查询词典 orbital

The sulphur atom in the intermediate has sp2 hybridization, and the remaining p orbital is symmetrical to the d orbital of the metal center. Thus, the lone pair on the p orbital can have interaction with the d orbital to form a π bond, which leads to the coplanarity of the center of Cp ring, Ru, P, S and Si atoms, rather than the deviation of P, S and Si atoms from the plane.

该中间体中，硫原子采取sp2杂化，硫原子剩余的一个p轨道与金属中心上的d轨道具有相同的对称性，因而该p轨道上的孤电子对可与金属中心上的d轨道形成π键，导致Cp环中心， Ru， S1， P和Si原子在同一平面内，而不是S1， P和Si原子偏离该平面。

It is found that the nature of the interaction between CO and Pd(110) surface by population analysis and DOS analysis what the 5σ orbital of CO and the d orbital of metal formed electron donation; and the 2π* orbital of CO and 4s and 3d orbital of metal formed electron back- donation.

通过布居数分析和态密度分析发现， CO 和 Pd(110)表面的相互作用，主要是 CO 的5σ轨道和金属原子的 d 轨道形成5σ-d 配位键；同时 CO 的2π*轨道和金属原子的4s 和3d 轨道形成反馈键。

The results show that the sturcture of each of Tin clusters is obtained by capping one Ti atom to the Tin-1. The Natural bond orbital analysis show that the 4s , 4p, 4d orbitals hybridizes with 3d orbital, and about one electron transfer from 4s orbital to 3d orbital. Moreover, the electrons also transfer between different atom. The results also indicate that the average bond length of clusters were determined by the 4d and 3d orbitals except Ti7. But for Ti7, the average bond length only depend on 3d orbital.

研究结果表明： Tin(n=2~7)团簇都依带帽的形式在前一个团簇的结构基础上加一个原子变化而来；通过自然轨道分析发现，团簇原子的轨道存在sp-d杂化，有大约一个电子从4s转移到了3d，原子之间亦存在电子转移，而且除Ti7外，团簇键长由最外层4d轨道电子和3d轨道共同决定，在Ti7中，团簇键长由3d轨道决定。

Diplopia and disturbance of ocular movement are related to the incarceration of the extraocular muscles and the displacement of orbital wall, and the management is simple relatively. However, the treatment of enophthalmos is difficult because the orbital reconstruction is made to be complicated by the complex morphous of orbital wall and the limited operative area. This study introduced the use of CAD/CAM technique in orbital reconstruction, and the result is more satisfactory than traditional methods.

眶壁重建是其矫治的首要条件，然而，眶壁形态复杂，并有视神经由眶尖通过，加之术野受限，使精确的解剖复位很难完成，本文应用CAD/CAM技术，术前成型钛网并行眶壁重建，通过CT分析和眼科检查，证实该技术在眶壁重建的精确性上均较传统方法有明显提高，其中，眶内壁的修复程度和眶底修复形态的对称性，以及眶容积缩小程度反映了其形态修复的精确性，而置入深度则体现了在缺损修复范围设计中的优越性。

However, the therapeutic efficacy is not ideal yet. There were 5 cases remained at least 3 mm enophthalmos postoperatively. The analysis of the CT data indicated that the insufficient compensation of orbital volume should contribute to the remained enophthalmos. The titanium mesh prebent with the aid of CAD/CAM technique can provide precise orbital reconstruction but can not increase the orbital volume sufficiently because of its limited thickness.

与此相应的是，该技术在术后眼球突度和复视恢复程度上，也较传统方法有所提高，然而，其治疗效果并不十分满意，8例患者中有5例在术后仍有超过3mm的眼球内陷，这一方面是由于该组病例创伤相对较为严重，另一方面，我们通过术后CT分析认为是由于眶容积补偿不足造成的，这是因为钛网的厚度有限，即使达到了精确的眶壁重建，其自身厚度也不足以补偿因脂肪液化、萎缩所造成的眶容积损失。

Methods: A little improvement was made on the management of orbital septum and septal fat while doing the general lower eyelid blepharoplasty. Separate the plane between them. Orbicularis oculi and orbital septum to the infraorbital marginalis, incise the orbital septum transversely, then sewing up the orbital fat onto the periosteum of the infraorbital marginaslis in order to fill up and correct the sunken deformity of this area.

在进行常规的睑袋整复术同时，对眶隔和眶脂的处理作适当的改进，在眼轮匝肌下平面分离到眶下缘，横向切开下睑眶隔筋膜，将眶脂缝合在眶缘的骨膜上，填充和纠正该区域的凹陷畸形。

AIM: To discuss the operative opportunity and surgical approach on patient with eyeball atrophy and complicated fracture of orbital maxillary zygomatic caused by severe eyeball rupture to solve eyesocked depression, face abnormality or restriction on opening of mouth on wounded side and trismus and so on caused by above reason.

目的：探讨重度眼球破裂伤后眼球萎缩合并眼眶—上颌骨—颧骨（orbital maxillary zygomatic OMZ）骨折手术时机及手术方式，解决由于上述原因所致的眼窝凹陷，伤侧面部畸形，开口受限等。
