The homeotic gene not only plays a role in the tegulation of cell ar- rangement in plant s organ, but also is the base of the floral meristem identity, inflores- cence meristem identity and floral organ identity.

植物由营养状态转入生殖状态是发育过程中的重要一步，其转变过程受遗传固子及环境的双重控制，光周期与温度是影响开花诱导的主要环境固子，而植物的同源异型基因参与植物器官内细胞排列方式形成的调拉过程，是拉制花分生组织特异性、花序分生组织特异性和花器官特异性的基础。

It is concluded that Holonic Manufacturing Systems adopt a slacked dynamic hierarchy and that Holonic Manufacturing Systems are still in a phase of research and far from wide application in industries.

整子制造系统采用了一种松弛的动态递阶控制结构。目前整子制造系统仍然处于对&下一代制造模式&的研究阶段，离实际应用还有一定的距离。

A new lower-resolution subzonal wave-front corrector can be approximated by subdividing the wave-front corrector′s aperture into multiple subzones, all actuators associated with each subzone being treated as a whole controlling element.

将波前校正器光学孔径分成多块子区域，每块子区域对应着的所有驱动器作为一个整体控制单元，从形式上可以得到一个空间分辨率较低的分区域波前校正器。

"To be uncontrollable, as a horse is when it clenches its teeth on the bit; to cast off or refuse restraint."

难以控制，如上嚼子的马紧咬着嚼子；释放或摆脱束缚。

The arc array transmitter is composed of many ceramic flexural vibrators which are arranged in an annulus. Directional radiation is realized by controlling the vibrating phase of each vibrator.

声波测井圆弧阵发射换能器由多个压电振子沿着圆周排列，通过控制各个振子的激励时间可以实现向某个方位方向的声波辐射。

Results show that the small vibration of this ideal model is non-simple harmonic,and the period of vibration in x direction and y direction are inverse ratio to the amplitude inverse ratio to the amplitude respectively,but influenced a little by them,and the waveform that coul.

本文应用拉格朗日方程方法研究了理想对称四弹性振子做二维运动的变化规律，得到其微小振动的控制方程，用数值解法求解出了振动方程，得到了振子运动的时程响应和轨迹图样。

Another form of translational control occurs when translation of one cistron requires changes in secondary structure that depend on translation of a preceding cistron.

当一顺反子的翻译要求二级结构的改变，而该二级结构取决于前一顺反子的翻译时，另一种形式的翻译控制发生了。

A gene can be defined as the smallest hereditary unit capable either of recombination or of mutation. Alternatively it may be described as a unit of function, a CISTRON, which may be much larger than a unit of recombination or mutation, and controls the synthesis of a single polypeptide or a messenger RNA molecule whose genetic code is sontained within the gene.

基因是重组和突变的最小遗传单位，也可以被描述为一种功能单位———顺反子，顺反子可能比重组和突变单位大的多，它控制单个多肽的合成或合成含有遗传信息的信使 RNA 密码子。

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。
