    關(guān)于大家期待已久的大便的味道的問題。 我為什么可以知道大便是什么味道呢?當(dāng)然不是因?yàn)槲覈L過大便。雖然我號(hào)稱是一個(gè)重口味的人,但是真的以身嘗糞這種事情是做不出來的。那么我是怎么知道大便應(yīng)該是什么味道呢? 這個(gè)么,有古籍的支持。明代李時(shí)珍在《本草綱目》中說“糞清”:“近城市人以空罌塞口,納糞中,積年得汁,甚黑而苦,名為黃龍湯,療瘟病垂死者皆瘥?!边@個(gè)藥是催吐的。所以《本草綱目》中對(duì)人屎的主要描述是苦,而且催吐。但是《本草綱目》本身就是一本很不靠譜的書,固然催吐這個(gè)功效毫無疑問是對(duì)的,但是是不是發(fā)苦也吃不準(zhǔn)。另外就是史書上對(duì)越王勾踐嘗夫差屎的典故,故事的描述是說屎“味酸而苦”,也就是說,不僅有苦味,還有酸味。但是勾踐的故事也不可盡信,一來年代久遠(yuǎn),二來勾踐本來就是滿嘴跑火車哄夫差的,是不是真的這個(gè)味道也不得而知。 古籍不可盡信,難道真的不得不用口嘗的方法來判斷大便的味道嗎?圖森破,奶已無!當(dāng)然我們要肯定醫(yī)學(xué)工作者為科學(xué)獻(xiàn)身的精神,但是為了判斷大便的味道而親自嘗糞這種無聊的事情就沒有必要了。畢竟我們有科學(xué),直接通過研究糞便的成分就能大致猜測(cè)糞便的味道了。 首先大便肯定是咸的,雖然尿液是人體排出多余電解質(zhì)的主要手段,但是腸道也能起到排除多余鈉、鉀離子的作用。尤其是當(dāng)你腹瀉的時(shí)候,大量富含電解質(zhì)的液體通過腸壁分泌,于糞便混合而排泄出來,勢(shì)必是咸味的。 然后前面說了,吃大便確實(shí)有催吐的作用。主要是大便中含有大量胺類物質(zhì),比如尸胺、腐胺,還有吲哚。聽名字就知道這些東西不會(huì)好吃,因?yàn)檫@些也是腐敗的食物、尸體中富含的氣味物質(zhì)。具體的味道可能并不明顯,類似腐敗的肉類或魚類,但是氣味勢(shì)必非常的腐臭難聞。雖說這些物質(zhì)主要是發(fā)揮氣味而非口味的作用,但是人類的食欲主要是由氣味調(diào)動(dòng),因此在品鑒大便時(shí),此類胺類化合物的影響也不可不察。 當(dāng)然大便也有可能有酸味。這完全要拜腸道菌群所賜。人進(jìn)食的食物當(dāng)中的碳水化合物、纖維素等物質(zhì)會(huì)有少量進(jìn)入腸道,在腸道菌群的作用下會(huì)分解為有機(jī)酸類(比如醋酸、乳酸等),這些酸味物質(zhì)混合在大便中就會(huì)使大便成為酸味。不過這通常出現(xiàn)在飲食中素食比例較多的人當(dāng)中。如果是愛吃肉的人,大便中的胺類會(huì)比較多,味道會(huì)更惡臭一些。 大便中的苦味可能來源于膽汁。我們知道膽汁是將大便染成黃色的主要原因,同樣膽汁也是一種味道非??嗟奈镔|(zhì)。因此Z終拍出體外的大便由于含有膽汁的緣故,勢(shì)必是帶有苦味的。 另外關(guān)于大便中一定不會(huì)有的味道。一個(gè)是甜味,由于糖類對(duì)人體來說是極為珍貴的能量來源,因此人吃進(jìn)肚內(nèi)的糖類很少能夠通過胃腸道層層關(guān)卡的剝削,進(jìn)入大腸,參與糞便的組成。即便有少量難以消化的纖維素、多聚糖等漏網(wǎng)之魚,也早被腸道菌群瓜分一空,所以正常人的糞便應(yīng)該是不會(huì)有甜味的。另一個(gè)味道是脂肪的香甜味,因?yàn)槲改c道對(duì)脂肪的吸收效率幾乎為,只有嚴(yán)重病態(tài)的情況下才會(huì)在糞便中出現(xiàn)脂肪,即我們所稱的脂肪瀉。 所以大便的味道一定不會(huì)很好,在食物中Z容易引起我們食欲的兩種物質(zhì):糖和脂肪,在大便中都完全沒有。而大便卻富含另一些令人作嘔的物質(zhì),如尸胺、腐胺等。所以大便的味道應(yīng)該是又苦又酸又有一股腐爛的惡臭味,基本屬于難以下咽。 特殊口味的大便: 我們知道吃完辣椒會(huì)辣菊花,由于人體內(nèi)缺乏分解消化辣椒素的酶類,所以辣椒素從嘴里吃進(jìn)去,是原樣從菊花排出來的。所以如果是吃完辣以后排出來的辣菊花大便,應(yīng)該也是辣的。又苦又酸又惡臭還帶辣味的大便……很難想象是什么口感呢。 常逛果殼的網(wǎng)友一定知道“see you tomorrow”的典故,一些富含木質(zhì)素的食物,比如玉米、金針菇之類的,吃完以后會(huì)原樣拉出來。所以如果是這類大便的話,里面除了大便主菜,還有金針菇小點(diǎn)心也說不定…… 其實(shí)人體不能消化的食物還蠻多的??煽煞垡彩侨穗y以消化的物質(zhì),所以很多人吃完巧克力以后會(huì)拉黑粑粑,不是傳說中的黑便,而是可可粉把大便染成黑色。所以是巧克力味大便…… 當(dāng)然還有其他很多各種病態(tài)大便,不過不建議大家嘗試就是了(任何人類大便都不能吃啊喂?。?,不過消化道出血引起的黑便還是會(huì)有其獨(dú)特風(fēng)味的,主要的風(fēng)味應(yīng)該是黑便中經(jīng)腸道氧化而成的三價(jià)鐵離子提供鐵銹味。。。 http://www.guokr.com/blog/263822/

LabVIEWTM(LaboratoryVirtualInstrumentEngineeringWorkbench)isapowerfulinstrumentationandanalysisprogramminglanguageforPCsrunningMicrosoftWindows,SunSPARCstations,AppleMaci... LabVIEWTM (Laboratory Virtual Instrument Engineering Workbench) is a powerful instrumentation and analysis programming language for PCs running Microsoft Windows, Sun SPARCstations, Apple Macintosh computers, Concurrent PowerMax, and HP-UX workstations. LabVIEW departs from the sequential nature of traditional programming languages and features a graphical programming environment and all the tools needed for data acquisition, analysis, and presentation. With