简介：紫色米饭是为米饭消费者的bioactive抗氧化剂的来源。在煮过程的一个范围以后的主要抗氧化剂混合物的损失被在anthocyanin集中(ATC)和抗氧化剂能力(DPPH活动)测量变化评估四非粘并且四粘的遗传型。然而，在煮以前在水里浸泡通常减少了更多的ATC和抗氧化剂能力在比在粘的遗传型非粘。湿煮(WC)并且(S-WC)在湿煮以前，浸泡导致了与在遗传型之间的仅仅细微的变化失去几乎所有ATC和抗氧化剂能力。在粘的遗传型Pieisu，它有最高未加工的米饭ATC，ATC留下了最高当由WC方法煮了时。由对比，几乎，没有ATC在WC和S-WC以后留在象KumDoiSaket那样的低ATC遗传型。总的来说，ATC的损失是更大的在比在为WC和S-WC方法，而是颠倒的粘的遗传型非粘为抗氧化剂能力发生了。用电的米饭炊具的WC比煮的压力保留了更高的ATC。因此为有高ATC和抗氧化剂能力的遗传型，煮方法的选择为保留并且稳定米饭质量是批评的。

简介：概括波浪活动密度，被定义为三维的涡度向量不安和一般潜在的温度不安的坡度的生产的绝对值，被介绍，它的波浪活动法律在笛卡儿的坐标被导出。在agoestrophic和nonhydrostatic构造了动态框架，概括波浪活动法律可能是适用的诊断导致重降雨的mesoscale天气系统。概括波浪活动密度和波浪活动流动分叉与客观分析数据被计算在重降雨的区域上调查波浪活动的字符。为与重降雨联系的骚乱负责的主要动态过程也被分析。概括波浪活动密度密切被相关到观察6-h，这被显示出积聚的降雨。这显示波浪活动或骚乱是明显的在上正面并且乍见陆地台风在中间、更低的对流层的重降雨的区域。为乍见陆地台风雨线，概括波浪活动流动分叉的部分，表示在基本状态的气旋的发行量之间的相互作用乍见陆地，台风和mesoscale飘动，是为概括波浪活动的进化负责的主要动态过程密度。

简介：基于改进客观气旋察觉和追踪的算法，在在北东亚的热带以外的气旋的十的变化被使用ECMWF40年分析(ERA-40)学习海平面的压力数据在期间19582001。结果表明那项热带以外的气旋活动显示了清楚季节，内部在北东亚的年度、十的可变性。春天是气旋最经常发生的季节。热带以外的气旋的空间分发证明气旋主要在40°以内发生50°N在北东亚的纬度的乐队，和出现的最经常的区域在蒙古。而且，这研究也揭示热带以外的气旋的频率显著地在北东亚的更低的纬度区域减少了在期间的事实19582001，但是十的可变性在更高的纬度乐队统治了，与经常的气旋开始。热带以外的气旋的紧张在一个年度、季节的基础上减少了。在北东亚的气旋的年度数字的变化与baroclinic的吝啬的紧张被联系正面的地区，它被在更高的纬度温暖的气候影响。而且，随北方的增加和在北东亚的南部的部分的减少，额外的热门气旋变化的偶极子结构与有关向北方baroclinic的运动110°E的任何一个方面上的正面的地区。
