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。

It is demonstrated that, in one aspect, in-situ zeolite has more effective catalytic capability based on unit active site, in another aspect, it has excellent ring-open activity as so called in-situ type hydrocracking catalyst can produce tail oil with generally 2-3 unit lower than traditional hydrocracking catalyst on BMCI index.

实验结果表明，原位分子筛材料不仅表现了具有更高本征催化效率的特点，而且突出表现了优异的开环裂解性能，所涉及的所谓原位型加氢裂化催化剂能获得比常规催化剂低2～3个单位的低BMCI值尾油。

Background: New studies showed that changes in the balance between haemostatic and antithrombotic processes, including a prethrombotic state might contribute to the development of atherosclerotic lesions which occured in hypertensive vascular complications. This may be one of the causes that satisfactory blood pressure reduction with antihypertensive drugs does not lead to an equal reduction in heart attacks and strokes. With the development of traditional presentation of blood coagulation, the role of tissue factor pathway has been emphasized.

Back in the 1950's, at the Common Cold Research Unit in England, then-director Christopher Andrewes, M.D., made volunteers stand nearly naked in frigid meat lockers and drafty gyms wearing little but wet socks for hours on end, and in no experiment did those who got chilled catch more colds, or worse colds, than people who spent the same amount of time happily ensconced in warm cozy rooms.
