Compact obturation is an important factor for root canal therapy, focusing on reducing the channel of entering root system through mouth and peripheral apical tissue and blocking excitant which is not completely removed during debriding and repairing root canal.

致密的封填是根管治疗成功的关键之一，其主要目的是为减少经由口腔或根尖周围组织渗透进入根管系统的信道，以及将根管清创、修形过程中无法完全移除的刺激物封闭于根管系统内。

With the Sand culture method, influences of different magnesium levels (0%、50%、100%、150%、200% and 300%) was explored to the wheat seedlings of different stages. Many targets such as plant height, root length, biomass, content of chlorophyll, activity of root, RGY, RGR and ratio of root to crown of the wheat were mensurated at the time of 7d, 15d and 30d of two leaves stage of wheat seedlings after their endosperms were removed at different magnesium levels.The results showed that different magnesium levels had unlike influences over the wheat seedlings.

以小麦为试材，采用砂基培养的方法，在镁浓度分别为对照组的0%、50%、100%、150%、200%和300%的营养基质上，培养剔除胚乳后的二叶期小麦幼苗7d、15d及30d，并分别测定该3个时间段小麦幼苗的株高、根长、地上部和地下部的生物量、叶绿素含量、根系活力以及相对生长速度、相对生长速率和根冠比等指标，研究不同供镁水平对不同时期小麦幼苗生长速率的影响。

Thank careless root to give me this chance, we also can try hard do, root wishing grass does better more, I can go for a long time careless root support!

谢谢草根给我这次机会，我们也会努力的做下去，祝草根越办越好，我会长期去草根支持！

And Changbai larch(Larix olgensis A.Henry)atdoubled CO2 concentration at seedling stage in growth-chamber and WI,HI of several dorminanttree species in MBKPF(1)Under 700μl·1-1 concentration of CO2,the stem height, stem diameter,main root length,root/shoot ratio and the relative proportions of biomass in root,stem and leaf of the seedlings ofKorean pine and Changbai larch had no significant change.

在700μL·L-1CO2条件下与正常浓度下相比较，在一个生长季后，红松、落叶松幼苗的苗高、地径、主根长、根茎比及生物量在根、茎、叶各器官中比例，差异不显著，对落叶松的侧枝数有影响；在第一、二次试验中，落叶松幼苗的平均每株生物量比在正常CO2浓度下大12.2％、14.2％，而红松幼苗的生物量分别减少3.9％、12.8％；红松、落叶松针叶叶绿素含量以及叶绿素a的相对含量在高浓度CO2下受到影响。

Methods The qualitative analyses of Kudzuvine root,Large-flowered skullcap root and Chinese goldthread of "Ge Gen Qin Lian" pocket preparation were finished.The reseachers analysed them with TLC method. Then they determined puerarin content of Kudzuvine root by TLC scan.

本实验采用薄层层析法对葛根芩连袋泡剂的主要中药葛根、黄芩及黄连进行了定性分析，并通过荧光淬灭薄层扫描法测定了君药——葛根中葛根素的含量。

Ingredients: organic Echinacea purpurea root 600 mg, licorice root 550 mg, licorice root dry aqueous extract 50 mg.

成分： 有机紫锥菊根600毫克，甘草根550毫克，水溶性干草提取物50毫克。

The main work of our research was to study the effects of the combination of enhanced UV-B radiation 0.35w·m~(-2 and Cadmium 1umol·L~(-1 on the growth, photosynthesis, elements absorption and relocation in mung bean seedlings at the initial stage of growth, and the involving mechanisms about the change of photosynthesis under the different treatments were studied also. It was shown that the heights root length, lateral root length, lateral root number, area of leaves, dry/fresh weight of the overground parts and underground part were all inhibited by the single factor and combinative factors.

本文以0.35w·m~(-2)剂量的UV-B模拟增强UV-B辐射和1μmol·L~(-1)Cd~(2+)模拟Cd~(2+)污染，研究了增强UV-B辐射和Cd~(2+)及其复合处理对绿豆幼苗生长、光合作用以及元素吸收和分配的影响，并对不同处理条件下绿豆幼苗光合作用的变化机制进行了比较深入的分析，获得结果如下：增强UV-B辐射和Cd~(2+)及其复合处理8天，绿豆幼苗植株高度、根长、侧根长、侧根数、叶面积、地上部分干/鲜重和根系干/鲜重均下降。

By mean of congruence transformation, when root of a polynomial has zero-root or double-root, a method for diagonalization of some Bezout matrics is given in this paper.

主要通过合同关系，对Bezout矩阵中当多项式存在零根和存在二重根时的对角化问题进行分析，得到一些有意义的结论。

1 Opens uses this function to enter the memory root table of contents, in the root table of contents can list the system to lack the province folder, the establishment material clamps (when for the first time opening machine or user has not changed table of contents with the user document, root table of contents only has system to lack province folder).

使用该功能进入存储器根目录，根目录中会列出系统缺省文件夹、建立资料夹和用户文件（首次开机或用户未更改目录时，根目录只有系统缺省文件夹）。

The results showed that, NO-3-N contents and nitrate reductase activity had obvious diversity in different spinach varieties and different organs of the same plant. The NO-3-N contents in stem were the highest, followed by petioles, then mesophylls, and were the lowest in roots. When the ratio of root to shoot was higher, the NO-3-N contents in plants were lower. NR activity was higher in root especially in lateral root. The NO-3-N contents in mesophyll and petiole were negative correlated with the in vitro -NR activity and in vivo -NR activity in roots.

硝态氮含量以短缩茎中最高，叶和叶柄中次之，根中最低，且根/冠比越大的品种，其整体植株中的硝态氮含量越低；根尤其是侧根NR活性较高；叶肉和叶柄中硝态氮含量均与根中以内、外源硝酸盐为底物的NR活性呈一定的负相关。
