% RH是什么意思啊？
%RH是相对湿度的单位。相对湿度（Relative Humidity ），用RH表示。表示空气中的绝对湿度与同温度和气压下的饱和绝对湿度的比值，得数是一个百分比。也就是指某湿空气中所含水蒸气的质量与同温度和气压下饱和空气中所含水蒸气的质量之比，这个比值用百分数表示。相对湿度是单位体积空气内实际所含的水气密度（用d1 表示）和同温度下饱和水气密度（用d2 表示）的百分比，即RH（%）= d1/ d2 x 100%；另一种计算方法是：实际的空气水气压强（用p1 表示）和同温度下饱和水气压强（用p2表示）的百分比，即RH（%）= p1/ p2 x 100%。扩展资料日常生活中的合适数值：夏天，室内相对湿度过大时，会抑制人体散热，使人感到十分闷热、烦躁。冬天，室内相对湿度大时，则会加速热传导，使人觉得阴冷、抑郁。所以，专家们研究认为，相对湿度上限值不应超过80%，下限值不应小于30%。通过实验测定，最宜人的室内温湿度是：冬天温度为20至25℃，相对湿度为30%至80%；夏天温度为23至30℃，相对湿度为30%至60%。在此范围内感到舒适的人占95%以上。在装有空调的室内，室温为20至25℃，湿度为40%至50%时，人会感到最舒适。参考资料来源：百度百科——相对湿度
rh是什么意思啊
RH指相对湿度。指空气中水汽压与相同温度下饱和水汽压的百分比。或湿空气的绝对湿度与相同温度下可能达到的最大绝对湿度之比。也可表示为湿空气中水蒸气分压力与相同温度下水的饱和压力之比。最原始的温湿计就像是老式医疗用的那种温湿度计，测定干球温度，然后与湿球温度比较差度（即干湿差。当温度一定时，干湿差大，表示空气中湿度小），在刻度盘中查出现在实际的相对湿度的值，来得知现在空气的湿度状态。现在大部分采用特种感温感湿材料制成的温湿计，有的更加上机械旋转装置构成温湿自动记录仪，CCTC 现在普遍使用这种温湿记录仪。

；这个符号什么意思啊？
这个是分号。分号“；”是一种在层次上介于逗号和句号之间的标点符号，主要用以分隔存在一定关系的两句分句，正确的使用方法有如下5种。一 在单重复句中使用分号单重复句是指只有一重关系的复句。在并列关系的单重复句中，分句不包含逗号时，可以用逗号或分号分隔，效果一样。包含逗号时最好用分号分隔。并列复句内部分句之间的停顿用分号，停顿要比逗号长。如：他上课认真听讲，积极回答问题；下课完成作业，复习当天所学知识。上句中有两个分句包含了逗号，所以各分句用分号分隔。如：她的身姿格外挺拔；她的微笑如此动人。上句中可用逗号，也可用分号，是分号的一般用法。注意：分号是句内的标点符号，在句群中的并列关系不能用分号。二 在多重复句中使用分号多重复句是一般复句的拓展形式，在结构上有两个以上的层次，表示两种以上的意思关系。分隔这种多重复句第一层次的分句时用分号，无论该层次若干分句的逻辑关系是什么。如：内容有分量，尽管文章短小，也是有分量的；如果内容没有分量，尽管写得多么长，愈长愈没有分量。上句是表示了多层关系的多重复句，第一层关系是“有”和“没有”的对比，因此这层关系用分号。如：如果有篇文章，有的只是华丽的辞藻，有的只是庞杂的材料，却并不能说明什么问题，解决什么问题，人们读过以后，根本不知道作者赞成什么，反对什么；那样的文章，人们通常称之为“没有观点”的文章，也就是没有灵魂的文章。上句是非并列关系的多重复句，第一层关系是“假设”关系，如果......那样......尽管不是并列关系，也使用分号分隔。三 在并列分句中使用分号大句中被冒号、破折号、括号、引号分隔出来的并列分句有相对的独立性，中间可根据需要使用分号。如：这时月亮和山的阴影，对比得异常明显——山是墨一般的黑，陡立着，倾向江心，仿佛就要扑跌下来；而月光，从山顶上，顺着深深的、直立的谷壑，把清光泻到江面。上句的大句中用破折号引出的解释说明部分是并列分句，可以用分号进行分隔。