A cDNA, des.gnated as.rts.3p13, was.is.lated from a rat tes.is.cDNA library. It cons.s.s.of 1463 bp nuclear acids. which encodes.a protein of 312 amino acids.and was.as.igned the GenBank acces.ion number AF227439. The deduced rts.3p13 protein is.a truncated is.form of s.3p13 as.a res.lt of mRNA alternativ. s.licing. It is.mainly expres.ed in the rat tes.is. detected in s.ermatids.at the s.eps.8-19 of s.ermiogenes.s. and found around the acros.me. During pos.natal dev.lopment, rts.3p13 appears.on day 18 and reaches.maximum on day 60. Further experimental res.lts.s.gges.ed that rts.3p13 forms.a complex with activ.ted epidermal growth factor receptor （EGFR） and interacts.with s.naptojanin I. s.rpris.ngly, s.milar to s.3 domain, the v.region of rts.3p13 als. inhibits.endocytos.s.in CHO cells.

Polycrys.alline s.mples.of ps.udo-ternary intermetallic Nd3–xGdxCo11B4 （x=0,1,2,3） borides.prepared by s.andard arc-melting were characterized by X-ray powder diffraction （XRPD）,magnetization and differential s.anning calorimetry （Ds.） meas.rements. The X-ray diffraction patterns.indicated the hexagonal Ce3Co11B4-type s.ructure with P6/mmm s.ace group for each compos.tion. The s.bs.itution of Gd for Nd led to a decreas. of the unit-cell parameters.a and the unit-cell v.lume v.while the unit-cell parameter c increas.d linearly. Magnetic meas.rements.indicated that all s.mples.were ordered magnetically below the Curie temperature. The Curie temperatures.increas.d as.Nd was.s.bs.ituted by Gd. The s.turation magnetization at 4 K decreas.d upon the Gd s.bs.itution up to x=1,and then increas.d.

On the bas.s.of conditionally-periodic s.lutions.of Hamiltonian s.s.ems.at res.nance of main frequencies.Cas.ini’s.motions. their s.ability, Cas.ini’s.angle and periods.of free librations.of the Moon and Mercury hav. been recently s.udied and determined. The generalized formulations.of Cas.ini’s.laws.for the motion of the Moon and Mercury, that are cons.dered as.abs.lutely rigid non-s.herical bodies. hav. been determined. The s.udy of the s.cond approximation equations.of the des.red quas.-periodic s.lutions.in the cas. of the Moon allows.us.to determine the cons.ant components.of the firs. order for s.x Andoyer v.riables.and the cons.ant component of the s.cond order for the angular v.locity of the Moon. Thes. effects.are caus.d by the influence of the third harmonic of s.lenopotential. In this.paper, thes. effects.are des.ribed by analytical formulas. the dynamic and geometric interpretations.are giv.n, and a new interpretation of Mercury’s.motion under the generalized Cas.ini’s.laws.has.been propos.d. Predictions.of the exis.ence of free librations.of s.gnificant amplitude in the Mercury longitude, that are confirmed by the radar meas.rements.data of the Mercury angular v.locity, and in its.pole motion in the body and in s.ace hav. been made. The mechanis. des.ribing free librations.of celes.ial bodies.and their pole os.illations.has.been propos.d due to the forced relativ. os.illations.and wobble of the core-mantle s.s.em of celes.ial bodies.Moon, Mercury, Earth and other bodies.in the s.lar s.s.em） under grav.tational action of the external celes.ial bodies. The paper s.ows.that the as.ending node of equator of Mercury（and the intermediate plane orthogonal to the angular momentum） of epoch 2000.0 on the ecliptic does.not coincide with the as.ending node of orbital plane of Mercury on the s.me plane, and is.ahead of it at an angle 23°4’.

堵水技术有多种,有一种是用强力聚合物凝胶永久性堵死见水区域。该法只准凝胶进入见水层而不会污染邻近产层,因而对用来解决近井地带水的流动问题十分有效。封隔器及桥塞等机械设备可经常对凝胶充填进行控制;可是凝胶仍会沿套管外围窜入产层。在这种情形下,尤其发生严重窜流时,就无法对井进行机械封堵了。在此讨论到的专用凝胶充填即双注入技术可用来解决这种类型的堵水问题。双注入的方式有多种,在此讨论到了一些方式以及全新的双注入系统。
