基圆

A neat solution of the quadrature problem can be achieved with the spiral of Archimedes.

用阿基米德螺线能成功地解决化圆为方的问题，方法很简单。

Japan's main Samsung, Japan Bando, Germany than Austria, the United States Gates, Italy SAMPLA, Netherlands DERCO, varieties are: conveyor belt, using Teflon oven conveyor belt, V-belt, timing belts, speed zone, on-chip baseband, with a round steel and steel deduction and the deduction of such mechanical and electrical spare parts, the operating company, I really merged with the world.

主要有日本三星、日本阪东、德国奥比、美国盖茨、意大利SAMPLA、荷兰DERCO等，品种有：输送带、烘箱用铁氟龙输送带、三角带、同步带、变速带、片基带、圆带以及钢扣和钢扣机之类机电零配件，我公司的经营真正做到了与世界并轨。

Dynamic changes of three protective enzymes activity and MDA content of Catalpa 'Jinsi' and C.'Yuanjichangguo' during softwood cutting time were studied. And the relations between its dynamic changes and rooting rate were analyzed and discussed.

以金丝楸和圆基长果楸的嫩枝为材料，研究了ABT处理下扦插生根过程中3种保护酶活性和丙二醛含量的动态变化，分析了其变化规律与生根的关系。

The diffraction theory of Kirchhoff is applied to the four-pinhole aperture diffraction screens, the intensity, the zero-contour of the real and imaginary parts of complex amplitude and the phase distribution in deep Fresnel diffraction region are simulated, and it is found that the bright spots in interference field show central symmetry distribution. When the observation plane close to the diffraction screen, the zero-value points of light intensity can form line segment, on which the eccentricities of the light intensity isoline are close or equal to 1, the intensity changes very fast on both sides of the zero-line of light intensity.

利用基尔霍夫衍射理论计算了四圆孔径衍射屏在菲涅尔深区形成的的干涉光场的强度、零值线和相位的分布，发现干涉光场亮斑关于中心呈对称分布，在距离衍射屏较近的观察面上，光强值为的零点组成光强零值线段，该线段上光强等值线的离心率都接近或等于1，其两侧的光强值变化非常剧烈。

The circular disk is somewhat easier to machine and to load than the tensile 3 specimen; moreover, if required, several calibration points can be obtained from a single load.

基於试片加工与负载的方便性，而且可以只从单一负载就可取得多点资料，所以圆盘试片受上下压力实验法是比较被推荐使用的方法。

Internal Grinder: ordinary type-based series, mainly used for grinding cylindrical and conical inner surface of the grinder.

Cylindrical Grinder: ordinary type-based series, mainly used for grinding cylindrical and conical outer surface of the grinder.

1外圆磨床：是普通型的基型系列，主要用于磨削圆柱形和圆锥形外表面的磨床。

Leaf blade crenate; obtuse or auriculate at base.

叶片具圆齿；钝的或耳形在基部。

Leaf blade ovate, margin serrate or deeply crenate, base not decurrent to petiole

叶片卵形，边缘有锯齿或具深圆齿，基部不下延至叶柄 55

During the incubation of purified α-synuclein with fructose or glucose, it was observed that the protein intrinsic fluorescence at 308 nm decreased while the fluorescence of glycated derivant at 447 nm increased.

将纯化后的α-synuclein分别与果糖和葡萄糖孵育，通过内源荧光、非酶糖基化衍生物特征荧光、圆二色光谱以及电子显微镜等技术进行检测发现：α-synuclein 与还原糖共同孵育后，308 nm内源荧光强度明显降低，同时在447 nm产生一个非酶糖基化衍生物特征荧光。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
