【目的】研究葡萄园行间生草对葡萄果实不同部位与葡萄酒中含氮化合物的影响。【方法】在酿酒品种赤霞珠葡萄园行间播种白三叶草、紫花苜蓿和高羊茅,以清耕为对照,在果实成熟期及酒精发酵结束后,采用凯氏定氮法及全自动氨基酸分析仪测定分析各处理葡萄果皮、果肉、种子及葡萄酒中的总氮、可溶性蛋白质及氨基酸含量。【结果】除紫花苜蓿处理使葡萄种子中可溶性蛋白质含量显著高于清耕(对照)外,行间生草总体使葡萄果皮、果肉及种子中的总氮和可溶性蛋白质含量降低,果实中不同部位总氮及可溶性蛋白质含量也有差异,种子中总氮含量最高,占葡萄果实总氮含量的41.6%,果肉与果皮分别占总氮含量的33.9%及24.5%;葡萄果实中可溶性蛋白质占总氮含量的46.0%,种子、果肉及果皮中可溶性蛋白质分别占果实中可溶性蛋白质总含量的50.9%、33.9%及15.2%;葡萄酒中总氮和可溶性蛋白质含量无显著差异。高羊茅和紫花苜蓿处理使葡萄果实中氨基酸总含量升高,白三叶草处理使其降低,但均无显著差异,各处理葡萄果实中均以脯氨酸含量最高,占氨基酸总含量的45.9%—56.9%,其次是赖氨酸和精氨酸,占氨基酸总含量的16.4%—24.2%。行间生草使葡萄酒游离氨基酸总含量升高,其中高羊茅处理最高,其次是紫花苜蓿处理,这两种生草处理与清耕之间差异达显著水平;各处理葡萄酒中的氨基酸,均以脯氨酸含量最高,占氨基酸总含量的90.11%—92.45%。【结论】行间生草使葡萄果实总氮和可溶性蛋白质含量降低,但总体提高了葡萄与葡萄酒中游离氨基酸总含量,有利于提高葡萄酒的质量。

目的了解CHINET中国细菌耐药性监测网儿童患者临床分离的不发酵糖革兰阴性杆菌的分布和耐药性变迁。方法按CHINET耐药监测统一方案使用纸片扩散法或商品化药敏试验自动测试仪进行药敏试验。按CLSI 2021年版标准判断结果。结果临床分离不发酵糖革兰阴性杆菌26987株中,主要以假单胞菌属和不动杆菌属细菌为主,其他各菌属均有不等检出。下呼吸道标本占51.1%,居于首位,脓液及伤口分泌物占16.5%,尿液标本占9.2%。这些菌株主要分离于内科病房(38.1%)、儿科ICU(26.8%)和外科病房(18.9%)。铜绿假单胞菌对氨曲南耐药率最高,为22.7%,对碳青霉烯类抗生素耐药率为15.6%,对其他抗菌药物耐药率均低于10%。碳青霉烯类耐药鲍曼不动杆菌检出率54.1%,明显高于铜绿假单胞菌的15.6%,2020年和2021年出现下降趋势。碳青霉烯类耐药铜绿假单胞菌在新生儿期患儿的检出率(34.7%)高于其他患儿;碳青霉烯类耐药鲍曼不动杆菌随患儿年龄增长检出率逐渐增高(39.9%~65.4%)。结论儿童分离铜绿假单胞菌和鲍曼不动杆菌对各种抗菌药物的耐药率呈锯齿形变化,对大多抗菌药物的耐药率有下降趋势。不同年龄段患儿中碳青霉烯类耐药菌株的检出率不同。不发酵糖革兰阴性杆菌的分布特征和不同菌属菌株的耐药特征存在差异。因此,在儿科对此类菌进行耐药监测十分必要。

基于应力函数法,对梯形分布载荷作用下、材料属性在厚度上任意变化的功能梯度简支梁弯曲问题的解析解进行了研究。首先引入了一个应力函数,根据平面应力问题的基本方程,得出了功能梯度梁的应力函数应满足的偏微分方程,并根据应力边界条件得出了应力函数及各向应力的表达式;进而根据功能梯度材料的本构方程和位移边界条件,得出了各向应变与位移的显式解析表达式。在算例中,分别采用文中方法和经典理论对均质各向同性梁进行求解,验证了文中方法的正确性;并求解了材料组分呈幂律分布的功能梯度梁的应力和位移分布,分析了上下表层材料的弹性模量比λ与组分材料体积分数指数n对应力和位移分布的影响。

研究了静水压力对粘弹性功能梯度材料与结构的力学性能的影响。基于粘弹性材料Boltzman-na积分型本构关系式,推导了静水压力作用下粘弹性功能梯度材料的本构关系,并假设其蠕变模量在结构厚度方向上连续变化,组分材料的体积分数呈幂律分布;在此基础上,研究了静水压力引起的粘弹性功能梯度结构横截面材料属性分布、厚度、刚度及功能梯度结构弯曲、屈曲和振动特性的变化,给出了恒定静水压力作用下,不同体积分数指数的粘弹性功能梯度结构厚度与刚度随时间变化的曲线。计算结果表明,在静水压力作用下,粘弹性功能梯度结构的厚度和刚度都发生了变化,并最终导致其弯曲、屈曲和振动性能都发生了较大的变化。

采用海水浸泡-阳光曝晒循环老化的方法,模拟实际海洋环境载荷对T300/环氧复合材料的作用,用以评价手糊成型T300/环氧复合材料在海洋环境中的耐久性。通过对老化前后复合材料的质量变化、轴向抗拉强度、拉伸模量、面内剪切强度及压缩强度等基本力学性能的分析,研究T300/环氧复合材料的老化规律。结果表明:经过湖北武汉和海南三亚140天的自然循环老化,增重率随时间的增加而增加,力学性能的衰减趋势基本一致,其中拉伸模量老化特征不明显,抗拉强度变化较小,然而面内剪切强度和轴向压缩强度衰减幅度较大,干态试件剩余强度大于湿态试件剩余强度。
