This special heat-treatment ensures full bearing performance and prevents the set screws from loosening during operation as the set screws can be tightened hard enough without causing broken inner ring set screw hole.

内圈螺钉孔周围经局部高温回火后，轴承获得更好的性能，可防止螺钉在轴承工作期间松脱，同时螺钉拧得紧也不会导致内圈爆裂。

Double Circle Fence, also known as double-lap Fence, which uses 2.5mm cold-welded together, after drawing, each horizontal wire mesh has a curved arc to increase the strength.

双圈护栏网又称为双圈隔离栅，它采用2.5mm 冷拉丝后焊接而成，每个网孔的横丝有一个弯弧，以增加强度。

Screening of thermal stabilizers for HRPHRP powder was dissolved in distilled water and mixed with additives. Aliquots of enzyme solution were added to a microplate and incubated in the air under thermal stress or room temperature.

HRP热稳定剂的筛选：HRP干粉用双蒸水溶解(0.1μg/mL)，与作为酶稳定剂的各组分以一定比例混溶后，于96孔板中点样，在加热或室温条件下的空气中存放。

Methods The 3-5 generation fibroblasts were inoculated in 24-well with rat-tail collagen. A denuded area was made when the 3 generation of the fibroblasts was influent into a monolayer. Cells were then exposed to the presence of various concentrations of viper venom, mitomycin C, and the cells migrated into the denuded area were counted evely 6 hours.

将培养的第3~5代人结膜下成纤维细胞接种于涂有鼠尾胶原的24孔板中，待细胞生长融合后在培养板上划线，造成无细胞的裸露区，分别加人不同浓度的蛇毒制剂、丝裂霉素C及二者的混合液，每6h观察记录移行至裸露区的细胞。

Leakage in the initial observation to determine the basis of the leakage site, and then manually set car observation, if the leakage were no significant changes in static and dynamic sealing ring problem; such as the disk when there are significant changes in leakage can be concluded that the dynamic , static friction ring problems; such as leakage of medium along the jet axis, w你好le moving most of Central ring problems, leakage to the surrounding medium or from the water spray cooling holes in the leakage, the seal ring for static failure.

杂质泵安装静试时泄漏机械弥缝安装调试好后，一般要进行静试，察看泄漏量如泄漏量较小，多为动环或静环弥缝圈存在问题；泄漏量较大时，则表白动、静环磨擦副间存在问题在开端察看泄漏量、判断泄漏部位的根蒂根基上，再手动盘车察看，若泄漏量无明显变化则静、动环弥缝圈有问题；如盘车时泄漏量有明显变化则可下定论是动、静环磨擦副存在问题；如泄漏介质沿轴向喷洒，则动环弥缝圈存在问题居多，泄漏介质向四周喷洒或从水冷却孔中漏出，则多为静环弥缝圈失效此外，泄漏通道也可同时存在，但一般有主次区分，只要察看细致，认识结构，一定能正确判断

For maximum security, pass the loose end back out through the top left eyelet, then tie it off with a simple loop knot as shown in the One Handed Shoelace Knot .

最大的安全性，通过松散结束后通过左上角孔，然后配合它关闭以一个简单的环结所显示的一个双手鞋带结。

Methods Retrosigmoid sinus approach was adopted to find the cerebellopontine angle. The area surrounding the jugular foramen was explored carefully under microscope and the glossopharyngeal nerve was cut off. The superior branch of vagus nerve should be cut off simultaneously in patients with earache and the space-occupying focus should be cut off to receive pathological examination.

采用经乙状窦后入路进入小脑脑桥角，在手术显微镜下对颈静脉孔周围进行探查并切断舌咽神经根；伴有耳痛者同期切断迷走神经上支；如发现占位病灶须切除病灶并行病理检查。

Chiari malformations are a spectrum of anomalies associated with a reduction of posterior cranial fossa volumes and CSF while conserving overall brain volume. Chiari I malformations refer to a greater than 5 mm herniation of the cerebellar tonsils down through the foramen magnum.

chiari畸形是由于后颅窝容积及脑脊液减小而与正常的脑容积不匹配造成的一系列的异常病变的统称。chiariI型畸形是指小脑扁桃体下疝超过枕骨大孔5mm以上。
