Get ready for a new kind of machine at yourlocal gym: one that doesn't involvehuffing andpuffing as you burn off calories. Instead, all you have to do isstand still for 30 seconds while the machine measures your body fat. It couldthen tell you exactly where you could do with losing a few pounds and evenadvise you on exercises for your problemareas. If the body fat scanner turns out to be accurate enough, its makershope it could one day help doctors spot disease.

为你们当地健身房里的一种新机器做好准备：当你运动燃烧脂肪时，这种机器不会让你气喘嘘嘘，【注1】你所要做的就是静站30秒，这时这种机器会测量你身体的脂肪。然后，它会确切的告诉你哪个部位应该减掉几磅，甚至为你提出合适的运动方式【注2】。如果身体的脂肪扫描足够的精确，制造者希望有一天这种机器可见帮助医生诊断疾病。

【注1】意见同前帖子，这种机器只是用来检测脂肪的沉积，不是帮助锻炼的，所以大意应该是：“但它不是你在燃烧卡路里而气喘吁吁时使用的”。

【注2】for yourproblem areas没有翻译出来。



The scanner works by simultaneouslybuilding up an accurate 3D image of the body, while measuring the body's effecton an electromagnetic field. Combiningthe two measurements allows the researchers to work out the distribution of fatand water within. Neither method is new on its own, says Henri Tapp, at theInstitute of Food Research in Norwich in the UK. "The smart thing is thatwe've put them in one machine."

当这种扫描仪测量人体对电磁场的反应时，它同时还能对身体进行精确的三维成像。运用这两种测量方法【注3】，研究者可以算出体内脂肪和水的分布。Henri Tapp在英国的诺维奇食品研究学院【注4】指出：任何方法本身并不是新生的，最明智的是我们把它们放在了一个机器中。【注5】



【注3】Combining还是强调两者的“结合”，直接译成“结合”。

【注4】at the Institute of Food Research in Norwich in the UK是补充说明Henri Tapp是谁，不是做状语，翻译“英国的诺维奇食品研究学院的Henri Tapp”。

【注5】new翻译“新的”，smart“巧妙的”。

And it's not just for gym users. The bodyfat scanner could be used to study fat deposition aschildren develop, whilepatients recover from injury, or during pregnancy, And since it uses radiowaves rather than X-rays, Tapp's device is safe to use repeatedly.

这种机器并不只是为了体育运动者【注6】。这种身体脂肪扫描仪可以被用来研究脂肪的堆积方式，就像小孩的成长过程，当病人从受伤恢复或怀孕中的孕妇。【注7】由于它采用的是无线电波而不是X射线，Tapp的设计当重复运用时也是安全的。

【注6】gym users“健身房人员”、“健身房用户”。

【注7】这句意思理解有所偏差，aschildren develop, while patients recover from injury, or during pregnancy,是三个并列关系，说明在哪三种情况下还可以用这个扫描仪。

“还能用于研究儿童发育、病人从损伤恢复以及怀孕过程中的脂肪沉积的检测”。



Body shape is known to be a risk indicatorfor heart disease and diabetes. So accurately quantifying fat distributioncould help doctors suggest preventive measures to patients before problemsarise. At the moment, doctors estimate fat content from knowing body volume andwater content. To a good approximation, says Tapp, anything that isn't fat iswater. The amount of water in the body is often measured by giving the subjecta drink of water that contains a radioactive tracer. The level of tracer in thepatient's urine after three hours reveals the total water volume.

体形可以看作是心脏病和糖尿病的危险暗示【注8】。所以精确的量化脂肪分布将帮助医生采取措施阻止疾病的发生【注9】。同时，医生可以从体形上来评估脂肪和水的含量【注10】。Tapp认为任何事物不是水就是脂肪【注11】。身体里水的总量的测量通常是通过给受试者服用一杯含有放射性的示踪剂的水。三小时后，受试者小便中示踪剂的水平就揭示了水的体积。【注12】

【注8】risk indicator危险因素

【注9】不是医生直接采取措施阻止疾病发生,而是“能帮助医生在问题发生前对病人提出预防性措施的建议”。

【注10】“目前，医生可以通过了解身体容积和含水量来估算脂肪含量。”

【注11】这里的“任何事物”扩大了原文意思。

【注12】reveal不一定要翻译成“揭示”，“3小时后在病人尿液中测得的标记物水平就可以测算中身体中总的含水量”

To find out a body's volume, subjects areweighed while totally submerged in water, and this is subtracted from their normal weight to give the weight of waterdisplaced, and hence the subject's volume. But it is scarcely practical forseriously ill people.

为了计算出人的体积，受试者在完全浸入水中后称重，得到的数字减去受试者自身的体重就得到了水的重量【注13】，因此也就算出了受试者的体积。但是这种方法对病重的人无法操作。【注14】

【注13】理解有误，应该是“真实体重减去在水中的体重”

【注14】seriously ill people. “重病患者”

There are other ways to directly measurebody fat, such as passing aminuscule current between the wrists and feet. The overall fat content can thenbe estimated from the body's resistance.But this method doesn't take body shape into account -- so a subject withparticularly skinny legs might register a higher fat content than the truevalue. That is because skinny legs -- with a lower cross-sectional area -- willpresent higher resistance to current. So the machine thinks the water contentof the body is lower -- rating the subject as fatter. Also, the system can onlygive an overall measurement of fat

还有一些其它的方法来直接测量身体的脂肪，比如在腕关节和足之间传递一种微小的电流。【注15】脂肪的含量可以通过人体的承受能力【注16】来估算。但是这种方法并不把体形考虑在内，因此当拥有纤细的腿的受试者算出的脂肪含量就可能比真正的体重【注17】要高。这是因为纤细的腿会对电流产生更强的耐受力。因此，这种机器认为人体中水容量比脂肪低。【注18】并且，这种系统只能全面的测量脂肪组织。【注19】

【注15】passing翻译“传递”不妥，不如“接通，连接”。

【注16】resistance 电阻.

