A prediction model has been proposed to deal with threshold voltage shift as a function of 1MeV neutron flux and gate oxide thickness, and to deal with room-temperature annealing of threshold voltage shift induced-by 〓Coγ as a function of electric field and gate oxide thickness. The commonness and individuality of MOS device degradation between hot-carrier effect and ionizing radiation were investigated. The dependence of substrate current, gate current and threshold voltage shift due to hot-carrier on gate oxide thickness were simulated with MEDICI-2D simulator. The photocurrents of PN junction and bipolar transistor were studied. Their transient responses on varied bias voltages, pulse durations and absorbed doses were simulated. The influences of NPN base width on base and collector photocurrents were investigated. We also studied 1MeV neutron displacement damage in PN junction, and calculated reverse current leakage under the neutron flux of 2. 67×10〓 per square centimeter. 3 The study of nondestructive screening method for MOS radiation tolerance A theoretical and experimental study of nondestructive screening methods for radiation tolerance of nMOS and pMOS were firstly fulfilled. We determined the informative parameters pertinent to the method and proposed how to deal with experimental data and verify obtained results statistically, as well as make the required steps for nondestructive screening. Based on the experimental data of 180 samples of discrete pMOS devices, the relation between sample quantity and correlation coefficient, screening equation, and other significant results were obtained from the threshold voltage shifts of pre-and post-irradiation samples.

Nano-Fe_3O_4 can induce DNA single-strand breaks without significancy and can not induce micronuclei formation and percentage of apoptosis. Nano-Fe_3O_4 can aggravate the effect of CdCl2 on DNA single-strand breaks and chromosome damage in HepG2 cells. They showed synergistic effects on DNA single-strand breaks after the data were statistic analyzed.

结果发现CdCl2能引起DNA断裂损伤、微核率的增加和细胞凋亡率的增加；nano-Fe_3O_4能引起DNA断裂损伤增加，但无显著意义，未引起微核率和细胞凋亡率的增加；nano-Fe_3O_4能加重CdCl2的对细胞DNA断裂损伤和染色体损伤，且二者联合作用对DNA断裂损伤的结果经统计分析认为有协同作用。

Many respiratory diseases can result in Hemoglobin Saturation being lowered in human blood. Moreover, the following factors can also lead to problems in oxygen supply, so that human hemoglobin saturation might be reduced: Automatic Organic Regulation Malfunction caused by Anesthesia, Intensive Postoperative Trauma, hurts resulted in by some medical examination and etc. In the situation, illnesses, such as light head, asthenia, vomitory and etc, might happen to patients and even endanger the patient's life.

许多呼吸系统的疾病会引起人体血液中血氧饱和度的减少，另外由麻醉引起的机体的自动调节功能失常、大手术创伤、以及有些医疗检查引起的损伤等，都可能导致病人的氧供给发生问题而降低了人体的血氧饱和度；致使病人出现头晕、无力、呕吐等症状，重者则会危及生命。

在胁迫过程对照植株光合速率的下降是由非气孔因素引起；锻炼植株光合速率的下降在胁迫的前两天是由气孔因素引起，在胁迫的第三和第四天是由非气孔因素引起。这也从另一个角度证明了低温锻炼提高了植物的抗寒性。

The vocabulary in portrayal of characters with the same designative meaning may have the same or partly same associative meaning in different nations.

指称意义相同的人物肖像描写词汇在不同民族中有些可以引起相同或部分相同的联想，有些则仅在一个民族中引起丰富联想，而在另一个民族中不能引起联想，因而造成了汉英翻译中其联想意义的亏损，导致貌合神离，为了将这种文化上的亏损程度降低，在翻译中应采取变通手段进行补偿。
