骑车上班,你值得这么做? this morning, i rode my bike in to work (a distance of about 10 miles), and it felt great. it was the second time i’ve done that now — i also did it last week — and i hope to make it a more frequent thing. my goal is to get some exercise (i’m training for a triathlon) while also helping the environment and saving money on gas. with the gas prices rising so much in the last few years, it’s frustrating to not be able to do anything about it — but now i am. although it’s a bit scary riding a bike in the middle of traffic, i have to say it was a great experience. not only did i feel really good to get the exercise, but i had a great view of nature as i headed to work, and it was a lot more peaceful and relaxing than the regular commute by car. i hope to eventually build up my stamina so that i can ride my bike to and from work at least three or four times a week, or even five days a week, but for now i’m starting out slowly, as i’m new to cycling. tips for commuting by bike plan ahead. one of the reasons people don’t commute by bike, even if they have a bike, is that they don’t want to be sweaty. i’m lucky, as my work just installed a new shower, but before that i planned to use the shower of an office next door, or use the shower at a nearby gym (even becoming a member at a gym is cheaper than gas). you’ll also need soap and deodorant and a towel and other toiletries. then there’s the issue of how to get your clothes to work, which is my next tip. drop your clothes to work ahead of time. you could pack them in a backpack, to wear on your back, but it gets your back sweaty. you could also put it in a pannier and carry it on a rack, which is a good option, but you might not want your clothes wrinkly for some reason. the solution i’ve been using (and it’s not an original idea) is to bring my clothes to work the day before. this also saves some extra pounds that i have to carry on my bike, which is an issue for a beginner like me. you could even bring in clothes for the rest of the week. eventually, if i ride to work five days a week, i might have to drop a week’s worth of clothes sometime in the weekend. any ol’ bike will do. you don’t need a fancy racing bike or touring bike or anything to commute. if you’ve got an old mountain bike, which i do, that’s good enough. you don’t need to spend a lot of money on a bike and gear to get started. later, you can always spend more, a little at a time, but whatever you’ve got is good enough for now. have a spare tube and tools, and know how to change a tire. you never know if you’ll get a flat, and you don’t want to be stuck walking your bike for several miles. a patch kit is good, but it’s even easier if you just have a spare tube, a pump, and the right tools so that you can quickly change the punctured tube for a new one, and patch the old one later at home. be safe. this is a no brainer, but it is good to read up on tips on cycling safety before heading out into dangerous traffic. it’s a blast! cycling is a lot of fun, as i’ve discovered in recent weeks, and riding to work is much, much better than driving. try it. you’ll love it. 今天早晨,我骑车去上班(大约10英里的距离),感觉棒极了。这是我第二次这样做了(上周我也做过一次),我希望今后经常这样做。 我的目标是得到一些锻炼(我正在参加铁人三项的训练)的同时,也对环境有益并省下了花在汽油上的钱。随着过去几年汽油价格的大幅上涨,对此无能为力是非常令人沮丧的。但是现在我有办法了。 尽管骑车在各辆交通工具中穿梭是一件有点吓人的事,我还是认为这是一种很棒的经历。我不仅为得到了锻炼而感到高兴,而且在我去上班的路上还可以欣赏自然美景,这比开车上下班更为宁静和放松。我希望逐渐加强我的耐力,这样我就可以一周至少有三、四天骑车上下班,甚至一周五天。但是现在我还在慢慢起步,因为我还是骑车的菜鸟。 骑车上下班的忠告: 提前计划。人们即使有自行车也不骑车上下班的一个理由便是,他们不想满身大汗。我很幸运,因为我工作的地方刚刚安装了一个新的淋浴,但在那之前,我就计划使用隔壁办公室的淋浴或附近健身馆的淋浴(即使成为健身馆会员也比汽油便宜)。同时你会需要香皂、除臭剂、毛巾和其他化妆品。那接下来就是如何换上班服装的问题了。这正是下一条忠告的内容。 提前将衣服留在办公室。你当然可以将衣服装在背包中背着上班。但是这就会使你的后背出汗。你也可以将其放在篮子里,驼在车架上,这是一个好的选择。但你也许不希望你的衣服由于一些原因变得皱巴巴。我使用的方法(它并不是原创的主意)是提前一天将衣服放在办公室。这也减轻了骑车时的重量,对我这样的新手而言是一个问题。你甚至可以将下一周的衣服都提前带过去。如果最终我一周五天骑车上班的话,我也许会在周末将下一周的衣服都带过去。 任何自行车都行。你并不需要一辆昂贵奢华的赛车或旅行车或其他。如果你有一辆旧的山地车,像我一样,就足够好了。开始时,你不需要在自行车或传动装置上花费过多金钱。日后,你会花费更多的,一次一点,但是你从中收获的会物有所值。 携带备用车胎和工具,并知道如何换胎。你永远不知道你的车胎是否会瘪气,你肯定不希望推着车走上几英里。一个修补包是很好的,但如果你只有一个备用车胎,一个打气筒,以及正确的工具,事情会变得更简单,你可以快速将被刺穿的车胎换成新的,然后回到家再补胎。 注意安全。这是一个无需用脑的事,但仍然建议在骑车进入危险交通之前先读一下安全骑车的知识。 这是一次狂欢。骑车非常有乐趣,这是我近几周发现的。而且,骑车上班要比开车不知好多少倍。来尝试吧,你会喜欢的。 转摘自海词快乐英语,供朋友们分享查看更多
氩馏分高低调整的一句经典解决措施-何解? 内压缩流程一般也设置了一个氧气阀门,氧气阀门旁通到污氮气中的。 可以调整这个阀门。 内压缩没有氧气旁同污氮的流程,也可以通过氧气产量来改变下塔回流比!影响氩留份吧!查看更多

精馏塔的最佳工作状态如何衡量? 同意2楼的说法。还有一点衡量标准----进料量,每个精馏塔都有最大进料量也就是生产能力,当各清馏塔各塔液位均衡,不满塔,不堵塔,塔顶产品保证连续最大采出量(合格),一直加到不能加再的状态。越满负荷,各项消耗越低。即高产,又降耗。查看更多

GB150筒体厚度计算公式适用于设计压力小于等于35MPa是否 ...? gb150适用范围是有35mpa这么一个限制。像在sw6中,超过35mpa的输入会提示超出范围。但就计算公式本身而言,应该也是可以计算的,前提是在弹性范围内,不过这样貌似壁厚会比较大。高压容器我见得比较多的是多层包扎的,不过详细的设计过程不是太清楚,应该和中低压的设计大同小异吧。查看更多
