B、NC型横流式冷却塔淋水填料马利NC方形横流式冷却塔采用的MX-75型高级薄膜式复合波淋水填料, 堪称世界上薄膜式淋水填料的佼佼者,此填料片用于横流冷却塔, 由热处理PVC多层片构成，厚度0.38mm, 表面成波纹式, 相邻两层填料片形成的间隔,保证气流的通畅,经美国冷却塔协会(CTI)测试分析,其阻力特性和热力特性远远优于现有国内填料,使用寿命15年以上。
一般冷却塔产品填料均采用竖直放置，且无明显收水端。
参考右下图，一般冷却塔的做法是布水盘偏向外侧安装，A、B、C、D、E、F这6个区域内充满了填料，而当冷却塔运行起来以后，由于风机向上排风，气流由外向内流经填料，在风力的带动下，实际冷却水流过的区域是C、D、E、F、G这5个区域，A、B两区无水。
那么按照一般冷却塔的做法，用，而有水的G区却又没有填料。
马利的工程师们对这个问题进行了深入的研究，在千百次的实验之后，提出了冷却塔填料倾斜悬挂式安装的方案，在马利冷却塔当中C、D、E、F、G区充满填料，A、B两区无填料，而倾斜的角度又根据不同的塔型有十分严格的要求，这种方法有效地解决了进风面下端“无水区”问题，且填料带有明显的收水端，克服了竖直放置填料的缺点。

纤细外壳的直线光栅尺
纤细外壳的直线光栅尺主要用于安装空间 有限的地方。如果使用安装板或固定元件， 可实现较大测量范围和支持更高加速度 载荷。
绝对式直线光栅尺 • 玻璃光栅尺
高重复性增量式 直线光栅尺 • 钢光栅尺 • 信号周期小
光栅尺栅距越小，光电扫描的衍射现象越严 重。HEIDENHAIN公司的直线光栅尺采用两 种扫描原理：
• 成像扫描原理，用于20 µm和40 µm栅距 光栅尺。
• 干涉扫描原理，用于栅距8 µm甚至更小 光栅。
成像扫描原理 简单的说，成像扫描原理是采用透射光生成 信号：栅距相同或相近的光栅尺和扫描光栅 彼此相对运动。扫描光栅的基体是透明的， 而作为测量基准的光栅尺可以是透明的也 可以是反射的。
带距离编码参考点光栅尺或编码器，其绝对 参考点位置通过累计两个参考点间信号周 期数并用以下公式计算：
