该研究的目的是分析种植距离和深度对小型骑行插秧机的动力输出(PTO)载荷谱的影响,以便对插秧机进行最佳设计。为了在实际种植过程中测量载荷数据,使用扭矩传感器、数据采集系统和逆变器开发了载荷测量系统。在土壤条件相似的田地里,选择了四种植距离(26 cm、35 cm、43 cm和80 cm)和三种种植深度(85 mm、105 mm和136 mm)进行了实地试验。使用雨量计数和Smith-Watson-Topper(SWT)方法将测量的载荷数据转换为载荷谱。再利用转换后的载荷谱和商业软件,根据不同的种植条件,对插秧机的安全因素进行了分析。所有种植条件的载荷谱显示,在108到109的高循环区域内,扭矩比相似。在不到108的低循环区域内,当种植深度增加,种植距离减小时,扭矩比增加。在所有深度条件下,PTO主动齿轮和从动齿轮的安全系数随着种植距离的增大而增加。在相同种植距离条件下,种植深度下降,则PTO齿轮的安全系数增加。考虑到不同种植条件下的工作负荷,该研究的结果可为插秧机PTO设计提供参考。

辣椒(Capsicum annuum)是美洲最古老的驯化作物之一,在全世界被广泛种植。本研究对CM334(墨西哥地方品种)进行了全基因组测序和组装(覆盖度为186.6×),同时还对另外两个栽培种和一个野生种分别进行了重测序和从头(de novo)测序。结果表明辣椒基因组大小约为番茄的4倍,辣椒基因组上存在大量gypsy转座子和花椰菜病毒家族元件的积累。结合转录组综合分析认为,辣椒素合成酶基因表达模式的改变及新功能化是导致辣椒素生物合成的原因,研究还发现辣椒与番茄在乙烯合成及果实成熟调控方面存在明显不同的分子模式。辣椒参考基因组的发布为辣椒营养品质和药用价值的改善提供了重要平台。

过量的钠摄入可以导致高血压、脑卒中和胃癌,而过量的钠摄入又主要是由于烹饪时盐的过量使用。韩国的研究者最近做了一项调查,评估学生餐中盐的含量以及比较学生和食堂职工对钠摄入量认知的不同。该研究从韩国京畿道的24所学校(包括9所小学、7所初中、8所高中)收集了382例食物,学生餐的盐含量根据每种食物的盐度和质量计算得来。小学、初中和高中每顿学生餐的盐含量分别为2.44g、3.96g和5.87g。仅学校的一顿午餐就已经提供了WHO推荐食盐每日摄入量的80%。从每餐饭的角度来说,面条、杂烩、调味酱和汤是食盐摄入的主要来源.并且调味酱、泡菜。

人工污秽绝缘子的闪络电压、污闪电压梯度和有效爬电系数均与其材质和型式有关。国内虽对污闪特性研究较多,但对不同绝缘子的有效爬电系数研究不多。文中在人工雾室中对五种典型结构的瓷和玻璃绝缘子的污闪特性进行了试验研究。根据试验结果分析和计算了五种典型绝缘子的闪络电压、闪络电压梯度、有效爬电系数。结果表明:在人工污秽试验条件下,不同型式绝缘子的污闪电压有较大差异,盐密对不同型式绝缘子的闪络电压的影响程度也有差异;三伞型绝缘子和玻璃绝缘子具有较高的闪络电压;不同绝缘子的有效爬电系数与其结构型式和材质有关,玻璃绝缘子的有效爬电系数高于瓷绝缘子,且玻璃绝缘子的有效爬电系数随污秽程度的增加而增加,而瓷绝缘子的有效爬电系数随污秽程度的增加而减小。
