原位

In Planta transformation is a simple and convenient method of plant gene transformation.

原位转化是一种简便的植物转基因方法，在拟南芥中已经应用较为成熟，在玉米上的应用并不多见。

In bud stage of mustards ecotype Xuelihong and Yuanyejie were transformed with in planta vacuum infiltration by an Agrobacterium tumefaciens strain GV3101 carrying hy-gromycin resistance gene. Effects of different factors on transformation frequency with in planta vacuum infiltration were studied.

以蕾期的芥菜生态型雪里蕻和圆叶芥为试材，在携带潮霉素磷酸转移酶标记基因的根癌农杆菌菌株GV3101的介导下，对影响芥菜植株原位真空渗入遗传转化效果的真空渗入时间、根癌农杆菌悬浮孢子的浓度、渗入培养基、感染方式以及根癌农杆菌菌株等进行研究。

The P16 and cyclin D1 expressions was determined in the normal colorectal mucosa,polypous tissue and colorectal carcinoma by using hybridization in situ.the results showed that the positive staining of P16 was the highest in normal colorectal tissue,polypus was the second and colorectal cancer was the lowest.

采用原位杂交技术检测正常大肠粘膜、息肉及癌组织中P16、细胞周期素D1、（Cyclin D1）的表达情况，并结合临床资料进行分析。

XRD indicated that the replacement of the terephthalate anion by the polytungstate anion had little effect on the structure.

结果表明，经过同多钨酸根阴离子的交换以后，垂直于水滑石层板方向的平行层板方向的晶格参数值变小，平行层板方向的晶格参数值不变，(003)、(006)、(009)衍射峰处的层间距值比为3：2：1；交换过程没有改变水滑石的结构，水滑石原位生长在γ-Al2O3表面及内孔，比表面积由γ-Al2O3载体的219m2/g增加到247m2/g，孔径分布则由原来的2～11nm变化为3～4nm。

A potentiometric method for the determination of the apparent mean activity of NaCl in saline soils in situ was proposed.

使用锥形氯离子选择性电极和钠离子选择性电极，研究了在田间直接测定原位土壤中的氯化钠平均活度问题。

Trace lead in environmental water samples was preconcentrated in site and determined by flow injection-flame atomic absorption spectrometry.

以Amberlite XAD-2树脂与双硫腙通过N N基键合的形式合成了一种新型螯合树脂(XAD-H2DZ)，采用IR和TGA技术对其特性进行了表征，并将其应用于微柱现场在线采样新技术中，实现了环境水样中痕量铅的在线原位预富集和实验室中流动注射-火焰原子吸收系统的联机测定。

These solutions will produce in-situ gel formation when transmitted from non-physiological to physiological condition. These polymer systems once instilled in the cul-de-sac will prolong the precorneal resistance time and increase the ocular bioavailability of drugs.

这些溶液由非生理状态转变成生理状态时会产生原位成胶(In-situ gel formation)，因此一旦滴入眼睛穹窿内，可延长药剂在前角膜的滞流时间及强化其眼的生体可用率。

The commercialized liquid ophthalmic formulation is eliminate from the precorneal area immediately upon instillation because of lacrimal secretion and nasolacrimal drainage. This results in very low ocular bioavailability. The problem can be conqurered by in situ gelling system for ophthalmic drug delivery.

一般市面用液体眼药制剂常因滴入眼睛时，受到经常性的泪液分泌及鼻泪管的快速排液，因此呈现很低的生体可用率，此缺点可用原位成胶(In-site gel formation)输送系统来加以改善。

Theshese sole:olutiollns will produce In-situ gel formation when transmltted Tcl from non-physiologlcal to physiologlcal condition. These polymer systems once instilled In the cul-de-sac WIII prolong the precorneal reslstance time and Increase the ocular bloavallabillty of drugs.

这些溶液由非生理状态转变成生理状态时会产生原位成胶(In-stiu gel forma-tion)，因此一旦滴入眼睛穹窿内，可延长药剂在前角膜的滞留时间及强化其眼的生体可用率。

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。
