H-BN thin films were prepared on the (100)-oriented surface of n-Si by r. f. sputtering physical vapor deposition. The field emission characteristics of the BN films were measured in a ultra high vacuum system. It has been found that the field emission characteristics of BN films is affected evidently by substrates temperature.

利用射频磁控溅射方法，真空室中充入高纯N2(99.99%)和高纯Ar(99.99%)的混合气体，在n型(100)Si基底上沈积了六角氮化硼薄膜，在超高真空0^(-7Pa系统中测量了BN薄膜的场发射特性，发现沈积时基底温度对BN薄膜的场发射特性有很大影响。

With temperature increasing, granular outshoot prefer to grow along with vertical direction of surface of BN core, as well as the wrapped leaf-like shape form from granular ones. And the productions always kept complete morphology of sphere, which was due to the uniform growth of fluffy film on the BN core. Wrapped leaf-like structure of BN piece in fluffy film favored increasement of measured surface area and elimination of oxygen element.

凝并在球核表面的中间产物受到初始BN球核在空间上的诱导作用，随着温度的升高，突出物倾向沿着垂直于球面的方向向外生长，形貌由普通的粒状转变为卷叶状；绒膜的厚度均匀一致，产品得以保持规整的球状形貌，绒膜中卷叶状的BN结构利于氧杂元素的脱除，同时增加了比表面积。

If the power series ∑anxn an ∑anxn and ∑bnxn satisfy the condition r =∑bn xn, we obtain the twin combinatorial identity theorem between the sequences {an} and bn}.We also obtain some specific twin combinatorial identities by using the expansion on the binomial expression formula, including two expansions of combinatorial number(rsn and ...

如果幂级数∑anxn与∑bnxn满足条件r＝∑bnxn 时，获得数列｛an｝与｛bn｝之间孪生组合恒等式的定理，应用在二项式定理等展开式上得出具体的多组孪生组合恒等式，其中包含组合数的两种展开法，Bernoulli数直接表达式的新证等结果。
