These edges profiles are also configured to inhibit redeposition of residue particulates on the top surfaces of the wafers during semiconductor processing steps.

还构造这些边缘轮廓以在半导体加工步骤期间抑制在晶片上表面上再淀积残存颗粒。

But the finite difference methods require that computational domain is regular, and usually people construct the difference scheme for one dimension and then extend it to two or three dimensions in a dimension by dimension fashion.

有限差分方法要求计算区域比较规则，而且人们往往是对一维方程构造差分格式，再用分裂方法将其推广到多维。

Fully considering the factors of structure, deposition, transforming system and Reservoir Forming Dynamics and so on, the paper thought that the reservoirs in Xiakou fracture zone belong to hydrocarbon remigration and secondary accumulation mode, the configuration relationship between the sands and faults is the main factor that affects hydrocarbon migration; reservoir gathers in the central upheaval zone belong to event hydrocarbon migration and accumulation mode, it can be divided into three styles, they are the fracture activity event mode, the volcanic activity event mode, he gravity flows event mode. The key factors of resulting in event reservoir are fault cyclicity and episodic characteristic.

充分考虑构造、沉积、输导体系和成藏动力等因素，分析认为：夏口断裂带油气藏聚集属于油气再运聚成藏模式，连通砂体与断层的配置是影响油气运移的主要因素；中央隆起带油气藏聚集属于油气事件成藏模式，划分为断裂活动事件成藏模式、火山活动事件成藏模式和重力流事件油气成藏模式三类，断层活动的旋回性和幕式性是诱发事件成藏的关键因素。

According to the input of sample set, a function set of multiresolution wavelet node was obtained and the output vectors of each node were computed.

摘 要：依据训练数据集，构造多分辨率的小波节点库，再根据输入给出小波节点的输出向量。

A new multiclass SVM algorithm based on binary tree was introduced on E-mail filtering. It could convert multiclass problem to binary classification by constructing binary tree. The idea of clustering first and classification later was adopted, and the largest similarity between testing sample and sub-category center and the separation measure of sub-categories were calculated, in oder to construct the optimal class hyperplane of decision-making nodes.

I thirstily hope to experience really spring in the air rural scenery, with Ping Ping again, but is not in the light total information structure spring mirage.

我多想真实经历春意盎然的田园风光，和萍萍再恋爱，而不是在光全息构造春天的幻景里。

Considering the behaviors of unbonded prestressed concrete beams and steel reinforced concrete columns, a kind of nonconforming beam-column element was constructed and the analysis precision was improved. Loading and reloading paths were introduced into the constitutive relationship of concrete. It is helpful to the analysis program to trace the full-range mechanical behavior of structures including the descending part and the hysterisis characteristic under cyclic loading.

考虑无粘结预应力混凝土梁、型钢混凝土柱等结构构件的受力特点，构造非协调梁柱单元，提高了分析精度；混凝土的本构关系中，引入卸载路径和再加载路径，使得分析程序可以追踪包括下降段在内的结构全过程力学行为，以及反复荷载下结构的滞回特性。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
