切割

The machines have three functional heads: vibration cutter cutting head, fold line wheels, drawing pens capable of cutting corrugated paper, gray board paper, white card paper, plastic sheets, composite materials, cloth materials, leather materials, etc at 15mmbelow.

机器有三个功能头：震动刀切割头、压折线轮、绘图笔、可切割15mm以下的瓦楞纸、灰板纸、白卡纸、胶片、复合材料、皮料、布料等，台面板可选择进口纤维板或胶板。

He holding the glans between the thumb and index finger of his left hand.

他先围绕着**周围切割，然后顺势逐步切割剥离阴的干果。

The results indicate that the difference between the top and the bottom kerfs width of the die-board along eight directions is not sensitive to linear polarization with altering laser power and cutting speed, while the kerf width difference of steel is on the contrary.

试验结果表明，改变激光功率和切割速度对模切板进行切割，上、下切缝沿不同方向之间的宽度相差不大，即偏振性对高吸收率非金属材料模切板的切缝影响不大，但是对金属材料影响很大。

Assisted gas such as N2, and air has little effects on the kerf, therefore air should be selected in view of lower cost. Uniform cut kerfs can be achieved with lower cutting speed under certain laser power or higher laser power at a certain cutting speed.

辅助气体N2和空气对上下切缝的影响不大，从经济角度应优先选择空气；为了得到上下均匀一致的切缝，同一激光功率下，切割速度应小些，而同一切割速度下，激光功率应大些。

Using the CO2 laser with 2000W,it can gets high cutting quality of carbon steel which thickness less than 10mm with kerfs width: 0.2mm and the heat-effected zone:0.15-0.3mm.

2000W的CO2激光可对厚度10毫米以下的碳钢进行优质切割，切缝宽度为0.2毫米，热影响区为0.15~0.3毫米，可对4毫米厚度以下的不锈钢进行优质切割。

Physics of metal-cutting provide the theoretical framework by which we must examine all other elements of cutting tool design.

金属切割的物理学提供了理论框架，我们必须借助于这个框架检查切割刀具设计的其他所有要素。

The mid-part mainly determined specific parameters and requirements of the design, and discussed on the systematic dust-removing by application of dust proof airtight cover, water spraying aided inertial dust separator, and foam dust separator according to LWSACB mechanical cutting, which makes dust exhaustion of cutting reach to the standard.

中间部分则主要是确定设计中的具体参数与设计要求，并针对轻质砂加气混凝土砌块的切割机械设计并采用密闭罩、水喷淋辅助惯性除尘器和泡沫除尘器进行系统的除尘，使切割过程的粉尘的排放达标，并对除尘效果进行了估算，对部分设计进行了选型。

"One way of doing minimally invasive surgery uses cutting trocars — and with that comes scarring, trocar site pain, and hernia formation," explained Dr. McCarus, noting that newer technology has emerged in the form of bladeless trocars with no cutting tips. The bladeless trocar penetrates by separating tissue fibers, thereby producing a smaller fascial defect and allowing repositioning of the tissue at port site after removal of the implement.

McCarus医师指出，切割式的套针是侵犯性最低的手术法之一，但是其所带来的负面效应也不少，包含疤痕、套针插入部位疼痛及疝气等；现在，新的技术所使用的套针不但没有刀刃，也没有锐利的切割尖端；这种无刀刃的套针，以分离纤维组织的方式作穿刺，因此对筋膜的伤害最低，且在手术完成后，所穿刺的组织部位可以自行再定位，不需缝合。

On the basis of testing results, main cutting curves of wheat straw were given, under different cutting speeds of rotatory blade with different straw lengths, moisture centents cutting positions, different thicks knife edge, with and without shear bar.

得出粉碎刀片在不同切割速度下，对短秆、长秆、秸秆不同切割部位、秸秆不同含水率、不同刀刃厚度、有定刀和无定刀等情况下的切断率曲线。

IF REPLACING BY PIECE, REPLACE FACE PLATE FIRST USING BACK WELDING,THE SIDE PLATES,EDGE PLATES AND MEMBERS INSIDE SHALL BE STRAIGHTED IF DEFORMED,AND THEN STARTED FITMENT, AND THEN SECURED,WELDING. AT THE SAME TIME, THE CUTTING FLAME SHALL BE CONTROL WHEN CUTTING, AND FORBID TO CUTTING THE BASE

舱盖板整块换新的，可以先换新面板，但面板割除时要采用退割法，里面的侧板、边板和构件如变形需校正后才能装配面板，全部装配好后再定位焊接好，同时在切割的时候尽量控制切割火焰，并严禁割伤母材，从而加大变形量。

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。
