Hardwiring is more efficient, but it takes time; for hardwiring to work, the stress must remain constant over a long period.

硬连线是最有效的，但那需要时间；为了使硬连线起作用，压力必须在相当长的时间内保持不断。

In order to optimize performances of shunt active power filter of harmonic compensation, attenuation ratio for switching ripple, stability and power losses, an improved LCL filter topology was presented based on the analysis of the frequency characteristics of the LCL filter, in which a switching-ripple shunt branch and a series-inductor were adopted to the damping resistor to reduce the power losses dramatically.

为了使并联有源滤波器谐波电流补偿性能、开关纹波衰减率、系统稳定性和功率损耗等方面性能得到系统的折中和优化，提出了一种改进型LCL滤波器拓扑，该结构充分利用了LCL滤波器的频率特性，在阻尼电阻两端引入开关纹波谐振分流支路，同时在阻尼电阻上串联一小电感，有效的减少了阻尼电阻的损耗而不改变系统的静态和动态性能。

Homothallic species may produce distinctly different sizes of gametes that can fuse with each other and are thus effectively hermaphrodite.

The using of the technologies of DOA in the orientation estimating of interference is discussed, then an evolutive ESPRIT algorithm is put forward which avoids the eigendecomposition and is easily achieved. To the MUSIC algorithm, an easy eigendecomposition algorithm for Hermitian matrix is presented. It breaks away form the complex matrix decomposition such as QR algorithm. Basing on the whole matrix, the algorithm makes use of the multiplication operation of matrix and vector, which attains simpleness and is fit for DSP. In the field of DOA estimating of correlation interferences, spatial smoothing algorithm consumes too many array units.

讨论了DOA技术在干扰源方位估计中的应用，提出了一种ESPRIT演变算法，该算法避开了特征值分解，实现简便；在MUSIC算法的实现中提出了一个Hermitian矩阵特征值分解算法，该算法摆脱了复杂矩阵分解，从矩阵整体出发，主要的运算是矩阵与矢量的乘运算，算法简单，非常适合DSP芯片实现；在相关源的DOA估计中，空间平滑技术使阵元的损失非常大，本文提出了一种进一步降低阵元消耗的平滑技术—随机空间增益法，其在运算量上的增加很小，但对于相干源的去相关确是有效的。

In the author's opinion, the crops which has effectively challenged the orthodox system and the set principle in traditional societies proves the significance of growth. At the same time, the growth is also full of anxiety for the crops' hider.

在他们的写作中，作为对传统社会的正统体制和既定原则有效挑战的"身体"，对成长的意义作出了证明；同时成长也因身体真相的阻挡而显得焦虑重重，他们不得不期望以都市时尚中的身体行动来使自己得到缓冲。

When using it, the high pressure condition and the relief pressure condition can be charged by itself.

Sometimes very effective induction treatment may make it that much more difficult for the thoracic surgeon to dissect the hilum and mediastinum.

有时很 有效诱导治疗可能会使人们认为更为困难为胸外科医生解剖了门及纵隔。

These include a trio of main entrances that are each shaped differently, and which are accompanied by statues that were once coloured to make them more effective as Bible lessons for the hoi polloi.

这些措施包括三个主要入口，每一形状不同，它是伴随着雕像曾是颜色，使其更加有效的圣经教训的海民众。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
