高磁场

It remains disputable that birds can obtain geomagnetic information for homing because otoliths in the lagena are rich in elements Fe and Zn.

有人认为瓶状囊的耳石中Fe、Zn等元素含量较高，使得鸟类能够感受地球磁场而具有导航能力，但这个假说目前还存在争议。

The macula lagena is innervated and has neural projections to the brainstem, but its physiological function is still unclear. It remains disputable that it is because otoliths in the lagena are rich in elements Fe and Zn that birds can obtain geomagnetic information for homing.

Results are summarized as follows:(1) The absorption property of CdSe nanoparticle colloid under magnetic field was investigated by magnetic circular dichroism measurement, which proved the discrete energy states in CdSe nanoparticles due to size confinement effects.(2) Aggregation of small nanoparticles was usually observed under HRTEM measurements. In order to obtain HRTEM images of well dispersed particles, surfactant molecules were assembled on the surfaces of mercapto acetate stabilized CdSe nanoparticles.

主要内容如下：（1）用磁圆二色吸收谱测试研究了CdSe纳米颗粒的水溶胶在磁场中的吸收性质，验证了CdSe纳米颗粒中由于量子限制效应而存在的分立的能态；（2）用高分辨透射电镜观察到纳米颗粒的团聚，在颗粒表面接枝上含长链烷烃的表面活性剂分子，使颗粒有效的分散，解决了纳米颗粒团聚的问题。

Diode pumped monolithic nonplanar ring laser has the advantages of compactness, reliability and high efficiency.

激光二极管抽运的单块非平面环形腔固体激光器具有结构稳固、效率高等优点，在一定的纵向磁场作用下，可形成单向行波振荡，纵向抽运时就可得到较高功率的单频输出，有广泛的应用前景。

Resultant energetic particles such as electrons and protons rain down near the Earth's poles and impact the air. The impacted air molecules temporarily lose electrons, and when oxygen molecules among them reacquire these electrons, they emit green light.

极光是由来自太阳的高能粒子冲撞地球的磁场所触发的；其结果是高能量的电子和质子在地球的极区附近撞击大气，让被撞击的空气分子短暂失去电子，如果是氧分子重新得回这些电子，就会发出绿光。

The amorphous magnetic field senso r of pulse induction type has high sensitity and good stability as we ll as low requirement of work cond itons.

脉冲感应型非晶态磁场传感器具有灵敏度高、稳定性好、对使用环境要求低等特点。

RPMF can regulated the course of femoral head necrosis in various critical-aspects, will be a promising measure of the prevention an treatment of steroid-induced necrosis of femoral head, especially on the early stage; micro-CT features diagnostic superiority of substantivity and sensitivity.

磁场可以针对股骨头坏死主要环节高脂血症、血液黏稠度增加、关节腔压力增高等发挥调节作用，有效治疗激素性股骨头坏死，尤其是早期病变；显微CT在诊断激素性股骨头坏死方面具有灵敏性和直观的优越性。

The contents of metal elements Zn, Ba and Cu in lagenal otoliths were lower than those in saccular otoliths. Conclusion The contents of magnetic elements in lagenal otoliths of homing pigeons are not much higher than those in utricular and saccular otoliths, which does not support the hypothesis that birds depend on high contents of Fe and Zn in lagenal otoliths for sensation of geomagnetic information.

结果表明成年信鸽瓶状囊耳石中磁性元素的含量极低而且不比内耳球囊和椭圆囊耳石更丰富，从而不支持信鸽因其瓶状囊耳石中含有较高的Fe、Zn等元素而能够感受地球磁场这一假说。

The granular-type film has a smaller demagnetizing field than the continuous film, thus it shows larger switching field and has great potential in high density perpendicular magnetic recording technology.
