In the thesis some vital identities with binomial coefficient are given with their combinatorial proof, and the q-analogues of some identities are offered with corresponding combinatorial proofs on the subspace-lattice. Especially, one remarkable result is that a new q-analogue of the cube-sums identity is obtained with its combinatorial proof over the vector space.

Based on the electromagnetic induction law, Biot-Savart law and the numerical integration arithmetic, the vector potential of the busbar was calculated and the electromotive force of the planar coil for the single phase and three-phase busbar current was deduced.

根据电磁感应定律和毕奥-萨伐尔定律，运用数值积分算法，求解出汇流排导体矢量磁位，并推导了测量单相和三相汇流排导体电流时直线型线圈的输出表达式。

In Chap. 3, the concurrence vector for bipartite states is discussed in detail.

第三章详细介绍了两体量子态的concurrence矢量方法。

We have constructed a bivalence expression vector with SsNHX1 and AVP1 and transformed them into Arabidopsis. The results showed that the transgenic Arabidopsis plants 101 and 127 grew much better than wild type plants in the medium containing 100 and 200 mmol/L NaCl, which further indicated the important roles of Na〓 compartmentalization in vacuoles on plant salt tolerance.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
