Characteristics of a number of gates from the set of all generalized Toffoli gates are studied. Any permutation S is proved to be generated by a n-cycle δ and a permutation τ=i(subscript j, i together. It shows that any neighboring 2-cycle permutation can be generated by at most two NOT gates without ancilla bit.

Hg在N503-煤油支撑液膜体系中的扩散层厚度δa为1.57×10^(-5)m，膜内扩散系数d0为7.26×10^(-13)平方公尺/s，确立了Hg的渗透系数P方程。

Some of the safe mobile codes may be rejected to execute, since there is no way to verify statically that the symbol range value of an array subscript expression in PCC.

PCC的数组边界检查存在着由于无法确定数组下标表达式符号值的范围，而造成拒绝执行一些安全的移动代码等问题。本文给出的一种数组边界检查的优化及生成算法，不仅能够比较好地解决了这一问题，同时还生成了循环不变式注解中的条件谓词。
