,the other is the exponential behavior in the most spacer thickness.(2)As a oscillatory function of dFM ,the IEC exhibits multiple periods and a negative non-oscillatory term.(3)The Fermi energy of the conduction electrons has a little variation as the magnetization of the two FMs changes from parallel to antiparallel alignment,furthermore,this variation is correlated with the IEC to some extent.

结果发现：（1）dFM的变化会导致层间交换耦合出现两种不同的特征，一种是随着中间层厚度的增加，IEC有振荡行为；另一种是其指数衰减行为；（2）作为dFM的振荡函数，IEC表现出多个周期和一个负的非振荡项；（3）传导电子的费密能会随着两铁磁体的磁化排列变化而稍有变化，进一步地，这种变化与IEC有着某种程度的关联。

In this exper iment,we took the advantage of RNAi technique,microinjected tinman and singless dsRNA into the early embryos in Drosophila respectively and got these two genes' RNAi phenotypes,which were very similar to that of their mutant,showing heart tube defects or no heart precursors formation.tinman dsRNA eve caused visceral mesoderm defects and the somatic muscles disruption,yet wingless dsRNA only affected heart precursors and had no effect on visceral mesoderm and somatic muscles,indicationg that the heart-related genes dsRNA interference worked effectively and exclusively in Drosophila.

实验运用RNAi技术，分别将tinman和wingless的dsRNA注入果蝇的早期胚胎，得到了这两个基因的dsRNA干扰表型，与两个基因的突变体表型非常相似，都表现为果蝇心脏前体细胞不能形成或心脏管缺失。尤其是tinman基因的dsRNA，还引起了肠中胚层缺失和体壁肌肉组织的紊乱，而wingless基因的dsRNA却只影响心脏的形成，而不影响肠中胚层，说明dsRNA干扰具有非常强的特异性，因而不失为研究果蝇心脏发育基因功能的有效方法。

This can result in a splitting ofwavelength-dependent loss band and make the codirectional mode coupling condition (of the fundamental core mode into cladding modes) be different at two principal input polarizations.In a PM-LPG fabricated with a PMF having relatively small birefringence , the adjacent resonant dips (slow-axis and fast-axis resonant dips) resulting from the two principal input polarizations have identical cladding mode order and the wavelength separation between them is several nanometers

这可能导致分裂的ofwavelength-dependent损失，使codirectional乐队的耦合条件(模式基本核心人才培养模式为层模式)是不同的两种主要的输入波在PM-LPG捏造和具体情况有相对较小的双折射，相邻的谐振(slow-axis和fast-axis引起共振蘸)的两种主要模式有相同的输入波的波长层顺序和他们之间的分离是几奈米的图案

Both crystallographically unique Zn atoms exit as an octahedral geometry. The four equatorial positions of Zn1 atom are occupied by the carboxylate-oxygen atoms of the two tartrates, and the two oxygens of the left four carboxylate-oxygen atoms coordinate to two different Zn2 atoms, respectively, forming infinite coordination polymer chains. The left two of the trans equatorial positions of Zn2 atom are completed with two oxygen atoms of two water molecules. The axial positions of both Zn atoms are occupied by the nitrogen atoms from different 4,4'-bipyridine molecules to give a 2D rectangular-grid layers with a cavity dimension of 0.51165(3)nm×1.13896(5) nm. A three dimensional network is formed by the crystallization water chains joined by the carboxylate-oxygen atoms through hydrogen-bonding interactions.

两个晶体学独立的Zn原子均为八面体构型，其中Zn1原子赤道配位点被2个酒石酸根中的4个羧酸根氧螯合配位， 2个酒石酸根中剩下的4个羧酸根氧中的2个分别与2个Zn2原子连接形成无限一维链， Zn2原子的另外2个反式赤道配位点被2个水分子氧占据，同时这两种Zn原子的轴向配位点均被4，4'-联吡啶的氮原子占据，形成具有矩形格子[0.51165(3) nm×1.13896(5) nm]的二维层状结构，游离的2个水分子通过氢键作用形成二聚体，并与酒石酸根中未与Zn配位的羧酸氧连接，把二维层状结构连接成三维网状的超分子结构。

The shortage of this way was that feeder cells could be passaged together with hESCConclusion HAFi could replace MEF as feeder layer to support the long-term culture oftwo Chinese human embryonic stem cell lines. This could remove the cells of animal originand heterogenetic pollution in the culture system. It also reduced the culture of primarycells and solved the instability caused by different batches of primary cells.

结论HAFi细胞可以用做两株中国人胚胎干细胞培养的饲养层，取代MEF后解决了动物源性细胞混杂和异源污染问题，省却了饲养层原代细胞的培养步骤同时解决了由不同批次饲养层差异带来的培养体系的不稳定。

Wire resistive touch screen technology, the grass-roots to the voltage field in both directions through the precision resistor networks are added to the work of conductive glass surface, we can simply be understood as the voltage field in both directions of staggered working hours added to the same work surface, The outer layer of Ni-Au conductive layer is only just used as a pure conductor, there are time-test, after touching the inner ITO contact point X-axis and Y-axis voltage value method measured touch point position.

五线电阻技术触摸屏的基层把两个方向的电压场通过精密电阻网络都加在玻璃的导电工作面上，我们可以简单的理解为两个方向的电压场分时工作加在同一工作面上，而外层镍金导电层只仅仅用来当作纯导体，有触摸后分时检测内层ITO接触点X轴和Y轴电压值的方法测得触摸点的位置。
