Using simulations, we found the best geometry of the collimator is the one with a rectangle aperture and all of them are placed in two groups with an orthogonal orientation, which will have good resolution and sensitivity, and also be easy to manufacture. The rectangle aperture gives good imaging accuracy along the short side, and wide viewing along the long side. The orthogonal orientation for collimators will allow us to observe the source and the background simultaneously.

通过模拟发现，综合考虑了对强源成像的分辨率以及对弱源的灵敏度，以及加工的容易程度，论文提出了最优的准直器设计方案是用长方形准直器，并且将所有准直器分成两组，垂直摆放，一方面可以约束两个方向上的成像质量，同时具有较高的成像分辨率和定位精度，并且非常利于定点观测时的源和本底同时观测。

In the second part, by using uniform design and orthogonal design methods, some groups of mix test of foam lightweight with different component are conducted, the test data is analyzed by neural networks model and regression model, and optimum mix proportion is obtained. Orthogonal design for mix material considering density factor is presented, as well as uniform design for mix material adapting to different density. The mechanic characteristics of foam lightweight material and engineering characteristics differing from general material under an allround press are founded. Through the analysis of asymmetry settlement for Doulong sluice and the comparison of correct deflection scheme, the foam lightweight material shows some advantages in the load reduction.
