A chimeric primer was designated in which segment A near 3' end is complementary to HB plus strand just before the DR2 region gap, and segment B near 5' end is consensus to part of the human immunodefficient irus genomic sequence, without homogenetic relationship to HB genome.

设计一嵌合引物，使之3'端的A片断与HB正链互补，并恰好位于DR2缺口之前；5'端的B片断与人类免疫缺陷病毒的基因序列具有同源性，与乙型肝炎病毒的基因组无同源性。

However, if inextensible horizontal reinforcing elements are placed within the soil mass, as shown in Figure 1b, these reinforcements will prevent lateral strain because of friction between the reinforcing elements and the soil, and the behavior will be as if a lateral restraining force or load had been imposed on the element.

然而，如果在土体中加入无伸展性的横向加固元素，如图1b 所示，这些加固物会由于加固元素与土体间的摩擦作用而防止横向应变的发生，其性能就如同在加固元素上施加横向约束力或荷载。

It is shown that the reaction U+CO→CUO with a long-lived intermediate complex has no threshold energy, which agrees with the potenlial surface. When the collision energy is greater than 418.4 kJ/mol, the intercharge reaction increases, until the CUO molecule will decompose into U, C, O completely, and these reactions have threshold energy.

结果表明：在碰撞能低(15kJ/mol)时可以生成长寿命络合物CUO(X^3A)，并且该络合反应是无阈能反应；碰撞能大于418.4kJ/mol后，先后出现置换产物UO和UC；随着碰撞能进一步增大，CUO分子将被完全碰散成U，C和O原子，而且反应U+CO(0， 0)→UO+C，U+CO(0， 0)→UC+O和U+CO(0， 0)→U+O+C是有阈能反应。

It encodes a putative zinc finger transcription factor, and is a transcriptional corepressor for thyroid hormone receptors. Hairless gene plays a critical role in maintaining the delicate balance between cell proliferation, differentiation, and apoptosis in the hair follicle as well as in the interfollicular epidermis, and is concerned with the control of hair growth cycling.

无毛基因是与皮肤和被毛结构有重要关联的核受体基因，编码一个锌指结构转录因子，是甲状腺激素受体的转录辅阻遏物，并参与毛发生长周期的调控，在维持毛囊及毛囊间上皮的增殖、分化、调亡的精致平衡中扮演重要角色。

A chromium free conversion coating at least equivalent in corrosion protective quality to conventional chromate conversion coatings can be formed on metals, particularly cold rolled steel, by a dry-in-place aqueous acidic liquid comprising: a component of anions, each of said anions consisting of at least four fluorine atoms and at least one atom of an element selected from the group consisting of titanium, zirconium, hafnium, silicon, and boron, and, optionally, ionizable hydrogen atoms, and optionally, one or more oxygen atoms; a component of cations of elements selected from the group consisting of cobalt, magnesium, manganese, zinc, nickel, tin, zirconium, iron, and copper; the ratio of the total number of cations of this component to the total number of anions of component being at least 1:5; sufficient free acid to give the composition a pH in the range from 0.5 to 5.0; a component selected from the group consisting of phosphorus-containing inorganic oxyanions and phosphonate anions; and a component selected from the group consisting of water-soluble and water-dispersible organic polymers and polymer-forming resins and, preferably, also including a component selected from the group consisting of tungstate, molybdate, silicotungstate, and silicomolybdate anions.

通过对包含以下成分的含水酸性液体进行干燥，可以在金属上形成无铬的转换涂层，该涂层与普通铬酸盐转换涂层相比，至少在抗腐蚀质量上等效：$_一种阴离子成分，所述各个阴离子包括至少4个氟原子，至少选自钛、锆、铪、硅与硼元素中的1个原子。任选地可离解的氢原子，任选地1个或多个氧原子；$_一种选自钴、镁、锰、锌、镍、锡、锆、铁与铜元素的阳离子成分，上述成分的阳离子总数与成分内的阴离子总数之比至少为1∶5；$_足够的游离酸以使该组合物的pH值在0.5～5.0的范围内；$_一种选自含磷的无机含氧阴离子与膦酸盐阴离子的成分；$一种选自水溶性与水可分散性有机聚合物与聚合物形成的树脂的成分，优选还包括一种选自钨酸盐、钼酸盐、钨硅酸盐与钼硅酸盐阴离子的成分。

A random copolymer of poly(vinyl acetate-co-isopropenyl acetate) with number-average molecular weight of 9600 and relatively narrow molecular weight distribution （MWD, M w/ M n=2.03）was prepared by free radical copolymerization of vinyl acetate with isopropenyl acetate using AIBN as initiator.
