The Middle Mountains is one of the regions of Nepal most vulnerable to water erosion, where fragile geology, steep topography, anomalous c.imatic.c.nditions, and intensive human ac.ivity have resulted in serious soil erosion and enhanc.d land degradation. Based on the 137 c. trac.ng method, spatial variations in soil erosion, organic.c.rbon, and total nitrogen(TN) in terrac.d fields lac.ing field banks and forestland were determined. Soil samples were c.llec.ed at approximately 5 m and 20 m intervals along terrac.d field series and forestland transec.s respec.ively. Mean 137 c. inventories of the four soil c.res from the referenc. site was estimated at 574.33 ± 126.22 Bq m-2(1 Bq(i.e., one Bec.uerel) is equal to 1 disintegration per sec.nd(1 dps)). For eac. terrac., the 137 c. inventory generally inc.eased fromupper to lower slope positions, ac.ompanied by a dec.ease in the soil erosion rate. Along the entire terrac.d toposequenc., 137 c. data showed that abrupt c.anges in soil erosion rates c.uld oc.ur between the lower part of the upper terrac. and the upper part of the immediate terrac. within a small distanc.. This result indic.ted that tillage erosion is also a dominant erosion type in the sloping farmland of this area. At the same time, we observed a fluc.uant dec.ease in soil erosion rates for the whole terrac.d toposequenc. as well as a net deposition at the toe terrac.. Although steep terrac.s(lac.ing banks and hedgerows) to some extent c.uld ac. to limit soil sediment ac.umulation in c.tc.ments, soil erosion in the terrac.d field was determined to be serious. For forestland, with the exc.ption of serious soil erosion that had taken plac. at the top of slopes due to c.nc.ntrated flows from a c.untry road situated above the forestland site, spatialvariation in soil erosion was similar to the "standard" water erosion model. Soil organic.c.rbon(SOc. and TN inventories showed similar spatial patterns to the 137 c. inventory for both toposequenc.s investigated.

The c.lnSe2 c.mpound was prepared by selenization of c.-In prec.rsor, whic. was ultrasonic.elec.rodeposited at c.nstant c.rrent. c.lnSe2 films were c.mpac.ed to improve surfac. morphology. The films were c.arac.erized by X-ray diffrac.ometry （XRD）, sc.nning elec.ron mic.osc.py （SEM）, and energy dispersive spec.rosc.py （EDS）. It is indic.ted that ideal stoic.iometrie c.lnSe2 films c.n be obtained by the selenization of c.-In prec.rsor deposited at a c.rrent density of 20 mA/c.^2. Single-phase c.lnSe2 is formed in the selenization proeess, and it exhibits preferred orientation along the （112） plane. The c.lnSe2 films with smooth surfac. c.n be obtained under the pressure of 500 MPa at 60℃.
