The basic idea is as follows: first, a kind of plane α-B-spline interpolation curve with a shape control parameter a is constructed; then, by converting the first derivatives of the curve into Bernstein polynomial, the positive conditions of Bernstein polynomial can be used to get the necessary and sufficie nt conditions for the monotonicity of α-B-spline interpolation curves, i.e., the range of the parameter a. Therefore, monotone-preserving interpolating curves can be obtained succinctly.

综合分析认为震动塌落、震动拉伸变形、地震断裂面的摩擦作用、氧化还原反应和扩散作用是环状层理的主要成因，前三种成因的环状层理往往与其他震成构造伴生，可作为震积岩的良好标志。环状层理的其他成因还包括：地震波传播方式的影响、地球自转产生的涡旋的影响、"滚雪球"效应、间歇胶结作用以及生物成因等。

Firstly, a mathematic model was constructed to deal with fault isolation. This model mainly considered the associations among fault sources and available testing of hierarchical system, the affiliation of faults with replaceable units in different levels, the prior probability of fault sources and the available testing costs. Secondly, a quasi multi-step look-ahead search algorithm was presented which employed the information gain as its heuristics. This algorithm could realize optimization of testing sequence in different isolation levels.
