This paper expounds the necessity of the agricultural sci-tech innovation,analyzes on some problems existing in Chinese agricultural sci-tech development,and probes into how to construct the new countryside with the agricultural sci-tech innovation.
The government should formulate plan for the development of agricultural recycling economy,carry forward the establishment of technological innovation system and construct demonstration project to create a sound institutional environment for the development of agricultural recycling economy.
This Peper analyzes the mechanism proceeding of developments of pushing forward from the theories, and gives some suggestions to improve the village information by creative cooperation of the economy's organizes.
In the case of 4-dimensional anticommutative algebras a construction is given that links the associated cubic surface and the 27 lines on it with the structure of subalgebras of the algebra.
The aim of this paper is to discuss a construction of a class of linear isomorphisms σ:S(g)→U(g) which commute with the adjoint representation.
However, there are many examples that do not arise from this construction.
Using the properties ofn-Hopf algebras we show that certain spaces do not admit the structure of ann-valued group and that certain commutativen-valued groups do not arise by applying then-coset construction to any commutative group.
We give complete proofs of the K-theoretic construction of the quantized enveloping algebra of affine gl(n) sketched in [GV].
Recent developments of the ultra-wideband (UWB) planar antennas are reviewed, where the progress in UWB plate monopole antennas, UWB printed monopole antennas and the UWB printed slot antennas is introduced and compared.
Besides the needs arising from large-scale high-temperature plants, the high tech developments, such as micro chemo-mechanical systems and high-power electronics, provide new challenges to structural integrity technology.
We review the developments of the multipole expansion approach in quantum chromodynamics and its applications to hadronic transitions and some radiative decays of heavy quarkonia.
Characteristics and developments of quantum-dot infrared photodetectors
From the limited but available information, we traced the history of developments of liver surgery and transplantation in China.
