a。题目中的'over the rational numbers'是不是指四次多项式的系数是有理数，怎么能这么表达呢，为什么要强调有理数，系数应是整理罢。

At first, numerical simulation are made on the temporal developing gas-phase mixing layer where the convective mach number is in the region of subsonic(0.5) and transonic(0.8). For the temporal problem where Mc is 0.5, researches where the computational field contains different numbers of initial disturbances(so-called n period problem) are made respectively, and vortex's types of evolution in mixing layer including different numbers of initial disturbances are investigated; For the temporal problem where Mc is 0.8, the distinct shock let structure is obtained, and its mechanism is analyzed at the same time.

The gyrfalcon,an Arctic bird of prey, has survived a close brush with extinction;its numbers are now five times greater than when the use of DDT was sharply restricted in the early 1970's.

我只知道numbers是表示总量概念，但是具体是怎么用的也不是很清楚。。贴上LDOCE里面的解释，绿底字部分

The results showed: taurine has no significant effects on the numbers of erection, mounting, intromission and ejaculation, the latent periods of erection and catching in young rats, but can significantly increase the numbers of erection, mounting and ejaculation, obviously decrease the latent periods of erection and catching in old rats.

Zhan has determined the maximum and minimum numbers of positive entries of imprimitive irreducible nonnegative matrices with a given imprimitivity index. In this paper, we prove that if a positive integer is between the maximum and minimum numbers, then there exists an irreducible nonnegative matrix A with the given imprimitivity index and with the given number of positive entries.

非负矩阵是矩阵论中研究比较活跃的领域，不可约非负矩阵是比较重要的非负矩阵，本文分两部分，一部分主要在詹兴致教授的研究基础上研究了给定非本原性指标的不可约非负矩阵中非零元个数的连续性，肯定地回答了詹兴致提出的一个自然的问题。

The cells were passaged no more than 5 generations,and the cell freezing density is about 3×106 cell/ml, sample numbers of each kind are between 30 and 60, conserved numbers are 150-180 ampules,biological characters of fibroblast were analysed according to the request of constructing cell line. The results were as follows: 1 Cultured cells'morpha is typical fibroblast,which is fusiformate or unregular triangle, cells is radiant,flaming or rotative during growing .Qingyuan flesh chicken's cytoplasmic tubercle is much more and shorter in contrast with Zang chicken and Langshan chicken,that can be regarded as different character from others.

细胞冻存代数在5 代以内，冻存密度为3×106个细胞/ml，每个品种的样本含量在30～60 个之间，保存管数达150～180 支，根据建系要求，对成纤维细胞的生物学性状进行分析，所得结果如下： 1 培养细胞形态为典型的成纤维状，为梭形或不规则三角形，细胞在生长时呈放射状、火焰状或旋涡状走形，清远麻鸡的细胞形态与藏鸡和狼山鸡相比，胞质向外伸出的突起较多，且较短。

Secondly, the key techniques of the embedded database system in this experiment, such as memorizer management, query management and data synchronization replication, are further researched. The massive materials consult, the analysis and the research had been carried on and the key effects on the performance of the system had been discovered:(1) numbers of I/O of external storage;(2) numbers of repetition of parse SQL.

其次在实验的过程中，对嵌入式数据库系统中的存储管理、查询管理和数据同步复制等几项关键技术进行了深入研究，经过大量的资料查阅、分析和研究，找出了影响系统性能的关键所在：(1)外存I/O的次数；(2)重复解析SQL语句的次数。

Scores of somatization, sensitivity of interpersonal relation, depression, anxiety, hostility, fear, monomania, psychiatric and total scores, total average scores, positive numbers, and positive average numbers of the experimental group were higher than those of the control group（P＜0.01）. Correlation analysis showed that age was positively correlated with the mood of depression and negative copying（P＜0.05）, educational level was negatively correlated with the mood of depression and anxiety, and serum albumin was negatively correlated with negative copying（P＜0.05）. Conclusion: The mood of depression and anxiety is an obvious symptom in nondialysis patients with chronic kidney disease.

结果：慢性肾脏疾病组焦虑情绪、抑郁情绪和消极应对显著高于对照组（P＜0.01）；人格类型稳定性两组相比差异有统计学意义（P＜0.01）；两组心理健康状况相比，躯体化、人际关系敏感、抑郁、焦虑、敌对、恐惧、偏执、精神病性及总分、总均分、阳性数、阳性均数差异均有统计学意义（P＜0.01）；心理指标与被试变量的相关性分析显示年龄与抑郁、消极应对呈正相关（P＜0.05）；受教育程度与焦虑、抑郁呈负相关（P＜0.05）；血清白蛋白与消极应对呈负相关（P＜0.05）；而性别、职业、肾功能、血红蛋白与焦虑抑郁情绪、应对方式及心理健康状况总分、总均分、阳性数无相关性。
