不能使用

However, asthere was no illumination of the graticule, the sight could not beused at night.

因为分划没有照明装置，所以不能在夜间使用。

Since inextensible reinforcements do not stretch under design loading, they are the preferred MSE reinforcement type for highway structures in general and for critical structures such as bridge abutments in particular, where deformation control is crucial to structural performance of both the superstructure and the abutment.5 Inextensible reinforcements have been used successfully in MSE bridge abutment structures for thirty-five years, while research is still underway trying to develop an extensible

由于不可拉伸的加筋体在设计承载下不能拉伸变形，因此它们一般是公路结构，尤其是桥肩等重要结构中的首选材料，因为在这些结构中，变形控制对上层建筑和桥肩中性能表现是很关键的因素。不可拉伸加筋体在加筋土桥肩结构中已经成功的使用了35年，与此同时，研究能够在桥肩应用中性能有保证的可拉伸加筋体的工作正在进行中。

The Topcon KR-8100 automatic keratometry and the TMS-4 comeal topography can not be considered as interchangeable.

KR-8100自动角膜曲率计与TMS-4角膜地形图两种测量方法在临床上不能替代使用。

With the development of technology, the one dimension barcode can no longer meet the social needs because of its limitary information capacity and dependence on data-base, so the various 2-D barcodes come into use and generalization among which the PDF417 barcode is most widely used.

随着科技的发展，一维条码由于受到信息容量的限制和使用时对数据库的依赖，在很多场合已不能满足需要，于是二维条码得到推广和使用。在众多二维条码中，PDF417条码的应用最为广泛。

The component elements of the medical universitys core competence, withits localness, vagueness, timeliness and rigidity, decide that we cannot simplyuse the method of mathematical modeling, moreover, we must take the methodof index system to comprehensively assess it.

医科大学核心竞争力的构成要素，以及它的局部性、模糊性、时间性和刚性，决定了不能简单地使用数学模型法，而必须采用指标体系法对它进行综合评价。

Therefore many matirials with very good performance but very poor machinability are not rationally used.

许多具有十分优良性能的材料，由于很难加工，而不能合理地使用。

a mandatory testing device to prevent drunk driving is proposed.it can mandatorily test whether and how much a driver or a sailor on watch drunk.only when the alcoholicity of the exhalation breathed out by the people tested is normal,small type or automobiles can startup,the person on watch of a large ship can register as working.otherwise,if the alcoholicity is overproof,small type ships or automobiles can't startup,and neither does the device allow the person on watch register as working and it can inform the captain via alarm.in this way,drunk driving problem can be solved effectively only by setting a simple device.

该装置具有强制检测机动车驾驶员和船舶值班人员饮酒状态的功能，当被测人员呼出的气体酒精含量正常时，机动车或者小型船舶可以启动，大型船舶的值班人员可以记录为值班；当被测人员呼出的气体酒精含量超标时，机动车或者小型船舶无法启动，大型船舶的值班人员则不能记录为值班，同时可以通过报警器通知船长。这样，仅通过安装使用这样一个简单的装置，就有效地解决了酒后驾驶机动车和船员酒后值班的问题。

Arguably, the sort of tacit knowing which helps people to metaphorize is in itself an authentic way of knowing.

一些事实和我们的实验都可以证明，那类不能明言的、含糊的认知，会帮助人们使用隐喻，其本身就是一种可靠的认识途径。

The chemical analysis of N, P and K in organic fertilizer is presented: sample is decomposed by sulfuric acid-hydrogen peroxide and prepared to be a solution. N can be determined by NC-2 model quick N analysis set, P by chinoline molybdic acid method and K by tetraphenylboron potassium, needless of spectral photometer and flame photometer, the method is available when the content of N, P or K is over 0.1% with desired accuracy and precision.

介绍用化学分析方法测定有机肥料氮、磷、钾的含量，即样品经硫酸-过氧化氢消化后，制备待测溶液，分取待测溶液用NC-2型快速定氮仪测定氮，用磷钼酸喹啉重量法测定磷，用四苯硼酸钾重量法测定钾，不需使用分光光度计和火焰光度计，适宜一般复混肥料厂采用，对含氮、磷、钾分别达0.1％以上的样品均可用本法测定，方法的准确度和精密度能满足生产的要求。

The article of the Mormonite doctrine which is the chief provocative to the antipathy which thus breaks through the ordinary restraints of religious tolerance, is its sanction of polygamy; which, though permitted to Mahomedans, and Hindoos, and Chinese, seems to excite unquenchable animosity when practised by persons who speak English, and profess to be a kind of Christians.

摩门教主义之所以激起这种冲破宗教宽容的通常约束而迸发出来的强烈反感，主要是因为它在条款中认可了一夫多妻制；这个婚姻制度虽为回教徒、印度人以及中国人所允许，但在使用英国语言和自认为基督教徒的人们行来则会激起不能压熄的深恶痛绝。

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。
