Because vegetation sourced photosensitizers are unstable, low concentration in plant and insignificant effect, we put our emphasis on a kind of chemical photosensitizers - xanthene.

由于植物源光敏化合物不稳定、含量低、效果差等一系列固有的缺陷，本论文着重研究了一类化学合成的光敏化合物——呫吨类化合物的光敏生物活性、光降解及开发利用。

As we know that human placentalsyncytiotrophoblast cell derlves from the fused cytotrophoblast cell and fetal calfserum can be able to induce the term placental cytotrophoblast cell fusion in vitro.

妊娠过程中，合体滋养层细胞分泌的hCG可促进卵巢黄体和胎盘分泌孕酮，在维持妊娠中起着重要的作用；然而未分化的细胞滋养层细胞不能合成hCGβ。

The stellate reticu-lum and the dental follicle of the underlying permanent tooth seems to be important for the deciduous root re-sorption. However, primary teeth without a permanent successor eventually exfoliates as well. Our current understanding on the underlying mechanisms is slim.

继承恒牙的牙囊和星网状层似乎在乳牙根的吸收中起着重要作用，而继承恒牙先天性缺失的乳牙根吸收最终仍会发生，其机制目前尚不明了。

The main aim of this thesis is to study normal families with conditions on fixed points of iterated functions and their applications.

众所周知，不动点和周期点在复解析动力系统中扮演着重要的角色，因此我们的结果是很有意义的。

The results corresponding hasbeen drawn a lot,however,studies on FRP Tubed reinforced concrete columns have been verylimited(The FRP tubes are used to transversly confine concrete,not bearing the axialloads).Based on experimental and theoretical analysis,the mechanical properties of the GFRPtubed reinforced concrete columns under axially loaded are researched.

而针对内置钢筋的FRF套管混凝土结构的研究较少(套管指FRP管不承受轴压力，仅起约束作用)，本文通过试验和理论分析，着重研究了GFRP套管钢筋混凝土组合柱的轴压力学性能。

The results showed that LOX-1 activity and endogenous MJ content in 'Rose Supreme' were higher than those in 'Advanced Red', with highest activties and contents in stolons, but not detected in leaves. It suggested that LOX-1 might regulate the development and growth of Gladiolus cormels through affecting the JAs biosynthesis cycles.

结果表明，唐菖蒲叶片中测不到LOX-1活性，匍匐茎中LOX-1活性和内源MJ含量最高，籽球数量较多的品种'Rose Supreme'LOX-1活性和MJ含量显著高于'Advanced Red'，说明LOX-1在唐菖蒲籽球形成和膨大过程中起着重要作用，其作用途径可能是通过影响茉莉酸类化合物的生物合成对籽球的发生和生长进行调控。

Because that the middle and upper atmosphere is a complex system of coupling between the dynamics, photochemistry and radiation, in this project, we mainl study the effects of the interaction between the dynamics, photochemistry and radiation on gravity waves propagation in the mesosphere and low thermosphere by using a photochemical-dynamical gravity wave model.

由于中高层大气是光化、辐射和动力相互作用的复杂系统，本项目集中探讨了光化和辐射所造成的非绝热过程对中高层和低热层大气重力波的影响，着重对中层顶区大气重力波不稳定机制以及光化-动力学耦合过程进行研究，并把计算结果与观测进行比较。

Compared with other CMS plants, the molecular basis of CMS rice is very unclearer, especially for those having been extensively used in hybrid breeding of China. So here, a serial molecular techniques are adopted to study the molecular basis of HongLian tylp CMS rice, taking sterile line , maintainer line , and hybrid F〓 HL No.

针对国内几种大面积推广的CMS水稻分子基础研究相对比较落后的状况，本文以水稻红莲型粤泰细胞质雄性不育系A和保持系B及杂种一代F〓为材料，运用一系列分子生物学技术和方法着重研究了红莲型水稻CMS的分子基础。

That is to say the transition zone which caused by the uneven distribution of subsurface fluids play a important role in the development and occurrence of strong earthquakes.

因此说，由流体存在而造成的过渡带或物性不连续界面对强震的孕育和发生起着重要乃至决定性的作用。

Disclosure is patchy and a plethora of measures exists, with most banks emphasising those that flatter them most.

信息的披露零散不全以及大量存在的衡量指标，而多数银行只会着重强调其中那些对自己最有利的信息和指标。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。

You were hired to drum up new business, so go and do it.

公司雇你招徕新业务，你就做你的事好了。
