Base pads must be in line and flat within 1/64 so base will not rock.

所有显示的中心线(5处)必须在相应的直径中心的直径0.002的圆内。

The ratio of the circumference of a circle to its diameter is pi.

比例的圆周一圈，它的直径是有价证券投资。

It was wholly in the lower ice, but close against the upper, and was flattish, or perhaps slightly lenticular, with a rounded edge, a quarter of an inch deep by four inches in diameter; and I was surprised to find that directly under the bubble the ice was melted with great regularity in the form of a saucer reversed, to the height of five eighths of an inch in the middle, leaving a thin partition there between the water and the bubble, hardly an eighth of an inch thick; and in many places the small bubbles in this partition had burst out downward,and probably there was no ice at all under the largest bubbles,which were a foot in diameter.

在气泡之下和周围已经结了一层新的冰，所以气泡是在两片冰的中间；它全部是在下层中间的，却又贴近上层，扁平的，也许有点像扁豆形，圆边，深四分之一英寸，直径四英寸；我惊奇地发现，就在气泡的下面，冰溶化得很有规则，像一只倒置的茶托，在中央八分之五英寸的高度，水和气泡之间有着一个薄薄的分界线，薄得还不到一英寸的八分之一，在许多地方，这分界线中的小气泡向下爆裂，也许在最大的直径一英尺的气泡底下完全是没有冰的。

Therefore, the user in the time of order if you have special requirements, such as thin film to India or want Business card printing and membership card making function from 60 grams of India to 330 grams, can only be the diameter of the rollers and nano-imprint lithography gear pitch circle diameter of mutual relations.

所以，用户在订货时如果有不入格给求，比如给印超薄的薄膜或者但愿制卡和会员卡制息性能从60克印至330克，只能在压印滚筒的直径与齿轮节圆直径的彼此干系上怠工调动。

The allowable processing length of the wooden sticks is 60mm to 1800mm, the allowable diameter is 15mm to 120mm and the length and diameter can be customized according to the requirements of the customers. For instance, we can deal with the drilling, processing of the round wood, American-style screw thread and Italian-style screw thread to meet the different demands by the customers.

木柄类产品可加工的长度是60 MM-1800 MM ，可加工的直径是15 MM-120 MM，长度和直径都可以根据客户的要求定做，例如钻孔、加工圆头、美式螺纹、意大利式螺纹等，满足客户的众多需求。

By rotating the X-axis of the measurement coordinates, the straightness data of each generatrix are transformed into a unified 3D coordinate system whose Z-axis superposes the least square mean axis calculated with the data of the multiple generatrices. The computer simulations and experiments prove that the construction by rotating the abscissas can effectively eliminate the distortion of the constructed profile.

通过测量坐标系中X轴的旋转，将各条母线直线度偏差数据统一到同一个空间坐标系中，采用两端面圆的最小二乘轴心的连线作为零件轴线，消除了直接构造所带来的表面变形，并能进一步计算出被测内孔的直径、圆度和轴线直线度误差，使测量系统集成化和多功能化。

A diameter is a line that bisects a circle.

直径就是平分一个圆的直线。

The plasma arc generator comprises cathode, two anodes and insulating strip between two anodes, first anode is cylindrical hollow sleeve, the cylinder cathode is placed in the centre of said sleeve, and an annular fluid channel is formed between both the lower portion of first anode is equipped with a hole as fluid outlet, and second anode is a circular plate with central hole, between two anodes there is an insulating strip, the diameter of central hole of second anode is less than the diameter of lower hole of first anode.

本发明是一种串式多级压缩等离子弧发生器，由阴极、两阳极及阳极之间的绝缘片组成，第一阳极为圆柱形空心套管，圆柱体阴极处于该套管中心，并在两者之间形成环状流体通道，第一阳极下部是一个供流体出口的横截面为圆的孔，第二阳极是中心开孔的圆形板，两阳极之间有绝缘片，第二阳极中心孔的直径小于第一阳极下部孔的直径。

Observing through SEM and TEM, we could found that the diameter of zeolite particle is during 10~20nm, the diameter of straight chain diatomite is between 8μm and 20μm, and the diameter of discoid diatomite is between 15μm and 20μm. From the diagram of TGA and DGA, we could draw the conclusion that the adsorption capacity of diatomite could be increased by heating method under appropriate temperature. The results of FTIR analysis show that there are several libration between 1510 cm~(-1) and 1529 cm~(-1), and this result can sufficiently prove the adsorption of benzene hydrocarbons.

4对材料进行了表征，通过SEM和TEM可以观察到分子筛粒径大小在10～20nm之间，直链结构的硅藻土直径约为8～20μm，盘状硅藻土圆盘直径约为15～50μm；经过TGA和DGA证实了，对硅藻土进行适当温度的活化可以提高硅藻土的吸附效果；经过IR分析，可以发现在1510～1529cm~(-1)之间出现了多个振动峰，这证明了分子筛对苯系物的吸附效果。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
