An informed understanding and appreciation of blood related crime scenes is only achieved through practical experimentation of simulated blood spatter. Because of the increasing frequency of the HIV, Hepatitis B and C viruses, the use of human blood may be hazardous for those involved in such experimentation. Porcine (pig) blood has been cited by some as a reasonable alternative, and this paper presents a comparison of the physical parameters (surface tension, viscosity and density) of ageing pig and fresh human blood, under a variety of conditions, as well as measurements of droplet trajectories and stain patterns. The results support the use of porcine blood (up to two weeks old) in representing the behaviour of freshly spilt human blood.
只有通过模拟血液飞溅的实际实验，才能对与血液相关的犯罪现场有深入的理解和认识。由于艾滋病毒、乙型肝炎病毒和丙型肝炎病毒的感染频率不断增加，使用人类血液进行此类实验可能对参与者构成危险。一些人认为猪血是一种合理的替代品，本文比较了不同条件下老化猪血和新鲜人血的物理参数（表面张力、粘度和密度），并测量了液滴轨迹和血迹模式。结果支持使用（保存期长达两周的）猪血来模拟新鲜溅出的人血的行为。
