and the adhesion of belt increased,the endurance and speed performance of finished tire improved by using 4+6×0.38HT Betru steel cord in the second and third belts of 11.00R20 18PR TBR tire instead of 3+9+15×0.22+0.15 steel cord.
The results showed that the strength of finished tire was unchanged,the endurance and speed performance improved,and the tire weight and production cost reduced by using 0.365+6×0.35HT Betru~ steel cord instead of 3+9+15×0.22+0.15 steel cord in the belt of 10.00R20 16PR tire.
The test results showed that when 3×0.20+6×0.35HT steel cord was used in the belt of(10.00)R20 TBR tire instead of 3+9+15×0.22+0.15 steel cord,the safty factor reached the aim of the design,the good processibility was obtained,the strength,endurance and speed performance of finished tire met the requirements in service,and in addition,the tire weight and cost reduced.
The activities of POD, SOD and CAT increased first but decreased then with the increasing Cu concentration, and the endurance index of root showed the same trend, being >0.5 at the Cu concentration less than 20 mg·L~ -1 while decreased to 0.36 at 40 mg Cu·L~ -1 .
Under weak light(60~80 μmolm~(-2)·s~(-1)),sub-low temperature and weak light co-operation(20℃/12℃),the growth of leaf area was all consistent with the(endurance) to weak light and low temperature among all the cucumber strains.
弱光(60~80μm o lm-2.-s 1)、偏低温(20℃/12℃)弱光胁迫下不同黄瓜的叶面积增长量与其已知的低温弱光耐性一致。
And two cultivars, one tenderness to root-zone hypoxia stress, one endurance , were adopted to research their ROS mechanism and the changes of antioxidant activity under hypoxia , in order to discover the physiological basis of different hypoxia tolerance.
The stated results proved that the concentrated PHKCV had better immune endurance and the immunememory could maintain two years induced by ID 0.1mL nonconcentrated PHKCV. The immune effect inoculatedby IM two to three doses on day 730 after ID 0.1mL nonconcentrated PHKCV was better than that of five routine doses as the first time vaccination.
The efficiency of ME embodies mainly the degree of ME realizing the purpose, the depth and endurance of effect on students’moral character such as thought, politics, ethics and legality, and the effect on students’discrimination, selection and understanding.
It is shown that the rigidity and heat endurance of cryogels rise with an increase in the concentration of initial PVA solution and a decrease in the rate of thawing.
Based on this information, the integral self-rating of the intensity of the physical load and its endurance is formed in the sensory CNS sphere, with one of the signals to stop the work being the feeling of shortness of breath.
The relationship between the rheological blood properties and several indices of age-related erythrocyte structure was established in endurance-training athletes (n = 21).
Erythrocyte aggregation (examined microscopically in diluted blood), lipid and protein plasma profiles, and fibrinolytic activity were studied in endurance athletes.
The main bioenergetic qualities-the alactic anaerobic, glycolytic anaerobic, and aerobic potentials-are the main factors of endurance in athletes.
