With NA-22/TT/Pb3O4/MgO as the vu lcanizate system of ECO,DCP/TAIC/TT/MgO as the vulcanizate system of NBR,and fil led with 1.5 phr TT,the resulted covulcanizate rubbers of ECO/NBR demonstrated t he optimal balance among mechanical properties,air aging properties and oil resi stance.

Results ①When the detection pinhole was set to 1 Airy Disc, an optical section with the optimal balance between the resolution and the signal loss could obtained by fulfilling the condition that the fluorescence intensity in the focus plane falls to 50% maximum when the scanning plane leaves a distance of 1/2 Z-direction resolution (=2λ/NA2) from the focus.

Ecological forestry is a kind of development mode of modern forestry that conforms to the ideas of sustainable development,whose core is pursuing the optimal balance of ecological economy.

In the practice of intellectual property protection, we should do our best to find the optimal balance between these conflictive interests and to harmonize them so that the development in science and culture can be promoted as well as the justice domestic and international can be maintained.

This paper deals with the theory and practice of the thrus-tless dual connecting rod ICE, including: analysis of schemes, analysis of kine-matics, dynamicsand optimal balance.

It is necessary to take all factors into consideration and well handle the balance between different aspects of the contradictions,so as to reach a new optimal balance in general values of building a new socialist countryside on the west side of the Straits between aspects within the contradiction and among these contradictions,thus to add new motive force to building a new socialist countryside and expand a broader space for it.

The concrete topics as following. Data storage, the author improved the storage model of stage-change data to make an optimal balance between the space and performance.

This work presented a new framework for forecasting and procuring automatic generation control (AGC) capacity in order to achieve optimal balance between economic efficiency and system security in the competitive electricity market environment.

Simulation results have shown that TWFS can made an optimal balance among effectiveness、fairness, and complexity and is most suitable for future high-speed EPFTS nodes in SUPANET.

DACA can make an optimal balance between the affinity-based routing and indiscriminate sharing of load in the SD cluster.

This study shows how to put parallelism to best use, that is, how to find an optimal balance between communication and computation overheads for two parallel matrix algorithms.

From the evidence available, it is suggested that a three-frame unit of agreement might be the optimal balance between reliability magnitude and significance.

The analysis results in a semantic rule, expressing the meaning of quality as an optimal balance between possibilities realised and a framework of norms and values.

The paper extends the concept of regulatory threat to vertically related markets, stressing an optimal balance between the level of the network access charges and discrimination against third parties.

To calculate a static balance,the force due to inertia acting on the parallel double crank mechanism is transformed into static equivalent generalized mass.There exists, however,unbalanced inertial couple moment on the bearings.The investigation conducted by the authors into such a case leads to their proposal of a set of more appropriate formulae as follows: (?) when these formulae are applied to the calculation concerning the static balance in the parallel double crank mechanism,an optimal balance state...

The impulsive tensile corrosion fatigue of a low alloy high. strength steel 23MnCrNiMo64 quenched and tempered at low and middle temperatures was studied in weak acid and weak alkali mediums. The fracture features and characteristics of broken specimens were examined by means of a scanning electronic microscope. The qualitative analysis of the corrosion products was made by means of a Auger spectrograph. The objectives of this investigation were to find out the optimal balance between stength and toughness...

The impulsive tensile corrosion fatigue of a low alloy high. strength steel 23MnCrNiMo64 quenched and tempered at low and middle temperatures was studied in weak acid and weak alkali mediums. The fracture features and characteristics of broken specimens were examined by means of a scanning electronic microscope. The qualitative analysis of the corrosion products was made by means of a Auger spectrograph. The objectives of this investigation were to find out the optimal balance between stength and toughness against corrosion fatigue to anticipate the properties of a material, and to provide some guidance in the rational choice of heat treatment regime. The possibility of cold rolling to enhance the resistance of a material to cerrcosion fatigue is also discussed in this paper.

This paper deals with the theory and practice of the thrus-tless dual connecting rod ICE, including: analysis of schemes, analysis of kine-matics, dynamicsand optimal balance. The advantages of the dual connectingrod ICE are proved by both practice and theory.
