Successful separation of Cd-pheophytin a, Cd-pheophytin b, chlorophyll a, chlorophyll b, pheophytin a and pheophytin b in 14min was firstly accomplished by reversed-phase HPLC at a flow rate of 0.8ml/min, with the mobile phase of methanol: acetone (80: 20, v/v).

首次以甲醇：丙酮＝80：20为流动相，流速为0.8ml/min，在C〓柱（5μm，4.0×250mm）上，14min内成功实现了镉叶绿素a和镉叶绿素b配合物与叶绿素a，b和脱镁叶绿素a，b的高效液相色谱分离。

A portable photosynthesis system made by PPSYSTEM Ltd. was used to study the photosynthetic properties of 3 cultivarsof Rubus idaeus under the field conditions. The results indicated that the individual leave net photosynthetic rates had 2 peaks during a day,an obvious photosynthetic midday slump was observed in A,there was a significant difference in midday depression among the 3 cultivars;evaporation rates of B and C had 2 peaks during a day,while A had 1 peak,and an obvious midday slump was observed in B and C;Stomatic conductance is the key factor of midday slump;Compared with B and C,A had a higher water using efficiency,which will consume less soil water.

利用英国PP-SYSTEM公司生产的TPS-1便携式光合作用测定系统，对3个树莓品种的光合特性进行了比较研究，结果表明树莓叶片光合速率日变化呈双峰曲线，A品种&日中低落&现象明显，B、C品种不甚明显；B、C品种的蒸腾速率日变化曲线基本上为双峰型，日变化过程中的&午休&现象非常明显，而A品种为单峰型，日变化过程中的&午休&现象不甚明显；此外，叶片气孔导度与叶片光合速率的日变化趋势基本一致，呈平行变化趋势，说明气孔导度是影响光合速率的直接因子；较B、C品种而言，A品种具有较高的水分利用效率，说明其更能节约并有效地利用土壤水分。

In the subcase that K is doubly transitive on every block B〓, there is exactly one non-primitive connected arc-transitive graph on Z〓×Z〓p.

设Γ=Cay是G=Z〓×Z〓上的非本原连通弧传递图，B={B〓，B〓，…，B〓}是A=Aut在V=G上的非平凡完全块系，而K是A=Aut在B上作用的核。

As is known to all, pre-germinal center B cells carry unmutated IgV genes and GC B cells, post-GC B cells carry somatic mutated genes.

目前公认的是，生发中心前B细胞不含体细胞超突变，而生发中心B细胞和生发中心后B细胞表现出体细胞超突变。

Then we studied the double phase transition behavior of three-layer nanostructures with double thermoresponsive shells. Successive RAFT polymerization of NIPAM and 2-ethyl methacrylate or DMA and NIPAM were conducted using PS macroRAFT agent. The PS-b-PNIPAM-b-PDMA and PS-b-PDMA-b- PNIPAM triblock copolymers can self-assemble into PS-core micelles, which possess a three layer \'onion-like\' structure, with PDMA and PNIPAM blocks forming the inner layers or outer coronas.

另外我们还合成了含有PS、PNIPAM、PDMA三嵌段聚合物，也利用芘标记的方法可以得出：对于PS-b-PNIPAM-(来源：A29BC论文网www.abclunwen.com)b-PDMA胶束存在两个明显的相转变过程，第一个是内层的PNIPAM这一个很宽的温度(20-32℃)的塌缩过程，接着是32-50℃下的PNIPAM和PDMA的混合塌缩或聚集过程。

It not only corroborates the usefulness of Bower-Burgelman process model for conceptualizing strategy making activities , but also proved that B-B Model could apply to diversity of field .

本研究的结果不仅验证B-B过程模式在概念化策略过程管理活动的有效性，更进一步丰富了运用B-B过程模式研究的多样性与领域。

The porous media model of software FLUENT was introduced to simulate the 2D flow through permeable tetrahedrons,and an experiment was conducted to verify the simulation;With the simulation,the influence of parameters such as Re、relative width b/B and relative length l/B on the protected length downstream of permeable tetrahedrons was studied.

本文首次尝试利用Fluent软件的介质模型对经过四面体透水框架群的水流进行了平面二维数值模拟，通过模型验证，多孔介质模型能较好地用于四面体透水框架群模拟；另外，通过数值计算，研究了Re、相对宽度b/B、相对长度l/B对四面体透水框架群下游保护长度的影响。

The catenary outside saying besides, his definition can nod the join that stands to you directly namely, include to exceed join, anchorage join, also make retrorse connection, cite a case, a. B stands twice, if A stands to a join can choose a B station, so the retrorse join that A is B.

再说说外链，他的定义就是能够直接点到你站的连接，包括超连接、锚连接，也叫反向连接，举个例子，A.B两个站，假如A站上有一个连接能够点回B站，那么A就是B的反向连接。

The glass structure is of high stability due to the low ratio of B-O-B connection (16. 67%) although the minor amount of B in glass can exist as and .

玻璃中少量的B虽然可以和两种形式存在，但B-O-B的连接比例(16.67％)很低，因此玻璃的稳定性很高。
