Given the same total flow effusion from holes, the results show that the heat shield gets a higher average cooling effectiveness when the opening ratio is 3% compared with 6%; cooling effectiveness is sensitive to the height of ripple board, the heat shield gets the highest cooling effectiveness when the dimensionless height of ripple board is 1% compared with 2% and 3.33%; but there is a little influence on the cooling effectiveness of the liner with the change of the diameter of holes and the height of cooling passage.

研究表明：在气膜孔出流总量相同的情况下，3%开孔率比6%开孔率的隔热屏平均冷却效率较高；波纹板高度对隔热屏冷却效果影响较大，波纹板无量纲高度为1%比波纹板无量纲高度为2%和3.33%的隔热屏平均冷却效率高；孔径和冷却通道高度的改变对隔热屏冷却效果几乎没有影响。

No US-pin plastic treatment therapy, a comprehensive alternative to traditional plastic injection of the United States (with the needle and micro-needle) is efficient, non-invasive and safe,"mesoderm into beauty therapy" is the latest technology of water use and water channel protein electrophoresis principle of development Note the infiltration hole electric technology to non-needle injection principle, the use of "point to a plane," AMD permeation technology in skin electroporation Act under the influence of pulsed current stimulation, so that pores have a physical reaction to the rapid spread in two seconds 650-800 of fine pores, forming an instant electronic delivery channels of nutrition, nutrition Note dialysis therapy immediately with electrophoresis, soft laser stimulation and ice, etc., in the most secure and fast, the skin will be required for nutritional products , 99% transmitted to the basal cells, and can be stored as long as 72 hours, the skin smooth and more compact, creating a perfect Beautiful Skin.

B。电穿孔技术：直接作用于皮肤，瞬间增强皮肤组织的可渗透性。在电击的作用下，细胞的脂质二重层上形成电击孔。在电击孔形成的同时，使得原先无法被细胞吸收的亲水性分子能够穿透并进入细胞内部。电击孔一旦形成，则根据电击的长度，在数秒种至数分钟之内保持打开状态。C。电渗透技术：电渗主要作用于将要分散的物质分子，帮助其顺利穿透并进入肌肤内部，性质相同的电荷相互排斥，因此对正极的营养分子施加正电流，可将营养分子推入皮肤组织。此时，中性分子也一道穿透并进入肌肤内部。

The metal chip has tiny holes on one side, the transparent basis material has microdots matching to the holes, and be combined with the tiny holes tightly.

Experimental results show that, using the UV-LIGA process, hexagon micromesh nickel sieves (200 μm in side length, 50 mm in diameter and 120 μm in thickness) with an open-area percent of 88% and a sheet-thickness of 120 μm, which can hardly be achieved by the conventional machining methods, are successfully machined. The machined sieves are characterized by their smooth surfaces and aperture walls, high precision sizes as well as rigid and homogeneous structures.

结果显示，采用优化的工艺条件（前烘65℃/20min，95℃/20min；适量曝光剂量；后烘65℃/10min，95℃/15min；匀胶后静置、随炉冷却；超声辅助显影等）所制备的六边形镍网（边200μm），不仅开孔率高(88%)，厚度大(120±3μm，且具有尺寸精度高（形位误差±2μm）、孔形一致性好（筋宽偏差＜3μm）、孔壁平滑等特点。

Rotary valve spool also have different shapes, for example, for the traditional butterfly valve plate, the dynamic contour valve plate; O-shaped hole for ball valve, V-shaped opening, and Modified hole structure.

Angle valve spool stroke also have different shapes, for example, for the traditional butterfly valve plate, the dynamic contour valve plate; The O-shaped hole for the ball valve, V-shaped hole and amendment type structure openings.

角行程阀的阀芯也有不同形状，例如，用于蝶阀的传统阀板、动态轮廓阀板；用于球阀的O形开孔、V形开孔和修正型开孔等结构。

In the jig design process, mainly locates by V shape block and the support plate, depends on the straight clamp and the spring clamps, drills turns diameter two to be supposed to use long trades quickly drills the wrap, when drills turns the diameter incline hole uses the plane incline the jig body, when drills turns the diameter incline hole uses is the horizontal-type drilling machine, when face milling 2 V shape blocks and the milling cutter cannot interfere ,therefore V shape block altitude must reduce, the jig design must be convenient, be simple.

在夹具的设计过程中，主要以V形块和支承板来定位，靠直压板和弹簧来夹紧，钻拐径两孔应采用长型快换钻套，在钻拐径倾斜的孔时采用平面倾斜的夹具体，在钻拐径倾斜的孔时使用的是卧式钻床，铣面时2个V形块与铣刀不能干涉，因此V形块高度要降低，夹具设计要方便、简单。

Objective To introduce the diagnosis and local injection treatment of the obturator nerve neuralgia. Methods 4 cases with 5 sides of certain diagnosed obturator nerve neuralgia in out patient department were selected and 3 of them treated by local injection of prednisolone plus local anesthetic to the nerve where it emerges from the obturator canal.
