负重变化率

Chinese to English Science Other
产品正面朝下置放于一平整玻璃上，再放上一块玻璃。测量平板玻璃下表面至桌面的高度。然后在玻璃中心放上X公斤法码，一分钟内再次测量上述高度。
用负重前所测高度与负重后所测高度的差值，除以负重前所测高度的百分比，既为负重变化率。

ysun Feb 23, 2009:
Re: “ratio of change” and “rate of change” 我认为 "ratio of change” 和 "rate of change” 都不大合适，因为 "ratio of change” 是指 "change/change” 而不是 "change/(original height)”，而 "rate of change” 则通常是指 "change/time”。
Adsion Liu Feb 22, 2009:
公式：按照我们国人的习惯，公式应该表达为...X100%
定义：翻译时尽量尊重原文作者的意图，尽量在定义名称和解释说明之间避免用同一个词
谨此。
karcsy Feb 22, 2009:
the formula W=(H1-H2)/H1x100 is correct, the 100 is aimed at converting the answer from decimal form to whole number (integer).
e.g. 0.25 == 25%
Joyce Curran (asker) Feb 22, 2009:
再次道歉， 我怎么认为你们俩都是正确的，而且都在说明同一道理，或许是我给的信息不全面。在这里，确实有这么一个公式：W=(H1-H2)/H1x100.
我不过是用叙述的方式来解释这个公式，其中H2为负重后高度，H1为负重前高度。
在此公式里，我们并没有发现百分率，但是后面的解释里，给予了百分率。
此解释说明： W为试样的负重变化率，百分数(%)。
就是这个解释让我直接释义为百分率。
但是我觉得公式错了，应该是100%，并非100。
Joyce Curran (asker) Feb 22, 2009:
这是我最空闲的一个周末？ 好几天了，我都没过问工作的事，试图给自己放几天假(猴儿们放假)，就离开电脑远远的。

首先，非常非常感谢Adsion， karcsy和Yueyin 的帮助！彼此之间的争论我还没有仔细去看，请再度给我一点时间，今天晚上一定参加讨论。

我一直都是幸运的，有你们如此无私的帮助！请原谅我给自己放的假！
Adsion Liu Feb 22, 2009:
Formula? The only thing I wanna say is: this is not a formula, but a definition, comprised of the description and the explanation. That's just what a context means...
Adsion Liu Feb 22, 2009:
How do you think, in your detailed context, Joyce?
Adsion Liu Feb 22, 2009:
Ysun's reference seems handsome to me...I have only tried to describe more exactly this definition (the name I mean), though I insist that percentage should be avoided in the description, as we should naturally put a "percentage" into the explanation...
karcsy Feb 21, 2009:
apllication of the sentence into formula. Keeping or not keeping the 百分比 in the Chinese text is not important, you should base it more on the formula by w.c it derived its computation. It is what it is. Percentage change computation is widely used, in this case, taking the height before loading (v1) subtracting it from the height after loading (V2) then dividing the difference by V1, the quotient is the Percentage change in load bearing capacity (负重变化率). This is not change rate, rate is expressed in distance over time. 用负重前所测高度与负重后所测高度的差值，除以负重前所测高度的百分比，既为负重变化率。 & the formula both cancel out the units and end up expressing the quotient in %.
Adsion Liu Feb 20, 2009:
Understanding You all make sense, Karcsy, however the definition in Chinese is 用负重前所测高度与负重后所测高度的差值，除以负重前所测高度的百分比, it's in fact about a percentage or ratio, the description of the definition should not only dwell at percentage, but alternatively ratio while keep the word "percentage" in the explanation. Thus:用负重前所测高度与负重后所测高度的差值，除以负重前所测高度的百分比，既为负重变化率=Take the difference (value) between the heights/altitudes measured before and after loading, and divide by the height measured before loading, we get a percentage, thus is the change rate of change due to/upon loading.
karcsy Feb 20, 2009:
correction 负重前所测高度 = V1 ; 负重后所测高度 = V2; v2-v1 is 差值; 差值/V1 is percentage change (answer is absolute - meaning always + number)
karcsy Feb 20, 2009:
further explanation applying the formula stated above into the formula in http://en.wikipedia.org/wiki/Percent_change, 负重前所测高度 is V1 & 负重后所测高度的差值 is V2.

A percentage change is a way to express a change in a variable. It represents the relative change between the old value and the new one.

用///负重前所测高度与负重后所测高度的差值///除以负重前所测高度///的百分比///既为负重变化率。

e.g. 负重前所测高度 = 5 cm
负重后所测高度 = 2 cm

(5cm - 2 cm)/ 5 cm X 100% = 60%

the cm unit of measurement will be cancelled out.

If 变化率 rate of change accdg to Adsion Liu is correct, rate is expressed in distance over time, e.g. km/hr (KPH), meter per second, etc. (not suitable to the above formula)

(2) percentage change due to load

neutral ILT : percentage change is plausibly OK, though it's not the "percentage" who changes neither change "OF LOAD", since the "变化率" is not actually about load, but about the ratio, rate or percentage of 负重前所测高度与负重后所测高度的差值/负重前所测高度的百分比...

variance ratio/change rate upon load(ing)

用负重前所测高度与负重后所测高度的差值，除以负重前所测高度的百分比，既为负重变化率。

here: 负重变化率=因负重而产/发生的变化比率
thus: 负重变化率=variance ratio/change rate upon load(ing), or due to load(ing) for the second part of expression; or briefer, upon-load variance ratio, etc.

percentage change sounds much nicer:-)
Thanks for karcsy's information, but I insist that, variance/change ratio/rate matches better this context... more accurate, height/distance (between xxx and xxx) variance/change ration

Reference:

"Percentage change under load" should be fine.

Deformation Under Load

Measure of the ability of rigid plastics to withstand permanent deformation and the ability of nonrigid plastics to return to original shape after deformation. Standard test methods for determining both types of deformation under load are given in ASTM D-621. For rigid plastics, deformation (which can be flow or flow and shrinkage) is re-ported as % change in height of specimen after 24 hours under a specified load. For nonrigid plastics, results are reported as % change in height after 3 hours under load and Recovery in the 1-1/2 hour period following removal of the load. Recovery is % increase in height calculated on basis of original height.

You can use "percentage change in height of specimen under load", if you want to avoid any possible misunderstanding.
