重复试验

In the research of high cycle fatigue of concrete, the test means of cyclic loading between the set constant or various upper limit and low limit of force or stress has been extensively used. But this kind of test means can't be used to study the behavior of concrete low cycle fatigue under large strain.

同时高周疲劳问题研究中使用的在设定的力或应力的上下界限之间重复受力的试验方法已无法用于混凝土高应变低周疲劳性能的试验研究。

It was found that the low cycle fatigue character has close internal relations with the high cycle fatigue character. In the research of high cycle fatigue of concrete, the test means of cyclic loading between the set constant of force or stress has been extensively used. But this kind of test means can't be used in studying the behavior of concrete low cycle fatigue under large strain.

在研究中发现低周疲劳特征与高周疲劳特征有着密切的内在联系，但高周疲劳问题研究中使用的是在设定的力或应力的上下界限之间重复受力的试验方法，这种方法已无法用于混凝土高应变低周疲劳性能的试验研究。

To explore the different high north of chili peppers mode, the influence of main pests with pepper and corn were mainly by intercropping with corn, chili, peanut, sunflower not counterparts, than intercropping set 10 processing, 3 replicates, randomized to design, in May 2008 in October - high north county village dragon tree bark planting experiments on biodiversity village.
