For example, MacOS X uses UTF-8 while Windows uses a configurable encoding; on Windows, Python uses the name "mbcs" to refer to whatever the currently configured encoding is.

例如，MacOS X用户使用UTF-8，而Windows用户使用一个可配置的编码；在Windows系统上，Python用户使用"mbcs"来获取系统目前的编码。

You can use either type of encoding for form submissions, but at this time, file uploads can only be performed with the multipart encoding.

在表单提交时你可以使用任一种编码，但在目前上传的文件仅能表现为multipart编码。

For the partial products generation, the novel method of Booth encoding combined with partial products generating is put up, which can directly map the multiplicand and multiplicator to partition products without generating the BOOTH encoding results. For the optimization of Wallace tree adding, the series formulas of full-adder and 4-2 Compressor realization are introduced to guidance the selection. For the non-bias round, forwarding round disposal in Wallace tree method is brought forward to avoid the final multi-bit adder. Also, the idea of delay-oriented partition of the MAC frame is put up to achieve the perfect match with multi-pipeline DSP architecture.

The full-length cDNAs of rice and wheat S-adenosylmethionine decarboxylase gene were isolated and characterized. The rice SAMDC cDNA is 1560 bp in length, encoding a polypeptide of 398 amino acids, and the wheat SAMDC cDNA is 1351 bp in length, encoding a polypeptide of 392 amino acids. Both the rice and wheat SAMDC proteins contain the conserved proenzyme cleavage site and the PEST domains, which are commonly found in the SAMDC protein sequences of all eukaryotes.