this graphical programming language, called “G,” you can program in a block diagram notation, the natural design notation of scientists and engineers. After you create a block diagram program, LabVIEW compiles it into machine code. LabVIEW integrates data acquisition, analysis, and presentation in one system. For acquiring data and controlling instruments, LabVIEW supports RS-232/422, IEEE 488 (GPIB), and VXI, including Virtual Instrument Software Architecture (VISA) functions, as well as plug-in data acquisition (DAQ) boards. An instrument library with drivers for hundreds of instruments simplifies instrument control applications. For analyzing data, the extensive Analysis library contains functions for signal generation, signal processing, filters, windows, statistics, regression, linear algebra, and array arithmetic. Because LabVIEW is graphical in nature, it is inherently a data presentation package. LabVIEW can generate charts, graphs, and customized, user-defined graphics. 盡量翻的好一點(diǎn),謝謝 能不能對(duì)GOOGLE自動(dòng)翻譯過的稍加修改下 展開

Since its advent in the early 1970s the logic analyser has become arguably the most important single piece of test equipment in the digital designer’s armoury. It is now a far more versatile instrument than its early predecessors, still offering a complete solution to today’s ever more complex digital design and measurement challenges. As with most modern test equipment, the ongoing development of logic analysers has been fuelled by continual improvements in microprocessor technology, allowing cost-effective implementation of advanced measurement techniques. This continual development has been driven, to a great extent, by the need to be able to debug complex microprocessor-based or highspeed state machine designs. As the inclusion of microprocessor or VLSl components into circuit design becomes more and more routine, the instrument manufacturer must maintain the logic analyser as a user-friendly, relatively-low-cost solution to modern digital design and test problems. In addition, however, as these components increase in both complexity and performance, the instrument manufacturer must be able to support state-of-the-art measurement techniques, while still offering the digital design engineer the same depth of general-purpose circuit analysis.Clearly, as design complexity increases, an increasing volume of measurement data must be represented and manipulated in such a way that it can be quickly and easily interpreted by the engineer. The basic logic analyser provides a means of monitoring software execution, digital hardware operation and, more importantly to many, the interaction between the two. Being the only instrument that can comprehensively bridge this notional divide between hardware and software, the logic analyser is often given the role of arbitrator in the search for that elusive system bug. 展開
