If the excitation amplitude is constant and the excitation frequency is close to 3-times resonance frequency, the effect of the 3-times superharmonic resonance on the system response increases greatly.

当激励幅值不变、激励频率逐渐接近3倍超谐共振频率点时，3倍超谐振动成分对系统响应的影响逐渐增加，这表明立方非线性对系统的调节作用越来越强。

Objective: Effects of a single period of mechanical strain on gene expression patterns of two osteogenic transcription factors, Ets1 and Cbfa1, in rat calvarial sutural osteoblast-like cells were studied in this study to elucidate the molecular mechanism of suture distraction.

结果：Ets1和Cbfa1的mRNA水平分别在机械张应力作用后6 h及12 h内显著增高，随后，mRNA水平逐渐恢复到对照组水平，Ets1先于Cbfa1表达，在加力后表达立即升高，并在0.5h达到最高水平，而Cbfa1则首先经历一个短暂的潜伏期，后表达逐渐升高，在6 h达到最高水平，Cbfa1的最高表达水平约为Ets1的2.58倍。

The storm is beginning to taper off now.

When mixed into the same carbon fiber quantity is 1.0%, differ age material's AC impedance chart is discrepancy very much, along with to hydrate age's add, C-S-H gel isa great deal of form, the solution resistance at the concrete is gradually aggrandizement, the carbon fibre of here qua transmit electricity quality disperse would leading effect of conductance, along with the add of exterior load, the transmit electricity quality of concrete is almost nothing change, till breakage, resistance change rate tempestuousness add, and that the resistance change rate along with inside stress linearity add of corbon fibre concrete in elasticity phase, when near peak value load, resistance rate just gradually add, indicate the test sample would be about to breakage.

当碳纤维体积掺量同为1.0%时，不同龄期材料的交流阻抗谱相差很大，随着水化龄期的增长，C-S-H凝胶大量形成，水泥基材料中的溶液电阻逐渐增大，此时作为导电性分散相的碳纤维将起电导的主导作用。随着外部荷载的增加，基准水泥基材料的导电性几乎无变化，直到破坏时，电阻变化率剧烈增大，而碳纤维水泥基材料在弹性阶段其电阻变化率随内部应力线性增加，当接近峰值荷载时，电阻率才逐渐增大，预示试件即将破坏。

The analysis of TOC andδ13Corg benefits from Well Chao-73, indicating that they response well enough to the Cretaceous paleoenvironment and paleoclimate. During the sedimentary period of Quantou formation to Qingshankou formation in Songliao basin, the water tends to rise and becomes anoxic, and the deoxidized water leads to the organic matter massively preserved. The paleoclimate changes from torridity and aridity to warmth and humidity, with the temperature evidently descengded, then ascended in a litter range. The result is basically consistent with paleoclimate by the palynological analysis.

朝73井TOC、δ13Corg有机地球化学指标的分析结果表明，TOC、δ13Corg的变化对该沉积时期的古环境、古气候也有很好的响应，该沉积期湖水位不断上升，湖生生物逐渐发展并繁盛起来，水体含氧量减少，湖底有机质的保存环境逐渐变为强还原环境，大量有机质被埋藏并保存，而古气候在泉头组/青山口组界线上下由炎热干旱变得温暖湿润，气温有明显下降，但随后又有小幅的上升，与孢粉分析的古气候变化特征基本一致。

RESULTS: The BMD ratio of the lateral trochanter to the neck gradually reduced with age, whereas that of the medial trochanter to the neck gradually increased.

结果：外侧大转子至股骨颈的骨矿物质密度随年龄逐渐减少，而内侧外侧大转子至股骨颈的骨矿物质密度随年龄逐渐增加。

在他们争取真正的自由的奋斗中，在他们的胜利与失败之中，在未来的漫长岁月中，我看见这一时代的邪恶和前一时代的邪恶逐渐赎去自己的罪孽，并逐渐消失。

Results PCNA positive smooth muscle cells appeared 6 hours after transplantation, increased with time, and reached a peak at 1 to 2 weeks. After 2 weeks, PCNA positive SMC in the tunica media began to decline and recovered to the 6 hour level at 8 weeks after the operation.

结果 移植术后6h，吻合口处中膜即出现PCNA阳性平滑肌细胞，并随着时间推移逐渐增高，在1~2周左右达到高峰。2周后，中膜PCNA阳性SMC开始逐渐减少，于术后8周趋于平稳。

Accord- ing to the observation that the compounds were stable in low pH aqueous solution and their sta- bility decreased when pH increased, and they rapidly decomposed to form α-methylenecyclopen- tanones derivative when pH reached 6 to 7, we postulated that the compounds were unabsorbable in stomack (where pH1-3) and unstable in small intestine (where pH5-8). The decomposed product was indeed inactive.

对Ⅰ类化合物在稀溶液中的稳定性研究表明，低pH时化合物较稳定，随着pH值的升高稳定性逐渐降低，pH6~7时，化合物迅速分解成α-亚甲基环戊酮类化合物，由此而推测Ⅰ类化合物经口给药无效的原因为：它们在强酸性的胃中（pH1-3）呈离子状态，因而不易吸收，经胃的排空运动进入肠道后，随着pH逐渐升高（pH5-8）化合物迅速分解，而分解产物α-亚甲基环戊酮类化合物证明是无效的。

Positive tensile stress on iron undersurface relaxes to the inner of iron and negative tensile stress on iron undersurface concentrates on the side of iron as the temperature declining, so cracks easily appear at the site where positive and negative tensile stress cross.

在冷却过程中，铸铁下表面的拉应力逐渐向铸铁内部释放；同时，压应力逐渐向铸铁的两侧端面集中。因此在拉应力和压应力的交界处，容易产生裂纹。
