In two experiments the results demonstrated: The gonadotropin may increase the libido of buck, sperm concentration (P< 0. 05), motility rate(P<0. 05) and living sperm number per ejaculation(P<0. 01) siffnificantly.
10 heat street buck were treatment by testiculin (T), humun chorionic gonadotrophin (HCG), luteinizing hormone (LH) , and pregnant mare serum gonadotrophin (PMSG) ; and 10 buck were control group. Result of the test, 1 group, musculature injection T every day 5 mg, continous for one week, at the same time of treat 1,3,7 day injection HCG 20 IU, 5 day PMSG 20IU respectively;
This paper investigates Buck's question about which class of spaces is strongly monotonically T2, and if other properties are combined with strongly monotonically T2, which class of spaces could be got.
The soil buck density of 0-10 cm were slightly higher under canopy than that in gaps, but there was no significant difference in the soil buck density of the 10-20 cm soil layer.
The power stage of the source is connected as a buck regulator operating at a frequency of 50 kHz with an efficiency of ≥85%.
Modification of Pantle-Buck Technique for Assessing Watercourse Pollution Based on Macrobenthos Quality Characteristics
The index is similar to the Pantle-Buck saprobity index, but is based on qualitative characteristics and uses macrobenthos families (rarely genera), for which original values of saprobity and indicator weight are given.
