success ratio
8.We have made the bold improvement in view of the student characteristic to the teaching material, supplemented these two aspect content, the effect obviously has been also good, in Ban Yuban contrasted Ban Gao who the content supplemented the class which to manufacture the success ratio which compares obviously does not supplement.
9.The function and operating technology of cement squeeze in Caracoles oil field administrated by CNPC America Ltd. Venezuela and an actual example of plugging perforations by cement squeeze in the oil field are introduced in the paper. A total of 125 well time cement squeeze works had been carried out from 1998 to 2001 in the oil field with a success ratio of 100%.
10.Traffic simulation is used to analyse the performence of two kinds of dynamic routing schemes which are called Dynamically Controlled Routing (DCR) and Dynamic Alternate Routing(DAR). The running case of our toll network adopting dynamic routing strategy is studied, the improvement of call success ratio and adaptive ability to network failure is evaluated, and the parameter of trunk reservation in DAR is selected based on experiments.
