The result shows that cooked with 8-10/100 of the abovemixed starch(in proportion as 5 :3),adding 1/100 agar powder and 2-4/100 sucrose, the″cm-pound starch gel″can be perfectly sliced and stained for many enzymes,such as PGM,PGI, MDH,AAT,SKDH,6PGD,IDH,ME etc. for varied kinds of plant materials.

The serious lag of college English writing instruction in the whole English teaching is a common phenomenon,yet it is very difficult for many colleges to establish writing courses in the near future.

As to many organizations, business process re-engineering (BPR for short) is one of the ways of realizing their potentiality of competition, it has one objective (outstanding performance improvement), one focus (process) and one requirement (promise of the managerial personnel).

对许多组织来说，业务流程再造(Business Process Re-engineering，简称“BPR”)是实现他们竞争潜力的途径之一，它有一个目标(显著的绩效改善)、一个焦点(流程)和一项要求(管理者的承诺)。

On the other hand,the TAS-Pt ahd MDAS-Pt curing systems shows excellent adhesive property to many kinds of materials especially metals and still retain their adhesiveness after immersion of the samples into water for 15 days.

Several independent population studies have reported that the apolipoprotein C3 (APOC3) SstⅠ polymorphism in apolipoprotein (apo) A1/C3/A4/A5 gene cluster is associated with Hypertriglyceridaemia (HTG). HTG is a known risk factor for coronary atherosclerotic heart disease(CHD)and type Ⅱdiabetes mellitus(non-insulin-dependent diabetes,NIDDM).

Experimental effect of chemical weed in nursery of Chinese fir showes: it iseffective for weeding with trifluralin of 1.8 litre and water of 900 kg per hectare to sprayseedbed in 10～15 days before budding,weeding rate is above 85%, effectiye period of herbicideis long and nursery stock is safe.

A new gas chromatographic stationary phase called perpentyl(2,3,6_tri_(O_2′_hydroxy_ propyl)_β_CD has been synthesized based onβ_CD.The chromatographic property of the stationary phase was studied through the retention behavior and the separation of a series of compounds.It was found that the isomers,especially the enantiomers were well separated.

Therefore, our results give in particular a unified construction for many moduli spaces considered in the literature.

Then it is shown that for many (and perhaps all) pairs E, F, of wavelet sets, the corresponding MSF wavelets can be connected by a continuous path in L2(?) of MSF wavelets for which the Fourier transform has support contained in E ∪ F.

HIV is the most significant risk factor for many opportunistic infections like tuberculosis, hepatitis, bacterial infections etc.

Lycium barbarum, a famous Chinese medicinal herb, has a long history of use as a traditional remedy for many diseases.

By comparing the calculated and measured data of the boresight error and the boresight error slope before and after grinding, it is shown that this method is simple and practical and can be used for many kinds of radomes.

This new method can be applied to many other problems, where wavelet bases are not available.

The ideal properties of DDBHMM give promise to many aspects of speech modeling, such as the modeling of the state duration, speed variation, speech discontinuity, and interframe correlation.

The syntonic frequency of the MOS RO changes in relation to many environmental elements, such as temperature, source voltage, and so on.

Though this algorithm has been applied to many fields, the analysis about its convergence is much less, which will influence the improvement of this algorithm.

Our predictions fit to data and to many other different calculations quite well.

The much discussed and controversial problem1) of ultrasonic absorption in ethyl and methyl acetates has been further investigated experimentally by the method of optical diffraction2) in progressive ultrasonic waves. In designing the equipment and throughout the measurement, special cares have been taken for the plane progressive nature of the ultrasonic field in the liquid trough, the elimination of stray light effect so that the receiver (a photomultiplier with preamplifier and a frequency analyzer connected...

The much discussed and controversial problem1) of ultrasonic absorption in ethyl and methyl acetates has been further investigated experimentally by the method of optical diffraction2) in progressive ultrasonic waves. In designing the equipment and throughout the measurement, special cares have been taken for the plane progressive nature of the ultrasonic field in the liquid trough, the elimination of stray light effect so that the receiver (a photomultiplier with preamplifier and a frequency analyzer connected in series) could respond with precision the relative light intensity of the first diffracted maxima at different stations along the ultrasonic beam, etc. Automatic recordings of sound absorption coefficients were made possible by the sound level recorder synchronized with the motion of the liquid trough. Several standard liquids have been tested; the absorption coefficients thus obtained agree well with commonly accepted values.

In this work, it has been found for an ellipsoid of a ferrimagnetic with two equivalent sublattices of unlike ions that the frequency spectrum of spin waves consists of two branches and in each of them the dependence of frequency on the wave vector is similar to the spin wave spectrum of a ferromagnetic ellipsoid. Based on this spectrum and the scattering mechanism of spin waves due to the fluctuation of exchange interactions, calculations have been made for the line width of the uniform resonance and that of...

In this work, it has been found for an ellipsoid of a ferrimagnetic with two equivalent sublattices of unlike ions that the frequency spectrum of spin waves consists of two branches and in each of them the dependence of frequency on the wave vector is similar to the spin wave spectrum of a ferromagnetic ellipsoid. Based on this spectrum and the scattering mechanism of spin waves due to the fluctuation of exchange interactions, calculations have been made for the line width of the uniform resonance and that of the exchange resonance. For the former the conclusions obtained by using the model of an equivalent ferromagnetic are still valid; i.e. nonmagnetic impurity ions and the impurity ions whose spins equal to that of the matrix ion on the same sublattice have no effect on the line width of uniform resonance. However, the impurity ions of both these kinds should give rise to the line width of exchange resonance. There exists a large difference in the line width of uniform resonance estimated for various ferrites by making use of our simplified model of ferrimagnetism. Quite probably the fluctuation of the exchange interactions is the main cause of the line width of uniform resonance in a number of ferrites. The exchange resonance line width caused by this mechanism are estimated for ferrites generally of the order of several tens in the oersted.
