使循环

Using real-valued decomposition technique, Unitary Cyclic root-MUSIC algorithm without spectral search was proposed for multipath environment of mobile communication, by reconstructing the data model of the cyclic covariance matrix with Hermitian property, which has a better performance in the presence of multipath propagation and substantially reduces the computational complexity.

通过构造了循环自相关矩阵的数据模型，使其具有厄尔米特特性，提出了一种基于实值分解技术的循环root-MUSIC算法，无需空间谱搜索，较好地解决了多径传播环境中信号高度相关问题，极大地降低了计算量。

The oil-quenching tank uses the steel plate structure, has the square shape, the rectangle, the circular, in the fuel tank the installment has the electric heating tube, outside the trough the installment has the oil pump, the stainless steel disc heat interchanger, the automatic oil constant temperaturecontrols the warm cabinet, its principle of work: When the work piece enters fuel tank quenching to cause frequently the oil temperature elevates, the oil pump starts to work, sucks in the stainless steel disc heat interchanger fuel tank's in high temperature oil, this time cools the circulating waterto put through automatically, carries on the heat transfer through disc heat interchanger's multi-layer stainless steel plate trough, causes the quenching oil which the process cools to return to the oil-quenching tank again, so moves back and forth the circulation, achieves the fuel tank to decreasetemperature the goal.

The recirculating cooling water system has blown down with definite quantity termly,or reduced its nephelometer,PH value,alkalinity,CODMn and anaerobe number,the system various indexes tends to be normal.

循环冷却水系统定期定量排污，或使其浊度、pH值、碱度、CODMn及异氧菌数目下降，系统各项指标趋于正常，彻底解决循环冷却水系统产生大量泡沫的问题。

For the thrashing due to true sharing of data, we thoroughly study the relationship between array element accesses and loop indices of a nested loop, present a complete set of ideas, theories, and methods with which the staggering relation and the compacting relation between the threads of the nested loop (either with a single linear function or with multiple linear functions) can be determined at compile-time, and accordingly the nested loop (either perfectly nested or imperfectly nested) can be restructured to avoid the thrashing problem.

使用这套理论和方法，我们在编译时就可以确定出嵌套循环（含单线性函数或多线性函数，紧嵌套或非紧嵌套）各线索间的错位关系，一致错位关系和压缩关系，根据这种关系对嵌套循环进行重构可以使真共享抖动问题得到很好的解决。

Second, this dissertation analysises the performance of TA cyclospectrum estimation, and derives the averaged cyclic periodogram which can make the variance to be reduced.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
