单极

ResultsAfter seven days of culture, some BMSCs appeared typical morphological neuronal traits: the refractile and conelike or spherical cell bodies and long processes, expressed Nestin or NSE or GFAP.

结果 实验组诱导7 d后有部分细胞具备神经元样细胞形态，胞体锥形或圆形，有较长单极或多极的突起，均有Nestin、NSE、GFAP阳性细胞表达，且3种细胞数量差别有显著性（t=3.266~6.099，P.05）。

Delay distortion caused by log-periodic antenna can be avoided by changing its feed ing method; Reflection can be greatly reduced by resistively loading antennas as cylindrical monopole antenna,conical monopole and TEM horn antenna, resulting in better characteristics in radiating pulse signal.

改变对数周期天线的馈电方式可以避免滞后失真；根据 WU- KING偶极子理论，对圆柱单极子天线、单圆锥天线和 TEM喇叭天线等进行加载可以有效减小反射，改善了天线辐射短脉冲的性能，但同时也导致了辐射效率的降

Moreover, the spatial bifurcation of Mermin-Ho vortices and the generation and annihilation of monopoles are also discussed.

同时，文中还论述了Mermin-Ho涡旋线的空间分岔理论和单极的产生和湮灭理论。

For the time being, however, the demographic divide persists, and it does much to explain the polarisation of opinion over gaming and, in particular, worries about violence.

但是在目前，人口统计学方面的分歧仍然存在，这也造成了对于游戏的单极态度，尤其是对于游戏的暴力影响的担忧。

The effective channel mobility of4H-SiC MOSFETs is increased significantly by high temperature anneals in nitric oxide.4H-SiC MOSFET with hydrogen postoxidation annealing has a lower threshold voltage of3.1V and a wide gate voltage operation range in which the inversion channel mobility is more than100cm 2 /Vs.

SiC的雪崩击穿电场是Si的十倍，因此，理论上SiC单极功率器件的导通电阻可以比Si器件的低400倍，但在6H-SiCMOS结构中，由于反型层的电子迁移率较小，沟道迁移率测量值仅为40～50cm2/Vs，远远低于6H-SiC的体迁移率400cm2/Vs眼1熏2演，限制了SiC功率MOSFET的导通电阻Ron。

And the more his critics carped, the more those critics played into the role he'd written for them— a band of out-of-touch, tax-and-spend, blame-America-first, politically correct elites.

他的批评者也泼冷水，他们自己却越在里根为他们规定好的角色中买力——未知的同盟，税收和消费，批判美国单极独大和政治精英。

A novel kind of rectangle column monopole antenna is presented.The equivalent diameter of the antenna is thick due to the double rectangular radiation plates connected with the metalized holes.

一种PCB柱形接地单极振子天线，通过利用PCB双面板的特性，制作出一个双面柱形振子天线，增加了天线的等效直径，展宽了天线的阻抗带宽。

Material and Methods:unipolar hip replacement in 2 patients,bipolar hip replacement in 10 patients,total hip replacement in 6 patients,mean years of follow-up is 2years and 4months,applying with Harris score system to examine patients,while photoing hip X-ray on anteroposterior and lateral sites,.

材料与方法：对18例髋关节置换术后患者进行随访，其中髋关节置换单极2例，双极10例，全髋6例，其平均随访时间为2年4个月，应用公认的Harris髋部评分系统，在疼痛、功能、活动范围和畸形四个方面进行临床检查，同时行髋部正侧位拍片检查。

Under the situation of new class reform fable teaching in the mid-low grade of elementary school exposes all sorts of lagging teaching way and teaching idea which like that overtaking academic learning and lacking of appeal; the teaching main body lists polarization, the teaching ways are unitary; neglecting the student's individual difference and unhooking connections between study obtained and the individual experience.

新课改教育大背景下的小学中低年级寓言教学，暴露了种种滞后的教学方式、教学观念。如寓言教学重视究理而忽视了文趣；教学单极主体化、教学方式单一；忽视学生个体差异，学习所得与个体经验的脱钩等。

The two-ring monopole antenna can improve the wind resistance capability while maintaining the basic characteristics of the antenna.

此外，由于此超宽带双环单极天线的环宽很窄，可以用软金属做成可折叠的便携式天线，具有较高的实用价值。