如：在介绍成都金沙遗址博物馆的特性时，通过两件典型的出土文物（商周太阳神鸟金饰，整体圆形，厚度均匀，图案镂空；商周大金面具，金质，立体脸谱，脸部丰满，表情威严），具体说明了作为国家AAAA级旅游景区的不同寻常之处。上句在大句中需要说明的内容使用了括号，括号内的话是并列分句，可以用分号进行分隔。四 在列举分项时使用分号分项列举各项如果是分句，自然可以用分号。在单句中冒号引出的并列短语用于分项列举，可以用分号分隔，使得分项的性质显得突出。如：写作前的需要通过思考进行的准备，不外乎有以下几处：（1）立意；（2）选材；（3）结构；（4）顺序。上句列举的各项是名词，前面有序次语。各项之间本可用逗号，用分号是为了突出各项的性质。五 在解释词语不同释义时使用分号这个使用方法在辞书中通见，辞书的条目在同一释义项下有三个及以上释义时常用分号分隔。同一义项中的释义，含义相近的用逗号分开，较远的用分号。
问一下，这个符号是什么意思？
逗号是一种表意停顿的标点符号，停顿小于分号大于顿号，可把句子切分为意群。逗号在汉语及大多数外语是使用频率最高的标点符号，朝鲜语使用句号多于逗号属于特殊情况。逗号的用途最广泛，用法最灵活，因此也最难掌握。比较和分析国内外有关资料，有助于了解逗号的主要功能。基本信息中文名逗号外文名Comma别名逗点形式“、”读(dòu)号1释义本称读（dòu）号，有时亦称逗点，表示一句话中间的一般性停顿间隔。2汉语用法句子内部主语与谓语之间如需停顿，用逗号。例如：我们看得见的星星，绝大多数是恒星。句子内部动词与宾语之间如需停顿，用逗号。例如：应该看到，科学需要一个人贡献出毕生的精力。句子内部状语后边如需停顿，用逗号。例如：对于这个城市，他并不陌生。复句内各分句之间的停顿，除了有时要用分号外，都要用逗号。例如：据说苏州园林有一百多处，我到过的不过十多处。用来分开句内各词语或表示语气的停顿。提示：“，”不可放在一行之首或开头。并列词语之间带有“啊”“呀”“啦”等语气助词时，并列成分之间用逗号，不用顿号。例如：八月的大街上摆满了水果，像甜瓜啊，西瓜啊，苹果啊，葡萄啊......并列成分做谓语时，如果并列成分是主谓结构，那么并列成分之间用逗号。例如：她衣服新潮夺目，头发齐耳根长，走起路来风风火火，讲起话来大声大气。3外文用法逗号逗号不再是中文中的全角格式“，”，而变成了半角格式“,”。在英语逗号（即comma）和撇号（Apostrophe）“'”和右引号“'”的外形很相似，但贴底线书写；在汉语它的形状为“，”，一般置中或置底，并占一大格；在日语它和汉语中的顿号形状相同。但汉语的逗号同其他语言不同，分隔并列的词汇另有顿号。而在大部分语言中，“,”都可用来分隔并列的词汇。在部分欧洲语言，“,”可以视为小数点。在英语，它亦可表示超过三位的大数，每三个数字分隔起来以便阅读；现多以空白分隔。因为他们在读大数时是以千进位的，一千个千为一个million,一千个million为一个billion，一千个billion为一个trillion。大概英国人在与大额数字打交道时也遇到了与我们一样的烦恼，于是想出了这么个好办法。英语国家的人有了千分号，哪怕是十位数字也能轻而易举地读出来。不知从什么时候，千分号被引进了中国，但并不能解决中国人读数难的问题。因为中国人读数的习惯是以万进位，一万个万为一亿，一万个亿为一兆。如果要引进，也应引进人家的思想和原理，结合中国的实际来一个“引进消化吸收再创新”。本着这个思想，有人向出版部门提出一个建议，在出版物中的大额数字中取消千分号，而代之以“万分号”，即对大额数字由右至左每隔四位数用一个逗号分开。这样，中国人就不会再为读大数而烦恼了。英语用法用逗号连接两个句子的时候，必须加连词，因为一个主句不能有两个谓语，除非加了连词把它变成并列句或者主从句如果想把这个句子继续写下去但又不想加连词，还可以加分号，这两个半句之间没有连接关系但依然是一句话。因为加了分号之后这两句还是一句话，所以分号后面不用加主语除此之外就得加句号。
下列关于Rho的性质说法正确的有( )。
【答案】：B,C,D
