It is also convenient for data conversion in different CAD systems by using elevation algorithm.

The test theory,design procedure and data analysis of Langlie method and up-and-down method were analyzed,and the experimental results of impact sensitivity of certain explosive HMX were compared.

Critical initiation energy was measured by the up-and-down method and cell size on soot foil.

By comparing the advantage and disadvantage of ramp current with other methods,ramp current method and up-and-down method are used to test sensitivity of bridge-wire Electrical Initiating Device.

Since Dixon and Mood gave the up and down method for small samples,the up and down method has been widely used to determine statistical characteristics of material′s fatigue strength.

Experiments show that the fatigue limit evaluated according to this expression is approximate to the result deduced from up and down method,which demonstrates that in describing the fatigue property of metal,the expression enjoys higher accuracy and certain practical value.

Mood and developed by some other experts,but all these traditional up and down methods can not use previous data effectively, besides, the estimates for variance are not exact.

Using the sensitivity test data of the stab detonator compares the complete run-down method and Bruceton up-and-down method.
