E. , to improve its real-time response speed, remove its priority inversion inside the kernel, and eliminate the nondeterministic time delay introduced into a running real-time process due to resource contension so as to enhance determinability in the kernel.

作者在归纳、分析的基础上，首先提出操作系统实时化的指导原则，即提高系统的实时响应速度，消除操作系统核心内部的优先级反向，及进程在执行过程中由于资源竞争而给程序执行引入的不确定时间延迟，提高系统的确定性。

In this paper, a new method of obtaining multi-coherent-beams by UR90 resonators coupled with forward-mode was given, by which a problem was called "detune" existing in method of backward-mode was resolved, and the reliability of system was enhanced obviously.

用多个UR90腔进行正向模耦合的方法来产生多束相干的激光，解决了反向模耦合中存在的失谐问题，可以大大提高系统的可靠性。

And the problem of "detune"existing in backward mode couple is resolved. So the reliability of the coupled laser system can be improved remarkably. At the same time, by using two copper vapor lasers with UR90s of M=1. 21 or AOUR90s of M=1. 5, the coherency beam combinations are implemented.

首次提出将多个UR90腔进行正向模耦合来产生多束相干的激光的方法，解决了以往采用反向模耦合方法中存在的失谐问题，可以大大提高耦合激光系统的可靠性。

Dioritic magmatic enclaves have been discovered in the subvolcanic ring dikes for the first time by this study. These enclaves have typical back-vein and quenched margin where there are a lot of needle-like apatites.

首次在相山北部次火山岩岩墙中发现的辉石闪长质岩浆包体，具有典型的反向脉及淬冷边，其淬冷边内含有大量的针状磷灰石。

Dioritic enclaves were discovered by the authors in thesubvolcanic rock dike of the northern part of the large collapse volcanic basin in Xiangshan, Jiangxi Province. These enclaves have a typical back vein and a quenched margin,and contain a large number of acicular apatites.

在江西相山大型塌陷式火山盆地北部的潜火山岩岩墙中，笔者发现了闪长质的岩石包体，这种包体具典型的反向脉及淬冷边，且淬冷边内含有大量针状磷灰石。

The robotic Denavit-Hartenberg theory was firstly introduced to describe the Tooling virtual assembly procedure. Then the Tooling assembly mathematical model was established based on the Denavit-Hartenberg inverse kinematics and virtual assembly space constraint relationships for describing the position of robots theory in 3-D space. And to solve the problem of length discontinuousness of standard parts, the position adjustment strategy for Tooling vacuum group was studied and presented.

首次引入机器人运动学Denavit-Hartenberg模型，基于反向运动学原理和虚拟装配的空间约束关系，建立了Tooling空间装配的数学模型，并根据Tooling装配所用标准件长度不连续的特点，进一步给出了Tooling吸盘组件的空间位置调整策略。

Finally, general requirements on thyristor reverse recovery charge dispersity dictated by valve design at giving system conditions are proposed.

最后，得出在系统条件一定的情况下，阀设计时对所选用晶闸管的反向恢复电荷分散性的一般要求。

Spp.. The melA locus is composed of a divergently transcribed α-galactosidase gene and a gene coding for a putative transcriptional regulator of AraC/XylS family.

halodurans 的 melA locus 是由一α-galactosidase 基因 melA 及其上游反向属於 AraC/XylS family 的转录调节基因 melR 所组成。

Different from the siRNAs or miRNAs, which are derived from double-stranded or short-hairpin RNA precursors, piRNAs are derived from single-stranded RNA precursors or two non-overlapping and divergently transcribed precursors without the involvement of Dicer endonucleases.

与来自于双链RNA的siRNA和发卡结构miRNA不同之处是piRNA来自长单链RNA前体，或者是两股非重叠的反向转录前体，其生成与Dicer无关。

Results An intracerebral echoless cyst could be visualized in all the three cases, in which" high-speed and low-resistance" blood signal could be detected by CDFI. There was direct communication between the vein of Galen and several basis cranii cerebral arteries without cerebral ventricle dilation. The dilated heart-breast rate could be visualized in all the three cases, two of which complicating with the dilation of superior vena cava and tricuspid regurgitation; two of which complicating with pleural fluid and abdominal dropsy; one of which complicating with edema of skin and polyhydramnios; one of which complicating with reversing blood signal of umbilical artery in diastolic phase.

结果 超声声像图显示3例胎儿在丘脑后下方、小脑上方有一无回声囊性结构，彩色多普勒超声提示无回声区内为高速低阻血流信号，与颅底动脉环间可见多条血管分支相通；脑室系统均未见扩大；胎儿心胸比增大，其中2例伴有上腔静脉内径增宽、三尖瓣反流；2例伴有胸腹水，1例全身皮肤水肿伴羊水过多，1例脐动脉舒张期血流反向。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
