These results indicated that palmatine had one common binding site on the immobilizedβ_2-AR column,the association constant was 2.93×10~4 L/mol at pH 7.2 and 25℃,while jatrorrhizine had two bingding sites,the association constants at these two sites were 1.93×10~4 and 1.56×10~5 L/mol,respectively.And the molar ratio of weak bingding sites to strong binding sites was 93:7.Palmatine and jatrorrhizine had competed for low-affinity site in immobilizedβ_2-AR.

结果表明，盐酸巴马汀与β_2-AR只有一类结合位点，在流动相pH 7.2，温度25℃时盐酸巴马汀与β_2-AR的结合常数为2.93×10~4 L/mol；盐酸药根碱与β_2-AR有两类结合位点，在这两类结合位点上的结合常数分别为1.93×10~4和1.56x10~5L/mol，两类结合位点数的比值为93：7，且盐酸巴马汀和盐酸药根碱竞争低亲和力的结合位点。

True leeches are subdivided into two groups; the first group is called proboscisless leeches and the second group is called jawless leeches.

分为两类，第一类称作没有鼻子和嘴的水蛭，第二类叫做无爪水蛭。

Extant jawless vertebrates, represented by lampreys and hagfishes, have innate immune receptors with variable domains structurally resembling T/B-cell receptors. However, they lack cardinal elements of adaptive immunity shared by all jawed vertebrates: T/B-cell receptors and major histocompatibility complex molecules.

在以七鳃鳗和盲鳗为代表的无颌类脊椎动物中，虽然发现了与有颌类脊椎动物T细胞受体(T-cell receptors， TLRs)、B细胞受体(B-cell receptors， BCRs)可变区具有相似结构的先天性免疫受体，却从未发现有颌类脊椎动物适应性免疫系统的核心组分：TCRs、BCRs、组织相容性复合体(Major histocompatibility complex， MHC)。

We have established primarily the nominal mothed and classified system acroding to the developmental pathways and the features of the glandular hairs of plants in labiatae in the ontogenesis. They are divided two groups, peltate and head and there are fifteen types.

在个体发育研究的基础上，我们按唇形科腺毛的发育过程和结构特点等，初步制定了唇形科腺毛的命名模式与分类系统，即把已经观察到的唇形科腺毛划分成头状腺毛类和盾状腺毛类两大&类&及其下的15&型&。

The khondalite series within Kongling Group in Yichang City, Hubei Province are composed of aluminum-rich schists-gneisses and garnet-sillimanite-quartzites, leptynite and mafic granulites, its protoliths are clay, sandstones-greywacke and marlite. REE distribution patterns of aluminum-rich gneisses incline NASC, Eu show negative abnormity and Ce displays no abnormity in chondrite-normalized REE distribution patterns.

湖北宜昌崆岭群孔兹岩系由富铝片岩－片麻岩及榴线英岩类、长英质岩类及镁铁质麻粒岩类组成，其原岩分别为黏土岩、砂岩－杂砂岩和泥灰岩，富铝片麻岩的稀土元素分配型式接近北美页岩组合样，Eu显示负异常，而Ce基本无异常。

Limonin and Naringin are the main bitters in citrus juice,so the citrus juice may become bitter.

柠檬苦素和柚皮苷等物质是柑橘类果汁中主要的苦味物质，果汁中因含有这类物质而具有苦味，因而会明显降低柑橘类果汁的口感和品质。

Limonin and Naringin are the main bitters in citrus juice, so the citrus juice may become bitter. And they can decrease the quality of citrus juice.

柠檬苦素和抽皮苷等物质是柑橘类果汁中主要的苦味物质，果汁中因含有这类物质而具有苦味，因而会明显降低柑橘类果汁的口感和品质。

Compounds, including 15 new C21 steroids, were isolated from the alcohol abstracts of the ratten of Marsdenia tenacissima. 37 of them are C21 steriods and their glycosides, the rest 5 compounds are lignans.

从通光散藤茎的乙醇提取物中，共分离得到42个化合物，其中包括C21甾体及其甾体皂甙类化合物37个，木脂体类化合物5个，有15个新化合物，均为C21甾体类化合物。

We suggest that the shocked meteorites could be classified into two groups; the group-A contains high-density phases, such as maskelynite and other high-pressure minerals; the group-B contains low-density phases, for instance diaplectic feldspar glass, molten glass and the assemblages of low-pressure minerals.

本文提出，陨石按照冲击变质特征可以划分为以下两类：一是含高密度相类，如熔长石和各种高压矿物；二是合低密度相类，如长石击变玻璃、低压熔融玻璃和低压矿物组合。
