硼同位素
英文

鹽湖硼氯同位素地球化學研究進展As is the case with everyday objects such as wineglasses or guitar strings, objects made from lower - mass materials have higher characteristic frequencies than otherwise identical objects made from higher - mass materials
將原有的鎂或硼以它們的同位素取代，我們可以製造出由不同質量的原子所構成的硼化鎂。The result shows that with the addition of rare earth elements, ultrasonic irradiation and magnetic field, the chemical component, surface configuration, microstructure and properties of electroless co - ni - b and co - fe - b alloy changes remarkably. such kind of change can be described as the followings. firstly the depositing speed of electroless alloy bath is raised while the polarizability and cathodic overpotential are reduced ; secondly the surface quality of the alloy coating and adhesion of the coating and matrix are improved ; thirdly in the coatings the content of the elements in the transient group increases, but the content of cobalt decreased ; fourthly the amorphous structure is transformed to microcrystal structure and polycrystal structure ; fifthly the microhardness and wear resistance of the coating are enhanced ; sixthly coercitive force is reduced, and magnetoconductivity of the coating is increased ; lastly the magnetic intensity of the coating increases with the addition of energy and light rare earth elements such as ce, la and decreases with the addition of heavy rare earth elements such as y. on the other side, when the alloy coatings passes through the heat treatment under the temperature of 250 or 500, their properties will change
結果顯示化學沉積co - ni - b 、 co - fe - b工藝在稀土元素（ ce 、 la 、 y 、 dy ） 、能量（超聲波、磁場）介入后，沉積過程、合金成分、鍍層形貌結構和性能都有顯著變化，表現在：鍍液的陰極極化過電位和極化度降低，沉積速度提高；鍍層的結合力、表面質量改善；鍍層中過渡族元素的含量增加，輕元素硼的含量降低，同時證實了稀土元素與過渡族元素共沉積的可能性；鍍層的顯微結構由非晶態向微晶和多晶態轉變；鍍層的顯微硬度與耐磨性提高，力學性能優化；鍍層的矯頑力降低；磁導率提高；鍍層的磁化強度在能量（超聲波、磁場）和輕稀土元素ce 、 la介入后提高，重稀土元素y介入后降低。Sedimentary - metamorphic boron deposits and their boron isotopic compositions in eastern liaoning province
遼東地區沉積變質硼礦床及硼同位素研究We have interpreted in the same way the production of radioactive elements in boron and magnesium in the first an unstable nitrogen with a half life of 11 minutes is produced, and in the second, unstable isotopes of silicon and aluminum
我們還用同樣的方式解釋了在硼和鎂中製造放射性元素的過程：首先製造一種半排出期為11分鐘的不穩定的氮，然後製造不穩定的硅和鋁同位素。For sgs phitonium standards and phitonium isotopic standards, in order to weigh the puo2 exactly, the materiel must be calcined at high temperature ( 1100 ? ) to guarantee the water not to be picked up by puo2 before enclosing container
對于sgs標準樣品和釬同位素標準樣品，為使裝容器前的iao 。不吸水，確保分裝含量準確，必須經過高溫川000的鵬，但檄燒過的puo硼完全娜，從而影響puo 。Separation of boron by using ion exchange technique for the isotopic measurement of boron in salt lake brine
