简介中文名称：低电压保护 英文名称：under-voltage protection 定义：预定当被测量点的电压低于规定值时执行相应保护动作的保护方式。 应用学科：电力（一级学科）；继电保护与自动化（二级学科） 低电压保护指用低压保护继电器并连在电源两端，当低电压时会自动脱扣从而分开断路器开关。 　低电压实习安装：有热继电器，熔断器，中间继电器等低电压设备。独特的价值点是USP营销理论的延生，要求品牌运动必须向消费者提供一个“独特的价值主张”。它有以下三方的特质： 每一个品牌都要传达一种价值主张。 这种价值主张是独特的。 这种价值主张能有效推动品牌的销售以及品牌资产的提升。

管螺纹是位于管壁上用于连接的螺纹,行管道的连接，使其内外螺纹的配合紧密

常见的管螺纹主要包括以下几种：NPT、PT、G等。

1）NPT是National(American)Pipe Thread的缩写，属于美国标准的60度椎管螺纹，用于北美地区，国标查阅GB/T12716-1991。

2）PT（BSPT）是Pipe Thread 的缩写，是55度密封圆锥管螺纹，属于惠氏螺纹家族，多用于欧洲及英联邦国家，常用于水及煤气管行业，锥度1:16，国标查阅GB/T7306-2000。国内叫法为ZG.。

3）G是55度非螺纹密封管螺纹，属惠氏螺纹家族。标记为G代表圆柱螺纹。国标查阅GB/T7307-2001。

倒模工艺开始之前，必须准备好PDMS溶液。由于PDMS在室温下不能固化，所以要添加特定的固化剂。PDMS溶液是通过将PDMS预聚物和固化剂以10:1的质量比混合制备的。在充分搅拌后，混合物中出现大量的气泡，并在真空桶中抽空（也可放置40分钟以上），直到混合气体完全被抽走。然后将先前准备好的平面微透镜阵列模板连接到离心机上，将少量的PDMS溶液慢慢倒在微透镜阵列上，让其慢慢散开并去除任何气泡，相应调整离心机的速度和时间。为了获得厚度均匀的PDMS网板（使用较厚的PDMS网板是为了防止在随后的负压过程中薄膜下垂），这里再次使用了多次旋涂的方式。在涂抹单层后，让薄膜静止约1分钟，然后进行软烘，在加热前寻找气泡，如果气泡没有完全排出，在加热过程中就会形成气泡。一旦旋涂过程完成，薄膜就在65℃的烘箱中烘烤2小时。最后去除薄膜，得到一个厚度约为450微米的柔性PDMS模板，其凹陷的微透镜阵列与微透镜阵列的形状相反

首先依次组装主体和可拆卸式盖子，然后将模具安装在防震台上。然后将柔性PDMS阴性膜连接到加工成顶盖的球状缺陷的顶部，然后放置并连接微流注射腔室。连接一个真空泵进行抽气，此时，柔性PDMS模板在负压下下沉，并与盖子紧密贴合，形成我们需要的弧度。这里的微孔阵列设计允许在PDMS网板上施加更均匀的力，使负压均匀地分布在网板上，并使薄膜拉伸的各向异性降到最低。负压稳定后，毛细管与微流控注射泵（LSP04-1A，朗格恒流泵有限公司）连接，进行粘合。通过微流控注射室的粘合孔和通气孔固定一定量的过量，以有效清除可能存在的空气和杂质。最后，整个装置被置于紫外线设备下，一旦模塑材料固化，它就被脱模，以获得弯曲的微透镜阵列。

设计中选择的成型材料是NOA81（Norland Optical Adhesive 81，Norland Products Inc.），它具有优良的光学透光性，在可见光波长中保持90%以上的透光率，并且具有高度的耐溶剂性，完全固化后硬度不脆。由于其弹性，该结构能够缓解由振动或环境温度的极端变化引起的应力，从而确保固化的复眼结构的长期性能。此外，在紫外光下的固化速度极快，最快的紫外固化在几十秒内完成，这对保护紫外光刻设备非常重要。

“AW“是“Airwatts“的缩写，意思是，空气瓦特或者空气瓦茨。

AW吸力叫气动功率产生吸力。

计算公式是Airwatts（AW）=真空吸力inches of water*空气流量cfm/8.5。

“拓展资料”：

AW吸力叫气动功率产生吸力，KPA吸力通常来表示吸尘器的吸力大小。

在吸尘器中，如果想测试吸尘器持续工作能力，需要用AW值表示，KPA表示不了，像戴森吸尘器跟其他的吸尘器不同的就是只标注了AW值。

吸尘器衡量指标还有：功率（瓦)，吸入功率（瓦）,流量（升/分 L/Min)

Kpa是机器产生负压的大小, 吸尘器是产生真空负压 英文为vacuum cleaner.
