While the computer visualization has been used in various research fields, there is no practical application to the analysis of insect behaviour. In addition, some interests have been taken in what conditions disturb the normal spinning process of a silkworm or in how the silkworm behaves under abnormal conditions. We, therefore, investigated the silkworm's repairing behavior when a small part of the cocoon being spun was cut. Then, after some statistical models were constructed to represent the silkworm's behavioural pattern, a simulation method was devised using the results. Furthermore, we tried to develop a new computer visualization system for the research of silkworm's behaviour. The results are as follows ; 1. Analysing the fixing and moving of a silkworm body during spinning process, we showed that the periods of time approximately follow the mixture Gamma distribution for the moving and lognormal distribution for the fixing. 2. The relationship between the period of moving time and the moved angle of a silkworm body was represented by an equation. 3. A new simulation algorithm was devised for the spinning behavior of a silkworm. 4. A 3D visualization system for silkworm's behavior was developed using a Windows personal computer.

虽然计算机可视化已经在各个研究领域得到了应用，但在昆虫行为分析方面还没有实际应用。此外，人们还对什么条件干扰了家蚕的正常吐丝过程或家蚕在异常条件下的行为也产生了一些兴趣。因此，我们研究了当蚕茧的一小部分被切断时，家蚕的修复行为。然后，在构建了一些统计模型来描述家蚕的行为模式之后，利用这些结果设计了一种模拟方法。此外，我们还试图开发一种新的计算机可视化系统来研究家蚕的行为。研究结果如下：1.分析了蚕体在纺丝过程中的运动和运动过程，发现运动的时间周期近似服从混合伽玛分布，而运动的时间周期服从对数正态分布。2.蚕体运动周期与蚕体运动角度之间的关系可用方程表示。3.设计了一种新的家蚕吐丝行为仿真算法。4.在Windows个人计算机上开发了家蚕行为三维可视化系统。
