The explants which showed vitrification could regerminate normal tepals when transfered to the medium supplemented with 6-BA 0.2 mg/L and NAA 0.005 mg/L, which demonstrates that decreasing the concentration of exogenous hormones could inhibit the vitrification.

玻璃化反应的外植体转移至MS附加6-BA 0.2 mg／L、NAA 0.005 mg／L的培养基上继续培养30 d后可再生正常的花被片，表明降低培养基中外源激素浓度能够阻止玻璃化反应继续发生。3。

There were some dedicted scientists who have contributed a lot for this project at its initial stage and who were the pillars of the project,but due to internal problems (you know the usual promotions,bias ,etc )and recent trends in software industry,the cream of them have taken up challenging top positions and more worthy jobs in other avionic companies like Honeywell ,Boeing,Hughes,BA and left in search of greener pastures(Its not because of renumeration,but for the poor recognition of their contribution ).

但也有一些勤勉的研究人员在该项目的初始阶段做了大量工作，他们是这个项目的支柱，但因为内部问题以及最近软件工业的发展，他们中的精华已跳槽到提供他们更有挑战性工作的公司如honeywell， boeing， hughes， ba，（并不是因为更好的待遇，而是因为在这里他们的工作的不到认可。

Rhyolitic volcanic rocks are generally characterized by rich alkali, silicon, aluminum,and poor calcium, magnesium. They have relatively high Rb,Th and rather low Ba,Sr,Ti,P,and exhibit obviouslv negative europium anomaly (δEu=0.16~0.44).The εNd values of the rhyolitic volcanic rocks range from -5.93 to -2022.Basalts and rhyolites in different cycles show clear geochemical variance.

流纹质岩石总体具富碱、富硅、富铝，贫钙、贫镁特征，其Rb、Th等元素的含量较高，而Ba、Sr、Ti、P等元素含量则明显偏低，并具显著的铕负异常（εEu=0.16'0.44），岩石的εNd值变化于-5.93~~-2.22.I、II旋回玄武岩和流纹岩在地球化学特征上均具明显变异。

Type I is composed of rhyolitic rocks, which are characterized by higher Si and alkali contents and lower Al and Ti contents, Na2O/K2O1 and a weak negative Eu anomaly (δEu=0.65–0.95), enriched in Sr and Ba and poor in Rb. Types I and II probably formed in an extensional to postorogenic extensional environment, accompanied by compressional uplift.

提要：大兴安岭北段根河地区早白垩世火山杂岩按岩石及其地球化学特征，可划分为3类：第Ⅰ类为流纹质岩石，富Si，碱，低Al，Ti，Na2O/K2O1，具弱的负Eu异常(δEu=0.65～0.95)，富Sr，Ba，贫Rb；研究认为第Ⅰ，Ⅱ类岩石产于挤压隆升相伴的拉张至造山后伸展构造环境。

In addition,the bitumen layer, such as Dingying and Mingxinsi formation should be given priority as potential source rocks. The organic type is Sapropel type. According to the trace element and the analysis in Sr/Ba, V/Ni, Sr/Ca, Ca/Mg, Th/U, it's proved that the sedimentary environment is marine.

通过对微量元素的分析，对Sr/Ba、V/Ni、Sr/Ca、Ca/Mg、Th/U进行了对比，证实了研究区当时的沉积环境主要为海相沉积环境，同时该区海水盐度逐渐降低，属海退系列沉积。

The effects of Ca(superscript 2+), Ba(superscript 2+) ion on sensitometric properties and aging stability of PTG materials, using AgSt as silver sources, ex-situ formed AgBr as photosensitive component, and PVA as binder, were investigated.

以常用的硬脂酸银为银源，异位AgBr为光敏元以及亲水型PVA为粘合剂，分别考察了Ca(上标 2+)和Ba(上标 2+)对光敏热成像材料照相性能以及老化稳定性的影响。

Using the young leaves of Sorbus folgneri as explants to induce callus, the best medium was 1/2MS+ 0. 5mg/L 6-BA+0.1 mg/L NAA+ 0. 5mg/L 2, 4-D, and the inducement rate could be up to 90%.

用石灰花楸的幼嫩叶片为外植体材料诱导愈伤组织，最适培养基为1／2MS+0.5mg／L 6-BA+0.1 mg／L NAA+0.5mg／L 2，4-D，诱导启动率达90％以上。

Mature embryos of Sorbus pohuashanensis were cultured on MS medium supplemented with different hormone combinations including BA, TDZ, IBA, 2,4-D and NAA.

以花楸成熟胚为外植体，在添加BA、TDZ、IBA、2，4-D、NAA组成的不同激素组合的MS培养基上培养。

Second, the left supramarginal gyrus (BA 40) was associated with reduced neural activity for phonologically-identical pairs with regular spelling to sound correspondences, when the mapping between orthography and phonology is made easy.

第二，当英文字对包含规则字时，由於字形与字音的转换容易，在左脑半球的顶叶下区(BA 40)产生大脑神经活动减少的现象。

A new concept of search world is presented, and the BA model of time synchronization network based on it is built. The model is also optimized to make the network more survivable.
