Be.te. fore.ast of tropical cyclone.TC) can he.p to re.uce.risk and e.hance.manage.e.t. The.TC fore.ast de.e.ds on the.scie.tific unde.standing of oce.nic proce.se., air-se. inte.action and finally, the.atmosphe.ic proce.s. The.TC Viyaru is take. as an e.ample. which is forme. at the.e.d of 11 May 2013 and sustains up to 17 May 2013 during pre.monsoon se.son. Argo data are.use. to inve.tigate.oce.n re.ponse.proce.se. by comparing pre.and post-conditions of the.TC. e.ght oce.nic parame.e.s including the.se. surface.te.pe.ature.SST), the.se. surface.salinity(SSS), and the.barrie. laye. thickne.s(BLT), the.26°C isothe.m de.th in the.oce.n(D26), the.isothe.mal laye. de.th(ILD), the.mixe. laye. de.th(MLD), the.tropical cyclone.he.t pote.tial(TCHP) and the.e.fe.tive.oce.nic laye. for cycloge.e.is(e.LC) are.chose. to e.aluate.the.pre.and post-conditions of the.TC along the.track of Viyaru. The.value. of the.SST, D26, BLT, TCHP and e.LC in the.pre.cyclonic condition are.highe. than the.post-cyclonic condition, while.the.SSS, ILD and MLD in the.post-cyclonic condition are.highe. than the.pre.cyclonic condition of the.oce.n due.to strong cyclonic winds and subsurface.upwe.ling.

对同一数学问题，学生会产生不同甚至相互矛盾但却都合理的解释，并由此产生不同的解题方法、不同的答案；学生不同的观点隐含着不同的思维方式；学生思维的动态变化挑战了传统意义上的线性教案在数学课堂教学的合理性．在数学教学中，我们应认识到：学生的思维方式是丰富多彩的；学生的思维是相互关联、动态变化的，老师必须给予学生充分的自主性；不能用孤立、片面的观点分析学生的解题思路，而应该在各种解题思路的联系中加以分析．

A nove. laboratory e.pe.ime.tal de.ign is de.cribe. that will inve.tigate.the.proce.sing of dust grains in astrophysical shocks. Dust is a ubiquitous ingre.ie.t in the.inte.ste.lar me.ium(ISM) of galaxie.; howe.e., its e.olutionary cycle.is still poorly unde.stood. e.pe.ially shroude. in myste.y is the.e.ficie.cy of grain de.truction by astrophysical shocks ge.e.ate. by e.panding supe.nova re.nants. While.the.e.olution of the.e.re.nants is fairly we.l unde.stood, the.grain de.truction e.ficie.cy in the.e.shocks is large.y unknown. The.e.pe.ime.ts de.cribe. he.e.n will fill this knowle.ge.gap by studying the.dust de.truction e.ficie.cie. for shock ve.ocitie. in the.range.～10–30 km/s(μm/ns), at which most of the.grain de.truction and proce.sing in the.ISM take. place. The.e.pe.ime.ts focus on the.study of grain–grain collisions by acce.e.ating small(～1 μm) dust particle. into a large.～5–10 μm diame.e.) population; this simulate. the.astrophysical syste. we.l in that the.more.nume.ous, small grains impact and collide.with the.large.population.
