简介:这篇文章在优秀通货膨胀的存在下面与消费者参考质量效果学习联合定价和动态产品质量投资的一个问题。最佳的控制模型被构造与一个有限优秀投资能力最大化全部的利润,在需求对历史的产品质量水平敏感的地方。为有限、无限的计划地平线的最佳的优秀投资策略被根据Pontryagins最大的原则解决这些最佳的控制模型分别地给,它随着时间的过去与引用质量效果使最佳的优秀投资的准确轨道能被描绘。另外,一个有效算法被设计为系统产生最佳的联合定价和动态优秀投资政策。有限计划地平线和无限的计划地平线的策略之间的主要差别是后者是一个常数。我们的学习显示公司在整个计划地平线一路上增加优秀投资从来不是最佳的。当考虑参考质量的影响时,优秀投资的水平更高。而且,数字例子被给说明理论结果的正当。另外,敏感分析被执行显示出系统参数怎么影响最佳的政策,并且一些经理的建议被介绍。
简介:季节的垂直侧面结盟变化压力,温度,水汽,和踪迹气体(O_3,N_2O,公司,CH_4),在东亚区域上代表大气的条件直到100km的高度(30°-50°N,110°-150°E)被使用各种各样的观察数据,大气的热力学的参数的模型产量,和气体的集中构造。获得的东亚参考气氛的光特征与从典型中间的纬度夏天和冬季气氛的那些相比。在水汽地里,在夏天期间二模型气氛之间有主要差别,这被注意。结果的影响在在表面的到来的太阳的流动和在空气的顶的射出的陆上的流动上的水汽差别的夏天期间是14.3Wm~(-2)和6.5Wm~(-2),分别地。在另一方面,东方亚洲、中间的纬度气氛之间的冬季差别看起来不足道。为春天和秋天的参考气氛也是可得到的。利用是的构造大气的侧面输入到放射的转移模型,构造季节结盟气氛能更好便于的变化引用,这被期望对在东亚的光性质的描述。

简介:发烧友玩线已到达巅峰地步,十多二十年前一对发烧线要是卖三、两千元已被人批评为"发神经",不知是否神经线的名称由此而来?如今,一对高级的发烧线如TaraLabs、MIT、NBS、Cardas等随时是三数万身价,喇叭线更甚,MIT的EVO、KimberKable的黑珍珠动辄近十万元的叫价,差不多一对发烧线可买一个普通发烧友的整套音响组合,那究竟是否真的物有所值?相信这要视乎音响组合而论,在越高级的音响领域里,发烧神经线的重要性就越是不可忽略,以往发烧友单以为发烧线只是用作衬托音色,调味而已,但经过多年发烧线坛的各门各派,各大厂家花下去对线的研究及心血,把发烧线变成了是整套器材的其中一环,也不纯走调音色路线,不论在动态、频率延伸、音场、结像、分
