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.

试验与理论研究均表明,受压区钢筋锈蚀后对普通钢筋混凝土和预应力钢筋混凝土受弯构件的承载力影响均不大,但对构件的正常使用性能有较显著的影响,受压区钢筋锈蚀过程中,截面刚度有较显著的下降,挠度及受压区混凝土压应变随锈蚀量增加而增加,增加值与使用荷载大小有关;受弯构件的截面曲率所受影响最大,锈蚀后截面的极限曲率有明显的下降,在使用荷载作用下,截面曲率则随钢筋锈蚀量的增加而有较显著的增加;而预应力混凝土受弯构件的抗裂度会下降。

When the gas flux is constant, the ratio of reduced resistance is improved with the increase of the water stream velocity. However, the relationship between the gas flux and the ratio of reduced resistance is more complex. When the water stream velocity is constant, if the gas flux is small in contrast, the effectiveness of reduced resistance is not obvious. But when the gas flux increased, the jetted gas will form """"archform"""" which will augment the shape resistance. In this condition, resistance could not be reduced and could even be increased, if the gas flux continues to be increased. So that there needs setting a baffle called step, which introduces the jetted gas into the turbulence boundary layer. In this case, the shape resistance may be fairly great. Besides, the waterline of model has also some effect on the ratio of reduced resistance, which acts on the size of wave. If waterline is deep, the wave could not affect the deployment of microbubble layer, so there is almost no effect on ratio of reduced resistance. However, the wave would affect distributing of microbubble layer under the model so that the gas could leak out from the two sides of model and directly affect the ratio of reduce resistance if the waterline is very small. Whether installing the dashplate or not has also the great influence on the effectiveness the ratio of reduced resistance. From the results of experiment, conclusion is that adding dashplate will greatly improve the effectiveness of reduced resistance.

当喷气量一定时,水流速度增大,减阻率提高;喷气量与减阻率之间的关系比较复杂,速度一定时,如果喷气量较小,减阻效果就比较差,但当喷气量增大的话,喷射出的气体就会形成一个&拱度&,增加了船模的形状阻力,在这种情况下最好采取断阶喷气,把气体引入到湍流边界层中,在这种情况下,船模的形状阻力比较大;船模的吃水对减阻率也有一定的影响,主要表现在波浪大小上,如果吃水较深,波浪影响不到微气泡层的分布,对减阻率不会造成太大影响,如果吃水较浅,波浪就会影响到微气泡层在船模底部的覆盖情况,可能会有部分微气泡从船模两侧泄漏,这样就直接影响到了减阻效果;是否安装压浪板,对减阻率也有较大的影响,从试验结果可以看出,在船模尾部加设了压浪板时,减阻效果明显得到改善。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
