YMDD mutation: HBV YMDD mutation were developed in 12 lamivudine recipients, whereas the treated group had no incidence of HBV YMDD variation, there were significant difference between two groups (p=0.000). YMDD mutation resulted in increase of the mean HBVDNA levels (p=0.000), but no contribution to serum ALT diversification (p＞0.05). 2. Precore nt1896 mutation: Precore nt1896 mutation incidence had no difference between lamivudine recipients and objects who received combination therapy of Kidney-invigorating Granule and Marine Injection, and patients of HBeAg negative and HBeAg positive had a close incidence of precore mutation as well as. Precore nt1896 mutation had no influence on serum ALT level. The occurrence of precore nt1896 mutation contributed to serum HBVDNA load increased and worse response of HBVDNA extenuation. 3. HBV genotype: The baseline of serum HBVDNA gradually increase in turn of genotype B, genotype C and genotype B/C. Genotype B seemed to obtain higher rate of serum HBVDNA loss and HBeAg/anti-HBe seroconversion after combination therapy of Kidney-invigorating Granule and Marine Injection, differencing with lamivudine therapy.

疗效相关因素研究：1YMDD变异：对照组有12例检出YMDD变异，治疗组无1例检出，两组比较有显著性差异（P=0.000）；发生YMDD变异者血清HBVDNA和ALT水平均有所升高，HBVDNA平均水平高于非变异者（P=0.000）；血清ALT与非变异者无明显差异（P＞0.05）。2前C区nt1896变异：前C区nt1896变异发生率在治疗组和对照组以及HBeAg阴性和HBeAg阳性患者之间均无明显差异（P＞0.05）；1896c变异对血清ALT水平无明显影响；治疗组发生1896c变异者，其HBVDNA平均水平较之未变异者明显升高（P＜0.05），治疗后HBVDNA下降幅度明显低于未发生1896c变异者（P=0.000）。3HBV基因型：血清HBVDNA基础水平在B、C、B/C混合型间存在明显差异（P＜0.05），按B型、C型、B/C混合型依次升高；治疗组HBVDNA阴转率、HBeAg/抗-HBe血清转换率，B型似乎高于C型和B/C混合型，但无统计学意义（P＞0.05）；对照组HBVDNA阴转、HBeAg/抗-HBe改变在B、C、B/C混合型间无明显差异（P＞0.05）。

Deformation greatly promoted carbonitride isothermal precipitation and made C-curve shift leftwards. The position and shape of C-curve depended on the content of Nb and N to a great extent, C-curve shifted leftwards a little when N content increased and its nose temperature was raised with Nb content increased. 3 when cooling rate increased, start temperature and finish temperature of continuous cooling precipitation decreased, full precipitation became difficult to take place, the volume fraction of carbonitride precipitation decreased, molar fraction of Nb and C dissolved in austenite increased, and the precipitation grain was further refined. Deformation shorten precipitation start time during continuous cooling, raised precipitation start temperature, accelerated precipitation kinetics of carbonitrides.

计算表明：1在Fe—Nb—C系统中，随着温度的降低，析出相的平衡体积分数增加，溶解在奥氏体中的Nb、C的摩尔分数降低，析出相中C和Nb的原子分数的比值v增加；2变形大大促进了碳氮化物的等温析出，使C曲线左移，Nb和N的含量与C曲线的位置和形状有一定的关系，N含量的增加，使C曲线略有左移，而Nb的含量的增加使得C曲线的鼻子区上移；3随着冷却速率的增大，连续冷却析出的开始温度和结束温度均有所降低，并且析出变得越来越不充分，析出相体积分数明显减小，溶解在奥氏体中Nb和C的摩尔分数增大，析出相粒子被明显细化，变形大大缩短了CCP过程碳氮化物析出的开始时间，提高了析出的开始温度，促进了析出动力学。

Root-derived organic carbon is composed of three compartments: root detritus, root eaudates and root symbionts, which represents a large important and potential C sink in forest ecosystems, The known responses of root derived organic carbon and heterotrophic microbes to elevated CO2 were reviewed. Overall, increases in root biomass, productivity, and exudation indicate an augmentation of C inputs into the soil via roots, although changes in root lifespan are still unclear and may modify this flux positively or negatively, Altogether, changes in root chemistry and morphology that may augment soil C storage under elevated CO2 include decreased N concentration and wider root diameter, Alternately, a shift in rooting depth upwards in the soil profile may increase average turnover rates of root detritus. Effects of CO2 concentration on C qualities of root exudates and root symbionts are the least understood components discussed here, Changes of soil heterotropic microbial activity and community under elevated CO2 still remained large uncertainties.

林木根源有机C包括根东通过根枯落物、根系分泌物和根共生菌周转3条途径向土壤输入的有机C，它是森林生态系统中一个重要的、潜在的C汇，综述了根源有机C与其微生物对CO2浓度升高的响应，虽然对根系寿命的变化尚不清楚，但CO2浓度升高将导致根系生物量、生产量、死亡量和分泌物的增加；同时，CO2升高亦促使根共生菌生物量的增加而增加了共生菌的C归还潜力，表明CO2升高使根源有机C的输入增加了，CO2农度升高情况下，根系化学性质和形态特征的这些变化均有利于增加土壤C的吸存；而根分布深度的降低则对土壤C吸存不利；CO2浓度升高对根分泌物和根共生菌质量的影响研究则极少，CO2浓度升高下土壤微生物活性和群落组成的变化存在较大的不确定性，目前CO2浓度升高下林木根源有机C对森林长期C吸存的贡献仍很不清楚。

The initial rate V0 was influenced by the ratio of molar concentration for butanol to hexanoic acid C(superscript 0 subscript ROH)/C(superscript 0 subscript HA)(at a range of 0.2-17). As C(superscript 0 subscript ROH)/C(superscript 0 subscript HA) decreases, especially when C(superscript 0 subscript ROH)/C(superscript 0 subscript HA), the V0 increases rapidly.

反应初始速率V0与正丁醇和正己酸摩尔浓度的比值C(上标 0 下标 ROH/C(上标 0 下标 HA)有关，在C(上标 0 ROH)/C(上标 0 下标 HA)=0.2-17范围内，随C(上标 0 下标 ROH)/C(上标 0 下标 HA)比值减小，初始速率V0增大，尤其是当C(上标 0 下标 ROH)/C(上标 0 下标 HA)时，V0迅速增大。
