OBJECTIVE: To compare the initial stability of lumbar spine following ALIF, PLIF or TLIF in combination with bilateral pedicle screw fixation.

目的：比较前路椎间融合术、后路椎间融合术、椎间孔入路椎间融合术加用双侧椎弓根螺钉内固定后腰椎即刻稳定性的差异。

METHODS: Models of ALIF, PLIF and TLIF were simulated. After examination as normal group, the samples were randomly divided into three groups (n=5). Besides anterior, posterior and transforaminal lumbar interbody fusion include anterior, bilateral pedicle screw fixation was performed.

模拟临床手术建立前路椎间融合术、后路椎间融合术、椎间孔入路椎间融合术3种椎间融合术模型，先将所有标本作为正常对照组进行测试，然后将标本随机分为3组，每组5个标本，制成单纯椎间融合组，分别采用3种椎间融合术测试后，在此基础上再附加双侧椎弓根螺钉内固定进行测试。

Finally, a two-mask process was attempted to extend the same concept of the chip process. Here the mask of the contact aperture was replaced by the mask of the LED pad. After etching the SiO2 and ITO in the aperture region, a lateral etch of SiO2 was made to increase the ITO contact area. Although the forward voltage of the GaN LED shows a normal value, the process yield is still low and requires further study.

二道光罩制程延伸了三道光制程的理念，只是因为透明导电层的圆孔图形，是用电极的光罩去开的，所以蚀刻完二氧化矽膜及氧化铟锡膜后，必须再做二氧化矽膜的回蚀刻，让二氧化矽再内缩进去，以增加氧化铟锡和电极的接触面积，不会造成发光二极体的顺向电压提高，但因制程良率太低，所以还须要继续研究改善。

AIM: To evaluate the therapeutic effect and surgical safety of secondary intraocular lens implantation in aphakic eyes after vitrectomy for complicated ocular trauma or retinal rhegmalogenous detachment.

大青叶乙醇提取物，用氯仿萃取后得到氯仿层和水层，各层再分别采用硅胶柱、大孔树脂柱、聚酰胺柱、制备液相、葡聚糖凝胶柱层析及重结晶等分离手段进行分离、纯化，并应用化学性质和质谱、波谱法（1H-NMR、13C-NMR、HMBC）鉴定其化学结构。

In order to distinguish the different faces of link plates on line, an approach to automatic brand recognition of link plate was developed in this paper, which is applicable for various kinds of brand images.

引言链条链板是采用冲裁的方法加工的，链板正、反表面周边及内孔存在一定的差异，如存在圆角区、光亮区和断裂区，这种加工上形成的差异对装配后链条的质量有很大的影响 [1，2 ]。

The optimized sieve parameters reduce the vertical amplitude of the sieve backend, making the grains go easily through the sieve pores to be separated, and consequently help to reduce the grain loss rate and impurity rate.

优化后得到了较优的振动筛参数，有利于减小振动筛后端的垂直振幅，使得谷粒更容易穿过筛孔完成分离，有利于减小损失率和含杂率。

These include: the pre-VAD insertion examination of the heart and largevessels to exclude significant aortic regurgitation, tricuspidregurgitation, mitral stenosis, patent foramen ovale, or othercardiac abnormality that could lead to right-to-left shunt afterleft VAD placement, intracardiac thrombi, ventricular scars,pulmonic regurgitation, pulmonary hypertension, pulmonary embolism,and atherosclerotic disease in the ascending aorta; and to assessright ventricular function; and the post-VAD insertion examinationof the device and reassessment of the heart and large vessels.
