INTRODUCTIONDuring the last two decades the kraft process hasbeen extensively modified resulting in significantimprovement in uniformity of pulp quality andprocess selectivity. The principles of extendeddelignification for modern pulp mill was developedduring the 70's and have been refined and applied incommercial practices, although the nature of kraftpulping kinetics are not yet fully understood due tothe complex heterogeneity of the process. Modern kraft pulping methods involve splitt… 相似文献

An analysis is proposed for Laser Doppler Anemometers (LDA) by using the principle of optical-beating and the concept of conditional and unconditional heterodyne contribution is introduced. An experimental set-up of LDA withvinterference plane gradients is constructed to separate and enhance the conditional heterodyne contribution. 相似文献

The special formulation that allows an accurate and efficient solution to the heat transfer problems within fin assemblies with very large aspect ratios has been developed in this paper Numerically, it consists of the boundary element method in the wall region and the analytical solution in the fin region This modified BEM makes tractable a large class of heat transfer problems in the long and thin domains which are frequently encountered in practice. 相似文献

A good novel depends on the success in portraying the characters in it. In Tess of the D'Urbervilles, Tess is a beautiful country glrl. In this novel, she is a new woman. She is not submissive to man and full of rebel spirit. Because she is educated, she has a strong self-respect. The more important is that after being seduced, she not only maintains her virtue but also becomes stronger. Her true and pure love for Clare drives her to break the convention and tolerate others' satire. 相似文献
