不精密

Life is not an exact science, it is an art.

生活不是一门精密科学，它是一门艺术。

What they prove is that he did not possess that sense of historical exactitude which we now demand from the historian.

他们证明，是因为他不具备这个意义上的历史精密我们现在的需求历史学家。

The constant current coulometry as a primary method is recognized in international. Based on Faraday's law of electrolysis, it has been successfully used to determine purity of arsenic trioxide. The measuring results depend directly on the reliability of measuring physical quantities and fundamental constants expressed in SI units, and do not need a reference material for comparison.

高精密库仑滴定法是国际上公认的基准测量方法，该方法根据法拉第电解定律，通过质量、电阻、电动势、时间等基本物理量及法拉第常数来进行三氧化二砷纯度的测定，直接溯源到国际SI单位，不需要用标准物质进行比对。

The winding film, also called as elastic film, is a kind of soft polyethylene plastic film with good transparency, elasticity and intensity. In case of non-heating it, it can stretch in length and breadth. It can wrap the products of electrical household appliances, precision instrument, bicycle, motorcycle, top-grade furniture, etc with its own autohension and make them keep tension and unloosen for a long time.

缠绕膜生产设备生产的缠绕膜，是一种透明、富有弹性及强度的柔软聚乙烯塑料薄膜，它可在不加热的情况下，进行纵横双向冷拉伸，依靠它本身自粘性对家用电器、精密仪器、自行车、摩托车、高档家俱等包装，并可使货物长期保持张力而不致于松散。

Concrete was not a barrier, as she would be placing five highly sophisticated bugs inconspicuously in the conference rooms.

具体是不是一个障碍，因为她将配售5高度精密的错误inconspicuously在会议室。

Kerf roughness and quality control of laser precision cutting［J］.

TO eliminate error caused by the rod being tipped forward or backward, the rodman waves the rod ,or tilts it slowly forward and backward,and the leveler takes the least reading. For less precise leveling, as when rod rcadings for ground points are determined to the nearest 0.1 ft, usually less care is exercised in keeping the bubble centered and the rod vertical,and the observations are no checked.

为了消除所造成的误差棒正在向前或向后，在罗德曼波杆，或倾斜，慢慢前进，后退，和矫直需要至少不到精密水准，如棒为确定地面点到最近的0.1英尺，通常较少照顾行使维持泡沫中心和棒垂直，没有检查。

Standard precision resistors produced using EVANOHM alloy R display a maximum drift of 5 ppm per year for 15 years (for resistance from 1 ohm to 1 megohm); secondary standards display drifts from ± 6 to ±23 ppm per year over a 14 year period.

使用 EVANOHM alloy R 材料制造的标准精密电阻器在15年里都具有不超过5ppm/年的流失率（电阻从1欧到1兆欧）；二级电阻器在14年内也保有± 6至±23 ppm/年的流失率。

Alleged more haste,less speed, seem to make a product of accurate science and technology.

所谓欲速则不达，就似乎制造一个精密的科技产品。

Although not a precision instrument, the ohmmeter is a useful device for rapid measurement of resistance.

欧姆计是一种很有用的仪表，可以用来迅速地测量电阻，尽管它不是一种精密仪表。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
