定向进行

To decrease the affection to the device under test, the power is always measured through directional couplers.

为了减小对待测系统的影响，功率测量一般通过定向耦合器来进行。

Their directional solidification is carried out by either Czochralski technology in the water-cooled copper crucibles or floating zone method without crucible, but the temperature gradient is not high with these two methods.

其定向凝固或者是在水冷铜坩埚内采用Czochralski技术进行，或者是采用不需要坩埚的悬浮区熔法实现，但这两种方法都不能得到较高的温度梯度。

To further elucidate the mechanism of BMP in regulating cell differentiation and to provide basis for BMP gene therapy, this study centers on the effects of BMP2 gene transfection on fibroblasts and contains the following works:① A 1.2kb fragment containing full length human BMP2 coding region was inserted into pBK-CMV (expressed both in protocaryon and eukaryon) by using predetermined orientation methods, resulting in phagemid expression vector for BMP2 (pBK-B2).② pBK-B2 was transfected into NIH3T3 cells by using LipofectAMINE.

为了进一步从分子水平探讨BMP对细胞分化的调控作用，并为BMP基因疗法的建立提供依据，本实验围绕BMP2基因转染对成纤维细胞的生物学作用进行了以下几个方面的工作：①将含有人BMP2全长编码序列的基因片段(1.2kb)定向克隆于噬菌粒表达载体pBK-CMV中，成功构建了人BMP2噬菌粒表达载体pBK-B2。

Methods:(1) Dissoluble PGN and CpG DNA were immobilized onto the surface of biotin cuvette for establishing target. Another effective tracking approach was established by immobilizing Escherichia lipid A F583 onto the surface of Non-derivatised cuvett. The biosensor technology was applied to screen anti-inflammatory TCM targeting on three key molecules.(2) The active compositions were isolated by AB-8 macroreticular resin from lycium bark. After the activities of compositions were evaluated, the most effective compositions was confirmed. In vitro, the affinities of different concentrations composition E binding with PGN, CpG DNA and lipid A were measured separately. The effect of composition E on vigor of RAW264.7 cells were tested by MTT and CCK-8, and its inhibition on TNF-α, which was released from RAW264.7 cells induced by PGN, CpG DNA and LPS, was also tested by ELISA. In vivo, murine sepsis models were made by intravenously heat-killed E.coli and heat-killed S.aureus, then protection of composition E on mice sepsis model were observed.

Gas molecules move freely among one another. The result is gas molecules diffuse from high-pressure area toward low-pressure area. The process is called gas diffusion.

气体分子不停的进行着无定向的运动，其结果是气体分子从分压高处向分压低处发生净转移，这一过程称为气体扩散。

Based on the data of directional core drilling, FMI, routine cores and their thinsections, we have described the characteristics of H3 reservoir in Anpeng oil field, Miyang sag. By analyzing the stable isotopes of 20 fracture infillings and 5 groups of acoustic emission, combined with the studies of fracture characteristics and tectonic evolution, the fractures in H3 member were assigned to the regional fracture type which is characterized by the dominance of vertical or highangle extensional fracture, occurring in groups, relatively stable occurrences and out of the control of local nosetype folds. It has been recognized that there are 4 breaking stages, of which the 2nd one is the major stage.

根据定向取心、成像测井、常规岩心及薄片资料对安棚油田核三段储层天然裂缝特征进行分析的基础上，通过对20个裂缝充填物的稳定同位素测定，5组样品的声发射实验，结合岩心裂缝特征、地质构造历史等，确定出核三段地层中裂缝为区域性裂缝，以垂直或高角度张性缝为主，成组出现，产状稳定，不受局部鼻状构造控制，确定出裂缝有4个破裂期，主要破裂期为第二期。

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.
