XRD indicated that the replacement of the terephthalate anion by the polytungstate anion had little effect on the structure.

结果表明，经过同多钨酸根阴离子的交换以后，垂直于水滑石层板方向的平行层板方向的晶格参数值变小，平行层板方向的晶格参数值不变，(003)、(006)、(009)衍射峰处的层间距值比为3：2：1；交换过程没有改变水滑石的结构，水滑石原位生长在γ-Al2O3表面及内孔，比表面积由γ-Al2O3载体的219平方公尺/g增加到247平方公尺/g，孔径分布则由原来的2~11nm变化为3~4nm。

This paper discusses some application cases of the error propagation law by the examples of trigonometrical survey, and presents that not only sum function and numeral multipling function in which there is only one independent observed value but also more complex functions which are equal in mathematics are not opposite in the process of error propagation according to the error propagation law.

1引言本文以三角测量为例，对误差传播定律一些应用问题进行了讨论，指出当只有一个独立的观测值时，和函数与倍数函数运用误差传播定律不会出现悖论；如果在测量工作中有多余的直接观测值，就需用平差后的间接观测值按协方差传播律来计算，这样数学中相等的函数关系才能得到同样的函

The crucial procedure of contour detection for microscopic image of sprayed droplets and measurement of granularity is to segment droplets from background by producing binary images. The singular threshold is uneffective because the image is very different in illumination. In this paper, a fast maximum entropy image thresholding algorithm based on local gray feature is presented to exact sprayed droplets from background and preserve contours of droplets.

雾滴图像的颗粒提取与测量关键是分割出雾滴与背景，生成二值图像，由于雾滴图像光照不均匀，用单一阈值无法兼顾亮区与暗区，本文提出了一种基于局部灰度特性快速最大熵动态阈值选择算法分割出雾滴微粒并提取雾滴轮廓。

In infarction patients group,DTI can early detect some small infarction lesions in white matter. With the pathophysiological evolution of the disease, FA and ADCAV changes regularly. In hyper-acute stroke, FA of lesions have no consistent change, appreciably elevated or decreased. In acute, sub-acute and chronic stages of cerebral infarction, FA of lesions unrecovered declined.

在脑梗死患组DTI能早期发现较小的白质内梗死灶，脑梗死后脑组织FA值、ADCAV值随病理生理演变呈一定规律性变化，病侧FA值在超急性期较对侧无一致性变化，可轻度升高或者轻度降低，随后(急性期、亚急性期、慢性期)呈不可复性减低趋势。

The oil yield was 28.35% under the optimal conditions. The characters of the oil were: refractive index 1.4681, acid value 9.65 mgKOH/g, iodine value 66.74 g/100 g, peroxide value 14.56 mmol/kg, unsaponifiable matters 1.93%, moisture and volatile matters 0.28%.

最佳条件下超临界CO2萃取的五叶瓜藤种子油的收率为28.35%；油的理化指标为：折光率1.4681、酸值 9.65 mg/g、碘值 66.74/100g、过氧化值14.56 mmol/kg、不皂化物1.93%、水分及挥发物0.28%。

Our experimental results shown that threshold voltage related hot only with the number of hecical turns ,hut a boundary-induced contraction or dilatation of the pitch also has a strong influence on it, at each regin, belong to a fixed n,the threshold voltage increases as the contraction of the pitch and the thieshold volage decreases as the dilatation of the pitch.

实验结果表明：阀值电压不仅与螺距数有关，而且与边界条件引起的螺距收缩和伸展有关，在螺距数不变的情况下，螺距的收缩使阀值电压提高，而螺距的伸展使阀值电压减小。

By way of parenthesis, In One-Point Input Method the relation is studied between the response and the correlative coefficient of horizontal and vertical earthquake wave.

提出了基于动剪应力极值的土体损伤值计算方法。以往计算土体在不规则的动剪应力作用下的损伤值根据的是动剪应力的峰值，在时域内多点输入分析中，由于差动力的的存在，使得时程后段动剪应力不穿零而在一侧做幅度不大的波动，基于峰值的损伤值计算特别过高地估计了这段剪应力的破坏作用，过高的程度还随延时增加而增加。

Instead of testing whether $a is equal to five, you've made $a equal to five and clobbered its old value.

这是把5赋值给了变量$a，抹掉它原来的值，而不是判断变量$a的值是否等于5。

Instead of a value, a function is provided, that computes the value.

不提供值，而是提供一个函数，由这个函数计算的值作为属性值。

As the same section is concerned, near the bottom the maximum value of frequency appear within 1mm of bubble size, towards the water face this value tend to decrease, yet the corresponding size turns to increase; in the same time, the frequency is concentrated near the bottom and deconcentrated near the water face; under the experiment condition, the maximum frequency of the total section approximately appear at 0.5mm size; mean bubble size access 0 at bottom and increase acceleratively towards water face where tend to be infinite; total number increase during developing of aeration, and become steady when reach wholly developed area; on the same section, the total number in unit time tend to increase at first and decrease then, along the water depth.

对于同一断面，靠近槽底的测点气泡个数分布最大值出现在气泡尺寸小于1mm的范围内，朝水面方向各测点气泡个数分布最大值呈减小趋势，而其对应尺寸则呈现变大趋势；在靠近槽底，个数分布表现得比较集中，而在水面附近气泡个数分布曲线表现得低而平缓；实验条件下，整个断面上的气泡个数分布的最大值大体上出现在尺寸为0.5mm的地方；气泡平均尺寸在槽底处接近于0而朝水面方向迅速增大，且越接近掺气水流的水面，增加速度越快，最终趋于无穷大；气泡总数在掺气发展区内是沿程增加的，当掺气水流发展到一定程度后气泡总数就基本保持不变了；在同一断面上，各测点单位时间内的气泡总数随高度呈现出先增加后减小的趋势。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
