There are two kinds of spinels in a granulite terrain of Yushujgou, South Tianshan Mountain. One occurs in the intermediate and basic granulite units and is characterized by enriched Al and poor Cr, belonging to Al_spinel. In thin sections it shows dark green color and subhedral to anhedral form, and coexists with other metamorphic minerals, suggesting a neogenic metamorphic mineral of granulite facies. The other occurs in the adjacent ultramafic rock unit, belonging to Cr_spinel. In thin sections, it is dark brown in color and is scattered among olivine, clinopyroxene and orthopyroxene as irregular grains, indicating a stable residual mineral in the process of granulite facies metamorphism.

After HRP application to the rostral area (n=10), quite a number of labelled cells were distributed at the ventrolateral part of the nucleus of trapezoid body, the lateroventral periolivary nucleus and the retrotrapezoid nucleus. After HRP application to the caudal area (n=10), HRP labelled cells were mainly located at the lateral reticular nucleus and the ventral part of at the lateral paragigantocellular nucleus LPGi. After HRP application to the intermediate area (n=6), only 8HRP labelled cells were observed at the in 6rats. After HRP application to the control area (n=4), only 6HRP labelled cells were found at the rostral ventrolateral reticular nucleus.

The square-on-square grids set diagonally of half MERO joint have been analysed and compared according to a design example and more than thirty projects already constructed. The conclusion is that the steel con- sumption for the square-on-square grid with a span of 30 metres or so is most economical; the size and height of grid are the important par- ameters which affect the steel consumption to a high degree.

So in order to improve ROP, the VTK vertical drilling technology of Baker Hughes was introduced. VTK is a kind of closed loop, automatic, and vertical drilling technology, made up of closedloop rotary steering drilling system AUTOTRAK, highperformance X-TREME motor and reliable MWD. It is able to return the well path back to vertical by adopting downhole microprocessors to analyze the measured deviation data and determine the proper force necessary for decreasing the deviation angle to guide the steering rib at the highside to reliably stick out against the upper wellbore.
