And ye shall be my people, and I will be your God.

30：22 你们要作我的子民，我要作你们的神。

For ye are not my people, and I will not be your God.

因为你们不作我的子民，我也不作你们的神。

And I will walk among you, and will be your God, and ye shall be my people.

26：12 我要在你们中间行走，我要作你们的神，你们要作我的子民。

One male goat shall be sacrificed as a sin offering, and two yearling lambs as a peace offering.

还应献一只公山羊作赎罪祭，两只一岁的公羔羊作和平祭。

From the graph, we can know that the graph of y=kx+b, is crossing the point of (0,b), and is parallel with the line of y=kx. And in the point of (0,b), o is x and b is y . In this situation, zero can be the divisor. It can be the scientific gist.

从正比例函数和一次函数的图象可知，一次函数y=kx+b在坐标平面上的函数图象是经过(0，b)且平行于正比例函数y=kx的一条直线，这其中的点(0，b)，0表示x，b表示y，在这样的情况下就成了零作除数的情景，这可说是零能作除数的科学依据。

objective:to evaluate the clinical effectiveness of titanium plate osteosynthesis in maxillofacial fractures.methods:216 maxillofacial fractures in 157 cases from 1998 to 2005 were treated with titanium microplate or miniplate osteosynthesis,122 of which were mandibular fractures and 94 of maxillary fractures.43 cases of maxillofacial fractures including cranial injuries in 157 cases and 38 cases including zygoma and zygomatic arch fractures and 13 cases including other injuries.results:most of the cases were healed.only 9 cases had complications.conclusion:the titanium plate osteosynthesis would bring about good effects.it would reduce facial malformation and regain normal occlusion after operations.

目的：对应用钛板作骨内坚固内固定的效果进行临床评价。方法：自1998年－2005年收治157 例共计216处颌骨骨折进行微型钛板或小型钛板作骨内坚固内固定术。其中下颌骨骨折122处；上颌骨骨折94处。157 例颌骨骨折合并颅脑损伤43 例，伴有颧骨弓骨折38 例，伴有其他外伤13 例。结果：多数病例能达到一期愈合，仅9 例伴有并发症。结论：钛板内固定具有良好的效果，术后面颌畸形得以改善，咬合功能恢复。

Chemiluminescent immunoassay is one of the advanced immunoassay ofnon-radioisotopic immunoassay because of its high sensitivity, wide dynamic range,high accuracy, stable labeled protein, full automation and extensive application field.CLIA using acridinium ester derivatives as chemiluminescent label has advantages oflow background, high signal-to-noise ratio, no need of catalyst and simpleluminescence system. Different aspects associating the DMAE·NHS-based CLIA were studied in thisthesis, including synthesis of acridinium ester, chemiluminescentcharacteristics of DMAE·NHS, labelling antibody or streptavidin with DMAE·NHS,two-site sandwich chemiluminescent immunoassay for TSH, two-sitesandwich chemiluminescent immunoassay involved biotin-streptavidinsystem for TSH, and competitive chemiluminescent immunoassay usingbiotin-streptavidin system for TT〓. The desired acridinium ester, DMAE·NHS, was synthesized according to thereference method with some modifications. The products were identified by IR, NMR,MS and elemental analysis. In our method, KOH was used in place of NaOH tosynthesize benzyl ester of 3,5-dimethyl-4-hydroxybenzoic acid,2',6'-dimethyl-4'-(n-succinimidyloxycarbonyl) phenyl-acridinium-9-carboxylate waspurified on a silica gel column with chloroform/ethylacetate(4:1, v/v) as eluent andfurther purified by triturating with hexane/acetone(2:1, v/v).

DMAE·NHS的合成是本论文的关键和难点，我们对文献方法进行改进：文献方法用氢氧化钠与3，5-二甲基-4-羟基苯甲酸反应制得3，5-二甲基-4-羟基苯甲酸钠，再用3，5-二甲基-4-羟基苯甲酸钠与苄氯作用制备3，5-二甲基-4-羟基苯甲酸苄酯，我们用氢氧化钾代替氢氧化钠，使合成取得成功；在合成2'，6'-二甲基-4'-苯基-吖啶-9-甲酸酯时，文献方法对粗产品进行两次硅胶柱层析纯化，第一次柱层析用氯仿／乙酸乙酯(4∶1，V∶V)作溶剂和淋洗剂，第二次柱层析用己烷／丙酮(2∶1，V∶V)作溶剂和淋洗剂，按照文献方法得到的不是所需要的化合物，我们只进行第一次柱层析纯化，然后用己烷／丙酮(2∶1，V∶V)进行研磨，过滤，洗涤，除去溶于己烷／丙酮(2∶1，V∶V)的部分，得到所需要的产品。

Titanium plate first was cleaned by glow Discharge using argon plasma to eliminate surface contaminants and to produce a consistent and reproducible titanium oxide surface layer. Then an intermediary allylamine deposition was covalently linked to the oxide layer by glow discharge, followed by the covalent binding of albumin to the free terminal NH2 groups using glutaraldehyde as a coupling agent. Surface morphologies were observed by scanning electron microscopy and atomic force microscopy.
