Stamens 5, usually inserted at base of corolla tube and adhering to stigma head to form gynostegium; filaments usually connate to form a tube enclosing ovaries; anthers 4-celled (Periplocoideae and Secamonoideae) or 2-celled, often with a membranous apical appendage; pollen tetrads contained loosely on a spatulate translator with a basal corpusculum, or pollen united into waxy pollinia, each attached through a caudicle to the retinaculum between adjacent anthers to form a pollinarium, pollinia 2 or 4 per pollinarium.

雄蕊5，着生于花冠筒的基部，与柱头贴生，和柱头粘生，形成合蕊柱；花丝通常合生成管包围子房；花药4室(Periplocoideae和Secamonoideae)或者2室的，通常有一膜质的顶端附属物；四合花粉松散地着生于匙形的载粉器上，具有着粉腺体，或者花粉合生成腊质的花粉块，通过花粉块柄与系接于着粉腺上，每个花药有花粉块2个或4个。

The intermediate-basic volcanic rocks with SiO2 content less than 57.48 wt% are high in Al2O3(20.22-16.34 wt%) and K2O, enriched in large ion lithophile elements, show obvious Nb, Ta negative anomaly, these are same to the basalts which formed in island arc. The andesite, dacite and rhyolite rocks with SiO2 content between 62.11-75.19 wt%, are similar with the I-type granitic rocks formed in island arc in their geochemistry. It is suggested that the Jueluotage area of East Tianshan was in island arc setting during Late Carboniferous, when the subduction of the ancient Asian Ocean was in progress.

其中w(SiO2)小于57.48%的中基性火山岩具有高w(Al2O3)(16.34%~20.22%)，较富钾，富集大离子亲石元素，具明显的Nb、Ta负异常；w(SiO2)介于62.11%~75.19%之间的安山岩、英安岩和流纹岩岩石化学特征与准铝质的Ⅰ型花岗质岩石相似，其地球化学特征也反映出岛弧花岗岩的特点，表明东天山觉罗塔格地区路白山一带在晚石炭世仍处于古亚洲洋向南俯冲的岛弧环境。

Microspar structures carbonate is characterized by elphent tooth-like structure consisting of fine, equant sparry calcite crystals, and hosting rocks is mainly fine-grained carbonates with mud.

臼齿构造碳酸盐岩是一种具有类似于大象臼齿特征的特殊碳酸盐岩，其微亮晶脉由纯净的、基本等粒的方解石构成，而基质物质则由细粒的、富泥质的灰岩组成。

The microstructure of the scaffold was observed under photomicroscope and scanning electron microscopy,and the in vitro degradation time,permeability,tensile-strength,porosity,shrinka...

实验结果显示：支架中的成纤维细胞、脂肪细胞及组织纤维间质完全去除，胶原纤维得到了松散，并维持其原有的天然三维网络多孔结构；该材料透水汽性处于3000g.m-2.d-1左右，适合创面恢复；体外降解时间处于25～50h之间，并可根据需要调整工艺条件控制降解时间；拉伸强度介于10.20～11.50MPa之间，具有良好的拉伸强度；收缩温度介于70～85℃之间。上述结果表明该材料已解决了猪脱细胞真皮基质渗透性差、降解速度过慢的缺点，并且其透气性和拉伸强度高、降解性优良且可控，符合组织工程支架材料的要求。

The breed of gilt-edged wind pear basically is to use cuttage method; It has stronger cent to give birth to ability, after be being spent every year, chairman of phyllome radical department gives new shoot, in those days autumn can cut next enter growing in pearlite and vermiculite compound matrix, wait for rooted hind go up again basin conserve.

金边风梨的繁殖主要是采用扦插法；它有较强的分生能力，每年花后，叶丛基部会长出新芽，当年秋季就可切下栽入珍珠岩和蛭石混合的基质中，待生根后再上盆养护。

These two series of probes differ in their mechanism of action. The first series exploits the concept of suicide substrate. When the probe is hydrolyzed by the target sulfatase, it will release an intermediate that undergoes elimination to form a reactive quinone methide which in turn reacts with nearby nucleophiles. The second series belongs to an electrophilic reagent which utilizes a cyclic sulfamate moiety serving both as the recognition unit and the trapping device.

这二系列标示分子的主要差异在於其标示机制，第一系列是源自於自杀性受质的概念，利用水解后的中间体会生成高反应性的quinone methide，来达到标示的效果；第二系列则是属於亲核性试剂型，采用环状胺基磺酸衍生物做为辨识端及捕捉机制，预期在其进入酵素的受质结合区后能与酵素催化中心形成共价键结。

The thiolation of protein and the coupling reaction of thiol protein with liposomes have been investigated, it was found that the degree of substitution was different in spite of the same molar ratio of SPDP to protein.

研究了蛋白质的巯基化和巯基化的蛋白质与脂质体的偶联。

Due to the insufficient supply of embryonated chicken eggs, the preparation of large quantities of inactivated influenza vaccines will require an alternative virus culture system after the emergence or reemergence of a pandemic influenza virus.

当流感病毒大流行的时候，用鸡胚培养方法生产的流感灭活疫苗不能满足大规模的需求。需要探索新的流感病毒培养基质。Vero细胞已作为多种人用疫苗的生产基质。

The properties of several rhodopsin sequences were analyzed by comparing withα2A-adrenergic receptor, and a great similarity was found between bovine rhodopsin andα2A-adrenergic receptor. Therefore transmembrane helices ofα2A-adrenergic receptor were constructed homologically based on the bovine rhodopsin.In the newly constructed structure, a 0.090 nm3 active-site, which was enclosed by several reported active residues, was found.

通过对比多个与α2A-肾上腺素受体同属G-蛋白偶联受体的视紫红质蛋白序列，选择以相似性最大的牛视紫红质蛋白为模板，同源模建了α2A-肾上腺素受体的跨膜结构，并在结构中找到了体积为0.090 nm3，已被报导的活性残基包围的活性位点。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
