Studies on specific property of population growth of Moina rectirostris, Simocephalus vetuloides, Daphnia pulex forma schoedleri Stars were conducted under 28± 0.5℃ .
在28±0．5℃控温条件下,对直额裸腹溞(Moina rectirostris)、拟老年低额溞 (Simocephalus vetuloides)、细长型蚤状溞(Daphnia pulex forma schoedleri Stars)进行了种群增长特性的研究。
The growth of Artemia sp. is fast with increasing of the salinity at a certain temperature. At 20℃ the nauplius average length is 861.9μm under 20‰ salinity and decreases to 644.5μm under 2.5‰ salinity.
The research indicated that the feed with additive of photosynthetic bacteria(PSB) could improve the growth of grass carps and reduce the feed conversion rate significantly,after 42 days the relative growth rate was increased by 61.7%.
In the period of 27 to 29 days, the organ differerntiation have finished, the odd and even fins are formed with an average body length of 27.79 mm during juvenile, After the scales of the young are fully developed, it enters into a period of rapid growth.
Complexity of Homogeneous Spaces and Growth of Multiplicities
We give a representation-theoretic interpretation of this number as the exponent of growth for multiplicities of simple G-modules in the spaces of sections of homogeneous line bundles on G/H.
A necessary and sufficient geometric condition on the growth of the boundary of approximate tiles is reduced to a problem in Fourier analysis that is shown to have an elegant simple solution in dimension one.
We prove a Tauberian theorem of the form $\phi * g (x)\sim p(x)w(x)$ as $x \to \infty,$ where p(x) is a bounded periodic function and w(x) is a weighted function of power growth.
A complex Radon measure μ on ?n is said to be of at most exponential-quadratic growth if there exist positive constants C and α such that.
