切割

Methods: Vitrectom was performed on49 patients (49 eyes) diagnosed as vitreous hemorrhage. 25 patients(25 eyes) with ocular injury,9 patients (9 eyes) with diabetic retinopathy, 11 patients(11 eyes) with central retinal vein occlusion, 2 patients (2 eyes)with rhegmatogenous retinal detachment, 1 patient (1 eye) with retinal vein periarteritis, 1 patients with senile macular degeneration.

应用玻璃体切割术治疗玻璃体积血49例（49眼），其中眼外伤25例（25眼），糖尿病性视网膜病变9例（9眼），视网膜中央静脉阻塞11例（11眼），孔源性视网膜脱离2例（2眼），视网膜静脉周围炎1例（1眼），老年性黄斑变性1例（1眼），49例患者均行经睫状体平坦部闭合式巩膜三通道玻璃体切割术。

Objective To discuss the value of percutaneous biopsy of pulmonary permeative pathological changes. Methods The pathological change was performed after getting the tissue by the groove needle punctured the lesion under CT guided.

The frequency of particular amino acids in signal peptides by statistical approach was 48.54% for hydrophobic, 18.67% for uncharged, 24.54% for negative and 8.00% for positive amino acids. The most frequent amino acid was alanine, and the least was isoleucine. Three classes of signal peptides were found in the genome of P. syringae pv. tomato, 501 ORFs belong to secretary signal peptides, 36 ORFs belong to twin-arginine signal peptides, and 15 ORFs belong to lipoprotein signal peptides. Type IV pilin signal peptide and bacteriocins and pheronones signal peptide was not found in the genome.

同时，对组成信号肽的氨基酸种类作了系统的分析，发现组成信号肽的氨基酸中非极性氨基酸占48.54%，极性氨基酸占18.67%，带负电荷氨基酸占24.54%，带正电荷氨基酸仅占8.00%，出现最多的3种氨基酸依次为亮氨酸、丙氨酸和丝氨酸，最少的氨基酸是异亮氨酸，在切割位点－1端的氨基酸中83.21%均为丙氨酸，在切割位点后3位的氨基酸中最多的氨基酸也是丙氨酸。

First, he had it recut, reducing it from 35.52 to just over 31 carats, to eliminate the chips and "bruises" inevitable in a stone of its age but also to improve its clarity, brilliance and grade.

首先，他把它送去重新切割，从原本的35.52克拉切割成31克拉多一点，切掉钻石因年代久远不可避免的小裂痕和「碰伤」，却也提高了它的净度、亮度和等级。

The visual acuity was light sensation, hand move, counting f ingers/10cm and 002 in 1 eye respectively. 12 eyes can not meet visual inspection, the reflection of strong light was not obvious.13 eyes underwent lensectomy and anterior vitrectomy, 1 eye was implanted intraocular lens, 3 eyes with retin al detachment underwent lensectomy, vitrectomy, photocoagulation, gas tamponade and scleral buckling.

手术前视力1只眼为光感，1只眼为眼前手动，1只眼为数指/10 cm，1只眼为0.02，12只眼不能配合视力检查，对强光刺激反应不明显。13只眼行晶状体切除和前段玻璃体切割，1只眼1期植入人工晶状体， 3只合并视网膜脱离眼行晶状体切除、玻璃体切割、眼内激光光凝、注气、巩膜环扎手术。

Sanjay Kambne has been performing this work for years. He says he has to be very careful while working with the stones.

Sanjay Kambne 从事切割钻石工作很多年，他说，他在切割钻石时必须非常细心。

A high cutting efficiency required the acid environment and urea as a solutizer had an advantage over 70% formic acid in facilitating cleavage.

高效率的切割需要在酸性条件下进行；以尿素作为促溶剂比70%的甲酸更有利于小肽的切割。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
