| 9. | What s more , simple concurrent programming has been available on essentially all unix hosts since at least 1988 , which is when ksh standardized its " co - processes . " if you save the ksh source in listing 1 , below , as ex1 . ksh and then run it , you ll see a " countdown " - " ten , nine , eight , etc . " - display , then the result of the ksh subprocess : " all done . " in practice , you might use something like this for a long - running chemical calculation or database retrieval : launch the operation as a subprocess , but keep users informed about what s going on or how much time is left before completion
此外，至少自1988年以来，基本上已经在所有unix主机上实现了简单的并发编程，在1988年这一年ksh对其“协同进程（ co - process ） ”进行了标准化。如果您将下面清单1中的ksh源代码保存为ex1 . ksh ，然后运行它，您会看到“倒计时”显示： “十、九、八，等等” ，然后看到ksh子进程的结果： “ all done ” 。实际运用中，您可能会对长期运行的化学计算或数据库检索使用类似这样的操作：启动操作作为子进程，但是让用户始终知道操作的进展或完成之前还剩多少时间。 |
| 10. | A method is proposed to construct a localized active functional space from the density matrix of a large system . the large system is partitioned into central and surrounding areas . the active functional space is mainly localized on the central area . it contains all basis functions centered at the central area and all the orbitals which consist of the basis functions localized in the surrounding area and interact with the basis functions in the central area to a certain extent . an integral number of electrons are involved in the localized active functional space which can be considered as a relatively independent subsystem in the large system and for which formally isolated quantum chemical calculations can be performed . the related program has been coded and is checked through calculating the number of 4
