难加工性

Nevertheless, its commercial application was limited due to its poor processibility and insolubility in the common organic solvent.

但是由於加工性不佳；且难溶於一般有机溶剂中，因此使其商业化的应用有所限制。

As more use is made of costly, difficult-to-machine alloys, the relative precision and dimensional uniformity of forged parts become more desirable.

随着昂贵的、难切削加工材料的更多使用，提高锻件的精度及尺寸均匀性等将更加必要。

Because of the complex nature of cutting operations, it is difficult to establish relationships that quantitatively define the machinability of a material.

因为剪切工序的复杂属性，所以很难建立定量地释义材料的可机加工性的关系。

Surface modified magnesium hydroxide particles were synthesized by one-step process using magnesium sulfate,ammonia liquor and sodium laurate as raw materials in alcohol-water system ac- cording to the spectra of FTIR,it was inferred that sodium laurate was bound on the surface of Mg_2 particles and an organic coat- ing layer also formed.

0引官Mg2是一种无机添加型无毒阻燃剂，具有阻燃、消烟、阻滴、填充等多重性能，与川3相比，具有高的热稳定性，高效促基材成炭作用和强除酸能力等特性，但也存在颗粒表面亲水疏油、易团聚、难分散、吸湿性强等缺点，导致材料加工成本增加和综合性能降低川。

There are many defects in rubber machining due to larger elasticity,lower heat conductivity and strength of rubber.

橡胶的回弹性大、导热性差、强度低，属于难加工非金属材料之一。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
