查询词典 preference testing

The third part is to analyze the gender preference of peasants in village N, S and village B based on the data of fieldworks and SPSS. It is found that, without taking the birth control into consideration, son preference ratio of peasants in village N, S is 24% higher than that of village B. Suppose that only one child is allowed in one family, son preference ratio of peasants in village N, S is about 40% higher than that of village B.

研究发现，在不考虑胎次的情况下N、S两村农民的偏男系数比B村高24%，在假设只能生育一孩的情况下，N、S两村农民的偏男系数比B村高出将近40%；在生育行为方面，N、S两村农民明显偏好男孩，B村农民没有性别偏好；在孩子的抚育方面，N、S两村农民与B村农民没有显著性差异，均没有偏好男孩的表现。

In order to facilely perform testing on C or C++ programs, a prototype tool called CppTest is designed and implemented. It can employ three levels'testing, namely (1) structural testing in method level by analyzing program's constructs, instrumenting probes, redirecting I/O stream, etc.,(2) state-based class level testing through modeling state transition behaviors using an extended finite state machine from the class specifications, and (3) system level black-box testing with some traditional strategies such as equivalence partitioning and boundary-value analysis.
