必须的

We have examples of polyandry in which the wife has several husbands, who are not necessarily relatives; and very many examples of polyandry in which the husbands are all brothers.

我们有这样的一妻多夫的例子：妻子拥有几个并没有必须的的亲戚关系的丈夫；还有很多这样的例子：丈夫们全部是兄弟。

These data are consistent with the hypothesis that the nonmnemonic executive control processes that can contribute to working memory function are primarily prefrontal cortex-mediated whereas mnemonic processes necessary for working memory storage are primarily posteriorly mediated.

这些数据与下面这一假说是一致的，即有助於工作记忆功能的非记忆执行控制程序主要是前额皮质介导的，而工作记忆储存必须的记忆程序主要是后介导的。

After the calculation, the physician can read the numbers of pulses that would be required for this ablation, and the sizes of the various pulses created with various spot scanning ,next ,the surgeon is able to utilize the star s4 excimer laser to create a prevue lens with this calculated ablation so that the patient can subjectively assess the vision quality benefits of this particular correction.

在进行计算以后，医师能读取切削手术必须的脉冲数量，并且由变量光斑扫描所带来的不同脉冲的大小，然后，外科医生能运用VISX STAR s4准分子激光子童打制虚拟角膜镜片，这样医生可以主观地评估这一特定的矫正手术的视觉质量的优越性。

Nidulans had a phenotype of cytokinesis defect. Sequence analysis showed that SEPH is 42% identical to the serine–threonine kinase Cdc7p from fission yeast. Deletion of sepH resulted in a viable strain that failed to septate at any temperature. This is the first direct evidence for the existence of a functional pathway like SIN in A.

在构巢曲霉中，温度敏感型菌株筛选发现的SEPH与裂殖酵母SIN信号中的丝-苏氨酸激酶Cdc7p具有42%的同源性，它可能是胞质分裂早期所必须的组分之一，当sepH 缺失时，会导致细胞死亡，这也直接证明了构巢曲霉可能也存在和SIN信号相类似的胞质分裂调节途径。

With today's home theatre systems, high density residential areas and noise pollution, effective sound control is a must.

由于家庭影院系统的普及，住宅区的高度密集和噪音的污染，有效的声音控制是必须的。

There are regular shortages of beef, sugar, corn, eggs, oil, chicken and sometimes coffee.

这就是典型的改良主义的矛盾。关键的问题是什么纲领和组织是必须的以解决阶级利益的冲突。
