Indicated according to the near two year gauge block anti-curved experiment, when the design intensity takes 435 N/mm2, under the normal running condition the reinforcement stress probably is 343 N/mm2, the corresponding average crack opening approximately in the 0.14~0.15mm scope, if takes 1.66 to multiply the big coefficient, the short-term maximum crack opening reaches 0.24mm, considered the long-term function rides 1.5 to multiply the big coefficient again, final crack opening approximately in 0.36mm.
根据近两年对板的抗弯试验表明,当设计强度取 435 N / mm2,正常使用状态下钢筋应力大约为 343 N / mm2,对应的平均裂缝宽度大约在0.14~0.15mm 范围,如取1.66倍增大系数,短期最大裂缝宽度达 0.24mm ,考虑长期作用再乘1.5倍增大系数,最终裂缝宽度大约在0.36mm 。

The protein encoded by this sequence was deduced to be consisted with 213 amino acids, signal peptide sequence from 1 to 17 position, and transmembrane regions from 171 to 190 position, whose grand average of hydropathicity is computed to be 0.031, secondary structure is composed by alpha helix (57.28%), extended strand (6.57%) and random coil (36.15%), subcellular localization was cytoplasmic by CELLO v.2.5. There are some function sites predicted by PROSCAN software, such as one N-glycosylation site (151-154aa), one protein kinase C phosphorylation site (193-195aa), two casein kinase II phosphorylation sites (155-158aa and 173-176aa), and one N-myristoylation site (97-102aa).
推测编码蛋白由213个氨基酸组成,信号肽序列位于1-17aa,亲水性指数为0.031,跨膜区域位于171-190aa,二级结构由-螺旋(57.28%)、延伸主链(6.57%)和无规卷曲(36.15%)组成;亚细胞定位于细胞质,含有N-糖基化位点1个(151-154aa),蛋白激酶C磷酸化位点1个(193-195aa),酪蛋白激酶Ⅱ磷酸化位点2个(155-158aa and 173-176aa),N端酰基化位点1个(97-102aa)。

In viewof geological records preserved from different regions of the world are not identical, its suggested that, whencorrelating the Ordovician-Silurian boundary, at the global boundary stratotype section, the FAD of N.persculptus be selected as the biomark, the transgression event identical to the FAD of N. persculptus as theauxiliary physical mark and the mass extinction and chemical anomaly events respectively as the auxiliarybiomark and chemomark. In some regions with few graptolite, the Ordovician-Silurian boundary should beindicated by the auxiliary marks, such as the transgression event, mass extinction or chemical anomaly event,with the other fossil such as conodont nearest to other geological events as the provincial biomark forcorrelation. In other regions with much stratigraphic hiatus originated from the regression, theOrdovician-Silurian boundary should he marked by the regression-transgression event nearly relevant to the N.persculptus Zone.
鉴于不同地区留下的地质记录不完全相同,奥陶/志留系界线对比方法不同:在界线层型剖面上,以N.persculptus的首现为生物标志,以与之基本一致的海侵事件为辅助的物理标志,以生物集群绝灭事件和化学异常事件为辅助的生物和化学标志;在笔石极不发育的地区,则以海侵事件、生物绝灭事件或化学异常事件为辅助标志,以与其相距最近、并且具有区域对比性的其它门类化石作为界线对比的生物标志;对于由于海退事件所造成地层缺失很多的地区,则以海退/海侵事件作为划分界线的物理标志,并以相映的海侵事件的开始作为奥陶/志留系的分界。

The improved e-N method can also yield results well agree with those obtained by DNS.4 The transition prediction for boundary layers on cones with different key parameters such as angle of attack, cone half angle and the Mach number of the coming flow, have been made, to show the reliability of the modified e-N method.5 For the calculation of base flow, boundary layer equations can be used in the case of small angle of attack.
但是它要依赖于对初始扰动的正确预估,这显然又取决于更多飞行数据的积累和分析。e-N方法的转捩预测结果与直接数值模拟得到的结果也吻合较好。4通过对不同来流攻角、不同半锥角和不同马赫数的三维圆锥边界层的转捩位置进行预测,证实了改进的e-N方法对于三维边界层转捩预测是可靠的。5对于基本流的计算,边界层方程可以用于小攻角的情况,其计算量远远小于直接数值模拟,但背风面的剖面不可靠。

These methanols were treated with BF3 in CH2Cl2 to generate the diferrocenylmethyl carbocations. Without separation from the reaction mixture, the ions were treated with some amines RNH2 [R=C2H5, n-C3H7, n-C4H9, HOCH2CH2, HOCH(CH3)CH2, HOCH2CH(C2H5)] to afford the ferrocenylamines in high yields. The present methodology for preparing α-ferrocenylamines from α-ferrocenyl alcohols enjoys such advantages as simple procedure and inexpensive starting materials.
它们对酸的敏感性很高,与BF3在二氯甲烷中作用可形成稳定的二茂铁基甲基碳正离子,无需从溶液中分离出来,便可与胺RNH2[R=C2H5,n-C3H7,n-C4H9,HOCH2CH2,HOCH(CH3)CH2,HOCH2CH(C2H5)]作用得到产率颇高的二茂铁基胺,这种由α-二茂铁基醇制备α-二茂铁基胺的方法具有简单、快速和原料廉价的特点。
