12V/24V low voltage power supply, which is used in ground light, is safe and reliable. Inside synchronic digital controller realizes the effects of color changing. Without connecting to outside controller and cords, the synchronic signal trigger function of the inside controller could make lots of ground lights change color at the same time, including flickering, gradual changing, scanning, chasing, running and etc. to satisfy the requirements of lighting in different places. The combination of light and shade draws a colorful city nocturne, breeding a vivid feeling of live and phantasmagoric. LED ground light it novelty lighting and the best choice of city nocturne.

In the presence of Pt catalyst, polyhydrodimethylsiloxane reacted with allyl polyoxyethylenepolyoxypropylene ether (F-6) by hydrosilylation to form an intermediate polyether silicone, which further undergo phosphation reaction with phosphorous pentoxide, a kind of phosphate modified polyethersiloxane surfactant was prepared.

采用铂作催化剂，通过含氢硅油和端烯基聚醚（F-6）的硅氢化加成反应先制得聚醚硅油中间体，再将其和五氧化二磷进行酯化反应，制得了一种磷酸酯型有机硅表面活性剂。

For this reason, some basic studies, such as the definition of the environment, systematic analyses of the ecosystem of man-environment, deep thinking about environmental problems, navigative proposal of environmental construction, assessment of environmental awareness and ethics, comments on importance of morals and laws, philosophical ponderation of environmental values, and discussion on relationships between science, technology and the environment are previously conducted in the dissertation.

为此目的，本文首先通过对环境的基本概念的界定、人类-环境系统的层次分析、环境问题的理性透视、环境意识与生态伦理、环境价值的哲学思考、科学技术与环境、从环境保护到环境恢复再到环境建设等方面的讨论，向读者介绍了自己对环境的若干思想和认识，这也为之后的研究作了必要的铺垫。在上述讨论中，尤以经济与社会的层次分析、环境保护与环境恢复和环境建设战略辨析、环境道德与环境法制及环境价值的哲学反思等方面的论述最能体现作者独到的见解与理性。

Firstly, the predesign is carried out by use of the conventional analysis, and then the acceleration curve of the cam driven component is processed and revised discretely according to the requirements of dynamics performance.. The design equation based on a Refined Finite-Difference Algorithm is established and the calculating process is realized by the computer programs. Consequently, the cam profile with good performance can be attained.

该方法先用常规解析法作初步设计，根据动力性要求对从动件加速度曲线进行离散化处理和修正，再用有限差分法建立凸轮型线的设计方程式，通过计算机程序进行计算求解，因而可以获得优良性能要求的凸轮型线。

The process of three-step countercurrentleaching is presented, in the first leaching step Fe as leading impurity inthe matte is leached priorly, Co and Ni are enriched in the residue of thefirst step and then are leached in the second leaching step with a lowconcentration acid, the residue from the second step containing hardleaching Fe, Co and Ni are leached with a high concentration sulfuricacid in the third step, and Cu stays in the final resude, the leachate of thethird leaching step is diluted and divided into two parts as the leachantsto the first and second leaching step.

在此基础上，提出了三段逆流选择性浸出技术：即第一段用低酸优先浸出钴冰铜中杂质铁，将钴镍富集到第一段的浸出渣中，第二段再用低酸浸出渣中部分钴镍，第三段用高酸浸出第二段渣中难浸的钴镍铁，将铜留在最终的浸出渣中，第三段浸出液经稀释，分流，分别返回至第一段，第二段作低酸浸出介质。

Though during our visit there had been a reduction of workforce due to the economic crisis, and only one out of 9 production machines was in operations, I thought, with the guarantee of the advanced scientific technology, and a strong responsibility towards the environment and its employees, in additiona to the strict production and sale models, this enterprise can quickly rejuvenize itself after the economic crisis!

虽然我们参观的时候因为经济危机的原因工厂刚裁过员，并且9台生产机器只开了一台。但是我想，有先进的科技作保障，又有对环境和员工负责的极其强的责任感，再加上严谨的生产和专业的销售模式。这个企业在经济危机后会很快重新焕发青春的！

Temporary personnel should not be allowed to reprocess endoscopes until competency has been established.

临时人员不应被允许作内镜再处理，除非已确定有资格。

We hope that development characteristic of commercial concrete in East China area in this paper provides thinking clue of re-examination and re-inspection of development of commercial concrete industry and equipment usage for broad readers samely.

苏州永盛逐渐意识到，随着苏州高铁、火车站和轻轨工程结束后，将逐渐没有大型工程可作，如果到那时再转向的话，将为时已晚，并且苏州永盛在苏州一个地区的巨大混凝土生产能力将无法得到释放。

SAUR was the ideal vehicle for buying shares—it had a stable cashflow and almost no debt. In 1988 it channelled borrowed money into Cofipex, a subsidiary, which then bought shares in Bouygues SA.

SAUR是一个购买股票的好理想工具——它有稳定的现金流也几乎没有外债。1988年它作中间人借款给子公司Cofipex，然后它再买入布伊格股份有限公司的股份。

Sequently, the material was implanted into bone of the animal and the dynamic changes at the material/bone interface were histologically observed.

再通过动物骨内埋植实验，按不同时期对材料—骨界面的变化作动态组织学观察。

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