The initial Os and Nd isotopes of high-Ti/Y type picrites are consistent with those of magmatic rocks related to plume, indicating that they were derived from a mantle plume and experienced little contamination with a continental crust and SCLM, therefore, most probably representing Re-Os composition of a primary melt.

木里高Ti／Y型苦橄岩具有高的γOs值以及εNd_(t值，与全球地幔柱成因的岩浆岩石的初始Os同位素比值(γOs=+5～+10)一致，表明它们形成于地幔柱源区，而且它们几乎没有受到地壳或是陆下岩石圈地幔的混染。

It is treated with six fields (Anterior, Posterior, four obliques) positioned 60° apart around the circumference of the patient, each dual field is made up of two component beams, pointing ±15° with respect to the horizontal. The nominal energy of electron beam produced by Mevatron Ⅻ is 3MeV, and the patient is treated at a distance of 3 meters. Using Capintec dosemeter and PS-033 electron beam chamber for measurement, one moniter unit of radiation is equivalent to 0.0127cGy. Measurement of electron energy by Kodak X-omat-V verification film inside the Rando phantom at 100 cm SSD was 3.70MeV, electron energy measured at 3 meters was 3.51MeV. X-ray contamination was measured as 9.5% per six dual fields.
