支点

As for the scientific background, the birth of the theory of evolution and ecology are closely linked with th

生态中心论则以自然价值、自然权利为前设，认为自然具有不以人类意志为转移的固有价值，这是生态伦理学的理论支点；自然拥有自我生存即不被人类利用的权利，尊重自然权利，这是人对自然负有的基本义务。

On the other hand,"Debutants' Social Talks" concerns about another type of artists who work in the pure world to explore a new art language - another world's language. It owns energy to shock the reality just because it has nothing to do, as only by virtue of a pivot beyond the world, we can prize up the earth.

而&新语&，关心的则是另一类艺术家，他们工作于纯粹形式的世界中，探索新的艺术语言，这另一个世界的语言，正因其与现实无关，才拥有了对现实制造冲击的能量，正如只有凭借现实之外的支点，我们才可以撬起现实。

The method is as follows that the two ends of a nanometer are fixed on two pivots and an axial micro-pulling force T is applied on the nanometer; an electrode is arranged on the middle part of the side of the nanometer and an alternate voltage is applied on the electrode to motivate the nanometer to generate resonance, and therefore, the natural frequency f of the nanometer is measured and acquired; according to the material characteristics and the geometry characteristics of the nanometer as well as the boundary condition of the nanometer material, the relation between the natural frequency and the axial pulling force of the nanometer, namely the f-t curves of the nanometer, can be calculated by a vibration equation; according to the measured natural frequency f, the size of the micro-pulling force T can be acquired.

该方法将一根纳米材料的两端固定在两个支点上，给纳米材料施加一个轴向的微小拉力T；在纳米材料的侧面，位于该纳米材料的中部放置一个电极，在电极上施加一个交变的电压激励纳米材料使其发生共振，测得纳米材料的固有频率f；根据纳米材料的材料特性和几何特征以及纳米材料的边界条件，由振动方程计算出该纳米材料的固有频率与所受的轴向拉力的关系，即纳米材料的f-T曲线；根据上述测得的固有频率f，得到微小拉力T的大小。

Adequate comparison and introduction is made on the structure and moving mechanism of typical gates applied in water and power works such as curve pedestal gate, fix double_supporting point gate and fix wheel link involute gate.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
