The "regulable osteoinduction microcirculation/microenvironment system in vivo" has characteristics as follows: the culture conditions are controlled. For example, the release of a variety of growth factors can be controlled stably and quantitatively at bone defect site. Early nutrition and revascularization in the center of tissue-engineered bone can be effectively solved; some shortcomings resulted from construction of tissue-engineered bone in vivo, including secondary injury, high level technical requirements, and complex operation, can be avoided; vascularization and osteogenesis can be constructed simultaneously; simple safe and efficient operation.

可调控的体内灌注诱导成骨微循环系统具有以下特点：可以控制诱导培养条件，如调控各种生长因子微量稳定的缓控释放；能有效解决大块组织工程骨中心部位的早期营养和血运重建难题；避免了组织工程骨体内构建存在的二次损伤，需要较高的技术条件、操作较为复杂等缺陷；实现血管化与成骨的同步构建；操作简便，安全高效。

He drank what is now called Chateau Haut Brion at the Royall Oak Tavern in the heart of London, one of many such establishments that had sprung up after the return from exile of King Charles II three years earlier and which offered such new delicacies as tea, coffee and classy wines.

佩皮斯喝的是如今被称作奥比昂的葡萄酒，他是在伦敦中心地区的罗亚尔橡树酒馆喝到的。这家酒馆是三年前国王查理二世结束流放回国后迅速涌现的众多酒馆之一，提供茶、咖啡、上等葡萄酒等诸如此类的美食。

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。

Two reasons can be explained the improvements of catalytic activities after the addition of Ce. One is the increase of the thermal stability of Ni-B and Ni-P nanoamorphous alloys, which retards the nanocrystalline Ni to aggregate during the exothermal reaction of benzene hydrogenation. The other is to make their grain sizes smaller, thus it increases the number of activity center in unit mass.

说明加入Ce提高催化活性的主要作用有两方面，一是提高Ni-B和Ni-P纳米非晶态合金的热稳定性，抑制催化苯加氢反应时大量放热促使纳米晶Ni的聚集长大；二是使生成的Ni-B和Ni-P纳米非晶态合金颗粒更为细小，从而增加单位质量样品的活性中心数量。
