We show that degree-correlated scale-free networks are robust to random stimuli as well as the uncorrelated scale-free networks, while assortative scale-free networks are more sensitive to directed stimuli than uncorrelated networks.

我们的研究表明：度关联无标度网络过对随机刺激鲁棒，这一点与度无关网络一样；但是匹配无标度网络对定向刺激的敏感性比度无关网络更强。

By using of signed directed graph deep knowledge model and inverse direction inference technique, the problem of on-line misoperation autodiagnosis during computer simulation training can be solved effectively.

采用符号定向图(SDG，Signed Directed Graph)深层知识模型配合反向推理方法，可以有效解决仿真训练过程中误操作实时在线自诊断问题。

The lysis efficiency was about 90% for heat-inducible vector or around 30% forUV inducible vectors. This set of autolytic units should be transferable to other vectors.

本体系能够通过简单的物理方法，将具有生物活性的胞内酶释放到胞外的，解决了定向进化的一个瓶颈问题。

The polarizer having high polarizing activities and durability to heat and moisture was prepared by dipping the newly synthesized azoxy dye into oriented and stretched polyvinyl alcohol film.

Besides, the key biosynthetic genes were cloned and then expressed for directional breeding in molecular level .

同时，对福提霉素生物合成的关键基因进行克隆和表达，尝试在分子水平上的定向育种。

Then, under the control of systemic factors, mesenchymal cells aggregate and differentiate to form catilage blastemal elements that prefigure skeletal limb components.

脊椎动物胚胎期骨与关节系统的发生是一种复杂生命现象，起始于中胚层间充质细胞的定向聚集，形成肢芽，然后在一系列作用因子的调控下，肢芽内细胞进一步分化，形成具有骨骼雏形的软骨原基，后者经软骨内骨化发育成骨。

The technology problems of blasthole depth,cutting blasting,smooth wall blasting,and directional blasting is discussed.

文章对炮眼深度、掏槽爆破、光面爆破、定向爆破等技术问题进行了探讨。

To investigate feasibility and effect of schizophrenia treatment by stereotactic lesioning, CRW stereotactic apparatus and PICKER spiral CT were used to define nucleus location and RADONICS radiofrequency instruments were used to lesion different subnucleuses of amygdala and the front part of callosal gyrus.

采用CRW立体定向仪和PICKER螺旋CT定位，用RADONICS毁损仪毁损杏仁核不同亚核团和扣带回前部治疗精神分裂症 3 5例，并进行了一年的随访。

Methods CRW stereo tactic apparatus and CT were used to define nucleus location and Radonics radiofrequeney instruments were used to lesion different subneucleus of amygdale and the front part of callosal gyrus. All schizophrenic patients were diagnosed by CCMD-3 standards.

方法对32例难治性精神分裂症患者，采用CRW立体定向仪和CT定位，用Radonics毁损仪毁损杏仁核不同亚核团和扣带回前部，采用临床疗效总评量表、简明精神病量表和阳性与阴性症状量表和韦氏智力量表等评定疗效，并进行1年的随访。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
