取1天龄大鼠、成年豚鼠、成年小鼠耳蜗标本经蔗糖快速浸透，用离心管定向并用新型组织包埋剂Tissue-Tek包埋，液氮中快速冷冻后在恒冷箱切片机中切片，然后分别做苏木素、伊红染色和免疫组化染色，观察组织切片的形态结构。

The plastic embedding techniques and the Leica SP1600 saw microtome could be widespread utilized in the study of histomorphology and the osseointegration surface of the oral implant.

塑料包埋技术适用于不脱钙硬组织包埋，制作含金属硬组织切片，可以广泛应用于含金属硬组织的组织形态学研究和口腔种植体的骨整合界面研究。

The experiment showed that the green algae in fresh water had a strong adsorption on plumbum,and the adsorptive efficiency would be 40% when pH was 4,the temperature reached 28℃ and the 2 g algae adsorbed the 20 mL liquor which contained Pb2+ of 100 mg/L.

结果表明，淡水中丝状绿藻对铅有较强的吸附能力，当pH值和温度以及包埋藻类的量控制在一定条件下，即pH值约为4，温度为28℃左右，按照2 g藻类处理20 mL质量浓度为100 mg/L Pb2+溶液原则包埋藻类，就可以使单位藻类吸附效率达到40%。

It was approved that the immobilized spherule had high biological activity, strength and mass transfer capability when PVA concentration was 9.0%, CA concentration was 1.0%,W/V was 1:1 and the cross linkage time was 24 hours.

在固定化实验中，通过正交实验对影响固定化细胞制备主要因素包埋剂、添加剂、包泥量以及交联时间进行条件分析，发现PVA作为固定化包埋剂的适宜包埋条件为：PVA浓度为9%、CA浓度为1.0%，包泥量为1：1、包埋时间为24h，包埋固定的小球具有较高的细菌活性，较好的强度及传质性能。

With DGD method, the electron microscopy observation has provided new information on the process of chromatin migration. That is: Firstly, the nucleus moved toward cell wall and a picture characteristic of synizesis stage of meiosis appeared; Secdonly, the transmigration of chromatin occured through CC, and a more extensive region constituted of nuclear skeleton left behind chromatin, which was named as"clear spaces" under light microscopy; Thirdly, at the late stage of synizesis, most of chromatin had gone into adjacent cells through CC and fused into a whole, and the nuclear skeleton left in the former cell gradually mixed with cytoskeleton in cytoplasm.

DGD—包埋去包埋电镜观察表明：百合花粉母细胞中有类似核纤层的结构存在；在染色质穿壁运动过程中，首先是细胞核向细胞壁靠拢，并可留下瞬间的运行轨迹——细胞核后方出现只有细胞骨架而少有细胞器的区域；其后是染色质开始穿壁，在穿壁染色质后方细胞核内出现无染色质仅有密集的核骨架的区域，到了染色质穿壁后期，大部分核物质都已穿至相邻细胞，并彼此融合，而残余在原穿出细胞中的核骨架己逐渐与原细胞的胞质骨架融为一体。

The nonwoven mess of polyglycolic acid coated with polylactic acid is extensively used as scaffolds in tissue engineering, but its hydrophobic charateristic and weak adsorptivity to cells limit its application.

以PLA包埋的PGA无纺网是应用较为广泛的支架之一。但其亲水性差，对细胞吸附力弱，是其不足之处。此实验选择了卵磷脂和多聚赖氨酸来分别和共同包埋PGA＋PLA，来观察其亲水性和对细胞吸附力的改变，及对细胞功能的影响。

Application of a few drops of Fixative No.1(2% glutaraldehyde in 0.1M cacodylate buffer at pH7.2) to the tissue before cutting into slices can prevent sticking and drying and initiate the fixing process. The air in the plant tissues prevent the resin to reach the organelles, which makes the fixation difficult.

由于植物组织中都含有一定的空气，致使树脂不能顺利浸润细胞器，这就给材料包埋带来困难，这可以通过在预包埋过程中处以真空处理以抽出植物组织中的空气，以便更好包埋。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