Rho的性质如下：①看涨期权的Rho是正的，看跌期权的Rho是负的；@Rho随标的证券价格单调递增；③对于看涨期权，标的价格越高，利率对期权价值的影响越大；④对于看跌期权，标的价格越低，利率对期权价值的影响越大；⑤越是实值(标的价格>行权价)的期权，利率变化对期权价值的影响越大；⑥越是虚值(标的价格<行权价)的期权，利率变化对期权价值的影响越小；⑦Rho随着期权到期，单调收敛到0，也就是说，期权越接近到期，利率变化对期权价值的影响越小。
下列关于Rho的性质说法正确的有( )。
【答案】：B,C,D
Rho的性质如下。
①看涨期权的Rho是正的，看跌期权的Rho是负的。
②随标的价格的变化：Rho随标的证券价格单调递增。对于看涨期权，标的价格越高，利率对期权价值的影响越大；对于看跌期权，标的价格越低，利率对期权价值的影响越大。越是实值(标的价格>行权价)的期权，利率变化对期权价值的影响越大；越是虚值(标的价格<行权价)的期权，利率变化对期权价值的影响越小。
③随时间的变化：随着期权到期，Rho单调收敛到0。也就是说，期权越接近到期，利率变化对期权价值的影响越小。
HRO是什么意思？
HRO即人力资源外包。
人力资源外包作为一种管理模式，早在20世纪60年代的美国就出现了，其中分成4个板块：研发外包，管理外包，生产外包，营销外包。人力资源外包只是管理外包的一种，因为人力资源活动的独特性主要体现在组织的独有性和外部的稀有性。在企业结合自身经营战略和人力资源战略来决定是外包还是内化的环境中，人才派遣和人才租赁就应运而生，它是一种全新的人力资源配置方式！
HRO用工模式 什么意思
HRO是指人力资源外包，它是一种人力资源服务产品，是企业根据需要将某一项或几项人力资源管理工作或职能外包出去，由比如人力资源顾问公司进行管理，以降低人力成本，实现效率最大化。内容包括：发放工资、代缴社保金、档案管理、人力资源规划、薪资调查及方案设计等方面。HRO用工模式即是人力资源外包编制，它是企业灵活用工最常见的形式，专家认为其应当涵盖整个HRO、福利产品、招聘服务、咨询服务、财务服务、行业租赁解决方案多方面的流程管理，从而帮助企业从繁杂的人事管理业务中解脱出来，全身心投入到企业经营和市场等核心工作中。
“rho”是什么意思？
“rho”的不同含义：1、n.希腊字母表中第十七个字母（译写为r,与送气符写在一起时译写为rh），symbol密度的符号，读音：［r??］；2、RHO(曲线饱满值),一般情况下:RHO 值越小,曲线就越平坦;RHO值越大,曲线就越饱满,RHO0.5时,曲线为双曲线；3、Rho=期权价格的变化/无风险利率的变化。Rho值可以定义为期权价格变化与无风险利率变化的比率。从数学上看，就是期权价格对于无风险利率的一阶导数。在实际交易中，我们通常取定期利率、国债收益率或Shibor来代替无风险利率。若投资期限较长或宏观经济短期出现剧烈变化导致利率和国债收益率等有明显变化时，投资者需要特别注意Rho值。Rho值的大小受到期时间、标的资产价格、波动率的影响。不管是看涨期权还是看跌期权，随着到期日的不断临近，Rho值逐渐趋向于0。不同之处在于，看涨期权Rho值非负，而看跌期权Rho值非正。这也表明离到期日越远，Rho的绝对值越大。对于Rho值的应用，投资者只需要在交易实值期权时加以关注就可以了。对于虚值期权，特别是深度虚值期权，Rho值的影响几乎可以忽略不计。同样，对于近月期权合约，我们也可以不用考虑Rho值风险，只需关注远月合约的Rho值变化。
.rho是什么样的文件格式
rho是声音文件，跑跑卡丁车里就可以看见的啊~~~
都玩过吧！
可以用各种的转换软件都行
如果你找不到，你可以用windows自带的Movie Maker用波形输出的方式来录旁白，点击开始旁白，拥暴风影音打开RHO文件，播放完毕，点击停止旁白。
录制的是WAM格式的，但质量和原文件一样好。
然后再转换成MP3格式，这很简单，我就不用说了！
