According to the different orientations of domain walls with respect to the (100) observation plane of a foil, 90°domain boundaries may be divided into two kinds. one is thin lens or ring shaped a-a 90°domain boundary, and the domain wall lies on the {110} plane; Usually, most of these domain boundaries are uncharged; according to the extinction rules for the (011) domain walls, the displacement vector 〓 along 〓 can be dertermined, which is parallel to the line of intersection between the domain wall and the plane consisting of spontaneous polarization vectors on both sides of domain boundary; from selected area electon diffraction of crystals including domain boundary, we not only examine slight difference in the crystal parts on both sides of the domain boundary, but also obtain crystallographic relationship between them, that is, there exists a 180°rotation symmetry operator along a normal of domain wall. The other is Z or ring shaped a-c 90°domain boundary along {010} direction, and the displacement vector 〓 runs along 〓 direction.

根据界面相对于样品中(100)观测面取向的不同，90°畴可分为两类：一类为薄透镜片状或环状的a-a90°畴，其界面平行于{110}，多数不带电，由消光规律可确定其位移矢量平行于畴界面与自发极化所在平面的交迹，即，〓方向，而从包含畴界的选区电子衍射图可知，这种不带电的90°畴界两侧存在微小的取向差，其界面两侧的结晶学关系为以界面法线为二次轴的旋转关系；另一类为Z状或环状的a-c90°畴，其界面平行于[010]或[001]，相应的位移矢量为〓方向。

Diagnosis was based on clinical suspicion, confirmed by histology or ophthalmoscopy for all spontaneous forms and for most iatrogenic cases.

The main purpose lies in forming the spontaneous polarization vector with neighboring opposite periodic structure.

畴工程操作的目的在于形成自发极化矢量相邻相反的周期性结构。

Preterm labor can be more accurately predicted by combination detection of plasma P-LAP and IL-6. The oversecretion of IL-6 may lead to the decrease of P-LAP, which may be the key factor for spontaneous preterm labor.

对有自发性早产先兆的孕妇进行P-LAP和IL-6联合检测，能更准确地预测早产；IL-6等促炎症细胞因子分泌增多，导致P-LAP水平下降，可能是自发性早产的关键因素。

The decision was inspired by a spontaneous opera performance by the BBC at London's Paddington Station in 2004, the paper said.

报导指出，他们是看到二OO四年英国广播公司在伦敦柏丁登车站安排了一场即兴歌剧演出后，有了这个灵感。

Some of them with visual loss, optic papilledema and orbital mass. B-scan ultrasonography revealed a cyctic tumor and a strong echo spot with spontaneous movement. On CT scanning, found was a well-defined hyperdensity mass in which there was a low density area. On MRI, the signal intensity of T1WI of cystic fluid was low or moderate and of T2WI was high, while the signal intensity of T1WI and T2WI of surounding scar tissue was still low.

结果 22例有反复的眶内炎症史及占位性病变体征，如眼睑及结膜充血水肿，眼球突出，眼球运动受限；6例有视力下降和视乳头水肿，并扪及肿物。B超示占位性病变内有液性暗区及自发运动光斑；CT扫描示高密度块影中央部有低密度区；MRI检查示囊液信号强度T1WI为低或中信号，T2WI为高信号，其周围的纤维瘢痕组织T1WI和T2WI均为低信号。
