Thirty two point six percent (42/129) of menopausetransition women and 18.9％(60/318) of menopause women had breast structure changes,〓=9.26, P＜0.01. The frequency of breast structure changes decreased with decreasing ofserum of 〓 level and increasing of age. Four (4/29, 13.8％) in HRT group had breaststructure changes, which disappeared after discontinuing HRT or reducing the dose of HRTin 3 subjects. Conclusions: Most of normal menstrual women and menopause transitionwomen experienced Mastalgia; Mastalgia occurred in 89.7％ of subjects and lasted forabout 2 M. in the 1-year ccHRT; Image of breast ultrasound changed following menstrualcycle in normal menstrual women; Breast pain and breast structure change may be causedby higher 〓 and P level in luteal phase; The breast structure changes of HRT user weresimilar to that in normal women and were reversible.

大部分正常月经妇女和绝经过渡期妇女有周期性乳房胀疼，绝经后妇女应用17 β-雌二醇2mg加醋酸炔诺酮1mg连续联合治疗1年中大部分使用者有持续约两个月的乳房胀疼；乳腺体层厚度随体内雌孕激素水平的下降和年龄的增加而逐渐萎缩，绝经后妇女应用17 β-雌二醇2mg加醋酸炔诺酮1mg连续联合治疗1年后，对乳腺体层的厚度没有明显的影响；超声下乳腺结构改变主要受体内雌孕激素水平的影响，正常月经妇女中1／3的乳腺结构改变具有可逆性，绝经过渡期和绝经后妇女中有一半的乳腺结构改变的特征类似正常月经妇女具有可逆性的乳腺结构改变；绝经后妇女应用17 β-雌二醇2mg加醋酸炔诺酮1mg连续联合治疗1年后，少数使用者出现的乳腺结构改变可随药物剂量的调整或停药而恢复；对长期HRT使用者仍需加强乳腺的监测，长期HRT对乳腺的影响值得进一步研究。

Results of megascopic pyrolytic characteristics and the quantitative chemical dynamic analyses of these samples show that: although the occurrence and accumulation enrichment of immature and low mature oils are related to a number of different geological factors and conditions, under relatively low thermodynamic stresses organic matters related to immature and low mature oils do be matured to generate hydrocarbons.

这些样品的宏观热解特征和化学动力学定量分析结果表明，未熟─低熟油的产出和富集虽与多种不同的地质条件或因素有关，但在相对较低的热应力条件下，与未熟—低熟油产出有关的有机质样品确实能开始明显成烃。

Proposing that metallogeny in the region behaved as isospatial ore-forming.

提出矿区区域地质的演化与成矿的关系表现了明显同位成矿的特征。

Results Compared to control group, the epidermis thickness of irradiated group was not uniform, dermis vascellums were dilated, inflammatory cells infiltrated and collagen fibers were metamorphotic.

结果：与空白组大鼠皮肤相比较，模型组呈现表皮层厚薄不一，真皮层血管扩张，大量炎性细胞浸润，胶原纤维明显变性等典型光老化特征，造模成功。

There is a significant difference in daily change of soil moisture content at depth of 5 cm between the areas with and without microbiotic crusts.

结皮覆盖区与无结皮覆盖区土壤水分的日变化特征明显不同于距地表5cm处，而其他各土层的变化趋势则较为一致。

The strains from Microtus fuscus ,however,had unique characters,significantly different from the strains isolated from other parts of China.

从该县青海田鼠中分离的鼠疫菌株，其分子生物学特征与我国其他疫源地中的鼠疫菌株明显不同。

The result showed,the change of tobacco-leaf appearance is the most significant from tobacco hanged to the leaf became extremly red.In different modulative period, tobacco-leaf protein、reducing sugar and total sugar content,their correlation coefficient are negative;The methods of hot-windy cycle dry a...

结果表明，从上挂开始到烟叶完全变红初期，烟叶外观特征变化最明显；在不同调制时期烟叶蛋白质与还原糖、总糖的含量呈负相关；热风循环干燥法和远红外线干燥法均可缩短调制时间，减少用工量，且烟叶化学成分保持相对稳定。

There are 11 population distribution cores obviously instead of a monocentric pattern.

结果是：沈阳城市内部人口分布具有较高的不均衡性和聚集性；城市人口密度分布不符合单核心圈层式范式，具有11个明显的人口分布核心；在城市中心区域，人口分布的区域化特征更为显著；人口分布主要受到相近的两个人口核心的影响。

To summarize molecular, morphology, chromosome and pollen characters, the conclusion was reached that Epimedium was an nd monophyletic taxon. To divide the genus into any groups would be artificial. It is proposed that the disjunction by space, climate and seas were the main reason of respectively differentiation of each group by the view of geographic and climate changes in the temperate zone of the world. Because of its evolution-conservation, the disjunction did not bring about obvious divergence on the level of molecular and morphology.

综合分子特征和形态、细胞学、孢粉学等性状，提出淫羊藿属是一个进化上极为保守的、自然的单系的植物类群，进行属下任何阶元的划分都将是人为的，从旧世界温带的地质变化及气候变迁的角度推测，空间、气候和海洋的隔离是产生类群各自分化的主要原因，但由于其进化上极度保守，这些隔离尚未产生出类群间形态上和分子水平上的明显趋异。

On the basis of field work and flora analysis, this paper has chiefly discussed the characteristics of Helan mountain flora. The results show: 1. The plant species are comparatively rich, for there are 678 species of spermatophytes in Helan mountain area, belonging to 314 genera, 71 families. Among the 314 genera there are 16 monotypic, 17 oligotypic and 5 chinese endemic ones.

本文通过贺兰山植物区系的分析，指出该区系的主要特征是：植物种类相对丰富；地理成分复杂多样，并且有明显的过渡性；区系内部的地区性差异很大；除少数为古老类群外，多数是发生较晚的年轻类群；整个区系显示有较大的脆弱性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
