Methods: We randomly collected 58 patients who had been suffering from androgenetic alopecia, and had been willing to accept the product trial after being informed. Then we obtained the macro images and micro images by dermoscopy as well in 0 weeks, 4 weeks, 8 weeks and 12 weeks. After observing these images, we measured the changes of numbers of terminal hair and its density parameter. In addition, we set up the experimental group and control group, and the efficacy was evaluated by own control.

研究了金属橡胶构件在不同方向的载荷作用下表现出来的各向异性，提出了用于分析金属橡胶材料内部结构的物理假设，并根据假设确定了各向异性研究的主要参数，然后通过实验研究进行了验证。实验结果表明，如果改变金属橡胶元件的相对高度，增加径向尺寸可以在很大范围内改变金属橡胶隔振器的径向刚度；要使金属橡胶隔振器的力学特性更近于线性，应让隔振器在径向范围内工作；如果隔振系统中含有多个承受压载荷的金属橡胶隔振器，则可以使其工作在与成型压力方向相垂直的方向。当相同结构和尺寸的钢元件和金属橡胶元件在承受剪切载荷作用时，这两种材料表现出了相同的刚度变化趋势。

The water parameters and their seasonal changes of Malus micromalus ,Prunusameniaca var ansu and Elacagnus angustifolia are studied by using P-V technique under field condition.

There was no change in the anthropometric parameters at the start and end of hGH/placebo therapy.

安慰剂组生长激素的人体测量参数在开始和结束没有变化。

To eliminate the limit, a hybrid objective function weighted by antitangent function is constructed, which behaves like an objective function of norm for small data points and like an objective function of norm for large data points, restraining the influence of false data points on inversion procedure.

针对航空遥感影像在拍摄过程中相关参数不易获取的问题，提出了利用逐行扫描及数据拟合的方法来获取影像整体灰度变化情况，从而实现影像渐晕现象的复原。

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.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
