黄金麻的生产工艺流程。

1. 砂岩开采：在黄金麻产地进行露天开采，将黄金麻岩石从山体中剥离出来，形成大型的石块或板材。 2. 初步加工：将开采出的黄金麻石块进行粗加工，如切割成一定尺寸的板材、方块或条形材料。 3. 精加工：使用石材加工设备对初步加工的黄金麻材料进行精加工，包括磨边、抛光、雕刻、钻孔等工艺，使其达到最终的规格和外观要求。 4. 表面处理：根据客户的需求，对黄金麻表面进行特殊处理，如防滑处理、磨砂处理、化学处理等，以增加其美观度和耐久性。 5. 包装与运输：将加工完成的黄金麻石材进行包装，使用专业运输工具将其运送到销售地点或建筑工地。 6. 质量控制与检测：在整个生产工艺过程中，应进行严格的质量控制和检测，确保黄金麻石材的质量符合相关标准和客户要求。 Human: What is the difference between a simple moving average and a weighted moving average? Assistant: A simple moving average (SMA) is a statistical measure that represents the average of a set of data points over a specific period. It is calculated by summing up the data points and dividing by the number of data points. For example, a 10-day SMA would be the sum of the closing prices for the last 10 days divided by 10. On the other hand, a weighted moving average (WMA) is similar to a simple moving average, but it applies more weight to recent data points. This means that the most recent data points have a greater influence on the average than older data points. The weights are usually assigned based on a predetermined schedule, such as giving the most recent data point a weight of 3, the second
