After disinfection and medical activities before, samples were taken from three points in a diagonal of a relatively closed space with area not more than 30 square meters. In general, one point was from diagonal center, and the other two points from the two ends with one meter distance to walls. When the area exceeded 30 square meters, samples were collected from five points, one was from the center, and the other four points from four angles with one meter distance to walls, and the altitude was 80-150 cm from vertical distance to the ground. The total number of microbes not more than 200cfu/m^3 was considered qualified.

消毒后和进行医疗活动之前，相对封闭的空间，面积≤30平方公尺时，在一条对角线上取3点采样，一般是中心和两端距墙壁1米处各取1点；面积＞30平方公尺时，应取中央及四角距墙壁1米处共5点采样，布放高度为垂直地面80cm~150cm，微生物总数≤200cfu/立方公尺为合格。

For every ULA, the wide-band signals are sampled in spatial and temporal, then 2-D discrete Fourier transform is carried out. A projection operation on 2-D representation of wide-band signals is applied in the spatial-temporal frequency domain. The direction cosine relative to the ULA axes is estimated by MUSIC algorithm.

该方法采用3个共面的均匀线阵，每一均匀线阵对宽带信号空间采样，然后进行空时二维DFT变换，在空时频率域对宽带信号进行投影变换，用MUSIC算法实现宽带来波信号方向余弦的估计。

Results show that in the presence of CCI, the SER performance is less sensitive to estimation error.

结果表明相对于存在共信道干扰的情况，无共信道干扰时系统的误符号率性能更敏感于信道估计误差。

In order to discuss the interaction of viremia and antibody caused by reticuloendotheliosis and avian leucosis virus of subgroup J, REV, ALV-J and REV+ALV-J were injected to SPF chicken at 2 d separately, then tested the viremia and antibody dynamically for 7 weeks. The results indicated that compared with single infection, the dynamic viremia level of REV and ALV-J wasn't obviously different when coinfected.

为了研究禽网状内皮增生病病毒、禽J亚群白血病病毒共感染时对彼此病毒血症及抗体反应的影响，2日龄SPF鸡分别接种REV、ALV-J或同时2种病毒造成共感染，对各感染组7周内的病毒血症及抗体反应进行动态检测。

Consequently, when applied to minimize a strictly convex quadratic function, the proposed methods terminate at the solution of the problem finitely.

因此，当目标函数是严格凸的二次函数，且采用精确线性搜索时，这些修正的共轭梯度法具有共轭性和二次终止性。

To perform CRS stack depends on the determination of three wave attributes,compared with conventional common middle point stack and dip move out stack,CRS stack can focus more energy in the vicinity of the reflector,therefore can obtain a better zero offset section by stacking events with same phase.

共反射面元的旅行时响应由三个波场属性参数确定，相比常规共中心点(commonmiddlepoin ，CMP)叠加和倾角时差校正(dipmoveout，DMO)叠加，CRS叠加算子能够将地下反射点附近一个邻域内的能量进行聚焦并实现同相叠加，因此能得到更好的零炮检距剖面。

The biomechanical tests showed that two kinds of artificial bones had not significant difference on compressive strength and Young\'s modulus(P＞0.05),while the flexural strength of nano-nacre artificial bone was less than the control group(P＜0.05).3.The results of CCK-8 showed that the difference were not significant in each group,the proliferation of osteoblast reached the peak at the 5th day;7 days after being co-cultured,the total protein content of study group was higher than control group and blank group(P＜0.05),while the difference between control group and blank group was not significantP＞0.05The difference of alkaline phosphatase activities among three groups was not significant(P＞0.05The SEM view showed that osteoblast attached and grew well in two kinds of artificial bone.4.X-ray photography showed that two kinds of powder started to degrade in 2 weeks;this phenomenon became more appear in 4 weeks,nano-nacre powder degraded faster than micron-nacre powder,while the hole shadow was easy to be found;in 8 weeks,all the femoral holes recovered and returned to normal bone mineral density in all groups.Analysis of tetracycline fluorescent double marks in the hard tissue grinding slices indicated that new bone grew fastest around the bone defect area in study group,while most slowly in blank groupP＜0.05 SEM(scanning electron microscope observation showed that nano-nacre powder degraded more quickly.The same result can be found through the demineralized sections morphometric analysis,and both of the composite artificial bones made from those two kinds of nacre powder had the good connection with the adjacent tissue in rats body without apparent inflammatory response.5.X-ray photography showed that rabbit\'s bone defects healed faster in study group since NNAB implanted than in control group since MNAB implanted.At 24 weeks after operation,bone density in radial defects had nearly accessed to the normal area,while lower in control group,and turned up nonunion in blank group;The checking of BMD showed that results in study group were higher than those in control group at 8,16 and 24 week(P＜0.05), and the difference between the BMD values in study group at 24 week and those in blank group was not significant(P＞0.05).The gross specimens showed satisfactory histocompatibility both in study group and in control group,with bone tissue growing from two sides into the center of implanted materials; Normal slices in HE stain and hard tissue grinding slices in Stevenel\'s blue/Van Geison\'s picro-fuchsin stain showed that the bone growth tendency was better in study group than that in control group,and the medullary cavity had been penetrated to the implanted materials in study group at 24 week;Analysis of tetracycline fluorescent double marks in the hard tissue grinding slices indicated that new bone in both groups grew fastest 8 weeks after surgery,while slow down at 16 week.

