We will in effect define x to be the set of rationals smaller than x .

我们把 x 定义为小于 x 的有理数集合。

"The idea behind Dedekind cuts is that a real number x can be named by giving an infinite set of rationals, namely all the rationals less than x .

Methods the data on x ray films、ct and mri of the 12 patients with fat embolism syndrome were ananlyzed retrospectively.results the chest x ray films showed diffuse shadow of the pulmones in 3 cases,multiple patchy in 4 cases ,little pleural effusion in 1 case ,the left 4 casses were normal .the chest ct showed patchy ground glass opacity and nodules in 12 cases, pleural effusion in 2 cases.

回顾分析12例脂肪栓塞患者的x片、ct、mri检查资料。结果：肺部x片示3例弥漫密度增高影，4例多发片影，1例少量胸腔积液，4例正常。ct示12例斑片状、磨玻璃、结节影，2例胸腔积液；脑部ct示2例示低密度影，6例正常；mri示8例t2wi均为高信号。

This allows Transformer-Printhead-enabled presses to print images up to 109 x 90 cm (43" x 36") on alternating printheads, adequate for oversize and all-over prints.

这使采用变形印花头的印花机可以在交替印花头上印刷面积达109 x 90公分（43英寸 x 36英寸）的图像，完全可以实现超大面积的全幅面印刷。

It is treated with six fields (Anterior, Posterior, four obliques) positioned 60° apart around the circumference of the patient, each dual field is made up of two component beams, pointing ±15° with respect to the horizontal. The nominal energy of electron beam produced by Mevatron Ⅻ is 3MeV, and the patient is treated at a distance of 3 meters. Using Capintec dosemeter and PS-033 electron beam chamber for measurement, one moniter unit of radiation is equivalent to 0.0127cGy. Measurement of electron energy by Kodak X-omat-V verification film inside the Rando phantom at 100 cm SSD was 3.70MeV, electron energy measured at 3 meters was 3.51MeV. X-ray contamination was measured as 9.5% per six dual fields.

此种方法分别使用六个双照野，由病人的前、后、左前、右前、左后、右后各间隔60度共六个方向照射，每一双照野由水平向上和向下15度照射；荣民总医院选择3MeV电子射束来治疗病人，治疗距离为3公尺，利用擬人假体及柯达X-omat-V验证片实验得电子射束初始能量从3.7Mev变为3.51MeV，六个双照野之X光污染共达9.5%，使用Capintec剂量表及PS-033型电子射束用游离腔测量六个双照野，每一监测单位相当於0.00127 cGy。
