Non-divergence form operators and variations on Yau's explosion criterion

To avoid the problem of schemes combination explosion caused by unbounded depth in the search process, bounded depth-first search was used to control the number of expanded hierarchies for a design tree.

The Meishucun stage is the prelude in deciphering the Cambrian Explosion.

These new materials provide new evidence for the origin, evolution and the functional evolution of the metazoan during the early stage of the Cambrian Explosion.

Numerical analysis of welded joint treated by explosion shock waves

An evaluation formula of the detonation wave pressure in the system of laser, energy transferring-medium and sheet metal is built according to the theory of detonation wave and blasting gas-dynamics.

multicycle pulse detonation engine (PDE) model, and liquid fuel (gasoline) was used.

The average of pressure peak, as measured by piezoelectricity pressure transducer, increased versus distance to thrust wall before fully-developed detonation came into being.

According to the pressure history, the pressure in detonation tube would not rise abruptly until the flame front advanced a certain distance downstream the spark.

One was enforced by combustion and became detonation rapidly.

The explosive performances of DAAT were calculated theoretically by VLW equation-of-state (EOS) and the results showed that several explosive formulations based on DAAT have high-energy and insensitive performance.

Secondly, the effect of explosion shock waves, produced by plastic strip-like explosive, on welding residual stress distribution was predicted with coupled Lagrange-ALE algorithm.

Transformation characteristics of TiNi/TiNi alloys synthesized by explosive welding

The black shales also contain K-bentonites from explosive, felsic-intermediate volcanism, the distribution of which also supports orogeny to the southeast.

The model of a current meander is put forward, which explains the generation of an inductance electric field, current wedge, and other effects of the explosive onset of a substorm.

Such dwarfs probably explode as type-Ia supernovae or collapse to form a neutron star.

If they explode, the Earth will be subjected to concentrated bombardment by cometary nuclei, which will create a "nuclear winter" once every 60 years on the average.

Induced explode-decay dromions in the (2?+?1) dimensional

In this study, we used a batch reactor to steam explode corn fiber at various degrees of severity to evaluate the potential of using this feedstock in the bioconversion process.

A batch reactor was employed to steam explode corn fiber at various degrees of severity to evaluate the potential of using this feedstock as part of an enzymatically mediated cellulose-to-ethanol process.

In the nuclear stratigic anti-attack of the war, We must to give the probability distribution of the demaged numbers of the single target in the target system, in order to improve the killing effectiveness. In the past, one considered the all different conditions which may occur in the anti-attack when nuclear weapons is thrusted. Then, using the method of combination to give the probability distribution of the numbers for the demaged targets. This method is trubsome, especially when the numbers of the target...

In the nuclear stratigic anti-attack of the war, We must to give the probability distribution of the demaged numbers of the single target in the target system, in order to improve the killing effectiveness. In the past, one considered the all different conditions which may occur in the anti-attack when nuclear weapons is thrusted. Then, using the method of combination to give the probability distribution of the numbers for the demaged targets. This method is trubsome, especially when the numbers of the target is large. For this reason, We introduce the idea of target state, then apply ChapmanKolmogorof eguation to calculate the transition probability of the state for the target system. We obtain the recursive algorithm, and the calculation is much simpler. In the end of this paper we consider the mathematical models of the target allocation problems. Usually, we may discuss these problems by means of programming method.

A variable reluctance pressure transducer is described in this report.It has been successfully used for close-in shock waves measurements of nuclear explosion in the atmosphere.The highest pressure range of this transducer is 100kg/cm2 and the response rise-time to all ranges is about 1 ms.It is equi-ped with a special pressure lead tube filled up with oil,the construction of which makes it possible to be installed underground,therefore it can withstand the intense nuclear radiation without losing its quick-response...

This paper describes some of the experimental results (overpressure, impulse ,duration) of an underwater explosion near the water surface. For an underwater explosion hear the water surface, the shock wave in water will change evidently. Experiment shows that there are two kinds of reflections of the free surface, one of them is linear reflection called "the surface cutoff" and is clear to us.The other is nonlinear reflection ,the shock wave is much distroyed and its peak overpressure is much decreased. In this...

This paper describes some of the experimental results (overpressure, impulse ,duration) of an underwater explosion near the water surface. For an underwater explosion hear the water surface, the shock wave in water will change evidently. Experiment shows that there are two kinds of reflections of the free surface, one of them is linear reflection called "the surface cutoff" and is clear to us.The other is nonlinear reflection ,the shock wave is much distroyed and its peak overpressure is much decreased. In this peper the later is comprehensively discussed . Through a great deal of test and analysis, a mathematical model of the overpressure is formulated . The formula is obtained from the Cole formula with revised cofficient and power. The coefficient is revised by the idea of energy released from free surface into atmosphere .
