无基础的

Because we can't control the disaster source in some years of the future, we can only decrease the losses through diminishing the vulnerability of the disaster affected bodies. But the vulnerability can't be diminished illimitably because of the limit of some condition, like fund. So, we must research how to get the largest safeguard through the fewest investment. The base of this kind of study is risk assessment.

在未来若干年中，人类还不可能控制灾害源和灾害载体，只能通过减少承灾体的易损性来减轻水灾对人类生命财产构成的威胁，但由于资金等条件的限制，人类又不可能无止境地减少易损性，这就必须探索怎样能以最少的投入获得最大的安全保障，这些工作的基础就是风险评估。

The results gained from MACONP are indentical with that of RETRAN02/MOD2 program. Then, Incontrollable Control Rod Withdrawal ATWS , Loss Of Offsite Power ATWS , Turbine Trip ATWS and Loss Of Feedwater ATWS are analyzed emphatically. Based on the LOFW-ATWS analysis, the sensitivity analyses of the influence of some conditions on ATWS process are conducted, such as pressurizer relief valve blocking, putting pressurizer spray in, no turbine trip and decrease of moderator reactivity coefficient. The simulating results agree well with corresponding results of RELAP5/MOD2, both analyses consequences are consistent in the main.

Both upper and lower dental study models were collected from 30 boys (12 years old) and 30 girls (12 years old) with acceptable normal occlusion to understand the characteristics of the crown size, dental arch width and length such as (1) mesiodistal diameters of crown size from central incisor to first molar,(2) the width and length of dental arch and basal arch and (3) the morphology of dental arch form. After statistical analysis, data were compared with Japanese, Central and South American Indians and North American Caucasians from papers. The results were:(1) There was no statistical difference in teeth size between males and females, except the upper first molar of males was larger than that of females, lower central incisor of males was smaller than that of females.(2) The dimensions of dental arch of males were larger than that of females in general, especially such items as width and length of basal arch.(3) The crown size of Chinese male was in generally smaller than that of four other races, especially the upper canine, lower central incisor and first molar.

为了解住在台湾的中国人其牙齿的大小，齿列弓幅径及形态，为齿科人类学上的特微，以期能对儿童牙科，齿颚矫正科之临床及齿科基础医学能有所贡献，抽取12岁学童男女各30名共60名，可接受为正常咬合之上下颚齿列模型，测量其上下颚(1)左侧正中门牙到第一大臼齿共计12颗恒牙之牙冠近远心径，(2)齿列弓宽径、长径及齿槽基底宽径、长径，(3)齿列弓之形态，以上资料经统计分析作t-test检定，并与诸学者对日本人、北美白人、中美及南美印第安人人种的研究结果作检讨得知；(1)男女性恒牙的近远心径无明显差异，但男性上颚第大臼齿比女性者大，下颚正中门牙比女性者小；(2)男性的齿列弓幅径比女性者为大，尤以齿槽基底宽径及长径最显著；(3)国人男子的牙齿近远心径比其他四人种者为小，特别是国人的上颚犬齿，下颚正中门牙及第一大臼齿最小。

Moreover, taking the adsorption process from oven-dry state to the equilibrium state in 20℃,60%RH environment as an example, the dielectric relaxation based on the reorientation of adsorbed water molecules was separated out from that based on the methylol groups in the amorphous region of wood cell wall.

以绝干状态→20℃，60%RH 平衡态的吸湿过程为例，将基于吸着水分子回转取向运动的介电弛豫与基于木材无定形区中伯醇羟基回转取向运动的介电弛豫进行分离，并在 Eyring 的绝对速度反应论的基础上，求得了与吸着水分子进行回转取向运动相关连的热力学量，得到了在吸着过程中吸着水分子与木材吸着点之间的氢键结合随着水分吸着进程的变化情况。

Loneliness, the common ground for terror, the essence of totalitarian government, and for ideology or logicality, the preparation of its executioners and victims, is closely connected with uprootedness and superfluousness which have been the curse of modern masses, since the beginning of the industrial revolution and have become acute with the rise of imperialism at the end of the last century and the break-down of political institutions and social traditions in our own time.
