改变

Typically, changes in output are achieved by varying the displacement of the engine (often through use of a arrangement), or by changing the quantity of working fluid, or by altering the piston/displacer phase angle, or in some cases simply by altering the engine load.

通常情况下，改变输出所取得的位移不同的引擎（通常是通过使用一种安排），或改变的数量，工作液，或通过改变活塞/置换相角，或在某些情况下只需通过改变发动机负荷。

The notable proliferation was not observed by eyes in the local of injection. The infiltration of inflammation cells and mild proliferation of fibrocyte around dura mater was observed by HE stained in 4 and 8 weeks after injection. Infiltration and exudation of inflammation cells was observed by HE stained in epidural nerve root. Compared with group A, no changes of group B, C and D were observed under specific stained. Proliferation of type Ⅱ collagen fibers around dura mater was seen under immunohistochemical stained in 4 and 8 weeks after injection. There is no significant demyelination changes under LFB stained. The thickness and shape of the myelin sheath in epidural nerve root was not regular under transmission electronic microscopy in 4 and 8 weeks after injection. Fibroblast was also seen there. In nerve endometrium, macrophage could be seen under TEM, myelinated nerve fiber changed significantly, but nonmyelinated nerve fiber changed mildly. When 8 weeks, the changes of group D is smaller than the group B and C.

四、在抑制返波振荡的方法中，改变聚焦磁场是一种比较好的方法，因为改变聚焦磁场几乎不会改变前向波的互作用条件，而会改变返波的互作用条件，因而既可以对返波振荡进行很好的抑制，又有利于提高效率。

Thirty two point six percent (42/129) of menopausetransition women and 18.9％(60/318) of menopause women had breast structure changes,〓=9.26, P＜0.01. The frequency of breast structure changes decreased with decreasing ofserum of 〓 level and increasing of age. Four (4/29, 13.8％) in HRT group had breaststructure changes, which disappeared after discontinuing HRT or reducing the dose of HRTin 3 subjects.

大部分正常月经妇女和绝经过渡期妇女有周期性乳房胀疼，绝经后妇女应用17 β-雌二醇2mg加醋酸炔诺酮1mg连续联合治疗1年中大部分使用者有持续约两个月的乳房胀疼；乳腺体层厚度随体内雌孕激素水平的下降和年龄的增加而逐渐萎缩，绝经后妇女应用17 β-雌二醇2mg加醋酸炔诺酮1mg连续联合治疗1年后，对乳腺体层的厚度没有明显的影响；超声下乳腺结构改变主要受体内雌孕激素水平的影响，正常月经妇女中1／3的乳腺结构改变具有可逆性，绝经过渡期和绝经后妇女中有一半的乳腺结构改变的特征类似正常月经妇女具有可逆性的乳腺结构改变；绝经后妇女应用17 β-雌二醇2mg加醋酸炔诺酮1mg连续联合治疗1年后，少数使用者出现的乳腺结构改变可随药物剂量的调整或停药而恢复；对长期HRT使用者仍需加强乳腺的监测，长期HRT对乳腺的影响值得进一步研究。

NodD binds to and bends target promoters through anchoring two tandem and individual specific DNA sites. NodD functions as a tetramer, which has a V-shaped main body. Tetrameric NodD is to change its own conformation rather than its oligomeric forms in response to small signal molecules. The specific interaction between each NodD DNA-binding domain and each specific DNA site does not alter itself in spite of naringenin induction, and the induced conformational change is transferred from protein to DNA. Only the DNA conformation incited by induced NodD is competent for RNA polymerase to form the transcriptional open complex. It cannot be excluded that NodD may have protein-to-protein contacts with RNA polymerase, and that the NodD conformational change may also directly contribute to the transcriptional open complex formation. However, the NodD conformational change itself cannot serve as the determinant of the transcriptional molecular switch.

通过研究，我们提出了初步的NodD操纵子激活模型：第一，四聚体是NodD蛋白的功能单位，它通过铆钉两个串联的相对独立的DNA靶位点结合被诱导的启动子；第二，小分子配基的结合是改变NodD四聚体的构象而不是引发不同形式的寡聚体，在我们的模型中，NodD四聚体缩小其V形主体的弯折角，进而缩短其DNA结合功能域的间距；第三，小分子信号的诱导并没有改变NodD的DNA结合域和其DNA靶位点的相互作用，NodD的构象改变由蛋白质经其双铆钉位点传递给DNA；第四，只有诱导状态的NodD激发的DNA构象才能有效地使RNA聚合酶形成转录开放复合物；第五，不排除NodD与RNA聚合酶可能有直接的相互接触位点，不排除NodD构象的改变可能直接有利于RNA聚合酶形成转录开放复合物，但是我们认为NodD构象改变本身不是充当转录激活开关的决定因素。

The new rT joint not only has two rotation axes that intersect at right angle,but also has another rotational degree of freedom which can be used to modify the assembly of other joints.This can change the mobility of the parallel mechanisms that assembled with the new rT joints and leads to two types of metamorphic paralllel mechanisms:In the first type,the mechanism changes its topology by turning the new rT joints in all limbs into different configurations which reconfigures the constraints within the limbs or the assembly of all the limb constraints.This change of mobility is completed by two cases.One is illustrated by a 3PS and a 3C parallel mechanism,by altering the rT joint into different configurations there will produce or reduce local degrees of freedom and thus change the constraits to the moving platform.This qualifies the 3PS and 3C to have variable mobility from 3 through to 6 and from 1 through to 6 respectively.

该铰链除了一般Hooke铰的两个轴线互相垂直相交的旋转自由度外，还增加了一个可以调节该两个轴线之一的姿态的一个旋转自由度，通过此自由度调节该rT铰到不同的装配构型，可以改变用其装配的并联机构的自由度，由此产生两类新型的并联变胞机构：一类是机构的各个支链中都有rT铰，该铰链的不同构型可以改变各支链对运动平台的约束或整个支链组的组合形式而改变机构的自由度状态，3PS和3C属于前者，通过调节rT铰到不同构型可以使其支链产生或消失局部自由度，从而减少或增加支链对运动平台的约束，使得并联变胞机构3PS和3C分别具有自由度从3变到6和从1变到6的能力；3P属于改变支链组组合形式的机构，其rT铰的不同构型将改变整个支链组的几何约束组合，使得并联变胞机构3P可以有三转动、三平动或三平移(来源：ABCded9de论文网www.abclunwen.com)一转动的自由度形式。
