Objective To study the injury of rat cardiomyocytes exposed to nonionizing radiation and its mechanism.

目的探讨非电离辐射对大鼠心肌细胞损伤效应及机制。

These are nonionizing EMF of much longer wavelength.

这些是非电离辐射，波长要长得多。

Due to ultrasound nonionizing radiation, harmless to human, and cheap to produce, ultrasound tomography technique has broadly applied to various fields such as biomedical engineering, geophysics, nondestructive evaluation and pattern recognition etc..

由于超声波具有无电离辐射、对人体无害、设备价格便宜等优点，这一技术广泛应用于生物医学工程、无损检测、地球物理、模式识别等领域。

We also discussed the signal characteristics of each kind of tumors.MRI has ben showing great advantage in evaluating the tumors of the spinal canal:nonionizing radiation. noninvasive, no bony artifacts, multiple planes imaging, there is no need to inject agents to the canal, and one image can demonstrate multiple lesions.

MRI在评价椎管肿瘤方面显示出世大的优越性：无电离辐射、无创伤性、无骨伪影、多平面成像、不需椎管内注入造影剂、多发病变一次成像，直接显示肿瘤信号及其与周围结构的关系，定位及定性准确率高。

Low dose radiation could significantly increase the immune function of tumor-bearing mice,and this stimulatory effect may be of some potential significance in tumor therapy.

低剂量电离辐射可明显增强荷瘤机体的免疫功能，可能具有肿瘤治疗的潜在临床意义。

Recently, with the development of the tomograph imaging technologies and the computer technologies, a new anatomic voxel model of animal could be constructed to review and evaluated the old points made with the old mathmetic or simple models.

近年来随着层析成像技术和计算机技术的迅速发展，开发准确而真实的生物体解剖模型已经成为可能，原有的许多非常重要的生物电离辐射效应的观点和结论都需要被重新审视和评估。

It decays to form products that emit a type of ionizing radiation.

它衰变形成一种产品释出电离辐射。

The ionizing radiation effects and hardness mechanism in fluorinated MOS structures have been investigated systematically.

摘 要：对含FMOS结构的抗电离辐射特性和机理进行了系统研究。

A unit of energy absorbed from ionizing radiation, equal to100 ergs per gram or0.01 joule per kilogram of irradiated material.

拉德电离辐射吸收的能量的单位，等于受照射物质每克100格或每千克0.01焦耳

Commonly,office with air-condition lacks of natural airiness,people breathe out CO2,the fog that is coursed by smoking,some office equipment.These things emante maleficence to bulk in the office.There are wet resorting in the air-condition system,this becomes the "dirt-hiding place".Computers,displays,hand-holding telephone and other electric equipments can produce certain amount of ionization radialization.Some building materials also release certain injurant.

带空调的办公室一般缺乏自然通风，人们呼出的二氧化碳、吸烟产生的烟雾、某些办公设备散发的有害气体积聚其中；空调系统里有水分滞留，成为某些细菌、霉菌病毒的&藏污纳垢&之地；电脑、显示器、手持电话及其他电子设备均产生一定剂量的电离辐射；有的建筑材料本身也释放某些有害物质。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
