Moreover, combining with dynamic trajectory simulation of different kinds of aircraft with atmosphere perturbance models, a software package of radar signatures prediction and analysis is presented.

二、分析了活动部件周期调制特征产生机理和频谱结构特点，并通过建立通用仿真模型描述直升机旋翼，螺旋桨以及喷气引擎压缩叶片的动态电磁散射现象；针对活动部件周期调制，阐述了自相关特征提取和子波包特征空间变换的基本原理；并利用模糊模式比较完成基于空中目标活动部件周期调制特征的分类识别试验，给出识别结果。

It chooses injector\'s capacity of tolerance and the size of injector by the touch keyboard. It displays real time infliction axis direction, distortion distance, keep time, interior hydraulic pressure, separatory power and other performance, which can be print the result of measuring by machine.

并由触摸键进行选择注射器的公称容量，并在测试过程中显示装配施加的轴向力、扭矩，保持时间、内部水压、分离力，可测试注射器和注射针的漏液、漏气、分离力、旋开扭矩、易装配性、抗滑丝性、应力开裂等各项性能，可由机载打印机打印出测试结果。

The results show that the bioaccumulation coefficience in the aboveground of Scnecio vulgaris、Sonchus brachyotus、Znula Britannica、Artemisia scoparia、Artemisia annua、Peucedamum terebinthaceum and Polygonum bungeanum are more l respectively,and the concentration of Cd in the aboveground of plant is more than that in root,which possessed basic characteristics of hype...

结果表明：欧洲千里光、巨荬菜、欧亚旋覆花、猪毛蒿、黄花蒿、石防风和柳叶刺蓼 7种植物对 Cd的富集系数最大，且地上部 Cd的含量大于根部 Cd的含量，具备了重金属超富集植物的基本特征；植物地上部重金属含量与植物上部生物量的大小无关；以杂草为研究对象，有可能筛选出地上部重金属富集量大并且地上部生物量也高的超富集植物。

This method has been applied to fluvial reservoirs of lower Minghuazhen Formation of Gangdong oil field, including setting high resolution isochronal stratigraphic framework on the base of intermediate term stratal cycle and predicting the location and type of sand bodies based on their size derived.

应用该方法对比黄骅坳陷港东油田明化镇组下段部分河流相储集层，首先建立以中期地层旋回为基础的等时地层格架，再以微相类型相同为对比约束条件，然后根据确定的砂体大小预测出砂体的位置和类型。

A strain NK13 was screened for a certain extent asymmetric hydrolyze the rac-ketoprofen Chloroethyl ester and identified as Bacillus megaterium. For the preparation of gene libraries, a positive clones was obtained from the tributyrin flat. The sequence of this esterase gene had been analysised, and contained the whole ORF of an esterase gene with the length of 933bp.

以本实验室筛选出的一株具有不对称拆分消旋酮基布洛芬氯乙酯的菌株NK13为材料，经初步鉴定为巨大芽孢杆菌，通过构建其基因文库，从中筛选得到一阳性克隆重组子pUC-NK。

After administration of L-N〓-nitro-Arginine, a specific antagonist of NOS, it was found that the basal and stimulated NO release of blood vessels (aorta, internal carotid, renal and mensenteric artery) was decreased further. The increase of coronary blood flow stimulated by Ach was also reduced further, while the platelet aggregation degree and erythrocyte aggregation index increased significantly. Pathological examination indicated that aortic endothelium was destroyed, the blood vessels in cerebral, cardiac and renal tissues were hypertrophied further and some were almost occluded. The above fin dings resulted in SHR feeded with L-NNA having high incidence of stroke rate and high degree of renal cirrhosis when compared to control SHR. The infarct and hemorrhagic focuci in cerebral tissues, infarct focuci in cardiac tissues, atrophy and hyalinedegeneration of renal glomeruli and degeneration even necrosis of renal tubuli in renal tissues were al so found. The increase ratio of brain and heart to body weight and decrease ratio of kidney to body wei ght further demonstrated that the cerebral, cardiac and renal injuries were aggravated.

在上述结果的基础上进一步给予SHR NOS特异性拮抗剂左旋亚硝基精氨酸后，血管(胸主、颈内、肾及肠系膜动脉)NO基础释放及激动剂刺激释放进一步减少，Ach刺激冠脉流量的增加和胸主动脉内膜NOS活性也进一步减少，血小板聚集程度及红细胞聚集指数显著上升，病理切片显示胸主动脉内皮细胞破坏明显，脑心肾组织内的血管进一步增厚甚至几乎阻塞，导致饲L-NNA的SHR缺血性及出血性脑卒中发生率显著高于对照SHR，脑体重比显著升高；心肌内出现明显的缺血梗塞疤痕灶，心体重比显著升高；肾小球明显萎缩、玻璃样变性，肾小管也变性甚至坏死，使肾硬化程度显著增加呈颗粒性固缩肾，肾体重比也显著减少。

This was fine for the British. By 1943 they had developed a replacement unit that could be installed simply by unscrewing four mounting bolts, pulling out the old unit, and installing the new unit.

对英国人来说它们是好坦克。1943年他们研制了一套替换组件，仅仅旋掉四个固定螺栓，拉出旧的组件就可以安装新的组件。

PLIC3D algorithm, a 3-dimensional VOF method with piecewise linear interface construction and split and unsplit propagation, is specially devised for better solution to free surfaces. Particularly split PLIC3D is applied in numerically modeling draining from bottom of a cylindrical vessel and water-exit of a revolution body, from which evolutions of free surfaces are mainly illustrated.

重点在直角坐标系中推导了用斜面构造自由界面，使用分裂和不分裂推进的三维VOF方法：PLIC3D，以改善自由面求解精度；并用分裂的PLIC3D算法模拟了三维的柱形容器泄漏和旋成体出水问题，结果主要显示了它们的液面运动变化。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
