The drilling speed may be effectively raised through applying the combination drill coordinating with PDC or strong gauge and high rotary speed cone and the large diameter drill pipe and collar,etc.
Results The CD44 v6 positive staining were not detected in nomal gallbladder tissue,the positive rates in gallbladder carcinoma and adenoma were 62.1% and 19%,respectively. The expression of CD44 v6 was related to tumor lymph node metastasis (P<0.05). The positive rates of CD44 v6 were significantly higher in cases of poorly or undifferentiation than that of well differention(P<0.05).
In this paper, the mistake in literature [7] is illustrated by a counter example, and when χ~2 ordering method is applied to the reciprocal judgment matrix, a study is conducted to the conditions of strong order-preservation and weak order-preservation for adding new elements into reciprocal judgment matrix.
Another strong gauge of the quality of a book is its relevance and applicability to practical problem-solving.

This paper analysed the water physioloyical characteris-tics of 5 species of rare plants. The purpose is to find out the appro-aehes of the plant adaptablities to the drought environment.The result shows that Ammopiptanthus nanus has a strong waterholding power and water-absorbing capacity. It can adapt itself to the drought environ-ment well. Ammodendron loifoliuan has a high transpiration rate and Strong water-absorbing capacity. Cymncarpos przewalskii adapts itslf to the environment by a strong water-ho...
The physiological characteristics of drought tolerance of tree specics which possessdifferent mechanisms of drought tolerance were studied with respect to leaf water-holdingability and maintenance of turgor in this paper. The results show that the tree species whichbelong to drought tolerance with dehydration postponment at high tissue water potentialhave the strong abilities to hold water and maintain turgor, which are one of the most impor-tant characteristics of drought tolerance. But the species which b...
In this paper,the relation between the reverse order and its decision making environment in AHP is studied.The decision making environment and phenomenon of reverse order are defined. The mechanism of causing reverse order is analysed mathematically and explained qualitatively. A strong keeping order thoorem under multi-criterion is given. Finally,the direction of further researches is pointout.
