Effect of lubricant on crystal morphology of surface layer of PP;

°Surface layer±, a new con- cept to define the space along street, could make compli- cated problems easily revealed.

The X-ray photoelectron spectroscopy (XPS) analysis show that the surface layer of the CTA-annealed film contains much non-perovskite BST phase, and has a thickness of 3~5nm approximately; while the RTA annealed surface layer contains much lower non-perovskite BST ph.

In order to analyze the street sighting synthetically and quantificationally, this paper advanced the concept of surface layer.

Variations of surface and subsurface heat contents in Indian Ocean and their relationship to ENSO based on SODA data;

College students,however,as a special colony,often have the phenomena of surface reading or over-reading in annotating the text.

The surface morphology and surface structure of the roller were analyzed by surface copying technology,metallography and scanning electronic microscope.

The drilling shoe is the key technology of surface casing drilling.

This paper presents the design of surface casing drilling in Shengli Oilfield,as well as development of main tools and the field application in Well Kendong-341.

Application of pint-size surface casing in the Course of Drilling in Bamianhe Oilfield is successful by the contrast of before surface casing and the present pint-size surface casing,as well as practical effect in production.
