阻断

For most linkages of IDS listen to the network data stream by the way of pass-by, it limits the ability of intrusion prevention.

而大多数入侵检测的接入都是采用pass-by 的方式来侦听网络上的数据流，限制了IDS 的阻断功能。

In comparison with antisense RNA,ribozymes can not only block but also cleave target RNAs.

其阻断有害基因表达的作用已得到证实。

So it may be necessary to block the overexpression of the VEGF in tumor cells with ribozyme technique,thus to prevent the cells from over proliferation,and search for a new treatment of the ovarian cancer.

因此，采用核酶技术阻断卵巢肿瘤细胞中VEGF的过量表达，有可能阻止肿瘤细胞的增殖，为卵巢肿瘤的治疗开创一条新途径。

AIM: To observe the inhibition of HBc/HBeAg expression in the 2.2.15 cell transfected by two-unit ribozyme.

目的： 观察针对HBV C区双位点核酶在细胞内阻断C区基因表达的作用。

Therefore, a great attention has been attracted into the filed of gene therapy for cancers with the ribozyme.

近年来，抗肿瘤血管生长和利用核酶高特异性阻断失控基因，或有害基因治疗肿瘤的尝试极为活跃。

All these results strongly indicate that two-unit ribozyme can inhibit hepatitis B virus expression in the cell.

该双位点核酶通过针对HBV C区基因的剪切作用，阻断C区基因表达，抑制了HBe/HBcAg的表达。

The effect of E was greatly depressed by phentolamine in untreated strips as well as reserpine pretreated strips.

在利血平处理及未处理肌条上，麻黄碱的作用均可彼酚妥拉明阻断。

Results: Compared with the baseline, REMS was significantly reduced in all groups treated with NBI in a dose-dependent manner, but not with vehicle.

考虑胆碱能系统对睡眠觉醒周期的作用，我们使用阿托品——M_1受体阻断剂，观察其对幼鼠睡眠的影响。

Based on the facts mentioned above, we hypothesize that blockage of CRF R1 receptor will suppress REMS in developing rats.

据此，我们提出这样的问题：使用CRF R1受体阻断剂后，是否会导致发育期大鼠快眼动睡眠减少？

However, the neurons containing corticotropin-releasing factor have the highest level of activity and secretion at the beginning of life, which parallels the development of REMS.

有可靠证据提示此类患者多数有REMS增多的倾向。而且给睡眠剥夺72小时的大鼠侧脑室注射CRF后可显著增加REMS反跳。CRF拮抗剂可以阻断睡眠剥夺导致的REMS反跳。

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。
