The results show that, by the way of optimizing preparation condition, the spherical zirconia powders with suitable particle size distribution are prepared using chemical precipitation method. Using heterogeneous chemical precipitation coating technique, the sph, erical nickel coated zirconia powders are prepared and the heterogeneous nucleation can be done on the surface of spherical zirconia powders. The thickness of coated layer, homogeneous degree and crack of surface can be controlled by the way of controlling powder concentration, adding rate of reactants feeding and adding surface active agent.

研究表明，采用化学沉淀法，通过优化制备工艺条件，可以制备粒径分布较均匀的球形氧化锆粉体；利用非均相化学沉淀包裹技术制备的金属镍包裹氧化锆微球粉体，球形氧化锆颗粒表面作为异相成核的场所，通过控制颗粒浓度、加料速度以及添加表面活性剂等工艺条件，可以调控包裹层厚度、表面均匀度以及表面裂纹等。

For those mastering above 2200 strands, the etheric is called into the physical in roughly 8 months time.

那些掌握了2200股以上的成员，以太层在大概8个月的时间被召唤成实相。

南珠的形成：南珠是珍珠贝科动物中马氏珍珠贝受刺激物刺激后，外套膜的部分细胞所分泌的壳角蛋白膜和碳酸钙的结薄层交互重叠，围绕着刺激物沉积而成的圆形或其他形状的物体。

This process substantially corresponds to the use of an amplifier foil in extraoral radiography.

这一工艺充分对应口外X光摄像中放大器箔片的使用。X光首先转换成荧光层中的可见光。

The 3D reconstruction could display the changes of the chiastopic fusion of different nerve functional fascicular groups directly. It could extract alone, merge and combine arbitrarily

基于二次成像技术和Photoshop 图像处理软件图层处理技术的计算机自动配准可应用于长段周围神经的三维可视化重建，重建快捷，效果较好。

In addition, the abundant microcracks developed around the cavities provided the passages or vents not only for gases escaping like CO2, but for Ca(superscript 2+), Al3(superscript 3+), released out of the feldspathic minerals from the intrusion, migrating into the cavities as well.

Ca(上标 2+)、Al(上标 3+)离子在孔洞、孔隙溶液中发生化学反应，逐渐生成浊沸石、方解石，并逐渐沉积生长成集合体，生成浊沸石后的岩体可成为油气储层。

The femorotibial cartilage thickness was determined in BL and follow-up MR images across five tibial and three femoral subregions in the medial/lateral compartment, respectively.

在BL和随访MR成像中分别通过内侧和外侧层中5个胫骨和3个股骨亚区确定胫股软骨的厚度。

Objective:To assess the value of high-resolution 3D contrast-enhanced MR angiography(3D CE MRA)in the diagnosis of renal artery fibromuscular dysplaisa.

目的：评价高分辨力三维增强磁共振血管成像术(3D CE MRA)诊断肾动脉纤维肌层发育不良的价值。

In four patients with bilateral total corneal stem-cell deficiencies, 3-by-3-mm specimens of oral mucosal tissue were harvested, and the harvested cells were cultured for two weeks with 3T3 feeder cells that had been treated with mitomycin C. Conjunctival fibrovascular tissue was surgically excised from the ocular surface, and sheets of cultured autologous cells were transplanted directly to denuded corneal surface of one eye of each patient, without using sutures.

在4位双侧干细胞完全缺失的病患，取下3乘3的口腔黏膜组织样本，而且被取下的细胞与使用3T3细胞铺成的细胞层以mitomycin C处理，共同培养2个星期；结膜纤维血管组织利用外科从角膜表面切除，而且培养的自体细胞直接地移植到每位病患一只眼睛裸露的表面，不需要缝合。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
