The appearance of DNA ladder from the ovules in which pollen chamber formation was undergoing, together with TUNEL assay and ultrastructural changes, demonstrated that the nucellar cell death, doomed to bring about pollen chamber, was a process of programmed cell death .

在贮粉室的形态发生过程中，相关珠心细胞的DNA电泳出现DNA ladder、其细胞核被TUNEL反应所标记以及它们的超微结构变化都说明，参与贮粉室形成的珠心细胞的死亡是一种细胞程序性死亡（programmed cell death，PCD）。

Methods:Eight parameters of cell nuclear in kidney cellules of 111 rats,including the tail length,the head radius,the percentage of head DNA,the percentage of tail DNA,the tail moment,the olive moment,the head area and the tail area,were determined at different interval within 72 h postmortem by single-cell gel electrophoresisand fluorescent microscope connected with auto-analysis-image system.

单细胞凝胶电泳(single cell gel electrophoresis，SCGE)技术于1984年由OSTLING等首先提出[1]，后又经OLIVE等[2，3]建立和改进，因细胞电泳形状颇似彗星，又称彗星试验。

The result showed HSV seropositive mice was really induced to produce tumor special or non-special factors, possibly included natural killer cell and lymphokine activated killer cell, which cooperated with mtHSV to kill tumor cells in course of mtHSV mediated tumor therapy. The effect in wtHSV seropositive mice was better than in mtHSV seropositive mice.

实验证明HSV免疫小鼠确实诱导产生了肿瘤特异性或非特异性因子，可能包括NK细胞和LAK细胞(lymphokine activated killer cell)，这些肿瘤特异性或非特异性因子在mtHSV介导的肿瘤治疗中与mtHSV一起协同杀死了肿瘤细胞，HSV-1F免疫小鼠的这种作用强于mtHSV免疫小鼠。

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。
