MATERIALS: Composite scaffold was made with collagen/chitosan/β-tricalcium phosphate. Upper layer was mainly collagen/chitosan, and lower layer was mainly collagen/chitosan/β-tricalcium phosphate. The factor of porosity was 90%, with antilinear of 100 μm.

材料：以胶原、壳聚糖、β-磷酸三钙制备复合支架，上层以胶原／壳聚糖为主，下层以胶原／壳聚糖／β-磷酸三钙为主，孔隙率≥90%，孔径100μm。

AARP actually will map addresses at any level of protocol stacks to resolve issues of AppleTalk node address availability used by the AppleTalk DDP, higher-layer AppleTalk protocols, and underlying data links providing AppleTalk connectivity.

事实上，AARP能够在任意协议栈等级查找地址，以解决AppleTalk DDP（Datagram delivery Protocol 数据包传送协议）、高层AppleTalk协议和提供AppleTalk连接性的下层数据链路所使用的 AppleTalk节点地址可用性问题。

It is designed to convey a sense of arrival and approachability, and to guide the visitors smoothly from the basement level into the superstructure.

它旨在传达一种意义上的有效性和渐近性，并引导旅客顺利从下层到上层建筑。

Argot applies especially to the language of the underworld or, by extension, to that of any specific group.

Argot 特别适用于下层社会的语言，或者通过引申，适用于任何特殊集团的语言。

We can also see from these seeds that we can detect in lower layers of the soil, that aromatic spices

我们还可以从在土壤下层发现的这些种子看出，当时人们在庆祝活动中使用了有香味的调料，并把它们

The trespasser crossed the room to its staircase leading down, while behind him the older man flickeredback into the view and repeated his action, sighting his astrolabe on a planet that had long since moved to

闯入者沿着室内的楼梯往下层走去，在他身后，那个老人的影像再次出现，用他手上的星盘去定位一颗早已不在那个位置的行星。

We do not for mail or schools, as has been shown by Federal Express and others, and by the ability of many private schools to provide superior education to underprivileged youngsters at half the cost of government schooling.

但是邮政或学校却无需社会主义，这已被联邦快递和其他的邮递服务所证实，也被许多私立学校的优越表现所证实。这些学校，较之公立学校，能对下层社会的子弟以减半的成本提供更佳的教育。

Ordinary Kriging, Co-Kriging and OKR interpolations were conducted with 72 SOC data in the topsoil (0~10 cm) which was selected as an auxiliary variable, and 36 and 24 SOC data in the subsoil (10~20 cm) as target variables.

以72个上层(0~10 cm)SOC数据为辅助变量，分别以36个及24个下层(10~20 cm)SOC数据为目标变量，分别进行普通克里格、协同克里格及OKR插值分析。

The method comprises the following steps: according to the raw water quality, the change of the number of bacteria inside the sedimentation tank and the water quality of the backflush yielding water, the backflush yielding water in the sedimentation tank is collected and deposited in a backflush phase of a working period; supernatant fluid containing mass active bacteria and soluble nutrient elements reflow to the sedimentation tank; total or partial sediment containing soluble nutrient elements in an underlayer reflow to the sedimentation tank and is reutilized by mass microorganisms in the sedimentation tank, thereby replenishing the nutrient substrate needed for microorganism growth, proliferation and metabolism under the condition of the low nutrition substrate, and maintaining the ecological stability in the sedimentation tank.

该方法根据原水水质和生物滤池内部细菌数量的变化以及反冲洗出水的水质，将生物滤池工作周期中反冲洗阶段的反冲洗出水收集并沉淀，将其含有大量活性细菌和溶解性营养元素的上清液回流至生物滤池，下层含有不溶性营养物质的沉淀全部或部分回流至生物滤池，被生物滤池当中的大量存在的微生物重新利用，从而补充在低营养基质条件下，微生物生长、增殖和新陈代谢所必需的营养基质，维持生物滤池当中的生态稳定。

Thirdly, surrounding rock deformation and failure process of layered rock mass in high geo-stress was reappeared through the physical models with different dip angle of rock stratum, and the stress change and failure discipline in the direction of vertical to bedding plane was definitely determined.

根据共和隧道砂质页岩的力学性质，运用相似理论，构筑不同倾角层状岩体的物理模型，研究了高应力条件下层状岩体围岩应力变化及变形破坏过程特征，确定了层状岩体在垂直于层面方向上围岩应力变化规律及破坏形态，揭示了深埋隧道层状岩体的破坏机理；物理模型实验研究得到的围岩应力变化规律及破坏特征与数值模拟分析的结果基本一致，同时也验证了横观各向同性弹塑性本构模型的正确性。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