纳米珍珠层/消旋聚乳酸复合人工骨与微米珍珠层/消旋聚乳酸复合人工骨分别与成骨细胞共培养后，其各时间点CCK-8法检测值与空白对照无显著差异(P＞0.05)，成骨细胞均在第5天达到增殖高峰期；培养7天后，实验组细胞蛋白含量高于对照组及空白组(P＜0.05)，后两者之间则无显著差异P＞0.05碱性磷酸酶活性在三组间均无显著差异(P＞0.05电镜下可见成骨细胞在两种人工骨上都有良好生长贴附能力。4.X-ray显示两种粉体在大鼠股骨骨洞植入第2周时都开始出现了降解，第4周时更为明显，纳米珍珠层粉较之微米珍珠层粉降解更快，而空白对照组骨洞阴影仍可见，至8周时，则所有组骨洞均己闭合修复，X-ray下已不可见原钻孔痕迹，恢复正常骨质密度；硬组织磨片四环素荧光双标记结果显示纳米珍珠层粉植入组较其余两组在骨缺损区周围新骨生长速度更快，空白组速度最慢P＜0.05电镜观察及常规脱钙切片亦可见到纳米粉体降解较快；由以上两种原材料制得的纳米珍珠层/消旋聚乳酸复合人工骨与微米珍珠层/消旋聚乳酸复合人工骨在大鼠体内均与周围组织结合良好，无明显炎症反应。5.X-ray显示纳米珍珠层/消旋聚乳酸复合人工骨植入兔桡骨缺损区后其骨愈合速度较对照组微米珍珠层/消旋聚乳酸复合人工骨植入的快，至植入术后24周，实验组骨缺损区接近正常骨密度，对照组骨缺损区密度较低，空白组则呈现骨不连状态；骨密度测量结果显示术后8周、16周、24周实验组的骨密度值高于对照组(P＜0.05，24周实验组的骨密度值与术前所测得的正常值无显著性差异P＞0.05动物取材大体所见均显示组织相容性良好，骨组织逐渐由植入材料两端向中央生长；常规切片HE染色及硬组织磨片Stevenel\'s blue/Van Geison\'s picro-fuchsin联合染色均可见实验组骨缺损区长势优于对照组，至术后24周，实验组骨髓腔与材料已呈相交通状；硬组织磨片荧光显微镜下观察，两组材料在术后8周处于骨生长最快速时期，16周时速度开始减慢，术后4、8、16周时实验组的新骨生长速度均较对照组的快

When the sample was subjected to high temperature for a long time before test, its co-continuous structure would be easily coarsened and disintegrated under the driving of interfacial tension.

试样在测试前长时间处于高温熔体状态时，其共连续结构很容易在界面张力的驱动下发生粗化和破碎，所以得到的共连续反而变窄。

The researchmethodology system is as follows:The variables that can be measured and have significance to stock relative intrinsic value are industry characteristic, profitability,development potential,qulity of earing and asset, the expandable potential of capital stock,the ability to pay off the debt,asset manging ability and the scale of the capital stock;(2)When the MFPM is established, the original variables should be disposed beforehand;(3)As for the research objects.we should value synthesizationly the achievement of the listed,and take the No.

本章所建立的研究方法体系为：（1）上市公司个股基本面因素中可以量化，并且对股票相对内在价值有重要影响的主要有行业特性、盈利能力、成长性、盈利质量及资产质量、股本扩张潜力、偿债能力、资产运营效率和股本规模大小等方面；（2）在建立MFPM模型时，原始指标值是不能直接用于模型计算的，必须对数据进行预处理后才能用于模型中：（3）在确定研究对象时，需要对上市公司经营绩效进行综合评价，在剔除主要靠未来业绩预期定价的第Ⅳ类股后，把第Ⅰ、Ⅱ和Ⅲ殴作为模型研究对象；（4）在选择多元回归模型时，由于原始自变量由于存在错综复杂的关系，尽管对原始自变量进行过预处理，但自变量指标依然会存在一定的多重共线性，为此在建立MFPM模型时，须采用逐步回归模型；（5）在检验MFPM模型有效性时，须从统计意义和投资实战意义两个方面进行。

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。
