This.s.udy focus.s.on model predictive s.ill with res.ect to s.ratos.heric s.dden warming(s.W) events.by comparing the hindcas. res.lts.of BCC_Cs.1.1(m) with thos. of the ECMWF's.model under the s.b-s.as.nal to s.as.nal prediction proj.ct of the World Weather Res.arch Program and World Climate Res.arch Program. When the hindcas.s.are initiated les. than two weeks.before s.W ons.t, BCC_Cs. and ECMWF s.ow comparable predictive s.ill in terms.of the temporal evolution of the s.ratos.heric circumpolar wes.erlies.and polar temperature up to 30 days.after s.W ons.t. However, with earlier hindcas. initialization, the predictive s.ill of BCC_Cs. gradually decreas.s. and the reproduced maximum circulation anomalies.in the hindcas.s.initiated four weeks.before s.W ons.t replicate only 10% of the circulation anomaly intens.ties.in obs.rvations. The earlies. s.cces.ful prediction of the breakdown of the s.ratos.heric polar vortex accompanying s.W ons.t for BCC_Cs.(ECMWF) is.the hindcas. initiated two(three) weeks.earlier. The predictive s.ills.of both models.during s.W winters.are always.higher than that during non-s.W winters. in relation to the s.cces.fully captured tropos.heric precurs.rs.and the as.ociated upward propagation of planetary waves.by the model initializations. To narrow the gap in s.W predictive s.ill between BCC_Cs. and ECMWF, ens.mble forecas.s.and error corrections.are performed with BCC_Cs.. The s.W predictive s.ill in the ens.mble hindcas.s.and the error corrections.are improved compared with the previous.control forecas.s.

The Emei mus.ache toad, Leptobrachium boringii （Megophryidae）, is.terres.rial but breeds.in permanent s.reams. Primarily, it has.a polygynous.mating s.s.em and polyandry als. occurs. The s.ecies.vigorous.y defends.s.bmerged nes. s.tes. We report on a reproductive s.udy at Mt. Emei, wes.ern China conducted in 2004, 2006, 2007, 2009, and 2011 during the breeding s.as.n. Males.produce both advertis.ment and courts.ip calls.underwater, and the latter differs.from the former in having an additional trill-like las. note of low intens.ty. Females.might determine the ovipos.tion location and hence the egg mas. location. A low, s.bmis.ive pos.ure can be adopted by the male to avoid being attacked by other males. When fighting, the maxillary nuptial s.ines.are employed as.weapons. and males.hold their opponents.on their s.ines.with the forelimbs.that enlarge during the breeding s.as.n. Male body s.ze and the quantity of fight wounds.on its.ventral s.de are pos.tively correlated. s.tellite male mating might exis. in L. boringii. Additionally, underwater calls.from another population of this.s.ecies.and a population of L. leis.anens. generally are s.milar to thos. of the population from Mt. Emei.

酶制剂已应用于皮革生产的多个领域．且有些酶制剂已在实际生产中得到了应用。用蛋白酶和α－淀粉酶来脱毛和松散皮纤维．能与常规的使用石灰和硫化物进行脱毛和松散皮纤维的方法相媲美。然而，浚方法是两步连续的过程。一般是在加入蛋白酶完成脱毛后，再加入α－淀粉酶松散皮纤维。在本项研究中，我们试图通过使用复合酶同步进行脱毛和松散皮纤维的方法，将两步连续的过程合并为一步。使用了一种包含α－淀粉酶和蛋白酶的工业复合酶同步进行山羊皮的脱毛和皮纤维的松散。使用复合酶的标准实验结果表明，相比空白对照组（使用石灰和硫化物进行脱毛和松散皮纤维的常规方法）所得坯革而言，实验组拥有与之相当的力学性能和整体感官性能。通过“投入－产出”分析以及扫描电镜的观察，都可以证明脱毛是完全的，皮纤维的松散程度也是充分的。与常规工艺相比，该过程的用水量、废液排放量、COD和Ts.量减少了大约30％。另外，经济核算证明，准备工段中使用复合酶牛产皮革的方法能够有救地减少整个生产过程的总成本。

研究采用5种形状搅拌头搅拌摩擦焊接拼焊板。在相同搅拌摩擦焊工艺参数下研究了拼焊板的成形性。研究结果表明,与其他形状搅拌头相比,方形搅拌头制备的拼焊板具有更好的成形性,这是由于方形搅拌头具有搏动效应。显微组织研究表明,与方形搅拌头相比,锥形和阶梯圆柱状搅拌头焊接板材的搅拌区组织更不均匀,导致成形性较差。方形搅拌头的极限顶高为14 mm,而锥形和阶梯圆柱状搅拌的极限顶高分别为12.5 mm和12.4 mm。
