可逆的

Many of these neuropsychiatric effects are reversible, and there is a much lower risk of developing these problems if a patient with lupus only has joint and skin involvement, if the patient is ANA-negative or if the illness is a the result of a medication, which can be withdrawn.

这些神经的影响，许多是可逆的，而且是发展这些问题的风险要低得多，如果与狼疮病人只有关节和皮肤的参与，如果病人是全日空负或者如果疾病是一个药物的结果，可以撤回。

In this study, the model drug, TSB-9, is a poorly water-soluble mixture extracted from Garcinia hanburyi Hook. f.. Gambogic acid is one compound which was proved potent cytotoxicities against various cancer cell lines by irreversible arrest in G2/M phase of the cell cycle in Gamgoge.

中文摘要在本研究中我们所使用的模式药物为TSB-9，是一种萃取自藤黄中的混合物，其成分之一，Gambogic acid在许多的药理研究中被认为对於癌细胞细胞周期中的G2期以及M期会产生不可逆的中止，所以有抑制肿瘤增生的功效。

At Hcy/Au electrode, there were electrocatalytic responses of DA and E with ΔEp 57.5mV and 63.5mV, respectively. The standard rate constants k〓 were calculated as 2.1×10〓 cm s〓 and 1.6×10〓 cm s〓 corresponding to DA and E. The electron transfer number n〓=1 was achieved, which revealed that the 2e transfer of DA and E is not completed by one step at the electrode. Because AA also displayed electrocatalytic behavior at Hcy/Au electrode, DA and E can be determined in presence of AA.At Hcy/Au electrode, a pair of very stable and well-defined redox waves of Mb were obtained.

在Hcy/Au电极上分别得到多巴胺、肾上腺素的一对可逆的氧化还原波，求出两者的电极反应速率常数分别为2.2×10〓cm s〓和1.6×10〓cm s〓，推导出在两者的电极反应过程中均存在一个自由基并且它的形成决定了整个电极反应的速度；由于抗坏血酸在此电极上也具有电催化响应，可以在抗坏血酸存在下对多巴胺和肾上腺素进行测定。

He results show that the virus regained infectivity, and the tannins did not direct viricidal effect. Tannins extracted from Polygonum perfoliatum or Archontophoenix alexandrae seeds showed strongly anti-TMV activities separately. TMV virions seems to be aggregated when TMV incubated with the tannins by electron microscope. It seems that TMV coat protein bind to the tannins based on PAGE. Tannins did not reduce infectivity when applied either before or after TMV inoculation. It is proposed that tannins extracted from the 11 species inhibited TMV by binding with TMV coat protein to interfere with recognition site essential for viral coat protein. Tannins extracted from Euphorbia hirta, P. perfoliatum, P. cuspidatum reduce infectivity when applied immediately in N.

MV分别与这11种植物单宁混合后，通过透析除去单宁后，可恢复大部分侵染力，表明单宁对病毒粒体并无直接毒害作用；TMV与杠板归和假槟榔种子中提取的单宁分别混合后，电镜下观察粒体呈现明显的聚集现象；TMV外壳蛋白分别与这两种植物单宁混合后，聚丙烯酰胺凝胶电泳中CP泳带滞后；单宁在病毒接种前施用未降低TMV对叶片的侵染能力；这些结果表明植物单宁对TMV抑制作用可能是单宁与TMV-CP结合影响病毒对叶片侵染位点的识别而降低TMV侵染性，而这种结合是可逆的。

When exterior factors such as the addition of electrolyte to colloids lead to the formation of lower symmetry aggregates such as trimers and tetramers, HRS signal is enhanced, but it is required that the aggregation of particles is compact and irreversible.

当外界因素导致的胶体中形成低对称性的粒子聚集体时，对HRS信号有增强作用，但要求粒子间的聚集是紧密的和不可逆的。

In comparison with the sample directly sintered at 650 ℃＜TN, an interesting, irreversible transformation in the crystal structure of the MgB2 phase is observed with the sample going through the stages of initial sintering at 750 ℃, then re-sintering at 650 ℃ in an Mg-rich environment after the processes of regrinding and pressing.

把直接在650 ℃＜T N，烧结的样品与先在750 ℃下烧结，之后又再次重磨和处理后，并于富镁的环境中在650 ℃下再烧结处理的样品相比较，观察到了MgB2的不可逆的晶体结构转变。

Along with the study of melanogenesls modulated mechanism continues deeply, the study of topical depigmenting agents get greatyl progressed, to find an effective, safe, reversible depigmenting agents become possibles. Some well-know depigmenting agents ramification and new natural product have shown widely development prospect.

随著人们对黑素生成调控机制研究的不断深入，外用脱色剂的研究越来越深入，寻找一种高效、安全、可逆的脱色剂成为可能，一些已知脱色剂的衍生物及许多新的天然产物表现出广阔的发展前景。

The major concern during laser irradiation of teeth is the high potential of tissue overheating resulting high temperatures that can spread in toward the dentin,causing irreversible damage to cells presented in the pulp chamber and leading to cell death,so the related laser irradiation parameters should be controlled strictly.

激光辐照牙齿时所产生的温升容易引起牙髓细胞不可逆的损伤，导致牙髓细胞坏死，因此必须对相关的激光参数加以控制。建立了激光与牙齿相互作用的热传输模型，利用Crank-N icolson有限差分法数值模拟了不同Nd∶YAG激光参数照射下牙齿表面及内部的温度场的分布。

The single thin sheet has a feature that its temperature decreases quickly and is difficult to maintain uniformity , thus using the reversible rolling to roll thin sheet by common mill was not able to be successfully because of the flatness deformation of roll.

单一薄板具有的特征是：它的温度下降得非常快，而且温度很难保持均匀，因此用普通的轧机采用可逆的方法轧制薄带是不可能成功的，因为轧制时平面要产生变形。

After a tooth is extracted, due to the lack of occlusive stimulation, the absorption of the remains of alveolar ridge shows an irreversible process, due to the imbalance of the bone formation.

牙齿拔除后，由于缺乏正常咬合力的生理性刺激，剩余牙槽嵴的吸收表现为一个持续、不可逆的过程，这是由于骨形成与吸收的不平衡造成的。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
