A Novel Method for Intrinsic Viscosity Determination of Polymer SolutionThere are many methods for molecular weight determination of polymers, among which viscometry is used most, it has been broad applied both in production and scientific research. This method is easy to operate with simple instruments and is applicable for broad-range molecular weight, additionally, it has high precision.

在许多情况下，常需要对同种类聚合物的特性粘度进行大量重复测定，如果都按此法操作，每个样品至少要测定3个以上不同浓度溶液的相对粘度，这是非常繁琐的，而且需时较长，尤其在所得样品量极少的情况下，就难以用此法求得高聚物溶液的，为此，人们找到了更快速的近似方法，即"一点法"。

It's called brown fat (as opposed to the more familiar white fat that hangs over belt buckles and swings from the backs of arms) and a series of papers published in the New England Journal of Medicine confirm for the first time that healthy adults have stores of this adipose tissue, which researchers hope to study further as a potential new weight loss treatment.

这种脂肪叫棕色脂肪(用以和悬挂在腰带扣上的白花花的脂肪以及后背和胳膊上的脂肪相区别。)新英格兰的医学杂志上发表的一系列论文也第一次证实健康的成年人体内都有这种动物脂肪组织，研究人员正对这种脂肪进行研究，希望能从中找到一种新的减肥方法。

Cavitation is the most distinct characteristic of the high-power low-frequency ultrasonic fields, and it is also regarded as the primary mechanism of ultrasonic cleaning. Nevertheless, the measurement question of the high-power low-frequency ultrasonic fields hasn't been resolved well, because of the incomplete cavitation theory and the complexity of cavitation fields. The universal acceptant standard measurement hasn't been found up to the present so that it is difficult to judge of the performance of ultrasonic cleaning machines scientifically.

大功率低频超声场最鲜明的特点就是空化，而空化也被认为是超声清洗的主要物理机制，但由于其理论研究尚不完善，加之空化声场的复杂性，使得至今大功率低频超声场的测量未得到很好的解决，尚未找到一种与清洗效果有确定关系的普遍适用的标准方法，使得在客观地评判清洗机优劣时很困难。

The algorithm smooths the gray histogram of the test image with Harr wavelet to remove the "pseudo valley", and fixes a range of the threshold according to the prior information in the standard image, and then finds out the valley of the histogram in the range and that is the threshold. The ex perimental results show that the preprocess algorithm is able to obtain a satisfactory threshold for the binarization of the test image.

该方法使用Harr小波对待测图像的灰度直方图进行平滑处理来消除其中的&伪谷值点&，再充分利用标准图像的先验信息来确定一个二值化分割阈值的大致范围，最后在这个范围内找到直方图的谷值，这即是所需的阈值。

Find the highest priority thread that is mapped to the kseg that this Thread is part of. Optionally heuristically try to improve cache locality by running a thread that may still be partially warm in the processor cache.

在KSEG中找到一个优先级最高的线程，把这个线程放在一个还有部分该线程的缓存仍然的没有被清除的处理器上，通过这种可选的试探性方法提高缓存的击中率。

We reasoned that the use of pleural-pressuremeasurements, despite the technical limitations to the accuracyof such measurements, would enable us to find a PEEP value thatcould maintain oxygenation while preventing lung injury dueto repeated alveolar collapse or overdistention.

尽管目前的技术使这种方法的准确性有限，我们论证了使用胸腔压力检测来测量PEEP的数值，可以使我们在预防由于肺泡反复塌陷和过度膨胀而引起的肺损伤中找到维持氧合的PEEP。

You better know when you're swingin' round the room Look's like magic's solely yours tonight But I don't feel like dancin' When the old Joanna plays My heart could take a chance But my two feet can't find a way You think that I could muster up a little soft, shoop devil sway But I don't feel like dancin' No sir, no dancin' today.

你知道更好当你的swingin ' 24室看的魔术一样的单纯，你今晚但我不喜欢歌舞'当旧扮演乔安娜我的心能有一个机会但是我的两个脚不能找到一种方法你以为我可以纠集起来有点软，贾拉勒塔拉巴尼魔鬼摇但我不喜欢歌舞'没有先生，没有歌舞的今天。

However, in electric field computation, the BEM has not much unfould and most of them are limited in the conventional BEM. In the flow field computation, although some achievements have been gained in solving the constant and uncompressible fluid flow by using BEM, but to the inconstant, compressible, nonlinear, transonic flow, such as the flow in the arc quenching chamber in SF6 high voltage circuit breaker, no any report has been published up to now for the reason that the basic solution of this kind of flow has not been found.

目前，在电场计算领域所开展的工作相对较少，而且仅限于传统边界元方法的应用；在计算流体力学领域，近年来虽然一些学者应用边界元法，在解决定常、不可压缩等问题进行了相当深入的研究，获得了若干研究成果，但是对于像SF_6高压断路器灭弧室中存在的非定常、可压缩、非线性、跨音速、具有复杂而且变边界的气流场由于至今尚未找到基本解，而未见研究工作的报道。

The unlifting pressure process in solid abrasive doublesides lapping has been studied through the mathmatics model established in this paper.

针对固着磨料研磨的特点，通过所建立的数学模型，对固着磨料双面研磨过程中压力的变化进行研究，并对研磨过程的压力实施进行优化，从而找到在研磨过程中最佳的施压方法，以达到对硅晶片、玻璃硬盘基片等进行高速精密和超精密加工的目的。

The UN Convention of the Sea ordains that the division of the sea area should be based on the international laws and in a peaceful way .

规定，海洋划界争端应在有关国际法的基础上，以和平的方式加以解决，中，日两国的海洋划界应该按照国际法的规定，找到适合两国情况的比较公平的原则和方法。
