诱导

It is shown that solvents may be classified by its effect into the active solvent and unactive solvent, and then, according to change of cold crystal peak area, effects of unactive solvents on the PET may be classified into three types: unchanged, reduced behind time and quickly reduced.

同时，对于非反应性的作用，依冷结晶峰面积的变化，又可分为三种类型：冷结晶峰面积不变，经诱导期后下降，无诱导期而迅速下降。

The results show that the weaken of crack directors has a little influence on stress release and little influence on stress distribution when the crack directors is uncracked. Once it cracked, the tension stress in the arch dam will reduce greatly.

实例计算结果表明：在诱导缝未开裂时，其削弱程度对坝体应力的释放程度有很小的差别，而对坝体应力分布规律几乎没有影响；一旦诱导缝开裂，则坝体中的拉应力大为降低。

In this study, We used longer DD primers in combination with a two-step PCR protocol to overcome these two problems in term of modified methods of Martin and Pardee.K562 erythroleukemia cell differentiation induced by HEMIN or PMA for 36 hours was used as erythriod or megakaryocytic differentiation model in vitro.Total RNAs were extracted from induced and uninduced K562 cells and were applied to mRNA differential display analysis.

为解决此问题，我们参照Martin和Pardee的改进方案［3］，建立了一种使用长引物，进行二步PCR的改进DDRT-PCR方法，以氯高铁血红素和肉豆蔻佛波酯诱导K562细胞36小时作为体外红细胞和巨核细胞分化模型，取诱导前后的细胞总RNA进行mRNA差异显示分析。

The immunofluorescence was developed with the mouse anti-VP4 serum. The results indicated that there was green-yellow fluorescence on the cell surface of pNZ8112-VP4 and pNZ8112-VP4-LTB when induced. The cells uninduced did not display an immunofluorescence reaction and were dyed red by Evans blue.

采用抗VP4的鼠血清进行免疫荧光试验的结果显示，pNZ8112-VP4和pNZ8112-VP4-LTB诱导后的菌体表面能看到黄绿色荧光，而诱导前的菌体则没有荧光反应，且细胞被伊文思蓝染成红色。

In uninduced HEL cells, GATA-2 transcription factor can specifically bind to the regulatory elements of human β-globin gene, including the proximal regulatory element (theβ-promoter) and the distal regulatory elements (the DNaseⅠ hypersensitive sites in the locus control region, HS2-HS4 core sequences).

在非诱导的HEL细胞的核蛋白中，能够与β—珠蛋白基因的近端启动子调控序列及远侧端LCR调控序列（HS2，HS3和HS4核心DNA序列）相结合的蛋白质主要是GATA—2转录因子，而在羟基脲诱导的HEL细胞核蛋白中，与上述调控序列相结合的蛋白质主要是GATA—1转录因子。

The DNA relative content of large unreduced pollen grains induced by colchicine was determined quantitatively with laser scanning confocal microscopy using the normal-sized pollen grains as control. The results suggest that the large unreduced pollen grains are diploid.

以正常花粉作对照，用激光扫描共聚焦显微镜对经秋水仙碱处理诱导出的大花粉进行了DNA含量的定量测定，初步确认该试验诱导的大花粉是一种二倍体花粉。

AIM: To study the effects of ursolic acid on human MCF7 cell apoptosis and the mechanism probably involved.

目的：探讨中药成分熊果酸（ursolic acid， UA）诱导MCF7人乳腺癌细胞的凋亡作用，并通过UA作用后的MCF7细胞Bax， Bcl2， cytochrome c蛋白表达的变化，探讨其诱导MCF7细胞凋亡的分子机制。

There is granular material on the top and the edge of the spikes induced by nanosecond laser pulses in air atmosphere, which is formed by solidification of the droplets. The micro-structures formed in air are different from the slender whiskerlike structures created by excimer laser and also different from the conical microstructures with dendritic nanostructures formed under femtosecond laser irradiation.

部分锥形上还有二次尖峰形成，空气中纳秒激光诱导的锥形尖峰微结构顶端和边缘有由液滴固化形成的粒状物质，不同于利用准分子纳秒激光诱导的细长须状结构和飞秒激光辐照下产生的具有表面枝蔓状纳米结构的锥形微结构。

In this study, we selected swine as a xenogenic origin and compared the effects of swine tooth germ cell conditioned medium with hTGC-CM on human DPSCs. in vivo and in vitro.

将猪和人的牙胚条件培养基分别诱导人的牙髓干细胞，并从体内、体外比较了猪牙胚条件培养基和人牙胚条件培养基对人牙髓干细胞的诱导作用。

According to the distribution of time resolved relative intensity of continuum emission of the plasma induced by laser ablating Al in Ar,we have briefly discussed the mechanism of the continuum radiation of the plasma induced by laser ablating Aluminum.

根据连续辐射强度的时间分布，简要讨论了激光诱导等离子体连续辐射的产生机理。根据连续辐射强度的波长分布，提出了原子对激光诱导等离子体连续辐射共振吸收理论。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
