题述热塑性聚合物具有一羰基和一含氮的五元杂环基团于其侧链上。题述弹性组合物具有优异的循环(往复)性能，即使在变温下反复进行交联形成和交联解离，其物理性能也不变坏。该组合物的交联结构在室温下相当稳定，故有很高的抗拉强度。特别是当于五元氮杂环的3-或4-位上键合到主链上时，由于产生氢键，其硫化产物就具有很高的机械性能。

荷花坪锡多金属矿床是南岭中段湘南地区新发现的一个大型矿床，发育有印支期和燕山期2期成岩、成矿作用。文章对不同期矿石中的黄铁矿分别进行了稀有气体同位素研究。测试结果表明，印支期矽卡岩型矿石中的黄铁矿：^3He／^4He=0．15～2．49Ra，^30Ar／^36Ar=0．18733～0．18902，^40Ar／^36Ar=310．45～523．98,^20Ne/^22Ne=9．7279．830，^2Ne／^22Ne=0．0286-0．0310；燕山期蚀变碎裂岩型矿石中的黄铁矿：^3He／^4He=0．15～4．33Ra，^38Ar／^36At=0．18750-0．18843，^40Ar／^36Ar=331．78～602．62，^20Ne/^22Ne=9．736～9．858，^21Ne/^22Ne=0．0286～0．0305，显示区内两期成矿流体均为大气饱和水、地壳流体和地幔流体的混合流体。印支期矽卡岩型矿石中地幔He所占比例为2．34％～41．40％，平均18．16％；燕山期蚀变碎裂岩型矿石中地幔He所占比例为2．34％～72．12％，平均27．41％，燕山期幔源流体的作用强度略高于印支期。湘南地区印支期基性岩浆活动及荷花坪矿床印支期成矿过程中有幔源物质的参与，二者共同指示南岭地区中生代构造体制的转换或岩石圈伸展减薄可能始于印支主期（244230Ma）之后的224Ma左右，即晚三叠世。

AIM: To investigate executive function in Japanese adolescents and adults with autism spectrum disorders(ASD) compared to Japanese ***: Thirty-three individuals with ASD and 33 controls participated. The ASD and control groups' demographic variables were matched for gender(male/female: 20/13 vs 20/13), age(26.1 ± 11.5 vs 26.8 ± 9.6), years of education(13.2 ± 2.9 vs 14.2 ± 1.9), full-scale intelligence quotient(IQ)(103.0 ± 16.7 vs 103.7 ± 14.7), performance IQ(96.2 ± 16.1 vs 97.8 ± 15.0), and verbal IQ(107.9 ± 16.3 vs 107.7 ± 14.4). Participants performed the Wisconsin Card Sorting Test(WCST), which assesses the executive processes involved in problem solving and cognitive flexibility, and the Continuous Performance Test(CPT), which assesses attention and impulsivity. Symptoms were assessed by the Autism-Spectrum Quotient Japanese version(AQ-J). First, we compared the scores of the WCST between the groups using a Mann-Whitney U-test and conducted an analysis of covariance for the variables with the scores of category archives and CPT scores as covariates. Second, we analyzed the correlation between the scores of the WCST and the AQ-J in the ASD group using Pearson's ***: The total errors(TE) and the percentages of perseverative errors of the Milner type(%PEM) and Nelson type(%PEN) among the TE in the ASD group were significantly worse compared with the control group(ASD vs Control, respectively: TE: 16.0 ± 6.2 vs 12.6 ± 3.5, P = 0.012; %PEM: 11.7 ± 10.7 vs 6.6 ± 8.9, P = 0.037; %PEN: 20.1 ± 14.5 vs 8.7 ± 10.4, P = 0.0011). In contrast, no significant difference was observed between the two groups in the scores of categories achieved on the WCST or the CPT. An analysis of covariance revealed significant differences between the groups in the %PEN scores(P = 0.0062) but not in the TE or the %PEM scores. These results suggest that Japanese adolescents and adults with ASD have cognitive inflexibility. Furthermore, our results suggest that Japanese adol

背景AirwayScope（AWS）和Airtraq（ATQ）喉镜的镜片结构相似，在本次研究中，我们评估了无操作经验的人员在模拟人困难气道模型上分别应用AWS、ATQ和Macintoshlamgoscope（ML）喉镜所完成气管插管的难易性。方法24名无气管插管经验的5年级医学生参加了此项研究，采用人体模型（SimMan）来模拟各种不同的困难气道，包括颈椎强直、张口受限、咽部阻塞3种场景。气管插管装置及困难气道类型的顺序是随机的。我们分析了气管插管的成功率，声门暴露、气管插管、张肺所需的时间，调整手法使用次数和摩擦牙齿的喀声次数。24名学生用3种不同的插管装置在4种不同的气道条件下进行操作。结果与ML组相比，AWS组、ATQ组均有较高的气管插管成功率（AWS组为100％，ATQ组为98％，ML组为89％，AWS组、ATQ组与ML组相比P〈0．05），AWS组所需的插管时间显著少于ATQ组和ML组（AWS组为11±6秒，ATQ组为16±12秒，ML组为16±11秒），与ATQ组和ML组相比，AWS组需要优化调整的次数显著减少（P〈0．05），ML组插管过程中可闻及的牙齿喀声比AWS组和ATQ组显著增多。结论对于在模拟困难气道下进行气管插管的无插管经验的人员，AWS和ATQ可能是更适合的插管装置，有必要在今后的临床实践中进一步证实此项发现。

目的:探讨不同石灰添加量对苍术产量、质量的影响,为苍术的生长立地土壤改良和自毒缓解提供参考。方法:添加不同梯度的生石灰,然后测量其生长指标、产量和茅术醇、苍术酮、β-桉叶醇、苍术素4种挥发性有效成分的含量,计算单株挥发性有效成分产量。结果:添加160 g/m2的生石灰对苍术的各项生长和产量产生了显著地促进作用。添加80 g/m2的生石灰对苍术的挥发性有效成分的生成产生了促进作用,并且苍术酮和苍术素含量比例降低、茅术醇和β-桉叶醇含量比例升高;添加160 g/m2的生石灰对苍术的挥发性有效成分产量有促进作用。结论:添加石灰能起到中和土壤酸碱度、抑菌和防治根结线虫的作用,对苍术的自毒和连作障碍起到一定程度的缓解,进而对苍术产量和挥发性有效成分的生成起到了显著地促进作用。
