soil moisture
1) Water stored in soils.
2) One of the most important elements involved in pedological processes and plant growth. There are three basic forms:
a) water adhering in thin films by molecular attraction to the surface of soil particles and not available for plants is termed hygroscopic water.
b) Water forming thicker films and occupying the smaller pore spaces is termed capillary water. Since it is held against the force of gravity it is permanently available for plant growth and it is this type of soil water which contains plant nutrients in solution.
c) Water in excess of hygroscopic and capillary water is termed gravitational water, which is of a transitory nature because it flows away under the influence of gravity. When the excess has drained away the amount of water retained in the soil is termed its field capacity, when some of its pore spaces are still free of water.

3 contacteur à accrochage
запираемый контактор
Контактор, в котором запирающее приспособление не позволяет подвижным элементам вернуться в положение покоя, когда прекращается воздействие на механизм управления.
Примечания
1 Запор защелки и его расцепитель могут быть механическими, пневматическими и т. п.
2 Благодаря запору контактор фактически приобретает второе положение покоя и, в полном смысле этого определения, к контакторам не относится. Однако согласно области применения к конструкции запираемый контактор более соответствует контакторам вообще, чем любым другим коммутационным аппаратам, поэтому считают, что он удовлетворяет (когда уместно) требованиям к контакторам.

latched contactor
a contactor, the moving elements of which are prevented by means of a latching arrangement from returning to the position of rest when the operating means are de-energized
NOTE 1 – The latching, and the release of the latching, may be mechanical, electromagnetic, pneumatic, etc.
NOTE 2 – Because of the latching, the latched contactor actually acquires a second position of rest and, according to the definition of a contactor it is not, strictly speaking, a contactor. However, since the latched contactor in both its utilization and its design is more closely related to contactors in general than to any other classification of switching device, it is considered proper to require that it complies with the specifications for contactors wherever they are appropriate.

contacteur à accrochage
contacteur muni d'un dispositif d'accrochage empêchant ses éléments mobiles de retourner à leur position de repos quand on cesse d'actionner le dispositif de commande
NOTE 1 – L'accrochage et le déclencheur d'accrochage peuvent être mécaniques, électromagnétiques, pneumatiques, etc.
NOTE 2 – Du fait de son accrochage, le contacteur à accrochage possède en fait une seconde position de repos et, d'après la définition du contacteur il n'est pas à proprement parler un contacteur. Cependant, étant donné que le contacteur à accrochage, tant par son utilisation que par sa conception, se rapproche davantage d'un contacteur en général que de toute autre sorte d'appareil de connexion, on admet qu'il réponde aux spécifications des contacteurs dans la mesure du possible.
