The typical molten pool of high energy beam welding is in nailhead shape with large aspect ratio. In order to simulate it more precisely, a new heat source model, Rotary-Gauss body heat source model, is established.

为准确地模拟出大深宽比的"钉头"状高能束熔池形状，提出了新的旋转Gauss曲面体热源模型，并进行了实际的数值模拟与测量试验。

SMA staining was positive in basophilous small blocks, spindle or irregular cell cluster. Of the 218 cases, 56 cases had smooth muscle. S-100 staining demonstrated that neurofilament protein and adipocytes were positive. Of the 218 cases, 44 cases had adipose tissue.

平滑肌肌动蛋白染色显示嗜碱性的小团状、梭形或不规则形的细胞束呈阳性反应，证明为平滑肌，218例中56例显示了平滑肌的存在。S-100染色神经纤维丝及脂肪细胞均呈阳性反应，218例中44例有脂肪组织。

The results show that the conformation of copolymer molecules is totally different from that of carboxy methyl cellulose because of the introduction of the surface active macromonomers.

结果表明，共聚物在水溶液中的形态完全不同于羧甲基纤维素分子，亲水疏水链段的引入，使共聚物分子聚集形成了以疏水链段为核心的棍状胶束结构。

Based on membrane extraction and helical tube technique, the mass transfer performance of some membrane modules with a different helically wound hollow-fibre was studied with the system of 30%TBP-water and phenol as the solute. The effects of two phase flow rates, geometry of the membranes on mass transfer coefficients were investigated.

The experiment was performed at the Asterix IV iodine laser with a prepulse 5 ns before the main pulse. Under optimum focusing conditions for main pulse and prepulse the X-ray laser beam splits into two beamlets along the target surface at its output end of the 2.5 cm long plasma column. The splitting was still observed when the prepulse alone was defocused.

实验发现在抽运激光主、预脉冲最佳聚焦条件下， X射线激光束在2.5 cm长的线状等离子体输出端沿靶面方向分裂成两束；在抽运预脉冲单独散焦条件下，仍然观察到这一分裂现象；但是当抽运主、预脉冲同时散焦时，这一分裂现象逐渐消失并获得了半宽度只有40 μm的非常窄的近场像。

The lotus fiber,showing ribbon spiral revolving structure vertically,has clearly imperceptible cross striation,and is bundle fiber composed of many monofils.

莲纤维的纵向呈带状螺旋状转曲，有清晰的细微横纹，并且是由多根单丝纤维缔合组成的束纤维。

Time (3Xrpm) turning table speed. In addition, while the teeth of the tri-cone bit interact with the formation, the drillstring will generate tiny axial vibration. As the vibration is symphonious to the tri-spine well bottom, the vibration signal exhibits amplitude modulation character. This character had been verified by in-site measurement data and numerical simulation.

另外，三牙轮钻头与地层作用破岩时牙轮牙齿产生啮合振动，由于三脊状井底对啮合振动进行幅度调制形成调幅信号，根据调幅信号的频率特征，振动信号在频域表现为具有一定边带的一束谱线，它是钻头工作正常的&健康信号&。
