Critical direct line relation between time interval τ and space distant d of adjacent is d∞ τ(-1.0), relation between migrate rate v and τ is v∞ τ(-2.0).

The direct line mutant of Spirulina platensis (SP-Dz) was studied by the comparation of the growth characteristic and the content ofphycobiliprotein under the condition ofdifferent pH values and the result indicated that the optimumpH range for SP-Dzgrowth was between 9.0and 10.5 and the optimumpH for phycobiliprotein accumulation was pH 9.5.

APC of electrophoresis-purity was obtained from Spirulina using ammonium sulfate grade precipitation followed with several gel chromatography, and the purity (A_ 650 /A_ 280 ) of which attained to 4.83. The fluorescence scan curve of APC was a direct line in 30 min;

Polygon simplification in scaleless GIS (geographic information system) is based on the line generalization of polygon arcs, but there may be topological errors in output data resulting from the direct line generalization of polygon's arcs, and the major representation of the error is the intersection of the simplified polygon's arcs.

无级比例尺 GIS(geographic information system)多边形化简的基础是多边形弧段的线综合 ,而直接对多边形的弧段施加线综合操作可能造成输出数据的拓扑错误 ,主要表现为化简后弧段出现相交 .

An important property of the environmentof such systems is the interference caused by scattering of the signal froma subscriber transmitter into directions other than the direct line of sightbetween the subscriber and the base station.

The radiative temperatures obtained with allowance for the spectral dependence of the emissivity of a mixture of the above-mentioned gases calculated by the direct line-by-line method are taken as the input data.

To reduce the radiation damage in the superconducting, focusing magnets, tapering the beam ports along the direct line-of-sight component of the source neutron is necessary in the magnet regions and also in the collimator region.

These two approaches provide the means to assess the patterns and evolution of horizontal flows on supergranular scales even near disk center, which is not feasible with direct line-of-sight Doppler measurements.

By aid of Eshelby's theoretical development, and through the use of a direct line integration procedure for the evaluation of the required path-independent integrals.

In this paper, the result of reservoir simulation in calculating the areal sweep efficiency is given for some well patterns, such as five-spot, seven-spot, direct line drive and staggered line drive. A full picture of water displacement is systematically evaluated and demonstrated in a series of figures that give the areal sweep efficiency for each well pattern in relation to mobility ratio, dimensionless water injection volume or water fraction of proportion. It has been proved that the value of...

In this paper, the result of reservoir simulation in calculating the areal sweep efficiency is given for some well patterns, such as five-spot, seven-spot, direct line drive and staggered line drive. A full picture of water displacement is systematically evaluated and demonstrated in a series of figures that give the areal sweep efficiency for each well pattern in relation to mobility ratio, dimensionless water injection volume or water fraction of proportion. It has been proved that the value of Ea determined by simulator is more close to the real value in reservoir than thatdetermined by other methods. The result can be used to determine the production performance of oil reservoir with corresponding flooding pattern.

It is known from works of S.Shelah and P.Eklof that the Whitehead problems for abelian groups as well as for many modules are independent of ZFC.However, Eklof has established the latter results mainly by homological arguments.The author remarks that, for principal ideal domains R, the independency of Whitehead problem for R-modules can also be established along a more direct lines.The main parts of the proof are analogous to that given, while some modifications are needed in the construction of an uncoulntable...

In this paper,time-space immunity which occured next one after an earthquake occured was detailed studied. The results show that characteristics of immunity of Qinghai earthquakes is remarkable. It has significant to further understsnding seismic time-space teature.Critical direct line relation between time interval τ and space distant d of adjacent is d∞ τ(-1.0), relation between migrate rate v and τ is v∞ τ(-2.0). the fractal dimension value 1.0 is correspond to zipf law, It is similar to 1/f spectrum....