【注17】不是脂肪含量和体重对比，“脂肪含量将可能比真实值高”。

【注18】rating the subject as fatter没有翻译出来。

【注19】“这个系统仅能算出给出体内脂肪的总量”

Tapp's method uses similar calculations,but is more sophisticated because it tells you where you are piling on thepounds.

Tapp的方法用了相似的计算，但又更加的复杂、精细，因为它还告诉你哪里在堆积脂肪。

在你健身房里面准备好一台新机器，当你燃烧你的卡路里它不需要你用力呼吸，你仅需静候30秒等待机器测量你的身体脂肪【注1】。它可以精确告诉你哪里可以通过锻炼减掉几磅，甚至建议你锻炼你的问题区域【注2】。如果身体脂肪扫描仪足够准确，它的制造者希望有一天它可以帮助医生发现病变。
注1：不是“你”的健身房；后半句见前帖。
注2：应该是“为你的问题区域做一些锻炼”。

The scanner works by simultaneously building up an accurate 3D image of the body, while measuring the body's effect on an electromagnetic field. Combining the two measurements allows the researchers to work out the distribution of fat and water within. Neither method is new on its own, says Henri Tapp, at the Institute of Food Research in Norwich in the UK. "The smart thing is that we've put them in one machine."
该扫描仪在测量人体的电磁场的同时建立身体准确的三维图像，结合两者研究人员可以算出体内水和脂肪的分布【注3】。没有一种方法是新的，英国 Norwich食物研究所的 Henri Tapp说 “我们把它们弄在一台机器里面是很聪明的做法”【注4】

注3：应该是“测量人体对电磁场的影响”。
注4：这句话用直译不太好，可译成“这两种方法都不是新的”；句末缺少句号。

And it's not just for gym users. The body fat scanner could be used to study fat deposition aschildren develop, while patients recover from injury, or during pregnancy, And since it uses radio waves rather than X-rays, Tapp's device is safe to use repeatedly.
它不仅对健身房用户【注5】。儿童的发展期身体脂肪的扫描仪可用于研究脂肪沉积，当患者损伤恢复或怀孕期间【注6】，因为它使用无线电波而不是X射线，Tapp的机器可以安全地重复使用。

注5：不是完整句子，未体现原文含义。
注6：这句话整个理解有误，可参考其他站友的译文。

Body shape is known to be a risk indicator for heart disease and diabetes. So accurately quantifying fat distribution could help doctors suggest preventive measures to patients before problems arise. At the moment, doctors estimate fat content from knowing body volume and water content. To a good approximation, says Tapp, anything that isn't fat is water. The amount of water in the body is often measured by giving the subject a drink of water that contains a radioactive tracer. The level of tracer in the patient's urine after three hours reveals the total water volume.
众所周知，体型是心脏病和糖尿病的危险因素。所以准确的量化脂肪分布可以帮助医生在患者出现问题之前做出预防措施【注7】。目前医生通过身体体积和水含量估算出脂肪含量。Tapp指出，初略的估计就是不是脂肪的东西就是水【注8】。通常水含量的测定是给受试者喝含有放射示踪剂的水【注9】。三小时后受试者尿液里示踪剂的水平可以显示水总含量【注10】。

注7：“地”。
注8：理解有误，参见前帖。
注9：可改成“通常，测量水含量的方法是让”或“测量水含量的常用方法是让”；根据汉语的语义看，这句话后面应该是逗号。
注10：用“显示”有些过于肯定和直接，可以改成“反映”。

To find out a body's volume, subjects are weighed while totally submerged in water, and this is subtracted from their normal weight to give the weight of water displaced, and hence the subject's volume. But it is scarcely practical for seriously ill people.
为了测量一个人的体积，受试者 浸入水中，通过总的体积减去水的体积就可以得出受试者的体积【注11】。但这种方法对于重病患者几乎没有实用性。
注11：理解有误，见前帖。

There are other ways to directly measure body fat, such as passing a minuscule current between the wrists and feet. The overall fat content can then be estimated from the body's resistance. But this method doesn't take body shape into account -- so a subject with particularly skinny legs might register a higher fat content than the true value. That is because skinny legs -- with a lower cross-sectional area -- will present higher resistance to current. So the machine thinks the water content of the body is lower -- rating the subject as fatter. Also, the system can only give an overall measurement of fat.
还有其他方法可以直接测量身体脂肪，比如通过手腕和脚的一个微小的电流。通过身体的电阻可以估计出总的脂肪含量【注12】。但这种方法没有考虑到体型。因此腿特别瘦的受试者得出的脂肪含量可能比实际要高【注13】。这是因为瘦的腿横截面小，电阻可能更高【注14】。据此机器就认为身体水含量更少，因而判定受试者更胖。此外该系统仅能给予总体脂肪含量【注15】。

注12：这句话最好用意译，直译成汉语不容易理解。
注13：“测算出”？
注14：“的”和“可能”应该删掉。
注15：少译了measurement。

Tapp's method uses similar calculations, but is more sophisticated because it tells you where you are piling on the pounds.
Tapp的计算方法与此类似，但它更为复杂因为它可以告诉你哪里长胖了【注16】。

注16：
“复杂”后加个逗号？
