According to the Interior Ministry's figures, the elderly comprised more than 9.1% of Taiwan's population as of 2003, making the silvering of this island's people all the more obvious. In recent years the ratio of senior citizens living alone has likewise crept upward. Bulging ranks mean a higher incidence of those hospitalized, along with the amount of hospital care needed for single senior patients, and self-care for those living at home. All this adds up to grave concern by healthcare personnel-i.e., how to provide effective healthcare appropriate to the needs of elderly persons living alone.

根据内政部92年老年人口统计已超出人口总数的9.2%，使得台湾人口的老化现象更为明显，近年来老人独居比率也有慢慢上升的趋势，由於老年人口增多，相对提升住院比例，而对於独居老人住院疗护及居家自我照顾的需求，更成为护理人员思考如何提供有效率且符合独居老人需求的护理。

这意味着当赞助商突然发现他们掉进陷阱时他们会损失上百万的投资：或许他们代表了一种重要的经济力量，或许他们就会变成西方人眼里的亲中派。

This doesn't mean I'm not in favour of having women in senior positions - women make up half the population and it seems a shame to have them so unrepresented at the top of companies.

这并不意味着我不支持女性担任高级职位--女性占总人口的一半，因此公司顶级职位中女性如此之少似乎是一种耻辱。

Mean allelic frequency of the captive population was 0.0948 and heterozygous ratio was 90.52%.

2圈养种群的等位基因频率为0.0948，杂合率为90.52%。

The impacts on the diameter levels V and VI were indicated as abnormal increase of survivorship, negative values of mortality and decrease of mean life expectance whereas the impacts on the diameter levels III and IV were opposite to the levels V and VI. The survivorship curve of the Quercus variabilis population was fit with Deevey II.

静态生命表分析较好地反映出栓皮栎种群生长历史中的消长过程，清楚地透视出20年前坑木择伐对种群动态的长期影响，即径级V和VI（直径8~12 cm）存活株数异常增加、存活率提高、死亡数和死亡率出现负值以及平均期望寿命降低；而相应地对径级III 和IV带来与径级V 和VI相反的作用。

Compared with the controls, both 10.0-10 000.0 μgL^(-1) of methamidophos and 100.0 μgL^(-1) of 17β-estradiol increased the mean population growth rate significantly.0.1-10 000.0 and 10.0 μgL^(-1) of methamidophos decreased significantly the average ratio of ovigerous to non-ovigerous females and the average mictic rate, respectively, and 1000.0 μgL^(-1) of 17β-estradiol decreased the total resting egg production significantly.

与对照相比，10.0~10000.0μgL^(-1)的甲胺磷和100.0μgL^(-1)的17β-雌二醇均使轮虫的平均种群增长率显著提高；0.1~10000.0和10.0μgL^(-1)的甲胺磷分别显著地降低了实验期间轮虫种群中的携卵雌体数／非携卵雌体数和混交雌体百分率的平均值；1000.0μgL^(-1)的17β-雌二醇显著降低了轮虫的休眠卵总产量。

The mean number of CAG repeats was lower in PP patients than in prepubertal and Tanner stage II girls, although it was within the normal range for the general population in both groups.

尽管PP病人的平均CAG重复片段在正常范围内，但低于青春期前的女孩和Tanner stage II青春期女孩。

Mean population densities of M.pennsylvanicus were higher in supplementally fed than in control sites only in low food tallgrass habitat.

仅在低等食物质量的高杆草栖息地内，投放附加食物可导致草原田鼠的种群密度高于对照样地。

In the case of granite, observation results indicate that the extending routes of active cracks are mainly intercrystalline, transcrystalline, inter-transcrystalline, and intracrystalline. When the strain rate is low, the long intercrystalline cracks are prevailing, and with increasing of the strain rate, the short transcrystalline and intracrystalline cracks gradually increase. The statistic results show that the active crack density increases with increasing of the strain rate, and the mean length of active cracks diminishes with increasing of the strain rate, that is, the induced damage in comminuted product increases with increasing of the strain rate. For the first time this dissertation integrates macroscopic results of comminution with active crack growth under impact loading. It elucidates why the dynamic comminution strength of mineral beds increases with increasing of the strain rate through the active crack extending, and analyzes the influence of structure and constitution of minerals on their damage under impact stress. It is authenticated that both the size distribution and the damage population of comminuted product can be characterized by the fractal.

为分析料层颗粒在冲击下的细观损伤效果，采用德国生产的ASM68K半自动图象分析仪对粉碎生成物中的损伤情形进行了观测，以花岗岩为例，观测结果表明花岗岩颗粒在冲击应力下的活化裂纹扩展路径主要表现为沿晶、穿晶、沿穿晶和晶内等形式，在低应变速率下，活化裂纹以沿晶裂纹较多，随着应变速率的提高，其它裂纹形式大量繁衍，统计结果表明活化裂纹密度随着应变速率的增大而增大，活化裂纹的平均长度随着应变速率的增大而减小，综合表现为颗粒的细观损伤程度随着应变速率的增大而增大；首次将应力作用下的活化裂纹演化特征与粉碎的宏观效果相联系，并就料层动态粉碎强度随应变速率增大而提高的现象从裂纹演化特征的角度进行了解释；分析了矿岩构造结构特性对损伤产生和分布的影响。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
