Russian term or phrase: "зацепленная" система уравнений
Сложность решения системы (1) заключается в том, что она является "зацепленной" относительно неизвестных функций Wm, Xm, т.е. все неизвестные функции входят в каждое из m+1 уравнений данной системы.

и дальше по тексту

После исключения из (1) функции Wm получим независимую систему уравнений относительно Xm. Таким образом достигается "расцепление" системы (1) на известную классическую относительно Wкл и систему относительно исеомой функции Xmi.

concatenated/coupled
Explanation:
В принципе оба термина применяются. Я бы выбрал второй - тогда расцепление (не могу согласиться с Верой - именно РасЦепление) будет uncoupling

constrained system of equations/system of equations with binding constraints (a wild guess)


Explanation:

A completely wild guess:)

Constrained Nonlinear Systems

Mathematically, a Constrained Nonlinear System (CNS) model looks like:


find x

F(x) = 0
subject to L < x < U
G(x) < b

where F and x are of equal dimension and the variables x are continuous. The (possibly empty) constraints L < x < U are not intended to be binding at the
solution, but instead are included to constrain the solution to a particular domain or to avoid regions where F(x) is undefined. The (possibly empty) constraints
G(x) < b are intended for the same purpose and are silently converted to equations with bounded slacks.

The CNS model is a generalization of the square system of equations F(x) = 0. There are a number of advantages to using the CNS model type (compared to
solving as an NLP with a dummy objective, say), including:

A check by GAMS that the model is really square,
solution/model diagnostics by the solver (e.g. singular at solution, locally unique solution), and
potential improvement in solution times, by taking better advantage of the model properties.

For information on CNS solvers that can be used through GAMS see the Solver/Model type Matrix.

"Anchored" system of equations


Explanation:
Дмитрий, я еще вчера послала ответ, но из-за каких-то фокусов сети он не прошел. Во всяком случае, я его не вижу.
К сожалению, потерялись и все примеры.
А сейчас мне некогда их снова искать.
Так что - либо поверьте мне на слово, либо подождите до сегодняшнего вечера.

Как надоели эти неполадки сетевые, кто б знал!

Мое предположение насчет расщепления - действительно ошибочное. Я его стерла.

Coupled


Explanation:
Я посмотрела сейчас в русских текстах - какие системы там называются зацепленными?
Таких систем я не нашла. Но нашла кучу "систем зацепленных/зацепляющихся уравнений". И такие уравнения действительно называются coupled, как пишет выше коллега bpz2001. Я привожу ниже все нужные ссылки, и Вы даже увидите, что системы из этих уравнений иногда тоже называют coupled systems.
Но у меня большое сомнение, что в Вашем контексте именно это имеется в виду. Во-первых, контекст не тот, а во-вторых, Вы сами говорите, что это слово стоит в кавычках, намекая тем самым на ненормативность употребления термина.
Итак, я Вам даю здесь все про термин Coupled, но сама продолжаю поиски тех ссылок про слово anchored, которые потерялись.

Как Вы видите, бывают даже цепочки (chains) из зацепленных уравнений:

Хотя - не знаю - вот нашлась одна \"зацепляющаяся система\", и вроде контекст почти как у Вас:

Я выяснила, что так называемые обобщенные уравнения Орнштейна-Цернике - это тоже \"зацепленная\" (coupled) система, но у нее есть специальное название : Replica system, ROZ equations. А \"зацеплением\", похоже, называют просто парную корреляцию (нет времени вчитываться как следует).
