शैडोइंग अभ्यास: What is IMC (Intermetallic Compounds) part II? The different between IMC, alloy, eutectic - वीडियो के साथ अंग्रेजी बोलना सीखें
पाठ बनाया जा रहा है...
1
Hello everyone, today I would like to delve what is IMC again.
2
The Intermetallic Compounds Part 2 Please note that this presentation is a personal sharing,
3
and the content might not be 100% accurate.
4
For more information, you can visit website of mpe.researchmfg.com So,
5
what is IMC, alloy and eutectic?
6
What are the difference between them?
7
Alloy is a term we encounter often in PCB manufacturing.
8
For instance, SAC305 is an alloy comprising 96.5% tin,
9
3% silver, and 0.5% copper.
10
But does IMC also fall under the category of an alloy?
11
In myopian, IMC isn't truly an alloy.
12
Neither is it classified as a eutectic.
13
Furthermore, IMC isn't a pure metal element due to its distinct physical and chemical characteristics that differ from traditional alloys and eutectics.
14
Interestingly, IMC is often grouped as an alloy, sparking the question of why this classification is used.
15
To distinguish between IMC, alloys, and eutectics, let's employ an analogy.
16
Imagine boys and girls as different metal elements.
17
Alloys are like mixing boys and girls in the same classroom where they coexist evenly.
18
When the boys and girls share an affinity and form eutectic points,
19
it's referred to as eutectic.
20
On the other hand, IMC is akin to a child born from the union of these boys and girls.
21
IMC emerges from a chemical reaction.
22
Please note that while this metaphor may not be perfectly precise, it's a concept and a way to understand the subject better.
23
This comparison is purely illustrative, but it helps to highlight the distinctions between IMC, alloys, and eutectics.
24
Moving forward, we'll continue exploring this subject in more detail.
25
Thank you for joining me for this second video on IMC.
26
In our next session, I'll provide a more comprehensive introduction to alloys and eutectics.
27
Until next time, take care and goodbye.
28
Thank you.

इस पाठ की शब्दावली और बोलने के सुझाव
इस वीडियो में शैडोइंग के लिए 28 वाक्य और 300 शब्द हैं। बोला गया हिस्सा 3:10 लंबा है। वक्ता धीरे बोलता है, लगभग 95 शब्द प्रति मिनट, इसलिए हर ध्वनि की नकल करने का समय मिलता है। केवल 71% शब्द अंग्रेज़ी के 3,000 सबसे आम शब्दों में से हैं, इसलिए शब्दावली कठिन है।
इस वीडियो की मुख्य शब्दावली
वीडियो के 14 कम प्रचलित शब्द, उच्चारण और अर्थ के साथ:

इस वीडियो से अभ्यास कैसे करें
- पहले बिना बोले पूरा वीडियो एक बार सुनें और जो शब्द नहीं आते उन्हें लिख लें।
- सामान्य गति पर एक-एक वाक्य की शैडोइंग करें और हर वाक्य तब तक दोहराएँ जब तक आपकी लय वक्ता से न मिल जाए।
- अपनी आवाज़ रिकॉर्ड करें और मूल से तुलना करें, ख़ासकर alloy, element, comprehensive जैसे शब्दों पर ध्यान दें।
शैडोइंग तकनीक क्या है?
शैडोइंग (Shadowing) एक विज्ञान-समर्थित भाषा सीखने की तकनीक है जो मूल रूप से पेशेवर दुभाषिया प्रशिक्षण के लिए विकसित की गई थी। विधि सरल लेकिन शक्तिशाली है: आप मूल अंग्रेज़ी ऑडियो सुनते हैं और तुरंत इसे ज़ोर से दोहराते हैं — जैसे वक्ता की छाया 1-2 सेकंड की देरी से। शोध से पता चलता है कि यह उच्चारण सटीकता, स्वर, लय, जुड़ी हुई ध्वनियाँ, सुनने की समझ और बोलने की प्रवाहशीलता में काफ़ी सुधार करता है।
