Our skin every day on their own metabolism, resulting from the basal cells gradually reach the skin surface, and then become a cuticle, the skin hyperkeratosis cycle is usually around 28 days, due to the environment, season, UV, rest is not normal and other factors, sometimes cause slow metabolism, so our skin piles up thicker stratum corneum, horny excessive accumulation, it will allow a transparent discussion so that the skin does not feel a sense of, and have lost the flexibility of the original, so fixed and the appropriate exfoliation, dander can be removed, so that the skin is more translucent.

我们的肌肤每天都会自行新陈代谢，由基底层产生的细胞会慢慢的到达肌肤的表面，然后成为角质层，皮肤的角化周期通常约为28天，由于环境、季节、紫外线、作息不正常等因素，有时会使新陈代谢变得缓慢，所以我们的皮肤表面角质层越堆越厚，角质过度的堆积，就会容议让肌肤感觉没有透明感，也失去原本的弹性，所以固定且适当的去角质，可以将皮屑去除，让肌肤更晶莹剔透。

The tenet of Vibroseis seismic exploration is outputting as much energy through a continuous bestirring in a period of time as that outputted by other sources in an instantaneous time. The realization of this goal needs that Vibroseis can output a same sweeping signal in many times continuously, then overlap the reflect signal to eliminate the noise from the exploration background, finally visualize the structure of the stratum.

可控震源地震勘探的精髓便是通过系统长时间的持续激励来实现其它震源的瞬时高能量激励，实现这一目标的前提是要求震源系统能够完成相同扫描信号的多次无差别输出，进而通过地震仪进行相应的垂直叠加，充分压制背景噪声，凸现地下的有用构造信息。

The ZOOMLION KSD25 Dry-Wet Horizontally directional Drill is the first drill which drills through hard rock without a bentonite and mud pump. Its pneumatic percussive technology has not only solved the problem of mud pollution, but also has increased its efficiency 40% higher than a normal drill. Additionally, its cost is also much lower, and therefore, it has been considered as a most efficient solution for complicated stratum (including pebble and gravel, backfill and rock).

中联KSD25干湿两用水平定向钻孔机是我国第一台不使用膨润土和泥浆马达就能在硬岩中钻进并导向的钻机，其国际领先的气动冲击钻机技术不但不存在泥浆污染的问题，而且效率比普通钻机提高40％以上，成本也要低廉得多，被公认为目前对付复杂地层（包括卵砾石、回填土和岩石地层）最为有效的方法。2 s# C J， k5 _% C
