另一方面，如果可能，一个物理模型以符合产品要求的方式，并且按初始比例简化，以便使任何人都能在设计和造型上做出正确的评价。
On the other hand, if possible, a physical model to meet the product requirements, and according to the initial ratio of simplified, so that anyone can design and modeling of the correct evaluation.
由于 P 波和 S 波以不同但相当恒定的速度传播，它们到达的间隔与到震源或初始破裂点的距离成比例地增加。
Because P and S waves travel at different but fairly constant speeds, the interval between their arrivals increases in proportion to the distance from the earthquake focus, or initial rupture point.
由于初始化时间直接与对象的大小成比例，因此时间是线性的，而不是常量。
Since the initialisation time is directly proportional to the size of the object the time is linear rather than constant.
