って部分 meaning and sentence translation


Two people are discussing countermeasures for some new technology (Tech A) and
what should be researched, issues and like. There is a lot of technobabble
basically. The last possible solution is nowhere near ready and then the
following exchange happens:

> M: Technology Bをヒントにした / 機構そのものはいい感じなんだけどねぇ
>
> H: 拡散してしまうなら / 高密度に圧縮した弾なり装置なりを利用すればいいって部分ですね。 ただ…

Technology B is something they got examples of recently and have been studying
it. It's not what the countermeasures are for. Also I have used / to note word
bubble splits, since it's a manga conversation and hence it has no punctuation
(what fun).

The main problem I have with is the last line. The first one I think I have
figured out, although I would appreciate being notified if I made some big
mistake there.

> M: I do feel positive about the mechanism the Technology B hinted at.
>
> H: If it proliferates, it’s the part where we should use the devices or high
> density compressed bullets. However…

The second one is problematic for couple of reasons. First, the 拡散してしまうなら bit,
I'm not sure what it refers to. I think it's a conditional "If Tech A
proliferates/spreads".

The next problem I have is the って部分 bit, which is kinda strange. The only way
I can figure it working is that M and H have had a conversation about
possibilities of promising Technology B before and she is now referring to one
part of that promise that M told H about.

What is weird to me is using a should (if we use it would be good) quote to
describe a part? Which is why I'd like some input on what others think is the
meaning of these lines.




I believe you've understood the sentence correctly, and also understand the
basics of the って grammar.

The って can mean multiple things including "speaking/talking of", but I think
in this case it's a contraction of `という`.

> 高密度に圧縮した弾なり装置なりを利用すればいい **という** 部分ですね。

Like this, it would translate like "the part where (described as) we should
use the devices or high density..."
