1 Results All patients have gained a satisfactory operative effciency.

2 The authors discuss asymptotic effciency of MLE in asymptotic median unbiased sense under regular conditions.

3 Mode strain energy is used in the damaged structures; and an experiment is carried out to verify its effciency.

4 Adopting a strength testing system of high accuracy and effciency.

5 We believe in doing the work for all our customers in-house, which will guarantee effciency and service to customers at competitive charges.

6 These steps above had made furnace heat - exchanger performing high effciency, prolonged its life - and reduced consumption.

7 The result shows that this process has shorter fermentation time and higher effciency. lf the plum vinegar mixed with other ingredents, a series of healthy vinegar drinking can be produced.
