卵子能存活多久:请大虾帮我翻译一下好吗？叩谢了

关于贵司针对1067#合同所提出的77420.46美元的费用一说，我公司表示无法理解。
Speaking of what your company has mentioned about the expense of $77420.46 in Cntract 1067#, I find it very hard to accept what you have proposed to our company.
贵司在1月27日出示1067#合同所产生的空运费等一些费用的清单之前，未有任何涉及此方面费用书面的文字通知我公司.
Before January 27th - the date that your company brought forth Contract 1067# which stated all the cost for all the aerial transportation, our company didn't get any early text notice about this.
现在就任凭贵司一方意愿要求我公司支付此费用，这实属无理要求。
And now your company demands us to pay for these costs, I find this too sudden and hard to satisfy this need of yours.
假如说贵公司让其他工厂生产这个产品再出现质量问题导致索赔，难道还会要求我公司同样承担吗？
Well, if you've asked other companies to fabricate this product, and as a result came to quality problems in the products leading to further compensation, how can our company be responsible for what happened?
此合同在几个月前就已经出货，上述费用应该早有结论，为何至今才提及？
We have already met our production deadline a few months ago, all the costs should be already been brought to an end, but how come you're bringing up more expenses problems?
是不是贵公司早有预谋而设下的商业陷阱。
I'm wondering if this is a trap set beforehand.
目前贵公司单方提出1067#合同费用而将正常履行的1052#合同的货款扣留是违反商业道德的，同时，非我公司生产的产品所产生的一切费用，我公司决不会承担。
What you have proposed in Contract 1067# about holding back our money from Contract 1052# is not considered to be a fair-play in business. As well, I declare that our company would not be responsible for the cost of any production that is not manufactured by our company.
关于1052#合同，我公司早已经按照贵公司的要求履行完毕产品的出口以及相关事宜，请贵公司恪守信誉，在本月底前必须将货款60775.91汇给我公司。
Subjecting to Contract 1052#, our company has already performed and completed our production tasks according to our company regulations. In addition to that, I hope your company will keep to your words on mailing to us the 60775.71 dollars by the end of this month.
