The hydrolytic degradation research results showed that the PDLLA molecular weight was first degraded, then the weight loss happened in normal saline, and the water soluble crystallizable oligomers were formed during the process of degradation. The thermal degradation research results showed that the thermal degradation of PDLLA is a random breaking process, the molecular weight was degraded at range of 100癈~250癈, only above 250癈, the weight loss was found.

通过研究PDLLA的生理盐水降解性能和热降解性能，发现PDLLA在生理盐水中首先发生分子量降解，然后产生重量损失，且降解过程中生成具有晶体结构特征降解产物；PDLLA的热降解是一个无规的断裂过程，在100℃～250℃范围内，PDLLA的分子量迅速发生降解，在250℃以上，低聚物相继发生裂解，产生重量损失。

Despite their being genetically functionless, recent findings suggest that Alu elements may hae a broad eolutionary impact by affecting gene structures, protein sequences, splicing motifs and expression patterns.

尽管Alu在遗传学上是无功能的，但是在近些年的发现中推测Alus元素可能通过影响基因结构，蛋白质序列/剪接motif和表达方式从而有广泛的进化影响力。

What was observed under a light microscope included: tumor cells were mulberry and micropapillary shaped or were of glandule tubular arrangement; there was obvious interspace between cancer nest and neighboring areas; micropapillary was empty of fiber blood vessel axes, with micropapillae floating freely in spongy spaces and separated by fibrous septa.

Only the front waist of the abdominal cavity and soft iliopsoas, only in the vicinity of some of the muscles, ligaments and fascia, and other non-bony structures of protection, or lack of coordination in the weight-bearing exercise, vulnerable to injury.

腰部前方只有松软的腹腔和髂腰肌，附近仅有一些肌肉、筋膜和韧带等无骨性结构的保护，因此在负重或不协调的运动中，极易受到损伤。

Finally, the magnetic fields of three ironless PM motor prototypes, in which the experiment data have been obtained, are calculated and analysed. The calculated magnetic fields coincide with the experiment data. So the effectiveness and practicability of the ABCs method solving 3D open region problems are verified.

第四部分针对具有试验数据的三种结构的无铁心永磁电机样机进行了计算和分析，计算结果与试验数据吻合，从而验证了渐近边界条件法处理三维开域磁场问题的有效性和实用性。

Extant jawless vertebrates, represented by lampreys and hagfishes, have innate immune receptors with variable domains structurally resembling T/B-cell receptors. However, they lack cardinal elements of adaptive immunity shared by all jawed vertebrates: T/B-cell receptors and major histocompatibility complex molecules.

在以七鳃鳗和盲鳗为代表的无颌类脊椎动物中，虽然发现了与有颌类脊椎动物T细胞受体(T-cell receptors， TLRs)、B细胞受体(B-cell receptors， BCRs)可变区具有相似结构的先天性免疫受体，却从未发现有颌类脊椎动物适应性免疫系统的核心组分：TCRs、BCRs、组织相容性复合体(Major histocompatibility complex， MHC)。

In normal stomach wall, on the other hand, the SP-IR positive fibers were only found in myenteric and submucous layers, some fibers from the myenteric plexus can also be seen tending to the mucosa.

在癌巢内神经分布紊乱，无明显的层次，明显不同于正常的胃壁组织神经生长规则分布于黏膜下和平滑肌层的结构特点。

There isn' t overmany differences in the materials, structure, and manufacturing procedure of economizers, superheaters, reheaters and headers between 900MW supercritical pressure monotube boiler and the former boilers made in our company, except the size is bigger.

90 0MW超临界直流锅炉与上海锅炉厂有限公司以往制造的锅炉产品相比，其省煤器、过热器、再热器及相应集箱的材料、结构和制造工艺除了尺寸较大之外无大的差异。

As a new diagnostic method, DTI technology should be a routine examination for cerebrovascular diseases.3 DTI sequence should be added when the patient with cerebral ischemia has been examinated by routine MRI and found LA or cerebral infarction on acute stage in doubt. DTI can find hyper-acute and acute cerebral infarction immediately in order to treat the illness in time.4 DTI technology can reflect the mini-alter of alba formation pericerebral infarction with non-invasion in vivo. It can also appraise the degree of cerebral infarction and anticipate the result.

应作为脑血管病影像学常规检查。3对于临床上有脑缺血表现的患者，其常规MRI检查仅发现有脑白质疏松或怀疑有急性期脑梗死，应该加做DTI序列以便及时发现并治疗疾病。4 DTI可在活体无创性的反映脑梗死灶周脑白质结构的微细改变及评估缺血性病变损伤的严重程度和预测脑梗死结果。
