Nanometer pearl powder creates the fourth times of pearl cosmetic----nanometer times. We select carefully limnetic pearl with high quality, adopt advanced super-sonic airstream physical manufacturing technic. Through super-sophisticated machine, we produce nanometer pearl powder with average diameterof 40-100 nanometer ( 1 millimeter = 1000000000 nanometer), equivalent to one hundredth of human body's pore, that is to say, by nanometer technic, we can powder one bead of pearl with 8 millimeter diameter into 64 trillion pieces, which means, everyone on the earth can have more than 10 thousand pieces.

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.

該方法將一根納米材料的兩端固定在兩個(gè)支點(diǎn)上，給納米材料施加一個(gè)軸向的微小拉力T亚洲是图宗合网；在納米材料的側(cè)面爱操屄，位于該納米材料的中部放置一個(gè)電極欧美淫乱a片，在電極上施加一個(gè)交變的電壓激勵(lì)納米材料使其發(fā)生共振欧美日韩二区在线另类，測(cè)得納米材料的固有頻率fwww.玖玖玖；根據(jù)納米材料的材料特性和幾何特征以及納米材料的邊界條件，由振動(dòng)方程計(jì)算出該納米材料的固有頻率與所受的軸向拉力的關(guān)系，即納米材料的f-T曲線；根據(jù)上述測(cè)得的固有頻率f，得到微小拉力T的大小91精彩国产福利在线。
