  1. En route, to his taciturn, and, not to put too fine a point on it, not yet perfectly sober companion, mr bloom, who at all events, was in complete possession of his faculties, never more so, in fact disgustingly sober, spoke a word of caution re the dangers of nighttown, women of ill fame and swell mobsmen, which, barely permissible once in a while, though not as a habitual practice, was of the nature of a regular deathtrap for young fellows of his age particularly if they had acquired drinking habits under the influence of liquor unless you knew a little juijitsu for every contingency as even a fellow on the broad of his back could administer a nasty kick if you didn t look out

    路上10 ，不但絲毫不曾失去理智確實比平素還更加無比清醒的布盧姆先生，對他那位沉默寡言的-說得坦率些，酒尚未完全醒的同伴，就11夜街之危險告誡了一番。他說，與妓女或服飾漂亮打扮成紳士的扒手偶爾打一次交道猶可，一旦習以為常，尤其要是嗜酒成癖，成了酒鬼，對斯蒂芬這個年的小夥子來說乃是一種致命的陷阱。除非你會點防身的柔術，不然的話，一不留神，已經被仰面朝天摔倒下去的那個傢伙也會卑鄙地踢上你一腳。
  2. The mechanisms of gene silencing include copy numbers and configuration of transgene, integration sites in plant and transcription of transgene, etc

    基因沉默的機制是多方面的，包括轉基因的拷貝數和構型、在植物上的整合位點、轉基因的轉錄水平等。
  3. Chloroplast genetic engineering, a new technology that could overcome many problems associated with nuclear genetic engineering, is of growing interest for bioproduction of valuable materials. it has several advantages including the extraordinarily high level of transgene expression and environmental safety, the favorable environment for prokaryote gene expression, the absence of " position effect " and gene silencing

    葉綠體基因工程是隨著植物遺傳轉化技術發展剛剛興起的生物技術，具有超量表達外源基因，為原核基因提供適宜表達環境，消除「位置效應」和基因沉默，環境安全性好等優點，較更適合用於植物生物反應器方面的研究。
  4. Though the technique of nuclejc transformation in plants has been developed and used widely, some problems in genetic information have not been resolved. for example, because the nucleic genome is so big and complicated that the integration sites and copies of foreign gene can not be controlled accurately, the expression of transferred genes is inefficient as a result of gene silencing or position effect. in nucleic transformation, furthermore, the transfer of multigene is difficult, and only after the prokaryotic genes undergo modification are they expressed in high plants

    植物的細胞核轉化技術已發展成熟並得到廣泛應用，但核基因組的遺傳轉化仍存在一系列至今尚未解決的問題：例如由於核基因組大，背景復雜，外源基因的整合位點和整合的拷貝數難以人為控制，造成鄭州大學2003年博士學位論文杜氏鹽藻（ dunaliellasalina ）葉綠體轉化研究外源基因表達效率低，容易出現基因失活、基因沉默、位置效應等現象;同時轉入多個基因時操作步驟過于復雜，所表達的原核基因必須經過修飾改造，環境安全難以保證等。
  5. In addition, molecular experiments indicated that resistance was not relevant to copy number or to insertion sites, but instead to the repeated gfp structure and to methylation of genomic dna. pvx vectors were constructed that contained the s6 gene of rbsdv vi and the 14 kd fragment of bnyvv rna2

    分子檢測結果顯示， gfp3植株中普遍存在gfp基因的沉默現象，且gfpdna的甲基化程度明顯高於gfp1植株，說明這些植株對于病毒的抗性與目的基因的插入位點及拷貝數和無關，但與串聯重復的gfp基因結構形式密切相關。
